Title: Method and apparatus for registering perforated films and for transferring photographic emulsion layers from one such film to another
IPC: G03C7/22
Filed: 1947-06-06
Abstract: 629,032. Colour photography. KODAK, Ltd. June 6, 1947, No. 14956. Convention date, July 13, 1946. [Class 98 (ii)] In a method and apparatus for registering accurately in intimate contact two perforated motion picture film strips and for transferring an emulsion layer from a perforated multilayer stripping film to a similarly perforated blank film, as for processing, means are provided for pressing the two film strips into intimate slidable engagement while they are in approximate registration and immediately prior to their being fed on to a carrier provided with registering fins, by which they are brought into accurate registration. The transferring apparatus, as shown, is of similar form to that described in Specification 574,164, but includes a pair of rollers 25, 26 for pressing the two films 10, 14 together within the liquid area of the tank 19 prior to the seating of the films by socket roller 28 on to the driven pin roller 27. Roller 25 is rubber covered, and roller 26 is flanged and urged to roller 25 by a spring 30 to provide the required pressure. An emulsion layer originally on film 10, where adhesion has been weakened by liquid in the tank 19, may thus be caused to adhere to the other film 14, and the two films, after passing round the pin roller 27 are removed therefrom by flanged roller 33, separated after passing between guide rollers 34, 35; dried in chambers 36, 37 and wound on take-up reels 38, 39. Specifications 574,137 and 582,438 also are referred to.

Title: Process of automatic arc welding using coated electrodes and device for use therewith
IPC: B23K9/14
Filed: 1939-05-19
Abstract: 608,484. Uniting by fusion. ELIN AKT.- GES. FUR ELEKTRISCHE INDUSTRIE. May 19, 1939, Nos. 15025 and 15026. Convention dates, Dec. 27, 1938, and May 8, 1939. [Class 83 (iv)] In a process of electric-arc welding with fluxcoated electrodes arranged parallel with the line of the joint, the electrode or the aperture end thereof is held in position on the joint by one or more bodies which form with the work a channel in which the electrode lies. A grooved bar 4 holds the electrode 3 against the joint between the work parts 1, 2. The bar may consist of metal, carbon or other electrically conductive material or of plastic material and may be insulated from the work or electrode, or both, by an inserted strip 5 of thermal or electrical insulating material which may be treated with deoxidizing materials or may consist of such materials. The layer may consist of paper. The face of the bar may also be coated with insulating material. T-joints between plates 1, 2, Fig, 3, may be similarly welded by a pair of electrodes 3. In another form, the bars may be replaced by a grooved roller 4 coated with insulating material, particularly for welding circumferential joints. The roller may be rolled along the joint at the speed of burning of the electrode or the work and electrode may be traversed relatively to the roller. The electrode may be of triangular or square section. The Specification as open to inspection under Sect. 91 comprises also a triangular electrode arranged so that the greatest cross-section is vertical. The electrode may be held by the bar &c. beyond the end of the joint so that welding may be effected right to the end of the joint. A number of electrodes may be placed in alignment and fused consecutively, the following electrode being ignited by the arc of the preceding electrode. A pair of aligned electrodes may be used with arcs started at the same time as the inner end of each. The parts 1, 2 may' be arranged as shown in Fig. 7 (Cancelled), so that the line which bisects the parts is vertical, the fused metal running into the joint by gravity. This subject-matter does not appear in the Specification as accepted.

Title: Braiding machine bobbin carrier
Inventor: OLSON ROBERT VALDEMAR
IPC: D04C3/14
Filed: 1957-05-13
Abstract: 836,239. Braiding machines. WANSKUCK CO. May 13, 1957, No. 15122/57. Class 74 (1). Yarn from a rotatable carrier bobbin B passes up over a first pulley 59 on a bracket 52 adjustably secured to one, 19, of three parallel posts, down under a second pulley 55, carried by a bracket 54 slidable on the two other posts 17, 18, and over a third pulley 28 mounted on a castor on a bridge 20 which locates the tops of the posts; and as yarn is consumed, the bracket 54 is pulled up the posts 17, 18, against the action of compression springs 57, 58 (which, when unstressed, are at least as long as the bobbin spindle 13) until the bracket engages the upper end 49 of a member 45 slidable on the post 19 and lifts it, against the action of a spring 51 so far that its foot 46 rocks a latch 38 to bring the far end 40 of the latch out of engagement with teeth 65 on the lower flange of the bobbin and the bobbin can rotate to yield more yarn. The castor bearing the pulley 28 can swivel about its vertical axis, under the action of the yarn, to bring the axis of the pulley parallel to the mutually parallel axes of the pulleys 55, 59. In order to provide as much room as possible for the bobbin and to provide the greatest possible clearance 67 between the bobbin of one carrier and the post 17 of another (passing) carrier, the post 17 is somewhat nearer the bobbin axis than is the post 18; and the centre of the pulley 55 lies midway between posts 17 and 18. The bobbin is secured endwise on its spindle 13 by a mouthed plate 34 swingable about the post 19 with a wire clip having resilient jaws 36 and a handle 37. An extension 42 of a boss 12 carrying the bobbin spindle forms a thrust abutment against which the free end 40 of the latch slides. Specification 836,240 is referred to.

Title: Improvements in portable pneumatic guillotine shears
IPC: A01G3/033
Filed: 1933-05-25
Abstract: 410,320. Guillotine shears for pruning and cutting hedges &c. FURSTOSS & LAGNIER, Rue du Commandant- Vidal, Cannes, France. May 25, 1933, No. 15161. Convention date, May 30,1932. [Class 6 (ii).] Portable pneumatic guillotine shears particularly for cutting or pruning trees and plants comprise a movable blade 1 actuated by at least one piston 11 movable in a cylinder 12 by gaseous pressure fluid. The blade 1 moves in slides on a counter blade 5 rigidly mounted on the frame and is in the form of a hook with a bevelled cutting edge 6. The blade 1 is connected to a piston rod 10. The cylinder 12 is formed with a platen 17 whereon moves a slide valve 16. By a series of ports 18, 19, 20 and conduits 21, 22, 23, pressure fluid from a pipe 26 may be delivered to the rear of the piston 11 or to the front of the piston for the return stroke. An auxiliary piston 13 may be provided on the rod 10 so as to move in a cylinder 15 connected to the conduit 23 so that fluid is conducted to the cylinder 15 for the return stroke. A port leading to the atmosphere may be provided at the top of the cylinder 12 ; the forward stroke is then effected rapidly. Alternatively, ports 27 may be provided in the wall of the cylinder so that a cushion of air at the top of the cylinder reduces the shock towards the end of the forward stroke. To prevent retardation of the piston on the return stroke, a valve 33 is provided in a conduit 32 leading to the atmosphere so that air may be supplied if a partial vacuum is set up in the top of the cylinder. The slide valve may be operated by hand for both strokes or it may be automatically operated by the piston for the return stroke. Shock at the end of the return stroke is avoided by the small cross-section of the piston 13 or by varying the cross-section of the port 20 by the slide-valve so as to control the fluid supplied to the cylinder 15, or by connecting the ports 18, 20 so as to use a portion of the compressed air operative during the forward stroke for the return movement. Shock at the end of the forward stroke may be reduced by resilient means such as springs. The blade 1 may be loosely connected to the rod 10, so that the latter acts as a hammer on the rear of the blade. Movement of the pistons may be controlled automatically by a device such as is used in pneumatic riveting machines.

Title: Improvements relating to machines for curling hair and the like
IPC: B68G3/06
Filed: 1929-05-16
Abstract: 323,995. Fitzpatrick, H. D., (Manufacturers Machinery Co.). May 16, 1929. Fibres, curling.-Hogs' and other hair &c., generally in short lengths, for cushions, pads, mattresses, pillows, &c., is curled by forcing it into tubes, wetting, removing, and drying it. The hair 11 fed into a hopper 10 is caught by fingers 15 carried on plunger 14 having bifurcated ends 16. The plungers are reciprocated and rotated by mechanism such as that shown; as the plungers advance they twist the hair and force it into tubes 13, and as they recede the rotation, which is reversed in direction, assists in extricating the plungers from the hair. The plungers are preferably of angular cross-section, the edges assisting in twisting the hair. Steam or vapour is passed to the tubes 13 through an opening 35 and exhausted through pipe 51. The hair extruded from the tubes is held between grooved reticulated conveyers 38, 39, whilst it is dried with the aid of heat and a fan 45.

Title: Stable pulse generator
IPC: H03K3/04
Filed: 1943-09-17
Abstract: 592,258. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Sept. 17, 1943, No. 15327. Convention date, Dec. 20, 1941. [Class 40 (v)] [Also in Group XXXV] A pulse generator comprises an inductance with a rectifier in shunt and connected to a source of periodically recurrent short duration current surges. As shown, a pentode T1 serves as a triode oscillator, but the suppressor grid is biassed below cut-off, so that class C operation results and only short current surges are derived from the output. The output is applied to an inductance L2 shunted by a rectifier T2 preferably in series with the resistance R3 to reduce the effect of the diode anode-cathode capacity. In this way high voltage pulses of short duration are produced and all voltage variations except the initial surge is eliminated. The width of the pulses depends on the damped oscillation frequency which would'be set up in the inductance in the absence of the diode so that the width is adjustable by varying the inductance, while, the frequency depends on the frequency generated by the circuit L1, C1. As shown, the inductance L2 is variably coupled to the inductance L3 and the frequency is determined by the circuit L1, C1, the capacity C1 varying the frequency. If a fixed frequency is required, a piezo-electric crystal may be used. The output from the inductance L2 is fed to a cathode follower T3, the load P1 being connected across the low magnitude, cathode resistance R4. A small coupling condenser C8 may be provided to avoid a heavy shunting of the pulse generating source. Time modulation may be obtained by varying a constant of the damped oscillation circuit, e.g. by varying the inductance L2 in accordance with the intelligence signal.

Abstract: 726,932. Feedwater heating systems; heating air. FOSTER WHEELER, Ltd. June 22, 1953. [June 20, 1952] No. 15615/52. Classes 64 (1) and 64 (3). In a feedwater heating system as described in Specification 674,583, the rate of flow of feedwater through the economiser section 24 most remote from the furnace is automatically controlled by the temperature of the feedwater or flue gases leaving that section, so that the temperature of the section is maintained above the dew-point of the flue gases. A thermostat 42 or 56 actuates a valve 44 admitting air to one or other side of a piston 46, which opens or closes either a valve 48 in the outlet from the economiser section 24 or a valve such as 60 controlling the supply of feedwater to the section 24. The valve 48 has a bypass 50 so that there is always some water flow in the economiser section 24. The water is heated by steam in two heat-exchangers 28, 32 before reaching the economiser. The part of the feedwater supplied to the section 24 is drawn off either between the two heat-exchangers 28, 32, as shown, or after leaving the second one. In the latter case it is cooled by heating combustion air before entering the section 24.
