Gaseous blast reducer

Abstract: A gaseous blast reducer employs a membrane which is effective to contain aass of gas having properties different from air, in the vicinity of the source of the blast. The blast is forced to propagate through the mass of gas before propagating in the air. An acoustic mismatch caused by the difference in properties between the gas and air reduces or attenuates the blast.

Conveyor for particulate material

Abstract: PURPOSE: To eliminate material separation in such a way that mixed particulate material is pneumatically conveyed in dollop condition. CONSTITUTION: After pressurized air has been fed through a pneumatic inlet port P 1 into a tank 1, a ball valve 12 is opened, mixed particulate material in the tank is disgorged into a guide pipe 2, and the material is pneumatically fed into a reducer 3 under combined pressure of pressurized air which is breathed out of a nozzle P 2 of the pipe 2 and air which is fed into the tank. Mixed particulate material throttled and compressed through a main reducer 32 is made into dollop by binder action of plasticizer in the material. The massive particulate material is pneumatically fed into a conveying pipeline 5 under pressurized air, and it passes smoothly through bent portions 50 in the pipeline 5 by means that the dollop is slackened by air blown in through an air blower 6. Thereafter, it is resoldified by compression through back pressure during pneumatic dispatch, and finally after it gets into a hopper 4, the conveyance will be finished. COPYRIGHT: (C)1982,JPO&Japio

Automatic lift valve

Abstract: The lift valve comprises a body (1) in which is formed a cylindrical chamber (2) provided with a lateral inlet (14) and with an outlet (3). This chamber contains a piston (4) on which acts a spring (22) and which is solidly fixed to a rod (6) whose end constitutes a valve seal. The rod (6) is further provided with a cross-section reducer (9) formed, for example, by a perforated cylindrical bearing surface. The inlet aperture (14) opens out between the piston (4) and the cross-section reducer (9). The difference between the forces acting on the piston and on the cross-section reducer causes the piston to retract, thus opening the lift valve. The cross-section reducer seals the inlet aperture (14) to a greater or lesser extent.

High ratio speed reducer

Abstract: A high ratio speed reducer comprising a rotatable input shaft operatively coupled to an output shaft which rotates at a reduced speed in response to rotation of the input shaft.

Abstract: PURPOSE:To make possible the manufacture of titled pipe with various sizes from the bloom of large section, by specifying the sectional area, outer diameter, wall thickness, of the blank obtained from the polygonally sectioned bloom, by preparing the cylindrical blank from above blank with the press roll piercer, by reducing diameter of this cylindrical blank with two cross helical rolling mills, and by finishing with the finishing mill. CONSTITUTION:After heating the polygonally sectioned metallic bloom of sectional area A to a suitable temperature by the furnace 1, this bloom is supported by the mandrel, and is pushed into plural round roll calibers of the press roll piercer 2; hereby, the cylindrical blank, being bottomed at one end and bottomless at another end, is prepared. Hereupon, the outer diameter of the blank after being worked is specified to 1.1 root A-1.2 root A, and the wall thickness is specified to 0.2 root A-0.3 root A. Next, the pipe blank P is rolled by the cross herical rolling mill 3 so as to reduce the outer diameter to 0.6-0.9 times, and wall thickness to 0.10-0.25 times of outer diameter reduced by the rolling work. After that, the outer diameter of the pipe blank is reduced to 0.7-0.9 times by the cross helical rolling mill 4 under a specified condition, without inserting the plug, mandrel, etc., into the blank. This pipe blank is rolled by the mandrel mill 5, is heated to a suitable temperature, and then finish rolled by the stretch reducer 9.

Noise reducer in dda converter

Abstract: In a musical instrument in which a plurality of data words corresponding to the amplitudes of a corresponding number of evenly spaced points defining a cycle of an audio waveform are transferred sequentially from a waveshape memory in repetitive cycles at a rate proportional to the pitch of the tone being generated, apparatus is provided for reducing undesired frequency components resulting from the conversion of the digital signals into analog musical signals. The noise reduction apparatus applies optimal amplitude weighting values to a subset of the stored data words and adds these weighted values together to provide a new single value which is used for the output signal.

Tip off rate reducer

Abstract: Disclosed is a launcher-missile system with the launcher tube provided with a configuration on its aft end so as to reduce the tip-off rates of the system. The configuration comprises the formation of an open sector in the flared end of the launcher tube so that a portion of the exhaust gases exiting from the tube, as the missile is fired, does not impinge on that sector of the flared end and thus an impulse caused by the impinging of the gases on the remainder of the flared end reduces the tip-off rate. Also disclosed is a means in which the size and location of the open sector can be selected depending upon the desired change in magnitude and direction of the tip-off rate.

Roll drivivg device in continuous casting equipment

Abstract: PURPOSE:To enable the rotating speed differences of the upper and lower rolls of the captioned device to be changed in a stepless manner by suitably changing the rotating speed of the differential gear of the planetary gear mechanism provided to one drive shaft by an auxiliary drive machine. CONSTITUTION:When a sungear 18 is rotated in the arrow (a) direction by a main drive machine 27 and speed reducer 29, a planetary gear 21 revolves in the arrow (a) direction while rotating in the arrow (b) direction, causing the drive shaft 11 of the upper roll to revolve in the arrow (a) direction. The drive shaft 12 of the lower roll is also revolved in the arrow (c) direction by a transmission gear 30. In the arc part, there is a need for rotating the upper rool with a slight delay from the lower roll. This simply necessitates delaying the revolution of the gear 21 by rotating an auxiliary gear 26 in the arrow (d) direction by an auxiliary driving machine 22 and speed reducer 23 thereby rotating the differential gear 16 in the (e) direction opposite from the revolving direction (a) of the planetary gear 21.

Swivel head reaction bar nut runner - has torque reaction bar attached to gear housing for movement w.r.t. air motor housing

Abstract: The pneumatically powered nut runner has an axial swivel interposed i the housings of the air motor and gear reduction to permit radial repositioning of the gear reducer housing relative to the air motor housing. A torque reaction bar is affixed to the gear reducer housing and is thus also radially repositionable relative to the air motor housing. This repositioning capability facilitates adjustment of the reaction bar so that it contacts a bracing point without necessitating the radial repositioning of the air motor housing. When torque is applied to a fastener, nearly all reaction torque is taken by the torque bar and none is transmitted to the operator.
