Patent GB-413801-A (GB)
Title: Improved means for varying the compression ratio of compression-ignition oil engines
IPC: F02D15/04
Filed: 1933-03-07
Abstract: 413,801. Adjusting cylinder clearance. LISTER & CO., Ltd., R. A., and SANDERS, A. F., Victoria Iron Works, Long Street, Dursley, Gloucestershire. March 7, 1933, No. 6874. [Class 7 (ii).] In a constant-speed compression-ignition oil engine, the cylinder clearance is adjusted by means responsive to the amount of fuel injected, or the load. As shown in Fig. 1, a rod 18 is moved by the engine governor to adjust both the liquid fuel pump 17 and a valve 19 which admits fluid-stored under pressure in a tank 20, to one or other side of a plunger 24, a valve 15 being thus moved to open or close an auxiliary combustion chamber 13 as described in Specifications 322,097, [Class 7 (iii)], and 368,346. The side of the plunger 24 not acted on by the fluid is vented by an orifice 26. Fig. 2 shows an electric-generating set in which the valve 15 is moved in accordance with the load. When the load reaches one third of its full value, a load-responsive switch 32 closes a circuit through a relay 33, which, with a time delay due to a dashpot 34, closes contact 35 to energize a coil 38. This oscillates a butterfly valve 41 to the position shown in chain lines and thus causes suction in the induction pipe to draw a plunger 24, connected to the valve 15, to the left. The butterfly valve is, however, immediately returned to its neutral position, owing to the circuit being broken by a member 39 which is moved by the plunger to break contacts 40 and join contacts 46, the parts being thus placed in position to return the piston 24 when the load falls below one third of full load. A spring-pressed cam on the shaft 55 biasses the valve 15 to one of its extreme positions.

Title: Electric linear motion device
IPC: H02K41/035
Filed: 1969-02-10
Abstract: 1,260,913. Linear motors and generators. DATA PRODUCTS CORP. 10 Feb., 1969 [9 Feb., 1968], No. 7097/69. Heading H2A. A linear motion device, particularly a pick-up head positioner for a magnetic storage disc, comprises a core 20 having elongated air gaps 32 , 34 between a central limb 28 and upper and lower limbs 26, 30 along which a substantially uniform flux is generated by permanent magnets 36, 38, the central limb 28 being embraced by a drive-coil 50 coupled to a carriage 14 and which travels along the air gaps when excited by current passed through flexible leaf springs 56. To reduce the response time-lag caused by the inductance of drive-coil 50, the central limb 28 carries a bucking coil 70, a portion of which is connected in series with the drive-coil, e.g. by sliding contacts, Fig. 4 (not shown) and produces a field in the central limb opposing that produced by the drive-coil. To obviate the use of sliding contacts, the whole of a bucking coil with widely spaced turns is connected in series with the drive-coil, Fig. 5 (not shown). The central limb of the core, the drive-coil and the bucking coil may be circular in cross-section and the upper and lower limbs may carry arcuate polepieces to produce a greater flux concentration, Fig. 6 (not shown). The carriage 14 in Fig. 1 carries a coil 124 forming part of generator similar in construction to the motor described above. A rectangular core 110 supports a permanent magnet 122 and a bucking coil 128 on opposite limbs, the coil 128 being surrounded by the coil 124 which produces an output proportional to the linear velocity of the carriage. Fig. 7 shows a modification in which the core 150 is formed at one end with auxiliary air gaps 176, 178 between the upper and lower limbs 154, 158 and the central limb 156 across which the magnets 164, 166 develop fluxes opposite to those across the main air gaps 168, 170. A bucking coil 182 wound in opposition to and connected in series with the drive-coil 180 is located in the auxiliary air gaps and is mounted so as to be movable with the drive-coil so that although the coil 182 reduces the inductive effect of coil 180 the field across gaps 176, 178 causes it to produce a driving force assisting that of coil 180. Additional stationary, bucking coils may be mounted on the central limb beneath the coils 180, 182, Fig. 8 (not shown).

Filed: 1946-03-13
Abstract: 609,402. Control means for the wheel brakes of aircraft; steering. HELLINGS, G. M. March 13, 1946, No. 7813. [Class 4] In a control system for the wheel brakes of aircraft the total braking effort is determined by the rotary movement in the same sense of two foot pedals, while the distribution of the effort between port and starboard wheel brakes for steering on the ground is determined by the position of the rudder-bar or other flight-steering control. As shown, two pedals 13, 14 mounted for rotation about an axis 10 relatively to the rudder-bar 11, itself rotatable about an axis 12, serve to press a roller 16 downwardly against a link 17 operating fluid pressure master cylinders 20, 21 for the port and starboard wheel brakes respectively. The mean pressure in the cylinders 20, 21 is determined by the pressure on the pedals 13, 14, while the ratio of the pressures is determined by the position of the rudder-bar 11. A modification is described in which the steering control comprises swinging rudder links instead of a rudder bar and in which the position of the two pedals controlling the mean braking force varies as the swinging rudder links move so as always to conform to the natural position of the pilot's feet. The brake transmission may be mechanical or electrical, instead of hydraulic.
