Title: Improvements in or relating to safety valves
IPC: G01F23/02
Filed: 1949-09-08
Abstract: 663,333. Safety valves. DEWRANCE & CO., Ltd. (Manning, Maxwell & Moore). Sept. 8, 1949, No. 23263/49. Class 135. To prevent leakage and the pitting and distortion of the contact surfaces in a safety valve having a movable valve member biassed into contact with its seat member, the contact surface on at least one of the members is provided on one side of a thin flange element formed on or affixed to the member, the other side of the element being exposed to fluid pressure, whilst the contact surfaces are made of like or unlike materials having a low coefficient of expansion and freedom from welding together. A spring-loaded, boiler safety valve 3, Fig 1, operable at high pressures, e.g. 1,500 p.s.i. and having a movable valve member 7 screw-threadedly mounted in a surrounding skirt 8 and co-operating with a seat member 4, is formed with a thin annular flange 18, Fig. 2, the tip 19 of which contacts the seat member. The skirt 8 is slidably guided in a member 9 secured between the valve casing 2 and its bonnet 12 whilst the seat 4 is surrounded by a removable blow-down ring 6. When the valve is closed, steam pressure acting on the upper surface of the flange 18 assists closure and, due to its flexibility and thinness, tends to increase the contact area between the valve and its seat and rapidly dissipates any heat to prevent local cooling and distortion and hence leakage. In a modification, the seat member 4, Fig. 5, is also provided with a thin annular flange 25. In another arrangement, the undersurface of the valve member flange is made plane instead of conical and cooperates with a plane seat surface. The contact surfaces are of like or unlike materials selected from 13 per cent chromium steel, nitriding steels, cupronickel alloys and the Registered Trade Mark materials Invar and Stellite. A deposit of chromium on the seat member may also be used.

Abstract: 781,851. Electric selectors. TELEPHONE MANUFACTURING CO., Ltd. Aug. 24, 1954 [Aug. 24, 1953], No. 23285/53. Class 40 (4). A selector of the type described in Specification 728,891, in which one of a number of finger magnets moves its associated finger to act as an interponent between a member operated by a main magnet and a card operating a related set of contacts, has guide surfaces to limit the movement of the interponent. Two sets of finger magnets 11, 14 lie on opposite sides of a guide block 31. Each finger magnet has an armature 44, Figs. 4, 5, pivoted on a knife-edge 44a and supported by a spring 45, the end 45c of which engages under the guide block. The upper end 45d is bent over and carries an interponent 46 or 50 which is normally clear of a bar 30. However, when a finger magnet is energized its associated interponent is brought into position over the bar 30 so that subsequent operation of the main magnet 20 lifts the bar 30, the interponent and the associated card 40 to close the corresponding set of contacts. A set of off-normal contacts has no interponent and is operated by the bar 30 every time. Movement of an interponent is limited by girders formed in the top of block 31 and by the lower edge of card 40. The embodiment described is also described in Specification 781,852 but the claims differ.

Abstract: 1420953 Hydraulic braking systems; valves AUTOMOTIVE PRODUCTS Ltd 15 May 1973 [19 May 1972] 23714/72 Headings F2F and F2V A valve for use in a vehicle hydraulic braking system having front disc brakes and rear drum brakes is located in the line between a pressure source and the disc brakes to prevent actuation of the disc brakes below the pressure at which the force of pull-off springs in the drum brakes is overcome, so that the two types of brakes are actuated simultaneously. As shown, fluid passes from an inlet 42 to an annular cavity 33 formed between a plunger 27 and the valve body 18 and then to a further cavity located between the end of the plunger 27 and the end wall of the valve body, an annular sealing ring 39 preventing flow to a bore 21. When the pressure in the further cavity is sufficient the force exerted by a spring 31 on plunger 27 is overcome and the plunger moves rightwardly allowing fluid to pass via bore 21 to the disc brakes. On brake release a valve member 44 is caused to unseat from a shoulder 45 against the bias of spring 46 thereby allowing fluid to pass back to the pressure source via a radial passage 36 and the inlet 42. In a further embodiment two outlets are provided and means are provided for facilitating bleeding of the system by holding the plunger retracted; this latter comprises a circumferential groove (71), Fig. 3 (not shown), in the plunger which is aligned with a radial hole (72) in the valve body a pin 13, Fig. 4, (not shown), being inserted therein to hold the annular sealing ring clear of the end wall of the valve body.

Title: Process for sulphating the non-ferrous metals contained in ores or metallurgical products
IPC: C22B1/02
Filed: 1933-08-28
Abstract: Non-ferrous metals such as zinc, cadmium, copper and lead contained in ores and metallurgical products such as pyrites and burnt pyrites are sulphatized by heating the materials under oxidizing conditions to the sulphating temperature in a rotary drum furnace and thereupon adding substances containing or furnishing sulphur trioxide, for example, powerful oxidizing liquids such as sulphuric acid, or solutions of readily decomposable sulphates such as ferric sulphate, or nitrate solutions, or decomposable solid substances such as ferric sulphate, or mixtures thereof.  The originating material may be in the form of oxides or sulphides or both.  Oxidic material may be heated to the sulphating temperature outside the furnace, preferably by direct heating in a rotary drum or multistage furnace.  Only the sulphide of iron should be converted to oxide. When the preliminary heating is effected in the rotary drum furnace, the heating gases may flow in countercurrent to the solid material, while the gases and material in the sulphating zone pass in concurrent relationship. Reference is also made to a countercurrent operation.  In examples relating to treatment of Meggen pyrites, 60 DEG  B<\>ae sulphuric acid is introduced through nozzles into the furnace when the sulphur content of the ore is from 3 to 10 per cent.  The temperature is 700 DEG  C.  The temperature may be varied by the addition of air or other gases.
