Abstract: 977,638. Change-speed gear and control; friction clutches. FICHTEL & SACHS A.G. Jan. 17, 1962 [Jan. 17, 1961], No. 1689/62. Headings F2C and F2D. [Also in Division D1] A two-speed countershaft gear for a washing machine comprises a contracting clutch coil spring 11 engaged with hubs on an electric motor shaft 1 and a driven shaft 2 for direct drive in one direction when the washing machine basket is used for drying, and a roller ratchet clutch 8 transmitting drive for washing at a reduced ratio through a gear train 4 . . . 7 when the clutch coil 11 is disengaged, the roller ratchet clutch 8 transmitting drive in both directions of rotation and also allowing overrunning in both directions. Accordingly, when changing from direct drive to the reduced ratio, the inertia of the washing machine basket &c. does not drive back through the countershaft train 7 . . . 4 to rotate the electric motor shaft 1 at a speed faster than normal. The clutch coil spring 11 is fast at one end 13 with a surrounding sleeve 12 and abuts at its other end a stop 15 secured to a disc 14 carried on the motor shaft 1. The stop 15 engages with lost motion in a notch 26 in the sleeve 12, and is fast with one end of a torsion spring 16 secured at its other end to the sleeve. The arrangement is such that the torsion spring 16 unwinds the coil spring 11 for clutch disengagement. Energization of a solenoid 19 projects a stop 18 into the path of a radial arm 30 on a friction drag ring 17 surrounding the sleeve 12, so that if the motor shaft 1 is rotating in the correct direction, the sleeve is turned against the bias of the torsion spring 16 and the coil spring 11 is wound on to the hubs at the adjacent ends of the motor and driven shafts 1, 2. The roller ratchet clutch comprises rollers 8 in a cage 9 rotating against the bias of a friction drag spring 10, the rollers engaging the shaft 2 to permit its over-running in either direction and also engaging in symmetrical cam pockets in the gear 7 to transmit drive in either direction. Change of speed may be effected automatically in sequence by means not further described, or manually.

A casting process comprises passing through the molten metal during solidification a neutral or reducing gas, e.g. argon, which is insoluble in the melt, the gas being passed in a controlled stream of finely divided bubbles from bottom to top of the mould so as to flush non-metallic inclusions to the top. The gas may be led into the mould through a porous stone in the bottom thereof or produced by the vaporization of material, e.g. magnesium, lithium, introduced into the melt in a finely divided state. The gas may serve as a carrier to introduce additional materials for e.g. alloying, deoxidation or desulphuration.

Title: Improvements in hydraulic shock absorbers
IPC: F16F9/26
Filed: 1937-01-22
Abstract: 469,984. Hydraulic shock-absorbers. GENERAL MOTORS CORPORATION. Jan. 22, 1937, No. 1939. Convention date, Jan. 24, 1936. [Class 108 (iii)] A double-acting hydraulic shock-absorber comprises a fluid reservoir 22, two fluid-displacement chambers 24, 25 having devices, such as spring-loaded valves 40, 46, for con-, trolling the flow of fluid therefrom, and a fluidreplenishing device adapted to be actuated by the pressure in one of the chambers to open the other chamber to the reservoir and permit fluid to flow from the reservoir into the other chamber. As shown, the valves 40, 46 are contained in chambers 35, 36 connected directly by passages 37, 38 respectively with the chambers 25, 24, the chambers 35, 36 also being connected through conduits 47, 48 respectively with the passages 38, 37. The fluid-replenishing device comprises a block 60 having a longitudinal passage 67 adapted when the block is fitted into a recess 50 in the shockabsorber casing to be in alignment with a passage 51 leading to the reservoir. A transverse bore 62 in the block provides communication between the passage 37 and a passage 53 connecting the recess 50 and passage 38, a valve-stem 70 slidably supported in the bore 62 by means of spaced rectangular flanges 73, 74, being provided at each end with a flexible disc 80 or 91 and a saucer-shaped backing-plate 82 or 83, the discs normally engaging valve seats 65, 66 to prevent communication between the passages 52, 53 and bore 62. In operation, when the piston 2 is moved, for example, to the left by the operating cam 32, the fluid in chamber 24 flows through passage 38, past valve 46, into valvechamber 36, and through conduit 48 and passage 37 to chamber 25. Should leakage of fluid past the piston occur, a full supply is not delivered to the chamber 25 and accordingly when the piston moves to the left fluid is forced also through the passage 53 and exerts a pressure on the end of the replenishing valve causing the disc 80 to be flexed and the entire valve assembly to move bodily towards the right, thus lifting the disc 81 from it seat 66 and connecting the passage 52 with the bore 62 and passage 67. Accordingly, the suction created in chamber 25 draws fluid from the reservoir 22 through the passages 51, 67 and bore 62, past the disc 81, and through the passages 52, 37 to replace the leakage fluid. The operation is similar but reversed when the piston 23 moves to the right.

Title: A device for the distribution of electrical pulses

Filed: 1955-01-21
Abstract: 764,447. Thermionic distributers. PINET, A. E. Jan. 21, 1955 ]Jan. 26, 1954], No. 1966/55. Class 40 (3). [Also in Group XL (c)] In a device for the distribution of electric pulses in a multiplex pulse transmission system the pulses are applied via an electron discharge tube to the input of a delay line which is shorted at its distant end and has its input end terminated in its characteristic impedance when a rectifier connected in series with a resistor across the input to the line is conducting. Pulses are tapped off along the delay line and connected to corresponding utilization circuits. The Figure shows a device for distributing electrical pulses to the channel modulators of a known type of multiplex pulse transmitter, the output from a control pulse generator 1 is applied via tube 2 to the input terminals 13<1>, 14 of a delay line 21 which is shorted across its distant end at 16. The negative-going pulses which are fed into the input of the line are n tapped off at points 13<1>, 13<2> ... 13 - and applied 2 n to the channel modulators 19<1>, 19<2> ... 19 - 2 to the input of which the signals to be multiplexed are also applied the outputs being connected in parallel to a transmission line 12. The negative pulses are reflected and have their plurality reversed at the short-circuited end 16 of the transmission line and are propagated back down the line as positive pulses and are finally absorbed in the circuit 17, 18 since the rectifier 8 conducts and the resistor 17 is equal to the characteristic impedance of the line. As the positive pulses pass down the line they are tapped off at points 13 n/2, 13 n/2 - 1 ... 131 and are applied by phase-reversing transn n formers 20 -, 20 - - 1 ... 20<1> to the channel 2 2 n n modulators 19 - + 1, 19 - + 2 ... 19n to the 2 2 input of which the signals to be time multiplexed are applied and the outputs of which are connected in parallel to transmission line 12. Thus by means of the invention a delay line having a length only half of that normally required is used.

Title: Scoop Trimmed Hydraulic Turbo Couplings

Abstract: 1,172,861. Hydrodynamic couplings. FLUIDRIVE ENG. CO. Ltd. 16 Jan., 1967 [18 Jan., 1966], No. 2379/66. Headings F2C and F2L. A scoop trimmed turbo coupling is controlled by two scoop tubes, a scoop tube 17 which normally determines the quantity of liquid in the working circuit and thus the torque transmitted, and a quick emptying scoop tube 23 which is operative only on the occurrence of an abnormal operating condition necessitating rapid reduction in the torque transmitted by the coupling. The scoop tubes are controlled respectively by hydraulic or pneumatic servos 22, 25, the pressure supply to the servo 25 for rapid emptying of the coupling also being applied through a conduit 26 to actuate a valve 14 and thus shut off supply of liquid to the coupling from a supply pump 12. The scoop tubes pass the oil via a de-aerator chamber 21 to a sump. As shown the quick emptying scoop tube remains in its retracted position until required, for example upon rise in temperature of the coupling fluid or on loss of supply voltage to a synchronous motor driving the coupling. In a modification the scoop tube 23 is connected by a lost-motion connection to the scoop tube 17 and biased by a spring to a position nearer to the coupling axis than the tube 17 so that the tube 17 normally controls the filling of the coupling. On actuation of the servo 25 scoop tube 23 is advanced against the pressure of its spring to rapidly empty the coupling.
