As the water level falls the member 31 and float 7 fall until a trigger 33a engages a step 21a on the lever 21 and holds the valve open. The arm 8 continues to descend the link sliding through a hole in the arm, until the roller re-engages the notch and releases the trigger to allow the valve to close.
Patent GB-484659-A (GB)
Title: Improvements in treatment of latex
IPC: C08C1/08
Filed: 1936-11-04
Abstract: A purified rubber is obtained from latex by subjecting the latex to treatment to solubilize the nitrogenous material naturally present therein, removing the resulting aqueous solution, e.g. by centrifuging or creaming to leave a concentrated latex, diluting the concentrated with water, coagulating the diluted latex and finally washing and drying the resulting coagulum.  The solubilization of the nitrogenous material may be effected by treating with an alkali such as sodium hydroxide, potassium hydroxide, ammonium hydroxide or the carbonates or phosphates of the alkali metals, with or without an emulsifier such as soap and with or without heat and pressure; when the digestion with alkali is complete, the latex may be partially neutralized and a stabilizer, e.g. a sulphonic ester of a higher alcohol, may be added.  Alternatively, the solubilization may be effected by treating with enzymes such as papain and trypsin.  The treated latex may be diluted prior to concentration particularly if it is to be concentrated by creaming, and the concentration, particularly if it is effected by centrifuging, may be effected a number of times diluting with water between each operation.  Creaming agents specified are konyaku meal, gum tragacanth and Iceland moss with or without an emulsifier, e.g. potassium coconut oil soap; when heat decomposable creaming agents are employed, the cream may be heated before coagulation to decompose any residual creaming agent. After concentrating by creaming or centrifuging the latex is preferably diluted to a dry rubber content of not more than 5 per cent.  The coagulating agent may be formic acid.  Compounding materials, e.g. fillers, antioxidants, and coagulation accelerators such as b -naphthol which accelerates the coagulation of latex by acetic acid, may be added before coagulation.

Title: Method of indicating the presence of submarine objects, and apparatus therefor
IPC: B63B22/24
Filed: 1925-11-30
Abstract: 268,004. Bonniksen, C. W., and Barratt, S. Nov. 30, 1925. Phosphoretted-hydrogen signals.-A signal or smoke screen is produced by the combustion of phosphine stored under pressure, for example, in the liquid state and released under conditions created to ensure spontaneous combustion. The compound is prepared say by the action of water on calcium phosphide, the gas after being dried and then cooled, to condense out any P2H4, being received in a storage cylinder immersed in a liquid air bath or the gas may be liquefied by compression. To ensure the spontaneous ignition of the gas in contact with the air, an activating agent such as NO, P2H4, PSF3 or finely divided phosphorus is admixed either as a gas or as a solvent in the liquid phosphine. In the application of the invention to a submarine as shown in Fig. 2, the phosphine cylinder 20 and a cylinder 24 of say nitric oxide are mounted on the exterior of the vessel and communicate with valves 28, 25 controlled from within the vessel and admitting to a common rising pipe. To prevent too high a proportion of the activating gas, this may pass to a mixing chamber through a length of capillary tubing. According to the first Provisional Specification the phosphine may be generated in the usual manner on the submarine and hydrogen may be mixed with the gas to diminish solubility in the water. Specifications 1256/76, [Class 55, Gas manufacture] ; and 15191/09 are referred to.
