Title: Improvements in or relating to mountings for coil assemblies for television and other cathode ray tubes
Inventor: HALLAM TERENCE WALTER
IPC: H01J29/82
Filed: 1954-06-23
Abstract: 783,781. Electron beam focussng and deflecting apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 3, 1955 [June 23, 1954], No. 18484/54. Class 39(1). A coil assembly of a cathode ray tube has a mounting comprising a frame structure 1, 2, a carrier member 7 for the coil assembly, the carrier being supported from the frame with free but limited movement in any direction in a plane perpendicular to the axis of the coil so that when the tube is operatively positioned with respect to a mounting, the tube is fixed relatively to the frame structure and the neck co-operates with the coil assembly any eccentricity of the tube neck with respect to the tube as a whole being accommodated by movement of the carrier in said plane. As shown, the mounting device for the focusing and deflecting coil assembly comprises four rings of which 1 and 2 constitute the frame and coil carrier 7 has holes 10 for screws for attaching the coil assembly. The coil carrier 7 has three grooves 12 on its underside co-operating with three grooves 13 in the upper surface of ring 8 from which they are spaced by balls 14, and the underside of 8 and the upper surface of 2 have similar grooves at right angles to the previous set also provided with balls 17. Rings 1 and 7 are just out of contact, this being achieved by correct insertion screws or bolts 5 into tubular spacers 6. The coil assembly passes through the control holes in rings 8 and 2. When the tube neck is inserted into the coil assembly, the neck eccentricity, if any is taken up by the floating mounting of 7 and 8. The above arrangement is adequate if the cathode ray tube is mounted vertically. If, however, the tube is mounted horizontally instead of vertically ball bearings may be required between 1 and 7, e.g., 1 and 7 may each have three shallow circular recesses with balls. It is also necessary in this case to provide a counterpose for taking the weight of the coil assembly and of ring 7 such as a counterbalance weight or spring attached to ring 7. In one example an adjustable spring is attached to ring 7 and to a fixed part of the framework, the spring being adjusted so that the coil assembly is mechanically " floating."

Abstract: 890,213. Making grids for electron discharge devices; brazing. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 11, 1958 [June 18, 1957], No. 19117/57. Classes 83 (2) and 83 (4). A method of making a grid includes the steps of winding grid wire on a grid support which is provided with notches each having an inclined side so that during winding the wire engages said inclined sides and passes therealong into the apices of the notches so that the angle at which the wire is disposed relatively to said support is determined by the disposition of said apices, and thereafter joining said wire to said support. A molybdenum frame 1 has a punched or etched series of notches 2, 3 in opposed edges, the apices of the notches 2 being in line with those of the notches 3 so that when the frame is wound with wire in a conventional winding machine the wire slides into the apices and the resultant wound grid has a series of parallel lengths 6 of wire normal to the notched edges of the frame 1 and on the other side of the frame a series of parallel lengths 7 inclined to said edges. The wound wire is then secured to the frame by brazing and if desired, the wire lengths 7 removed. The wire may be of goldplated molybdenum or, after winding, the molybdenum wire and frame may be coated with gold, the assembly being heated in hydrogen or inert gas to cause the gold plating to braze the wire to the frame. The notches may be of V-shape with one edge normal to the edge of the frame. The grid wires 6 may be wound at an angle other than normal to the frame edges.

Abstract: 923,689. Sorting by weighing. ILLUMITRONIC SYSTEMS CORPORATION. May 29, 1961, No. 19374/61. Class 143. [Also in Group XXX] Articles are fed from a conveyer belt 12 via an endless conveyer 22 to one of three belts 48, 46, 50, according to whether the article is of normal weight, over-weight, or underweight, respectively. As each article interrupts a beam of light from a photo-electric device 11, it operates a switch 10 of a weighing device 8 of which the conveyer belt 12 is a part. If the article is over-weight or under-weight the switch 10 energizes respective solenoids 52, 54, so as to deflect a cable 66 in one direction or the other, thus deflecting either a. leaf-spring 76 or leafspring 78 respectively. The article being guided by rails 14, 14, and rollers 16 passes on to a respective carrier 34 which is capable of lateral sliding movement on rods 32 carried by chains 30, 30, of the conveyer 22. Each carrier 34 has downwardly-extending pins 44, 44, which when the leaf-springs 76, 78, are undeflected, pass on either side of them and permit the carrier 34 to proceed along the centre line of the conveyer 22 to the central conveyer belt 48. If the leaf-spring 76 has been deflected by the action of the switch 10, as shown in Fig. 8, the corresponding pin 44 of the carrier 34 passes on the inside of the spring 76 and causes lateral deflection of the carrier 34 so that the pin 44 is moved into engagement with the outer face of an angle-shaped cam member 80. With continuing movement of the conveyer 22 the carrier 34 is thus progressively deflected diagonally by the cam member 80 into a position in which it passes on to the belt 46. Similarly, under-weight articles are deflected by a cam member 82 to move diagonally across the conveyer 22 to pass on to the belt 50. The invention may be modified so that more than three paths, or even only two paths may be provided for the carriers. There may be two switches 10. Instead of being responsive to the weight of the articles the switch 10 may be operated in respect of their size or the degree of filling of containers. The carriers 34 are returned to their initial central position during the return run of the conveyer 22 by further angle-shaped diagonally disposed cam members similar to the members 80, 82.

Abstract: 1457580 Bobbin skewer N V SHETH 2 May 1974 [3 May 1973] 19409/74 Heading D1J The invention relates to a bobbin skewer of the kind comprising a tubular housing 20 that is tapered at one end 11 and has bearing means 22 at the opposite end, the axis of the bearing 22 extending transversely of the axis of the housing 20. An elongate camming means 6 in the housing 20 acts on dogs 12 that can extend outwardly through slots 23 in the tapered end 11. When the camming means 6 is raised the dogs 12 move outwardly to grip a bobbin received on the skewer. When the camming means 6 is lowered the dogs 12 move into the skewer to release the bobbin. According to the invention the end regions of the dogs further from the bearing 22 extend obliquely relative to the longitudinal axis of the skewer so as to extend simultaneously radially inwards and axially away from said bearing 22. This oblique part of each dog 12 assists the sliding of bobbins onto the skewer.
