Title: Improvements in or relating to automatic condition regulators
IPC: G05B11/50
Filed: 1938-04-12
Abstract: 497,533. Fluid-pressure servomotorcontrol systems. SCHELLHASE, C. April 12, 1938, No. 11169. [Class 135] In an automatic condition regulator having a slide controlling the escape of air from a nozzle, the nozzle has a narrow rectangular aperture and is capable of rotation to vary the angular relation of the aperture to the operative edge of the slide. In a thermostat, the slide 20, pivoted at 19, has a right-angularly bent end 20a, Fig. 4, which controls escape of compressed air from a nozzle 21, and hence the pressure in a conduit 27, which in turn actuates a regulating valve to correct deviations from the desired temperature. The angular position of the slide is made dependent on the prevailing temperature by connecting an arm 18, secured to the slide, to the free end 15 of an arcuate bimetallic strip 5, the other end of which is carried by a support 7. The desired temperature is determined by the position of the support 7 in relation to a spindle 11. Turning the spindle 11 by means of its square end 1'2 moves the support 7 by means such as an eccentric, a pointer 13 indicating the setting on a graduated scale. The change in pressure in the conduit 27 for a given angular movement of the slide is governed by the orientation of the nozzle aperture 24, Fig. 4, being greatest when the longer side of the aperture is parallel to the operative edge DE of the slide. A U-shaped screen 31, surrounding the nozzle, directs the escaping air away from the bimetallic strip 5 and causes the room air in the vicinity to be sucked over the strip to improve the control. The aperture of the nozzle may be formed by a row of small holes.

Abstract: 946,258. Aircraft instruments. S. SMITH & SONS (ENGLAND) Ltd. April 17, 1962 [March 30, 1961], No. 11653/61. Heading B7W. An aircraft instrument comprises a compass ring 3 rotatable to show aircraft heading against a fixed datum 5, a pitch and roll indicating horizon line 16 visible through the compass ring, and a pair of radio beam deviation indices 30, 31, visible through the ring and movable respectively parallel and perpendicular to the datum direction of the horizon line in accordance with lateral and vertical deviation of the aircraft from a radio defined path, means being provided to move the indices 30, 31 out of view when not operated by radio beam receivers. In the exploded view of the Figure, the compass ring 3 is rotated about the instrument axis 4 by a servo 6 controlled conventionally by a gyro magnetic compass system 6b. A ring gear 9, assembled outside ring 3, has a marker 8 and is driven by a differential 12 having inputs from servo 6 and a manual " set heading " knob 14, so that marker 8 is driven over the compass ring by rotation of knob 14 to indicate a set heading on the ring, and the angular displacement of marker 8 from datum 5 indicates the departure of the actual from the set heading. A signal generator may be driven with ring gear 9 to provide a signal representing this departure, for use with an indicating device as in Specification 886,136. A further ring gear 28 having diametrically opposed markers 29, is assembled within ring 3 and driven by a servo 29<SP>1</SP> controlled by a directional receiver 29b in accordance with the relative bearing of a radio beacon, so that one marker 29 shows the bearing of the beacon on ring 3, and is aligned with datum 5 when the aircraft is headed towards the beacon. Behind the ring gears is located a roller blind type artificial horizon, the blind 19 having a division 16 between white and black areas 17, 18, and being driven over rollers by a servo 21 in response to pitch angle signals from a gyro vertical 22. The roller blind assembly, together with a transparent sheet 23, is rotated about axis 4 by servo 20 in response to roll signals from the gyro vertical 22. A marker 25 on sheet 23 indicates the angle of bank against a scale 26 on a fixed ring 27 assembled within ring 28. Ring 27 also bears marks at the ends of a horizontal diameter, providing a pitch datum for the roller blind. The indices 30, 31, are each carried in a fine wire 32, 33, traversed by twin lead screw assemblies 35, 37, driven by servos 34, 36, respectively, controlled by localiser and glide path receivers 34b, 36b. Relay means is provided so that when a servo 34, 36 is not connected to its receiver, a bias signal is applied to the servo to move the index out of view. Concentric circles 24 on sheet 23 assist in judging the displacement of the indices. Specifications 853,034 and 927,180 also are referred to.

Abstract: 766,128. Storing and transporting gases. MORRISON, W. L. April 22, 1954, No. 11685/54. Class 8(2) Transport of natural gas mostly methane from a well source 37 to a place of use, e.g. a burner 24 heating a steam generating boiler 25 is effected by compressing and liquefying in a condenser 11 cooled by a two stage refrigerating system A, B and feeding the liquefied gas through a valved duct 12 into a transportable insulated container 13 maintained at just above atmospheric pressure by a relief valve 18 which allows vapour from above the liquid in the container to pass to an engine 20 driving the transport vessel, e.g., a ship 14; any excess vapour being vented through said valve 18 to atmosphere. Accidental ignition of such wasted vapour is prevented by mixing it with sufficient inert gas, e.g. carbon dioxide from a reservoir 29 in a nozzle 27 open to atmosphere; the diluent gas feed duct 28 being controlled by a device 30 responsive to pressure in the vapour discharge duct 19. The reservoir 29 also supplies carbon-dioxide to the vapour space of the container 13 through a duct 33 when a valve 32 therein is opened by a device 31 responsive to a predetermined oxygen content of the vapour space. On reaching the destination the vapour passes through a land duct 21 to a refrigerating system 22 and to the burner 24. In a modification the vapour serves to cool a eutectic circulating in a cold chamber on board ship prior to being fed to the engine.

Filed: 1939-04-20
Abstract: 576,686. Remote control systems. POLLOPAS PATENTS, Ltd. (Oster, L. E. W. Montrose-). April 20, 1939, No. 11872. [Class 40 (i)] [Also in Group XXXVII] The transmitter and the receiver of a repeating system each comprise two synchronous machines-a motor driving an alternator through differential gearing-the two alternators being connected electrically so that movement of the differential housing of the transmitter causes the differential housing of the receiver to be moved in a similar manner. As shown in the Fig. the motors a1, b1 rotate at 1,500 r.p.m., movement of the housing 4 causing the speed of alternator a2 to increase or decrease and of alternator a3 to decrease or increase, depending upon the direction of the motion. The alternators b2 and b3, which are running at 1,500 r.p.m. will be drawn into synchronism with alternators a2 and a3 respectively, thus causing the housing 4<1> to rotate in a manner similar to housing 4. Since the alternators a2 and a3 rotate in the same direction the housings 4, 14 will have a tendency to do the same, but since the two gears mesh directly they will counter-act each other producing a state of equilibrium. In another arrangement, Fig. 1 (not shown), only one alternator is used at the transmitter and receiver. If movement in more than one plane is to be transmitted, a transmitter and receiver is necessary in each plane. A hydraulic differential device may be used instead of differential gearing for establishing equilibrium between the systems.
