Filed: 1958-02-18
Abstract: 840,537. Bending glass sheets. PITTSBURGH PLATE GLASS CO. Feb. 18, 1958 [March 1, 1957], No. 5219/58. Addition to 770,131. Drawings to Specification. Class 56. In a sectionalised glass bending mould wherein intermediate parts of flat glass sheets are supported by the ends of the side rails of the centre section of a sectionalised mould (the ends of the sheets being supported by the outboard ends of the wing sections), the amount of metal in the ends of the side rails is reduced to prevent too great a heat gradient in the sheets at those points. This may be effected by undercutting the ends of the rails to reduce their height at the ends and/or by drilling apertures through the rails adjacent their ends only.

Abstract: 957,408. Packaging; opening liquid filled packages. WATNEY COMBE REID & CO. Ltd. May 16, 1960 [Feb. 16, 1959], No. 5323/59. Headings B8C and B8D. A tube of flexible taint-free synthetic plastic material is filled with an aerated or carbonated beverage whilst the surface level Z therein is acted on by a counterpressure, the filled tube being passed to means 5 where it is divided into liquid-tight receptacles. The tube may be formed by an extrusion head 4a and be surrounded by a sleeve 4d where it is turgid, rollers 4g being used to draw the filled tube through the sleeve. The beverage level in a supply tank 1 is kept approximately constant by a float-controlled inlet valve 1a the beverage being subjected to a back pressure P of carbon dioxide via a pipe 1g 1e being a pressure relief valve. A pressure controller 2, comprising a suspended bell in a vessel containing a predetermined quantity of water is used to maintain a pressure differential between the gas in the tank 1 and the gas in the plastic tube of an order maintaining the liquid level in the tube at the height Z. A second and similar pressure controller 3 maintains a slightly reduced pressure externally of the tube, in the moulding apparatus 4, as compared with the gas pressure inside the tube. A cooler 3c chills the gas supplied by the pressure controller 3. Should the plastic tube burst a check valve 4f prevents loss of liquid from the tank 1 and check valves 2c and 3d prevent loss of gas. The filled tube may be divided into individual containers by twisting one filled portion relatively to another and the twisted portions sealed by welding or by a clasp. Alternatively, the filled tube may be divided into units by transverse seals. In a modified construction the tube is formed from a flat strip of synthetic material that is sterilized by means such as an ultra-violet lamp and in this construction the pressure controller 3 is not used. Emptying the containers.-Where the containers remain joined together they may be advanced by means engaging the neck portions between them so as to draw the containers over a knife, the released beverage being collected by a funnel or shoot for transfer to a tumbler or like vessel. If the containers are separated from each other they may be forced individually into a funnel, having a knife or spike therein, to release the beverage into the funnel and thence into a tumbler or like vessel.

Abstract: 848,357. Copying by scanning. ILFORD Ltd. Jan. 30, 1959 [Feb. 19, 1958], No. 5465/58. Drawings to Specification. Class 40(3). In an arrangement for copying a coloured original employing a known focus of contrastmasking system in which light from a flying spot cathode-ray tube is directed through the original on to colour film on which the copy is to be made and thence to a photo-electric cell the signals produced by which are fed to a control electrode of the cathode-ray tube so as to reduce the beam intensity, the spectrum of the light produced by the tube is arranged to have energy peaks of predetermined relative intensities in the bands (e.g. red, green and blue) to which the copy colour film is responsive and the photo-electric cell is arranged to respond to only part of such spectrum. By arranging that such part is in the green portion of the spectrum loss of brightness in saturated blues and reds is reduced when subtractive colour film is employed for the copy image. The tube may be arranged to produce the necessary spectral range of the light by employing suitable phosphorus for the tube screen or by the use of colour selective filters or by the use of both and colour filters may be employed in conjunction with the photo-electric cell to produce the desired response.

Abstract: 470,282. Recoil - loading firearms. SANDERS SMALL ARMS, Ltd., and SANDERS, T. F. Feb. 26, 1936, No. 5812. [Classes 92 (ii) and 119] Relates to firearms automatically reloaded by the recoil of the gun relatively to an inertia, member or a fixed support and in which slotted rotary discs are used to effect the locking of the breech bolt. According to the invention, the breech bolt 3, Fig. 7, is locked by a single rotary disc-like member 6 pivoted above the breech on a substantially central vertical axis on the breech casing 1 and having a lug 7 projecting forwards to engage a rearward facing shoulder 8 on the bolt and a spring 11, Fig. 4, for urging the disc to the locking position. The recoil of the barrel and bolt relatively to an inertia weight 10 when the gun is fired causes a pin 12 and shoulder 13 on the weight to rotate the locking member to the unlocking position where a slot 9 in the member comes opposite the shoulder 8 of the bolt and allows the bolt to move away from the barrel to open the breech. In a modification, a crank on the locking member is operated by a pin on a fixed support relatively to which the barrel and bolt recoil.

Title: Improvements in or relating to the manufacture of viscous protein solutions for the production of artificial filaments and filaments derived therefrom
IPC: D01F4/00
Filed: 1943-04-12
Abstract: The process described in Specification 537,740 for preparing viscous aqueous caustic alkaline solutions of peanut globulins suitable for spinning textile filaments is varied for the purpose of producing solutions which can be stored for longer periods of time such as a week or longer without losing their spinnable capacity.  The variation consists in using caustic alkali having a concentration not less than 0.8 per cent calculated as NaOH, but lower, for example, by 0.4 per cent, than the optimum caustic alkali concentration as determined according to the prior Specification, maintaining the freshly prepared solution at an elevated temperature, for example 35 DEG  C. to 60 DEG  C., until it has attained its maximum viscosity, and then cooling to atmospheric temperature.  The concentration of globulin necessary to produce the best result is slightly higher than that according to the prior process, so that the actual caustic alkali concentration to be employed, which depends upon the globulin concentration, will normally be less divergent from that according to the prior process using a lower globulin concentration.
