Title: Manufacture of dyestuffs of the triarylmethane series
IPC: C09B11/24
Filed: 1936-08-18
Abstract: Dyestuffs of the triarylmethane series are prepared by condensing one molecular proportion 3- or 5-hydroxytrimellitic anhydride or molecular proportion of an N-substituted meta aminophenol, and further condensing the resulting N-substituted 2 - (41 - amino - 21 - hydroxy) benzoylcarboxyhydroxy-1-benzoic acid with a compound having the formula <FORM:0480328/IV/1> in which X is a reactive hydrogen atom and R is aryl.  The dyestuffs dye animal fibres orange or blue tints and may be used for chrome printing on cotton and artificial silk other than acetate artificial silk.  The dyestuffs may be chromed on the fibre or in substance.  To facilitate the condensation, p-toluenesulphonic acid, methylsulphuric acid or sulphuric acid may be used; in the latter case, sulphonation is effected.  In examples: (1) the diethylaminodihydroxycarboxy-o-benzoylbenzoic acid, obtained from diethylamino-m-phenol and 5-hydroxytrimellitic anhydride is condensed with azo dyestuffs prepared as follows from (a) resorcinol and diazotized 1-amino-2-hydroxynaphthalene-4-sulphonic acid, (b) resorcinol and diazotized 1-amino-2-naphthol, (c) resorcinol and diazotized 5-sulpho-3-aminosalicylic acid, (d) resorcinol and diazotized p-aminosalicylic acid, (e) resorcinol and diazotized o-aminophenol, (f) resorcinol and diazotized o-anisidine, (g) resorcinol and diazotized 1-amino-2-naphthol and (h) resorcinol and diazotized 1-amino-2-hydroxy-3-naphthoic acid; (2) the dimethylaminodihydroxy carboxybenzoylbenzoic acid, obtained from 5-hydroxytrimellitic anhydride and m-dimethylaminophenol is condensed with azo dyestuffs prepared from diazotized 1-amino-2-naphthol and resorcinol and from diazotized p-amino salicylic acid and resorcinol.

Title: Improvements in or relating to tyre vulcanising presses
IPC: B29D30/06
Filed: 1967-05-17
Abstract: 1,131,174. Moulding tyres. M. GUHR and A HERBERT [trading as LEONH. HERBERT MASCHINENFABRIK]. 17 May, 1967 [17 May, 1966], No. 22857/67. Heading B5A. A tyre vulcanizing press, e.g. for retreaded tyres includes separable mould halves 2, 4 and a heating bag 23 attached at its lower end to a piston 25 slidable in a cylinder 28 and at its upper end to a plate 24 carried by a tube 32 coaxial with an outer tube 38 supporting the piston. Depending on the cross-section of the tyre 21, the piston 25 is raised to a greater or lesser extent to insert the bag into the tyre cavity, and accordingly a drive is provided to raise the piston to any one of a number of predetermined positions. The drive includes an electric motor which, by a chain 48 rotates a nut 41 mounted in bearings on a fixed support 45; the nut engages threads on the piston support tube 38 which is prevented from rotating by a screw 58 engaging a groove 56 in the tube. The motor drives, through a gear, a camshaft which rotates less than one revolution during the maximum displacement of the piston, and the cam, during its rotation contacts a number of circumferentially spaced series connected switches located in the motor supply circuit and connected to a set of manually operated switches. The operation of each of the latter effects a predetermined displacement of the piston since, as the cam rotates it operates the appropriate one of the circumferentially spaced switches to interrupt the motor circuit. A vulcanizing agent e.g. hot water, is fed into the bag via a pipe 55, the space between tubes 36 and 51, and bores 54; the bag is simultaneously vented via passages 34a, 34, pipe 51 and outlet 52. After a predetermined period the hot water is drawn off through the pipe 55, and the bag is retracted by the operation of a switch by a timing relay which drives the motor in the opposite direction. By the operation of a further switch the piston is raised to a high position for bag replacement purposes.

Title: Installation tool for flush mounted inserts
IPC: B25B15/02
Filed: 1974-05-22
Abstract: 1454571 Installation tools AMERACE CORP 22 May 1974 [22 May 1973] 22905/74 Heading B3N An installation tool 10 is for inserting a panel insert 12 into a panel 14 until the top face 34 thereof is flush with surface 32 of the panel. The tool has a drive shaft 36 with a head 46, the shaft is rotated by hand wheel 38. In the head a bushing 60 carries drive pins 48 and a locater pin 52 that engage in insert 14. A locating pad 58 is fixed to the bushing and has a locating surface 62 complementary to face 34 of the insert. A magnet 64 retains an insert on the pins. A sensing member 70 is rotatably and axially movably mounted on the drive shaft and has a sensing surface 72 radially aligned with surface 62. A collar 80 is axially located and rotatably mounted on the drive shaft. A clutch ring 88 rotates with the drive shaft and is spring biased against collar 80 so that when member 70 is moved forward, friction between the engaging surfaces on the collar and clutch ring force the collar to rotate with the drive shaft. In operation an insert is engaged with pins 48 and member 70 manually moved forward to engage surface 32. Since surface 72 is perpendicular to axis N this ensures the insert is correctly aligned. As the insert is rotated into cavity 24 member 70 moves upwardly until it engages collar 80. The engaging surfaces of the collar and member 70 are at a greater radius than for the engaging surfaces between the collar and the clutch ring. Therefore they exert a greater torque on the collar and stop rotation thereof. This is the indication that the insert is a flush fit in the panel.

Filed: 1955-08-10
Abstract: 798,589. Making waveguide couplings ; flanging. DECCA RECORD CO., Ltd. Sept. 12, 1956 [Aug. 10, 1955], No. 23109/55. Classes 83 (2) and 83 (4). [Also in Group XL (b)] A waveguide choking coupling is formed by soldering a flange member 12 on to a waveguide 10 and then forming steps on the flange so that part of its axial length fits into a hole in a wall 11, which, with the bottom step, forms the choke. The flange member 12 is silver soldered to the waveguide, the end of which is flush with the outer face of the member 12. The waveguide is then supported on a mandrel while the member 12 is turned down on a lathe to provide three steps of circular cross-section. The centre step is then lightly fitted and silver soldered into a hole in the wall 11 so that a quarter wavelength choke is formed, the inner side wall by the bottom step 13, the base by the shoulder 14, and the outer side wall by the inner face of the hole 16. The axial length of the first and second steps is such that the waveguide does not reach the outer face of the wall.

Filed: 1928-08-15
Abstract: 304,748. Siemens - Schuckertwerke Akt.-Ges. Jan. 27, 1928, [Convention date]. Contacting-solid resistances.-An electrode for a dry surface contact rectifier is formed by placing layers of copper sulphide powder and pulverized copper in a mould and subjecting the whole to high pressure of the order of several thousand kilogrammes per square centimetre. The copper layers are preferably twice as thick as the sulphide layers and the electrode is made of hollow cylindrical shape. The counter electrode is made of aluminium or magnesium and is brought into operative contact with the first electrode with a pressure less than one tenth of the pressure used in forming the first electrode. The dimensions of the electrodes are made sufficiently small to enable good contact to be obtained between them over the whole of the designed contact area. Selenium or tellurium compounds of a metal may be used in place of the sulphide. The latter, when used, is obtained in a dry state by mixing sulphur powder with commercial copper sulphide powder and sublimating the excess of sulphur by heating to a temperature of 250‹ C.
