Convention date, Oct. 25, 1929. [Class 38 (ii).] In order to obtain smooth transformation over a large band of frequencies a highfrequency transformer has connected in series with at least one of its windings a resistance equal to the surge impedance of the winding. An amplifying valve. Fig. 1, is connected in series with a transformer primary L1 and a resistance R. This resistance is equal to the surge impedance of the winding L1 considered as a transmission line having inductance and capacity C to earth. The winding L1 connected with the resistance R has the characteristics of an infinitely long transmission line. In a modification the capacity to earth is obtained by means of an earthed screen arranged either inside or outside the winding. Circulating currents are prevented by longidudinal slots. In a further modification shown in Fig. 3 the secondary winding is also arranged to have transmission line characteristics. Capacities C are connected between parts of the winding and a conductor 2 and resistances R between the ends of the winding and the conductor. These resistances are each equal to the surge impedance of the winding. The action is treated mathematically in the Specification.

Abstract: 602,691. Refrigerating. HOOVER, Ltd. Nov. 9, 1945, No. 29947. Convention date, Nov. 13, 1944. [Class 29] Absorption systems.-An inert gas system has two evaporators E, E<1> supplied with inert gas of different refrigerant vapour content from separate absorbers A, A<1> traversed in series by the absorbing solution, the absorber A<1> delivering the leaner gas being cooled by the evaporator E receiving the richer gas. The boiler B is in open communication with an analyser D and has a second analysing chamber 15 separated from the boiler by a partition 11 and heated by the hot vapour from the analyser D to liberate substantially pure refrigerant vapour from rich solution supplied to the chamber 15 by a pipe 18. This vapour passes to a condenser C by a pipe 19 with a rectifier R, and the condensate is supplied by a pipe 21 to the low temperature evaporator E', which is embedded in the insulation 29 of a chamber 31 for frosted foods within the cabinet, and evaporates into very lean inert gas supplied by a pipe 26 from the absorber A<1> which is surrounded by the high temperature evaporator E for cooling the ice trays 52 and the cabinet space. The partially weakened solution in the chamber 15 passes to the analyser D and boiler B and the vapour from the analyser D passes by a pipe 38 with a rectifier R<1> to a second condenser C<1> supplying the evaporator E, where it evaporates into inert gas which has passed through the low temperature evaporator E<1> and through pipe 24, gas heat exchanger 27 and pipe 44 to the lower end of the evaporator E. From the upper end of the evaporator E the inert gas passes by a pipe 47 to a gas heat exchanger G, air cooled absorber A, fan F, gas heat exchanger G, pipe 58 and absorber A<1> and thence by the pipe 26 and gas heat exchanger 27 to the evaporator E<1>. Weak solution from the boiler B is conducted to a reservoir S and through a gas lift conduit 64 and gas separating chamber 65 to the absorber A<1>, pumping gas being supplied from the fan F by a pipe 66. From the bottom of the absorber A<1> the solution passes by pipe 71, liquid heat exchanger 72 and pipe 73 to the top of the absorber A and thence by pipe 78 and liquid heat exchanger L to the analysing chamber 15. A thermostatic switch 95 controls the fan F and a solenoid-operated valve 91 supplying gas to the burner. In a modification two independent inert gas streams are circulated by gravity, the fan F being omitted and the high temperature evaporator comprising a pipe coil in heat exchange with a coil forming the absorber A<1>. The lean inert gas circulates between the absorber A<1> and the evaporator E<1>, while the richer inert gas circulates in a separate circuit between the evaporator E and the air-cooled absorber A.

Title: Improvements in or relating to a baking form
IPC: A21D8/08
Filed: 1951-12-21
Abstract: A composition for coating the surfaces of a baking form to enhance the release of goods baked in contact therewith, comprises a mixture of a fusible, organic solvent-soluble, polymeric allyl ester of a polybasic organic acid and a curable resin, which is a polysiloxane, a phenol-aldehyde condensate, a urea-aldehyde condensate or a phenol-urea-aldehyde condensate or any mixture thereof, the allyl polymer and curable resin being incompatible in the cured state.  The composition is usually applied as a 20 to 45 per cent solution in, for example, xylene, toluene, benzene, acetone, dioxane, chloroform, acetates or a mixture thereof. Effective compositions contain 1/10 to 4 per cent of the curable resin based on the weight of the allyl polymer.  The allyl polymers specified are those derived from glycol diallyl-, diethylene glycol, and ethylene glycol dimethallyl-carbonates, diallyl phthalate, diallyl maleate and triethylene bis-(allyl carbonate).  Curable resins specified are methyl-, ethyl-, methylphenyl-, ethylphenyl-, methylcresyl-, phenyl-and cresyl-silicones, alkaline catalysed phenolformaldehyde (B-stage) resin, which may be made soluble by boiling with a low boiling aliphatic alcohol.  In examples, the compositions consist of (1) diallylphthalate polymer, xylene, polyalkylsiloxane resin and isopropyl alcohol, and (2) diallyl glycol carbonate polymer, toluene, phenol-aldehyde (B-stage) resin, isopropyl alcohol, butyl carbitol and ethanol.ALSO:The release of baked goods, e.g. breads, cakes, and rolls, from a metallic baking form is enhanced by coating the form with a composition comprising a polymeric allyl ester of an organic polybasic acid and a curable resin, viz. a phenol-aldehyde, urea-aldehyde, phenol-urea-aldehyde or polysiloxane resin, or any mixture thereof (see Group IV (a)), the allyl polymer and curable resin being incompatible in the cured state.  The surface(s) of the baking form (pans, trays, implements and moulds) is preferably coated with a solution of the composition, e.g. by dipping, brushing or spraying, the solvent allowed to evaporate and the coating cured. The incompatibility of the cured resins causes crazing which imparts a minute cellular outer texture to the crust of the baked goods.
