Title: A new or improved free-wheel differential gear
Filed: 1929-08-31
Abstract: 332,794. Myers, S. J., and Healy, J. Aug. 31, 1929. Differential gearing comprises twin ball or roller one-way devices adapted to prop or jam axially of the gearing. Thus two rings of balls e, Figs. 1 and 2, are adapted to jam between a driving- annulus a and two driven plates d, the latter being fast to the part-axles b of a vehicle. The balls e are seated in cam recesses a' in annulus a and may engage annular recesses d' in the plates d, which are thrust during driving into frictional engagement with the side plates c of the differential casing. When the ball cages # are uncoustrained, the balls can jam in both directions and the differential is locked. To free the differential, the relative movement of the cages # is limited, and this is done by turning a trip spindle i carried by the casing c so as to bring eccentric bosses n upon the spindle into engagement with recesses #<1> in the cages #. This is done by turning down a trip lever k by lowering a control plunger stop t manually &c. The lever k is loose on the spindle i and acts to turn the latter through a pawl ! l fast thereto. A spring m, Fig. 3, turns the pawl one way, and a projection k<1> on lever k turns the pawl the other way. Thus the differential is rendered locked or free by raising or lowering plunger t, which is struck by lever k next revolution. During reversed driving, the differential is automatically locked. A cam pawl v pivoted in a slot t' in plunger t during forward driving slips idly over a rail c<1> on casing c. On reversing, the pawl v is engaged by a recess c<2> in the rail and turned so as to cam the plunger t upwards, so raising the trip mechanism and removing constraint from the ball cages. An arrangement is described for allowing limited relative angular displacement between the cagecontrolling bosses n.

Title: Improvements in or relating to machine tools for machining rotating work pieces
IPC: B24B5/06
Filed: 1953-09-28
Abstract: 727,223. Grinding-machines. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Sept. 28, 1953 [Sept. 29, 1952], No. 26649/53. Class 60. [Also in Group XXII] A machine for grinding rotating work-pieces 31, Fig. 3, such as the inner race rings of ballbearings, has a number of work-spindles 3 mounted in a carriage 7, a number of tools 6 mounted on a carriage 4, Fig. 1, for simultaneously working on a number of work-pieces, means for bringing each work-piece in turn into working position with respect to each toolholder and means for effecting a relative feeding movement between the work-pieces and tool holders. In the preferred embodiment, three work-pieces are treated simultaneously by three grinding-wheels 6, Fig. 4, driven by a motor 5 mounted on the carriage 4 which is reciprocated axially by a crank device 16 driven through belt drives and bevel gears by an electric motor 15. When the operation on each work-piece has been completed, the carriage 4 is retracted, and the carriage 7 carrying the work spindles 3 is indexed through 90 degrees by a pawl 12 secured to a ring 11 operated by a hydraulic motor 8. In timed relation with the indexing, a fluid-pressure operated piston 17, Fig. 5, rocks a pair of pawls 20, one of which rotates a shaft 18 which, through a screwthreaded connection, lifts a stop-member 22a co-operating with adjustable stop-members 23 and hence permits the motor 8 to rotate the carriage 7 through a further small angle to apply depth of cut feed. The return stroke of the piston 17 causes the other pawl to rotate the shaft 18 through a smaller angle in the reverse direction so that the stop member 22a is displaced from its original position to compensate for wear of the tools 6 after each grinding operation. During indexing, the stop member is swung clear of the carriage 7. The three work spindles opposite the tools 6 are engaged by a common chain drive from an electric motor 13 while a fourth spindle occupies an idle position at which the work-pieces are replaced by a pneumatically-operated device. A bore gauge 24 mounted in each work spindle 3 is reciprocated in time with the movements of the tool when the spindle is indexed to the final grinding position and is arranged to initiate the indexing operation when the work-pieces reach the required size.

Abstract: 645,947. Super-regenerative receivers. STANDARD TELEPHONES & CABLES, Ltd. Oct. 6, 1947, No. 26806. [Class 40 (v)] [Also in Group XL (a)] A super-regenerative receiver for high-frequency electromagnetic waves comprises an electron discharge device of the travelling wave amplifier type, a cavity resonator in which quenched oscillations of the incoming wave frequency are set up, and means for detecting said quenched oscillations, said cavity resonator being excited by means of the emergent electron beam from said travelling wave amplifier, said oscillations being quenched and regenerated by the alternate attraction and repulsion of said beam to or from an electrode associated with said cavity. The travelling wave tube 1 has a glass envelope 2 having a bulb at one end, surrounding and supporting an electron gun 3 consisting of an indirectly-heated cathode 7, control grid 8 and focusing anode 9 and a tubular portion surrounding and supporting (by means not shown) a wire helix 4, and is sealed at its end to a cavity resonator 5. One end of the helix is connected to a hollow cylindrical stub 16 which is supported by insulators 17 in the neck of the glass-envelope 2, and the other end brazed to the wall of cavity resonator 5. Focusing may be assisted by coils 10 and 11. The incoming modulated wave energy is fed into the helix pick-up space 12 by means of a rectangular wave-guide 13 terminated by a rectangular cavity 14 having a tuning piston 15. Part of stub 16 together with flanged extensions 18 of the wall of waveguide 13 form a quarter-wave sleeve. Cavity resonator 5 is provided with extensions 20 and 21 of envelope 2 sealed to its walls to allow mechanical tuning, and has a terminal connection for the application of suitable polarizing potentials to the helix. The potential of the electrode 22 is made alternately positive and negative by a rectangular voltage wave-form applied at terminals 33 and 34. The resulting quenched oscillations in cavity 5 are picked up by a loop 23, rectified by a crystal detector 24 and the resulting modulation signal passed through a low-pass filter 35 to output terminals 36 and 37.

Title: Anti-Surge Flow Control Valve
IPC: F15B13/04
Filed: 1967-06-09
Abstract: 1,193,702. Valves. ABEX CORP. 9 June, 1967 [7 July, 1966], No. 26826/67. Heading F2V. [Also in Division F1] In an hydraulic circuit linking a reservoir 11 and a motor 16, there is incorporated a pump 12, a variable direction-control valve 17 and an adjustable volume, constant flow control valve 10, the latter valve also serving to prevent pressure surges from being applied to one side of the motor. Upon fluid pressure being applied to the inlet 75 of valve 30, which serves to maintain the flow constant, such pressure acts through a restrictor orifice 85, formed in a check valve 78, 81, through lines 83, 84 and within a chamber 72 tending to urge a piston 56 towards its stop ring 52, the other side of the piston being subjected to the outlet pressure via line 103. As the pressure differential across the piston 56 exceeds a certain predetermined value, the piston moves upwardly imparting similar movement to a substantially T-shaped valve member 43, such motion resulting in communication being established, via a groove 46 formed in the valve member, between the inlet 75 and an outlet 42, the degree of communication being determined by the relative strength of various forces acting on the valve member, these forces being due to springs 50, 61, the inlet pressures acting in chambers 49 and 72, and the outlet pressure acting in chamber 69. Fluid from the outlet 42 is then conveyed to a manually and independently operable valve 31 having an axis transverse to that of valve member 43 and comprising a sleeve 89 which has formed therearound a groove 90 which is intersected by a rectangular slot 94 and has axially and rotatably movable therein a slotted piston 95, the arrangement being such (Figs. 2, and 5, not shown) as to permit the volume of fluid entering lines 97 and 20 to be varied by cooperation of piston 95 with slot 94. Reverse movement of the motor is effected by changing the state of valve 17 as a result of which fluid is applied directly to the motor via line 24, fluid discharged from the motor is returned to tank via line 21, and the components of valve 30 are returned to the position shown, fluid from chamber 72 being returned to the inlet via the check valve 78, 81.
