Patent GB-792540-A (GB)
Abstract: 792,540. Knitting-machines. MONK (SUTTON IN ASHFIELD), Ltd., S. A. Feb. 14, 1956 [Jan. 15, 1955], No. 1297/55. Class 74 (2). A pinion 12 is mounted on the speed-control shaft 10 of an electric motor driving a straightbar machine and is engaged by a quadrant gear 13 which is moved to increase the speed of the machine when the length of the draw is shortened and vice versa. For this purpose a lever 23 is connected to a part of the mechanism 25 which is adjusted when the draw mechanism is simultaneously adjusted to increase or decrease the length of the draw, and such mechanism may be the carrier stop boxes or the adjustable sprocket saddle of a flexible drive. Adjustment of the draw mechanism and of the mechanism 25 therefore operates linkage 15... 19, 21, 22 either to permit a spring 20 to move the quadrant gear 13 to effect an increase in speed, or to move the gear 13 against the action of the spring 20 to effect a decrease in the speed of the machine. A lost-motion connection by pin 15 and slot 16 on rod 17 of the linkage permits the speed of the motor to be decreased, at any time, below that governed by the draw speed, and such decrease may be controlled by fashioning speed control mechanism comprising lever 26, link 27 and arm 28 controlled by cams 30. The motor may also be controlled for speed, stopping and starting by hand control mechanism 33 ... 38 within the speed limited by the draw mechanism.

Abstract: A portable winch having a drum and ratchet wheel 25 mounted upon a frame 10 for rotation about an axis 23, and a hand lever 47, pivoted upon the frame for rotation about the axis 23. A tension-transmitting cable 26 is wound upon the drum, and a releasable stop pawl 35 is pivotally mounted upon the frame and engages the ratchet wheel for permitting unidirectional rotation of the drum. A ratchet dog 53 is pivoted upon the hand lever 47 for movement between an operative position engageable with the ratchet wheel and in inoperative position clearing the ratchet wheel during pivoting of the hand lever about the axis. A coil spring 61 is fixed to the hand lever and extends transversely of the dog projection, the coil spring selectively engaging one side of the dog projection for biasing the ratchet dog into the operative position, and selectively engaging the opposite side of the dog projection for biasing the ratchet dog into the inoperative position. <IMAGE>

Patent GB-2048783-A (GB)
Title: Microballistic printer
IPC: B41J2/22
Filed: 1980-04-23
Abstract: A ballistic impact printer includes a gun 96 for successively propelling balls along predetermined paths to trace a desired character on a medium supported on a platen 20 spaced from the gun. Means are provided for orienting the gun after each ball leaves the muzzle of the gun 59 that the desired pattern is formed. Gas under pressure propels a ball along the bore of the gun, which is slightly larger than the diameter of the ball. This enables the gun to be made out of resilient material, since a gas bearing is formed which prevents a ball from touching the sides of the bore while it is travelling down the bore. The breech of the gun is slightly smaller than the diameter of a ball, so that a ball acts as a seal for a chamber in which gas pressure is being built up. When a ball in the breech is dislodged by a succeeding ball, gas from the chamber performs its propelling action between the time the ball is dislodged from the breech and the succeeding ball is seated in the breech. Balls rebounding from the platen are continuously recycled to a storage bin 170. <IMAGE>

The device is inserted in co-axial bores (15A, 15B) drilled from outside a building through the outer leaf (14) and into the inner leaf (13) of a cavity wall. The nut (8) is tightened to expand the sleeve (4) in the bore in the inner leaf and the nut (12) is tightened to expand the sleeve (10) in the bore in the outer leaf (14). The tightening of nut (8) also expands sleeve (6) to form a water stop. <IMAGE>
Patent GB-2061250-A (GB)
Title: Slurry explosive composition
IPC: C06B31/28
Filed: 1980-10-17
Abstract: An aqueous slurry explosive blasting composition comprises an aqueous suspension of water-soluble crystalline oxidising salt consisting predominantly of ammonium nitrate, which salt has been comminuted in a saturated aqueous solution in the presence of a water-soluble crystal-growth inhibiting surfactant having a hydrophobic portion and a hydrophilic portion in its molecule, in intimate admixture with liquid water-immiscible hydrocarbon fuel sensitiser. The surfactant maintains the oxidiser salt in a finely divided state and ensures that the liquid hydrocarbon remains uniformly distributed throughout the explosive mass as a stable coating of droplets on the salt particles thereby enhancing the explosive sensitivity of the composition. The preferred fuel is diesel oil and many suitable surfactants are given.
Patent GB-2064199-A (GB)
Title: Record Side Identification Apparatus
IPC: G01B7/30
Filed: 1980-11-25
Abstract: The apparatus (164) for a video a disc player comprises a sensing member (250) which is deflected to a first position and a second position in response to insertion of a video disc caddy (12) into the player with a given side thereof respectively facing upward (side 1) and downward. The deflected sensing member is depressed to illuminate the respective one of a pair of record side identification lights on the front instrument panel of the player during further insertion of the caddy into the player. The caddy (12) has a recess (54) in side 2, and the sensing member (250) has two parallel level ramps (280 and 282) each side of a pivot pin (256). If side 2 is upwards both ramps are equally engaged, the sensing member does not pivot, and an abutment member (266) will eventually abut a "side 2" sensing contact. If side 1 is upwards, only one ramp is engaged, because the recess (54) is adjacent the other ramp (282), and the sensing member pivots so that the abutment member will abut a "side 1" contact. <IMAGE>

Patent GB-2069142-A (GB)
Title: Measuring workpiece dimensions
IPC: G05B19/401
Filed: 1981-01-26
Abstract: A numerically controlled machine tool has a tool 12 on a support 13 for machining surface 11A of a workpiece 11, and for sensing the surface for measuring a dimension 43 between it and a datum surface 29. The tool is first moved to a position 44 clear of the surface 11A and an electric circuit 31 between the tool and the workpiece is switched on. The tool is then moved toward the surface 11A by a control system 17 which reads tool position by counter 39. When the tool touches the workpiece the circuit produces a signal 32 to read the content 43A of counter 39 into computer 37. This determines the difference between the actual and demanded dimension of the surface 11A and corrects the tool position accordingly. Alternatively, the signal 32 is produced by a piezo-electric crystal in the tool 12 to sense force when the tool engages the workpiece. Or the tool 12 is allowed to slide on the support, and the extent of the sliding used to measure the difference between actual and demanded dimensions. <IMAGE>

Title: Electrical connector housing
IPC: H01R13/627
Filed: 1981-03-03
Abstract: A housing (12) is provided with a pivotal latching member (21) comprising a pair of parallel arms (22, 22') each having a catch (24, 24') at one end and, at the other end, a finger- engageable release portion (25) extending behind a rear face of the housing. Pivots (23), (23') of the arms snap fit in sockets in the housing and resilient tongues (26), (26') on the housing shell (12) bias the arms (22, 22') to the latching position. Each catch (eg 24', Figure 6) engages with a cooperating latching bar (36') in a second housing (34) compatable with the housing (12) to latch the two housings (12, 34) together. The form of the latching member makes one-hand operation of it possible and hence it is particularly suitable for use in confined spaces. The housing may be used in association with a ballast coil housing for a lighting set (see Figure 7, not shown). <IMAGE>
