Abstract: 1,218,353. Pressure operated switches. MECTRON (FRIGISTOR) Ltd. 7 March, 1968 [13 March, 1967], No. 11774/67. Addition to 1,098,270. Heading H1N. [Also in Division G3] A sequentially operated microswitch assembly, particularly for a temperature reference apparatus (see Division G3) comprises separate microswitches A-C arranged in a slot in a platform 17 with the switches A, B, having operating levers 32, 33 formed to differing lengths and the switch C having a plunger 31. Expansion of a bellows (21), Fig. 1 (not shown), due to internal volumetric or pressure changes, moves an anvil (23) downwardly to operate the switches in turn, switch B controlling current to a thermoelectric unit, and switches A, C controlling an alarm such as a lamp at the extreme positions of the bellows. Platform 17 may be loaded by a spring 18 to compensate for excessive movement of bellows (21) hence relieving the assembly of excessive stress, or damage in such condition.

Title: Improvements in or relating to hydraulic pressure control valves
IPC: B60T13/18
Filed: 1950-05-12
Abstract: 668,029. Fluid-actuated valves. INTERNATIONAL HARVESTER CO. May 12, 1950 [May 26, 1949], No. 11920/50. Class 135 [Also in Group XXXIV] A control valve for hydraulic devices, e.g. brakes, comprises a plunger 59, slidable in a sleeve 29 provided in a body 27, to control the connection of a port 45 to either a pressure inlet port 44 or an exhaust port 46, the port 45 leading to a brake 14. The plunger is moved to connect ports 44 and 45 by a lever 85 through a sleeve 79, a spring 77, a. member 78 and a piston 73. The pressure applied to the port 45 moves the piston 73 against the spring 77, to a point where the pressure of the fluid equalises the spring pressure, and also acts on a wall 66 in the plunger. The wall is provided with an orifice 69 through which fluid leaks, permitting a spring 68 to move the plunger gradually to follow the piston 73 and close the inlet port 44. Increased pressure at the port 45 is obtained by moving the lever 85 to increase the force of the spring 77. On release of the lever, the plunger moves to connect the ports 45, 46 thereby relieving the pressure at the port 45 and releasing the brakes.

Abstract: 486,250. Indicating liquid - levels. MOHR, A. April 27, 1937, No. 12029. Convention date, April 27, 1936. [Class 123 (i)] [Also in Group XIX] In a liquid-level indicator of the type in which air is forced into an open ended pipe dipping into the liquid and its pressure indicated, oscillations of the pressure indicator due to impulses in the supply of the air under pressure, are avoided by the use of a regulable constriction in the conduit leading to the pressure indicator. A pump 2 supplies air to a dip-pipe t by way of a closed vessel 3 as described in Specification 481,060, the pressure being indicated by the height of liquid in the limb 4 of a U-tube manometer. Communication between the vessel 3 and the U-tube is controlled by a ball valve 8 pressed to its seating by a spring 9 the compression of which is regulated by a screw 10. The valve is raised only slightly from its seating by a screw 11, to damp the oscillations of the liquid. By manipulation of valves 14 and 18, the liquid in the vessel 3 and the gauge may be discharged when desired, and replaced by fresh liquid from the tank T. Specification 324,365, [Class 123 (i)], also is referred to.

Title: Improvements in and relating to pigments containing titanium dioxide
Inventor: MILLER ROY
IPC: B03D1/001
Filed: 1961-04-05
Abstract: Centrifugal hydroclassification of titanium dioxide containing pigments is facilitated by forming an aqueous slurry to which an alkaline reacting agent is added to give a pH greater than 8 and then adding an acid reacting agent to give a pH of 6.6-7.6.  The slurry so formed is used for hydroclassification.  The alkaline reagents may be, aminomethylpropanol, monoisopropanolamine, sodium hydroxide, sodium phosphates, or sodium silicates.  Acid reacting agents are mineral acids, or their salts, aluminium sulphate,titanium sulphate or zirconium sulphate. Concentration of titanium dioxide in the slurry to be classified is preferably within 300-600 gm./litre. Specifications 456,420 and 944,216 are referred to.ALSO:In the hydroclassification of titanium dioxide containing pigments a modified Bird centrifuge is used.  The conventional Bird centrifuge is described in British Patent 456,420.  In the modified form the screw conveyer is made fast with the horizontal arbor for rotation therewith, and the arbor is hollowed out to pass a feed pipe which extends inwardly to a predetermined point, for example a point half way along the centrifuging bowl.  The portion of the arbor that surrounds the inner extremity of the feed pipe, and the adjacent portion of the conveyer mounting are slotted to provide communication between the feed pipe and the bowl.  In operation a slurry of the pigment is fed into the feed pipe and screw conveyer and centrifuging bowl are driven so that they rotate in the same direction. Specification 944,216 also is referred to.
