Title: Three-position ram
Inventor: AUDSLEY ALAN KEITH
IPC: F15B15/24
Filed: 1968-02-09
Abstract: 1,216,546. Three positions pneumatic ram. PATERSON CANDY INTERNATIONAL Ltd. Feb.4, 1969 [Feb.9, 1968], No.6458/68. Heading F1P. The output pistons 5 of a ram having two extreme and one variable intermediate positions is elevated by fluid-pressure applied at 13 or depressed by pressure applied between the piston 5 and an auxiliary piston 4 through a bore 14. The intermediate position is determined by adjustable stop 15 and attained when pressure is equally applied via 13 and 12. Instead of relying on gravity to position piston 4, it may be of larger effective area (by increasing the diameter of rod 7) to produce a similar bias.

Title: Apparatus for thickness measurement
IPC: G01B7/06
Filed: 1972-02-11
Abstract: 1436698 Measuring thickness capacitatively BAKELITE XYLONITE Ltd 11 May 1973 [11 Feb 1972] 6493/72 Heading G1N In apparatus for measuring the thickness of dielectric sheets 9, three electrodes are provided, electrode 1 and electrode 2 having co-planar surfaces 6 and 7 and electrode 3 being provided between electrodes 1, 2 for screening these electrodes at parts not adjacent the co-planar surfaces, and means are provided for either maintaining the sheet in contact with the surfaces 6, 7 or a substantially fixed distance above the surfaces 6, 7. Electrode 1 is connected to a source of A.C., electrode 2 to measuring circuitry and electrode 3 to earth. The electrodes may be planar, as shown, or cylindrical, Figs. 3 and 4 (not shown). A second measuring electrode (2') and a second screening electrode (3') may be provided, Fig. 5 (not shown). The electrodes may be mounted in an earthed casing. The sheets may be stationary or continuously passed over the electrode system during measuring. The sheet is maintained in contact with surfaces 6, 7 by mechanical means or the sheet is electrostatically charged, or the electrode system is provided with holes through which air is drawn. To maintain the sheet a fixed distance above the surfaces 6, 7 gas is blown through holes in the electrode system. An amplifier in the measuring circuitry may contain filter circuits and its output is rectified to provide D.C. to a moving coil meter. Alternatively, the amplifier may include a synchronous rectifier. The current which flows through the amplifier when no sheet is present can be neutralized by feeding to the amplifier an A.C. which is of the same frequency and amplitude, but which is in anti-phase relationship. This current may be derived, via a capacitor from the A.C. energizing source of electrode 1. The current or voltage gain of the amplifier may be stabilized to be independent of temperature variations.

Title: Improvements in and relating to exothermic welding
Inventor: WHITCHURCH DONALD ROLAND
IPC: B23K35/34
Filed: 1962-02-21
Abstract: An exothermic welding powder comprises cuprous oxide and aluminium as major constituents, the ratio of the cuprous oxide to aluminium being between 7 : 1 and 8 : 1 by weight. Minor constituents may be silica, magnesium, ferric oxide, or up to 3% by weight of potassium nitrate. Preferably the particle sizes are such that the cuprous oxide will pass through a 200 mesh sieve, and the aluminium being coarser would leave a major proportion on a 200 mesh sieve.  The powder may be packed in a cardboard carton furnished at its base with a steel or iron plate, or a copper disc with an oxide-free surface.  A conductor may be joined to a cast iron pipe by placing a carbon mould containing the carton over the end of the conductor, which has been placed on the iron pipe, and igniting the powder.  The plate or disc at the bottom of the carton melts and runs on to the conductor welding it to the pipe. An igniting powder may contain magnesium, which itself may be ignited by a firework starter, e.g. paper impregnated with KNO3.

Title: Improvements relating to automatic voltage control equipment for electrical alternators
Inventor: CHICK DOUGLAS RICHARD
IPC: H02P9/26
Filed: 1951-03-21
Abstract: 692,379. Automatic voltage control systems. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Feb. 13, 1952 [March 21, 1951], No. 6776/51. Class 38 (iv). The voltage of an alternator is maintained constant by a motor-generator set having one part (either motor or generator) connected as a variable impedance in the field circuit, and the other part responding to the error voltage. As shown, the alternator output is rectified at D1, D2 and applied through a potential divider to the grid of one half V1 of a double triode having a glow-lamp N providing a constant reference voltage at the grid of the other half valve V2. (The rectified voltage also provides the H.T. supply for these valves.) The error voltage output from the double triode is fed to an amplifier V3 which loads the generator G of the motor generator set to cause the motor M to act effectively as a variable impedance in the alternator field supply. A magnetic amplifier may be used instead of a thermionic valve.

Abstract: 106,308. Walker, J. J., and Walker, J. H. P., (trading as Walker & Sons, J. W.). May 15, 1916. Drilling.-Jigs for use in drilling articles such as the bosses of aeroplane propellers, in which the holes are required to be drilled in part from one face and in part from the other, employ locating means situated at a distance from the centre of the plates. Plates a, Fig. 1, are positioned by holes j engaging a spindle passed through the boss and are registered by bars e. After fixing the plates to the work by screws passing through the holes d, the bars are removed for use in setting other plates. In a modification, circular plates have means for engaging radial arms formed with an eye at one end to receive the spindle passed through the boss and split at the other for clamping to a bar such as e. In a further modification, the arms are split at each end and provided with adjustably positioned registering pins engaging holes in the plates. Instead of passing the drill through the holes in the plates, the plates may be used to locate a frame 1, 2, 3, Fig. 5, by means of a pin 6 carried by an adjustably clamped slider 4, a second slider 5 adjustable by a screw 9 and nuts 10 carrying a brush 8. The plate is provided with more than one row of holes and is notched at 12 to allow the drill to operate close to the inner row. The Provisional Specification describes a method of working with one jig plate only and with a " feeler-hole " through the boss instead of the finished bore.
