IPC: B21H1/14
Filed: 1924-09-09
Abstract: 240,623. Marks, E. C. R., (Hollow Ball Co., Inc.). Sept. 9, 1924. Hollow balls.-In the manufacture of a ball from a length of metal tube by closing in the ends by hemispherical dies, the holes are finally sealed by rolling the surrounding metal. The ends 11, Fig. 3<a>, of the tube are first tapered and then shaped by the dies A to produce a ball with two holes. This is placed successively in corresponding circular grooves 1, 7, Fig. 4, in discs 20, 2, the former being rotated by hand or power and the latter fed downwards, the pass being indicated by a scale 5. The first acting grooves 1 have their deeper portions b - - b, Fig. 6, cut to a radius equal to that of the finished ball, e.g. 0.625" about centres d, and their outer portions a - - b flared out, e.g. radius 0.685". The finishing grooves 7 have the radius of their cross section greater than that of the balls.

Filed: 1958-07-04
Abstract: 865,957. Voltage measuring. STANDARD TELEPHONES & CABLES Ltd. July 4,1958 [July 5, 1957], No. 21474/58. Class 37. An electroluminescent voltage indicator, in which the size of a luminescent area varies with the magnitude of an applied voltage, comprises a layer 4 of electroluminescent substance lying between a conductive layer 2 and a resistive layer 3; a voltage to be measured being applied between the conductive layer and one edge of the resistive layer. A transparent conductive layer 2, of SnO or TiO, is disposed upon a transparent glass or mica base 1 and is partly covered with an electroluminescent layer 4 of zinc sulphide, with a copper activator, dispersed in a poly-acrylic acid ester dielectric, the remaining portion of layer 2 being covered by a metal strip 10<SP>1</SP> of silver or indium. A resistive layer 3 of aluminium or graphite overlies the layer 4 and is connected by conductive strips 9 to terminals 10 on an insulating lamina 11; the voltage to be measured being applied between the strip 10<SP>1</SP> and the two outer terminals 10, the centre terminal 10 being connected to strip 101 through resistor 7. Increase in the applied voltage causes the luminescing area of layer 4 to progressively extend from the outer strips 9 towards the centre strip. Variation of the resistance 7 enables the size of the luminescing area to be adjusted for a given applied voltage. In a modification, a layer of material having a resistance which decreases with increase of an applied voltage is inserted between layers 3 and 4 to provide a sharper demarcation line between the luminescing and non-luminescing portions of layer 4. In a further modification, Fig. 10 (not shown), a digital voltage indicator is provided by a plurality of electroluminescent units interconnected by resistors so that an increasing number of units luminesce with increase of the applied voltage.

IPC: C25D11/04
Filed: 1950-09-01
Abstract: 702,742. Saw tooth generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 4, 1951 [Sept. 1, 1950], No. 21602/50. Class 40 (6) In a saw tooth generator comprising a driving valve and a damping valve coupled to a reactive output circuit and having control grids fed from a phase splitter supplied with timing pulses, a resistor in series with a capacitor is connected in a feedback circuit between the output circuit and the input of the phase splitter and so arranged that the capacitor is charged during the flyback and subsequently slowly discharges to produce a linear forward stroke. The timing pulses from a blocking 0 are applied through a phase splitter V1 to cut off the anode current in driver valve V2. The point Y in the output circuit accordingly swings to a high positive potential and charges a feedback capacitor C5. At the end of the flyback the capacitor discharges slowly through an amplitude adjusting resistor R5 producing a decreasing voltage at the grid of a damping valve V3 and an increasing voltage at the grid of the driving valve. The path through the capacitor provides negative feedback during the forward stroke. The capacitor may alternatively be connected to the anode of the driver valve or, as in Fig. 3 (not shown), to the anode of the damper valve, though in the latter case the capacitor is charged in the opposite polarity and the connections in the input and phase changing circuits must therefore be reversed.

Abstract: Khaki prints are obtained using a paste containing a dyestuff made by coupling diazotized 1 - amino - 2 - methyl - 5 - nitro - or - 2,5 - dihalogenobenzene with 1 - (31 - hydroxydiphenylene oxide - 21 - carboylamino) - naphthalene and Example (2) describes a paste prepared from the diazo component 1-amino2,5-dichlorobenzene, an aqueous emulsion of a copolymer of vinyl acetate and butyl acrylate, an ammoniacal solution of a condensation product from urea, formaldehyde and ethylene glycol, tragacanth thickening and ammonium hydroxide and thiocyanate solutions.  Specification 426,564, [Group IV], is referred to.ALSO:In a dyeing or printing process a dyestuff is used which is obtainable by coupling diazotized 1 - amino - 2 - methyl - 5 - nitro - or - 2, 5 - dihalogeno - benzene with 1 - (31 - hydroxydiphenylene oxide - 21 - carboylamino) - naphthalene.  Khaki dyeings or prints are produced on fibrous materials especially those composed of vegetable fibres, e.g. cotton and viscose, which give infra-red photographs exhibiting effects similar to those of chlorophyll and may thus be used for camouflage purposes.  In examples (1) a cotton fabric is impregnated with a solution containing 1 - (31 - hydroxydiphenylene oxide - 21 - carboylamino) - naphthalene, soda - turkey red oil, alcohol and caustic soda and the dried fabric is treated with a solution of a stable diazonium compound of either of the above amines adjusted with partially dehydrated aluminium sulphate (and also sodium naphthalene - 1,6 - disulphonate when the 5 - nitrobenzene derivative is used) passed through air at 30 DEG C. and sodium carbonate solution then rinsed and soaped at the boil and in (2) the coupling component in aqueous caustic soda solution containing ethanol is treated with diazotized 1 - amino - 2,5 - dichlorobenzene, the dyestuff isolated and made into a printing paste for cotton or viscose containing an aqueous emulsion of a copolymer of vinyl acetate and butyl acrylate, ammoniacal solution of a condensation product from urea, formaldehyde and ethylene glycol, tragacanth thickening and ammonium hydroxide and thiocyanate solutions.  The dyestuffs may also be produced on the fibre by usual printing processes such as those using an antidiazotate or a water-soluble diazoamino compound of one of the two amines together with the azo component with subsequent colour development or the naphtholate or base printing process may be used.

[Also in Group XIX] Two or more plane section profiles of a body of which images are projected optically simultaneously are each defined by the image, formed on the body, of an illuminated mask shaped generally to suit the shape of the associated section profile so as to ensure a reasonably sharp image on the surface of the body. In the form shown in plan, Fig. 12, three slits F are each illuminated by a system comprising a lamp H and lens system H<SP>1</SP>, H<SP>2</SP>. Three image forming systems each comprise lenses E<SP>3</SP>, E and E<SP>2</SP>, the three lenses E<SP>2</SP> being mutilated to allow their juxtaposition, with axes vertical, above a mirror E<SP>1</SP>. Images are thus formed on the underside of the object A, a turbine blade, to define sections A<SP>1</SP>, A<SP>2</SP>, A<SP>4</SP> for projection in the direction of the length of the blade by a system such as described in Specification 727,899. Three other optical systems, similar to those shown, are located above those shown and project downwards on to the object. Each pair of systems may make use of a common lamp H by means of inclined mirrors H<SP>6</SP>. Rhomboidal prisms E<SP>4</SP> permit the illuminated sections to be closer than the slits F. Two of the systems are laterally movable, to change the spacing of the illuminated sections, on guides E<SP>5</SP>, H<SP>4</SP> on which they are located by distance pieces E<SP>6</SP>, H<SP>5</SP>. To complete the change, the plate G, carrying the slits F, is exchanged for another with slits at a different separation. The plate slides in guides G<SP>1</SP>. The individual slits, as shown in vertical section in Fig. 4, are carried in flanged cylindrical housings F<SP>1</SP>, each retained in a hole in the plate G by a nut F<SP>2</SP> and prevented from rotating by a pin F<SP>3</SP>. The slit is formed between the edges of two members F<SP>6</SP> each held by screws F<SP>7</SP> and'so shaped in an axial plane containing the slit, that a sharp image of the slit is formed at all points of the illuminated sections. The slit may be replaced by a line on a transparent member or through an opaque coating on such a member. In a modification the illuminating and image-forming systems are fixed and movable reflecting prisms determine the positions of the illuminated sections. In another modification only the slits and illuminating systems are moved for this purpose. Specification 707,155 also is referred to.
