IPC: F41A19/05
Filed: 1917-08-25
Abstract: 128,656. Birmingham Small Arms Co., and Norman, G. Aug. 25, 1917. Machine guns.-Relates to means for synchronizing the firing of automatic machine guns with the movements of an external member, e.g. the propeller of an aeroplane so that discharge will only take place when a projectile can pass between the propeller blades. According to the invention, the gun is provided with a breech-bolt actuating- member having a limited axial movement relatively to the breech-bolt, and a striker slidably mounted on the breech-bolt and also on the actuating-member, the striker being cocked and the striker spring energized by the actuating-member, and the striker being released by mechanism driven from the external member, with the motion of which the firing of the gun is to be synchronized. Fig. 1 shows the invention applied to a Lewis gun, the trigger of which is under the control of the engine of an aeroplane. The striker pin 1 is spring-mounted in jaws 5 in the breech-bolt actuating-member 6 so as to be moved into cocking position, with the vertically sliding sear 7 in engagement with the bent 12, when the member 6, on moving rearwards relatively to the breechbolt 2, engages a collar 20. The striker spring 3 is cocked between the jaws 5 and a collar 4 during the return movement of the member 6. The. sear has a lower extension 13 with a shoulder 18 engaging behind a shoulder 6<a> on the member 6 to form an abutment when the striker is released. The member 6 carries a release slide 23 having rear inclines 31 which raise the sear on to a surface 19, to permit the extension 13 on the sear to travel in a slot in the rear end of the member 6 when this moves rearwards. When opening the breech by hand, the cocking-lever 24 first travels in a slot 27 relatively to the member 6 to move the release slide 23 to the rear against the action of a spring 32, and thereby raise the sear. The trigger 15, pivoted at 36, carries a spring plunger 39 engaging a recess 46 in the underside of the member 6 only when the breech is closed and locked, in which position an extension 40 on the trigger plunger 39 is in the path of the trigger rod 42 reciprocated from the engine or a cam on the propeller shaft. The sear is then lifted by a projection 14 on the trigger to release the striker only when the rod 42 moves to the left and the plunger 39 is in the raised position shown, corresponding to a closed and locked breech.

Title: The decolourisation of cellulose derivatives
IPC: C08B3/22
Filed: 1930-04-23
Abstract: The discolouration of cellulose esters and ethers due to the presence of metal compounds, notably iron, is reduced without variation of their solubility characteristics by treatment with a polybasic aliphatic acid or with a salt of such acid, for example, oxalic, citric, and tartaric acids, and their mono- and di-sodium and potassium salts.  The cellulose derivative may be treated in the solid state or in solution, and, after treatment, is separated from the decolouring agent, and is then washed and dried.  In examples, cellulose acetate in solid form is treated at temperatures which may range from room temperature to 100 DEG  C. with a dilute aqueous solution of oxalic acid; a solution of cellulose acetate in acetone is treated with a dilute aqueous solution of oxalic acid, and subsequently is precipitated.  The treatment is particularly applicable to cellulose acetate and other organic derivatives of cellulose; but it may be applied to inorganic derivatives such as cellulose nitrate.

Title: Improvements in or relating to telecommunication exchange systems
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04M15/04
Filed: 1948-05-07
Abstract: 653,411. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. May 7, 1948, No. 12603. [Class 40 (iv)] In a long distance telecommunication system (especially international system) in which calls to certain exchanges may be set up over alternative routes, the route taken is recorded or indicated to an operator in response to signals reverted from the tandem exchanges. The system is similar to that described in Specification 645,303, in which each tandem exchange reverts an " international " proceedto-send signal and the final exchange a " national " proceed-to-send signal. In one embodiment note is taken of the outgoing direction from the originating exchange and the " international " proceed-to-send signals are counted as they are received from the different tandem exchanges and the routing schemes so arranged that for each number of such signals received when a given distant exchange is reached by a call starting out in a specified direction there can be only one route taken. In another embodiment each proceed-to-send signal is accompanied by the identity of the exchange reverting it. In the first embodiment a register-controller, Fig. 3, transmits D.C. impulses from equipment DCI to set the outgoing selector (not shown), which thereupon hunts in the group of outlets in the preferred direction. If all outlets in that direction are busy 11th step springs operate bringing up SR momentarily to step the switch DSM and signal to the equipment DCI that the next preferred group is to be tried and so on. When a free outlet is seized and the international proceedto-send signal is received by equipment VFR, voice frequency transmitting equipment VFT transmits the wanted exchange code at the same time as VFR operates PR to step the switch RSM. Switch RSM is thus stepped as the call reaches each tandem exchange. When the wanted exchange is reached a " national " proceed-to-send signal initiates transmission of the remaining digits and operates Z to light an appropriate route lamp at the operator's position over banks of DSM and RSM. In the second embodiment, Fig. 4 (not shown), the identities of the tandem exchanges are registered on relay sets which bring up appropriate route lamps at the operator's position. Specification 358,043 is referred to.
