Title: Improvements in or relating to the mounting upon any type of vehicle means for dispensing and locking a safety strap
Inventor: PETTY JOHN WILLIAM LEDWARD
IPC: B60R22/405
Filed: 1962-10-15
Abstract: 1,068,344. Safety harness. NORRIS BROS. Ltd. Oct. 14, 1963 [Oct. 15, 1962], No. 38999/62. Heading A3V [Also in Divisions B8 and F2] An apparatus for dispensing and locking a safety belt comprises rotatable means upon which the belt is wound, pivoting detent means operable to engage ratchet teeth, and actuating means for the detent means adjustable to any one of a number of positions. The casing 41 houses a drum 40 on which the safety belt is wound. The drum has a disc 43 which supports three pivoting pawls 44 with followers 45 engaging slots in the drum. The casing has an annulus of ratchet teeth 47 with which the pawls co-operate to arrest the drum when the cammed head 48 on a stem 49 supported within the drum is moved by displacement of a bobweight 56, part of which is in contact with a pivoted lever 52 which contacts the end of the stem 49. The bobweight is supported by a plate 57 adjustable on a spindle 53 which extends into the sides of a cap 58 and which pivotally supports the lever 52. The cap is rotatable on the casing to adjust the position of the bobweight. If the casing is used in the vertical position the bobweight directly abuts the end of the stem 49. In an alternative form the bobweight 93 and pawl 96 are mounted on one shaft 86 spaced from another shaft 80 on which the belt is wound and which supports a ratchet wheel 77 with which the pawl co-operates. A belt retracting coiled spring is secured at one end on the shaft 80 and at the other end to the shaft 86. A bolted sleeve surrounding a bush secured to the pawl can be adjusted to vary the position of the pawl. The sleeve is integral with a tappet 98 which counterbalances the pawl. The bobweight is supported by an arm on a support adjustably positioned on splines on the shaft 86. The head of the bobweight abuts the tappet 98. The bobweight is displaced by acceleration, deceleration and change of altitude or direction of the apparatus.

Title: Apparatus for condensing vapor on ice
IPC: B01D3/06
Filed: 1962-01-01
Abstract: Vapour is condensed by conducting it into the top of a chamber in which are supported, one above the other, a plurality of trays each of which is supplied with a slurry of ice in water.  The ice melts as it brings about the condensation of the vapour, and the mixture of condensate and water flows through holes in the trays and is withdrawn from the bottom of the chamber.  The trays may be annular troughs each containing two, semi-circular, perforated, plastic pipes.  The slurry of ice in water is distributed around each tray by pumping the slurry through the perforated plastic pipes. Conventional cooling coils may be disposed below the bottom tray. The condenser chamber is described in conjunction with a system of separating potable water from sea water by vacuum evaporation of water from the sea water, and condensation of the vapour.

Title: Digital multiplier
IPC: G06F7/60
Filed: 1957-12-19
Abstract: 848,646. Digital electric calculating-apparatus. BENDIX AVIATION CORPORATION. Dec. 19, 1957 [Jan. 11, 1957], No. 39545/57. Class 106 (1). A device for producing a train of electrical pulses corresponding to the product of two numeric factors and spread out approximately evenly in time, comprises means for serially recirculating for a number of times equal to the multiplier a number equal to or derived from the multiplicand expressed as a binary fraction, and means for generating pulse trains of frequencies proportional to successively descending powers of two, related respectively to the digits of the multiplicand, the arrangement being such that the pulse trains are passed to an output only when they are related to a signicant multiplicand digit. In the multiplying device shown in Fig. 1 the multiplicand is entered in a shift register 14 and the multiplier is represented by an equivalent number of pulses applied on a line 35 to a binary counting circuit comprising an adder 34 and shift register 12 which initially contains zero. A multiplier pulse is entered at the beginning of each shift cycle, and every first " 1 " " non-carry " pulse passed from the adder 34 to the input of the register 12 is detected by a circuit 36 and gives rise to pulses indicated in Fig. 4 in rows T 1 . . . T 5 . The binary representation of the multiplicand in shift register 14 which is circulated in synchronism with the shift register 12, controls the passage of these pulses via a gate 38 to a counter 40 which registers the product. Only when a " 1 " multiplicand digit appears at the gate 38 will the simultaneous " non-carry " pulse be passed to the product counter. An exact result would not be obtained in all cases but accuracy could be improved by increasing the number of stages in the shift registers. Detailed circuitry is described in which the shift registers comprise magnetic cores coupled by diode-capacitor transfer circuits, and circuits 34, 36 comprise a network of gates and bistable multivibrators (Fig. 3, not shown). Reference is made to automatic pulse control of machine tools, where the approximately uniform distribution of the output pulses is particularly advantageous. Specification 829,824 is referred to.
