Title: Aircraft Cabin Pressure Control System
IPC: B64D13/02
Filed: 1966-08-25
Abstract: 1,162,412. Automatic cabin pressure control. GARRETT CORP. Aug. 25, 1966 [Sept. 13, 1965], No.38237/66. Heading G3R. Signals, dependent in magnitude and sense on deviation of aircraft cabin pressure from a datum, control separate circuits to operate an A. C. motor at a corresponding speed in the appropriate sense to correct the deviation by adjustment of a damper controlling air outlet from the cabin. In Fig. 2, deviations of pressure in a pressurized cabin, from a value selected by the pilot, are detected by a unit 11 the electrical output of which is effective to correct deviations by controlling an A. C. motor 43 adjusting a shaped damper in an exhaust outlet of the cabin. According to the sense of deviation, a D. C. signal of one polarity or the other is applied through a line 69 or 71 to cause operation of the motor in one direction or the other. A transistor circuit 73 or 75 is thus controlled so that a blocking oscillator 81 or 81<1> operates to render a silicon controlled rectifier 83 or 83<1> conductive thereby causing the motor to run in the appropriate direction. Feedback circuits 87, 87<1> ensure that, for small pressure deviations, discrete groups of pulses are produced by the blocking oscillators, whereas for larger deviations the blocking oscillators operate continuously. Stabilizing rate feedback from a tachometer alternator 45 driven by motor 43 is demodulated at 59 and delayed at 61 before being combined with the output of unit 11. This feedback is also applied in A. C. form between a modulator 63 and a demodulator 67 in the control system. The stabilizing feedbacks may alternatively be derived from a resistance-condenser circuit having a suitable time constant, which integrates the pulses from both blocking oscillators. A switch 51, closed by the landing gear on landing, applies such a signal to the control system that the damper is opened to its limit. A further switch (not shown) disables the control system if the damper is operated manually.

Title: Improvements in or relating to the treatment of fibre assemblies with fluids
IPC: D06B5/04
Filed: 1962-10-10
Abstract: 988,734. Treating textile fibres with fluids. UNISEARCH Ltd., M. CHAIKIN, and A. SAMSON. Oct. 10, 1962 [Oct. 18, 1961], No. 38311/62. Heading D1L. In a method of treating a mass of loose fibres with a fluid e.g. wool scouring, washing, carbonising and neutralising, or dyeing, the fibres are compressed in a layer and the fluid is applied thereto by means of jets. As shown, raw wool is scoured or similarly treated by being fed between an endless belt 4 of flexible netting or mesh and a drum 3 having a periphery covered by wire mesh. The path so defined by drum and belt lies in part, below the surface of the treating fluid 2 in a tank 1. Treating fluid is fed from the tank by a pump 7 to jets 5, inside the drum and to jets 6 beneath the drum, the jets being so directed as to cause the ejected fluid to impinge upon the layer of fibres. The fibres are removed from the drum by a beater 12 and pass between mangle rollers 13 and 15 to a conveyer 16 which carries them away. A swing- ably mounted roller 8 tensions the belt 4 and so causes the layer of wool to be compressed. Specifications 573,042 and 683,137 are referred to.

Abstract: 1466962 Arbors E D HOUGEN 22 Feb 1974 [26 Feb 1973] 39190/76 Divided out of 1466961 Heading B3C [Also in Division B5] An arbor for an annular hole cutter comprises a shank member 32 having a forward end for supporting a cup-shaped annular cutter 14 which cuts a circular groove through a thick workpiece and forms a round slug within the cutter, the shank having a central bore 34, a pilot member 124 axially slidable in the bore and having a drill point 126 and a shoulder 128 adjacent to, but spaced axially rearward from, said drill point 126 wherein the pilot member is held in an axially forward position by a spring 70 to project the drill point forwardly of the cutting teeth 58 of the cutter 14, and is characterized in that a yieldably resisting retraction means, e.g. a spring and ball detent 136, 138, resists retraction of the pilot member within the bore 34 until the retraction force exceeds a value in excess of that required to cause the drill point to cut a pilot hole in the workpiece and thereafter permits axial retraction of the pilot member at a force substantially less than said value. In operation as the arbor is advanced towards the workpiece the drill point does not cut a hole under the influence of the spring 70 only. When a shoulder 134 engages the detent ball 136 an axial force is generated to produce cutting by a drill point. When the shoulder 128 engages the workpiece a higher force is generated to overcome the spring detent so that further feed of the arbor continues with a reduced axial force on the pilot member and no further drilling takes place by the drill point 126.

Title: Electrically-heated bimetallic strips
IPC: H01H61/04
Filed: 1974-10-29
Abstract: 1489566 Temperature responsive actuating device AB ELECTRONIC COMPONENTS Ltd 29 Oct 1974 [20 Aug 1973] 39316/73 Heading G1D [Also in Division H1] A laminated bi-metallic strip comprises three layers only, of which the outer layers are homogeneous electrically conductive layers, while the central layer is electrically insulating and has a thickness and thermal conductivity such that heat generated in one of the outer layers is readily transferred to the other outer layer. The coefficients of thermal expansion and thicknesses of the strip layers are such that the curvature of the strip changes with strip temperature. A thermal switch may incorporate the strip which strip is mounted on a base, there being provided means for making electrical connections with one of the outer layers which constitutes a heating element, and contact means arranged to be controlled by changes in the position of a portion of the strip 6 relative to the base. The length of the electrically conductive path through the heating element may be extended by one or more slits 4 which extend substantially parallel to the strip axis. In one embodiment, Fig. 1, the upper conducting layer forms the heating element, contact thereto being made via rivets 2, 3, rivet 3 electrically contacting both electrically conducting layers of the strip 6. Heating causes the strip 6 to curl upwards so as to break the contact 10. In a further embodiment, Fig. 2, the strip 14 is provided with a slot 17 so that the strip is U- shaped, the slot 17 continuing in the lower electrically conducting layer only so as to electrically isolate two legs 15, 16 of this layer. One leg 16 of this lower layer forms the heating element. When both legs 15, 16 experience the same temperature, contact between button 19 on leg 15 and a vertically adjustable button 24 mounted on base 18 is made. Heating of leg 16 via rivets 21, 22 causes downward curling of the leg 16, the contact 19 therefore moving upwards to break a conductive path between tags 25, 27. The heating element layer may be of copper nickel alloy, the other electrically conducting layer being of an aluminium alloy. The insulating layer may be of glass fibre mat impregnated with epoxy resin. The switch may be incorporated in a flasher unit.

Title: Improvements in clutches
IPC: H02N13/00
Filed: 1956-12-28
Abstract: 843,950. Friction clutches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 28, 1956 [Dec. 30, 1955], No. 39529/56. Class 80 (2). [Also in Group XXXV] An electrostatically engaged clutch comprises a first clutch member made from a conducting material, a second clutch member made from a semi-conducting material, and means for applying an electrical potential difference between the two members to engage them with each other, a liquid dielectric being disposed between the two clutch members. The clutch shown is similar to that of Specification 843,949, comprising a pulley 13 supporting on insulating sleeves 17 a metal ring 15 to which is secured one end 27 of a stainless steel band 26, connected at its other end to the ring by a spring 28 which biases it to engage lightly with the outer surface 25 of a ring 24 of semi-conducting material mounted upon a hub 12 fast with a shaft 11. To clutch the pulley 13 and shaft 11 together, a switch 23 is closed to apply the potential of a battery 22 through a brush 19 to the ring 15 and the stainless steel band 26, and simultaneously through a brush 21 to the hub 12. According to the invention, a liquid lubricant is disposed between the stainless steel band 26 and the semi-conducting ring 24. This lubricant may be silicone oil, or for use at high temperatures, may be melted methyl methacrylate. Lubricant is supplied by rotating the hub 12 and the ring 24 of semiconducting material slowly, while applying the dielectric generously to the surface 25. The surface 25 is then wiped off with a clean tissue. The film of lubricant may be maintained by a mohair wiper 31 which is first soaked in the dielectric and then squeezed out. When running with no potential difference applied through the switch 23, a torque-speed curve, Fig. 4 (not shown), shows a peak for torque at a relatively low revolutionary speed, the position at which this peak occurs being adjusted by making a number of holes 29 in the stainless steel band 26.
