Abstract: 432,735. Changing signs. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 80, Leyland Road, Lee, both in London. Feb. 17, 1934, No. 5285. [Class 3 (i)] In a sign or indicator comprising a plurality of changeable display elements 1, 2, 3, 4, 5, 6, Fig. 1, the element 2 is capable of more than two changes, while the elements 1, 3, 4, 5, 6 are capable of two changes only. The element 2 may comprise a plurality of slats 12, Fig. 3, mounted on endless chains 10 carried on sprocket-wheels 8, 8<a> driven by an electric motor through chain gearing, or may be an endless band. Between the motor and the gearing is located an electromagnetic clutch of known type having driving and driven members coupled on the energization of an electromagnet and held coupled mechanically on its de-energization until a certain radial position is reached where de-coupling is effected and the driven member held stationary in a place which ensures the correct registering of a slat 12 at its window. The sign is double-sided, one motor driving the duplicate mechanisms. Over the window of the element 2 a pivoted counterweighted shield 21 is arranged to conceal the element during its change, and to fall down to reveal the element when stationary. The two shields on opposite sides are coupled together to move in different senses, and are actuated by a solenoid-operated pitman having an adjustable stroke, and completing after retraction of the shields a circuit whereby the auxiliary elements 1, 3, 4, 5, 6 are turned to show an indication. The elements 1, 3, 4, 5, 6 comprise triangular spring-biassed prisms 38, 39, Fig. 4, mounted on shafts 36, 37, those on opposite sides of the sign being coupled together and actuated by a solenoid 44 similar to that operating the element 2. Each prism shows either a blank face or a face bearing a legend &c., and shutters similar to the shield 21 may be provided. The electrical control is on a central board, closing of a selected switch effecting movement of the element 2 to the required display. Specification 427,413, [Group XXIV], is referred to.

Abstract: 922,106. Serial binary adders. HAZELTINE CORPORATION. Feb. 13, 1961 [Feb. 24, 1960], No. 5331/61. Class 106 (1). A serial binary adder receiving at A and B binary numbers (least significant digits first) comprises " and " and " or " circuits 17, 16 the outputs (negative voltage signals) of which are connected to a gate circuit 20 and a bistable carry circuit 18, the latter also receiving clock pulses from source 15; it switches to " carry " on receipt of an output from 17 and to " no carry " on receipt of a clock pulse unaccompanied by a signal from 17 or 16. The output of 18 is presented as a third input to circuit 20, and acts on a circuit 19 to produce instantaneously at its output a positive voltage when 18 is switched from " carry " to " no carry, " a negative voltage when 18 is switched from " no carry" to "carry," and zero output when 18 remains unchanged; this output forms the fourth input to 20. " Carry output of 18 is a negative voltage, and " no carry " is zero. Circuit 20 effectively determines the " average " potential of its inputs, and provides a 1 or 0 output at 21 according as it is above or below a certain negative voltage. Fig. 3 (not shown), illustrates transistor gates and flip-flops built up into an adder circuit of the Fig. 1 type, and Fig. 4 (not shown) illustrates a modification using two bi-stable circuits in place of unit 19.

Abstract: 379,317. Television. WALTON, G. W., 2, Dean Street, Soho, London. Feb. 20, 1931, No. 5426. [Class 40 (iii).] According to one aspect of the invention, an image of the object to be transmitted is traversed over a scanning aperture, the light forming the image being continuously changed in colour. According to another aspect of the invention, applicable to cinematography as well as television, a uni-dimensional image is formed as in Specification 328,286, [Class 40 (iii), Telegraphs, Electric], the light forming the image being continuously changed in colour. In one arrangement, a coloured object 1, Fig. 1, is associated with optical apparatus 2 .. 7 forming a uni-dimensional image on a film 20. A rotating disc 22 is placed in the system, whose colour transmission varies circumferentiallv continuously as in Fig. 3 ; or a disc having distinct sectors of different colours as in Fig. 4 may be used so that the colour of the record on the film changes continuously. In reproducing, the film 20, Fig. 2, passes before a narrow slit, and light from a suitable source passes through the film to an optical system similar to that of Fig. 1 and containing a similar colour disc 22 rotating so that the image 1 is reconstituted in colour. The film 20 may also carry a record of the speed of the motor driving the disc 22 which controls the speed of the disc at the reproducer. The disc 22 may also have filters such as a photographic deposit to compensate for the actinic values of the various colours. In a modinoatiion, an object 1, Fig. 5, forms a uni-dimensional image 9 which is reflected by an oscillating mirror 24 (or a mirror drum) into a plane 25 containing a stationary filter 26 whose colour transmission varies across it. The image 9 is traversed over the filter 26 to form a record on a film. In reproducing, the film is passed across the filter 26 and the mirror 24 oscillated, the optical system building-up the normal image at 1. In a further modification, the uni-dimensional image is formed at 9, Fig. 6, and light passes through a prism 27 to a slit 28. The prism is oscillated, say at 10 per second, and the light at 28 varies in colour. Specification 369,644 is also referred to.

Title: Spring balancer
IPC: B25H1/00
Filed: 1940-03-29
Abstract: 535,884. Balancing. CHICAGO PNEUMATIC TOOL CO. March 29, 1940, No. 5700. Convention date, June 27, 1939. [Class 78 (ii)] [Also in Group XXXII] A balancing device for suspending a tool &c. comprises one or more readily detachable helical springs 19 and means for enhancing the safety of the device in use. The spring 19 is contained in a casing 14 attachable by a cover 16 and nuts and bolts 15 to the balancer frame 1, the outer end of the spring being fixed to the face 2 of the frame 1 and the inner end to a sleeve 22 slidable without relative rotary movement on the main shaft 3. The casing 14, or a liner 17 thereto, has a plurality of internal projections 18 which keep the spring 19 from filling the casing when loosened, so facilitating insertion and removal and lessening friction. The suspension cable 13 winds on and off a fusee drum 11 mounted rotatably on the shaft 3, but fixedly adjustable thereon by a worm 23 carried by the drum and gearing with a wheel 24 fixed on the shaft 3. This permits the initial tension of the spring to be altered to suit the load. A gravity retracted latch 25 is provided to hold the drum 11 in position either by hand or automatically when the spring breaks and also to limit the rotary travel of the drum. The drum is furnished with a plurality of internal projections 31 between any two of which the head 30 of the latch 25 can rise and so bring up the drum to a stop after a part turn. Rubber inserts 32 on each side of the latch cushion the blow, and a retaining plate 33 for the inserts assists also in guiding the latch. The manual operation of the latch is effected by a plate 24 the lower end of which surrounds a pin 37 extending from the latch. Lost motion between the latch and the plate 34 allows the latter to be slid by a finger-piece 35 to raise the latch, and to remain stationary, helped by a detent 38, when the latch rises from other causes. Raising of the latch when the spring breaks is effected by contact of the outer band of the spring with the pin 37. The latch is lifted at end positions of the drum rotation by a Geneva stop mechanism, the pin 43 of which is carried by the drum 11 and the slotted side 40 of which is journalled on the frame face 2 and has a stud 41 which bears on the bottom of the latch 25 at the end of each oscillation of the disc. Specification 263,185, [Class 78 (ii)], is referred to.
