IPC: G01F3/20
Filed: 1953-08-31
Abstract: 744,552. Dispensing measured quantities of liquids. PINCOTT, J. S., and HEAP, A. R. Aug. 31, 1953, No. 23965/53. Class 106(5) Metering mechanism for liquids consists of a chamber having two metering compartments 10a, 10b, Fig. 1, with an inlet 20a and an outlet 22a connected to each compartment, two spaced flexible diaphragms 12, 12a so arranged that liquid forced into one compartment expels liquid from the other, and valve means 37 arranged to admit liquid under pressure to each of the compartments alternatively and at the same time to release liquid from the other of the compartments. With the valve in the position shown, liquid flows from the inlet 20a to a pipe 15b communicating through ports 13 with the chamber 10b and from the chamber 10a, a pipe 15a and ports 43, 44 to the outlet 22a. When the valve is displaced to the right, the inlet 20a is connected to the pipe 15a via the space between sealing rings 40, 41 and the pipe 15b is connected to the outlet 22a via the space between sealing rings 41, 42. The space between the diaphragm 12a, 12 communicating through a port 32 with a cylinder 30 having a plunger 34 in adjustable screw-threaded engagement with the cylinder. Adjustment of the plunger varies the quantity of liquid between the two diaphragms and hence the capacity of the measuring chambers. The spherical radius of the diaphragms may be less than-that of the measuring chambers so that the diaphragm first contacts the chamber .around its edges to ensure complete discharge of the liquid. Small radial ribs or grooves may also be formed on or in the wall of the diaphragm or the chamber to facilitate discharge.

Title: Process for the production of stable coloured pigments having zirconium dioxide as abasis
IPC: C03C1/04
Filed: 1936-09-03
Abstract: A coloured pigment is prepared by calcining an intimate mixture of substances capable of forming two or more isomorphous salts of bivalent metals, of which salts at least one has zirconium as the metallic element of its acidic component, the acidic element of the remaining salt or salts being at least one of the other tetra-valent metals, the substances being mixed in such proportions that stoichiometric quantities of the acidic and bivalent components are present, so that the process of calcination gives rise to the formation of the said isomorphous salts, and to the final formation of clearly defined solid solutions between these isomorphous salts. The ingredients of the starting mixture may be in the form of oxides, of compounds which are transformed into oxides by calcination, or, in some cases, of the finely - divided metals themselves.  According to an example, a light grey coloured pigment is prepared by heating an intimate mixture of the oxides of zirconium, magnesium, copper and tin, in stoichiometric proportions.  Specification 384,473 is referred to.  The Specification as open to inspection under Sect. 91 describes also the preparation of coloured pigments consisting of solid solutions of two or more isomorphous zirconates, and also specifies the use of oxides of iron, cobalt, nickel, manganese, zinc, lead, cadmium, calcium, barium and strontium as ingredients in the preparation of zirconium pigments.

Title: Improvements in or relating to inspection machines for gauging the dimensions of work-pieces
Inventor: LOXHAM JOHN
IPC: G01B13/00
Filed: 1953-09-02
Abstract: 746,860. Gauging workpiece dimensions. SIGMA INSTRUMENT CO., Ltd. Dec. 2, 1954 [Sept. 2, 1953], No. 24281/53. Class 106 (2). In an inspection machine for gauging a workpiece the work is fed by a slide 2 from a loading to a gauging position, the slide being reciprocated by a motor-driven cam, a delay mechanism being provided to de-energize the motor for an adjustable, predetermined, period of time when the slide is in the loading position. A catch 13 on a lever 12 secured by a spring strip 11 to a bracket 10 on the underside of the slide 2 can swing forwardly but not rearwardly with respect to the lever 12 and co-operates with a roller 18A on an arm 18 mounted on a shaft 19 to which is also secured a wheel 20, Fig. 4. Small projections 21 and a single large projection 22 on the wheel 20 co-operate with a projection 28 on a pivoted strip 23 whose free end bears contacts 24, 25 co-operating with fixed contacts 26, 27. In the initial position the projection 22 engages the projection 28 and the motor circuit is closed via contacts 24, 26, the motor driving the cam and retracting the slide from its gauging position. When the slide is almost fully retracted the catch 13 engages the roller 18A thereby rotating the arm 18 and wheel 20 so that the projections 22 and 28 disengage, thereby stopping the motor. Rotation of the arm 18 also winds a clockwork mechanism which returns the wheel 20 to its original position but this return movement is prevented so long as the arm 18 is engaged by the catch 13. This delay period is adjustable by means of a screw 14 bearing on the lever 12. When contacts 24, 26 open a warning light is illuminated by the closing of contacts 25, 27 and this light is caused to flicker at the end of the loading delay period by the engagement of the projection 28 with the series of projections 21. Specifications 594,420, 723,793, [Group XXIX], 724,205 and 724,228 are referred to.

Abstract: 1,216,837. Fuel injection pumps. BRYCE BERGER Ltd. June 12, 1968 [May 26, 1967], No. 24615/67. Heading F1A. [Also in Division F2] In a fuel injection pump of the type in which the plunger 10 uncovers a spill port 14 to terminate injection and in which the plunger is operated by a fluid-pressure actuated piston 18 within a cylinder 19, the flow of fluid into and from the cylinder is controlled by a pressure regulator 23 that throttles the supply when the spill port 14 opens. The regulator comprises a spring-loaded movable member 35 in a chamber 30 with flow channels' arranged as shown so that the pressure difference on the ends of the member is substantially that across the chamber 30. The member has a portion of reduced cross-section and plugs 31, 32 are provided that are adjustable so that, when the spill port is closed, the member offers little resistance to fluid-flow in tunnel 34 comprising the inlet to the actuating cylinder 19, but when the spill port is open the sudden pressure drop causes downward movement of the member against the spring thus restricting fluid-flow into the cylinder 19 and thus reducing the pressure on the piston.
