Title: Improvements relating to apparatus for gauging dimensions of workpieces
Inventor: FOSTER EDWARD HERBERT
IPC: G01B5/00
Filed: 1959-04-13
Abstract: 895,154. Gauging departure from standard form. ROLLS-ROYCE Ltd. April 6, 1960 [April 13, 1959], No. 12530/59. Class 106 (2) [Also in Group XX] Apparatus for gauging dimensions of a workpiece W comprises a table 10 provided with a plurality of indicia 18 equally spaced angularly, a pivoted bar 20 which may be clamped in any angular position, a support 25 sliding on the bar and capable of being clamped to it, and a universally movable probe 62 carried by the support 25. Angularly spaced around the table 10 are six slots 11 in which slide locating bobbins 12. These may be clamped in any desired position. The indicia consist of a number of holes 18 angularly spaced every ten degrees and the bar 20 is pivotally mounted on a pin 17 in the centre of the table. The bar may be clamped by use of a strap 22. Sliding on the bar 20 is a T-piece 25 which can be held in one of a number of positions by pins inserted in two holes 27 and so fitting into holes 21 formed in the bar. The T-piece 25 carries a slidable height bracket 30 which can be held in position by clamps 32. Alternatively, this bracket can be mounted directly on the bar 20. A member 35 slides on the bracket and can be held at a number of fixed heights. A bar 54 is mounted on the member 35 and can be fixed in any desired angular position. It also carries an angularly adjustable block 56 in which fits a bar 62 having a dial gauge 64 mounted at its end. For setting purposes, the bar 62 may be replaced by a bar having a ball fixed at its lower end. The workpiece W is mounted centrally on the bobbins 12 and the apparatus can then be adjusted, by the use of slip gauges, to measure various dimensions of the workpiece, or for example, to check the concentricity of the tubular member 71. In the example described, the workpiece has a dowel hole 70, Fig. 3, in its flange 68. This is used to provide an angularly positioned datum line. The bar 20 is rotated until its centre line is in line with one of the holes 18. A dowel pin 83 (Fig. 3) is inserted in the dowel hole 70 on the workpiece and is aligned with the centre line of the bar 20 by fitting a bridge piece 80 on the bar and using suitable slip gauges 84. The workpiece is then clamped and the bar set to a position parallel to the axis of the tubular member 71. The angular movement required is obtained from the working drawing and a peg inserted in a suitable hole 18, spaced from the dowel hole by an angle slightly less than that required. The remainder is then built up using slip gauges.

Title: Improvements in regulators for the pressure of fuel supplied to internal-combustion engines
IPC: F02M69/00
Filed: 1931-05-01
Abstract: 382,948. Spray carburetters; regulating ; valves. SOC. GENERALE DES CARBURATEURS ZENITH, 10, Rue Petitot, Geneva, Switzerland. May 1, 1931, No. 12934. Convention date, May 1, 1930. [Classes 7 (iii) and 7 (vi).] The pressure of the fuel supplied to an engine or carburetter is regulated by a valve attached to a deformable membrane loaded by a weight and a spring jointly. Fuel entering at 1 passes a valve 4 to a chamber 2, one wall of which is constituted by a membrane 9 loaded by a weight 13 and spring 11. The upper surface of membrane 9 is subjected to atmospheric pressure through vent 19, or to the reduced pressure in Venturi 8 through a duct 20 and calibrated orifice 21. Fuel from chamber 2 passes to a jet 14 in a well 15 open to atmosphere at 16, the aerated fuel being discharged into the Venturi through a nozzle 6. The weight 13 is stated to balance the liquid head b between the membrane and the jet 14 at all inclinations of the apparatus, but a balance may be effected only in a given vertical plane, e.g. the longitudinal plane of an aeroplane. The spring, on the other hand, balances the head a between jet 14 and outlet 6 when the apparatus is horizontal and exerts a constant pressure on the membrane whatever the inclination. In a modification, in addition to the membrane 9, two other membranes are attached to the valve in order to balance the effect of the fuel pressure on the inlet face of the valve which is connected through a lever to the spindle attached to the membranes. The Specification as open to inspection under Sect. 91 describes also a construction in which (1) the membrane is loaded directly by a weight only, (2) the membrane is loaded by a weight at the end of a lever which actuates the valve, and (3) two membranes are connected together by a rod which actuates the valve through a lever the jet being placed above the membranes in line with the rod. This subject-matter does not appear in the Specification as accepted.

Abstract: 140,656. British Thomson - Houston Co., (General Electric Co.). lay 23, 1919. Regulation, automatic systems and apparatus for; systems depending on the use of two or more machines. - In electric systems of power transmission comprising a main source of alternating current and a supplementary source, automatic regulation is effected by means which raise or depress the voltage furnished by the main source of supply in response to changes in the power-factor of the load, while the supplementary source is connected direct to the distribution circuit. One arrangement of this kind comprises an induction regulator 15 inserted in three phase lines 13 fed from a generator 2, there being also a supplementary generator 5. A powerfactor relay 20, responsive to a coil 26 excited conjointly by a series transformer 28 and a potential transformer 27, closes contacts at 22 or 23 according as the power-factor increases or decreases. This causes a reversible electric motor 17 geared to the induction relay 15 to revolve in such a direction that the voltage of the lines 13 is raised or depressed until the desired powerfactor is restored. The supplementary generator 5 is maintained at approximately constant voltage by a regulator 10.

Title: Improvements in the determination of the gas content of liquid metals
Inventor: RANSLEY CHARLES ERIC
IPC: G01N33/20
Filed: 1950-05-25
Abstract: The content of hydrogen dissolved in a molten metal (e.g aluminium) is measured by causing a free surface of the metal to form within the body of the metal, and determining the equilibrium pressure of molecular hydrogen which develops at this surface.  In the apparatus shown in Fig. 1, a palladium tube 2 closed at one end and <PICT:0684865/III/1> <PICT:0684865/III/2> protected by a sheath 8 of porous material, e.g. sintered alumina, is connected to a copper tube 5 surrounded by a protective steel tube 7; the tubes are evacuated through pipe 10 and the palladium tube is then immersed in the metal; hydrogen diffuses through the walls of the tube 2, and from the pressure indicated by manometer 6 the hydrogen content of the metal is calculated.  The tube 2 may be made of other substances (e.g. nickel, iron, or refractory material) which are pervious to hydrogen but impervious to the metal.  In a modified form of the diffusion head, Fig. 2, (not shown), one or two palladium discs are mounted in a steel disc or annulus.  Before using the apparatus an inert gas, e.g. argon, may be bubbled through the porous protective sheath in order to remove air; in this case the device of Fig 1 is modified by providing an annular space around the palladium tube for the inert gas, Fig 3 (not shown).  A Bourdon tube may be used in place of the manometer, or the diffusion head may be provided with a flexible wall, the movement of which indicates the pressure.  The diffusion head shown in Fig. 5 comprises a platinum filament 51 surrounded by a porous ceramic cover 55; the filament is connected through copper tube 49 and copper lead 48 to an electrical bridge circuit, whereby a current is passed through the filament and its resistance is measured; the decrease in resistance indicates the pressure of hydrogen diffusing through the porous cover 55; inert gas is supplied through valve 58 and tube 49.
