Abstract: 1,236,927. Compressible mould walls. NATIONAL RESEARCH DEVELOPMENT CORP. 30 Sept., 1968 [6, Oct., 1967; 30 May, 1968; 16 July, 1968], Nos. 45926/67, 25989/68 and 33921/68. Heading B5A. A wall member for use in defining mould cavities between the platens of a press, has one or more wall surfaces and is non-resilient and reducible in dimension in the direction of pressing. The wall members are intended to divide the large area between the platens into two or more smaller areas and are intended for use in moulding concrete slabs where water in the concrete is removed under pressure. Various embodiments are described. In the embodiment of Fig. 1, the wall surface 16 is defined by a lower member 12, a sliding element 10 and a clamping member 14. The clamping member 14 is pivoted at 20 and biased against the sliding member 10 by screw 28, locknut 30 and spring washer 34. Under pressure the sliding element 10 is forced into the cavity between members 12 and 14 reducing the height of the wall. In the embodiment of Fig. 3, the wall surfaces are defined by elements 100, 106 and 102 and elements 100, 104 and 102. Pressure on members 100 and 102 forces these members together and members 104 and 106 apart against the force of spring 122. In the embodiment of Fig. 5, the upper and lower members 200, 202 are separated by a polystyrene strip 204 and an expanded metal mesh 207, 207<SP>1</SP>; the polystyrene compressing non-reversibly when the platens are closed, so that this strip must be replaced before reuse. The upper member 200 carries a bolt 208 and flange 222 and a conical member 224 with a flange is attached to the lower end of the belt. a frusto-conical member 214 engages the outside of the cone 224 and is held in place by a tension band 216 in groove 218 and a compression spring acting against flange 222. When the members 200 and 202 are forced together by the press platens, the frustoconical member 214 is forced downwards with the wedge and prevents expansion of the element when pressure is removed. In the embodiment of Fig. 8, the upper and lower members 510 and 512 are held apart by spring 532 before compression and are held in the compressed position by a ratchet comprising members 536 and 537. The mould wall is defined by parts 550 and 552 of upper and lower members 510 and 512 and by plate 542 which is biased into engagement with upper and lower members by a spring 548. In other embodiments the upper and lower members are in the form of beams of regular cross-section spaced by a material which compresses irreversibly. A mould wall construction for use when the concrete contains reinforcing wires is also shown. Preferably the mould walls are mounted on a frame structure which allows them to move longitudinally along the edge of the moulding in the first stage of removal therefrom.

Abstract: 1,030,867. Selective printing. W. & T, AVERY Ltd. Sept. 13, 1962 [Sept. 23, 1961], No. 34132/61. Addition to 980,077. Heading B6F. [Also in Divisions G4 and G5] Apparatus for indicating or printing information transmitted by electric signals comprises an oscillating shaft 3 carrying a number of wheels 4 with type faces 6 on their peripheries or driving wheels with type on their peripheries, the wheels being connected to the shaft so that they rotate therewith until arrested with selected type faces positioned at a printing or viewing point, the arresting means being controlled by the electric signals in conjunction with the scanning of a code pattern 21 on a member 20 common to all the type wheels. Each wheel 4 is recessed to accommodate a hub 10 fixed to the shaft 3, and is connected to its hub by a spring 8 tending to rotate it relatively to the hub; such rotation being limited by a pin-and-slot 9, 11. During an oscillation of the shaft 3, each wheel moves with the shaft until it is individually arrested by a pawl 17 engaging one of a series of teeth 5 arranged on the part of its periphery not occupied by type faces. Each pawl 17 is operated by its electromagnet 18 against the action of a spring 19 and after operation is held in engagement with the teeth by the pull of the spring 8 on the wheel. As shown, the member 20, which carries a 4-bit binary coded pattern 21 of conducting and non-conducting areas, rotates with the shaft 3 and is scanned by four fixed brushes 22, but the member 20 may be fixed and the brushes 22 moved. The signals picked up by the brushes are fed at B, Fig. 2 (not shown), to circuits 23 of which there are four corresponding to each electromagnet 18 and to which four-part binary signals are fed at A. If the signals at the points A and B of each of the four circuits 23 associated with a particular electromagnet 18 all agree a zero voltage will be applied to an associated amplifier 25 causing the electromagnet 18 to be operated.

Filed: 1938-11-24
Abstract: 529,232. Calcining lime slurry. AHLMANN, N. Nov. 24, 1938, No. 34227 [Class 51 (ii)] In a process for calcining the lime slurry called mesa hot gases are passed through a porous layer of the slurry of such thickness that part only of the layer is calcined and the remainder only dried or partly calcined, and the latter is then mixed with raw slurry to form further porous material to be calcined. As shown the hot gases are drawn by a fan through an inlet pipe 17 and rotary drum grate 1 into which the slurry is fed by a worm 12 and against which the slurry is held by the internal gaseous pressure. An externally adjustable scraper 22 divides the calcined layer from the drum adjacent the dried or partly calcined layer, which latter falls by gravity into a worm conveyer 21 having been further dried by the induction of cooling air through the segment of the material opposite the part of the hood 18 above the air sealing wall 14 within the drum. The dried or partly calcined material is led by the worm 21 and a conveyer to a drum mixing it with fresh raw slurry, the porous mixture being then fed into and evenly over the drum grate 1 by a worm 12 located in a trough of outwardly decreasing depth. A worm 20 leads off the calcined material. Specifications 404,018, 407,077, [Group V], 470,013 and 524,232, [Group V], are referred to.

Title: Coiling of metal tubing
IPC: B21D11/06
Filed: 1970-07-17
Abstract: 1308504 Curving; coiling; rolling tubes DEMAG AG 17 July 1970 [18 July 1969] 34737/70 Headings B3E and B3M A process for the coiling of hot metal tubing is characterized in that the tubing is fed through a bending device 7 and is then laid down in a series of turns, the bending device imparting to each portion of the tubing a curvature corresponding in radius to the turn in which said portion is to lie, and the speed of the tubing as it passes through the bending device and is laid down being at least equal to the speed of the tubing before it enters the bending device. During the laying of the first turns of the coil the tubing is advanced at a greater speed than that at which the remaining turns are laid to counteract the effect of centrifuging force acting upon the turn being laid. During the bending operation the cross-section of the tubing is preferably reduced. The tube mill 1 is followed by a deflector 2 for directing rolled tubing to one or other of two roller tables 3 each table leading to cooling beds 4. Tubing directed to one of the tables 3 is intercepted by a duct 5 after it has been lowered and conveyed by a pivotable guide track 6 to the bending device 7. The roll stands of the bending device are preceded by driving rolls and the bent-tubing is fed obliquely downwards into a rotary coiling bin 8. The speed of the tubing as it enters the deflector 2 is detected by a tachometer wheel 12 which is used to control the drive of the bending rolls or of the separate driving rolls and of the rotary bin. The roll drive speed is approximately 10% higher than the speed at which the tubing leaves the mill. The first pair of bending rolls have grooves which do not completely surround the tube; the second roll stand has three rolls with grooves of a larger radius of curvature than that of the tube and the third roll stand over has three rolls with grooves which completely surround the tube (Figs. 8, 6, and 7 not shown). When winding a coil of spiral form the bending triangle formed by the roll stands is varied and the bending device traversed radially of the coiling bin. The speed of the rotary coiling bin is also controlled by a sensor which measures the diameter of turn instantaneously being laid or by a pre-determined control programme.

Title: Process of colour photography
IPC: G03C1/485
Filed: 1934-12-04
Abstract: 451,347. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Dec. 4, 1934, No. 34842. Convention date, Dec. 6, 1933. [Class 98 (ii)] In producing multicolour photographs, silver halide emulsion layers are used which have been fogged to such a degree that they yield directly a positive by development which ordinarily would yield a negative, such as the layers described in Specification 405,642. The layers may be colour-sensitized, and also may be coloured. In examples, component colour-records produced on panchromatic layers through selection filters are developed by colour developers and superimposed, or are developed by a tanning developer and etched to form dye-printing relief-matrices. The records may be formed on coloured layers and treated by known processes which destroy the dyestuffat the places where silver is deposited, as, for example, by forming at the places where silver is deposited an oxidizing body such as silver bromate and treating it with an acid solution of a vanadium salt as described in German Specification 396,485 ; or by reduction with sodium hydrosulphite ; or by Crabtree's process in which the silver picture, coloured with an azo-dyestuff, is treated with an acid fixing bath. The several layers may be on stripping supports which are all removed when the components are superimposed. Instead of exposing the layers separately, they may be exposed in known tripack form, and a tripack may be used for the direct production of printing matrices from multicolour screen pictures. A screen original, such as a lenticular screen picture, may be reproduced on such layers by printing each layer with a source of light not necessarily that corresponding to the colour sensation recorded in the layer, but adapted to the colour-sensitivity of the layer, as described in Specification 375,338. A sound record may be added on the same support by the same or a different process.

Abstract: 945,682. Starting prime movers. C.A.V. Ltd. Sept. 23, 1960 [Oct. 15, 1959], No. 34928/59. Heading H2H. Immediate reconnection of an engine starter motor 18 by a further operation of a switch 15 after the first operation of that switch has failed to start the engine, is prevented by the inclusion of a capacitor 14 in series with a winding 11 of a relay controlling contacts 10 in the feed path of an electromagnetic starter motor switch 16, 17, the capacitor being provided with a rapid charge path through a diode 19 and a slow discharge path through resistors 13, 20, and being of such a value that a predetermined time interval must elapse between the release of the switch 15 and its re-operation before the initial current flow through winding 11 is again sufficient to close the contacts 10. The resistor 13 permits sufficient current to flow through the winding to maintain the contacts 10 closed once the capacitor 14 has charged up. A relay 22 connected to a dynamo 23 driven by the engine is provided to open the starter circuit contacts 21 when the engine has reached a predetermined speed, but its operation can be prevented by additional winding 24 if starter relay current is still flowing.
