Title: Improvements in and relating to arc extinguishing devices
IPC: H01T1/04
Filed: 1946-12-13
Abstract: 645,827. Protective arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 13, 1946, No. 36873. Convention date, Dec. 15, 1945. [Class 38 (iv)] [Also in Group XXXVII] In an arc extinguishing device the arc is initially established in one compartment and rapidly transferred, by a magnetic flux, to another compartment for extinguishment. As applied to a lightning arrester a central electrode 11 is arranged with insulating members 13, 14, 15 in concentric relation to a cylindrical electrode 12 having a finger 45 extending into a compartment 25 formed by members 13 and 14 to cause the are to be formed initially across the short gap 47. The arc current through a coil 39 around the outer electrode 12, and connected between this electrode and earth, provides an axial flux which rapidly moves the radial arc through an inclined slot (Fig. 2, not shown) in member 14 into a serpentine compartment 30 formed by concentric projections on spaced members 14 and 15, wherein the arc is extinguished without possibility of return to compartment 25. The upper compartment 30 may be vented to atmosphere through hole 38 and axial recess 37<SP>1</SP> in electrode 11. The opposed faces of members 13 and 14 are corrugated to increase the insulating surface area. A spark-gap 43 may byepass the coil 39. Specification 592,843 is referred to.

Title: Improvements in or relating to phenolic resins and to a process of making the same
IPC: C08G8/06
Filed: 1928-12-15
Abstract: 326,545. Wade, H., (Bakelite Corporation). Dec. 15, 1928. Phenol-aldehyde condensation products.-Non- reactive phenolic resins are prepared by heating a non-reactive phenol-methylene resin with furfural and a basic condensing agent for a time sufficient to convert the resin into a mass which is brittle when cold, but insufficient to destroy its non-reactive character. The initial resin may be made from phenol, cresol, or a mixture thereof, and formaldehyde, and may have incorporated with it another resin of still lower reactivity; for example, a cresol-formaldehyde or phenol-acetaldehyde resin may be added to an initial resin derived from phenol and formaldehyde, or a retarding agent such as rosin may be added thereto. In an example, the liquefied initial resin, to which stearic acid and hydrated lime are added, is maintained at a temperature of 130‹-150‹ C. for some time while stirring, furfural is then added, and the stirring is continued until a sample of the resin is brittle, when cold. The hydrated lime may be replaced wholly or in part by other basic condensing agents, for example, magnesia, or the hydroxides or carbonates of sodium or potassium. Moulding mixtures are prepared by incorporating the products with methylene-containing hardening agents and fillers. To lessen the time required for the final hardening, a small proportion of such hardening agent may also be added during the furfural treatment stage.

Title: Hand weapon
IPC: F42B5/08
Filed: 1967-08-14
Abstract: 1,202,901. Weapons. KAMSON RESEARCH Ltd. 14 Aug., 1967 [20 Oct.,1966]. No. 37249/67. Heading F3C. A weapon comprises a barrel 6 extending from a casing, the casing housing a two part breech block 54, 58 and a loading piston 118 which acts as part of an electrical firing circuit. The circuit also includes a contact strip 59 carried by and insulated from the lower breech block part 58, a compression spring member 62 which urges the lower breech block part to its breech closed position, and a contact brass bar 66 mounted on a contact block 68. The bar 66 co-operates with the positive terminal of a battery 92. The bar 66 may be held away from the spring member 62 by a rotatable member 64 which forms the operative part of a safety device 20. With the safety device 20 in its inoperative position, the spring loaded trigger 14 engages the contact block 68 through a toggle mechanism 82, 84 to urge the block 68 into engagement with the spring member 62 to complete the firing circuit when the trigger is urged into a first position. When the trigger 14 is urged into a second or more depressed position the part 82 of the toggle mechanism engages a lever of a bi-metallic switch 94 to complete a firing circuit through a lead 96 connected between the switch 94 and spring member 62. Current passing through the switch 94 heats the the bi-metallic contacts up and thus breaks the circuit until the contacts cool down again. Rapid firing of the weapon at predetermined time intervals is therefore effected. Cartridges 120 are fed to the chamber of the weapon from a magazine held in magazine receiver 100, the cartridges being urged down into the path of the loading piston 118 when the latter is in its retracted position. On the return stroke of the loading piston 118 the cartridge being fed engages a tapered surface on each of the breech block parts 54, 58 to force the parts away from each other against their spring loading so that the cartridge passes into the chamber of the weapon. The loading piston is retracted by the action of a gas piston (Fig. 6, not shown) on a handle 26 of the loading piston. A cartridge 120 comprises a propellant charge 122 contained within a steel sleeve which is closed by a nylon top cap 124 and a nylon or non-conductive material end cap 132. The firing terminals are built into the end cap 132 and connected to an igniter capsule within the charge 122. The projectile which issues from the weapon comprises the end cap and sleeve of the previously exploded cartridge and thus no extractor is required for the weapon.

Title: Remote control apparatus for sheet caliper control
Inventor: GOYETTE FRANCIS HENRY
IPC: D21F7/06
Filed: 1965-09-01
Abstract: A sheet caliper control device for paper-making machines, of the type having a series of nozzles on top of a chamber to direct air from the chamber against a roll-for example a calender roll-to cool those parts of the roll having too great a diameter and thus decrease the roll diameter thereat, has power operated means for actuating the valves of the nozzles independently.  The valves may be fluid pressure actuated (c.p. Fig. 4 shown in Division F2), the fluid supply for each valve being controlled by a solenoid valve actuated by a switch or alternatively a solenoid may be directly operative to open a clapper valve.

Abstract: 1,140,118. Injection moulding machines. MASCHINENFABRIK UND GIESSEREI NETSTAL A.G. 19 Aug., 1966 [19 Aug., 1965], No. 37334/66. Heading B5A. A mould member 4 is moved to a substantially closed position by pistons 13 and cylinders 14 and then, if there is no obstruction between the mould member 4 and a fixed mould member 2, an increased closing pressure is applied by a piston 6 and cylinder 20 through toggle mechanism 5. In operation, magnetic valves 10, 16 are first activated and in turn actuate control valves 9, 15 so that pressure liquid in the hydraulic system only acts on pistons 13. At this stage liquid is transferred from space 8a through valve 9 to space 8b. When the mould members come together a contact 17 is closed by a cam 18 and disconnects a magnetic valve 10, thereby allowing liquid to pass through valve 9 to cylinder 20. If there is an extraneous object between the mould members a time delay relay causes an alarm to operate.

A smoothing circuit comprises a cathode follower V 1 (or emitter follower) input supplying through a diode D a capacitor C which is also charged by a constant current input. If the input voltage falls the capacitor is partly discharged through the diode, the constant current obtained from a high voltage supply HT+ and resistance R1 also flowing through the diode. If the input voltage rises the cathode follower output voltage rises and the diode no longer shunts the capacitor, which charges at a rate determined by the constant current. Another cathode follower may follow the output and an amplifying stage may precede the whole circuit. The constant current may be obtained from another valve (Figs. 2 and 3, not shown).
