Title: Improvements in or relating to voltage measuring apparatus
IPC: G01R15/24
Filed: 1934-05-28
Abstract: 439,049. Pressure meters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and MYERS, L. M., Roseberry, Cornfield Road, Middlesbrough. May 28, 1934, No. 15881. [Class 37] An instrument for measuring high voltages comprises two quartz laminµ Q, L, cut from oppositely handed optically active crystals, on the upper and lower faces of which are electrodes (not shown) to which the voltage to be measured is applied. These laminµ are arranged between a polarizer P and an analyser A, through which a beam of light from a source S is passed. A Fresnel double-wedge compensator F is situated between the laminµ Q, L and the analyser A, the optical system being adjusted to give a black band crossing the emergent beam from the analyser. The application of a potential difference to the electrodes causes a motion of the black band across the visible field proportional to the applied voltage. The instrument may be read by means of a telescope T provided with a scale, or an image of the beam may be projected on to a translucent screen provided with a scale. Alternatively the black band may be brought back to its original position by relative motion of the wedges of the Fresnel compensator F by means of a micrometer screw. The thickness of the quartz laminµ in the direction of the electrical axis may be of the order of a millimeter, the applied voltage being of the order of 30000 volts. For higher voltages mica or similar sheets may be placed on each face of the quartz and the electrodes mounted on the outer surfaces of the mica. The polarizer P and analyser A may be Nicol prisms or simple blocks of calcite. A screen D having a horizontal slit is provided to cut off the image due to the extraordinary rays.

Title: Improvements in circuits comprising electric discharge tubes of the electron-beam type
IPC: H01J21/14
Filed: 1951-07-10
Abstract: 697,559. Thermionic valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 10, 1951 [July 13, 1950], No. 16332/51. Class 39(i) A beam from electrodes 1, 2, 3 is directed into a " cage " 9 wherein a space-charge depression of potential occurs. If the beam intensity is high the depression causes most of the electrons in the beam to be reflected to output electrode 11; if it is low, electrons can pass through the cage and reach second output electrode 10. Thus if the beam is modulated in intensity by grid 2, the space-charge effect enhances the modulation of the current collected by electrode 11 and the effective mutual conductance is thereby increased. The cage 9 is at cathode potential or slightly negative. Separate beam-forming plates may be provided.

Abstract: 801,317. Turbines. VICKERS - ARMSTRONGS (ENGINEERS), Ltd. May 16, 1956 [June 8, 1955], No. 16491/55. Class 110 (3). [Also in Group XXIX] A turbine having nozzles arranged in a plurality of groups each of which is supplied by a separate channel is controlled by a valve comprising a valve body with an inlet and outlets one for each channel and a valve member arranged between the inlet and outlets which is capable of assuming a number of different working positions and has a series of ports for co-operating with each outlet, the working position of the valve member determining which particular port, if any, in each series co-operates with its associated outlet, the arrangement being such that the different working positions connect different combinations of channels with the valve inlet. The steam inlet 22 to the turbine 21 is divided into three channels 23, 24, 25. The channel 23 leads to a group of two nozzles, the channel 24 to four nozzles and the channel 25 to eight nozzles. A valve body 27 bolted to the inlet flange 26 has an inlet 28 and outlets 31, 32, 33 leading to the channels 23, 24, 25. A hollow slightly tapered valve member 37 has four apertures 38 through which steam flows from the inlet 28 to the inside of the valve member, a first series of ports 40, 41, 42, 43 leading to the passage 31, a second series of ports 44, 45, 46, 47 leading to the passage 32 and a third series of ports 48, 49, 50, 51 leading to the passage 33. The valve member 37 has a spindle 52 supported in a bearing 55. A bush 58, in screwthreaded engagement with the spindle 52, is mounted in a conical housing 56 by bearings 61, 62. The bearings 61, 62 engage a collar 59 to prevent endwise movement of the bush 58 which is rotatable by a hand wheel 65. An extension 52A of the spindle carries a hand wheel 66 with recesses 72 which co-operate with a spring-loaded plunger 71 to locate the hand wheel in each of seven positions. In each of these positions a different number of nozzles are connected to the steam inlet. To operate the valve, the hand wheel 65 is rotated which causes the valve member 37 to move away from the boss 76 and metal-to-metal contact between the valve member and valve body ceases. The hand wheel 66 is then rotated to the desired position and the hand wheel 65 is then turned to move the valve member 37 toward the boss 76 until metal-to-metal contact reoccurs.

Title: Improvements in or relating to the joining of articles of rubber or the like
IPC: B29B15/04
Filed: 1933-06-09
Abstract: 418,762. Joining ends of rubber or like articles. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, WILLSHAW, H., and SMITH, H., Fort Dunlop, Birmingham. June 9, 1933, No. 16542. [Class 70.] In joining the ends of articles made of rubber or the like, for example, in the manufacture of tyres, tubes, treads, flaps, and protector banes, the ends are first cut and thereby provided with surfaces suitable for joining, then butt-ended together, and finally subjected to a mechanically applied consolidating pressure ; the three steps being carried out otherwise than by the inter-related operation of a single machine. Apparatus for the butting and/or consolidating operations comprises a pair of clamps 1 and 2 one of which is adapted to slide towards the other on a V-guide, clamp plates 6, 7 respectively whereof the lower is fixed and the upper is movable towards it, and a pair of linkage systems for moving the clamps, each system comprising a wing bracket 16 to the end and of which primary links 17 are pivoted, these in turn being pivoted to secondary links 18, each slotted at 19 to engage a pin 20 associated with the carrier brackets of the clamps 1, 2, and each having a claw end 21 engaging a pin 22 associated with the top clamp plates 7. Between the links a pair of toggle links 23 slotted at 24 to engage the pins 20 and pivoted together at 25 on the head 26 of a spindle 27 surrounded by a spring 30 and sliding downwardly through a door 28 to pivotal connection at the end of a cross-bar 12 carrying the wing bracket 16. The system of links at the back of the apparatus differs only in that the back secondary links 18 do not pivot into and out of engagement with the top jaws, which arrangement is necessary in the case of the front linkage in order to allow the tyre or the like to be positioned in the apparatus. The apparatus is operated by fluid pressure means controlled by a valve 11<a> worked by a foot pedal 11<b>, and comprising a piston sliding in a cylinder and operating by means of a pair of bars anchored at a pivot 15 to a rod 10 which controls both sets of linkages. On depressing the rod 10 the clamp plates 7 are first lowered on to the lower plates 6 to clamp the tube between them, and then on further downward movement the links 23 engaging the ends of the slots 24 pull the sliding clamp towards the stationary clamp so as to accomplish the consolidation of the joint. Springs 32 cause the clamps to open automatically when the pressure of the air cylinder 11 is relieved. The cylinder may be double-acting or single-acting with a spring return. Instead of fluid pressure means, other power means, manual operation, or pressure applied by a foot pedal may be employed. The cutting of the tube may be effected in the manner described in Specification 418,763. The butting of the tube ends may be effected by a preliminary hand operation if desired.

Title: Bonding metal deposits to electrically non-conductive material
IPC: C23F1/02
Filed: 1966-04-15
Abstract: In a method of improving the bonding of a metal coating to an electrically non-conductive base such as a plastic, an adhesive coating comprising a curable thermosetting resin in the A stage in a vaporizable solvent is applied to base, vacuum dried to remove all the solvent at a temperature below the resin curing point, a metal is then deposited on the dried adhesive and finally the resin of the adhesive is cured from the A stage to the C stage by heating.  The metal deposited may be Al, Cu, Ni, Co formed by vacuum deposition or by electroless deposition.  With electroless coating the adhesive is first sensitized with SnCl2 and then seeded with PdCl2.  The metal may then be electro-plated with Cu and possible further layers of Ni and Cr.  The resin layer may be cured before or after the electro-plating.  The non-conductive base may be such thermosetting resins as phenol-formaldehyde, resorcinol formaldehyde, urea formaldehyde and melamine formaldehyde, epoxy, furane, diallylphthalate, polyethylene terephthalate, and polyesters which may be reinforced with glass, asbestos and organic fibres.  The base may alternatively be steel coated with one of these resins.  These resins dissolved in a solvent such as acetone to give a solids content of 10-30% by weight may also be used as the adhesive coating. A curing or hardening catalyst, a thermoplastic resin and modifyers such as nitrile rubbers may also be included in the solution.
