Title: Improvements in or relating to aircraft wheel brakes
IPC: B64C25/48
Filed: 1932-02-23
Abstract: 397,497. Aircraft wheel-braking system. INDIA RUBBER, GUTTAPERCHA, & TELEGRAPH WORKS CO., Ltd., Aldwych, House, Aldwych, London, TARRIS, F. J., c/o India Rubber, Gutta Percha, & Telegraph Works Co., Silvertown, London. Feb. 23, 1932, Nos. 5420 and 11117. [Class 4.] For operating aircraft wheel brakes a main ontrol applies pressure equally to the brakes on the two sides of the machine and two auxiliary devices associated with the rudder bar act to increase the pressure on either of the brakes while reducing the pressure on the other. The Figure shows a cross-section of one of the auxiliary devices. Pressure fluid is supplied through a pipe 14 when the brakes are to be applied and the pressure forces back a piston 24 against a light spring 31 until two toggle links 47, 48 are straightened out. The fluid also passes through a valve 36 normally held open by a piston 19 under the pressure of a spring 30 strong enough to resist the maximum working pressure and reaches the corresponding brake mechanism through a pipe 40. The centre pivot 54 of the toggle links is stopped when slightly below the line joining the end pivots 49, 46 so that the toggle readily collapses when the pressure is released, but when the rudder bar 56 is moved it engages a surface 50 below the pivot 49 so that the toggle is prevented from collapsing as the piston 24 is forced inwards to increase the pressure in the conduit 14. Simultaneously the piston 19 is withdrawn by a lever 43, the valve 36 closes to isolate the corresponding brake from the increasing pressure which is transmitted freely through the opposite auxiliary control device, and the piston 19 as it continues to retreat forms an expansion space for the pressure fluid of its corresponding brake. Should the brakes be applied while the rudder bar is put over to correct a cross wind, they are applied equally because the toggle links 47, 48 engaged by the rudder bar remain in their collapsed position until the rudder bar is restored to its central position. The pipes 14 are branched from a common conduit connected to a camoperated pressure device similar to that described in Specification 355,818, [Group XXXIV]. Specification 364,674 also is referred to.

Title: Improvements in or relating to Telephone Systems.
IPC: H04M17/02
Filed: 1918-03-28
Abstract: 124,583. Automatic Telenhone Manufacturing Co., and Ray. A. J. March 28, 1918. Automatic exchange systems; coin-freed and metering systems.-Relates to measured service devices of the kind described in Specifications 10286/11, [Class 100 (i), Feeding and delivering webs &c.], and 687/12 in which a reversal of the line current brought about by the response of the called subscriber renders the calling telephone in. operative for talking purposes until the measured service device has been operated by the calling subscriber to record or pay for the call. According the present invention, the calling telephone is prevented from being again rendered inoperative by further changes in the direction of the line current due to the replacement and removal of the receiver at the called station. To this end, a second set of springs 30, 31, 32 controls a short circuit around the operating-winding 11, the arrangement being such that the springs are closed upon the response of the called subscriber, but the short-circuit is completed by the operation of the device to record or pay for the call. The arrangement shown operates as follows :-When the subscriber removes his receiver to make a call, a circuit is closed through the receiver 2, transmitter 1, and winding 11, whereby an extension 14 on the armature 13 is moved over a lug 15 on an arm 16 into the position shown in the Figure. When the called subscriber replies, the fine current is reversed and the extension 14 moves the arm 16 to the right, whereby the springs 18, 27, 28 short circuit the transmitter 1. and shunt the receiver 2 by a resistance 29, and at the same time a member 23, pivoted at 22, falls so that a part 25 comes behind the spring 30. The calling subscriber then operates his register to record the call, or inserts a coin in the shoot 21, whereby the arm 16 is depressed against the action of a spring 19 and the lug 15 disengaged from the extension 14. The arm 16 is thus moved to the left and the springs 18, 27, 28 render the telephone operative, whereas the springs 30, 31, 32 are held by the part 25, so that the winding 11 is short-circuited over springs 31, 30, 32, 26, 18, and is therefore unaffected by further reversals of the line current. When the calling subscriber replaces his receiver, a circuit is closed through winding 10 and springs 30, 31, whereby the armature 13 is restored to its normal position and the member 23 raised to release the springs 30, 31, 32. In a modification, the springs 30, 31, 32 are controlled directly by the armature 13, which is retained against the core of winding 11, after this is short-circuited, by the residual magnetism of the core. The Provisional Specification describes a further modification in which the winding 11 is not shortcircuited, the armature when once attracted to the core being retained in spite of reversal of the line current.

A pump, or motor, has working chambers defined by a housing 1 and a bladed main-rotor 3 meshing with auxiliary rotors 6, the chambers being connected to inlet and outlet conduits 16, 17 in an input, or output, shaft 2 by bores 20, 21, respectively. The rotors are synchronized by gear-wheels 22, 23. A second embodiment, Fig. 3, differs mainly in that the main rotor 30 is movable axially relative to its shaft 29 and a sleeve 38 thereon so as to vary the output, movement in one direction being effected by fluid-pressure applied to a rod 46 through a bore 47 and in the other direction by fluidpressure acting on the rotor through a bore 48. Fluid enters the working chambers through a conduit 40 and bores in the main rotor and leaves the chambers through passages 43 in the sleeve. In each embodiment the main-rotor blades have an epicycloidal profile may be axially straight or helical. The machine may be adapted to operate as an I. C. engine. (For figures see next page)

Title: Improvements in reduction gear devices
IPC: H03J1/14
Filed: 1940-04-03
Abstract: 539,289. Epicyclic gearing. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and PAYNE, G. April 3, 1940, No. 6048. [Classes 80 (i) and 80 (ii)] [Also in Group XXXVI] Consists in an epicyc ic redaction gear in which, after a movement of pre-determined extent through the reduction gear, the reduction gear is put out of action and a direct drive brought in. A coarse and fine adjustment is thus provided by the gear which is applicable to the adjusting of tuning elements of radio apparatus. The change from coarse to fine adjustment is effected by reversing the movement of the driving member. A driving shaft ds carries a disc dk which engages planets dd<11> mounted on pins pi which rigidly connect spiders sm<1>, sm<11> of which sm<1> rotates over the driving shaft and sm<11> is fixed to the driven shaft dn. Also mounted on each pin is a pair of washers wa<1>, wa<11> so positioned as to grip tightly between them the inner edge ie of a flat ring cr. One of each pair of washers is attached to a planet wheel. The ring cr is slotted at as to form three springy tongues to which, normally, grip the wall wl of the housing to hold the ring against rotation. The free ends of the tongues are pivoted to links lm which, at their other ends are slotted to engage the pins pi. While the ring cr is held by the tongues the gear acts as a reduction gear, but after the driven shaft and therefore the spider have been rotated a predetermined amount, depending on the length of the slots sl, the links are picked up by the pins and exert a pull on the tongues thereby releasing the ring cr and producing a direct drive. Toothed gears may replace the friction gears and, instead of springy tongues, radial bolts propelled into spring-gripping position by helical springs may be used.

A rotary filter 70 is fitted to prevent soiling. The magnetic coupling is mounted on polyamide bearings. Water may be circulated instead of air and the outside pipe coils may be surrounded by a wet felt jacket to increase the cooling. The inside coils may be brought into heat exchange relationship with the cooling water system of the vehicle's engine.
