Title: Improvements in and relating to apparatus for testing electric lamp bulbs and similar articles for leaks
IPC: B65D25/28
Filed: 1935-12-12
Abstract: 457,954. Testing electric lamp bulbs for leaks. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Dec. 12, 1935, No. 34516. Convention date, Dec. 12, 1934. [Class 106 (ii)] Apparatus for testing electric bulbs &c. for leaks before they have been exhausted and sealed off comprises a chuck for supporting a bulb by the neck in an air-tight manner, and a passage-way connecting the inside of the bulb with a diaphragm chamber compressed air being admitted to the other side of these diaphragms to force the latter back and compress air into the bulb, means controlled by this bulb pressure being adapted to make an electric circuit and discharge a leaky bulb. A turret 10 rotatable about a vertical axis carries a plurality of chucks 11 into which the lamps 13 are inserted. Each lamp comprises a bulb 13 into which a filament and other structure are sealed and to which is sealed an exhaust tube 14. The tubes 14 of the lamps are inserted in the chucks at the position X. The shaft 21 is now rotated and a post 19 on an arm 20 of the shaft engages a pin 22 on the screwed collar 24 thus rotating the sleeve 25 and causing the washer 16 to bulge and grip the tube. The shaft 21 is moved up and down through link-and-lever mechanism from a cam 38. Upon the chuck closing, the mechanism is dropped and the turret advanced one position. The turret is -fast with a tube 53 rotated through a chain 55 by mechanism not shown. In this position, compressed air is supplied through passages 67, 69 to a chamber 58 forcing down the diaphragm 57 into the chamber 73 so that air is forced into the bulb and also into the passage 76 and into a passage (not shown) connected to a Bourdon pressure tube operating a switch. The screw 77 can be adjusted to change the volume of the passages and hence the pressure. The Bourdon tube when moved keeps contact 86 away from a stationary contact 93. The air pressure is maintained until the head 11 arrives at the position Y when the port 68 is closed. If the lamp is leaky, the switch causes contacts 86, 93 to engage. These are connected to contacts 98, 99 on the turret 10 which during indexing of the machine contact with fixed contacts 101, 102 in the circuit of a solenoid 104 which when energized moves a stop rod 108 into the path of unloading mechanism 97. The stop rod prevents the unloading mechanism from its normal swing under the turret when a lamp passing the test is in its head. If the lamp passes it is carried on to unloading mechanism 97 at Y and jaws grip the lamp which is released by a rotation of the collar 25 by a post 109 engaging the pin 22. The shaft 110 carrying the part 109 is rotated through gears 113.. 114 from a shaft 115. An arm 116 on the shaft 110 is connected by a link 37 to a collar 36 so that the chuck closing mechanism at X is operated simultaneously with the chuck release at Y. The unloading mechanism 97 draws a good lamp from the turret and inserts it into an exhaust machine by mechanism not shown.

Title: Metallized azomethine dyes and nylon dyed therewith
IPC: C09B55/00
Filed: 1946-11-21
Abstract: Nylon is dyed using hot aqueous solutions of azomethine dyes containing cobalt in complex combination, which are free from sulphonic groups and have the formula <FORM:0629473/IV (c)/1> where R is a benzene radical having at least one nitro group, and R1 is a benzene or naphthalene radical which may be unsubstituted or may contain monovalent substituents such as nitro, halogen, amino, alkyl, alkoxy, hydroxy, or cyano.  These dyestuffs are obtained by condensing an aromatic ortho-hydroxy amino compound of the benzene or naphthalene series with an ortho-hydroxy benzaldehyde substituted in the nucleus by one or more nitro groups, and heating the resulting azomethine dye, preferably after separation from the reaction mixture, with a solution of a salt of bivalent cobalt.  Solvents for this reaction are water, alcohols, acetone, or esters.  The cobalt compound may be added with the orthohydroxy-amino compound. Reactants specified are 2-aminophenol, 4-chloro-2-aminophenol, 2 - amino - 4.6 - dichlorophenol, 4 - or 5 - nitro-2 - aminophenol, 3 - amino - p - cresol, 4-aminoresorcin - 1 - methylether, 2 - aminoresorcinol, 6 - amino - 2 - cyanphenol, 2 - amino-1 - naphthol, and 2 - amino - 1.4 - dihydroxynaphthalene.  The dyeing solutions may be acid or neutral and may contain surface-active agents and assistants such as ammonium chloride or sodium sulphate.  In examples: 5-nitrosalicylaldehyde is reacted with (1) 2-aminophenol; (2) 4-chloro-2-aminophenol; (3) 4 - nitro - 2 - aminophenol; (4) 2 - amino-4.6 - dichlorophenol and the product is treated with ammonia and cobaltous chloride.

Title: Improvements in or relating to polyamide esters and methods of manufacturing same
IPC: C08G73/14
Filed: 1964-11-18
Abstract: A polyamide-ester is prepared by reacting in solution (a) a tricarboxylic acid monoester diacid halide wherein all 3 carbonyl groups are attached to different carbon atoms, one of the acid halide groups being attached to a carbon atom adjacent to that to which the ester group is attached, with (b) a diamine having at least 2 carbon atoms.  Tricarboxylic acid monoester dihalides specified include the methyl and benzyl esters of trimellitic acid dichloride. Diamines specified include benzidine, bis-(aminophenyl) ether and bis-(aminophenyl) methane.  The reactants may be heated in equimolar amounts, in a solvent at up to 50 DEG  C. The reactants and solvent may be mixed in any order but if the solvent is first added to the acid tricarboxylic acid monoester dihalide an adduct may be formed. This can be avoided by dissolving the diamine and acid derivative in different solvents, e.g. the former in a basic solvent, such as dimethyl formamide or dimethyl acetamide and the latter in a neutral solvent, e.g. benzene.  A base, e.g. NEt3 or pyridine may be present to remove eliminated HCl.  The product may be used as an insulating varnish or as an adhesive or coating for glass fibres or metal.  When heated, it is converted to the corresponding polyamide-imide.ALSO:A mixture of 2 -benzyloxycarbonyl - terephthalic and 4-benzyloxycarbonyl isophthalic acids is prepared by heating trimellitic acid with benzyl alcohol in the presence of water. The product is then reacted with SO2Cl2 to convert the remaining carboxylic acid groups to acid chloride groups.ALSO:A polyamide-ester resin, suitable for coating glass fabric, and Al and Cu foil may be prepared by reacting a tricarboxylic acid mono-ester diacid halide in which an acid halide group is attached to the carbon atom adjacent to the carbon atom to which the ester group is attached and the 3 carbonyl groups are attached to different carbon atoms with a diamine having at least 2 carbon atoms in a solvent.  In Example 2 a reaction product of 4,4\sv-diamino-diphenyl ether and 4-methoxy-carbonyl isophthalyl chloride is dissolved in DMF, applied to Al and Cu foil and baked.

Title: Method and Articles for Splicing Plastic Pipe.
IPC: B29C69/00
Filed: 1967-07-28
Abstract: 1,199,447. Splicing plastic pipes. CENTRAL NATIONAL BANK OF CLEVELAND, and J. D. DRINKO. 28 July, 1967, No. 34712/67. Headings F2G and F2P. A splice member for joining elongated articles, particularly plastic pipes, is made by arranging a plurality of helical reinforcing elements, which have a pitch of the order of more than twice the diameter of the helix, on a mandrel or in a mould, embedding them in plastic material, helically slitting pipe lengths to form a plurality, e.g. a pair, of strips of arcuate section, and cutting the resulting pipe, which has an inner diameter about equal to the outer diameter of the articles to be joined, into convenient splicing lengths which can afterwards be wrapped around the abutting ends of the articles and secured, e.g. by adhesive. In the embodiment shown, the helical reinforcing elements 21, which are rods of either metal, e.g. aluminium, or a "rigid" polyvinyl chloride, are wrapped continuously around a helically wrapped strip forming a core 13, the assembly being then coated, e.g. by a spray nozzle 41, with more flexible plastic material 42. After setting of the plastic, the pipe thus formed is diametrically slit helically along a line parallel to and lying between two adjacent elements 21, before being finally cut into convenient lengths for splicing. Each pair of splice members thus formed is used to form a splice by wrapping the splice members around the abutting ends of, e.g., a pair of pipes 71, 72, and uniting them to each other along the lines G, H and to the tubes at F, I by cementing, bonding or flame welding. In a modification (Fig. 8, not shown) the helical rod elements (21) are held by clamps (91) in position around individual cores (92) of splice length within individual moulds (93) which are filled with plastic material, the resulting tubular splice members being afterwards split helically to form pairs of splice members as in Fig. 7. Fig. 10 (not shown) discloses a pair of splice members each made as a strip of plastic material (111) reinforced and formed into a helix by helical rod elements (21) embedded in it.

Title: Improvements in or relating to the manufacture of glass ribbon
IPC: C03B18/04
Filed: 1963-09-04
Abstract: <PICT:0989413/C1/1> In the manufacture of glass ribbon, the formed ribbon is deposited and slid over a first bath of molten material unaffected by air at the operating temperatures and then transported over at least one other bath of molten material more easily meltable than the first material, the glass becoming progressively solidified as it moves forward over the other bath.  A glass ribbon 1 formed between rollers 2, 3 is deposited on a bath 12, of silver, gold or an alloy of these metals, contained in a furnace 5 and is passed to a second furnace 18 containing a bath 25 of molten tin or lead which is maintained by heaters 26, 27 at a temperature so that the glass ribbon 1 is substantially solidified when it is removed from the furnace 18 on rollers 30 in an annealing lake 31.  Connecting the two furnaces 5, 18, as shown, is a plate 33 of carbon bearing against the lower lips of the furnace openings 17, 28, the upper surface 34 being arcuate with edges 35, 36 below the respective baths 12, 25 so that the glass ribbon 1 slides over the carbon plate 33.  The plate 33 is protected by a crown 37 and lower plate 38 and a reducing gas may be passed through the chamber 48 so formed to prevent oxidation.  In a second embodiment, not shown, the plate 33 is replaced by a block, the sides of which form the lower end walls of the furnaces 5, 18. To improve the fire polish, the first bath 12 may be heated to such temperature as to heat the glass ribbon, there being no risk of oxidation of the metal to give metal oxide contamination of the glass.

Title: Improvements in or relating to light-sensitive devices and the utilisation of light-energy to control other forms of energy
IPC: H03B17/00
Filed: 1928-12-01
Abstract: 326,498. Robinson, J. Dec. 1, 1928. Telegraphic transmitters. - A modulated light-b e a m causes variations of electric energy by incidence on a piezo-electric crystal. The invention is applicable to telegraphy and to reproduction from sound films. In the arrangement shown in Fig. 1 the light from a neon lamp 10 is subjected to pulsating voltage from the source 11 and consequently exerts a fluctuating mechanical pressure on the surface 16 of the piezo-electric crystal 14 which resonates and so energizes a tuned circuit 13. The surface 16 may be black, reflecting, or photo-electric. In modifications the light may fall upon a fixed photoelectric surface, the electrons from which impinge upon a metallic surface on the face of the crystal (Fig. 2, not shown). Part of the energy from the resonant system 13 may be fed back to the lamp 10 (Fig. 3, not shown, and Fig. 5) or to a Kerr cell placed in the path of the fluctuating light beam (Fig. 4, not shown). The length of the light-path may be varied by adjustment of two mirrors 27, 28, and in this way the relative phases of the input and output oscillations of the system may be controlled. An object such as a sound film record may be interposed in the path of the light and modify the intensity of the latter by reflection or transmission.

Title: Method and apparatus for supporting a sheet of heat softenable material, such as glass
IPC: C03B35/18
Filed: 1962-09-19
Abstract: Sheets of heat-softenable material such as glass, heated to deformation temperature, are partially supported while being transported on rolling supports by means of upwardly flowing fluids between the rolling supports.  The sheet is fed on rollers 34 between which are elements 103 of refractory material forming open-ended compartments 106 round the individual rollers and passages 102 between the rollers.  The elements rest on the top of a chamber 50 to which fluids such as air and hot combustion <PICT:1021844/C1/1> gases are supplied under pressure, apertures in the top of the chamber registering with the passages 102.  The fluid under pressure therefore escapes through the passages 102 and helps to support the sheet, subsequently passing into the compartments 106. The sheet is heated to the required temperature by the gas and by electric heating elements in the roof of the section and is subsequently fed to a quenching section and finally discharged. In a modification, elements 103 are dispensed with and the top of the chamber is formed by a number of rollers arranged close together.  The support may be tilted instead of horizontal.
