Title: New or improved process for the depilation, neutralization and bating of hides and skins
IPC: C14C1/00
Filed: 1920-10-12
Abstract: 156,079. R÷hm, O. Dec. 31, 1919, [Convention date]. Treatment preliminary to tanning.-Relates to processes for the depilation, neutralization and bating or hides and skins by means of pancreatic enzymes after a short preliminary treatment with an alkaline solution .and consists in adding a salt of an alkali or alkaline earth to the alkaline solution in order to obviate stiffness and overplumping. The alkaline solution may contain caustic alkalis, alkaline earths or ammonia, the salts of alkalis to be added thereto comprising sodium or potassium sulphate or chlorides of sodium, potassium, calcium, barium, &c. After the preliminary treatment, in order to neutralize the caustic alkali, sodium bi-carbonate or other suitable agent such as ammonium sulphate or chloride or weak acids such as boric or lactic acid, may be added together with the pancreatic enzymes. The preliminary treatment with, for example, caustic soda and sodium sulphate may be intensified to effect depilation before treatment with enzymes. The mixture of caustic soda and sodium sulphate may be used as a bath or by painting it on to the flesh side. Preferably the alkalis and alkali salts are mixed together in the solid state, being fused and reduced to the form of small tablets or fragments. The enzyme liquor remaining after depilation or bating may be used again for the preliminary soaking of hides, &c. The Specification as open to inspection under Sect. 91 (3) (a), comprises also a process in which hides are bated in a liquor comprising 100 litres of water; 100 grams of pancreas extract; 150 grams of ammonium sulphate; and 250 grams of sodium sulphate. This subject-matter does not appear in the Specification as accepted.

Filed: 1927-11-02
Abstract: 293,251. Hobson, Ltd., H. M., (Assignees of Bandemer, W. E.). Aug. 1, 1927, [Convention date]. Indicators actuated pressure of head of liquid.-In depth-indicating devices, e.g., for petrol tanks, in which a pressure gauge is connected to a bell immersed in the liquid, air is supplied to the bell to keep it full by means employing the surging of the liquid in the tank. A cup 13 is carried by the tube 5 connecting the bell 7 and gauge 2 and by the filling tube 11, and a tube 14 extends from the cup to the underside of the bell. When the liquid is surging due to the movement of the motor vehicle, the cup 13 becomes filled and then drains out through the open-ended tube 14 and the opening 15. The tube 14 empties before the cup 13, and further draining of liquid through the opening 15 draws air in through the top of the tube and' delivers it below the bottom of the bell. The air passes upward through an opening 10 and replenishes the air in the bell. A number of modifications are described, in all of which the liquid conduit 14 has a separate air inlet below the open upper end.

Title: A new sulphide composition for painting which resists the action of light and heat
IPC: C09C1/06
Filed: 1919-11-25
Abstract: 156,971. Nishizawa, Y. Nov. 25, 1919. Pigments.-Substantially neutral organic compounds containing two or more hydroxyl groups are mixed with metallic sulphides or substances containing metallic sulphides, for the purpose of obtaining a pigment or paint composition which will resist the action of light and heat. In examples, zinc sulphide is treated with the abovementioned class of compounds among which mav be included glycol, the saccharides, and salts and esters of tartaric and poly-hydroxy-stearic acids. Treated in this manner, zinc sulphide undergoes no perceptible change when exposed to ultra-violet rays for 5 to 6 hours, or is heated gradually to a temperature of 120‹ C. Several methods of mixing the two ingredients are given. The sulphide may be incorporated with the organic compound itself or with its aqueous solution. Zinc sulphide may be added to the latter. and after settling the clear liquor poured off and the deposit removed and dried. Or the sulphide may be precipitated for instance by means of ammonium sulphide, in the presence of the organic compound. Finally, the " preventer " may 'be formed in the presence of the metallic sulphide. For example, zinc acetate may be added to a suspension of zinc sulphide in tartaric acid, and the zinc sulphide soaked in the resulting zinc tartrate removed and dried.

Abstract: 536,235. Thermal switches; actuation of switches. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Nov. 6, 1939, No. 29472. [Class 38 (v)] A switch comprising a movable contact 4 carried by a bi-metallic strip 1, and a contact 7 carried by a fixed member 6, is provided with a spring 15 of " C " or like form dispersed between the fixed and movable members in such a way that when the switch is open it tends to hold the contacts apart with a force which rapidly diminishes as the contacts close, in order to produce a quick make and break action. The spring approaches, but does not pass through, a dead-centre position as the contacts move to the closed position. The spring 15 is held between a pair of pivot points 12 and a single pivot point 14 carried by brackets secured respectively to the members 1 and 6. The operating temperature is controlled by adjusting the fixed contact by rotation of a cam 9, which engages a pin 8 carried by the spring member 6, a depression in the cam providing an "off" position in which the switch remains open. The movement of the strip 1 is limited by adjustable stops 5 and 16, the latter being carried by a bracket mounted on the strip 6.

The circuit of the motor E is however completed through a shunt and the motor continues to rotate until an insulating member f<2> on the drum f comes opposite a contact as shown in the Figure, when the motor circuit is broken and the drum is clamped. A ticket-printing mechanism is operated by the motor E through a drum k, and a number of keys are provided, one of which is selected according to the desired route. Upon depressing the selected key, the secondary circuit of the particular discharge tube N illuminating the desired route is completed through an electromagnetically-operated switch u.
