Filed: 1972-05-09
Abstract: 1389343 Sampling liquids J R JOYCE 9 May 1973 [9 May 1972] 21470/72 Heading B8N A device for lowering into a body of water to take samples at various heights from the bottom comprises a frame in which are clamped inverted bottles f having apertured bases closed by flap valves a and tubes i leading from their necks to grommets p at various heights from the frame base, the tubes passing through a common shut off valve l. The valve is formed by three rollers between which the tubes pass, the upper central roller being connected to a weight o which, when the device is suspended for lowering into the water, projects beneath the frame base, the weight then causing the tubes to be squeezed and closed. When the device touches bottom, the weight is raised and water flows into the tubes to the bottles, the flap valves, previously held closed by water pressure, rising to release air. When the device is recovered, the weight shuts off the tubes, the flap valves close and the samples are trapped in the bottles. One tube outlet may be level with the frame base to sample the water at the water-bottom interface.

Patent GB-1474606-A (GB)
Title: Motor-drive controlling apparatus for a photographic camera
IPC: G03B17/42
Filed: 1974-05-15
Abstract: 1474606 Motor drives for cameras OLYMPUS OPTICAL CO Ltd 15 May 1974 [18 May 1973 30 May 1973 4 Oct 1973] 21537/74 Heading G2A A motor for driving shutter release and film winding mechanisms, and a timing circuit which is reset every time the shutter release is effected, are such that when the timing circuit continues to operate for longer than is required to effect the shutter release and then the film wind, its output serves to de-energize the motor. One form of the motor control circuit is shown in Fig. 1, in the condition when an operating switch 27 or 28 is opened, and the film winding operation is completed. The contacts of a change-over switch 2, a shutter switch 3, a relay switch 6 and a further relay switch 8 are as shown, the motor 1 is shortcircuited and stopped. When a switch 5 in circuit with a DC supply 4 is closed, capacitor 22 in the timing circuit 12 begins to be charged. When switch 27 or 28 is now closed, motor 1 rotates to drive the shutter releasing mechanism, after which it stops. For single-frame photography the mode change-over switch 14 is set so that terminals j, k are connected, and the shutter release and film wind operated as described above. If the film wind is disabled, owing to film termination, or faulty operation of the winding mechanism, the shutter releasing mechanism is not energized, and the timing circuit 12 is not reset. The charge building up on capacitor 22 is utilized to stop the motor 1, so that it does not continue to rotate unnecessarily. For continuous photography switch 14 is set so that terminals j, l are connected. If the film wind in this case is also disabled owing to film termination or faulty operation of the winding mechanism, the timing circuit is again not reset, and the motor is again stopped. A number of modifications of the Fig. 1 circuit are described for producing the same control of the motor.

Patent GB-479901-A (GB)
Title: A new or improved method of producing laminated structures from wood veneers
IPC: B32B21/13
Filed: 1936-08-06
Abstract: Plywood is made by coating veneers with a liquid or syrup phenol-formaldehyde primary condensation product of which the pH value is adjusted so that it is capable of drying at atmospheric temperatures to a solid fusible form, and which is then capable of hardening to the insoluble form at temperatures below 100 DEG  C.; drying the coated veneers at a temperature not substantially greater than 50 DEG  C.; and then uniting them under a pressure below 150 pounds per square inch and at a temperature of 90 to 105 DEG  C. The resin may be prepared by heating equal weights of phenol and 40 per cent formaldehyde in the presence of an alkaline catylist sufficient to give the mixture a pH value of 7--9, the mixture being refluxed for one hour at a temperature of 105--110 DEG  C., and 30 per cent of water being subsequently removed under reduced pressure.  Before application to the veneers the pH value of the syrup is adjusted by the addition of an organic acid, such as oxalic acid, or a mixture of organic acids; a pH value of 0,5--1,5 is stated to give the best results.  The addition of the acid results in a rise in viscosity, and the liquid is therefore thinned before application to the veneers, either temporarily by adding a volatile solvent such as acetone which evaporates before substantial penetration into the wood occurs or, if penetration is desired, by the addition of a higher boiling solvent such as a glycol ether.  The syrup is applied to the veneers in a spreading machine, or otherwise, and dried at a temperature of 20--30 DEG  C. for 6 to 12 hours, or more rapidly at a temperature of 40--50 DEG  C. for 1 to 2 hours.  The assembled veneers are then pressed at 60 pounds per square inch between polished plates heated to 80--100 DEG  C.  Plasticizers, fillers, dyestuffs and pigments may be used to produce boards of varying flexibility and colour.

Title: Improvements in or relating to recovery of cycloserine
IPC: C07D261/04
Filed: 1955-07-27
Abstract: Cycloserine is recovered from an impure aqueous solution by precipitating it as an insoluble metal salt, removing the precipitated salt, slurrying it with water, precipitating the metal ion of the insoluble salt of cycloserine as a water-insoluble salt and recovering cycloserine from the aqueous solution thereof.  The impure aqueous solution of cycloserine is adjusted to pH 5.5 to 9.0 prior to or after the addition of a water-soluble salt of the metal capable of forming a water-insoluble salt with cycloserine. Specified metals are silver, copper, mercury, zinc, lead, aluminium and cobalt, which may be used in the form of silver nitrate, cupric chloride, copper sulphate, mercuric acetate, zinc nitrate, zinc sulphate, lead acetate, lead nitrate, aluminium chloride, cobalt nitrate, cobalt chloride and cobalt sulphate.  The metal salt of cycloserine is slurried in water and the metal ion removed by (a) precipitation with hydrochloric acid and/or hydrogen sulphide in the case of silver; (b) hydrogen sulphide in the case of copper and mercury; or (c) any material capable of precipitating the metal ion as an insoluble salt.  Cycloserine is recovered from the resulting aqueous solution by (a) freeze drying or (b) addition of a water-miscible solvent such as acetone, methanol or dioxane. The initial impure cycloserine solution may be a filtered broth or the eluate obtained after adsorption of a filtered broth on a strong basic anion exchange resin in the hydroxyl form and elution with an anion other than hydroxyl, e.g. water-soluble sulphates, chlorides, acetates, formates, citrates and oxalates; sulphuric acid, hydrochloric acid, acetic acid, formic acid, phosphoric acid, citric acid and oxalic acid.  Suitable resins are Dowex-1 and Dowex-2, "Amberlite" XE75 (Registered Trade Mark) and Amberlite IRA-410. Specification 768,007 is referred to.

Abstract: 743,366. Cartridges for igniting fuels. OLIN MATHIESON CHEMICAL CORPORATION. Aug. 6, 1953 [Aug. 20, 1952], No. 21728/53. Class 9(1) An igniter cartridge 20 for igniting the fuel in the combustion chamber 42 of a jet engine has a casing 22 of paper, cardboard or metal, with a brass base 34 housing a primer 24 as in a shot-cartridge. At the forward end of the casing is an ignition charge 26 adapted to be ignited by flash from the primer 24 through a flash tube 30, which is surrounded by the main gas-producing charge 28. The main charge extends from base wads 35 to the ignition charge over which is a, closure wad 36 on to which the casing is crimped. The flash tube, which has a press-fit in the base 34, has an enlarged end to receive the primer 24. Fuel is injected into the combustion chamber 42 through a nozzle 44 where it mixes with compressed air entering through the inlet 46 to form a combustible mixture. On actuation, by remote control, of a trigger 52, a percussion pin 50 fires the cartridge 20 in a mounting 48-on the engine and a, stream of hot gases and molten metal is projected into the chamber 42 to ignite the fuel-air mixture. The main charge 28 may be made up of a slow-burning base charge 56 and a faster burning intermediate charge 58 which is a blend of the base charge and the ignition charge compositions. The base charge may be about 25 per cent by weight of powdered magnesium, 60 per cent by weight of a pulverulent oxidizing agent such as alkaline earth peroxide or nitrate with small quantities of fuels such as oxalates and binders such as metal soaps, e.g., calcium resinate. The ignition mixture may consist of 15 per cent by weight of powdered magnesium and about 85 per cent by weight of an alkaline earth peroxide with small amounts of insoluble metal soap. The intermediate charge is preferably a blend of 80 per cent of the base charge composition and 20 per cent of the ignition mixture, while the ignition charge is 80 per cent by weight of the igniter mixture and 20 per cent of the base charge. The flash tube 30 is made of a combustible metal such as aluminium, magnesium, zinc or alloys thereof. Before firing, the forward end of the tube is closed by pressing equal portions 64 of the wall inwardly to form radial fins 66, Fig. 9. On firing, flash from the primer forces the fins apart. These fins may be sealed by dipping in lacquer.
