Abstract: 1,146,052. Railway vehicle knuckle couplers. SUMITOMO METAL INDUSTRIES Ltd. 24 March, 1966 [7 April, 1965 (2)], No. 13082/66. Heading B7T. The knuckle 2 may be held in its open or ready for coupling position by providing the knuckle with a protrusion 7 adapted to engage in a recess 5 between shoulders 6 in a lower pivot lug or ear 3. At the time of coupling a strong force is required by the mating knuckle to rotate the knuckle 2. In Figs. 9-11 (not shown) the knuckle tail is formed with a rebated surface (11) on which a vertically movable lock member (12) may sit when the knuckle is open. Accidental or vibrational movement of the knuckle to the closed position is prevented by an upwardly inclined cam surface 10 up which the lock must be moved to allow the knuckle to close.

Filed: 1923-05-16
Abstract: 216,327. Coventry Automatic Telephones, Ltd., and Collyer, J. E. May 16, 1923. Electromagnetic relays.-In the magnetic circuit of a relay adapted for use in automatic telephone systems and comprising a core 2, a yoke 4, an adjustable yoke extension 8, and an armature 7, the armature is so suspended from the yoke extension as to provide between n them an air gap of relatively small width but large area, thus forming a joint of low reluctance, and the adjustment of the yoke extension is such as not to effect appreciably the reluctance of the circuit. The armature 7 is pivoted to the extension 8 by a pin 9 of non-magnetic material with the interposition of thin brass washers 10, 11, Figs. 2 and 3, and the extension is bent as shown at 8<a>, Fig. 1, to present a large surface to the armature. The extension 8 is of a cross-sectional area approximately equal to that of the yoke 4 and for adjustment purposes is provided with elongated slots through which pass screws 23, 24 engaging tapped holes in the yoke 4.

Abstract: 839,998. Electrical analogue computing systems. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. June 17, 1958 [April 25, 1957], No. 13229/57. Class 37. In an arrangement comprising a chain of resistances of graded ohmic values shunted by individual switches wherein means are provided for passing through the chain a current quantitatively representative of one quantity, and for selectively opening the switches to insert a resistance quantitatively representative of a second input quantity, the voltage across the chain is measured to obtain the product of the two quantities. The resistors Rb increase in value in accordance with a binary digital notation and the individual switches S1-S16 are respectively ganged to the respective switches S1<SP>1</SP>-S16<SP>1</SP> to remove resistance from Rc identical with that inserted in Rb and thus maintain a constant resistance across the voltage Va and a constant current Ia. The voltage Va which determines the current Ia may be an analogue input or may by, for example, selecting tappings on a potential divider represent a digital input. The product is given by Vab.

[Class 78 (v)] [Also in Group XXI] An oil-well draw-works of the kind in which a drum may be driven through a clutch to haul in rope or braked to retard the paying-out of rope, comprises a rotatable shaft, a hoist drum and a clutch member carried on the shaft and rotatable relatively to one another, friction means between said drum and the clutch member, power driven means connected to the clutch member for rotating it and for driving the drum on engagement of said friction means, and means for locking the clutch member against rotation in at least one direction, engagement of the friction means acting to brake the drum when the clutch member is locked against rotation, such engagement being controlled independently of operation of the power-driven means. The interior of a flange 26 on a winding drum 22 splined to a shaft 20 is adapted to engage frictionally an inflatable tube 40 secured to a flange 38 of a clutch member 36, when the tube is inflated. The clutch member 36 is rotatably mounted on the shaft 20 and may be driven by a sprocket-wheel 34, or may be locked against rotation by sliding a member 60, held against rotation by splines 58 engaging fixed splines 56, to the left in Fig. 1 so that dogs 64 on the member 60 engage dogs 66 on the clutch-member 36: the clutch then operates as a brake. In an alternative construction the member 60 is replaced by a ratchet-and-pawl, so permitting the member 36 to rotate in the driving direction to operate as a clutch but holding it against reverse rotation so that when paying-out it acts as a brake. The pawl is manually releasable. As shown, an auxiliary high-speed drive is provided comprising a member 46 carrying a driving sprocket 48 and adapted to be connected by an inflatable tube 52 to a member 42 splined to the shaft 20, and auxiliary band-brakes 25, 27 may be provided. The drum 22 may be loose on the shaft 20 while the member 36 is splined thereto.
