Title: Improvements in high speed fluid control valves
IPC: F16K17/10
Filed: 1962-04-05
Abstract: 990,038. Fluid control valves. BRAKESHOE INTERNATIONAL S.A. April 5, 1962 [April 13, 1961], No. 13125/62. Heading F2V. [Also in Division G3] A fast response valve is formed by bodies 20 of various sizes, shapes and conduit fittings but all having the same size vertical cylindrical base 21 leading to a lower inlet 22-equivalent to that necessary for the valve carrying the greatest flow-containing a liner 33 ported at 36 for connection to an outlet 23 via a bore recess 32 and a spring-loaded piston valve 37 seating at its lower end on a sleeve shoulder 35, the top of the body being flat and containing the bore opening and two passages 25, 57 loading to the inlet and outlet respectively and receiving one of several kinds of central valve body. As shown inlet pressure acts via restriction 31 in passage 25 on a plunger 62 having a restriction 70 loading via orifice 55 to the rear chamber 45 of the piston valve whereby the spring and the equal pressure on both sides of inlet 37 hold it closed. Inlet pressure above a certain value moves plunger 62 to the right to open cone valve 74, adjustably loaded at 65, from its seat 63 and relieves pressure in chamber 45 whereby valve 37 opens as a relief valve. The plunger 62 may have side ports which are closed as it moves into its guide 61, passage 57 being blocked and an outlet formed to the right of valve 64. The plunger may be solid and respond to a central pressure-other than inlet-with the inlet connected to passage 25 being blocked, so that the valve acts as an unloader. In this case inlet pressure reaches valve chamber 45 via a restriction in plug 41. For low pressure valves, the plunger 62 is dispensed with.

Abstract: 451,715. Submarine mines. BENINI, Z., 2, Via della Fonderia, Florence, Italy. May 7, 1935, No. 13496. [Class 9 (ii)] A submarine mine adapted to be automatically moored at a given depth comprises three main parts, an anchor 20, a float 8, and a mine proper 1, the mine and the float being connected together by a cable 4 passing round pulleys 5, 6 on the anchor and wound on a drum 7 in the float, the arrangement being such that all the parts first go to the bottom, then the float rises and pays the cable out until the drum is locked by an hydrostatic device 9 when the float reaches the desired depth, a leak 16 being at the same time opened to allow water into the chamber 17 of the float, and after this the mine rises to the desired depth while the float sinks to the bottom. Meanwhile, a soluble plug 18 is dissolved away and the flooding of the float is completed by water leaking through a hole 19 into the side chambers of the float. The cable is attached eccentrically to the mine to cause the mine to rise in an inclined attitude to avoid collision with the falling float.

Title: Travelling railway ballast treating machine
IPC: E01B27/10
Filed: 1978-04-07
Abstract: The ballast-bed-cleaning machine has a bogie frame (1) supported on running gears. To receive the ballast beneath the track, use is made of an endless clearing chain (6) which is guided, in the form of a polygon obliquely with respect to the track plane and via deflecting rollers (10), in a chain-guide transverse path (7), which can pass through transversely beneath the track skeleton (3, 4), and two chain-guide longitudinal paths (8, 9) which are articulated on said transverse path and on the bogie frame (1). The two chain-guide longitudinal paths (8, 9) can be swivelled, via drives (31), upwards and to the side. Moreover, the two longitudinal paths (8, 9) are designed such that they can be vertically displaced in a telescopic manner by parts (20, 21) which are displaceable relative to each other, as a result of which the shape of the articulation polygon formed by the clearing chain (6) can be altered, while maintaining the peripheral length of the clearing chain (6), corresponding to the required setting angle of the chain-guide transverse path (7) with respect to the track axis (17). <IMAGE>

Filed: 1944-07-19
Abstract: 583,380. Washing milk cans. McFERRAN, J. S. July 19, 1944, No. 13850. [Class 138 (i)] In a machine for washing milk or cream cans, the cans are fed down a slide 8 fitted with holes 8A for introducing jets of steam and drainage holes 8B, and the cans are passed to one of ten compartments 3 in a vessel 2 which is rotated in a casing 1 by Geneva stop mechanism so that each compartment 3 advances by an amount equivalent to a tenth of a rotation of a shaft 4 which is driven from a worm 45 in an oil casing and drives a worm-wheel 47 connected by a shear pin to the driving-member 49 of the Geneva mechanism which drives a starwheel 55 on the shaft 4 by means of a crankpin 51, Fig. 6, not shown. The compartments 3 register in turn with the slide 8, and also with nozzles for applying jets of water, detergent, hot water and hot air to the tops and bottoms of the cans and to the lids. After receiving jets 13A, 14A of cold water, the cans are arrested so as to drain before passing to jets 17A, 18A of a detergent supplied by a pump 16. After another interval, jets 19A, 20A of hot water under pressure are delivered by a pump 21 and then other jets 22, 23A of water almost boiling. Sterilizing is then effected by jets 24, 25 and finally drying is effected by hot or cold air from a blower 34. The cans are delivered to a shoot 28 provided with means for delivering jets 28A of hot or cold air, and a separate shoot may deliver the cleaned lids. Baffles 30, 31, 32 are provided to prevent loss of solutions. The pumps are driven by a belt 35 from the motor shaft 33 which also drives the worm 45. The second compartment is normally closed by a sliding door 38 which is fitted with cam projections for controlling the valves governing the supply of fluid to the jet nozzles and also a switch for controlling the driving motor, so that if the door 38 is opened by the operator or by accident the machine is stopped. Hinged doors 38A allow of access for maintenance purposes to the compartments other than the feed and discharge compartments.

Title: Improvements relating to the electrolytic production of aluminium
IPC: C25C3/06
Filed: 1922-05-17
Abstract: 180,326. Blasi, M. May 18, 1921, [Convention date]. Aluminium, obtaining.- In obtaining aluminium by electrolysis of fused alumina, barium oxide or metallic barium is added to the bath and the mixture is heated temporarily to approximately 1200‹ C. before electrolysis. Cryolite and fluorite may be added as fluxes. The heating may be produced by adding 10 per cent of powdered or fine grained aluminium to the barium oxide, the total addition in this case being about one-sixth of the weight of alumina. A little fluorspar may also be added. In subsequent operations, alumina is added and after fusion, aluminium mixed with a little alumina is also added, no further addition of barium oxide being necessary. Fluxing material is added to replace that volatilized. With a furnace containing 30 kilos of alumina using 20,000 amps. at a pressure of 7 volts, at least two operations per hour may be effected, each yielding 15 kilos of aluminium.
