Title: Slider for sliding clasp fasteners
IPC: A44B19/28
Filed: 1955-06-01
Abstract: 769,826. Sliding clasp fasteners. LIGHTNING FASTENERS, Ltd. June 1, 1955 [June 12, 1954], No. 15708/55. Class 44. In a slider for a sliding clasp fastener having one plate integral with a wedge portion, the other plate pivotally mounted on the wedge portion about a transverse axis and a spring-loaded slidable latch embodied in the second plate, the latch is adapted in one position to co-operate with the wedge portion to maintain the slider in the closed-in position and adapted to be moved against the spring pressure to another position to permit opening out of the slider. As shown, a top plate 1 is formed integrally with a wedge portion 2 to which a bottom plate 4 is pivoted. A spring-loaded latch member 13 is located in a cavity 11 in the plate 4 and normally projects through an end wall 8 of a groove 7 at the opposite end of the plate and engages under an abutment 6 on the wedge 2 to maintain the slider plates in the closed position. The latch is retractable to release the slider plates by means of an instrument such as a pin inserted through an aperture 19 in the plate 4 to engage an aperture 20 in the latch. Alternatively the latch may be provided with a projection which extends through the aperture 19. The slider is provided with a spring-loaded locking cap 22. The invention is applicable to non-locking type sliders. In either type the latch mechanism may be associated with the upper plate instead of with the lower plate as shown.

Filed: 1959-05-12
Abstract: 881,458. Coating by vapour deposition. STAUFFER CHEMICAL CO. May 12, 1959 [Aug. 4, 1958], No. 16160/59. Class 82(2). [Also in Groups XXII and XL(a)] In a method of electron-bombardment heating of a body in a vacuum, e.g. for evaporating material in the vacuum deposition of thin films, gas or vapour is released in the vicinity of the body and a gas pressure gradient is set up between the body and the cathode. Conditions are so adjusted that the electronic space charge is effectively neutralised, an ionic plasma surrounded by a positive ion sheath being formed near the body which serves as the anode. In Fig. 8 material 87 in a crucible 88 is evaporated by the cathode structure 90, 92 to form a thin film or coating on an article 89. The rate at which the gas or vapour is evolved is controlled by controlling the rate at which material is melted in the crucible 88 and by controlling the amount of electrical power supplied to the electrical discharge. The vacuum pumping rate is controlled to produce a pressure in the vicinity of the material 87 which is at least ten times the pressure at the cathode. In Fig. 9 an auxiliary gas supply is provided, the gas being supplied, e.g. from the atmosphere, through a duct 104 which may have a nozzle at its end. The cathode 101 is surrounded by a focusing shield 103. The material is supplied through a shoot 96.

Abstract: 739,714. Letting-off warps in looms. KURTZ, O., and KURTZ, H., [trading as KURTZ EISENWERK, P.]. June 30, 1952 [June 30. 1951], No. 16360/52. Class 142(2). In a loom let-off motion an increase in tension of the warp displaces the back rest of the loom, which through a lever system relieves the warp beam brake. The warp from a beam 2 passes over the back rest 3 which is pivoted about an axis 15. An increase in tension of the warp rocks the back rest and thereby actuates a lever system 16, 17, 11 against the action of a spring 12 to bring a set screw 32 into contact with a bolt 27 and thus ease the pressure on the beam of a brake band 35. When the screw 32 is disengaged from the bolt a spring 31 applies the brake, holding the beam against rotation. In another embodiment two brake shoes are employed in place of a brake band, the lower shoe forming a bearing supporting the warp beam.

Title: Method of preparing a stable nutritive product
IPC: A61K31/16
Filed: 1946-05-31
Abstract: A stable nutritive product for intravenous administration is prepared by making a solution of a hydrolised protein in an aqueous bath, adding to the solution as protective ingredient one or more of the compounds sodium hydrosulphite, sodium sulphite, sodium bisulphite and sulphur dioxide together with a compound containing an amino group and a mercapto group which groups are separated by two or three carbon atoms in the molecule, packaging the resultant solution and sealing such packages, and preferably throughout all the foregoing steps maintaining an atmosphere of inert gas in contact with the solution.  Instead of packaging the liquid, it may be evaporated to dryness at low temperature in vacuo, or may be frozen and the water removed by evaporation under high vacuum, to produce a dry product. Specified amino-mercapto compounds are cysteine, its hydrochloride and homocysteine.  The solution of hydrolysed protein may be prepared by refluxing finely-ground fibrin or casein with dilute aqueous sulphuric acid while bubbling carbon dioxide through the solution, the sulphate ions then being partially removed by precipitation as barium sulphate and the solution being decolourised by treatment with carbon.  Alternatively, the hydrolysis may be enzymatic.  Other proteinaceous material such as lung tissue, heart, muscle, plasma protein, whole blood, lactalbumin, pancreas residue, soyabean, wheat germ residue and wheat gluten may also be employed.  The composition may also contain glucose, inorganic salts such as sodium chloride, and vitamins such as thiamine, nicotinamide, riboflavin, pyridoxine and calcium pantothenate.
