Title: Improvements in or relating to a method for making caseless cartridges from smokeless powder
Inventor: O'MARA JOHN JOSEPH
IPC: F42B5/188
Filed: 1969-08-12
Abstract: 1,244,231. Moulding smokeless powders. HERCULES Inc. 12 Aug., 1969, No. 40369/69. Heading B5A. [Also in Division F3] Caseless cartridges are made from smokeless powder by (a) wetting smokeless powder granules with a solution containing a solvent for the powder and a non-aqueous carrier liquid which is miscible with the solvent for the powder but is not itself a solvent for the powder; (b) compressing the wet powder granules, and (c) drying the compressed material to form a cartridge. The solution preferably comprises 15-65 wt. per cent of one or more of acetone, methyl ethyl ketone, isopropyl methyl ketone, diethyl ketone, propyl methylketone, or isobutyl methyl ketone as solvent and 85-35 wt. per cent of one or more of methanol, propanol, isopropanol, butanol, or isobutanol as non- aqueous carrier liquid. The smokeless powder is preferably covered with the solvent for 5 seconds to 2 minutes and is pressed at a pressure of from 500-3000 p.s.i. The smokeless powder may be of single, double or triple base type formulation.

Abstract: 1,191,503. Control of stepping motors. GERBER SCIENTIFIC INSTRUMENT CO. 5 Sept., 1967 [17 April, 1967], No. 40443/67. Heading H2J. A pen carriage 10 is driven by stepping motors 22, 24, the motor 22 having its output shaft 26 coupled with lead screw 14 by gears 28, 30. The motor 24 is coupled with shaft 26 by gears 34, 36, and requires a smaller number of steps than the motor 22 to produce one revolution of its respective output shaft. The gears 34, 36 are related so that each motor tends to drive the shaft 26 at the same speed. Drivers 38, 40 for the motors receive pulses from controller 20 which compares signals representing the actual position of the pen carriage with command position signals, whereby the carriage is moved to the commanded end point, the motors 22, 24 each undergoing the same number of steps during a given period. Signals appearing on line 46 determine the direction in which the motors are stepped. During low speed operation, the motor 24 provides detenting action to locate the driven part accurately with little overshoot or vibration. For high-speed operation, the torque of the motor 24 decreases, and the motor 22 contributes mainly to the drive as the stepping rate increases. In a modification, the motors are mounted on the same shaft but are supplied at different pulse rates, whereby the motors are excited to operate at the same speed.

A piston comprises a body 14 of circular crosssection and a single resilient sealing member 18 having a first wall portion 56 located at the periphery of the body and including at least one flexible flange 56A for co-operation with the inner wall of the cylinder and a second wall portion which extends radially inward from the first portion in engagement with a radiallyextending face of the body and includes cushioning means 58 for cushioning the piston at the end of its stroke. The member 18 which may be of rubber, is moulded on or otherwise secured to the body so as to embrace its edges and sides. The cylinder-engaging surface of the member 18 may be concave or cupped to provide sealing edges 62, 64 or only a single sealing area may be provided at one side of the body. The cushioning means 58 are in the form of spaced bosses on circular raised portions on the radial walls of the member 18. The members 14, 18 may be mounted on a reduced portion of the piston-rod 16 and secured by a bolt 54; additional cushioning members 50, 52 for cooperation with the recessed ends 36, 38 of the cylinder may also be mounted on the piston-rod.

Abstract: 1,236,522. Position encoders. McGRAW EDISON CO. 14 Aug., 1969, No. 40692/69. Heading G4H. A position encoder includes two movable discs 20, 21 (Fig. 1) with transparent or perforated and opaque sections, lamps 27, 28 being sequentially lit so that the two sets of coded outputs from a photo-cell assembly 48, 48a, 48b, 48c, represent the positions of the discs. As described the photo-cell are connected in series with capacitors C1-C4 which are in the feedback circuit of a Colpitts oscillator. The capacitors which are normally open circuited have binary weighted capacitances so that a different oscillation frequency is obtained for each combination of photo-cell outputs. As described lamp 27 is illuminated after a delay determined by circuit 76 when a voltage of a first polarity is applied to telephone lines 12a, 12b by an interrogator 15 so that the position of disc 20 is sensed. During the delay a reference frequency is obtained from the oscillator. When a voltage of the opposite polarity is applied lamp 28 is illuminated and the disc 21 is sensed. Disc 21 is rotated with the member the position of which is to be measured, disc 20 being moved one step for each revolution of disc 21.

Abstract: 989,796. Actuation of switches; controllers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 8, 1963 [Oct. 29, 1962], No. 40823/62. Heading H2B. An actuating shaft 1 for the switches 16, 17 of an on-load tap changer is rotated by an electric motor 5, and the arrangement includes a flywheel 8 on the motor shaft, a brake 6 and a brake timing cam 7 on a shaft 3 driven by the motor and flywheel, which cam controls the brake to stop the motor 5 and actuating shaft 1 if the power supply to the motor is interrupted before sufficient time has elapsed to ensure a flywheel charge which will complete a tapchanging operation. A pivoted arm is movable electromagnetically to make a switch in the motor circuit, the arm bearing a roller cooperating with segments on the timing cam 7 such that when the arm falls through a gap between the segments, the motor supply is interrupted and the brake engages (Fig. 2, not shown). In normal operation the flywheel 8 charges up sufficiently to rotate shafts 9, 12, for one tap-changing operation after a limit switch for motor 5 is actuated by a member rotating with timing cam 7 to break the motor circuit. Ratchet wheels 14, 15 are arranged for turning in one or the opposite direction through coupling 13, the shaft 12 of a selector switch 17, Figs. 1, 3. Manual operation is provided by a handle (not shown) on the motor shaft 47 which rotates shaft 3 and moves a coupling 2 through a member 50 such that projections 55 on a disc 56 engage a forked plunger 57 and the energy stored in a spring 65 gives a quick action to the tap-changing operation (Fig. 4, not shown).
