Title: Open chamber breech mechanism for firing caseless ammunition
Inventor: DARDICK DAVID
IPC: F41A3/76
Filed: 1968-09-03
Abstract: 1,247,871. Open chamber breech mechanism; caseless cartridges. TRW Inc. 3 Sept., 1968 [1 Sept., 1967], No. 41903/68. Headings F3A and F3C. An open chamber breech mechanism for firing caseless ammunition 12 comprises a carrier member 18 having a firing chamber opening laterally through the surface thereof and being mounted for rotation in a frame member 14 which has an ammunition infeed opening, the carrier member 18 rotating between a cartridge infeed position and a firing position. Obturator means 42 are provided for sealing those interfaces between the members 14, 18 which, in use, are subjected to propellent gas pressure during firing of a round. In the construction shown the obturator means 42 comprise an upper obturator attached to the frame member 14 and sealing around the margins of the firing chamber through sealing means 80, 82 (78, Fig. 2, not shown), the sealing means being urged against the carrier member by the explosion gases. The obturator means 42 further comprise an annular flange 94 on the forward face of the carrier member 18. The firing means 40 is sealed by a flange 102 thereof abutting the rear wall of a chamber 104 containing the firing means. The carrier member 18 is provided with a pair of bearing surfaces 50 which terminate in stop surfaces (52, Fig. 3, not shown) so that the carrier member is mounted for limited oscillation. The rotational axis of the carrier member is eccentric so that the member tends to move away from the upper obturator on movement from the firing position to the infeed position. In a further embodiment (Fig. 4, not shown) the breech mechanism is of the recoilless type. When cylindrical rounds of ammunition are used a pivoted plate is provided in the upper obturator which plate co-operates with the carrier member to form a chamber for the projectile (Figs. 5, 6, not shown). The obturator means may be housed in grooves in the carrier member flexible or pivoted walls separating the means from the pressurized gas so that, in use, the means are compressed in the grooves and thereby urged against the frame member (Figs. 7 to 10, not shown). The ammunition shown in Fig. 1 has an equilateral curvilinear triangular shape in transverse cross-section and the projectile 30 is embedded in the charge 110.

Abstract: An attenuated live measles virus vaccine is prepared by serially culturing a measles virus, that has been adapted to grow in living non-human cells, in a culture medium comprising living non-human animal cells at a temperature below 35 DEG C, but at a temperature higher than that at which propagation of the virus ceases.  The temperature is preferably 28 to 32 DEG C, for part or whole of the cultivation steps.  At least 40 serial passages are required. Avian particularly thick embryo tissue is preferred, but bovine kidney tissue may be used.  The measles virus may be an adapted strain of the Edmonston strain of measles virus e.g. Enders strain.  The strain employed may have been adapted to grow in living non-human cells by serial culture in (a) human e.g. amnion or heart tissue culture and then (b) animal tissue e.g. chick embryo tissue at conventional incubation temperatures e.g. 35 DEG C.  The culture fluid may be Earle's basic salt solution containing 5% calf serum or 10% of horse or lamb serum and 0.5% lactalbumin hydrolipate; or medium 199 with 5 or 10% of horse serum.  The separated virus may be stabilized with lactose glutamate solution and the final vaccine contains a parenterally acceptable diluent or is freeze-dried.

In a brake for a mine winder of the kind which is normally held applied by biasing means, e.g. springs 6, and released by hydraulic fluid supplied by a servo-operated master cylinder 11 having an hydraulic piston 13 of small area operated by a power piston 15 in a pneumatic servo-cylinder 14, the supply of air to the cylinder 14 is controlled by a valve 24 operated manually by a lever 42 through linkage 48, 49, 54, 55, 56, 27 which includes a speed-responsive governor 57, 59, 61, 62, 63 to limit the degree of braking which may be applied as the speed of the winder increases. A weight 53 also acting on the linkage is normally held in a raised position by a solenoid 52, but should a power failure occur the solenoid releases, causing valve 24 to be actuated to release fluid from the cylinder 14 and apply the brake, so far as is permitted by the speed-responsive cam 62. The valve 24 is supplied with compressed air at a pressure of about 70 lbs. per square inch by a line through a check valve 34 and limiting valve 31, the line also including a pressuresensitive switch 32 to switch on a local pump 33 whenever line pressure drops below the desired value. An emergency reservoir 37 can also be connected into the system if a power failure occurs. When brake lining wear occurs this is compensated hydraulically via a valve 21 opened at the end of the return stroke of piston 15 whereupon fluid is supplied via pipe 18 by an accumulator 19 charged with air at 20 lbs. per square inch, set by a limiting valve 41. A water filter 28 and an air lubricator 29 are included in the compressed air system.

Abstract: 933,576. Two-part couplings. CANNON ELECTRIC CO. Dec. 16, 1960 [Aug. 2, 1960,] No. 43334/60. Class 38 (1). In a multi-contact electrical two-part connector 10 comprising plug and socket members 14, 12, respectively, which have tubular metal shells 44, 16, containing insulating bodies 58, 26, carrying pin and socket contacts in bores 36, each contact is provided with an annular groove such as 78, Fig. 2, on its cylindrical body portion for receiving a resilient split metal retaining ring 80 which is compressed by a tapered portion 92 of bore 36 as the contact enters the body until it snaps behind an inclined shoulder 88 of the bore, contact entry being limited by a flange 86 on the contact engaging a shoulder 94 of the bore. Face 84 of the contact is angled such that it tends to cam ring 80 radially outwardly when the contact is pulled, while inclined shoulder 88 of the bore tends to cam the ring radially inwardly. The relative angle between face 84 and shoulder 88 determines the pull needed to remove the contact from the body, face 84 always having an angle of incline to the axis greater than the shoulder 88 (Fig. 5, not shown). The tapered bore and shoulder of the insulation body, which may be of resilient elastomer material, may be provided with a metal sleeve to reinforce the working surfaces (Fig. 6, not shown), or the insulation body may be in two parts, the bores of each part being aligned and of similar shape together to bore 36 (Fig. 7, not shown), an inwardly-directed flange forming an abutment to limit the inward movement of a socket to the contact.

Thus if spring 108 is inserted in the groove with tabs 144 facing the seal 100, then limited rotation of seal 100 will occur in the direction of the arrow of Fig. 7 until the end 146 of a tab 144 engages hole 140 in seal 100, further rotation of the seal and spring being eventually stopped by engagement of end 150 of a tab 148 in hole 136 in groove base 112. The arrangement of tabs 144, 148 ensures this prevention of sealrotation irrespective of the way seal 100 is inserted, i.e. whichever way it faces.
