Title: Improvements in the thawing of frozen fish
Inventor: JASON ALFRED CHARLES
IPC: A23B4/07
Filed: 1958-08-14
Abstract: The phenomenon of "run-away heating" in the thawing by R.F energy of deep-frozen blocks of animal matter such as fish may be avoided by determining the maximum permissible mean rate of R.F. energy input per unit mass (wmax) of a frozen block and passing blocks continuously and with minimum permissible spacing through an R.F. field at a rate (measured in terms of mass per unit time) which is calculated as the ratio of the product of wmax, the R.F. field, electrode length (l) in the direction of travel of the blocks and the width (b) and thickness (c) of a block to the enthalpy per unit mass of the block for a given input temperature; b, c and l should preferably be so chosen that all the available R.F. power (Wmax) is utilized at the electrodes, where Wmax=b.c.l.wmax Examples are given. The Specification also makes the following disclosures:-  (i) each block may contain discrete units of e.g. fish of comparable size; (ii) when the blocks are conveyed horizontally between vertically-spaced upper and lower electrodes, dripping of fluid on to the lower electrode may be avoided by supporting the blocks on trays or by encasing them in waterproof containers;  (iii) when a plurality of blocks are to be passed between the electrodes, arcing may be prevented by interposing thin layers of a material of high dielectric strength such as sheet polythene;  (iv) for thawing fish, the electrode width should be less than that of the blocks by two inches for blocks below about twenty inches width (but of the same width for those of thirty inches width or over);  (v) the R.F. energy should be fed to an electrode at its centre;  (vi) an earthed screening plate may be interposed between the blocks on the conveyer and the strip connecting the upper electrode plate to the oscillator;  (vii) the lower electrode should be bonded to earth;  (viii) the conveyer may be supported by a lower electrode plate coated with a thin layer of polytetrafluorethylene to minimize friction.

Title: A Method of Securing a Feed Conductor for Electric Current to Heating Wires of a Kind Suitable for Incorporation in a Laminated Panel
Inventor: HINTON BRIAN JAMES
IPC: H05B3/06
Filed: 1966-06-11
Abstract: 1,183,316. Soldering. TRIPLEX SAFETY GLASS CO. Ltd. 5 June, 1967 [11 June, 1966], No. 26126/66. Heading B3R. In securing a feed conductor for electric current to heating wires suitable for incorporation in a laminated panel, the wires are placed on an even surface, the feed conductor, which comprises a metal strip coated with solder, is placed across the wires and the feed conductor is heated by high frequency induction to melt or soften the solder. Tungsten wires 10 of diameter 0À0005 inch are laid on a sheet of glass 11 forming part of a transparent panel, e.g. for a windscreen of a motor vehicle or aircraft and are sprayed with a solution of resin in chloroform and a solder coated copper strip 12 of thickness 0-003 inch is laid across the wires so that it forms arches over the wires and lies against the glass sheet between the wires. An induction coil 13 mounted on a carriage 14 is moved along the strip to heat the strip and soft heat resisting, e.g., silicone rubber rollers 15 on the carriage press on the strip and assist in causing the solder to flow over the wires 10. When the solder is cooled it surrounds the wires which are embedded in it. An upper sheet of glass and an interlayer sheet are added to form the panel. In a modification after the strip has been laid on the wires on one sheet of glass, an interlayer is placed on them and an upper sheet of glass is placed on the interlayer. The assembly is then heated and subjected to pressure and the induction coil employed is mounted on a handle to be manipulated by an operator along the underside of the lower sheet of glass. The coil may be coated with a material having a low coefficient of friction to be slid along the glass. The wires and feed conductor may be joined together on one surface and then removed and placed elsewhere. The wires and feed conductor may be used in non-transparent panels.

Abstract: 402,218. Discharge apparatus. JENAER GLASWERK SCHOTT & GEN., Otto-Schott- Strasse, Jena, Germany. Sept. 21, 1932, No. 26212. Convention date, Sept. 22, 1931. [Class 39 (i).] In circuits for incandescent-cathode, gasdischarge devices in which an additional transformer h has its primary h<1> in the discharge circuit g and its secondary h<2> in the cathodeheating circuit opposing the voltage of the transformer windings e to reduce the heating current as the discharge current rises and so to keep the total heating of the cathode constant, the iron core of the transformer h is saturated when the discharge device is operating at full load so that, on the occurrence of overloads, the heating current cannot increase through an increase of the secondary voltage of the transformer h above the voltage of the windings e. Fig. 1 shows a 3-phase rectifier circuit using three single-phase rectifiers a each with an anode b and an indirectly-heated cathode c. In a single-phase circuit supplying a glowdischarge tube having two indirectly-heated electrodes (Fig. 2, not shown) the primary of the additional transformer is in the primary circuit of the transformer supplying the discharge current and may act as a ballast, whilst the secondary of the additional transformer is in series with the primary of the heating-current transformer and opposes the applied voltage. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which the heating circuits are fed from additional secondaries on the discharge-supplying transformer, a choke being connected in the primary circuit so that the heating voltage drops as the discharge current rises. This subject-matter does not appear in the Specification as accepted.

Abstract: 1317829 Fibrillating films SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 1 June 1970 [3 June 1969] 26217/70 Heading B5B In a process for the production of crimped fibres or filaments wherein a film obtained by the extrusion of a molten, molecularly-orientable, thermoplastic material through an annular slit is stretched and fibrillated or fiberized, the annular slit has one shaping wall which is in relative movement to the other shaping wall thereof. After stretching the film at a ratio between 1 : 3 and 1 : 20 and fibrillating or fiberizing by rubbing, beating, tearing, passage over a pinned roller &c. the fibres exhibit a crimp which is sufficient for some applications e.g. crimped yarns ar fabrics, the crimp being assumed to be the result of the orientation induced in the molten layer by the surface shearing forces induced as it is being extruded between the moving walls. For other applications, e.g. stuffing mattresses &c., heat insulating, production of non-wovens or felts &c., where a higher degree of crimp is required the fibres are subtracted to a short heat treatment with hot air or steam. The preferred starting materials are the homo and copolymers of lactones, especially polypivalolactone, and low pressure polyethylene and polypropylene. The extrusion head may conveniently have a rotating mandrel and a stationary barrel. In a preferred form the head has two or more concentric annular slits and a rotating mandrel and can have a contra-rotating outer barrel. The tubular film produced may be laid flat or cut open before the stretching &c., steps.

Abstract: 620,305. Coin-freed apparatus for delivering measured quantities of liquids. BERRY, D., and ELLIOTT, A. C. Oct. 9, 1945, No. 26274. [Classes 27 and 106(v)] [Also in Group XXVIII] In apparatus for dispensing small quantities of cigarette-lighter fuel after insertion of a coin, the return movement of a piston which discharges the fuel is arranged to drain the discharge pipe by suction so as to prevent after-drip. The piston 31 works in a cylinder 13 disposed in a well 25 in the base of a reservoir 34. Fuel passes from the reservoir into the cylinder to fill it through openings 32 in the cylinder wall when the piston returns to its normal position at the bottom of the cylinder. The piston rod 11 extends through the upper wall of the reservoir and there carries a disc 10 under which the end of a lever 6 pivoted at 40 engages. Upon pulling down a handle 7 after insertion of a coin the lever is rocked and lifts the piston to discharge the contents of the cylinder through a discharge pipe 14. The piston then returns under the weight of the disc 10 and, in so doing, applies suction to the discharge pipe to drain it. The stroke of the piston and the volume delivered can be varied by adjustment of the disc 10 on the piston rod. The pipe 14 discharges into a container 15 terminating in a discharge spout 16 outside the casing of the apparatus. Coin action, weight and mechanical connection. The handle 7 is connected with a vertical slide 8 straddling spaced coin-chute plates 1, a cross-pin 9 at the lower end of the slide working in slots 37 in the plates and being normally locked to prevent actuation of the apparatus by engagement with a notch 46 in a lever 4 pivoted at 4a and disposed between the plates. An inserted coin passes down the chute and comes to rest on a roller 5 on the end of the lever 6 and against the pin 9, pushing aside the notched lever 4 to release the slide 8. Downward movement of the slide when the handle 7 is actuated is then transmitted through the coin to the lever 6 to discharge the fuel. The coin is released to the till during the down-stroke of the slide 8 which is returned by a spring 38, a full stroke in either direction being ensured by a pawl 17 and rack 18. Coin-slit closing devices. A cranked rod 21, connected to a float 20 in the reservoir, releases a flap to cover the coin slot when the reservoir is empty.
