Title: Improvements in the manufacture and production of azo dyestuffs
IPC: C09B29/20
Filed: 1934-09-03
Abstract: Azo dyes are made by coupling aromatic diazo, diazoazo or tetrazo compounds free from sulphonic and carboxylic groups, but which may contain halogen, nitro or other substituents, with aromatic o-hydroxycarboxylic acid amides free from sulphonic and carboxylic acid groups which have no free p-position to the hydroxyl group and which contain attached to the nitrogen atom of the acid amide radicle at least one aliphatic radicle having more than five carbon atoms. They are soluble in hydrocarbons, alcohols, ethers, ketones, paraffin waxes, fats, waxes and oils and may be used for colouring these materials and in the manufacture of coloured nitrocellulose lacquers, films, candles, polishing-waxes, and shoe polishes.  In an example, diazotized aniline is coupled with 2 : 3-oxynaphthoic acid dodecylamide in pyridine or in an aqueous suspension in presence of acetone and turkey red oil.  Dyestuffs from the following components are also specified: p-toluidine, a -naphthylamine, aminoazobenzene, 2-amino-1 : 4-dimethoxybenzene, p-nitraniline, 1-amino-2-nitro-4-methylbenzene, dianisidine, 1-benzoylamino-2 : 5-diethoxy-4-aminobenzene, 1-amino-2-methoxydiphenylamine and 4 : 4<1> - diaminodiphenylamine; 1 - methyl - 4 - hydroxybenzene - 3-carboxylic acid decylamide, 2 : 3-oxynapthoic acid methyldodecylamide, 2 : 3-oxyanthracene carboxylic acid dodecylamide, 6-methoxy-2-naphthol-3-carboxylic acid oleylamide. o-Hydroxycarboxylic amides of the above kind are obtainable by condensing the acid, e.g. p-cresotinic acid, 2 : 3-oxynaphthoic acid, 2 : 3-oxyanthracene or 2 : 3-oxycarbazole carboxylic acids with primary or secondary amines having at least one aliphatic radicle containing more than five carbon atoms, such as hexylamine, dodecylamine, octodecylamine, oleylamine, methyldodecylamine, di-doceylamine, cyclohexyldodecylamine and hexylaniline or mixtures thereof.  Such amines may be prepared according to Specification 421,718.  The Specification as open to inspection under Sect. 91 comprises an example in which tetrazo dianisidine is coupled with 2 : 3-oxynaphthoic acid dodecylamide and b -naphthol in a mixture of pyridine and methanol.  Other additional components specified are ethyl-b -napththylamine, p - cresol, p - cyclohexylphenol, 2 : 4-hydroxyquinoline, methylphenylpyrazolone and acetic acid anilide. This subject-matter does not appear in the Specification as accepted.

In the inking system of a rotary press a transfer roller 11, Fig. 1, which extends across the whole width of the press, comprises a series of parts 11A, 11B &c., Fig. 4, which parts may be selectively operated such that either all the parts collect ink from a ductor roller 2, which also extends across the press and is in association with a main ink duct 1, or, at least one part (but not all) collects ink from the ductor roller 2 whilst each of the remaining parts collects ink from an auxiliary ink ductor roller 4, a series of which are arranged end-to-end across the press and are fed from individual ink ducts 3. In a third position of the transfer roller parts no ink is transferred at all. The transfer roller shown is divided into four parts which are arranged in pairs, each of which is controlled from one side of the press. The parts of each pair are eccentrically mounted relative to a fixed axis 9 such that rotational actuation of lever mechanism, such as 19A and 19B in the case of parts 11A and 11B, will move the selected roller part into and out of contact with the rollers 2, 3 and 7 as desired. Each roller part mounts a pinion wheel 18 by which it is rotated by the forme cylinder. In a further embodiment, the roller parts are eccentrically mounted on a fixed axle bar, the rotational drive for each pair of parts being transmitted individually to the parts at the respective side of the press. In yet another embodiment, each roller pair is coupled such that a single drive at the press side will suffice to rotate the parts.

Title: Method of decorating and decorated articles
Inventor: HANDS HORACE GEOFFREY
IPC: B44C1/22
Filed: 1965-06-18
Abstract: A method of decorating a surface comprises forming a resist layer on portions of the surface to be uncoated, applying a coating to the surface including those portions having the resist layer thereon contacting the coating with an adhesive which adheres to the coating, and removing the adhesive thereby removing the portions of the coating over the resist layer.  The resist layer may be a wax type coating such as a polyethylene or polytetrafluorethylene wax or mixtures thereof supported by a carrier and the layer may be formed by hot stamping the carrier against the surface.  Coatings mentioned are paints, metals.  One or more coatings may be sprayed over the surface and/or the surface may be vacuum metallized.  The adhesive may be a film which becomes tacky and adhesive on heating to its softening point, e.g. a polymeric film softening at 250 DEG  to 300 DEG F. such as an acrylic ester polymer.  The film may be carried on a polyester tape, and intermediate metal such as aluminium coating may be employed between the film and the tape.  In the Example, a translucent plastics part having raised numerals for use as an automobile speedometer dial is contacted with a polyester tape coated with a composition comprising 40% polyethylene wax and 60% tetrafluorethylene polymer wax which is transferred to the raised surfaces by hot pressing.  The part is then sprayed with a base paint, vacuum metallized to form an aluminium coating, and a transparent protective coating sprayed on.  An acrylic ester polymer carrying tape is placed against the raised surfaces of the part, heated to render the film adhesive, and pulled away from the part.

Abstract: 952,996. Infra-red detections of hot bearings. WESTINGHOUSE AIR BRAKE CO. July 25,1960 [July 24, 1959], No.25837/60. Heading G1A. [Also in Division B7] Infra-red radiation from railway train wheels having a hot bearing is detected and identified with particular cars by correlating means. Infra-red radiation from a wheel 25, Fig. 1, is reflected by hyperbolic mirrors 15a, 15b through a hole in mirror 15a and a rotating perforated drum 19 to an indium antimonide detector 17. The optical system axis is at 40-60 degrees to the horizontal and perpendicular to the track. Such arrangements 11 are installed on either side of the track, Fig.2. Inductors 31, 33 provide pulses on passage of a wheel to operate the detect gate 45 which opens gates 41a, 41b to connect the output of detectors 17 when a wheel 25 is passing to level detectors 47, 49 which give an output when either bearing is too hot and to a differential amplifier 51 to cause differential detectors 55, 57 to give an output on opening of the compare gate 53 when one bearing is a predetermined amount hotter than the other. Conventional track circuits establish the direction of motion of the train to determine which of inductors 31, 33 provides the open and which the close pulse for gate 45. The outputs of detectors 47, 49, 55, 57 are coded in a known matrix 59 and the 3- bit output thereof transferred on opening of a gate 61 to a storage system comprising storage banks A, B, C, through a gate 63. On completion of the transfer, gate 62 opens to reset the detectors 47, 49, 55, 57. Each time inductors 31, 33 detect a wheel they send a pulse through a gate 45 to a divider 65 which produces one pulse per car. These pulses are counted in binary coded decimal counters 67, 69, 71. Each time gate 63 opens to transmit hot bearing information to the storage system it sends a pulse to open a gate 73 so that the car number is also transferred to the storage system. The information cascades to the lowest empty bank of the storage system (described in Specification 952, 997) and the information inbankA is displayed to an operator on a panel 175, Fig.9 (not shown). If bank B is also full, a signal to this effect is sent over lead 80. Actuation of a reset 174 destroys the information in bank A and that in bank B takes its place for display. If a hot bearing is detected when all the banks are full, gate 78 is opened to store the fact that a hot bearing has been missed and this is transmitted to bank A as soon as all the banks are empty. U.S.A. Specifications 2,698,425, 2,736,016. and 2,754,500 also are referred to.

In an air cooled direc fuel injection engine ir order to prevent fue which may leak from the injection from fouling the cooling fins the in jector is either located downstream of the cylinder with respect to the flow of cooling air or as shown a baffle 8 is pro vided to lead the fuel to the downstream side of the cylinder. In the former case a channel may be provided above the cylinder head in the cooling air jacket 2. or separately to lead a current of air towards the fuel injector for cooling it. A specially shaped drip pan or a short baffle may be provided extending from the cylinder wall rearwardly beneath the valve to ensure that any fuel leaking therefrom falls clear of the fins. The injector is located in the air outlet of the cooling jacket. Thus both the valve and the fuel pipe leading to it can be detached without first removing the jacket. The cylinders may be horizontally or obliquely arranged as well as vertically. The air guiding means may provide a current of air in a different direction from that of the cylinder cooling air. The invention is described as applied to two-stroke cycle engines.
