Title: Improvements in or relating to apparatus for separating dust or the like from gases or vapours
IPC: B04C5/12
Filed: 1935-10-08
Abstract: 445,245. Centrifugal gas - cleaners. SKAJAA, T., Kristiansands, Norway. Oct. 8, 1935, Nos. 27741 and 27742. Convention dates, Oct. 8, 1934, and June 19, 1935. [Class 23] A separator in which dust or the like is separated from whirling gas or vapour is provided with means at the gas outlet or dust outlet or both to prevent suctional return flow of gas or vapour into the separator. The arrangement may be applied to a single separator vessel, or to a number of such vessels, each consisting of a cylindrical tube 4, combined in one apparatus as shown in the Figure. The gas outlet tubes 7 are arranged at one end to communicate with the main outlet 2, and the annular space between each separator 4 and its tube 7 contains vanes 5 to rotate the gases. The dust laden gas passes from the inlet A past the vanes 5 into the tubes 4 and the dust is thrown to the walls while the clean gas passes through outlet 7. A circular plate 8 on a rod 9 is mounted in proximity to the flared end of each outlet 7, the plate being adjustable in position so that the free discharge opening can be varied. The plate prevents any inward flow of clean gas. A similar adjustable plate 11 is placed at the opposite end of each tube 4. The diameter of the plate 11 is slightly less than that of the tube so that a small annular dust outlet is formed and the dust drops into the hopper 3. An outlet D at the top of the hopper permits the escape of the gas passing through the dust outlet. A slight suction may be applied at the outlet D to mamtain a pressure difference between the tubes 4 and the hopper 3. The plates 11 can be used to remove any dust particles from the walls of the separators and any plate 11 can be moved co the end of its associated tube 7 to cut out a particular separator. Each plate 8 may be slightly convex, or have bent edges, or may be fitted with a spiral whirl chamber to assist in the change of the gas velocity into pressure.

Abstract: 1,132,748. Semi-conductor devices. SIEMENS - SCHUCKERTWERKE A.G. 21 June, 1966 [22 June, 1965], No. 27763/66. Heading H1K. In a semi-conductor device a pressure contact in the current path is made to or through a porous sintered body of high heat conductivity. The body, preferably having a porosity of 2-40% may consist of silver, copper, silver mixed with copper, cadmium, nickel, graphite, molybdenum sulphide or tungsten selenide; or of copper mixed with graphite, molybdenum sulphide or tungsten selenide. If desired, the body may comprise two layers. One of the layers may consist of or contain a lubricant and the other not, or one layer may be of a cheaper metal than the layer used as the pressure contact face. Examples of both kinds are given. A typical rectifier, illustrated in Fig. 4, consists of a silicon body alloyed with aluminium to a molybdenum plate 14 at one face and alloyed with gold antimony at the other. The assembly is clamped to the copper base through sintered disc 17 by the conventional spring assembly shown. In this case the upper contact is a molybdenum plate 20 hard soldered to copper rod 18. Alternatively, a sintered pressure plate may be sintered to the face of the molybdenum plate or disposed between it and the gold antimony layer. In other arrangements the silicon body with alloyed faces is disposed between metal diaphragms through the intermediary of sintered discs, the diaphragms being connected at their peripheries by a ceramic ring to form a housing. In Fig. 6, the element is soldered between two molybdenum members 40, 41, one of which, 40 has a silver plate attached to its lower face, and mounted in a similar housing. In this case a sintered silver plate 49 is clamped between one face of the housing and a contact member 48 designed to provide cooling.

Title: Fuel injection pumps
IPC: F02D1/00
Filed: 1973-06-14
Abstract: 1435014 Fuel injection pumps: regulating I C engine fuel injection SIGMA DIESEL 14 June 1973 [19 June 1972] 28437/73 Headings F1A and F1B A fuel injection pump similar to that described in Specification 1428824 (Division F1) is modified in that the axis about which the rocker lever 23 pivots is moved by a single acting ram in response either to a fluid-pressure servo coupled to an operating parameter of the associated I.C. engine, or preferably, to the pressure of super charged air being delivered to the engine and thereby adjust the delivery of the pump. The arrangement is such that a reduction in pressure causes a reduction in delivery per revolution of the pump and conversely for a pressure increase. The single acting ram 50 comprises a piston 56 rigidly mounted on a rod 51 for reciprocation within a cylinder casing 61 integral with the pump's housing and closed by a plug 62. A flexible diaphragm 57 joins the piston to the casing 61. One end of the rod 51a is secured to return springs 64 and the other end is connected by a link 53, arms 49 and 47 interconnected by a pivot shaft 48 and a plate 44. The axis about which the lever 23 pivots is eccentric to a pivot shaft 38 to which the plate 44 is rigidly connected. In operation and as shown in Fig. 1 when fluid-pressure in a space between the diaphragm 57 and the plug 62 overcomes the springs 64, the piston 56 moves to the right thereby causing a clockwise rotation of the plate 44 and the pivot axis of the lever 23 to move towards the left. This movement causes the lower end 23b of the lever 23 to move to the left and thereby move the rotary valve 2 to the left and increase the pump's delivery. The piston 56 may act on the valve 2 before, at the same time or after the arrangement comprising the frusto-conical ferrule 17, balls 22 and end-face 2d of the valve 2 which act as described in the Specification 1428824. Reference has been directed by the Comptroller to Specification 947158.
