Title: Improvements in or relating to hydraulic drives
IPC: F01L25/08
Filed: 1959-12-29
Abstract: 884,388. Hydraulic machines. KLOPP, F. Dec. 29, 1959 [Jan. 5, 1959], No. 44119/59. Addition to 881,361. Class 69 (2). [Also in Group XXII] An hydraulic drive for rectilinear reciprocating motions of a machine such as a machine tool, comprises a pump G1 which is connected to the chambers of a cylinder 1 for reciprocating a piston K1 and is infinitely adjustable through a neutral position to two extreme limits to effect forward and reverse flow of liquid by a control element 11 itself movable between two extreme limits by a reversing valve K4 actuated by a control pump G2, and a feed device which is simultaneously actuated with the switching of the reversing valve by a ratchet means 204 between the reversing valve and the feed device or by oil discharged from the reversing valve during switching thereof. The reversing valve and the control element are guided by pins 8, 12 in the guideway of a crank 9 the pivoting point of which is adjustable by means of a spindle 16 for varying the magnitude of the movements. When the piston K1, Fig. 1, reaches the end of its upward stroke, an abutment A2 operates a switch T2 to energize a magnet M3 to move a pre-control valve K3 to the left. Fluid from the control pump G2 then passes through a line 39 to move the reversing valve K4 to the right to reverse the pump G2 and the direction of movement of the piston KI. During the movement of the reversing valve, a rack 202 on a rod 201 of the valve drives the feed device through a pinion 203 and ratchet wheel 204. The fluid supplied by the control pump G1, after moving the valve, effects the flushing and cooling of the fluid in the circuit 29, 32 between the pump G1 and cylinder 1 as described in the parent Specification. In an alternative embodiment, at the end of the stroke of the piston K1, Fig. 2, the movement of the pre-control valve K3 connects fluid delivered to a line 91 from a pump ZP to a line 93 to move the valve K4 to the left and reverse the output from the pump G1 and the direction of movement of the piston K1. During the movement of the reversing valve, fluid from the left-hand end is discharged into a line 104 connected to the pre-control valve K3 and a line 127 leading to an on-off valve K9 and a direction-control valve K7 of a feed motor VM.

Abstract: 1440089 Automatic control of speed PAPST-MOTOREN KG 21 Sept 1973 [19 Oct 1972] 44350/73 Heading G3R [Also in Division H2] A brushless motor for directly driving a phonograph turn-table has its speed controlled by a control circuit wherein the voltages induced in the individual armature windings when not carrying current are detected and added to a derived out of phase second voltage to produce a control signal for keeping the speed of the motor constant. In the arrangement shown the sunusoidal voltage induced in each stator winding 10-13 when not carrying motorring current, is rectified and added by means of the polyphase half-wave rectifier bridge and resistors 35-38 thereby increasing the frequency modulation and thus reducing the ripple content of the fed back voltage. This voltage is applied to the inverting input of amplifier 44 and compared with the reference voltage applied at the non-inverting terminal. Amplifier 44 has a feedback circuit 50 comprising a damping or filtering circuit. The output of amplifier 44 controls the conductivity of transistor 24 and thus the current flowing in the armature windings when the respective transistors 18-21 are made conductive by the action of the rotor magnetic field on Hall plates 14, 15. The resistors are made adjustable so that the frequency modulation of the fed back signal can be doubled.

Title: Vehicle suspension employing hydraulic shock absorbers
IPC: F16F9/48
Filed: 1974-10-15
Abstract: 1489350 Telescopic dampers VOLKSWAGENWERK AG 15 Oct 1974 [16 Oct 1973] 44542/74 Heading F2S When the piston of a telescopic damper approaches an end of the cylinder, the subsequent movement away from the end is heavily damped. The dampers are installed to act in parallel with a vehicle suspension in such a way that movement of the piston away from the abovementioned end takes place during loading of the suspension and the additional damping comes into force only when the vehicle is braking or cornering. In the embodiment of Fig. 1, the piston 2 has a spring-biased non-return valve 7, 8 for each direction of motion, and near the end 5 of the cylinder there is a spring-biased plate 10. Should the piston approach the end 5, the plate 10 abuts the valve element 8 to increase the bias holding it closed. This does not affect the fluid damping of further movement towards the end 5, since this is controlled by valve 7, but the subsequent movement away from the end 5 is more heavily damped because of the increased bias on the valve element 8. There may be a similar arrangement at the other end of the cylinder. In the embodiment of Fig. 4, the piston 21 has a spring-biased non-return valve 24, 25 for each direction of motion, and carries a piston extension 26 which when the piston approaches the end 30 of the cylinder comes into cooperation with a cylinder part 28. Further movement towards the end 30 is substantially unaffected by this piston/cylinder arrangement, since liquid can escape from the annular chamber 29 through a non-return valve (31, Fig. 5, not shown) to the space 33 and thence past the valve 25. However the subsequent movement away from the end 30 is more heavily damped since liquid flowing past the valve 24 and into the chamber 33 can flow to the chamber 29 only via the passage 27, which may be tapered (Fig. 5). There may be a similar arrangement at the other end of the cylinder.

Abstract: 1457079 Cigarette lighters MANSEI KOGYO KK 17 Oct 1974 [18 Oct 1973 28 Dec 1973] 45116/74 Heading F4T The actuation of a gas-fuelled cigarette lighter is achieved by a cylindrical member 18 which is substantially the same diameter as the casing and which rotates about the central longitudinal axis of the casing and which is mounted on a block 10 located on the fuel tank 2. In the first embodiment the cylindrical member 18 (Fig. 4) has a cam surface on its inner surface which co-operates with a pin 15 slidable in slots 14. Rotation of the cylindrical member causes depression of the pin and actuation of a piezoelectric ignition system and opening of a valve to feed a burner 21. The valve can be held open by the pin engaging in depressions 25c in the cam surface. Alternatively the cylindrical member may have a pin fixed across its inner space and the cam surface may be on a longitudinally moving member which effects actuation. In another embodiment Fig. 8 the lighter is powered by a battery and incorporates an ignition circuit connected to a spark gap. The actuating-mechanism comprises the cylindrical member, (318 in Fig. 8) or cam 325 pivotable about a central pin 337 and an arresting member 340 pivotable about a pin parallel to the central pin 337. The cam and arresting member are biased towards each other by springs 339 and 342 respectively. Rotation of the cylindrical member causes the cam member to rotate and actuate the valve. The arresting member and the spring 339 form a switch for the ignition circuit. In yet another embodiment incorporating battery ignition, the cylindrical member 418 in Fig. 12 has attached thereto a pusher 415 which upon rotation closes a switch in the ignition circuit and actuates the valve.

Abstract: 987,357. Automatic position control. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18,1963 [Nov. 30,1962(2);Dec. 18,1962],No. 45363/63. Heading G3R. [Also in Divisions G5 and H1] A memory system comprises: a magnetic recording medium 11, Fig. 6 having a non-magnetic substrate and first and second magnetisable layers on which may be recorded data signals and servo signals;a transducer 10 for sensing the servo signals and for sensing and/or recording the data signals;and a servo system to effect relative movement between the medium and the transducer to bring the transducer to a predetermined position relative to the location of the servo signals,for sensing or recording the data signals. As described, servo signals of frequency F1 or F2 are recorded on the lower, high coercivity, layer on a number of concentric tracks, alternative tracks being the same frequency. The data signals are recorded on the upper, lower coercivity, layer, their tracks being spaced between those of the servo signal, Fig. 5. The output from the sensing coil 15 of transducer 10 is fed via a wide band amplifier 14 to filter amplifiers 16,17,18 which separate the data signal and the two servo signals. The two servo signals are then fed via gates 19, 20 to produce a control signal which positions the transducer 10 mid-way between two of the servo tracks. The gates 19, 20 are controlled by an address register 13 which determines which of the two frequencies F1, F2 is passed by the gates. If the transducer 10 is over an "odd" data track, then frequency F1 passes through gate 19 and F2 through gate 20. If on the other hand it is over an "even" track, F1 passes through gate 20 and F2 through gate 19.
