Title: Sabot projectile
IPC: F42B14/06
Filed: 1970-07-06
Abstract: 1321264 Sabot projectiles PACIFIC TECHNICA CORP 6 July 1970 [29 Aug 1969] 32643/70 Heading F3A A sabot projectile comprises a sub-calibre core 16, Fig. 2, and a discardable sabot comprising a base portion 38, a cylindrical portion divided into segments 22 by slits which extend longitudinally over part of the length of the cylindrical portion, and a tapered nose portion 24. Weakening grooves 46 are provided in the nose portion. A band 44 holds the segments 22 together. Upon firing the projectile through a rifled barrel, a plastics or soft metal driving band 12 causes the projectile to rotate. When the projectile emerges from the barrel, the band 44 is broken as the segments 22 being to separate under the action of centrifugal force. The separation of the segments is initiated at the aft end of the segments and progresses forwardly. The nose portion 24 also disintegrates into segments defined by the weakening grooves 46. The separation of the cylindrical and nose portion segments is assisted by the muzzle gasas from the firing weapon. The sub-calibre core 16 and the sabot base portion 38 are separated through the greater air resistance of the base portion. In a modification (Fig. 6, not shcwn) the longitudinal grooves dividing the cylindrical portion into segments have a sawtooth configuration. In another embodiment, Fig. 8, the cylindrical and nose portions of the sabot are integral and the grooves 64 which divide the cylindrical portion into segments increase in depth rearwardly but do not extend to the surface of the sub-calibre core. A bore 70 enables a tracer, carried by the sub-calibre core, to be ignited by hot propellant gases. The subcalibre core may comprise a mass of dense material or one or more flechettes, or may be explosive.

Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q3/42
Filed: 1928-11-08
Abstract: 324,985. Standard Telephones & Cables, Ltd., Lowry, L. P., and Hardwick, J. R. Nov. 8, 1928. Automatic exchange systems; metering.- Booster battery metering is employed in registercontroller systems, the metering being effected by two relays in the first code switch. When the switch is ta.ken into use L, B, A and EA operate and DM steps in search of a free A-digit switch, when K operates in series with DM extending the loop and the circuit of relay A to the registercontroller. The impulses are dialled into the controller and A responds to the translated digits pulsed out, relaying them first to the vertical magnet V of the switch shown and afterwards to subsequent switches in the train. When the called subscriber replies, D operates over the reversed battery condition in the called loop releasing A and MD (which operated when relay H of the switch shown switched through). Relay E operates disconnecting the guarding earth and connecting the booster battery to the release trunk RT to meter the call. The circuit of EA is broken and this relay releases slowly removing booster battery and reconnecting a guarding earth. When the calling party releases, relay L falls back releasing the switch and homing the A-digit switch finder. Permanent loop, or partial dialling. After a predetermined time, if no digits or an incomplete sequence have been pulsed into the register-controller, the register-controller releases and returns earth over wire PU releasing relay L. Relay B releases and M operates re-operating Land B and lighting the lamp SL. If the subscriber now dials the switch steps to the first level when N changes over and H operates completing a circuit for MD. Number unobtainable tone is returned to the subscriber from NU wire over QA. Eleventh step busy condition; statistical metering. When the switch moves to the eleventh step, springs S change over returning busy tone from BY and connecting earth to FP to register a call on the overflow meter.

Title: Control of tension in a textile strand
Inventor: STANLEY ROBERT KENNETH
IPC: D02J1/22
Filed: 1964-08-17
Abstract: Tension in a textile strand, which, as it is being unwound from a package, is moved laterally to and fro, is equalised by passing the strand around a plurality of rotating rollers arranged so that the strand path is a succession of alternately straight and curved increments of path, and then to a laterally fixed guide. The rollers may be driven and the guide is preferably a flanged roller guide. The strand may then be drawn and/or stuffer-crimped, or separated into component filaments for winding or twisting.  The strand tension may be further controlled by providing the package support with a fluid actuated brake cylinder, and by passing the strand after the roller guide around two rolls (Fig. 5, not shown) one of which is movable by the strand when the tension varies and is connected to a ball valve to vary the bleed rate of the fluid in the supply conduit to the cylinder.
