IPC: H04N3/08
Filed: 1931-05-20
Abstract: 366,392. Electric signalling systems. VOROBIEFF, A., 79, Boulevard Haussmann, Paris. May 20, 1931, No. 14906. Convention date, May 24, 1930. [Class 40 (i).] An object or image is explored by two optical systems 1, 2, one of which projects the rays with a continuous movement in two dimensions to the other which cancels the movement in one dimension so that the projected image sweeps over a fixed light-sensitive device 4 alternately in opposite directions. As shown, the optical systems comprise mirrors rotating in opposite directions about an axis inclined relatively to the plane of the mirror, but rotating prisms may be used, Figs. 2 and 3 (not shown). The light-sensitive device is at an aperture in a screen 3 on which the rays are projected. The movement of the object in a direction parallel to the exploration may be indicated by a series of neon lamps connected by independent line wires to a commutator at the transmitter. The luminous signal may be supplemented or substituted by audible signal.

Title: Improvements in universal joints for transmission shafts
IPC: F16D3/62
Filed: 1924-06-21
Abstract: 235,396. Linley, C. M. June 21, 1924. Universal joints of the kind comprising flexiblyconnected spider arms. The flexible material is in the form of a polygonal band supported, as by radial spreaders, so as to cross the arms substantially at right-angles. The band may be of leather, vulcanized or otherwise treated fabric, or other material. As shown, the spider arms 3, Fig. 1, are connected by two-ply bands 4 of webbing held in square form by floating spreaders 10, 11, whereby the original angular interval between the arms 3 is maintained when the shafts are inclined. The spreader 10 is adjustable in length to take up stretch and traverses a clearance hole in the spreader 11, which may also be adjustable. These spreaders have flanged ends 12 to engage the band sections, the looped ends of which are expanded by pins 7 to jam them between studs 6, displacement of the bands being prevented by plates 8, which are secured by split pins 9 on the ends of the studs 6. The coupling offers substantially no resistance to limited lateral displacement of the shafts. In a modification Fig. 4, the arms 3 terminate in flat surfaces 16, to which an endless band or a band 4 in one or two lengths is secured by clamping-plates 17 and screws 18, the ends being overlapped or, as shown in Fig. 5, folded over plates 23. 24 and held against a flat surface 21 on the arm 3 by a bolt 25 and washer 27; an abutment 22 takes the pull of the band in one direction of drive. One of the spreaders may be formed with convex bearing-surfaces co-operating with surfaces on the shaft ends or on the arms to transmit end thrust.

Title: Electric fuse elements and fuses
IPC: H01H85/10
Filed: 1923-11-30
Abstract: 228,949. Ross, F. A. Nov. 30, 1923. Fusible cut-outs.-A fusible element having one or more sections of reduced current carrying capacity is made with a strip of gauze or perforated metal as a basis. The gauze may be composed of wires having different melting points. The sections of reduced capacity are produced by local removal of one or more strands of wire or portions of the perforated plate or by lapping over the end portions of the element or depositing additional metal thereon. The mesh or holes may be filled in or bridged at any part or parts of the element with a metal which melts at a different, usually lower, temperature from the melting point of the gauze or strip. Bridging members may take the form of wires, strips or tubes. To throttle any arc upon fusing, the element may be wholly or in part enclosed with a refractory cement, and thus may form part of the end closure of the cartridges preferably dustfilled in which the .element is housed. The low temperature fusing metal may be received within contact-making tails providing cavities for this metal so that the whole of the load may be thrown upon the high temperature fusing metal when the former metal melts. Cavities around the fuse element within the ends of the container or fuse-enclosing tube may be used for the same purpose. To further ensure that the metal of the members shall not remain in a molten state in contact with the reduced section of the fuse they may be enclosed or carried with a non- inflammable non-conductor which may char under heat but will separate the low and high temperature fusing metals. Figs. 4 and 4<a> show a fuse composed of perforated aluminium or copper b having a reduced central portion bridged with parallel tin wires c which traverse the element and are held by lapping side extensions d of the perforated metal over their ends f. As shown in Fig. 5 a low fusing point bridging strip may be riveted or otherwise attached over the reduced section a. Such fuses mav be enclosed in an asbestos container filled with silica dust and sealed with cement at its ends, through which the ends of the fuse project. The fuse may pass out through asbestos tubes of small diameter set in the cement which throttle back any arc. Fig. 9 shows a fuse formed by two strips of copper gauze e, each with a reduced portion, and parallel wires c of which may be. separated from the gauze by a refractory cement such as a paste of ground silica and silicate of soda or a wrapping m of asbestos paper or a paper or fabric rendered non- inflammable and charring under heat or partly by each means. The cavity formed in this way allows the molten metal to drop into cavitied end contact tails n, which may be flexible, bolted to the ends of the fuse. Arc throttling tubes around the fuse may be constituted by extensions of the cement end seals j. Where a fuse cartridge is enclosed in a carrier or handle subsidence cavities p may be formed in the end contact of the carrier as shown in Fig. 10<b>. In another form, Fig. 11, the cavities are formed in the ends of the container.

Title: Improvements in and relating to induction voltage regulators
IPC: H01F29/12
Filed: 1928-05-24
Abstract: 291,058. British Thomson-Houston Co., Ltd., (Assignees of West, H. R.). May 25, 1927, [Convention date]. Transformers.-The rotor of an induction regulator is adjusted through a worm-wheel 16 and 17 from a shaft 18 carried in bearings 23. The vibration due to t'he alternating torque on the rotor is absorbed by springs 24, 25 located between the worm 17 and end thrust ball bearings 22. The springs 24 are heavy and stiff enough to provide a resilient cushion even under maximum load conditions, but are under little or no compression when there is no torque on the rotor, thus facilitating assembly. The springs 25 are light and weak and are always under compression so as to prevent chattering when the bearings are not subjected to the pressure of the springs 24.

The output of a feed-water pump for a boiler is regulated by means including a chamber 13 in communication with the boiler steam outlet pipe 1, a valve device 2 which controls the quantity of steam flowing to chamber 13 in accordance with the steam flow through pipe 1, a controlled exhaust outlet 17 from the chamber, and means to vary the feed-water pump output in accordance with pressure variations in the chamber. A hinged vane 9, urged to the vertical position by its own weight, takes up a position according to the steam flow through pipe 1 and so varies the degree of opening of a pair of rotary cylindrical valves 2 carried one at each end of the hinge pin of the vane. The outlet 17 is controlled by a plug valve which is set by hand to vary the area of the vent provided. The pressure in chamber 13 is applied to the underside of a piston 24 where it acts in opposition to a spring 31 which loads towards the open position the valve 26 carried by the piston. Valve 26 controls the steam supply to a turbine driving the feed-water pump.

Abstract: 1307906 Feeding and delivering sheets EASTMAN KODAK CO 2 April 1970 [2 April 1969] 15637/70 Heading B8R Sheets are separated from the top or bottom of a pile 4, Fig. 1, in a removable magazine 1, by rollers 2 or 3, Figs. 1, 2 and 3, and passed through channels 5 or 13 to a roller 10 which forwards them to a working station in a channel 16, the rollers 10 and 2 or 3 returning each sheet to the opposite side of the stack. The rollers 2, 3 are spring-urged towards each other so as to engage a pile of any height. The rollers 2, 3 are mounted on an arm 26 movable to the full or chain line position, Fig. 3, according as a sheet is to be separated from the top or bottom of the pile, and the direction of rotation of the rollers 2, 3, 10 being reversed accordingly. The channels 5, 13 are separated by a two-part comb member 7, the lower part of which, together with the channel wall 8, can be pivoted about hinges 7a, 8a so as to vary the distance between the channels according to the height of the pile, the wall 8 being connected to an arm 28 carrying a bracket 29 coupled to the lever 26 by a pin-and-slot connection. In operation, when a sheet is taken from the top and returned to the bottom of the pile, the leading edge actuates a switch 23 to de-energize the roller 2 and then abuts a stop 11 which moves to actuate a switch 24 and de-energize the roller 10. When the processing of the sheet (e.g. viewing or projecting a microfilm) is completed, a manually operable switch re-energizes the rollers 2, 10 to separate the next sheet, while the roller 10 delivers the processed sheet to the roller 3, which is energized when the trailing edge passes a switch 22 and de-energized after a time delay when the trailing edge passes a switch 21. For feeding from the bottom, the switches 23, 22 control the rollers 3, 2 respectively, and the roller 2 is finally de-energized by a switch 20.
