Abstract: 1,036,724. Valves. NATIONAL DEVELOPMENT CORPORATION. March 29, 1963 [April 6, 1962], No. 13334/62. Heading F2V. A fluid control valve, e.g. for use with a fermentation vessel, has a housing 1 threaded to the vessel 2, which housing has a chamber 3 with a lower opening directly into the vessel, and two upper openings 4, 5; the latter leads to atmosphere via a vent passage 6. A manually - operable threaded-shaft 8 connects with a collar 10 in the chamber 3, the collar carrying an 0-ring 11, which collar is slidable in a fluidtight manner in the opening 5. A spider 13 depends from the collar into the vessel, and is attached to an annular plate 16 inside the vessel, the plate coacting with an 0-ring 18 around lower end of the chamber 3. The plate is guided by rods 17 and supports a funnelended tube 14 which depends into the vessel, the tube 14 being open to the hole through the plate 16. The collar 10 enters the opening 5 before the plate 16 seats on the ring 18. With the parts as shown and a woollen plug in the passage 6 the valve is completely sterilized by air and steam expelled during sterilization of a culture medium in the vessel. Two such valves may be used, one functioning as an inlet valve supplying air to aerate the culture medium after inoculum has been supplied through the opening 4. If both valves are closed, the incoming air flowing through the opening 4 of one valve causes the culture medium to rise in the tube 14 of the other valve and flow out of the associated opening 4 to a sampling container. With the outlets 5 of both valves closed and the plates 16 unseated a current of air is passed over the surface of the culture medium to remove foam. In a modification, the vent passage is dispensed with and the valve solely comprises the lower annular-plate and tube with its associated seat member; the spider is attached to a flexible rubber, copper or brass diaphragm or bellows which is moved axially by a member threaded to a rotatably operating curb. Two such valves are mounted on a flanged plate which is connected by bolts and wing nuts to a flange on the vessel. With a valve secured to the bottom of a vessel and the tube extending upwardly the whole serves as a constant level and drain device.

IPC: B23K3/06
Filed: 1951-06-09
Abstract: 712,109. Soldering: making radiators. BRITTOLL RADIATORS, Ltd., and BYERS, E. V. Sept. 8, 1952 [June 9, 1951], No. 13724/51. Classes 83 (2) and 83 (4) A method of soldering the contiguous surfaces of assembled parts of an article consists in maintaining a positive circulation of molten solder in a vessel or dipping bath by means of a pump in order to cause the solder continuously to overflow opposite top edges of the vessel to form a top layer of overflowing solder and moving the article across the top of the vessel so that the lower part only of the article is moved through the said overflowing layer in the plane thereof. Molten solder overflows the longitudinal edges 7 of a bath 2, into an outer container 1, is pumped therefrom by a pump 5 into a well 10 where its head is adjusted by vertical adjustment of a plate 13 and then passes into the bath 2 through perforated pipes 11, the overflow being maintained at a desired height above the edges by adjustment of the pumping rate. A radiator cooling element comprises gills 18, Fig. 5, pierced by flat tubes 19 with longitudinal lapped seams 20, collars 21 being bent up to lie along the tubes. The radiator is traversed across the bath, Fig. 6, solder reaching those joint surfaces not dipping into the solder by capillary attraction. The traversing of the work may be effected by a motor driven screw device. In a modification, apertures are provided in the end walls 6 below the level of the overflow edges. If a long article is fed intermittently over the apparatus so as to allow successive sections to be subjected to manufacturing &c. processes, while stationary, the pump may be stopped when the article comes to rest and the level of solder in the bath 2 will fall below the overflow edges and out of contact with the article.

Title: Improvements in or relating to the automatic starting of internal combustion engines
IPC: F01L13/00
Filed: 1935-05-10
Abstract: 438,258. Starting; stopping. SULZER FRERES SOC. ANON., Winterthur, Switzerland. May 10, 1935, No. 13792. Convention date, July 20, 1934. [Class 7 (v)] For starting an engine which drives a generator for supplying additional current to electric power mains on the failure, overload or other abnormal condition of a main source of supply, a device for the supply of starting air to the auxiliary engine is operated in accordance with a value which is dependent upon the current flowing in the electric mains, and is automatically actuated to cut off the air supply when the engine has reached a predetermined speed. As shown, the engine 1 drives a generator 2 for the supply of current to mains 3 normally supplied by a main generator (not shown). A valve 18 for the supply of starting air from a bottle 19, through a pipe 24 and distributer 41 to non-return valves 23 on the engine cylinders, is normally closed by a spring 21. A piston 20 on the stem of the valve 18 is actuated, to open the valve, by the pressure of lubricating oil, which is supplied by a pump 9 through a pipe 14 to the cylinder 25 and thence through a non-return valve 42 and pipe 22 to a lubricating pump 31 driven by the engine. The pump 9 is driven by an electric motor 10, the circuit 11 of which comprises an electromagnetic switch 7 normally held open by current from the mains 3. A bell-crank lever 28 controlled by the switch is connected to an arm 37 on a valve 27, which normally connects the cylinder 25 through a discharge pipe 26 to the oil reservoir 13. On the failure of current in the mains, the automatic closure of the switch 7 energizes the motor 10 and the valve 27 is closed by the lever 28 and arm 37, so that the pump 9 supplies lubricant through the cylinder 25 to the pump 31, and the starting valve 18 is opened by the pressure of the lubricant acting on the piston 20. When the engine starts and reaches a predetermined speed, an engine-driven governor 6, acting through a lever 36, returns the arm 37 and switch lever 28 to the normal position shown, breaking the circuit 11 and opening the byepass valve 27, so that the starting-air valve is closed by the spring 21. The mains are then supplied by the engine-driven generator 2 until the failure, overload, &c. of the mains supply is overcome, when the engine 1 can be stopped by moving a member 43 controlling the fuel pump 4 of the engine. In a modification, the governor 6 is omitted and the switch 7 is opened and closed solely by the variation of current in the mains supply.
