Title: Braking device for vehicles
IPC: B60T13/66
Filed: 1928-11-22
Abstract: 300,994. Compagnie Internationale des Freins Automatiques. Nov. 22, 1927, [Convention date]. Fluid-pressure.-A braking device comprises a valve in the duct leading liquid under pressure to a brake cylinder, controlled by an automatic apparatus under the influence of the braking pressure, which closes this valve abruptly when the braking pressure reaches a certain valve. The yielding of the suspension springs of the vehicle are transmitted to a movable member of the automatic apparatus so that the operation thereof depends on the load on the vehicle. A valve 8a is maintained closed by a solenoid 8<d> supplied with current from a battery 12<c> by means of contacts 13<a>, 14<a> connected by a control handle 13. When the handle 13 is moved to bridge contacts 13<a>, 14<b> a, resistance 15 is included in the circuit which weakens the current and allows the valve 8<a> to open under the pressure in the reservoir 8 and pressure fluid passes to the brake cylinder 26 and a cylinder 5 of the automatic apparatus. A piston 6 in the cylinder 5 moves an arm 7 and a contact, bridge 7<a> to bridge contacts 10<a>, 10<b> short circuiting the resistance 15 and which causes the valve 8<a> to reclose. To obtain a strong braking action the handle 13 is moved to contact 14<c> to include the resistance 15 and also a resistance 16 in the circuit which is short-circuited by further movement of the piston 6 and bridging of contacts 10<a>, 11<b>. The current in the solenoid 8<d> may be annulled instead of reducing its strength by removing the resistances 15, 16 and providing sufficient spaces between the contacts 14<a>, 14<b>, 14<c> for the current to be broken when the handle 13 moves over them. In order to vary the. braking pressure according to the load the position of the dial 9 carrying the contacts 10<a>, 10<b> 11<b> is varied by an electromagnetic clutch. An arm 36b is provided connected to a rod 3 pressing upon an axle and carries an electromagnet 36 the magnetic circuit of which is completed through the dial 9 which is movable about its axis. The circuit through the windings of the magnet is broken by a centrifugal switch when the vehicle is moving so that the apparatus only operates when the vehicle is at rest. This switch comprises an elastic blade 18 carrying a weight 21 so that it is separated from a contact 23 by centrifugal force. It is mounted on an insulated ring 19 on the axle on which bears a brush 24 connected to the magnet winding. This switch may be actuated by the automatic door closing device or the engine controller. The dial is held in place by a friction shoe 20. Instead of varying the position of the dial 9 the strength of the return spring 6<k> of the piston 6 may be varied.

Title: Process for the preparation of coherent masses of the rare metals, and alloys and oxides thereof
IPC: C22B60/02
Filed: 1921-12-21
Abstract: Coherent masses are formed from powders of refractory metals such as zirconium, thorium, titanium, uranium, vanadium, tantalum, tungsten, and beryllium, or from their mixtures or oxides, by slowly heating one or more of the metals or their oxides or compounds in a high vacuum to expel volatilizable constituents and occluded gases and then heating them strongly to cause sintering.  The powder, loose or in compressed form, may be heated in a crucible or on a plate of molybdenum or tungsten closely surrounded by a coil through which is passed first direct or low-frequency alternating current, and afterwards high-frequency alternating current.  In some cases the metal may be formed in a porous state suitable for use as electrodes in electrolytic cells.  Alloys may be formed by starting with mixtures of a refractory metal with another refractory or other metal; and refractory materials such as zirconia suitable for making crucibles and other articles may be obtained by treating oxides.

Title: Improvements in, or relating to, air pistols and the like weapons
IPC: F41B11/647
Filed: 1946-11-21
Abstract: 619,108. Air guns. ACCLES & SHELVOKE, Ltd., and ARROWSMITH, J. B. Nov. 21, 1946, No. 34486. [Class 119] In an air gun of the type in which the compression chamber surrounds the barrel, a high compression is obtained by mounting a washer 11 of flexible material over a bush 9 on the working face 8 of the piston 7. This washer (Fig. 6) is formed with a boss 12 and a central hole 13 for forcing over ribs 10 on the bush 9. Around the periphery of the washer is a skirt 14 which bears on the inner face of the compression cylinder 1 as shown. Radial grooves 15 are cut in the face of the boss 12 of the washer 11. Internally at the breech end of the piston is formed an annular recess 18 in which is provided a rubber ring 19 held in position by a washer 20 and of greater diameter than the recess 18. A rubbing contact is thus effected on the outer wall of the barrel. When the piston 7 reaches the end of its travel the boss 12 of the flexible washer 11 impinges on the breech closure cap 2 and any air trapped in the pocket 16 is enabled to escape by way of the radial grooves in the face of the washer. The opening 3 in the breech closure cap 2 is sufficiently large to permit of the bush 9 projecting into it, further increasing the compression. A pad of flexible material 52 carried on a fixed plate 49 joined to the pivoted handle seals the breech closure cap when the gun is in the firing position. Cocking of the gun and unsealing of the breech closure cap are effected by grasping a lever 45 and swinging it downwards about its pivot 46 until it engages a bridge-piece 37a in the handle. Simultaneously, a tongue 47 on this lever forces a locking lever 43 out of engagement with a fixed pin 28 carried on side cheeks 23. A spring 48 previously held in position by the tongue 47 then continues the unlocking of lever 43 until this lever engages a stop 60. Further movement of lever 45 acts through a S-shaped bar 55 to compress the spring 22 until the ridge 7a in the piston is engaged by a spring-loaded sear 32. On returning the pivoted handle to the firing position, the locking lever 43 is forced over the pin 28 by the tongue 45 to hold the pad 52 firmly against the breech cap.

Abstract: 1,185,964. Transistor switching circuit. AMERICAN DISTRICT TELEGRAPH CO. 23 July, 1968 [21 Nov., 1967], No. 35048/68. Heading H3T. [Also in Division G4] A burglar alarm having a transistorized delaying circuit such that during a short time interval after switching on the protection, the premises can be left via a specified exit without setting off the alarm, the alarm incorporating test facilities. In Fig. 1 is shown the door contacts 12 which are in series with the other contacts or foil strips on various other doors, windows &c. throughout the premises. Across 12 are connected relay contacts S2 which when closed enable 12 to be opened without setting off the alarm. A three-position switch when in the OFF position has capacitor CD1 fully charged and the supply to the three transistors TRN 1, 2, 3, switched off. When switched to TEST, the alarm rings and TRN1 is switched on causing relay coil S86 to operate contacts S1, S2. Capacitor CD1 discharges through RX1 because of the voltage now across RX5. The switch is turned to ON and at a particular capacitor voltage TRN2 is switched on causing TRN3 and relay R150 to operate as well. With contact R1 now closed, TRN1 is switched off, S1, S2 open, switching off TRN2, TRN3 and leaving the system protected. From the above sequence it is seen that the door contacts 12 can be opened during the discharge of CD1, until TRN2 is switched on, because contacts S2 are closed. This time interval depends on the time constant of the discharge circuit CD1, RX1. In Fig. 2 (not shown) contacts R1 are replaced by a transistor. Fig. 3 shows an alternative arrangement with a similar sequence of operations. Switched to TEST and TRN2<SP>1</SP> is switched on, closing contact S1<SP>1</SP> and providing a shunt path for a part of the protected circuit via REC2, RX12. Switched to ON and when CD1 has discharged enough TRN1 is switched on, switching off TRN2<SP>1</SP>, opening S1<SP>1</SP> which switches off TRN1<SP>1</SP>, the alarm circuit now being fully operational.
