Title: Method and apparatus for the chemical treatment of water supplies
IPC: C02F1/68
Filed: 1972-02-19
Abstract: 1381673 Dosing apparatus J O'SHEA T SPILLANE and J SUGRUE 19 Feb 1972 7796/72 Heading B1C [Also in Divisions C1 and El]  The invention relates to water supply apparatus of the kind in which a pump 9 supplies water to a vessel 10 in which it is stored under air pressure and drawn off as required, the pump being periodically actuated by a level sensor in the vessel and a device 8 (see Fig. 2, not shown) being connected to the suction side of the pump to supply to it, on each actuation, a predetermined volume of air to replace air dissolved in the water in the vessel 10. As described the air intake pipe 1 of the device 8 passes through a container 2 for a liquid additive and has a bleed hole 6 through which the pipe 1 fills with additive during the time when the pipe is at cast. The additive may be a polymerised phosphate; a silicate or tannate; sodium carbonate or hydroxide; sodium aluminate or aluminium sulphate; sodium or calcium hypochlorite: sodium fluoride; or an antibiotic.

Title: Improvements in and relating to actuating devices for fluid control valves
IPC: F16K31/163
Filed: 1958-03-11
Abstract: 849,241. Fluid-pressure servomotor control systems. SOC. RATEAU. March 11, 1958 [March 12, 1957], No. 7847/58. Class 135. A device for actuating a valve controlled by a servomotor comprises two levers which are pivotally connected respectively to the output member of the servomotor and to the frame of the servomotor, the levers also being freely pivotally connected together and wherein one of the levers acts at one of its points on the valve closure member, while the other lever bears at one of its points on the valve body, the two points being so chosen that the forces exerted at these points on the valve closure member and the valve body during actuation of the valve are so arranged as to exert on the valve body a zero or relatively weak resultant force. Referring to Fig. 1 the lever l is connected to the rod t of the servo-piston p at s and bears against the stem of the valve closure member o at y. The lever c<SP>1</SP>, which is connected to a tubular extension c of the servomotor casing v at n, is pivotally connected to the valve housing at m<SP>1</SP> and is pivotally connected to the lever l at m. The points m<SP>1</SP> and y are arranged along the axis y-y<SP>1</SP> and the rod t and tubular extension c are coaxial. By taking moments about the point m it can be seen that the resultant force acting on the valve body during actuation of the valve is substantially zero. The servomotor frame v is articulated about a point G and ball joints may be provided at G, h, n or s to permit relative movement of the valve and servomotor casing caused by thermal expansion. The servomotor control valve v<SP>1</SP> may be actuated by a speed governor and the valve o may control the admission of steam to a turbine. In another embodiment the valve o may be cam operated and the cam shaft actuated by the lever system l, c<SP>1</SP> through a pinion. A number of valves may be actuated simultaneously by a series of lever arrangements similar to that shown in Fig. 1, wherein the lever systems are connected together by rods and counter rods.

IPC: F27B9/14
Filed: 1921-03-16
Abstract: 181,502. Steigner, W. G. de. March 16, 1921. Tunnel kilns; charging and discharging.-In a continuously-operated kiln for baking clay products having a substantially horizontal high-temperature heating-zone 13, and downwardly inclined end portions 11, 14 leading to the charging and discharging openings 12, 15 respectively, the goods are moved intermittently through the kiln, resting on fixed supports therein between the stepwise movements. The kiln is slightly wider than the articles to be treated, or the carriers therefor, and each side wall has two series of stepped ledges 19 leading upwards to a top horizontal ledge 20. In operation, the goods are moved step-by-step up the inclined portion 11, then horizontally along the heating-section 13, and finally downwards to the outlet 15 along the section 14. The device for moving the goods consists of a stepped transporter 21 movable horizontally between stops 51, 52 on a support 36 which can be raised and lowered by screwed pillars 37, 38 operated simultaneously from a reversible electric motor 48. From the position shown, the transporter is first raised through a vertical distance slightly greater than the height of a step, thereby lifting the articles on each of the left hand steps to a level slightly above that of the next step above, and at the same time raising the remainder of the articles just clear of their supporting ledges. The transporter is then moved horizontally from left to right by the hand-lever 53, and lowered to deposit each article one step in advance of its previous position. The kiln is heated by flues 16 around the upper portion.

Spaced parallel arms 39 of the clamping piece 30 are clamped by a U-shaped piece 40 to a threaded stem 41 on the plate 15. A nut 42 is provided to give downward pressure to clamp the strip 32 as the clamping piece 30 swings about its pivot 31 to give a rigid tree. In a modification, in place of the arms 39 the strip 32 is extended and attached to the top of the toe piece 19 and locking action is effected by a screwed rod, pivotally attached to the wedge 23 and extending through the pieces 28, 30, which also actuates the wedge 23. In a further modification, a resilient rod passing through the toe piece 19, wedge 23, plate 15 and counter piece 28 replaces the strip 32 and additional side plates rearward of the former pieces 20, 21 are provided.
