Patent GB-446967-A (GB)
Title: Improvements in and relating to the production of casein
IPC: A23J1/14
Filed: 1934-10-08
Abstract: Casein is extracted from vegetable material such as soya bean by treatment with soda lye, calcium hydroxide, ammonia, organic bases or water and the solution is treated in the anode compartment of a diaphragm cell for precipitation of the casein. The anode may be of graphite, preferably electro-graphite, and the diaphragm of asbestos. A current density less than 1 amp. per sq. dm. is employed.  The initial catholyte preferably contains soda lye, calcium hydroxide, ammonia or other substance employed in the extraction.  The anode chamber is preferably relatively tall and of narrow cross-section. The precipitated albumen forms a foamy mixture with the liberated oxygen; this rises to the surface and is there freed from a considerable proportion of its liquid content by further electrolytic action.  The resulting cathode liquid may be employed for further extraction.  The anode liquid after precipitation of the albumen may be treated for isolation of carbohydrates by evaporation or crystallization or may be fermented into alcohol or other products. Amines formed in the anode chamber may be added to the cathode liquid for use in further extraction.  When the extract is made with water only, a small amount of alkaline substance in solid, liquid, or gaseous form such as alkali or alkaline earth metal or magnesium hydroxide or carbonate, ammonia or an amine is added before or during electrolysis.  The process may be conducted in a continuous and cyclic manner.

Title: Improvements in control valve for automatic water softening apparatus
IPC: C02F1/42
Filed: 1922-10-24
Abstract: 212,954. Marks, E. C. R., (Wayne Tank & Pump Co.). Oct. 24, 1922. Actuating by liquid pressure; free piston pumps.-A device particularly adapted for controlling the flow of water from a watersoftening apparatus such as is described in Specification 206,684 comprises a plurality of parts which when in engagement constitute a loosely-fitting piston adapted to be moved by pressure to expel a volume of liquid which has previously leaked to the other side and then cut off the flow, the said piston parts then automatically disengaging and severally returning to their initial re - engaged position. The moving piston works in a cylindrical tube 7 held between inlet and outlet chambers 2, 1 by bolts 33 and comprises a lower perforated part 6 recessed on its upper surface to receive a corresponding rib on the upper part 5 which is provided with a valve face 8. As the valve approaches its seat 17 it raises a perforated pusher 10 loaded by a spring 20 and weight 15. The outlet 16 from the chamber 13 is smaller than the passage through the pusher so that the liquid expelled by the piston acts on a diaphragm 14 to raise the weight and allow the valve to seat. The part 6 is now detached and returns to its initial position. As the chamber 13 empties the weight descends and acting through the spring 20 and pusher 10 unseats the valve which then falls through the liquid to re-engagement with the lower part and the cycle is repeated. The outlet from the chamber 13 is controlled bv a manually-actuated cock 32 or by a mechanicallyactuated valve so as to insure a constant flow.

Filed: 1973-06-20
Abstract: 1384853 Mould provided with a ventilation valve F HODLER 20 June 1973 [5 Oct 1972] 29373/73 Heading B3F [Also in Division F2] A mould having a ventilation duct 4, 18, 14 is provided with a valve for closing the duct, the valve comprising a piston 5 urged into its open position by a displacement member when the mould is open, and means 8 actuated by closure of the mould to move the displacement member away from the piston 5 so that the piston can be brought to its closed position without being hindered by the displacement member load, the arrangement being such that the piston moves to its closed position in the direction of the pressure exerted on it by the casting material. The piston 5 is urged towards its open position by a spring 10 which bears against a displacement member 9 which in turn bears against a plate 12 attached to the piston. When the mould is closed rods 8, which pass through the plate 12, are moved to the right and push the member 9 away from the plate 12 against the action of the spring 10. The piston 5 remains in its open position until a pressure medium is admitted to the space 23 to move the plate 12 and thus piston 5 to the right until the plate 12 again bears against the member 9. In this position the piston head 6 is located within the bore 17 and blocks the connection between the parts 4 and 14 of the ventilation duct. The shape of the piston head 6 is such that the pressure of the casting material causes the periphery of the head to be pressed against the wall of the bore 17. Two valves may be provided, one in each half of the mould.
