Title: Improvements in or relating to the preservation of proteins and proteinaceous materials
IPC: A23L3/3463
Filed: 1948-11-22
Abstract: 663,098. Preserving proteins. SHERWINWILLIAMS CO. Nov. 22, 1948 [Dec. 22, 1947], No. 30308/48. Class 49 For retarding putrefaction, proteins or proteinaceous materials are dissolved in aqueous alkaline solution, to this solution is added a protein preservative soluble in alkaline, but insoluble in neutral or acid, solution, e.g. chlorobenzoic acid, bromobenzoic acid, salicylic acid, phenol, orthophenylphenol, 2,4, 5-trichlorophenol, 2, 3, 4, 6-tetrachlorophenol, pentachlorophenol, or 2 halo, 4- phenylphenol, and an aqueous acid solution is then added to precipitate at least some of the protein and preservative. An example is concerned with treating castor bean protein by solubilizing in sodium hydroxide solution of pH 11, adding sufficient tetrachlorophenol to result in an 11 per cent. concentration thereof in the protein subsequently precipitated, adding sufficient 5 per cent. sulphuric acid solution to attain pH 3À9, and filtering off the excess liquid, the resulting product consisting of 75 per cent of acidified water and 25 per cent. of protein and preservative. Specification 657,509, [Group IV(b)], and U.S.A. Specification 2,502,484 are referred to.
Patent GB-947024-A (GB)
Title: Improvements in or relating to arrangements for counting pulses
IPC: H03K23/78
Filed: 1962-08-08
Abstract: 947,024. Photo-electric counting circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 8, 1962 [Aug.11, 1961],No. 30392/62. Heading G1A. [Also in Division G4] The invention relates to a ring counter made up of two parallel sets of electroluminescent elements. In the first set of elements SO-S9 when an element is on E1 radiates energy while photoconductors P1, P2 have high and low resistances respectively. Irradiation of P1 turns the element off with E1 not radiating and P2 having high resistance. In the second set of elements S10-S19 four states are possible, (1) E2 not radiating and P4 with low resistance (2) E2 radiating and P4 with low resistance, this being the "on" condition, (3) E2 not radiating and P3, P4 having low resistance, and(4) E2 not radiating with P3, P4 having high resistance, this being the "off" condition. Operation. Assuming SO is on, application of radiant energy to photoconductor 2 turns on S10, E1 of SO having reduced the resistance of P4 in S10. E2 then maintains P4 at low resistance and irradiates P2, P3 of elements S1,S11. Element S1 then switches on and its electroluminescent element E1 irradiates P1 of SO which switches off. The process repeats round the ring for successive pulses of light applied to element 2. Modification. Instead of switching off SO by irradiation from E1 of S1 it may be effected by the coupling shown in dotted lines from E2 of S10. Reversible counter, Fig. 2. A pair of counters arranged back-to-back are subject to +ve and - ve counting pulses on the left and right of the Figure to step the counter in one or other direction.

Abstract: 1,169,473. Twisting. SUZUKI KOSAKUSHO K.K. 27 June, 1968 [12 Sept., 1967], No. 30645/68. Heading B3E. [Also in Division H2] Insulated wires are electrically interconnected by having their end portions twisted together, Fig. 6, while heat is applied to a part of the twisted region to soften or burn the wire insulation; continued twisting results in the wire cores in the heated region contacting one another, and eventually in the breaking off of the extreme end portions of the wires. When the wire insulation is of plastics material such as PVC or polyethylene, a layer of insulation remains around the twisted wire splice; when paper-insulated wires are joined, insulating material may subsequently be applied around the splice to replace the burnt-off paper. Fig. 1 shows apparatus for joining insulated wire end portions (not shown) which are extended in parallel from a retaining plate 6 where the wires are held fast against rotation, over the open side of a heating chamber 5, round a rotatable hook 12 and finally round a fixed U-shaped bitt 15. Operation of a trigger 2 (or of a lever 33) closes a microswitch 18 to energize an electric motor 14, which rotates hook 12 to twist the wire end portions together; simultaneously, a fuel gas is supplied, via an inlet pipe 22 in the handle 3 of the apparatus and a control valve 27, to a burner 4 in heating chamber 5, a pilot flame therein being fed via a regulating valve 30. In a modification, Figs. 7-9 (not shown), the gas burner is replaced by an electric resistance heater supplied in parallel with motor 14.

Abstract: 365,163. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. and MONTGOMERY, A. W., Columbia, House, Aldwych, London. Oct. 16, 1930, No. 30977. [Class 40 (v).] An amplifier for a two-way transmission system comprises two or more valves arranged in push-pull with respect to currents in one direction and in parallel with respect to currents in the opposite direction. Signalling currents from L1 having a carrier frequency f1 are applied in push-pull to the valves V1, V2 through the filter IF1 and transformer T1 and pass to line L2 through T2 and filter OF1. Currents from L2 of frequency f2 are rejected by OF1 and pass through IF2 and T3 to V1 and V2 which are in parallel for this input. The output passes through transformer T4 and filter OF2 to the line L1, IF1 preventing f2 currents from feeding into T1. The filters may be of the band-pass type, or high- and low-pass filters may be employed. Automatic or other gain control may be applied to either direction without affecting the other, as by potentiometers across primaries or secondaries of the input or output transformers ; the input voltage from either direction may be similarly adjusted.

Abstract: 152,895. Fairweather, W., (Singer Manufacturing Co.). Dec. 18, 1919. Sewing-machines; lock-stitching by hooks.-A ring hook 23 with an inwardly-tuurned beak 24 is rotated in an inclined plane by means of bevelgearing 15. A stationary thread-case supporting plate 22 is mounted in a race-way 21 in the hook ring and is formed with a rectangular aperture for the reception of a spool-case 30 carrying a commercial reel of thread with its axis substantially in the plane of the hook. The hook makes two revolutions for each stitch. The supporting-plate 22 is provided with wing portions 35 and the upper part of the thread case is extended at 43, Fig. 8, for the purpose of passing the needle-thread loop over the thread case. The thread case parts 40 rest upon the supporting plate and the case is held in place by a spring catch 41<x>, Fig. 2, on its end wall. Slots are cut in the thread case and form convenient apertures for the fingers of the operator in removing the thread case. The hook thread passes from the spool through a slot in the wall of the case and under the upper portion of a tensioning spring 47, Fig. 2, has two downwardly extending projections 51, Fig. 9, that pass into perforations in the thread-case. One projection is bevelled at 52 to facilitate the drawing of the thread under it and into the space between the two projections. The supporting-plate 22 is held from rotation by a projecting tongue fixed upon it which engages a notched plate 39 on the machine bed-plate. To prevent vibration of the plate, a leaf-spring is fitted to one side of the tongue and engages one side of the retaining notch. The under thread in passing to the stitching point passes over the feed-dog, and the latter in its rising movement serves to pull off thread from the under spool. The rim of the supporting plate is notched for the purpose of keeping the raceway clear of lint &c. Governing needle thread. The take-up arm 55, Fig. 2, is bifurcated and a fixed thread-guiding wire 60 passes between the bifurcations. The spring serves to retain some of the slack thread during the middle portion of the downward stroke of the take-up arm and to yield it up near the bottom of that stroke when the needle-thread loop is being passed round the thread case. The take-up arm is pivoted to an operating crank-pin 7 and to a link 58 pivoted at 59 to the machine frame.

Title: Improvements in and relating to the production of metal alkyls
Inventor: SMITH PETER
IPC: C07F5/06
Filed: 1953-11-18
Abstract: Aluminium trialkyls are prepared by decomposing a complex metal alkyl of aluminium and an alkali metal at elevated temperature and substantially in the absence of moisture and oxygen in the presence of a Friedel-Craft catalyst as defined. The catalyst should not cause undesired decomposition reactions. Suitable catalysts are aluminium halides, aluminium alkyl halides, zinc chloride and ferric chloride. The reaction may be carried out under reduced pressure so that the aluminium trialkyl distils off as it is formed.  An inert solvent e.g. decalin or other paraffinic or alicyclic hydrocarbon may be used as reaction medium.  If desired the decomposition may be carried out on the complex alkali-metal aluminium alkyl prepared according to Specification 757,524 without isolation from the reaction mixture. In an example lithium aluminium tetrapropyl is heated at 200 DEG  C. at reduced pressure in the presence of aluminium chloride, aluminium tripropyl distilling from the reaction vessel.  The Provisional Specification refers also to the application of the process to the production of tri-alkyls of boron, gallium, indium and thallium.
