Abstract: 1,086,851. Feeding sheets. WILLIAM CROSLAND Ltd. Aug. 20, 1965 [Aug. 21, 1964], No. 34218/64. Heading B6B. Sheets 17 are carried through a press such as a printing, cutting, or creasing press, by impaling pins -16 attached to -fingers 15 mounted on bars 12 carried by intermittently actuated endless chains, each bar 12 being registered, when a sheet carried thereby is located in the press, by two vertically - reciprocated pegs 32, Fig. 1a, or 54, Fig. 4, engaging recesses in the bar 12. Each bar 12 is also registered in the manner described before the sheet enters the press and also when the sheet is located over a delivery stack. All the pegs_32 are raised by the action of a cam 27 on a linkage 18, 20, 21, 22, and are lowered by the pressure of a spring 25 mounted on an extension 23 of link 22; this arrangement prevents damage to the mechanism if the downward movement of the pegs is obstructed by e.g. a displaced bar 12. The bars 12 are mounted in brackets 11, Fig. 2b (not shown), on the chains with some play in the direction of feed and transversely thereto. Further, the recess engaged by the tapered end of one of the pegs 32, is a good fit on the peg so ,as to register .the bar transversely In the arrangement shown in Fig. 4, the pegs 54 are fixed to a bar 52 reciprocated vertically by a cam-and-link mechanism as already described but arranged so that the pegs 54 are in their lowered or registering position just before the bar 12 reaches that position. Magnets 53 on the bar 52 act upon magnetizable strips on the bar 12 to draw the pins 54 into recesses 51 in the bar 12.

Patent GB-432407-A (GB)
Title: A method for the production of flexible insulation on electric conductors from polystyrol cellulose derivatives or similar substances
IPC: H01B3/44
Filed: 1934-12-04
Abstract: <PICT:0432407/IV/1> Wires and similar electric conductors are insulated with threads or bands of polystyrol, a cellulose derivative, or similar substance, by extruding a bundle of fine threads or bands from a press, carrying the bundle and the conductor through a stranding nipple or analogous device, and thence over a draw-off device to a winding appliance, and stranding the threads or bands together around the conductor by the relative rotation of the draw-off and winding devices with respect to the extrusion orifices. To avoid twisting of the conductor, this may be drawn from a supply drum which is maintained stationary or rotated with respect to the stranding axis in common with the winding device.  Openwork or closed insulations on the conductor are obtained in accordance with the selected number of threads in the bundle.  The conductor may be carried through the extrusion press and in this case the passage should be sufficiently wide or a cooling device should be provided in order that the conductor may be at the same temperature as the threads when it contacts with them.  The threads may be stranded in several superposed layers.  The stranded structure may be shaped by grooved rollers.  As shown, a bundle 2 of fine threads is extruded from a press 1, and the threads are carried through guide holes in a distributer disc 3, and thence to a stranding nipple 4.  A copper conductor wire 5 is drawn from a supply drum 6, carried through a passage in the extrusion press, through the distributer disc and thence to the stranding nipple 4.  The conductor and the bundle of threads are carried together to a drawing drum 7 and then to a winding drum 8. The draw-off speed is preferably greater than that of extrusion so that the threads are stretched.  The stranding nipple 4, drum 7, and drum 8 are arranged in a frame 9 which is rotated about the stranding axis and is positively coupled with the supply drum 6 so that the conductor is rotated at the same speed as the frame and is not twisted.  The threads are thus twisted about the conductor. If desired, the frame 9 may be stationary, the twisting being effected by rotation of the extrusion press or the disc carrying the extrusion orifices.  The Specification as open to inspection under Sect. 91 comprises also the stranding of extruded threads about each other, the wire core being omitted.  This subject-matter does not appear in the Specification as accepted.

Title: Heater and thermostat control assembly
IPC: F24C15/10
Filed: 1958-10-31
Abstract: 864,735. Electric hot-plates; drip pans. HART MANUFACTURING CO. Oct. 31, 1958 [Nov. 1, 1957], No. 35050/58. Classes 39(3) and 126. [Also in Group. XIII] A structure for supporting a heating unit 22 for pivotal movement between a raised and a lowered position carries a temperatureresponsive element 36 for pivotal movement relative to the heating unit in the direction of pivotal movement of the latter, the thermal element 36 being disposed normally for engagement with a vessel supported on the heater. Thus a spiral electric sheathed wire heater 22 forming a hot-plate is mounted in an aperture in a range top 10 for pivotal upward movement about a pivot pin 56, and a liquid containing thermal element 36 normally located in a central opening in the hotplate is supported by arms 72 also hinged on the pin 56, so that after raising the heater 22, the element 36 may also be pivoted up independently by a spring. A spring clip 51 has a top part 52 bent over ribs 50 of an upwardly bent part 46 of the top of a flange 13 of the aperture in the range top 10, a bottom lip of the clip being hooked under the rim 13. The clip has two downwardly extending arms 54 carrying the pivot pin 56. Arms 58 pivoted on the pin 56 extend towards the centre of the hot-plate and have arcuate portions 62 to which is secured a cylindrical shield 63 around the thermal element 36. Radial arms 60 extending from the arcuate portions 62 with an auxiliary strip 65 extending from the shield 63 form a spider supporting the heater 22. The lower outer edges of the spider rest on the top of a drip pan 16 resting on a flange of a trim ring 14. Between the arms 58 are two curved arms 66 pivoted at one end on the pivot pin 56 or adjacent thereto, the other end of the arms being joined by a web 68 with a bracket 70 carrying spring arms 72 supporting a connector 42 extending into the thermal element 36. A capillary tube 44 passes through the connector 42 into the element 36, which comprises a pair of telescopically engaged cups 38, 40 spaced to form a chamber 39 for a thermo-expansible fluid operating a thermostatic switch controlling the heater. One arm of a pre-loaded coil spring on the pin 56 is attached to an arm 54 and the other end to an arm 66 so that the arms 66 are urged up, the upward movement of the element 36 above the heater being limited by the entry of bracket 70 into a slot 74 in the shield 63. The heater can be lifted clockwise manually and the thermal element 36, which is moved up by the spring, may then be moved counter-clockwise for cleaning the shield 63. The capillary tube 44 may be coiled at 80 around the pivot 56. A safety switch 84 on the clip 51 has an actuating plunger 86 engaged by the ends of the arms 58 of the spider, so that when the heater and spider are pivoted up, the current supply is disconnected.

Abstract: 888,035. Making valve grids; soldering. SIEMENS & HALSKE A.G. Oct. 16, 1959 [Oct. 16, 1958], No. 35083/59. Classes 83 (2) and 83 (4). In making a crossed-wire grid for a thermionic valve a first layer of parallel wires is soldered to a second layer of parallel wires by a solder consisting of a titanium alloy. In an embodiment the wires of a first layer of parallel wires are coated with titanium and on them is wound a second layer of wires coated with copper or nickel. A nickel or copper coated tungsten ring is laid on the titanium coated layer and the assembly is heated to form an alloy of titanium and copper or nickel to solder the cross-over points of the wires and to solder the wires to the tungsten ring. The tungsten ring may alternatively be coated with titanium and placed on the copper or nickel-coated wire. In a modification, a first layer 1 of parallel titanium coated wires is wound, a foil 2 of nickel is placed on top and caused to hang down between the wires by winding a molybdenum wire 3 between the wires. A second layer 4 of parallel titanium-coated wires is wound on and the grid is heated and a titanium nickel alloy is formed to solder the wires of the first and second layers at their crossing points and to solder a grid carrier 5 to the wires. After soldering the remaining foil is removed in an air current by sanding or pickling. The wires may alternatively be nickel coated and the foil of titanium. The use of tunsten grid wire is referred to.
