A constant-speed hydromechanical drive for aircraft accessories compriss input and output shafts 13, 92 geared to back-to-back hydrostatic units 112, 113 and an interposed elongated mechanical epicyclic gear unit 65. Hydraulic system.-The units 112, 113 are of the swashplate type, the former being of variable capacity controlled by a servo unit 156, while the latter is of fixed capacity. Pressure liquid is supplied through a pipeline 310 from a charge pump (181) via a bypass valve (303), filter (308) and cooler (327), Fig. 3A (not shown), a second line 200 connected to servo unit 156 also communicating with a pressure regulating valve 315 and a scavenge pump 180. A line 203 branching from line 200 and a further line 208 connected to servo unit 156 communicate with an output driven centrifugally controlled governor valve 204, Fig. 3C (not shown). Epicyclic gear unit.-An input shaft 68 carries intermeshing elongated planet pinions 79, 80 on shafts 73, 76 and whose ends respectively mesh with an output ring gear 85 and a control ring gear 95. The ends of shafts 73, 76 are carried by blocks 77, 78 disposed in transverse openings 69, in a housing member 66, integral with the input shaft 68, Fig. 6 (not shown). Ring gear 95 is coupled to hydrostatic unit 113 by meshing pinions 126, 128 and the input shafts 13, 68 are coupled by pinions 63, 67. The unit 65 is also coupled to hydrostatic unit 112 by pinions 72, 115 and to output shaft 92 by pinions 89, 90. Operation.-With swashplate 120 of unit 112 in the zero-displacement position the unit 112 and control ring 95 are braked against rotation to give direct drive through gear 65. If the output speed falls governor valve 204 operates to admit pressure liquid to servo 156 to adjust swashplate 120 so that units 112, 113 act as pump and motor respectively, control ring 95 thus being rotated in the opposite direction to input shaft 68 to add speed in gear 65. With increased output speed the setting of swashplate 120 is reversed so that unit 113 acts as a pump driven by ring 95 and speed is reduced to the desired value. The epicyclic gear unit 65 forms the subject matter of Specification 1,108,022.

Abstract: 932,754. Protective cut-out arrangements. WHIPP & BOURNE Ltd., and C. L. WHIPP. Oct. 30, 1959, No. 36839/59. Class 38 (5). A control system for a circuit-breaker or contactor comprises a release and operating coil C, a low-voltage relay A for providing a shortcircuit path through the coil C and overloadresponsive relays having contacts E11, E21 for providing a second short-circuit path through the coil C, the D.C. resistance of the second path being greater than that of the first, so that the flux produced by the coil C decays more rapidly in the event of an overload than it does in the event of low voltage conditions and the release of the circuit-breaker or contactor is quicker in response to overload than it is in response to low voltage. When normal voltage exists at the leads L3, L4, the relay A changes over its contacts A1 The circuit-breaker or contactor may then be closed by operation of a switch S2 to energize the coil B of a closing contactor which closes contacts B1 to energize the coil C. The circuit-breaker or contactor closes auxiliary contacts C5, C6 to prepare the short-circuit paths, closes auxiliary contacts C7 to complete a retaining circuit and opens contacts C8 to deenergize the coil B of the closing contactor. When the relay A releases under low voltage conditions, contacts A1 complete the first shortcircuit path through normally closed contacts E12, E22 of the overload relays and the contacts C6. Under overload conditions either or both of the contacts E11, E21 are closed to complete the second short-circuit path through the contacts C5 and a resistor R2, and either or both contacts E12, E22 of the overload relays are opened to prevent completion of the first short-circuit path. The circuit-breaker or contactor may be opened by manually closing a switch S1 to complete a third short-circuit path through resistors R2, R3. The relay A may be supplied through a rectifier. To prevent hunting of the circuit-breaker or contactor, the system may be provided with anti-hunting relay circuit of Specification 917,631.
