Speed reducer and housing therefor

Abstract: A speed reducer is contained in a modular housing that includes a body having a chamber for mounting the gear train and power shafts and which is open at two opposing ends, an end member for mounting the speed reducer and forming an oiltight seal with the body at one of the ends, and another end member forming an oiltight seal with the body at the other of the ends.

Redundant motor reducer drive

Abstract: A compact in-line dual motor arrangement provides a redundant drive system wherein the respective motors are coupled to planetary gear reducers, each preferably of the dual harmonic drive type. The construction is such that in one stage a first drive motor and one of its two circular splines are connected to a stationary housing, and the second output circular spline is integral with a first circular spline of the second stage. The second circular spline of the second stage transmission together with the second drive motor are connected to an output member.

Drag reducer for land vehicles

Abstract: A drag reducer for a gap in a land vehicle moving through air which consists of a retractable or articulated baffle, spanning approximately the entire distance of the gap. The drag reducer can be used on all land vehicles and is readily adaptable for use on railroad box cars, truck semitrailers, full trailers in tandem and vehicles towed by cars. The drag reducer can take the form of a fin mounted rigidly or with articulated joint or flexible material to allow for movement between the leading and trailing vehicles. It may also be of a retractable nature, such as an accordian arrangement, a roll-up screen, an inflatable fin, a folding plate, etc. The unit may be attached primarily to either the lead vehicle or trailing vehicle or both, however, in the case of tractor-trailer trucks, the bulk of the device is better kept with the tractor unit, because there are approximately one-third the number of tractors compared to trailers, resulting in substantial savings in the cost of equipping fleets of tractor-trailer rigs.

Control and signal arrangement for respirators

Abstract: A control and signal arrangement for respirators which includes a service or supply block provided with bores for receiving a pressure reducer and/or an alarm mechanism. The pressure reducer and/or the alarm mechanism are fashioned as individual detachably mounted modules. The supply or service block communicates with a compressed gas reservoir with at least one supply bore being provided in the supply block for communicating the compressed gas reservoir with the pressure reducer and/or the alarm mechanism. The pressure reducer module and/or the alarm mechanism module includes radial bores which function as gas supply bores. The radial bores terminate in continuous grooves extending around the individual modules whereby the modules can be inserted into the supply block independently of any specific angular position.

Internal gear set having roller teeth

Abstract: Internal gear set comparable to a geroter gear set except that all teeth are provided by rollers positioned in slightly oversize pockets. The internal gear set may have two, three or more gear members to provide, respectively, one, two or more sets of expanding and collapsing chambers and may be used as a hydraulic motor, pump and/or speed reducer.

Ion implanting device

Abstract: PURPOSE:To provide a compact device by providing a speed reducer of ion beam energy between an ion source and a mass separator, and keeping the beam transporting space between the ion source and the speed reducer at a negative high voltage. CONSTITUTION:Attention is paid to the negative voltage space between an ion source 1 and a speed reducer 5. Ant ion beam collides with a residual gas or wall within this space to generate a large quantity of secondary electrons. However, the secondary electrons are carried on a mass separator 2 side having a high voltage. Thus, the secondary electrons which neutralized the space charge of the ion beam in this space is eliminated, the ion beam is highly diverged by its own space charge, and collided with the wall in the space to loose the current. Since the beam aperture is also increased by the divergence, the beam transmitting efficiency of the speed reducer 5 is also reduced. To prevent the outflow of the secondary beams, an electrode having a voltage lower than the negative voltage of line space is arranged as one of the electrode voltages of the speed reducer 5, whereby the outflow can be prevented. Thus, the effect of neutralizing the ion beam space charge by the secondary electrons can be kept.

Pressure reducer device

Abstract: A pressure reducer device, particularly for hydraulic brake systems in motor vehicles comprises a housing having a chamber, a differential area piston movable within the chamber having a passage through which pressure is transmitted from a high pressure chamber to a low pressure chamber, and a sleeve fixed to the housing and disposed in the high pressure chamber. The differential area piston is movable in the sleeve to open and close the passage to perform a pressure modulating operation on the fluid transmitted from the high pressure chamber to the low pressure chamber.

Domestic water control unit

Abstract: A control unit is formed of a housing containing a filter with an inlet and outlet in line above the filter, the latter forming a channel with the housing; a pressure reducer is positioned between the inlet and the outlet above the filter. A rotary valve positioned between the filter and the pressure reducer reverses the flow in the unit. A plug-valve is located in the housing to provide drainage and the plug-valve is connected to the rotary valve so that on reversal of flow, the plug-valve opens to drain the unit.

Engine speed reducer responsive to positioning of the transmission shift lever

Abstract: An engine speed reducer responsive to positioning of a transmission shift lever which selectively determines the vehicle speed range and its direction of travel includes an apparatus operatively associated with a control linkage for moving it in a direction to decrease the speed of an engine from a predetermined high speed to an intermediate speed. An actuating device is operatively connected to the apparatus and is operative in response to shifting of the transmission shift lever to a reverse speed setting automatically to actuate the apparatus so that the engine speed is reduced.

Vacuum reducer valve assembly

Abstract: A vacuum reducer valve assembly senses the engine induction passage vacuum and delivers a reduced vacuum signal to a vacuum motor which advances the ignition timing in proportion to the vacuum signal. The vacuum reducer valve assembly has a member which decreases the difference between the induction passage vacuum and the reduced vacuum signal as atmospheric pressure decreases.

Remote control apparatus for channel selector

Abstract: A remote control apparatus for operating the channel selector of a television receiver, the apparatus comprising a drive motor connected to a gear reducer, the gear reducer being drivingly connected to the shaft of the channel selector, a switch for the drive motor, the switch being at the end of a length of cord to allow the switch to be located remotely of the receiver, and a stabilizing means to prevent rotation of the gear reducer with respect to the receiver.

Expanding fuel pipeline protection bypass valve system - has bypass pipeline with a nonreturn valve opening in outlet direction

Abstract: The bypass system prevents the fracture of a pipeline which is arranged between a storage tank containing liquid hydrocarbon such as petrol, butane or propane and a user. The delivery pipeline has a closing valve and a pressure reducer. The bypass protection line is used to cover the situation when the safety release valve of the system is not able to cope with the pressure increase in the pipeline. The situation is especially critical when liquid hdyrocarbon fuels are used. The pressure within the pipeline can be increased enormously due to temperature variations. the protected pipeline has two parallel lines one of which contains the closing valve and the other parallel line contains a non-return valve which is closed in the flow direction from the storage tank to the user.

Lignite lump grading machine - directs those above given size to reducer and has two reception units

Abstract: The incoming lignite is separated into two batches, the first of lumps bigger than a given size, and the second smaller. The first batch is delivered to a reducing unit producing lumps smaller than the given size. These, together with those in the second batch, are delivered to a first receiving unit. A second receiving unit is also provided, to which the first batch can be alternatively directed, the flow from the separator to the reducer unit being simultaneously interrupted. The reducer can incorporate a mechanism dividing the incoming material lumps into sizes greater and smaller than a second predetermined figure.
