Abstract: 1534653 Electroradiography AGFA-GAVAERT AG 11 March 1977 [12 March 1976] 10431/77 Heading H5R In a radiographic recording process, a change image is produced on a layer of thermoplastic dielectric material 6 located between electrodes I and 2 in a chamber 5a filled with an X-ray absorbent gas at greater than atmospheric pressure, by exposing the chamber to X-rays through the object 7 to be examined; heating the layer to a temperature above its softening point to form a relief image; and rendering the relief image visible by projecting a light beam therethrough. As described, the layer is heated by a heater 9 within the electrode 2 against which the layer is mounted; the layer is thus transported by rollers 11, 12 into a communicating chamber 5b having transparent walls through which light from source 17 is directed, the resulting optical image being received on a screen 20 or on a light-sensitive recording member 26. During return to the chamber 5a, the layer passes an energized corona discharge device 13 which neutralizes the change image, subsequent heating of the layer by the heater 9 erasing the relief image such that the layer is again ready for use. The X-ray absorbing gas may be Freon (R.T.M.), Krypton or Xenon at 6 to 20 atmospheres pressure.

IPC: H01G13/00
Filed: 1964-03-12
Abstract: 1,063,282. Casting processes; casting electrical terminations on capacitors. WESTERN ELECTRIC CO. Inc. March 12, 1964 [March 25, 1963], No. 10448/64. Heading B3F. [Also in Divisions B5, G3 and H1] End portions 21 of various forms are cast on electrical capacitors 22, Figs. 7, 9-17, 33 and 34 (not shown), e.g. having interleaved layers 23-26 of conductors and dielectric, by forcing solder into mould cavities 72, e.g. in mould plates 71, Figs. 1-5 and 18-28 (not shown), moved to abut or encompass the capacitor ends, and into spaces. between the layers 23-26, Fig. 7 (not shown). The mould may be of synthetic resin and the end of a capacitor may be forced into solder in a mould cavity to force the solder into the capacitor spaces. In one form of apparatus, Figs. 1-6 (not shown), a succession of capacitors 22 are clamped in turn between one fixed and one reciprocable jaw 31 and 32, Fig. 4 (not shown), while two stainless steel mould plates 71 (which may have auxiliary cooling) are moved against either side of the closed jaws, Fig. 3 (not shown), together with lengths of lead wire 83 to be embedded in the cast ends 21. The jaws may have knock-out pins. Shanks of terminal pieces (instead of lead wires) may be embedded. Reservoirs 52 of molten solder 48 and solder-injecting nozzles 73 move with the plates 71 and the lead wire may be preheated and precoated in the reservoirs. The lead wire 83 may be precoated with a different material in a separate bath, Fig. 18 (not shown). The solder may be injected by gas pressure or plunger. Solder wires 124 are fed automatically to the reservoirs 52 when required to maintain the metal level (see Division G3). If an elastic membrane 183 or an 0-ring 184, Figs. 21, 22 (not shown), is used to seal round the capacitor end when casting, there need be no clamping jaws 31, 32. The mould cavity 72 may be variable, Figs. 23, 24 (not shown), two side members 188 being movable towards one another in a slot 189 in the plate 71. To form an annular end 21, Fig. 17 (not shown), concentric annular knife edges 191, 192, Figs. 25, 26 (not shown), may project from the plate 71 to penetrate the capacitor end. In Fig. 30 (not shown), air is drawn out of the capacitor 22 by a plunger 395 before solder is injected into the mould cavity 372. In Fig. 31 (not shown), there are no mould plates and the mould cavities 472 are formed in clamping jaws 431. In Fig. 32 (not shown), there are no clamping jaws and two mould plates 571 periodically abut face-to-face to form two cavities which accommodate in succession the whole of each capacitor. Solder is fed to the two adjacent ends of the aligned cavities so that a leading end of one capacitor and a trailing end of the preceding capacitor of a series are cast at one time. The terminations are formed with electrical and mechanical connections, Figs. 33, 34 (not shown), so that no leads 83 are required.

Abstract: 1,123,824. Heating resistances for packaging machines. A. SCHMERMUND. 16 Feb., 1966 [13 March, 1965], No. 10746/65. Heading H5H. [Also in Division B8] In a packaging machine in which superposed or overlapped portions of wrapping material are glued or heat sealed together, the wrapping material is heat sealed or the glue dried by contact with a heated wall or wall portion of a guide passage. The wall or wall portion is made of electrically conductive material and heated by passing current through it, slots or perforations being provided in the wall or wall portion to increase its electrical resistance. As shown, a cigarette packaging machine includes a guide passage 5, Figs. 1 and 5 (latter not shown), through which packets (23) of cigarettes are pushed by a reciprocable member (22), a pusher (25) removing them laterally as they emerge. The passage 5 comprises four walls 1-4 of which the walls 2-4 are heated and each comprise a sheet of metal backed by a heat-resistant supporting carrier 6, with an electrically insulating layer 7 separating them, the layers being connected together by electrically insulated rivets 8, or glue. The carrier 6 may be made of metal or of an electrically insulating material, e.g. ceramics or heat resistant plastics, in the latter case the insulating layer 7 may be omitted. The metal sheets 2-4 are electrically connected by metal strips 11, 12 screwed to lugs 13 of the walls. Similar lugs 14 serve as terminals for the walls 2, 4. The fourth wall 1 is mounted on levers (24), Fig. 5 (not shown), so that it may be pressed against the packets. In one embodiment, the electrical resistance of the sheets 2-4 is increased by an arrangement of slots 19, 16, see also Fig. 2 (not shown), and perforations 21, the slots extending parallel to the sides of the sheets. In a modification of this, Fig. 6 (not shown), parallel slots (119), (116) are arranged at an angle to the sides of the sheets. In a second embodiment, Fig. 8 (not shown), the carrier (206) is provided with a zig-zag groove (226) into which a continuous strip (227) of electrically conducting material is cemented. The strip (227) thus forms a wall having slots (216), (219). In another embodiment, Fig. 10 (not shown), the carrier (306) is coated e.g. galvanically with a metallic coating (327), e.g. of chromium, parallel slots (316), (319) being provided in the coating, e.g. by etching. In another embodiment, Fig. 18 (not shown), a wall (502) is provided with perforations (532), the wall being a metal sheet or a coating. In another embodiment, Figs. 12-17 (not shown), a wall is provided by a strip (427) which is bent to form parallel runs connected at the ends of the runs by bending the strip as at (430), Fig. 17 (not shown). Parallel slot-like gaps (431) are thus formed between adjacent runs of the strip.
