Title: Fragmentaion missile
Inventor: JR GUY CHARLES THRONER
IPC: F42B12/32
Filed: 1960-04-11
Abstract: 935,707. Fragmentation type missiles. AEROJET-GENERAL CORPORATION. Nov. 11, 1960, No. 38904/60. Class 9 (1). A fragmentation type missile, e.g. a missile warhead, bomb or grenade, includes a plurality of slugs coated with a material exhibiting pyrogenic properties upon frictional impact with a target. The missile shell 1 has an outer casing 2 and an inner casing 4 between which is a sheath of presized steel slugs 3. Both casings are preferably composed of a fibre glass reinforced plastic resin, such as an epoxy resin, and the steel slugs 3 are preferably cemented to each other and to the casings by means of a plastic resin 6, such as an epoxy resin. Each slug 3 is provided with a coating 5 of a pyrogenic material which is ignited by the friction developed between the slug and the target. Metals or alloys which can be tightly bonded to the slugs are preferred, examples being Al, Mg, Zr, Ti metals and Mg-Ti, Al-Ti, Al-Mg, Al-Zr, Al-Zr-Mg alloys. The interior of the casing 4 is filled with a suitable high explosive in the usual manner.

Title: A Guided Missile having a Control System for Controlling Transverse Acceleration and Roll Damping
IPC: G01C21/16
Filed: 1967-08-24
Abstract: 1,194,566. Automatic control of missiles. BÍLKOW G.m.b.H. Aug.24, 1967 [Aug. 24, 1966], No. 38985/67. Heading G3R. A rocket-propelled guided missile which is gyro-stabilized about its roll axis is stabilized about its pitch and/or yaw axes by electrical control systems responsive to signals from accelerometers only. In Fig. 1 a rocket-propelled missile has a roll attitude gyro KM 3  and five linear accelerometers KMi - KM 7  located as shown relative to roll, pitch and yaw axes X, A 1 , A 2  of the missile. Electrical signals from the five accelerometers are applied to a computer (not shown) which takes into consideration the location of each accelerometer and derives signals corresponding to the accelerations of the missile along and about its axes. Different combinations of these signals are compared with signals representing desired accelerations so that any differences are effective to maintain desired accelerations by controlling electro-hydraulic actuators associated with pairs of control surfaces 13, 13a, 14, 14a. The signal from the roll attitude gyro in combination with the signal representing roll acceleration serves to maintain a desired roll attitude. Networks having suitable time-constants are included to improve stability. A modification, in which the computer derives acceleration signals in combination instead of separately from three accelerometers only, is described.

Abstract: 1,091,913. Compacting powders. MARTIN BROS. (TOOLMAKERS) Ltd. Sept. 1, 1965 [Sept. 30, 1964], No. 39723/64. Heading B5A. In a press for compacting metal, ceramic or plastics powders into coherent bodies suitable for subsequent processing, e.g. sintering, objects of irregular thickness are produced with even compaction within a die 2 by transferring a portion of the die charge, without change of volume, between punches 8 and 4 moving downwardly in unison prior to compaction within the die 2 between upper punches 7, 8 and lower punches 4, 5, 3. Bottom punch 5 is fixedly supported on fixed press-plate 10 with rigidly interconnected plates 1 and 11, movable with respect thereto, fixedly supporting die 2 and core pin 6. Bottom punches 3 and 4 are carried on rods 12, 13 and are urged upwardly by light springs 56, 60; top punches 7, 8 are carried by a plate 15 which is swung into position, after die 2 has been filled from a sliding hopper, and then lowered so that punch 8, which is loaded by air pressure within punch 7, contacts the top of the material M in the filled die 2 simultaneously with the engagement of rods 29, fixed to rods 12, by push-rods 33 connected by strong springs 51 to the plate 15 whereby the punches 8 and 4 move in unison as plate 15 continues to descend until punch 4 is halted by abutment with plate 10 at the same time as punch 7 contacts the top of the material M in the die 2. Continued downward movement of plate 15 compresses springs 51 and compacts material M by punches 7, 8, the punches 4, 5 remaining stationary and the punch 8 being engageable by a top wall (9) within punch 7 (Fig. 3, not shown); the interconnected plates 1 and 11 also move downwards carrying die 2, punch 3 and core 6 relative to punches 4, 5 with the downward movement of punch 3 limited by abutment with members (19) (Fig. 5, not shown) on plate 10. After completion of the compaction, the plate 15 is raised and the descent of plates 1 and 11 is continued whereby members (19) are laterally displaced by the engagement of angle members (20) with rollers (24) thereon (Fig. 4, not shown) to permit continued displacement of punch 3 into contact with plate 10 and the descent of plates 1 and 10 is halted with the top of die 2, core 6 and punches 3, 4, 5 level so that the compacted article is displaced by the returning hopper. The core 6 may alternatively be omitted with solid punches 4 and 8.

A reciprocatory or rotary member 2, such as the plunger of a gas compressor, is sealed by means of a stationary sleeve 7 on which are mounted a number of contiguous collars 8, 9 contained in a cylindrical chamber 5 in a body 1 and each having at one end an annular recess 8a which is formed around the inner periphery of the collar and which contains a sealing ring 14 of rubber or rubber-like material, the sleeve being provided with ports 17 whereby leakage fluid can pass from the clearance between the sleeve and the member 2 to one side of each of the rings 14. The plunger 2 reciprocates in a cylinder 1a in the body 1 provided with gas inlet and outlet 3, 4. A further sealing ring 14 is contained in a recess at the end of the chamber 5 adjacent the cylinder 1a. Each ring 14 is flanked on one side by a metal ring 15 which has equi-spaced pegs 16 extending through holes in the ring and in the next collar. A collar 10 adjacent the collar 9 is formed with an annular recess 12 in which a flange 13 on the sleeve 7 is locked by a cover 6 and with an annular recess 18 in communication with the clearance space between the sleeve and the plunger by means of radial ports 19 and, through passages 20, 21, with a source of low pressure. Lubricant is fed between the sleeve and the plunger through a passage 23, recess 12 and ports 24. Gas leaking past the sealing ring 14 is drained at 22 and returned to the inlet 3. In operation, the rings 14 are compressed into contact with the sleeve 7 by progressively diminishing gas pressure so that the pressures acting on the inner and outer surfaces of the sleeve are practically balanced.

Abstract: 1,271,415. Hydrostatic transmission. ROBERT BOSCH G.m.b.H. 12 Aug., 1969 [13 Aug., 1968], No. 40256/69. Heading F2D. An hydrostatic transmission for a fork-lift truck comprises an adjustable pump 2 connected to a motor 3 driving a wheel 4, the pump being adjusted by a servomotor 6 to which control fluid is delivered by an engine-driven auxiliary pump 15 through a line 14 and a reversing valve 33, the line 14 being also connected by lines 16 and 24 to multiposition throttle valves 18, 26 positioned by a brake pedal 19 and a throttle pedal 27 respectively, to control the servo 6 and hence pump 2. As shown, with the brake and throttle pedals released, valve 18 is closed and valve 26 is fully open to relieve line 14 and allow springs 9 and 10 in servo 6 to hold the pump in neutral. On depressing the throttle pedal 27, valve 26 begins to close to allow line pressure 14 to rise and the pump displacement to be increased. On depressing brake pedal 19 to brake the truck through linkage 21, line 14 is relieved and the truck stops. The throttle pedal is still depressed to allow full engine-power to be used to raise the forks, partial brake release allowing inching drive of the truck. Again, Fig. 2, (not shown), the brake valve 18 is replaced by a spool valve acted on at one end by pressure in the main pump/motor line, and at the other end by the brake pedal 19 which is also acted on by opposing springs.
