Abstract: 724,798. Stoppers. SCHLICKSUPP, T. F. Feb. 13, 1953, No. 4137/53. Class 125 (3). A self-closing closure for a collapsible tube 1 has a fixed member 6 supported at its inner end on a plate 7 having openings 8 and a movable tubular member 4 with discharge outlet 11 and movable between the wall 3 of the tube and the member 6.

Title: Improvements in the manufacture of gramophone needles
IPC: G11B3/48
Filed: 1942-03-31
Abstract: 556,432. Regenerated cellulose articles treating textiles &c. with liquids &c. COURTAULDS, Ltd., GIVENS, J. H., and PROCTOR, J. March 31, 1942, No. 4263. [Classes 2 (ii) and 15 (ii)] Gramophone needles are made of regenerated cellulose monofils, hardened with artificial resins. In an example, a regenerated cellulose monofil is swollen by steeping in water, and is then immersed in a solution of a formaldehydeurea condensation product for about 12 hours to ensure thorough impregnation. The impregnating solution may be obtained by mixing formaldehyde solution, urea, and ammonia solution, heating the mixture to 90‹C. for several minutes, diluting with cold water, and adjusting the hydrogen ion concentration to pH 4 by the addition of acetic acid. After the impregnation, the monofil is removed from the solution, dried at 40‹C., and stoved at 140‹C. to complete the hardening process. It is then cut into suitable lengths and one end of each is sharpened to a fine point.

In an ultra-violet lamp having a quartz or fused silica envelope, the part of the envelope 5 surrounding a lead-in conductor 4 has an insert 7 of material capable of reducing the transmission of radiation along this part. The total internal reflection of radiation within the part 5, owing to its high refractive index, tends to cause overheating of the vacuum-tight seal to the knife-edged molybdenum cup 6, which is reduced by the inserted collar 7 of material more opaque to ultraviolet radiation. The material 7 may consist of a translucent silica containing a multiplicity of air bubbles.

[Class 83 (ii).] A screw-stopper for bottles &c. formed of metal and comprising a top portion and a skirt, the skirt having an undefaced outer surface, and a plurality of internal thread engaging lugs formed from tongues of metal integral with the inner wall of the cap skirt, said lugs being located at progressively increasing distances from the edge of the cap skirt, is characterized by the fact that said tongues from which said lugs are formed are of substantially equal lengths. Fig. 7 shows the product of an operation in which strips 19 of unequal length are cut out of a continuous horizontal portion of the skirt 16 and then bent downward through 90‹, tongues of equal length are then shaved from said strips and rolled up to form beads 17, and the remnants of the strips are cut off at their junction with the main skirt portion 16. Another method consists in cutting the skirt so as to leave a helical edge, shaving tongues of equal length from the inside of the skirt, rolling them up to form beads 22, Fig. 10, and finally severing the lower portion of the skirt along the line X-X. Or, as shown in Fig. 12, tongues of equal length may be shaved from the helical edge of the thick portion 26 of a long-skirted cup.

Patent GB-752669-A (GB)
Title: Improvements in or relating to the preparation of insulin
IPC: C07K14/625
Filed: 1954-02-15
Abstract: Insulin is recovered from an aqueous solution containing siliceous impurities by adjusting the pH of the solution to between 6,5 and 9,0, preferably 7,5 and 8,5 e.g. with 6N sulphuric acid, and precipitating the impurities as a flocculant precipitate.  Pancreas glands are extracted with a 50 to 85 per cent aqueous solution of an organic solvent e.g. ethanol, methanol, acetone, at a pH below 4 e.g. using hydrochloric, sulphuric or phosphoric acid, and the extract is treated with a siliceous adsorbent e.g. clay, Fuller's earth, kaolin, kieselguhr, diatomaceous earth, bentonite, montmorillonite and "Super Filtrol" (Registered Trade Mark) which may be in the form of a packed body, at a pH of 2 to 4, to adsorb the insulin.  The insulin is subsequently eluted by contacting the adsorbent with an aqueous eluent at a pH of from 9, to 13, preferably from 10 to 11,5 e.g. using ammonium hydroxide, trisodium phosphate buffer, alkali or alkaline-earth metal hydroxide.  The siliceous impurities are precipitated from the eluate, and the separated supernatent liquid further processed to recover the insulin e.g. by adjusting the pH to approximately 2 and salting out with sodium chloride.  The adsorbent may be washed with a non-insulin-eluting solvent e.g. methyl ethylketone, 95 per cent 3A alcohol, prior to the elution.

Title: Sighting device for carriage mounted weapons for firing at moving targets, particularly aircraft
IPC: F41G5/14
Filed: 1949-04-12
Abstract: 638,828. Gun sighting apparatus. STEVENS, A. H. (Zbrojovka Brno, Narodni Podnik). April 12, 1949, No. 4806/47. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 19, 1947.] [Class 92 (ii)] The angle of lead α for the elevational and azimuthal parts of a device for sighting against moving targets is derived from the formula where t is the time of flight, L the present range, D the future range, and # the angular velocity of the target, and is obtained by rotating a disc at a speed proportional to t/D.L combining this speed with a co-operating female threaded friction wheel whose shaft rotates at a speed proportional to # and whose carrier is connected to the sighting element. Space diagram.-Fig. 2 shows the target at C, the sighting station being at O, and the targets future position at Z. The method of obtaining from the diagram the formula quoted above is given in the Specification. Apparatus.-The apparatus shown is mounted on the gun barrel and includes couplings 1, 2 which respectively receive rotations corresponding to the elevational and azimuthal movements of the gun. The coupling 1 serves to rotate a threaded (#) shaft 13, thus to move a friction wheel 14 across a disc 16, the wheel being connected to a sighting mark O. The coupling 2 likewise drives the shaft 7 of a wheel 8 across a friction disc 10, the wheel being connected via racks 9, 38 to a sighting mark N. This mark receives a further adjustment by a solid cam 43 which is translated by an elevation device 44, 45, and rotated by a range (L) knob 25. The two t discs are rotated at a speed proportional to -.L D by a wheel 18, which is displaced in proportion to that quantity over a disc 17 driven at constant speed and which drives a disc 26 geared to the said discs. The positioning of the wheel 18 is effected by the range knob 25 and a target velocity knob 23. The knob 25 translates the wheel 18 by means of circular rack- and-pinion mechanism 21, 22, and the knob 23 positions a cam 20, these two adjustments being combined by gear 30 and a follower 33, rack 34 and gear 35, respectively in a differential 36 to rotate a dial 32. When the range on the dial 32 gives, against a fixed mark 37, the correct range L, the wheel 18 is correctly displaced.
