Title: Apparatus for winding helical wire grids for electron tubes
IPC: H01J19/00
Filed: 1960-02-22
Abstract: 938,431. Winding grid electrodes; brazing. RADIO CORPORATION OF AMERICA. Feb. 22, 1960 [March 9, 1959], No. 6188/60. Classes 83 (2) and 83 (4). Grid winding apparatus for manufacturing helical wire grids having portions wound at different pitches comprises a grid support, means for helically winding a wire at a constant turns per minute rate around said grid support, means for advancing the grid support at a plurality of  predetermined speeds, and presettable counting and switching means for determining the distance of grid support advance for each of said plurality of speeds, for automatically switching from one grid support speed to another, and for continuously cyclically repeating a pre-selected order of speed changes. To wind grid wire 24 on a mandrel 13 to form different pitch sections 14, 16, 18, 20 the mandrel is advanced at different speeds for the different sections, the rotational speed of the winding head remaining constant. The mandrel 13 is mounted on a carriage 30 advanced by a lead-screw 32 driven by a normal winding motor 34, a strip winding motor 36 and a band winding motor 38 individually coupled to the lead-screw 32 through trains of different ratios. The motors run continuously and simultaneously and operate through magnetic clutches actuated by switches in revolution counters 40, 42, 44, 46, driven from the lead-screw 32 which determines the number of turns wound for each section 14, 16, 18, 20, respectively. The de-energization of one counter, after a predetermined number of turns of a particular pitch have been wound, by a cam disc therein, energizes the next counter and actuates the appropriate electromagnetic couplings so that another motor drives the leadscrew for the next predetermined number of turns. A winding head 29 driven from the  motor 34 carries a reel 112 of grid wire 24 which passes over a pulley 138 and guide-pin 139 on the head 29 to be wound around the mandrel 13 as it advances through the head. Side rod wires 22 for the wound grid are fed through tubes 142 to the mandrel 13. If the rods 22 are to be disposed outside the winding 24, Fig. 1, the wire 24 is wound on the mandrel 13 in a first pass through the machine, and the rods 22 laid thereon and held in position by a securing wire 23 wound thereover in a second pass through the machine. Alternatively two winding heads 29 may be provided, the first head laying the wire 24 and the second head the side rods 22 and the winding 23. The completed grid stick, Fig. 1, is heated to braze the wire 24 to the side rods 22, the securing wire 23 is removed and then cut to units 12 by severing the sections 20.

The examples describe the addition of phosphorous acid, pyro-phosphoric acid, tributyl phosphite, phosphoric acid, triphenyl phosphite, trimethyl phosphate and triphenyl phosphate to polyamides derived from polymerized linoleic acid and diethylene triamine.
Patent GB-694599-A (GB)
Title: Improvements in and relating to a method of extruding chocolate and the like and a device for extruding chocolate and the like
IPC: A23G3/02
Filed: 1951-03-19
Abstract: 694,599. Feeding viscous chocolate, toffee and like material into open moulds. AKTIESELSKABET TOMS LABORATORIUM. March 19, 1951 [March 27, 1950]. No. 6493/51. Class 87 (ii). When extruding chocolate, cream, toffee and similar viscous masses through nozzles into open moulds the sprue or thread, formed upon the termination of each extrusion period between the mass in the mould and the nozzle, is caused at the end of the extrusion period to be engaged by a rotating member for winding the sprue or thread so as to tension it beyond its breaking point. The moulds 15 pass in succession under the discharge apparatus 1 which has a nozzle assembly 12. After the chocolate or other material has been discharged into a mould a string of it tends to be left between the mould and the nozzle and this string does not readily break, owing to its viscosity, and may result in waste material lying over the edge of the mould and getting in the way. It is the object of the rotating member 17 to prevent this. With the parts disposed as shown in Fig. 1 chocolate from the hopper 3 fills two cylinders 6 as their pistons 7 are retracted. A rotating vane 5 then places the cylinders 6 in communication with an outlet 10, through a passage 8 in the vane, and at the same time a member 13 carrying the nozzle 14 is moved to bring the nozzle to its discharge position (shown in dotted lines) where it communicates with the outlet 10; a clear passage is thus formed for discharge of the chocolate on the forward stroke of the pistons 7. After discharging the chocolate the nozzle is moved back, in the direction of travel of the moulds, and its outlet passes close to the shaft 17, which rotates at a relatively high speed in the direction 19. The rotating shaft, engaging the remaining string of material as it is being drawn out, causes it to wind itself on the shaft and break off. The material is scraped off the shaft by the edge of a pan 20. into which it falls. In a modification the nozzle 10 is fixed and the shaft 17 is journaled at the ends of pivoted arms which bring it up to the remaining string of material at the nozzle outlet as the discharge ceases, the shaft rotating continuously, or only when required e.g. by engagement with a friction wheel. In another modification both the shaft and the nozzle may be movable. In a further modification the shaft may move across the nozzle from one side to the other. In yet another modification the positions of both the nozzle and the shaft are fixed and the required effect is obtained by mounting the nozzle at such an angle and relative position to the shaft that the chocolate, while being discharged, misses the shaft but at the end of the discharge, when the material is no longer being forced out, the remaining viscous string hangs from the lip of the nozzle and in that condition encounters the rotating shaft and is wound on it. Where there are several nozzles in a row a single shaft, parallel to the row, may be used.
