Reducer coupling and positioner tool for the coupling

Abstract: The invention disclosed herein includes a reducer coupling, a positioner tool for connecting the coupling to a conduit section, and a nut for securing the positioner tool to the coupling. The reducer coupling is useful in various operations, such as some oil field operations in which it is used to connect a smaller conduit (delivery line) into a larger conduit (production casing). In practice, the positioner tool is secured to the reducer coupling and the coupling is moved into its hook-up position above the production casing, by attaching a rig to the positioner tool. The coupling can then be threaded into the casing by turning the positioner tool with a wrench, or similar tool.

Multiple stage gearbox shiftable under load

Abstract: A change spur gear of reducer unit design features two paths of force. The first path of force comprises a unit which provides gearing to high speed, a hydrodynamic torque converter and, following it, a multiple shift gear. The second path of force comprises as well a unit which provides gearing to high speed, on the high speed shaft of which there is a hydrodynamic servoclutch arranged. The secondary vane wheel connects through appropriate reducers with the transmission output. In shifting from one gear to another, the servoclutch is filled first, then the respective shift detent is disengaged under no load, the servoclutch is adjusted to the slip corresponding with the next gear thereby enabling a no-load shifting of the detent of the next gear. Upon emptying of the servoclutch, the engine moment is again assumed by the first path of force without any interruption of the traction force.

Night vision systems

Abstract: A night vision system 1 has a large image intensifier device 2 coupled to a video camera 5 by a fibre optic reducer 6, whereby the size of the image is reduced to match the size of camera tube 4 without significant loss of brilliance. A conductive screen 20 (Figure 3) covers the input face of the reducer 6 and is used to leak electron charges to earth whereby any electric interference is reduced. Magnets may be attached to the reducer 6 in order to reduce geometric image distortion. Control arrangements for the intensifier 2 and video camera 5 are described (Figure 4). Visibility of a partly submerged object e.g. a loy can be enhanced by stretching the image in a vertical plane.

Automatic faucet device

Abstract: PURPOSE: To produce an automatic bib device whose motor function and circuit are simplified by providing some play between a driving shaft and middle driving body. CONSTITUTION: A driving shaft 52 is connected with a motor 53 through a middle driving body 81 and reducer 58, and the middle driving body 81 is composed of an approximately kitchen knife-shaped driving plate 55 and two returning plates 61. The driving plate 55 is mounted pivotally in vertical direction on a shaft 54 near the driving shaft 52, and a projected roller 56 provided on the side of the tip of the driving plate 55 is fitted with free vertical movement in the vertically long hole 57 of the driving shaft 52. After the motor 53 has driven the middle driving body 81, a spring 65 automatically returns the middle driving body 81 to its original position. Consequently, the motor 53 may be rotated in only one direction for the one action of a drive control section 2 without returning the middle driving body 81 to its original position by reversing the motor 53, and the rotational function of the motor 53 can be therefor simplified.

Damping force variable shock absorber device

Abstract: PURPOSE:To prevent both squat and nose dive phenomena from occurring, by outputting an external signal for selection of damping force at a time when engine load is out of the specified range, while making the specified range so as to be expanded in proportion as the detected gear ratio becomes small. CONSTITUTION:When an engine's load 1, a car speed and detection signals Dp, Dr and Dc of a clutch 3 are all inputted into a microcomputer 30, an arithmetic unit 32 renews fuel pulse signals in regular sequence and stores them in memory one after another, while is judges a clutch engagement state through a clutch signal Dc, and calculates a gear ratio G from a car speed Dv and the engine load Dp in time of clutch engagement. This gear ratio G is compared with each step gear ratio of a speed reducer and judges of what step gear ratio is the case, then it sets the setting value for judgement in order. And, if a squat state occurs, damping force is made to increase yet more but if there is no squat, the damping force is kept down to low. With this constitution, the squat in a car is prevented from occurring.

Built-in tank type hydraulic vibration reducer

Abstract: PURPOSE:To make a built-in type hydraulic vibration reducer exhibit an effective vibration reducing action by almost nearly equalizing the average sectional area of the tank with the effective sectional area of the right side hydraulic chamber of a piston. CONSTITUTION:One of two pullers 2a, 5a of a vibration reducer is engaged to a structure and the other puller is engaged to a piping to be vibration-reduced. When a piston 4 causes going or coming back movement due to temperature change the oil freely flows through two valves 8, 9 without restricting the movement of the piping, taking effect of vibration reducing action. When the piston 4 moves quickly by such as an earthquake the valve 8 or 9 closes depending on the direction of the piston movement, and the vibration is reduced by the action of the piston 4 to strongly press the oil. As a bellows 6c and a right chamber 1b have almost the same sectional area, a stable vibration reducing action is achieved despite the cantilever rod construction of the device.
