Title: Improved manufacture of coated articles
IPC: B05D7/26
Filed: 1944-06-28
Abstract: A base member is coated by contacting the surface with a composition comprising an organo-silicon compound selected from the class consisting of hydrolysable organo-silicanes, their hydrolysis products and their polymerized hydrolysis products, and thereafter applying to the treated surface an organic coating composition. Hydrolysable organo-silicanes are defined as derivatives of silicon hydride which contain readily hydrolysable radicals such as halogen, amine groups, alkoxy, aroxy and acyloxy radicals, the remaining valencies of the silicon atoms being satisfied by organic radicals that are joined to the silicon atoms through carbon atoms; there are specified phenylsilicon trichloride, methallylsilicontrichloride, phenyldimethyl siliconchloride, benzyl-silicontrichloride, paradimethylaminophenyltriethoxy silicane, phenylethylsilicane diol, diphenyl silicane diol, methyl silicone, ethyl silicone, propyl silicone, butyl silicone, phenyl ethyl silicone, phenyl methyl silicone and phenyl silicone.  The primary coat may be applied by dipping or by spraying with the liquid pouring agent or its solution, or by exposing the base to the vapours formed by heating or by blowing air or steam through the priming agent. The base may be reheated after this treatment to a temperature below the boiling point or decomposition temperature of the compound used.  The organic coating composition may be a plastic, a resin, a lacquer, a dye or a cement.  Preferred base members are those of siliceous composition although metals may be used.  In examples, a glass plate is treated with phenyltrichloride in benzene and (1) glass fibre tape cemented to the treated plate with polymethylmethacrylate (2) coated with an ethyl cellulose-manilla gum lacquer and baked (3) coated with a polystyrene benzene solution and baked (4) coated with polymethylmethacrylate-dioxan solution and baked (5) coated with a cellulose nitrate lacquer (6) coated with an ethyl cellulose-isopropyl alcohol solution and baked (7) coated with a cellulose-acetate-acetone solution and baked (8) coated with a poly-propylmethacrylate-benzene solution and baked (9) coated with a vinyl acetate vinyl chloride copolymer in a mixture of benzene and dioxan and baked.  In further examples (10) Borosilicate glass plates are treated as in (1) and then coated with a drying oil varnish and baked (16) a glass beaker is treated as in (1).

Filed: 1939-04-27
Abstract: 528,130. Aircraft windscreens. REID & SIGRIST, Ltd., and BOWER, C. April 27, 1939, No. 12680. [Class 4] A streamline cabin or cockpit cover comprises a movable door part normally in continuous contour with a fixed part of substantially the same sectional shape and mounted so that it can be moved so as to enter into and slide, within the fixed part, the door being'adapted to be deformed so as to contract in breadth and mounted so as simultaneously to be dropped relative to the fixed part enabling it to slide therein. As shown in Fig. 3, the cabin top comprises a windscreen 1, door 2 and fixed portion 3 constructed of light metal framework 8 panelled with transparent material 9. The door 2, Fig. 4, is of inverted U-section with diverging side walls 2A and is mounted by longitudinal extending hinges 14 on runners 12A, 13A slidable in channels 12, 13. In the closed position the lower edges of the side walls 2A abut or overlap the edges 4A of the fuselage, see Fig. 5, and the hinges 14 form a draught seal. Also the front and rear edges 10, 11 of the door abut the edges of the windscreen 1 and fixed portion 3, a rubber sealing member 17, Fig. 6, being provided at the rear edge. To open the door rack and pinion mechanism 19, Fig. 7, is operated to tension Bowden cables 20, 21 connected to cranks 22 mounted at both sides of the windscreen 1. The cranks carry pins 23, accommodated in recesses in the walls 2A and windscreen 1, which on movement of the cranks engage the walls 2A and urge them inwards. Similar mechanism may be provided at the rear edges of the door. As the walls 2a are moved inwards the door is simultaneously dropped due to the action of the hinges 14 until it reaches the position shown in Fig. 4, in which position it may be slidden into the part 3. The hinges 14 pass a dead centre position during deformation and dropping of the door. so the latter is retained in its dropped position In a modification, Fig. 8 (not shown) inclined double pivot hinges are employed instead of the hinges 14 so that the door is moved backward simultaneously as it is deformed and dropped. In this case flexible flanges are provided to seal the gap between the side edges of the door and the fuselage. Aerodynamic means may be employed to urge the walls 2A inwardly or outwardly to open or close the door, e.g. flaps or vanes, controlled from within the cabin and mounted at the rear edge of the windscreen, may be provided to direct the airstream or louvres may be provided in the cabin top to adjust the relation between the internal and external pressures acting on the surfaces of the door.

Abstract: 1,262,668. Supply circuits for discharge lamps. GENERAL ELECTRIC and ENGLISH ELECTRIC COMPANIES Ltd. 1 May, 1970 [11 March, 1969], No. 12715/69. Heading H2H. A circuit for operating a discharge lamp 5 from an A.C. supply comprises a reactive ballast 7 in series with a variable impedance network 8, the network having a relatively high impedance during a small fraction of each period for which current is supplied to the lamp. The network 8, which is similar to that described in Specification 1,262,667, switches to its high impedance state when the lamp starts to conduct during each half cycle thereby attenuating the high lamp current spikes which would otherwise occur. Initiation of the conduction of the lamp is assisted by applying to the lamp the sum of the supply voltage and the voltage of the capacitor 7 charged via a diode 16 and a resistor 17. In a modification the capacitor is replaced by a saturable choke and the components 16, 17 are replaced by a glow discharge starter switch. A circuit including a voltage doubling rectifiercapacitor bridge is also described and may be modified to operate a sodium or mercury vapour lamp.

Abstract: 290,610. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen). May 17, 1927, [Convention date]. Filaments, supports for.-In mounting spiral filaments on support wires a filament is inserted in a jig and a lamp pedestal is positioned with respect to the jig, and the filament is then moved longitudinally to thread it through the eyes of the support wires. The jig shown in Figs. 1 and 2 comprises a straight section 2 and an arcuate section 3 having radial notches 8 into which the ends of the support wires 9 projecting from the lamp mount 10 are inserted, with their eyes in line with a groove 7. A filament is passed down the sloping top 4 of the jig section 2 into a straight groove 5, and this is covered by lowering a block 6 on to the surface 4. The filament is then moved longitudinally from the groove 5 by means of a rod 22 and passes through the groove 7 and is thus threaded into the eyes of the support wires. During this operation the groove 7 is covered by a plate 14 carried by a pivoted arm 13, the cover being slotted at 15 to allow the wires to bepassed vertically into the notches 8. The ends of the filament are attached to the hooks 18 of the leading-in wires by pinching-jaws 20. In the modification shown in Fig. 6, the filaments are threaded into the eyes by compressed air, which is supplied to a channel 24 parallel with the grooves 5, 7 and is directed into these by inclined passages 28. A rotating disc valve 29 having a number of ports 30 admits the air in short puffs. A modification is described wherein the filaments are drawn by suction into the eyes of the wires. The apparatus may occupy one of the stations around a. rotating hook-inserting machine, the next station to it being occupied by an annular clamp which pinches all the eyes more tightly around the filaments.

Filed: 1934-04-27
Abstract: 414,332. Glass manufacture. PILKINGTON BROS., Ltd., 703, Tower Building, Water Street, Liverpool. April 27, 1934, No. 12839. Convention date, May 15, 1933. [Class 56.] In a machine for pressing glassware, the plunger, immediately it has pressed the glass in the mould, is withdrawn slightly from the article so formed and is allowed to remain stationary for a short time, while the glass solidifies, before being withdrawn completely. The first withdrawal prevents the glass from sticking to the plunger, while the plunger remains sufficiently close to the glass to prevent deformation of the article. In the construction shown, the frame 2 of the machine comprises a mould table 3 and plunger guides 4, and it is rotated about a vertical shaft 1. A casing 6, secured to the upper end of the shaft 1, contains cams 7, 9. Bellcrank levers 19 are pivoted on the frame 2, and one arm of each lever engages the cams, while the other raises and lowers a plunger 11. The cam 9 can be adjusted relatively to the cam 7 in order to enable the period during which the plungers are held in the slightly withdrawn position to be adjusted to suit the kind of ware which is being made.

J. ; 1282, Franklin Avenue, Wilkinsburg, Pennsylvania, U.S.A.) April 30, 1935, No. 12856. Convention date, May 26, 1934. [Class 38 (v)] Contacts.-In an outdoor disconnecting switch for medium and high voltage transmission systems, comprising a pair of spaced insulator columns 3, 5 and blade means for bridging conducting means mounted on each of said columns, the blade means and conducting means co-operate to interconnect the insulator columns rigidly, so as to prevent relative movement therebetween, during at least a portion of the circuit closing operation. In the construction shown, the blade means comprise a pair of copper rods 11, 13 linked together at one end by a pair of links 15 and at the other end by a single link 17. The rod 11 is carried by a member 75 pivoted at 77 to the insulator 5 ; and at its other end carries a toothed contact member 93 which, during the closing movement, engages a toothed contact 37 on a U-shaped contact jaw 35 secured to the insulator 3. The contact portion 37 of the other side of the jaw is rounded, to permit a wiping engagement with the contact member 95 carried by the rod 13, the insulators 3, 5 being rigidly interconnected by the toothed members during this wiping movement. The switch is operated by rotating a third insulator 19, which is connected by a crank 49 and link 71, through universal joints 97, 99, to the pivot 91 connecting the link 17 and rod 13. A flat leaf spring 103 is provided between the carrier 75 for the rod 11 and the link 17, and biasses the blade assemblage to the position in which the contact members 93, 95 can move into or out of the contact jaw 35. In the closed position of the switch, the contact members are spread apart by the links 15 and are effectively locked in the contact jaw, and the operating mechanism is slightly overset ; further movement of the rotatable insulator in the closing direction being prevented by stops. To open the switch, the insulator 19 is rotated in the opposite direction, the first effect of the rotation being to cause a longitudinal movement of the rod 13 relatively to the rod 11, with the result that the contact members 93, 95 are moved towards each other by the links 15 and disengaged from the contact jaw 35.

Abstract: 1387307 Colour television RCA CORPORATION 21 March 1972 [29 March 1971] 13077/72 Heading H4F A colour television signal having sub-carrier reference bursts 14 at - (B - Y) phase in each horizontal blanking period has a reference signal 12 at - (B - Y) (or - (R - Y)) phase and subcarrier frequency added during one line period in every (or every second) vertical blanking period. In the recevier, Fig. 2, the bursts 14 are used to lock the frequency and phase of the local oscillator in 50, the reference signal 12 being used to correct the phase of the resulting signal at 54 if the reference signal 12 and the oscillator output are found to be not in phase due to phase errors in the bursts. The reference signal 12 is gated by an amplifier 56 receiving a gating signal from a vertical sync. signal delayed to coincide with reference signal 12, which is then fed to a phase comparator 58 also receiving on input from 54. Any error signal produced controls phase shifter 54 via a circuit 66, 68 with a long time constant. In an alternative embodiment (Fig. 3, not shown) the signal to be fed to circuit 66, 68 is produced by connecting the output of the R - Y demodulator (which should be zero during reference signal 12 of - (B - Y) phase) to amplifier 56. Automatic chroma control may be provided by using a signal dependent on the amplitudes of the bursts, this signal being modified by the output of amplitude comparator 72 receiving inputs of the bursts 14 from 50 and the reference signal 12 from 56.
