Title: Method of increasing the rate of heat transfer between hot surfaces and a liquid in contact therewith
IPC: B22D11/124
Filed: 1956-07-16
Abstract: 844,757. Continuous - casting machines. STEIGERWALD, K. H. July 16, 1956 [Feb. 29, 1956], No. 21890/56. Class 83 (1). [Also in Group XIII] A method of increasing the rate of heat-transfer between a heated surface and a liquid separated from the surface by a vapour-film formed during heat-exchange between the surface and the liquid, comprises applying an electric voltage between the liquid and heated surface, such as to produce an electrical discharge through the vapour-film. In a continuous casting process, a casting 80 to be cooled is in close contact with the wall of a mould 81. A ring of refractory insulating material 83 is press-fitted into mould 81, and carries a spray-nozzle from which water is ejected on to the surface of casting 80, the resulting steam being evacuated through openings 84 in the member 83. The voltage generator 86 is connected between the nozzle 82 and mould 81, or the casting 80. It is stated that a magnetic field may be provided in or near the electric discharge zone. The current used may be alternating or direct, and a highfrequency current may be employed. The heated surface may be flat or cylindrical, smooth or roughened, and may be plated. The preferred liquid is water, but other liquids may be used if they are electrically conductive or made conductive by admixtures. The Specification indicates also that the hot surface may be formed by the boundary of a solid, gas, vapour or liquid.

Abstract: 935,572. Delivering measured quantities of liquid. GASKELL & CHAMBERS Ltd. June 12, 1962 [June 19, 1961], No. 21997/61. Class 106 (5). The horizontally disposed measuring cylinder 10 of a beer dispenser of the free piston type has inlet/outlet valves 17 in each end wall and situated above the level of the cylinder axis to permit the expulsion of gases with each draught. The valves 17 are interconnected by a yoke 2 controlled by a single handle which rotates the valves about a common axis through 90 degrees. In one extreme position of the handle one valve connects the cylinder to exhaust channels 20, 21 and the other valve connects the cylinder to the supply channels 24, 25. In the other extreme position of the handle the role of the valves is reversed. The liquid supply may be pressurized and the handle may be interlocked with the piston 14 so as to be held fast until the piston has completed a full stroke. The cylinder has detachable end walls held together by an axial bolt 13 so that the dispenser may be readily dismantled for cleaning.
Patent GB-152485-A (GB)
Title: Improved automatic weighing machine adapted for continuous service
IPC: G01G13/00
Filed: 1919-09-06
Abstract: 152,485. Roederstein, A. Sept. 6, 1919. Automatic feed-weighers.-In an automaticfeed weigher the main-feed gate in closing opens the dribble-feed gate and on completion of the weighment a connection between the two gates is broken and the dribble-feed gate falls and cuts off the feed. In Fig. 3 the weigher is shown with the feed gates 39, 43 closed, and the weighpan 9 open for the discharge of the weighed material. The weigh-pan is in two parts hinged on pins 14, and after the discharge a counterweighted shoot 16 swings upwards and an arm 18 attached thereto strikes a lever 21 and throws over a toggle 19, 21 so as to lock the two halves of the receptacle in the closed position. During this closure, links 34, 35 pivoted to the two parts of the receptacle rotate an arm 38 pivoted on the receptacle support 13. The arm 38 engages a two-armed lever 41, 55 and thus through a pin connection 42 swings the main feed gate 39 into the open position, carrying with it a notched lever 48. The receptacle is depressed by the weight of entering material until the arm 41 escapes from the arm 38 when the main feed gate 39 falls into the closed position, and in doing so opens the dribble feed gate 43 by reason of the engagement of a notch 49 with a projection 50 on an arm 51 of the dribble-feed gate. When the dribble feed is completed, a pin 73 on the pan support 13 trips the lever 48, and the dribblefeed gate falls into the closed position. This movement raises a lever 54 and causes a lever 25 to throw the lever 21 into the position shown and open the weigh pan, the series of operations being automatically repeated. By turning a handle 31, the lever 25 may be prevented from striking the lever 21, thus avoiding discharge of the weigh-pan and arresting the operation of the machine. During the filling of the weigh-pan a pair of sectors. pivoted beneath the weights pan, is partly supported upon the frame, and thus reduces the effective pressure of the balance weights, but before completion of the charge the sectors are raised clear of the frame by the rise of the weights pan. A pivoted lever compensates for the suspended material at cut-off. By means of a hand-lever the sectors and the compensating-lever may be simultaneously placed out of normal operation for the purpose of testing the balance of the machine.
