Title: Landing gear system
IPC: B64C25/28
Filed: 1965-06-08
Abstract: 1,104,652. Retractable aircraft undercarriages. IN - FLIGHT DEVICES CORPORATION 8 June, 1965 [8 June, 1964], No. 24253/65. Headings B7G and B7W. Aircraft landing gear is retracted or extended by electric, hydraulic or pneumatic power under pilot control, and a control system is provided to extend the gear automatically, or prevent the pilot retracting it, under certain conditions. As described the gear is operated by an electric motor having " UP " and " DOWN " windings connected to a pilot's control switch 10, the supply to which, from a busbar 22, may be cut off by a first switch 3 operated by a pressure switch α which is closed when the airspeed is below 1À1 Vs (Vs being the stalling speed), or below a predetermined altitude. Hence the pilot cannot retract the gear under these conditions. A second switch 4, operating below 1À5 Vs, or some higher altitude, by a pressure switch #, by-passes the pilot's control to energize the " DOWN " winding, automatically lowering the gear, if one of two other sensing devices γ and # is actuated. The device γ is actuated on reduced engine power, being sensitive to manifold pressure or throttle position or alternatively to thrust vector angle of a direct lift engine; as described there are two devices γ, one for each engine. The device # is actuated when the flaps are lowered below a certain angle, or when propellers are put into fine pitch. Switches actuated by the devices γ and # are also in series with the first switch 3, so that the gear can only be raised above 1À1 Vs when the flaps are up and the engine power above a predetermined level. The control system may be over-ridden to allow normal pilot operation, and a warning light 14 and horn 15 are then operated. Further lights are provided to indicate (a) when the flaps are down, (b) when the landing gear is down, (c) when the landing gear is up, and (d) when the pilot's control has selected gear retraction and the control system is holding it down. The test switch 13 when closed, should cause all the warning lights and the horn to operate when the aircraft is at rest on the ground and the system is operative.

Title: Improvements relating to the stop motions of winding machines for textile threads
IPC: B65H63/036
Filed: 1932-09-03
Abstract: 407,005. Stop - motions for threadwinding machines. STUBBS, W. L., 15, Oxford Road, LATHAM, H. E., 15, Norfolk Street, (Executors of STUBBS, J. H.), and STUBBS, Ltd., J., Ancoats, all in Manchester. Sept. 3, 1932, No. 24588. [Class 120 (ii).] In stop-motion apparatus for a machine for winding textile threads, a member 11, 13, associated with the thread traverse guide 3 and reciprocated therewith, is practically in equipoise and is supported by the thread x being wound in a path normally free of contact with a knock-off motion lever 15, this latter lever being pivoted so that an end thereof will be moved in a vertical plane with a wedging action by the members 11, 13 when such member leaves its normal path on breakage of the thread. On breakage of the thread, which is normally guided by a grooved wheel 12 of vulcanized fibre, the arm 13 falls so that it will engage and raise one end of the lever 15 thereby depressing a lever 14 which withdraws a latch 19 from beneath a projection 18 on the clutch-operating arm 8 this latter moving under spring action to disengage the clutch. On piecing the thread the operator moves the arm 8 manually to re-start the machine and the levers 14, 15 and latch 19 regain their original positions under the action of a spring 16.

Title: Hydraulic controls for change speed gears
IPC: F16H61/02
Filed: 1959-07-17
Abstract: 891,042. Change-speed control. CATERPILLAR TRACTOR CO. July 17, 1959 [March 18, 1959], No. 24592/59. Class 80 (2). [Also in Group XXXIV] In a vehicle transmission having speed ratio trains and forward and reverse trains selectable by hydraulically applied brakes, a selector valve 18 controls the supply of fluid from an enginedriven pump 14 to brake cylinders 1, 2, 3 for first, second and third gears, and a valve 20 controls the supply to brake cylinders F, R for forward and reverse, and the arrangement is such that the forward and reverse brakes can only be applied after the application of one of the gear ratio brakes. A valve 28 controls the rate at which the pressure rises in a selected brake cylinder. The transmission, which is described in Specification 891,041, is of the planetary type and a main clutch is dispensed with. Valves 18, 20 are manually operated and, as shown are in their neutral positions. The pump supplies liquid through a line 30, the pressure in which is determined by the valve 28 which is loaded by a spring 44 compressed by a piston 43 subject to pressure derived from the line 30 through a restricted orifice 32 and passages 38 in a valve 26, and through a restricted orifice 41 in a floating check valve spool 39. Valve 18 is moved successively to the right to open the speed ratio brakes to pressure, and a valve 22 is interconnected with the valve 18 and prevents flow of liquid from a line 33 to the valve 20 when the valve 18 is in its neutral position; and thus the forward and reverse brakes can only be applied after the selection of a gear ratio brake. If valves 18, 20 are actuated simultaneously the restricted orifice 32 maintains a pressure differential sufficient to ensure that the gear ratio brake is applied first. The rate of application of the brakes is controlled, since when valve 18 is operated to open a brake line to the line 30 the pressure in line 30 drops while the brake line is being filled and the valves 28, 26 move to the left. Piston 43 is moved to the right by the spring 44 and the expelled liquid moves the check valve 39 to the left, uncovering an exhaust line 40 to give rapid exhaust. When the brake line is filled valve 28 is opened by liquid entering a cavity in its spool through orifices 34, and the loading on the valve is gradually increased to increase the pressure in the brake cylinders, by pressure liquid admitted to the piston 43 through the restrictions 38, 41.

Abstract: 1490213 Metal vapour lamps GENERAL ELECTRIC CO Ltd 19 May 1975 [4 June 1974] 24672/74 Heading H1D In a high pressure Hg discharge lamp with refractory light transmitting discharge envelope, e.g. SiO 2  or Al 2 O 3 , the wall-stabilized arc running in Hg vapour plus a small quantity of rare gas, together with Na halide and T1 halides emitting in the blue-green, can be made to emit light nearer to black body radiation by increasing the Hg vapour pressure to 6-20 atmospheres at operating temperature. The fill may include 20 torr of Ar at ambient temperature plus Na and T1 iodides and Hg. The limits for Hg pressure lamp power and length depend on the material properties of the discharge envelope and the supply voltage. The use of the halides of Na and Tl also improves the luminous efficiency at the high Hg pressure.

Abstract: 259,574. Siemens - Schuckertwerke Ges., Oct. 6, 1925, [Convention date]. Loaded cables.-Cables having a constant distributed self-inductance provided by a band or wire of magnetic material wound thereon, have the magnetic material wound on the conductor in the form of a corrugated band or wire to prevent reduction of permeability consequent upon tensile stresses. The smooth band or wire used for wrapping purposes is first passed through a fluting or corrugating device immediately prior to being wound on the conductor. After wrapping the whole may be passed through a limitative nipple to smooth out the corrugations slightly. Instead of the corrugated band a profiled band, e.g. one bent to U-shape, may be utilized.

Title: Improvements in Static Convertor Control Systems
Inventor: AINSWORTH JOHN DESMOND
IPC: H02J3/36
Filed: 1966-06-03
Abstract: 1,192,174. Converting; HVDC power transmission. ENGLISH ELECTRIC CO. Ltd. 1 June, 1967 [3 June, 1966], No. 24746/66. Heading H2F. In a converting system (such as a HVDC transmission link) in which a control signal is compared with a reference signal so as to determine the firing angle of controlled rectifiers, a rate limiting circuit is included to determine the maximum rate at which the firing angle can reduce towards zero so as to reduce the tendency for the D.C. output voltage to overshoot in response to sudden changes in operating conditions. Fig. 2 shows a polyphase rectifier 1, supplied by A.C. 3 and feeding current Id via inductor 6 to a HVDC transmission link. The current Id is monitored by D.C. current transformer 12 and compared in an operational amplifier 13 with a reference voltage selected by switch 15. The output of amplifier 13 is fed to a control pulse generator 9 feeding the mercury pool rectifiers or thyristors in converter 1. Starting arrangements.-The converter (not shown at the remote end of the D.C. transmission line is initially arranged to be operative only as an inverter. Switch 15 is set to position B so that amplifier 13 will provide an output to control circuit 9 so that converter 1 will attempt to operate in full inversion, giving zero D.C. line voltage. When switch 15 is set to position A, the rate limiting circuit 16 ensures that the input to control circuit 9 changes sufficiently slowly so that converter 1 gradually provides its full positive output and avoids overshoot due to the inductor 6 and capacitance of the transmission link. The firing angle and hence the output current is adjustable by potentiometer 14. Alternatively, the system may be controlled in dependence on D.C. power or A.C. frequency Rate limiting circuits.-Fig. 4 shows a suitable rate limiting circuit 16 in which resistors R6, R7 and diode D2 arrange two different output rates depending on the magnitude of the positive input voltage V1. Fig. 3 (not shown) relate to an alternative rate-limiting circuit comprising a capacitor charged by the forward or reverse resistance of a series diode during positive and negative inputs respectively. Series operation of converters.-Figs. 6, 7 (not shown), relate to the operation of two converter bridges in series, each bridge being by-passed by a valve when its grid-pulse isolating switches are open. The system is started by closing a switch feeding an R.C. network which thus provides a pulse of predetermined voltage-time product to an integrator feeding the control circuit 9.

Mechanical lapping may be used to remove the first part of the substrate 1. In a modification the substrate (1), Figs 6-9 (not shown), and the epitaxial regions (5) are both p-type, but a 2-5 Á thick n-type layer (2) is epitaxially deposited on the substrate (1) prior to formation of the mask and the regions (5). The layer (2) is eventually removed in an additional etching step after removal of the substrate (1). The pn junction between the substrate (1) and the layer (2) may be reverse biased during etching of the substrate (1).

If the projectile is accidentally dropped from a sufficiently great height that the blocking bolt 21 sets partially back and releases the blocking bodies 19, and the blocking sleeve also sets partially back to the position shown in Fig. 6, the blocking bodies 19 become clamped between the wall of the recess 31 and the blocking bolt 21 so that further retraction of the bolt 21 to arm the fuze is prevented even if the projectile is fired from a weapon. In a normal firing situation, the blocking bolt 21 sets completely back upon firing the projectile and releases the blocking bodies 19 which subsequently lock the blocking sleeve 16 in a completely retracted position, Fig. 5, whence the fuze is armed.
