Patent GB-757215-A (GB)
Title: Improvements in or relating to the preparation of shaped products from globular protein
Inventor: EAST EDWARD
IPC: A23J3/28
Filed: 1953-08-18
Abstract: Filaments and other shaped products are prepared from globular proteins by continuously feeding an alkaline substance into a continuous stream of an aqueous solution or suspension of a globular protein so as to form a stream of solution which will mature to a spinning solution in an hour or less, and continuously passing the stream of solution so formed to an extrusion device immersed in a coagulating bath, the solution being extruded within an hour of the addition of the alkaline substance.  The preferred proteins are oilseed proteins, particularly soya-bean and groundnut protein.  A stock solution of groundnut protein having a concentration of about 20-30 per cent or of soyabean protein of 10-15 per cent concentration may be used.  The alkaline substance may be a hydroxide of an alkali metal or of ammonium.  The maturing time preferably does not exceed half an hour and may not exceed 10 minutes.  The alkali is preferably introduced in the form of an aqueous solution not exceeding about 20 per cent concentration.  The stock solutions of protein may have a pH of 10.0-10.5 and, in the case of groundnut protein, the initial pH of the protein solution after the addition of the alkali may be about 11.5-13.5.  The spinning solution is preferably extruded whilst its viscosity at the spinning temperature is between one-third of its peak viscosity and its peak viscosity.  In an example a stock solution of pH 10-10.5 is prepared by first preparing an aqueous slurry of groundnut protein and then adding, with thorough mixing, the requisite proportion of aqueous sodium hydroxide solution, air being excluded from the mixer and the solution being maintained under reduced pressure in order to de-aerate it.  A metered stream of aqueous 5.4 per cent sodium hydroxide solution is fed at a rate of 5.4 grams per minute into a metering pump together with a stream of stock solution.  The mixture is passed through a mixing device and then to a spinneret through a pipe and valve system which allows the length of the path of the spinning solution to be adjusted.  The spinning solution contains 20.6 per cent of protein and is fed to the spinneret at a rate of 75 grams per minute.  The initial pH of the spinning solution is 12.9, its spinning temperature is 20 DEG  C. and its peak viscosity at that temperature is 140 poises.  It is spun to form filaments at its peak viscosity, which is reached in 6.5 minutes after the addition of the alkali, into a coagulating bath containing 12 per cent of sodium chloride and 6 per cent of acetic acid.

Title: Improvements in or relating to means for eliminating leakage across the contacts of electrical switching devices
Inventor: GILLETT WILLIAM FRANCIS HERBER
IPC: H01H50/54
Filed: 1947-08-18
Abstract: 643,785. Eliminating switch contact leakage. STANDARD TELEPHONES & CABLES, Ltd. Aug. 18, 1947, No. 22882. [Class 38(v)] [Also in Group XL(c)] In order to eliminate leakage across the open contacts of spring contact sets, additional circuit elements are connected across the contacts to form a balanced bridge. A pair of contacts 5, 6 controlling an alternating-current circuit, have, when open, stray impedances represented by a resistance and capacitance in parallel, inductance being neglected, and the residual current permitted to flow between the ends 1, 2 and 3, 4 of the circuit, by this stray impedance, is eliminated by providing resistance-capacity balancing networks 7, 8 and 9, 10 to form a balanced bridge. To enable the bridge to be balanced at all frequencies and also to take account of inductance, the balancing networks may instead be constituted by additional unoperated spring contact sets 11, 12 and 13, 14 similar to, and mounted above, the switch contacts 6, 6<SP>1</SP>, 5, 5<SP>1</SP> and held in the open position. The system is limited by the shunting effect of the balancing networks when the contacts 5, 6 are closed.

A pulse width discriminating circuit for responding only to pulses of a predetermined minimum duration comprises a gate to one input of which the incoming pulses are applied via a delay circuit and to the other of which they are applied via an integrating circuit so that the gate produces an output only when the output of the integrating circuit has an amplitude exceeding a predetermined level. The Figure shows a pulse width discriminating circuit in which the input pulses at terminal 4 are applied via cathode-follower stage 5 and delay network 7 to the control grid of gating valve 1 and also via integrating circuit. 9, 10 to the suppressor grid of valve 1. The gate is normally closed but when due to a pulse of long duration being applied at the input the voltage at the integrating circuit 9, 10 exceeds a predetermined amplitude, Fig. 2 (not shown), the gate opens and a portion of this longer duration pulse after being delayed by network 7 is passed to the output terminal 18. The delay time of network 7 is less than the duration of the wider pulses it is required to pass and preferably greater than that of the narrower pulses in the input train. Rectifier 20 is poled to expedite the discharge of capacitor 10 in the absence of any input at terminal 4. Reference has been directed by the Comptroller to Specification 582,330.
