Abstract: 737,094. Turning-gear. BARRETT, W. W. H. June 22,1953 [June 27,1952], No. 16277/52. Class 7(5). In an engine starter comprising a driving friction-wheel 14, Fig. 2, and an idle frictionwheel 13, and wherein the latter is mounted on a lever 4 adapted to be pivoted about the axis of wheel 14 by the torque thereof acting frictionally on the lever 4 to engage a driven friction wheel, for example the engine fly-wheel 20, when the wheel 14 is rotated by a starter motor 1, the lever 4 and a fork 11, Fig. 1 are pivotable about the axis of wheel 14 and an axis parallel thereto, respectively, whilst the idle wheel 13 is supported on the fork for rotation about an axis parallel to the pivotal axis of the fork. A bush 3, Fig. 2, for the starter motor shaft 2 has the lever 4 pivoted thereon, which lever has a pin 5 engaged in a slot 7 of a bracket 6 that supports the fork 11, Fig. 1, the open ends thereof accommodating a further pin 12, upon which is journalled the wheel 13. The driving wheel 14 Fig. 2, is slidably keyed onto shaft 2, the latter incorporating a friction clutch comprising a collar 15, between which and one end of the roller 14 is located a spring 16, and a fibre disc 17 between the other end of roller 14 and lever 4. Wheels 13 and 14 are urged into constant engagement by a spring 18, Fig. 1. When the motor 1 is started the friction between roller 14 and lever 4 causes the latter to pivot and bring roller 13 into contact with the engine flywheel 20 to drive the latter. In a modification, the friction between rollers 13 and 14 is increased by making roller 13 of soft rubber and providing a number of holes in its periphery or knurling the roller 14 ; the clutch may be dispensed with. In a further modification, the clutch comprises a spring-loaded disc bearing on one end face of the idler roller. In any of the above embodiments the stops represented by the ends of the slot in the bracket may be adjustable and the withdrawal of the idle roller may be effected by spring means or gravitationally.

Filed: 1973-04-06
Abstract: 1464717 Fluid-pressure servomotor systems CAV Ltd 1 April 1974 [6 April 1973] 16485/73 Heading G3P  In I.C. engine fuel injection pumping apparatus of the kind having an injection pump 11, 12 with a fluid operated timing control member 39 and a metering valve 33 comprising a centrifugally controlled axially movable member for determining the amount of fuel supplied to the pump during the filling strokes of the latter, the axial position of the member 41 varies the loading of a spring 61, Fig. 2, which acts on a valve-member 60, the latter controlling an orifice 63 through which fluidpressure from a passage 36 flows to a conduit 45 for use in controlling the position of the timing control member 39. The effort of the spring 61 is supplemented by pressure in the conduit 45 and a restrictor 64 allows a throttled flow of fuel to a drain. In Fig. 3 (not shown) the valve-member 60 is in the form of an annular piston (60a) slidably surrounding a reduced diameter end of the member 41. As described in U.K. Specification 1461573 the pressure established in the passage 36 is controlled by the metering valve 33 and a valve 52 to vary in dependence on the square of the pump speed. Since the position of the metering valve 33 controls the amount of fuel supplied to the pumping chamber 11, the pressure established in the conduit 45 and supplied to timing control member is a function of the square of the speed and also the amount of fuel delivered. The engine speed can be set by a manually controlled cam 56.

Filed: 1965-04-20
Abstract: 1,094,933. Producing self-crimping polypropylene filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 4, 1966 [April 20, 1965], No. 16543/65. Heading B5B. Self-crimping composite polypropylene filaments are produced by conjugate melt spinning of two propylene polymers having the same intrinsic viscosity, but different molecular weight distributions, and subsequently drawing and/or relaxing the tension in the filaments. The " dispersion coefficient " of at least one component must be at least 6À5 and the dispersion coefficients of the polymers may differ by at least 0À5. The component polymers may have a viscosity of at least 1À0. The unrelaxed spun filaments may be drawn 2-4 times their original length and the drawing may be effected by means of a snubbing surface heated to not over 100 C. The drawn filaments may be heat treated on the draw roll which is maintained at a temperature of up to 100 C. The crimped filaments may be stabilized by heat treatment at 100.. 140 C. The " dispersion coefficient ", which is an expression of the molecular weight distribution of a propylene polymer is defined as the ratio of the weight average molecular weight to the number average molecular weight of the polymer, these values being determined by light scattering and membrane osmometry techniques described in detail in the Specification. The intrinsic viscosities of the polymer are measured in decalin solution at 135 C., the units of intrinsic viscosity being decilitres/gram.

Title: Flight control system
IPC: B64D45/00
Filed: 1957-05-24
Abstract: 818,436. Automatic control systems for aircraft. SPERRY RAND CORPORATION. May 24, 1957 [May 29, 1956], No. 16556/57. Class 38 (4). In an aircraft control system, when the aircraft approaches a stall condition, a servomotor operating the elevators is controlled by two signals, one dependent on the setting of a manual controller and the other, produced by a stall detector, continuously increasing in a sense to move the elevators downwardly. In Fig. 1 deviations in the pitch attitude of an aircraft are detected by a gyro-vertical 13 signals from an inductive pickoff 17 of which are applied through a phase-sensitive amplifier 18 to control a servo-motor 20 correcting the deviations by adjustment of elevators 12. Follow-up signals are provided by an inductive device 21 operated by servomotor 20. The pitch attitude to be maintained by the system is set manually by operation of knobs 29 which adjust through differential gearing 33 a potentiometer 24 applying further signals to amplifier 18. If the aircraft tends to approach a condition of stall, one or other of stall detectors 69 or 70, according to the position of switch 71, energizes relays 87, 51 to start a motor 40 and couple it through an electromagnetic clutch 47 to a second input shaft of differential gear 33 so that potentiometer 24 is adjusted to move the aircraft away from the stall attitude. When detector 69 is selected by switch 71, approaching stall conditions are detected by air pressure on wing- mounted vanes 72, 73 operating switches 74, 75. One switch operates nearer the stall condition than the other. Both switches must close to start motor 40 which then continues to run until both switches open again. When detector 70 is selected by switch 71, approaching stall conditions are detected by a cylinder 94 which projects from the aircraft and has longitudinal slots so that it rotates to a position corresponding to the angle of attack of the aircraft and thereby adjusts potentiometers 97, 98 so that when the angle of attack is greater than that determined by a knob 103, setting potentiometers 99, 100, there is sufficient output from the bridge circuit formed by the potentiometers to start motor 40. A lamp 65 operated by relay 51 gives warning that motor 40 is operating. Worm gears 37 and 43 provide irreversible couplings between differential gear 33 and knobs 29 and motor 40 respectively. In a modification, Fig. 2 (not shown), operation of relay 51 also energizes an electromagnetic clutch to brake knobs 29, and thereby give further warning, when motor 40 is operating. Specification 717,704, [Group XX], is referred to.
