Title: An improved combined clockwork and direct action percussion fuze
IPC: F42C9/04
Filed: 1938-06-09
Abstract: 502,933. Projectile fuzes. JUNGHANS. H., and JUNGHANS AKT.-GES., GEB. June 9,1938, No. 17159. (Class 9 (i)] A combined clockwork, and direct-action percussion fuze of the kind in which the striking pin is divided into a number of separate portions, the terminal member, which pierces the detonator, passing through the hub of the balance wheel, is characterized in that the direct-impact and ignition members of the striking pin are, in the safe position, supported by separate devices which ensure barrel and muzzle safety, and the ignition member is slender to reduce friction of the balance wheel. In the construction shown, the striking pin comprises three members d<1>, d<2>, d<3>, the lower end of the impact member d' being guided in a sleeve d<21> surrounding the upper end of the intermediate transmission member d<3>. The lower end of the ignition member d<3>, which passes through the hub ! l of the balance wheel k, is of reduced diameter, with collar d<31> at the top end. In the safe position, the sleeve d<21> rests upon centrifugal members f forming the barrel-safety device, and the collar d<31> rests upon a pivoted, toothed member g, Fig. 2, which engages with a pinion h of the clockwork train, and forms the muzzle-safety device. Upon discharge of the projectile, the members f are prevented from moving outwardly by the inertia of the sleeve d<21>, until acceleration ceases, when the members d d' of the striking pin are released. When the clockwork commences to function, rotation of the pinion h withdraws the pivoted member g from beneath the collar d<31> of the ignition member.d<3>, which latter is thereby freed and the arming of the fuze completed.

Filed: 1976-04-23
Abstract: 1486867 Porous sheets of thermoplastic polymer CHLORIDE GROUP Ltd 23 April 1976 [25 April 1975] 17269/75 Heading C3C A porous sheet is made by forming a plastic mass of a thermoplastic polymer, particulate removable filler and an extractable organic solvent or plasticizer, forming the mixture into a sheet, removing the solvent or plasticizer by extraction with a fluorinated hydrocarbon which is liquid at ambient temperature and has a b.p. above 45 C. under atmospheric pressure, treating the extracted sheet to remove the fluorinated hydrocarbon and to remove the removable filler. In the examples mixtures of polyvinyl chloride, isophorone (3,3,5-trimethyl)cyclohexene - 2 - one - 1 and kerosone with particles of starch, ammonium sulphate or anhydrous sodium sulphate, and optionally glycerine were formed at elevated temperature and high shear, and the resultant powders were extruded to form sheets which were then passed through a bath of dichloromonofluoro-difluoromonochloroethane to leach out the isophorone/kerosene mixture, and then the sheet was passed into hot water to evaporate off the fluorinated hydrocarbon and the water-soluble fillers, and when starch is used as filler the sheet is then passed into boiling water to swell the starch (thereby producing rupturing of walls encapsulating the starch) and the starch is then removed from the sheet in a hydrolysis medium which is aqueous sulphuric acid. The polyvinyl chloride may be plasticized with a chlorosulphonated polyethylene of a nitrile rubber, which are not leached out during the above process.

Title: Improvements in or relating to fluid pressure-regulating valves
IPC: F01M5/00
Filed: 1940-12-10
Abstract: 546,453. Valves. DANIELSEN, J. W., [Representative of DANIELSEN, P. J.], SEIFFERT, D. H., BUTT, A. G., and HALL, L. F. Dec. 10, 1940, No. 17492. [Class 135] A pressure-regulating valve, particularly adapted for use in a lubricant circulating system, is adapted to open under the action of fluid pressure and is associated with a viscosity-responsive means whereby the pressure, up to a certain maximum, at which it will open automatically increases with increase in viscosity of the fluid and vice versa and above that maximum will open irrespective of the viscosity of the oil. In the form shown in the Figure a valve A loaded by a spring co-operates with a removable seat D<SP>1</SP> to control a byepass conduit connecting the delivery and suction sides of a pump. A ported tubular spindle A<SP>2</SP> on the valve member slidably engages on a cylindrical member B provided with a head B<SP>1</SP> held against the end of a piston C by a spring J. Fluid from the conduit Y passes through an aperture A<SP>1</SP> in the valve member protected by a strainer G into a chamber L<SP>1</SP> from which it escapes through a capillary passage in the member B, ports C<SP>1</SP> in the piston C, and a passage F<SP>1</SP> to the conduit F. The pressure in the chamber L<SP>1</SP> varies with variations in the viscosity of the fluid. This pressure is transmitted through ports A3 into a bellows L connected to the valve member and the piston C and so varies the loading pressure on the back of the valve. On the pressure in conduit Y becoming excessive the valve and piston move as a unit to permit free flow of the oil. In a modification the piston C is fixed and excessive pressure lifts the head B<SP>1</SP> out of contact with the piston and so relieves the pressure within the bellows to permit the valve to open. In another modification a tubular extension of the valve member slides on a tubular member integral with a detachable cover. In this form the capillary tube is secured to a ported boss on the cover.

Abstract: 1,091,167. Continuously winding-up stock. MASCHINENFABRIK HERBORN ZWEIGNIEDERLASSUNG DER BERKENHOFF & DREBES A.G. April 26, 1965 [April 27, 1964], No. 17494/65. Heading D1J. An apparatus, Fig. 1, for winding continuous stock comprises co-axial reels 1, 2, each reel having a rim on which are stock catchers 14 and stock clamps 13, there being a stock laying carriage 6 for traversing the stock onto one reel and, when said reel is full, for carrying the stock over to the empty reel where the stock is caught and clamped at 14, 13 and then traversed onto the empty reel by the carriage 6. The stock catchers can each be upper and lower portions 24, 23, Fig. 6 (not shown) defining a mouth 26 to catch the stock; and the clamps 13 are coil springs 13, the pitch of the turns of the springs 13 being approximately parallel to the direction of the stock as it passes from the carriage 6 to the catchers 14. Before transfer of the stock from reel 1 to reel 2 the carriage 6 is moved to the extreme left-hand setting shown. A guide roller 9 is then swung upwardly and the carriage 6 is moved to the right, the stock being pulled across the raised roller 9 so as to prevent further traverse of stock onto the reel 1. When the carriage 6 has passed a central swivelling arm 7, Fig. 3 (not shown) the arm 7 swings across the path of the stock and forces it to a position between the two reels 1, 2, where it is caught by the catchers 14 on each reel. The clamps 13 on reel 2 then grip the stock and the carriage 6 traverses the stock onto reel 2. The carriage 6 is constructed on a double carriage consisting of a main carriage 30, Fig. 7 (not shown) which slides on the guides 5 and supports further guides 31 for a carriage 32. During the winding-on operation, only the main carriage 30 performs a reciprocating motion. When the stock is to be transferred from one reel to another the carriage 32 is moved.

Title: Improvements in or relating to the operation of brakes on trailer vehicles
IPC: B60T11/10
Filed: 1957-06-03
Abstract: 836,924. Trailer vehicle brakes. HENRY, H. P. June 12, 1958 [June 3, 1957], No. 17605/57. Class 103 (1). In a trailer brake operating device comprising a liquid pressure master cylinder operable by relative approach movement of coupled tractor and trailer vehicles to apply brakes on the trailer vehicle, the master cylinder is arranged to serve also as a damping device for damping the relative approach of the vehicles. In the embodiment illustrated, the trailer brake operating device 10 is mounted on the forward end of a tow-bar 11 forming a part of a trailer vehicle. A rod 12 projecting forwardly from the body 13 of the device 10 carries at its front end one part of a trailer coupling, shown as a ball-and-socket coupling of which the socket 14 is mounted on the rod 12 and the ball 15 is mounted on a horizontal transverse bar forming part of a tractor vehicle. In operation, when the trailer vehicle tends to overrun the tractor vehicle, the master cylinder piston 32 moves rearwardly in the reduced portion 24 of the bore 18. Liquid is forced through the conduit 45 to apply the brakes and a disc valve 52 is provided in the master cylinder outlet to ensure that the flow of liquid from the master cylinder is retarded, and the master cylinder thus acts also as a dashpot to regulate the rate of relative approach movement of the vehicle. When the towing pull is restored, the rod 12 tends to move forwardly and the movement is damped by the movement of a piston 39 in a chamber 27, this piston forcing liquid from a chamber 27 into a reservoir 19 through a passage 42. Under the pressures generated by normal running, the pressure build up in the master cylinder is insufficient to open a valve 35 in the master cylinder piston 32, but if the tractor vehicle is backed towards the trailer, thus applying the brakes on the latter, a pressure is built up sufficient to open this valve and allow escape of liquid from the master cylinder through passages 31 and 43 to the reservoir. The piston 32 moves rearwardly until the pin 53 contacts the valve 35 and holds it away from its seat to release the trailer brakes and allow the vehicles to be backed together. Alternative embodiments are disclosed in the Complete and Provisional Specifications. Specification 714,400 is referred to.
