Title: Improvements relating to the Cleansing of Tanks
Inventor: MACDONALD THOMAS
IPC: B08B9/093
Filed: 1966-03-14
Abstract: 1,186,343. Cleaning tanks. NEWCASTLE BREWERIES Ltd. 14 June, 1967 [14 March, 1966], No. 11043/66. Heading A4F. [Also in Division B2] Apparatus for cleaning tanks comprises a water container 4, a pump 6 the discharge outlet 33 of which is connectable to a nozzle inserted through an opening in the top of the tank, a closure valve 12 in a pipe 8 connected to the bottom of the water container, a valve 13, and a valve 15 in a drainage pipe 10. The end 34 of the pump inlet manifold 7 is connected by flexible tubing to the bottom of the tank and a pipe 9 connects a detergent container 5 to the pump inlet manifold via a valve 14. The valves 12, 15 and a water inlet valve 16 are initially opened (the valve 13 being closed) when the electrical controller 17 is switched on. Water is supplied to the container 4 via a pipe 11 until the level reaches a probe P1 which completes a circuit through a probe P2 to cause closure of the valve 16 and to switch on the pump 6 to spray water into the tank via the nozzle. When the water level in the container 4 falls below the bottom of probe P3, the circuit through the probes P3 and P2 is broken, thus stopping the pump and re-opening the valve 16 to refill the container with water. When the water level reaches the bottom of the probe P3 for the second time, the pump is stopped and the valves 12, 15 are held open by a timer to enable the tank to drain through the valve 15 and the pipe 10. The timer then closes the valves 12, 15 and opens the valve 14 to allow detergent to be pumped into the tank until the level of the detergent in the container 5 reaches the bottom of a probe P4. The controller 17 then closes the valve 14, opens the valves 13 and a non-return valve 35 to circulate detergent through the tank for a period of time determined by the timer. The controller stops the pump at the end of this time period, opens the valve 15 and closes the valve 13 to discharge the detergent to waste. The valve 16 is then opened to refill the container 4 with water and a cycle of four rinses of the tank with clean water is initiated. The cleaning apparatus is mounted in a frame on wheels and modifications are described in which the pump is separate from the rest of the apparatus and the detergent container is omitted.

Title: Improvements relating to automatic valves for pneumatic brake systems
IPC: B60T15/18
Filed: 1930-04-08
Abstract: 350,638. Fluid-pressure brakes. ELECTRO-MECHANICAL BRAKE CO., Ltd. and SMITH, S., Eagle Works, West Bromwich. April 8, 1930, No. 11113. [Class 103 (i).] An automatic valve for a pneumatic brake system comprises a spring-controlled piston valve p, a cylindrical body part a having seatings with which the valve co-operates, passages d, f in one side of the body leading to the main reservoir and pressure pipe respectively and passages q, p, r in the other side of the valve leading to the brake cylinder, train pipe, and to an auxiliary or the main reservoir, respectively, and a supplementary air-operated and spring-controlled valve s controlling communication between the train pipe and the brake cylinder. The valve b is normally held against a seating u by a spring o. The main reservoir supplies air through a restricted opening i to the pressure pipe f and by leakage past the valve b to the auxiliary reservoir. The driver's valve is situated at the junction of the pressure pipe and the train pipe, and when opened allows air to flow from the pressure pipe and through the train pipe p to the pipe q to the brake cylinder. If the emergency valve in the pressure pipe is opened by the conductor or if the pressure pipe is broken the pressure of air in the auxiliary reservoir overcomes the spring o and forces the valve b to its opposite end position in which seatings g, h are engaged, thus shutting off communication between the main reservoir and pipe d, the pressure pipe f and the auxiliary reservoir pipe r. The auxiliary reservoir air moves the supplementary valve s supplying air to the brake cylinder and closing the train-pipe connection p. On closing the emergency valve pressure rises in the main reservoir side of the valve through a leak port n until the valve b returns to its original position closing the connection between the auxiliary reservoir and the brake cylinder. Release is effected by the driver's valve and through the pipes q, p. The seat k is movable in the valve b against spring pressure.

Title: Improvements in or relating to polyurethanes
Inventor: JONES JANET ELIZABETH
IPC: C08G18/38
Filed: 1963-03-21
Abstract: A process for the preparation of polyurethanes comprises reacting an organic polyisocyanate or polyisothiocyanate with a hydroxy reactant comprising a phosphnitrilic polyol ester component and a halogen-containing polyhydroxylic polyether, said hydroxy reactant providing from 0.5 to 3% by weight of phosphorus and from 5 to 30% by weight of halogen based on the weight of hydroxy reactant.  The halogen-containing polyether may be the reaction product of a halo-substituted alkylene oxide, e.g. epichlorhydrin with a nucleating agent, e.g. water, propylene glycol or glycerol.  An optional polyether not containing halogen may be also added and may be obtained from an alkylene oxide and a nucleating agent.  The phosphonitrilic polyol ester component may be prepared by reacting a polyhydric alcohol with a phosphonitrilic halide in quantities such that the corresponding phosphonitrilic polyol ester is formed. A mixture of halides having the general formula (PNCl2)n or (PNBr2)n may be used.  Clycols mentioned are: ethylene, diethylene, triethylene, propylene and di-, tri- and tetrapropylene glycols.  In an Example (5) a reaction mixture comprising the phosphonitrilic glycol ester of dipropylene glycol and compounds of formula (PNCl2)n, a glycerol epichlor hydrin adduct, tri ethylene diamine, triethylamine, silicane oil, diphenylmethane diisocyanate and citace water or trichlorofluoromethane were foamed in a "one-shot" process to produce a polyurethane foam.
