Title: Aircraft cabin air conditioning system
IPC: B64D13/04
Filed: 1945-09-18
Abstract: 612,319. Automatic control systems for air conditioning. GARRETT CORPORATION. Sept. 18, 1945, No. 24034. Convention date, Sept. 5, 1944. [Class 38 (iv)] [Also in Group X] An air conditioning system for an aircraft cabin 16 comprises an internal-combustion engine or other power source 10 driving a compressor 13 which takes in air through a duct 14 for delivery to the cabin via a duct 15 and cooler 19, an air outlet 25 including a turbine 26 which assists in driving the compressor, and associated with another outlet 28 direct to the outer atmosphere, with an aneroid 43 responsive to changes in the cabin air pressure to control valves 27, 29 in the outlet pipes so as to keep the pressure within a desired range. The engine throttle 37 is controlled by a cam 68 operated by a reversible motor 67 according to the position of a contact 76 affected by the air flow to the cabin through a venturi 80 so that the fuel supply is reduced when the air flow increases and vice versa. Temperature responsive means such as a thermostat 42 in the cabin or inlet duct is linked with a reversible motor 49 on shaft 55 of which cams 56, 57, 58 govern the actuation of dampers 18, 23, 32 in the inlet duct, a duct 21 in which cooler 19 is disposed and the intake duct 14 respectively. A rise in temperature results in damper 18 increasing the quantity of air byepassed through a duct 17 and a turbine 20 which is coupled with turbine 26, thus cooling the air and reducing the power required from engine 10. Meanwhile, shutters 23 have already opened to permit a fan 22 to draw cooling air through cooler 19. Similarly, a fall in temperature causes the shutters to close, damper 18 to open and eventually damper 32 to move towards its closed position, whereupon the reduction in air flow brings about an increase in the compressor speed with a rise in the air temperature. When the engine throttle is fully opened, closure of a switch 72 ensures that thermostat 42 is operative only within a range determined by the angular dimension of an insulated portion 63 of a disc 62 on shaft 55; if the shaft rotation is enough to cause a brush 65 to contact either a brush 64 or 66, energizing of an electromagnetic switch 47  opens the thermostatic switch and also reverses the motion of the shaft until insulator 63 again contacts brush 65. For winter use a heater 91 supplied with engine exhaust gases through a pipe 93 may heat the air duct at the point of entry into the cabin. A valve 94 controlling a byepass round the heater may be operated from shaft 55. The engine carburetter may be fed with cabin air after further compression in a supercharger 96 to which it is supplied by a duct 96<SP>1</SP>. Engine 10 may be utilized at sea level to drive a generator 97 from which the main engine starters may be energized.

Title: Improvements in or relating to information stores
IPC: G11C11/06
Filed: 1962-06-22
Abstract: 983,767. Magnetic storage devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 22, 1962 [June 27, 1961], No. 24125/62. Heading H3B. An information store comprises a matrix of magnetic storage cores K1-K9 having remanent properties, but not necessarily rectangular hysteresis characteristics, which are controlled by row conductors 5-7 and pairs of column conductors 11, 14-13, 16 in association with pairs of saturable cores 3, 4. The sense conductor common to the storage cores is not shown. Cores 3, 4 are normally saturated by current from sources 19, 20, and a pulse in a row conductor 5-7 normally divides equally between branches H1, H2 wound in opposite senses on a storage core so that the remanent state is unaffected. To store information in a core such as K2, a gate 17 or 18 is closed so that a column of cores 3 or 4 are desaturated. At the same time a pulse is applied to row conductor 5. As the desaturated core 3 or 4 in the row has a high impedance in its associated winding 1 or 2, the row conductor pulse passes mainly through one of the branches H1, H2 and switches the storage core.

Title: Turbines and like machines having adjustable guide blades
Inventor: MAGIN SIDNEY HENRY ALBERT
IPC: F01D17/16
Filed: 1952-10-03
Abstract: 737,472. Turbines ;axial-flow compressors. NAPIER & SON, Ltd., D. Sept. 28, 1953 [Oct. 3, 1952], No. 24894/52. Classes 110 (1) and 110 (3). In a turbine or compressor having a ring of guide blades adjustable about radial axes and lever arms each attached by one end to one of the adjustable blades, the other ends of the arms being connected to a common annular adjusting member so as to permit relative radial movement between the levers and the adjusting member, the adjusting movement of which is in the axial direction, the dimensions of the adjusting member are such that it is substantially more rigid in the axial than in the radial direction and is actuated by several similar servomotors disposed at intervals around it. The hot gases from an annular combustion chamber or several individual combustion chambers 11 pass through a ring of adjustable guide blades 12 to the turbine rotor blades 13. The combustion chambers 11 have a sliding fit in an annular member 16. The blades 12 are supported at their inner ends in the flange 19 of the annular member 16 by pivot spigots 24 and at their outer ends by pivot spigots 25 which turn in bearings 26 carried by the outer casing 27. Each of the spigots 24 has a lever arm 28 secured to its innermost end. The lever arms 28 which lie approximately in the circumferential direction when the blades 12 are set in the central position carry pins 30 which engage circumferential slots in an annular adjusting member 31 so that relative movement between the pins 30 and 31 is permitted in the radial and circumferential directions, but not in the axial direction. The adjusting member 31 comprises a hoop whose width a is substantially greater than its radial thickness b. Projections 32 on its rear edge are connected to the pistons 33 of servomotors 34 controlled by fluid supplied through pipes 35, 36 by a control valve. To avoid all of the axial thrust on the blades 12 being taken through the outer ends of the blades, compressed air from the compressor is led through the shaft 15 and ports 22, 23 to the rear of the annular member 16. The ring of blades 12 may include some fixed blades as described in Specification 737,473. The adjusting member 31 may be arranged outside the ring of guide blades instead of, as shown, inside this ring.

Title: An improved control system for textile machines
IPC: D01G31/00
Filed: 1957-08-07
Abstract: 862,056. Control of two motors. ADAMS, S. J. Aug. 7, 1957, No. 24955/57. Class 38 (3). [Also in Group IX] In a roving frame driven by a main motor and provided with a travelling cleaner or lint remover which blows a stream of air, a control system normally energizes the main and cleaner motors, simultaneously de-energizes these motors on detection of a slack or broken roving, is manually set successively to restart the main motor and then, only after predetermined time intervals, to render the main motor again responsive to slack roving detection and to re-establish the air stream when the roving will not be harmed thereby, i.e. when the roving resumes its travel. The diagram represents normal conditions in a control circuit with both motors energized. A manually-operated shipper rod SR controls switches 41 and 49 between three positions, viz. "off" in which 41 is open and 49 closed, " jog " in which both switches are closed, and " run," in which 41 is closed and 49 open. When a roving breaks or becomes too slack, a drop-wire switch 2 closes a signal lamp 17 and relay R1 circuit to operate a switch 7, which closes a holding circuit for the lamp and relay, and a switch 8 which opens the energizing circuits of relays R2 and R5 and so stops the main motor M and the cleaner motor CM. The rod SR is moved to "off" and (a) de-energizes transformer T which de-energizes relay R1, which will then only be re-energized when transformer T is energized AND switch 2 closed, and (b) de-energizes tune-delay relay R3 which opens a switch 44 in the primary circuit of transformer T, and the switch 44 cannot then be closed again except on closure of switch 41 and subject to a delay, e.g. 8-10 seconds, determined by preset mechanism TD3. The rod SR is moved to " jog " to energize starting relay R2 for motor M and the relay R3 to prepare the detector circuit for closure by delayed switch 44; relay R4 is also energized (with R2) and closes motor CM circuit after a preset delay by mechanism TD4. If the delays do not permit adjustments to be completed, rod SR is returned to " off " and then to " jog " whereby the timing recommences. Finally, rod SR is moved to " run," the relay being held through a switch 53, and, when switch 44 closes, the detector circuit becomes operative. A limit switch 5 is opened and closed during and by reversals of the transversely-moving carriage to prevent unwarranted operation of the detector circuit.
