Abstract: 937,334. Gauges; indicating algebraic errors. ROLLS-ROYCE Ltd. April 5, 1962, No. 13227/62. Classes 106 (2) and 106 (4). A gauge for indicating the algebraic sum of errors for measurements made simultaneously at a number of locations on a workpiece (e.g. to assess the throat area accuracy of a nozzle guide vane of a gas turbine engine) comprises fixed and movable feelers 12-19, the movable feelers 13, 14, 16, 17 and 18 being pivotable (as shown in Fig. 3) to cause axial movement of an associated slider rod through a pin-andslot connection. The slider rods are integral with blocks carrying gears 44, 42, 41, 47 and 48, respectively, which on displacement impart rotation through the gear train 41-51 to give an algebraic sum of movement to a rack 40 indicated on the dial gauge 34. In another embodiment displacement of the feelers rotates the associated gears. An abutment member 84 locates the workpiece true.

Non - contact - making relays. - A relay comprises a variable resistance formed bv separating two portions of an electrolyte by an insulating partition containing a restricted passage adapted to be varied by the movements of a moving coil. The resistance may be of any of the forms described in Specification 134,865. A pair of vanes 13, 14 carried by an arm on the spindle 12 of a moving-coil galvanometer moves in front of small apertures 9, 10 in a diaphragm 10 which separates the electrolyte in two compartments 1, 2 from that in a third compartment 3. Electrodes 6, 7, 8 are arranged in these compartments. Movement of the vanes 13, 14 varies the ratio between the resistances of the apertures 9, 10 and thus causes energization of a coil 11 connected between the electrode 8 and. the middle point of a battery B. According to the Provisional Specification, a vertical strip of material may be moved transversely to vary tha size of the opening in the diaphragm.

The valve member 11 is loaded axially by a spring 20 and/or by fluid pressure to maintain the roller 15 in contact with the bore 15 and resist axial displacements of the valve member 11 consequent upon rotation of the member 11 in the sleeve 10.
Patent GB-456581-A (GB)
Title: Method for the production of a dispersion of a gas in a liquid
IPC: B01F3/04
Filed: 1935-05-08
Abstract: <PICT:0456581/III/1> Relates to a method of producing fine dispersions of gases in liquids, for obtaining aerated liquids, emulsions, or dispersions of gases in solids, or for effecting chemical reactions such as oxidations or reductions.  The gas is dispersed in the liquid in a state of rarefaction of from ,01 to ,001 atmospheres, and the state of rarefaction is then removed.  The gas, already rarefied, may be dispersed in the liquid medium, or it may be dispersed in the vapour of the latter, which is then condensed; or it may be rarefied with another gas which is soluble in, or can be condensed to a liquid miscible with, the liquid dispersing medium. As shown in Fig. 1, the liquid dispersing medium in a container 2 is circulated, by a pump 8, through a path which includes a jet pump 7. The latter draws in the gas to be dispersed and vapour of the liquid medium from the sources 3, 1 under the control of valves, not shown. In a modification, the liquid is circulated by a rotary pump, and the gas and vapour are supplied to the centre of the rotary system.  In another modification, Fig. 4, the liquid medium is passed from 9 to 2 by a pump 8 and a jet pump 7 which is so operated that the liquid is converted to its vapour isothermally.  The gas to be dispersed is drawn into the jet pump from 3 under control of a valve or capillary restriction.  In modifications of this form, the jet pump is replaced by a rotary pump.  In other modifications, gas at reduced pressure is produced electrolytically, or is subjected to ozonizing or other electrical treatment before dispersion.  The dispersed systems produced as described may be stabilized by protective colloids, &c., and may be maintained under increased pressure.  To obtain dispersions of gases in solids, for example plastics, the gas is dispersed while the solid is in molten or dissolved condition. Similarly, emulsions may be obtained if the gas, after dispersion in the liquid medium, is itself condensed.  Specifications 22666/01, [Class 14], and 286,316, [Class 1 (i)], are referred to.

Abstract: 229,913. Bauerle, T. June 4, 1924. Striking-mechanism. - In a striking clock of the Westminster chiming type, the gearing to the hour and quarter-hour striking-mechanism is so arranged that one revolution of the gathering pallet i strikes two hour-strokes but only one quarter-peal, the common rack g being moved through double steps for each quarter peal. The quarter-hour cam b on the minuteshaft operates a lever r having slips s<1> - - s<3> twice as deep as the hour-steps e, which engage a stop t on the rack for the first, second and third quarter peals. On the fourth quarter the lever r is raised out of the path of the projection t and the rack contacts at f with the hour-cam to permit the striking of the four quarter-peals followed by the hour striking, say 8 o'clock. The stop t may be replaced by a catch engaging the quarter-hour cam which would be of reversed construction to that shown and should allow contact between the rack pin f and the hourcam e at the fourth quarter.

Title: Improvements in or relating to fluid pressure operated apparatus for moving a tool towards a workpiece
IPC: F15B13/04
Filed: 1959-04-22
Abstract: 920,704. Valves. BALDWIN INSTRUMENT CO. Ltd., and C. H. HAY. April 22, 1960 [April 22, 1959], No. 13742/59. Class 135. Fluid-pressure operated apparatus, e.g. an automatic drilling machine in which a feed movement is effected when a signal pressure at 19, Fig. 1, is applied to a pilot piston 13 operating a control valve 21, has pressure equalizing means equalizing the pressure on both sides of the piston when it is moved a predetermined distance and means to restore these means to their inoperative position. The signal pressure acts on the piston via openings 33, 34 in the hollow stem of the piston controlled by a valve 38, and shifts the valve 21 through a spring 26. When the valve 21 is fully to the left, as in Fig. 4, the spring is compressed slightly and the lost motion, between a cross-pin 28 on the valve and a hole 27 in a piston spigot 25 engaging the spring, is taken up so that the pin engages a spigot 39 on valve 38 which moves to shut off signal pressure to the piston via 34 and allow the pressure to pass sealing ring 44 and land 36 to act on piston 37 which moves against spring 43 to connect both sides of the piston via openings 34, 46 to atmosphere at 20. The valve 21 and piston can then be moved in the reverse direction by pressure acting on plunger 24, while signal pressure is still on at 19. Cutting off signal pressure allows valve 38 to return to its initial position. In a second embodiment a single landed axially bored valve 38 balances the piston with signal pressure on both sides.

Abstract: 110,001. Hutchinson, E. Oct. 3, 1916. Spray carburettors.- In a carburettor involving a fuel nozzle situated in alinement with a piston throttle valve c, Fig. 1, which is moved transversely across the straight-through induction passage, additional air is admitted to the mixture outlet side d of the induction passage through a conduit controlled by the throttle valve. The conduit may be outside the throttle casing as shown at a, Fig. 1, or it may be formed in the throttle as shown at g, Fig. 3, or bv cutting away the periphery of the throttle. The conduit may be independently adjustable. In a modification, a passage connects this conduit with the space above the fuel nozzle. In a further modification, the additional conduit is separate from the throttle casing and has inlet apertures controlled by a piston or sleeve valve actuated from the throttle valve. A by-pass for mixture between the jet chamber and mixture outlet may be formed by leakage past the connexion of the Bowden wire to the throttle, or through a keyway provided to prevent rotation thereof. The throttle may contol the ports by which the air enters the space above the throttle instead of or in addition to the control described above.
