Title: Irradiation of Dielectric Tapes and the like
Inventor: JOHNSTON ROBERT BURAN
IPC: B01J19/08
Filed: 1967-07-20
Abstract: 1,195,442. Polycarbonate films. GENERAL ELECTRIC CO. 20 July, 1967 [11 Aug., 1966], No. 33487/67. Heading B5B. [Also in Divisions G6 and H5] Radiation damage tracks are produced in a tape, i.e. a strip, a sheet or a tape, of dielectric material e.g. a 1000 foot length of crystalline polycarbonate tape, by moving the tape continuously through a zone subject to irradiation by collimated fission fragments. Thus in a chamber 11 are positioned pairs of plates 22 and 24 of fissionable material which produce fission fragments when exposed to a neutron flux. Tape 20 is arranged to travel from feed reel 14, between the plates via guide rollers 27 and back to takeup reel 15, the tape being driven by capstan 17. Collimators 30, 31, 34 and 35, comprising a large number of closely spaced aluminium strips, serve to direct the fission fragments at the tape 20. The tape speed may be regulated, is preferably constant and is chosen together with the neutron flux used so that the density of the damage tracks in the tape is substantially uniform. The chamber 11 may be attached to a source 39 of helium under pressure. The chamber 11 may be positioned in the centre of a nuclear reactor which provides the desired neutron flux in which case the drive 17 and the feed and take-up spools 14, 15 are positioned in a chamber 10 placed outside the reactor. As seen in Fig. 3 the irradiated tape may be fed from spool 15 through an etchant bath 44, e.g. 6N.NaOH for a time sufficient to remove the material defining the damage tracks and form apertures, e.g. of opening size 5 to 100,000 , in the tape, the tape then being water rinsed in tanks 50, 51, dried with hot air in box 53 and finally wound on reel 56 as a finished product. The liquid 44 is kept at the correct temperature by heater 45 and thermostat switch 46.

Abstract: 865,019. Transformers. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 23, 1958 [Oct. 30, 1957], No. 33937/58. Class 38 (2). One or both of the windings of a high-voltage transformer consist of a number of coils 18, 19, 20 in series, each coil being divided into two or more layers 14 of conductors with an oil duct 17 between them, the spaces between the coils and surrounding them being filled up with solid insulation to exclude pockets of dielectric liquid. The coils 18, 19, 20, which are connected at their lower ends, may diverge as shown in Fig. 1 so that the amount of separation is proportional to the voltage gradient between them. The conductors in the layers forming a coil may be transposed at the centre 21 to avoid circulating eddy currents. The solid insulation between the low-tension winding 15 and the high-tension winding 18, 19, 20 may be of U members and bevelled sheets of press-board and the leads may be taken out through insulating channels 54 (Fig. 9). The voltage gradient at the edges of the coils is reduced and concentration of electrical stress is prevented by the use of edge strips composed of conductors 26 (Fig. 7) surrounded by enamelled wire and paper insulation. To protect against surge voltages static plates consisting of metal foil washers 35 (Figs. 4 and 5) between pressboard washers 34, 37, are provided and may be edged with tape 36. A core shield 51 (Fig. 1) composed of copper foil 48 between insulating sheets 49, 50 may be wrapped round the core and a similar shield 52 may be arranged between the H.T. and L.T. windings.

Abstract: 411,163. Dressing poultry; cooking flesh in oil. ASHBY, W. R. C., Fen Pond Farm, Ightham, Kent. Dec. 3, 1932, No. 34319. [Classes 28 (i) and 28 (ii).] Pieces of meat, or the flesh or carcases of chickens or other birds, are cooked prior to canning by contact with hot oil, e.g. groundnut oil, and air or oxygen is excluded from the food during the cooking. The oil may be sprayed or poured on to the food, and the air is excluded by the presence of an inert and innocuous gas such as carbon dioxide. As shown, carcases of chickens held in trusses as described in Specification 411,508 and suspended from a conveyer 23, slide up the shoot 30 and over a guide plate 39, from which they swing downwardly into the heated oil contained in the tank 32. Carbon dioxide is supplied from bottles 132 of compressed or liquefied gas, the gas bubbling from a submerged pipe 38 and collecting above the oil surface in the chamber 31. The air in the carcases is replaced by carbon dioxide, and, is together with air drawn through the restricted entrance between the guide 39 and the casing of the chamber 31, led away through the outlet 40. After passing through the cooking-oil, the carcases ride up the shoot 41, over a trough 42, which receives the oil draining from them, and into a washing-tank 43 containing water heated by a steam coil 44. The oil is heated by an oil-burner 130, and the scum from the washing-tank is led away through a pipe 50 to a tank 51. The conveyer 23 is trained around horizontal sprockets to rim in a horizontal plane, and the cooking and washing tanks are in a room, the conveyer passing into and out of the room through swing- ing trap doors. As the cooked carcases emerge from the room they are removed from the conveyer and the trusses are removed from the carcases. The carcases are then inserted in cans or other containers which are charged with gelatinous solution, exhausted of air, sealed, heated in retorts to complete the sterilization and then cooled. In the treatment preparatory to cooking, the carcases are carried on an endless band conveyer past stations where the operations of neck slitting, decapitating, leg cutting, gland removing, eviscerating, cleaning and trussing are effected. The neck slitting is effected by an operator holding the neck in stretched condition against a rotating disc knife, the neck being slit slantwise to facilitate the formation of a flap which is subsequently used to close the neck opening. A second operator holds the neck stretched under a decapitating guillotine, a third operator removes the legs just below the hocks by a guillotine, and a fourth operator removes the oil gland. A fifth operator removes the viscera by the device described in Specification 411,164, and the sixth and seventh clean the carcase and apply the truss respectively. The trussed carcase is then hooked on to the cooking-conveyer.
