Title: Improvements in or relating to thermionic valves
IPC: H01J19/42
Filed: 1932-05-02
Abstract: 401,305. Thermionic valves. WARREN, S. F., 27, Lowick Road, Harrow, Middlesex. May 2, 1932, No. 12643. [Class 39 (i).] A valve has a cathode, such as an equipotential cathode 2, surrounded by a control grid 3, a screening grid 5, an anode 4, and an external screening electrode 6, which is insulated from the screening grid and spaced laterally from one or more of the other electrodes at one or both ends, by an insulating member such as a glass bead or mica disc 11, which engages with the external screening electrode or with a support therefor, and with the other electrodes so that longitudinal movement of the electrodes is possible. The mica disc 11 is secured by metal clips 14 to a flanged metal disc 12 welded. to the electrode 6. The upper ends of the electrodes 2, 3, 5 pass freely through the mica disc 11. The metal disc 12 has a central aperture to prevent contact with the electrodes 2, 3, 5. A similar mica disc and metal disc may be secured to the other end of the electrode 6, or the electrodes 2, 3, 5 may be spaced by a mica disc 16 secured to a metal cap 15 attached to the screening grid 5. The electrode 6 may be insulated from all the other electrodes, but is preferably connected with a point of low potential such as the cathode, or earthed. The metal disc 12 may be connected with the screening grid 5 and insulated from the electrode 6. The anode may be of perforated metal or of grid form. A similar construction may be applied to a pentode in which the external screening electrode is connected with a suppressor grid by an annular plate as described in Specification 401,296.

Abstract: 604,187. Electric control systems. TUSTIN, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 2, 1941, No. 12768. [Class 40 (i)] ralso in Group XXXVII] A. " joy-stick " has pairs of arms 11, 12 and 15, 16 rigid therewith and radiating from the centre of rotation thereof. These pairs of arms are journalled' respectively in lower and upper semi-ellipsoidal members 5, 8, which are connected by shafts 4, 7 to controller 2, 3. Movement of the stick 1 to the left causes rotation of the member 8 and controller 3, the arms 11, 12 freely rotating in, the member 5. Movement in other directions causes similar operation of either or both the controllers 2, 3. The controllers 2, 3 may be of a " follow-up " type, and they may control the displacement of a power-driven gun in elevation and in azimuth. The control effected may be of the type disclosed in Specifications 577,309, 577,315, [both in Group XXXVII], and 604,186.

Title: Improvements in or relating to printing compositions
IPC: C09D11/10
Filed: 1932-05-04
Abstract: Resins for use as an ingredient of viscous, quick-drying printing-compositions are prepared by heating together a polyhydric alcohol, a polybasic acid, and drying or semi-drying oil acids, or by heating the alcohol and oil together until a single phase is formed, and then adding the acid and heating until resinification occurs. The resins preferably contain 40 to 85 per cent of oil or oil acids, those containing below 55 per cent being suitable for use in printing-enamels, and those containing more than 55 per cent being suitable for use in inks.  The resin may be formed from glycerol, glycol, pentaerythritol, mannitol, or a polyglycol, and phthalic, succinic, malic, maleic, fumaric, tartaric, or citric acid.  The viscosity can be varied by altering the time and temperature of the reaction.  According to examples printing-ink resins are prepared (1) by heating together phthalic anhydride, glycerol, and linseed oil fatty acids in the presence of carbon dioxide until an acid number of not more than 10 is obtained; (2) by heating together in an atmosphere of carbon dioxide a mixture of glycerol and caustic soda with linseed oil until a sample is clear, and then adding phthalic anhydride until an acid number of 5 is obtained; and printing-enamel resins are prepared (1) by heating together phthalic anhydride, glycerol, linseed oil acids, and china wood oil until an acid number of 37 to 42 is obtained, the mixture being then thinned with naphtha and centrifuged; (2) by heating together glycerol, linseed oil, and p china wood oil, adding a mixture of linseed oil and litharge, heating until the mixture is clear, adding phthalic anhydride, heating until an acid number of 35 to 40 is obtained and finally thinning with naphtha and centrifuging.

Title: An improved dimension indicating and control device, for use with surface-conditioning mechanism for wire or the like
IPC: G01B13/08
Filed: 1945-05-23
Abstract: 600,941. Wire dimension control devices. VAUGHN MACHINERY CO. May 23, 1945, No. 12910. Convention date, April 7, 1944. [Class 60] [Also in Group XIX] A device for controlling the dimensions of a piece of wire, rod or tube which is being surface conditioned comprises a fluid pressure chamber with aligned openings gauged to fit the work piece, as it moves through with a desired cross-section, with a predetermined close clearance, and means to stop the movement of the work upon its excessive frictional contact with the said openings. An axially moving wire W oscillated by gripper rolls passes between two overlapping and axially adjustable grinding wheels 6 and 7 and thence through a dimension control device. This device comprises a housing 20 into which is fitted a tubular member 22 having dies 23 secured in its ends through which the wire W passes. Reciprocably mounted in the housing 20 is a latch 26 engaging an encircling V-shaped groove 25 round the middle of the member 22, so that if the wire comes through excessively thick the frictional contact pulls the member 22 along and raises the latch 26 to switch off the whole machine. A fan 31 supplies air through an orifice 33 and radial apertures 29 to the interior of the chamber 22 where it normally leaks out through the clearance between the wire and the dies 23. If the wire is too thick as it comes through, the clearance is reduced and a pressure is built up inside which is transmitted through a channel 34 to an indicator 35 and through a channel 34a to a weighted diaphragm 38 to close a micro switch 37. This switch is in a circuit which includes a solenoid with a pawl 46 which operates a ratchet wheel 45 and a timing relay. The ratchet wheel 45 is mounted on a shaft 41 geared to a threaded shaft 40 which moves a grinding wheel in an axial direction towards the wire. The work piece may be rotated or oscillated bodily. Specification 592,825 is referred to.

Abstract: 569,981. Locking rods. MILES AIRCRAFT, Ltd., (formerly PHILLIPS & POWIS AIRCRAFT, Ltd.), and HOPKINS, F. T. Aug. 11, 1943, No. 13012. [Class 80 (iii)] A rod 3 is locked to a member 1 by balls 8 located in longitudinal flutings 9 formed either in a conical bore 2 of the member 1 or in the shaft 3. The flutings are of part cylindrical formation in cross-section. The balls 8 are urged to locking position by a spring-pressed sleeve 4 slidable on the shaft and which may be splined to either member 1 or 3. The balls may be caged, and the cage may form part of the sleeve 4. The part 1 or 3 not having the flutings may have an annular groove to provide positive looking. Means may be provided to prevent relative rotation of the parts 1, 3, 4. To release the lock the sleeve 4 is moved against the action of its spring 6. Such movement may be effected by an electrical solenoid.

The switchmeans comprises a base-plate 19 secured to the brake pedal by pliable metal tongues 22. One contact plate 24 is insulated from the. base-plate. and the second contact plate 32 is carried by leaf springs 31. Pressure of the foot on the flexible cover 21 establishes contact to operate the signal, which comprises a cylindrical casing with an aperture illuminated by an internal electric lamp, the casing being adjustably carried on a bracket such as shown in Fig. 10. A segmental cylindrical screen bearing the word " slow " is mounted on the spindle 4, which at one end is provided with a laminated armature 5 having a bi-polar winding 6, the ends of which are connected to semicircular plates 7 insulated from the spindle 4. Bearing on the plates 7 are brushes connected to the wires of the circuit containing the switch member. A laminated iron field coil 9 with field coils 10 is fixed to the casing and surrounds the armature, from which projects a pin 11 moving between stops 12 stamped up from a partition 13. Closure of the switch thus causes the armature to rotate against the action of a spring until the pin comes against one of the stops.
