Title: Improved mechanical and automatic means for locking and releasing railway carriage doors
IPC: E05B65/36
Filed: 1919-12-24
Abstract: 159,693. O'Donnell, J. Dec. 24, 1919. Pneumatically-operated fastenings; turn-bolt door fastenings. - A railway-carriage door lock, operated by releasing or applying the vacuum or pressure brakes, comprises a cylinder communicating with the main train pipe or compressedair reservoir controlling the brake apparatus, and a rod movable with a piston in the cylinder, which rod is adapted to engage in a recess in the end of a latch pivoted on the door, so as to look it. The latch may also be secured in addition by a manually-operated spring-controlled sliding bolt adapted to engage with it. The cylinder i, located in the door jamb h, contains a hollow piston k, carrying a rod l which passes through a stuffing- box j<1>. A small pipe o leads through a ball-valve p from the rear end to the front of the cylinder, the valve serving, in the case of a pressure brake, to relieve the pressure in the rear portion of the cylinder, or, in a vacuum system, enabling a vacuum to be established behind the piston. A spring s acting on the pistonrod tends to hold it in the outer position, as shown, where its end can engage in a recess b<3> in the end of the rotary latch b, pivoted on the carriage-door, and thus lock the latch when it is turned by means of its handle c into the horizontal position. The auxiliary locking-device consists of a spring-pressed hand bolt d, adapted to engage in a recess b' in the side of the latch. The surfaces leading to each of the recesses b<3>, b<1> are bevelled. When the brakes are of the pressure type, the action of applying the brakes causes compressed air to be admitted to the cylinder i through a pipe n, thereby effecting the withdrawal of the piston-rod from the recess b<3> in the latch. With vacuum brakes, this unlocking action occurs when, on the application of the brakes, air is admitted through the pipe n, destroying the vacuum only in the front end of the cylinder.

Title: Improvements in or relating to the treatment of wool, feathers, hair and the like for cleaning and protecting purposes

Title: Improved remote controlled impulse senders
IPC: H04M1/274
Filed: 1949-12-23
Abstract: 664,908. Impulse transmitters; automatic exchange systems. AUTOPHONE, Ltd., and ROSENFELDER, R. I. Dec. 23, 1949, No. 32965/49. Class 40 (iv). In a remote-controlled impulse transmitter capable of emitting a plurality of impulse series in response to a single controlling action, impulsing is initiated by means of a plurality of switching means having self-propelling contact members, such as the wipers of a uniselector, switch-over means being provided for rendering at least one of said switching means ineffective during one part and effective during another part of the operation. In the embodiment shown, depression of one of a number of keys (not shown), each corresponding to a multi-digit number, applies earth to a corresponding terminal PB and thereby operates an associated marking relay, say I, and a common starting relay A which completes a circuit for stepping a uniselector US under the control of a self-interrupting magnet D and a timing relay R. Commoned contacts are arranged in groups, one group for each digit to be sent, distributed over banks BI, BII, BIII of the uniselector US and are separated by non-commoned contacts of which one in each group, corresponding to the number to be sent, has marking potential applied to it by the marking relay I. Each time the first wiper f passes a commoned contact an impulsing relay J is momentarily energized to send an impulse to the exchange over terminals a2, b2, the calling subscriber's set being connected to terminals al, b1. When the wiper f reaches the first marked contact, it completes a circuit for a slow-releasing terminating relay S which disconnects the impulsing relay J and holds until the wiper f leaves the first group of commoned contacts. The second impulse train is transmitted similarly, the second wiper. b taking over when the first wiper f leaves its contact bank BI at the end of the first half of the first rotation of the uniselector US. At the end of the first complete rotation, a switch-over relay O operates over wiper a, extending the commoning to bank B IV and transferring earth from the first wiper f to the third wiper e which now controls the transmission of the third impulse train. After terminating the impulsing, the relay S holds over wiper e or a, so that when wiper d reaches contact O of bank B V at the end of the second rotation it breaks the holding circuits of relays I, A and O, which release, together with S, returning the apparatus to its original condition. If a two-digit number is to be transmitted by the apparatus shown, which has a capacity of three digits, the contact 49 of bank B II is the third contact marked, so that the apparatus is released after one rotation of the uniselector US. If the calling subscriber's line includes an amplifier, it is prevented from becoming unbalanced when the starting relay A short-circuits the line by a resistance or impedance network W. The operation of relay S at the end of impulsing removes the shortcircuit so that conversation can begin at once without waiting for the uniselector US to come to rest.

A junction rectifier or transistor comprises a semi-conductor member 1, Figs. 1 and 2, having a collector electrode 2 on one surface and a number of concentric base and emitter electrodes 3-8 on the opposite surface, the alternate concentric electrodes 3, 5, 7 forming an emitter group while the remaining electrodes 4, 6, 8 function as a base group. The semiconductor member may comprise germanium, silicon or a binary compound such as aluminium phosphide, aluminium antimonide or gallium arsenide. In use, the various emitter-base systems may be connected in parallel to form a common emitter and base connection, or they may operate at different control potentials. The rectifier or transistor may be produced by the use of a graphite mould, Fig. 4, comprising upper and lower parts 9, 10 having appropriate recesses into which are fitted pre-shaped metal electrodes and the semi-conductor member. The mould 11, Fig. 6, is mounted in a non- magnetic frame 16 and is housed within a gas filled or evacuated furnace housing 16 on a heated plate 12. During heat treatment the components contained in the mould are subjected to pressure by an iron weight 14 and a spring 15, the pressure being reduced in the course of the alloying process by energising a magnet system comprising a core 17, the weight 14 and an energising coil 18.

In a pan mixer having a mixing blade assembly which rotates about a vertical axis and also makes an orbital movement about the axis of the pan, both movements are effected by an hydraulic motor or motors. As shown in Fig. 1, an hydraulic motor 13 has a shaft 18 driving a rotating casing 16 in which is journalled a shaft 21 carrying a mixing blade assembly 22, 23 ; rotation of the casing 16 causes rotation of the mixing blade assembly 22, 23 by reaction of the planet pinion 20 with the fixed sun gear 15. The casing 16 may carry auxiliary mixing blades as at 24. In another embodiment, Fig. 2, the hydraulic motor 13a is mounted on the casing and drives directly the planet gear 20a and the mixing blade assembly 22, 23, being supplied with pressure fluid by pipes 27, 28 and passages in the fixed shaft 18a which connect with pipes 29, 30 by means of circumferential grooves in the shaft (see also Fig. 3, not shown). In a further embodiment (see Fig. 4, not shown), the mixing blade assembly is mounted on a rotatable spider and both are rotated independently by separate hydraulic motors driving directly or through reduction gearing. A control valve may vary the speed of the motor or motors; pressure fluid may be obtained from supply mains or from a pump.
