Patent GB-132806-A (GB)
IPC: F42C1/04
Abstract: 132,806. Taylor, J. W. Sept. 17, 1919. Projectile fuses.-Relates to delay-action percussion fuses of the kind in which, on impact, a striker is released and driven backwards by a spring after a delay depending on the resistance encountered. According to the invention, a shock-absorbing pad is interposed between the striker and the impact end of the shell so that when impact takes place, the striker cannot rebound from the part against which it abuts and operate prematurely. In the fuse shown, the spring-urged striker 9 has a lateral pin 12 normally engaging in an oblique extension 13<a> of a longitudinal slot 13 in a fixed tube 8, Fig. 2. The pin is held in this position bv engagement with a slot 15 in the lower end of a sleeve 16 which is slidably mounted on the tube 8, under the action of a spring 19, and is guided by a pin and slot 18, 17. A pad 20 of lead or other non-resilient substance is placed as shown, for the purpose stated above. When impact occurs, the sleeve 16 moves forward, releasing the pin 12. The inertia of the firing-pin keeps the spring 10 under compression until retardation ceases, whereupon the spring drives the firing-pin into the primer 6.

Patent GB-611665-A (GB)
Title: Improvements in the production of cellulose esters
IPC: C08B3/16
Filed: 1946-05-03
Abstract: A partially hydrolysed cellulose ester of a lower aliphatic acid is subjected to the washing or leaching action of hot distilled water to render it more reactive, and is then converted into a mixed ester of cellulose by reacting it with a long chain aliphatic acid esterifying agent such as the acid chloride.  The long chain esterifying agent may contain 12-20 carbon atoms.  The cellulose ester may be treated with 24-60 volumes of distilled water at 80-100 DEG  C.  A single treatment or several treatments with distilled water may be given. Following the activation treatment, the hydrolysed lower aliphatic ester of cellulose is dried and it is then ready for the further esterification.  It may be dissolved in pyridine at a temperature of 50 DEG  to 70 DEG  C. and may then be heated with the acid chloride of a long chain aliphatic acid at 85 DEG  to 100 DEG  C.  The product may be isolated by diluting the pyridine solution with acetone, methyl acetate, or dioxane, and then streaming the solution into water, whereby the cellulose ester is precipitated.  The production of cellulose acetatelaurates is described.  These may contain 0.6 to 0.8 free hydroxyl groups, 0.5 to 0.8 lauryl groups, and 1.4 to 1.75 acetyl groups per glucose residue.  The products may be moulded at 165 DEG  to 200 DEG  C.  The freshly precipitated cellulose acetate-laurate may be washed with hydrochloric acid, dried, ground, extracted with ether, and then stabilized by heating under pressure with very dilute sulphuric acid.  It may then be washed with aqueous alcohol and then with water.

Title: Improvements in or relating to electrical controllers
IPC: H02P1/02
Filed: 1956-05-02
Abstract: 824,779. Control of A.C. motors; controllers. IGRANIC ELECTRIC CO. Ltd. May 2, 1956 [May 31, 1955], No. 13534/56. Class 38 (3). [Also in Group XXXV] An electric motor 12 driving a press 10 is started by closing push-button 54 to energize relay 52 which has a self-maintaining contact 52b. Upon closure of switch 34, relay 18 is energized to connect the motor to the supplylines and cause a contactor 24 to pick-up whereby contactor 22 is energized. To effect energization of solenoid 16, which releases the brake and clutches the motor to the press, both " run " buttons 36, 37, must be depressed. Such operation de-energizes contactor 24 but coil 22d remains energized through contact 22a so that current flows through the coil 20f of contactor 20. Contacts 20a, 20b, then complete a circuit to solenoid 16. The opening of contact 20e interrupts the circuit of coil 52a but contacts 52b, 52c are not immediately opened due to the time-delay feature of the relay 52. After the punch and die have closed so that a hand may not be inserted between them, limit switch 30 closes to complete a maintaining circuit for coil 20f. The " run " buttons 36, 37, may now be released and contactor 24 re-energized. A short time later in the cycle of press operation, limit switch 28 opens to de-energize coil 22d so that contact 22c normally closes to re-establish the maintaining circuit for coil 52a before contacts 52b can open. Somewhat later the limit switch 28 re-closes, but coil 22d is not energized. Near the end of the cycle of press operation, limit switch 30 opens to de-energize contactor 20 and stop the press when the ram reaches the top of its stroke, the motor continuing to operate whilst the press is stopped. The operator cannot cause the press to run continually by keeping the " run " buttons depressed since the opening of limit switch 28 will prevent the establishment of a circuit for the coil 20f. If the relay 22 fails to pick-up or drop-out the press will be prevented from starting or will stop, even if the operator does not release the " run " buttons during a press stroke. The failure of contactor 24 to pick-up or drop-out will cause the press to stop at the end of its stroke or prevent the initiation of a new cycle of operation. If the " run " buttons are fastened down, a new cycle of press operation cannot be started. The failure of contactor 20 to pick-up prevents energization of the solenoid 16 and starting of the press. If contactor 20 fails to drop-out it is impossible to re-energize coil 20f even though the " run " buttons are operated properly. The contactor 18 provides novoltage protection.

When the chamber 1 is empty the float 38 falls and opens the low-pressure valve 13, at the same time opening the valve 15 through the lever 25 to allow the liquid in the chamber 2 to be discharged. The low and high pressure valves are operated independently by the sleeves 36 and rods 28 respectively. The sleeves 36 may be dispensed with. As applied to the cooling water of the engine, the liquid inlet pipe 18 is connected to the lower part of the radiator, the outlet passage 19 to the cylinder jacket, and the low-pressure chamber 6 by a pipe 46 to the top of the radiator, and by a pipe 47 to the induction pipe, so that both the chamber 6 and the top of the radiator are subject to engine suction. The high-pressure chamber 4 is connected bv a pipe 49 to a point slightly above the level of the top of the radiator and open to the atmosphere. The rate of circulation is controlled by a cock 48 on the pipe 46. The chambers 1, 2 may have at the top auxiliary low-pressure valves controlling a small auxiliary low-pressure opening to allow the liquid to rise in the chambers after the main low-pressure valves have been closed.
