Filed: 1970-05-01
Abstract: 1314902 Producing films of polymeric material M E WALLIS 1 May 1970 [2 May 1969] 21125/70 Heading B5B [Also in Division B8] A lay-flat film of thermoplastic polymeric material particularly useful in packaging food products by "curtain coating ", that is, a process wherein the products are moved through a sheet of the material as it issues from a nozzle as a viscous liquid so that the product surface is covered by the material which then cools and solidifies to form an impermeable cover, is produced by heating the material to the viscous liquid state, applying substantially constant fluid pressure to the viscous liquid thereby discharging the pressurized liquid from a nozzle in the form of a planar, continuous, steady, unbroken sheet and cooling the material so that it becomes a solid film which, in the particular use, overlies the food product. As shown, the apparatus consists of a melting vessel 24 enclosed in a jacket 28 surrounded by a coil 30 of aluminium tube, all enclosed in an insulating casing 32, and a similarly constructed pressure component 22 consisting of a vessel 34, jacket 38, coil 42 and casing 44. Both vessels 24, 34 are heated by air circulated by a blower 46 and heated at 48. An inert gas such as CO 2  or nitrogen from a cylinder 96 is preheated in coils 30, 42 and selectively admitted at the top of each respective vessel to pressurize the contents thereof. The vessel 24 is loaded with thermoplastic material through a top cover 62 and the material is melted therein. Pressurization of the vessel causes the hot viscous plastic liquid to flow through filter 64, conduit 70, filter 72 and conduit 74 into vessel 34 to fill it to a level determined by a control 94, whereupon a liquid inlet valve is closed and the vessel 34 is pressurized, causing the hot liquid to pass through a conduit 88 to an extrusion nozzle 14. The liquid issues from the nozzle as a continuous film on to a heated roller 16. A conveyer 12, Fig. 2, passes articles through the film so that they become covered with plastic material, surplus material being removed at 18 to be reused.

Title: Improvements in or relating to circuit-arrangements for generating alternating voltages from direct voltage source
IPC: G06V10/75
Filed: 1948-08-11
Abstract: 651,046. Converting. PHILIPS ELECTRICAL, Ltd. Aug. 11, 1948, No. 21134. Convention date, Aug. 14, 1947. [Class 38 (ii)] [Also in Group XL (c)] A circuit arrangement for generating A.C. from a D.C. source comprises a series combination including a condenser 1, an inductance 2 and the inherent circuit resistance represented by 3 which combination is periodically connected to the D.C. supply 4 and then disconnected therefrom, during which time the condenser is short-circuited. According to the invention the periodic connection and disconnection is effected by means of gas discharge tubes (see Class 40 (vi)), but in an embodiment according to Fig. 3 (which embodiment forms no part of the invention, a vibratory switch 5 is shown instead of the gas discharge tubes. The condenser 1 charges by way of a rectifier device 6 and contact 8 and discharges by way of contact 9 and another rectifier device 7. The voltage follows the full line portions of the damped oscillatory curves c, d, the rectifier devices preventing the currents i1, i2 from flowing in the opposite directions and thus the voltage remains at the maximum positive or negative values +v1 or -v2 until the switch arm has changed position. The cycle is then repeated to produce an alternating voltage wave, the frequency of the switching wave determining the A.C. frequency, which frequency may be much lower than the natural frequency of the series-combination. The circuit may thus be designed to have a high Q factor.
