Title: Metallized ortho-hydroxy, ortho-amino monoazo dyestuffs
Filed: 1948-11-16
Abstract: N-Mono-(carboxyalkyl)-diamines of the general formula <FORM:0656698/IV (b)/1> (wherein R represents a carboxymethyl, 1-carboxyethyl or 1-carboxyisopropyl radical and Y represents hydrogen or an alkyl or alkoxy radical) are manufactured by reduction of the corresponding nitro compounds, e.g. m-nitrophenylglycine, 5 - nitro - 2 - methylphenylglycine or the alkyl- and alkoxy-m-amino-anilido-acetic, -propionic and -butyric acids obtained by condensing alkyl- and alkoxy-m-nitranilines with chloracetic, a -chloropropionic and a -chloroisobutyric acid respectively.ALSO:Metallized azo dyestuffs of the general formula <FORM:0656698/IV (c)/1> (wherein one R represents hydrogen and the other a carboxymethyl, 1-carboxyethyl or 1-carboxyisopropyl radical, X represents hydrogen, halogen or an alkyl, alkoxy or nitro radical, Y represents hydrogen or an alkyl or alkoxy radical, and ME represents chromium, copper, cobalt or nickel in complex combination) are manufactured by diazotizing an unsulphonated o-aminophenol which may be substituted by halogen (e.g. chlorine), a nitro group or an alkyl (e.g. methyl or ethyl) or alkoxy (e.g. methoxy or ethoxy) radical, coupling (in neutral or weakly acid medium) with a diamine of the general formula <FORM:0656698/IV (c)/2> (wherein R represents one of the aforesaid carboxyalkyl radicals), and metallizing the product.  The metallized dyestuffs dye nylon from aqueous solution (being sufficiently water-soluble to make dispersion unnecessary), and may be used alone or in admixture with known dyestuffs for nylon. The dyebath may be neutral or preferably slightly acid, e.g. acidified with acetic or formic acid or with substances which liberate acid on heating, such as ammonium thiocyanate or diethyl tartrate.  In an example, the dyestuff 4-nitro-2-aminophenol --> 3-aminophenylglycine (which is probably a mixture of the N2- and N4-carboxymethyl compounds) is heated with an aqueous solution of nickeloussulphate, coppersulphate, cobaltous chloride or chromium formate.  Lists of additional diazo and coupling components are given.

Title: Methods and machines for fabricating sheet-metal panel structures
IPC: B23Q7/14
Filed: 1959-09-03
Abstract: 928,228. Making vehicle panel structures; seaming; welding by pressure. BRITISH FEDERAL WELDER & MACHINE CO. Ltd., and T. F. TRIBE. Sept. 3, 1959, No. 30118/59. Classes 83 (2) and 83 (4). In a machine for fabricating panel structures, e.g. vehicle doors, lids and floor assemblies, in which operations are simultaneously performed on a number of workpieces at a number of spaced stations, the workpieces are transferred from station to station by a reciprocating frame, clamps are provided to secure them on the frame and holding devices at each station hold them during the fabricating operations, the clamps and holding devices being actuated to each secure a workpiece before the other releases. A door assembly 11 is located manually on a pad 19 on the frame 14 and is secured by clamps 20. Spot welding tools 32 carried by a ram 40 tack-weld the panels of the assembly. After the frame 14 has been moved forward by a ram 18, the assembly 11 is gripped by holding devices 27, 31 which after the clamps 20 have been released lifts it to be resistance welded by the electrodes 29. Meanwhile, the frame 14 is returned and another assembly 11 is placed upon it. The welded assembly 11 is lowered, secured to the frame 14 by clamps 20 and released by the holding devices 27, 31. At subsequent stations the edges of the assembly are clinched over by pneumatic tools 30 and resistance welded by further electrodes 29. The assembly is removed from the machine down a conveyer 36. Instead of being raised at each work-station the assemblies may be lowered and/or the tools may be moved vertically. At the welding stations a single electrode may be indexed to make the necessary welds. All movements are pneumatically actuated and may be automatically controlled. A number of such machines 50, Fig. 9, may be arranged in parallel to produce sub-assemblies 51 which are fed into the work-stations of a similar machine 52 transversely located to assemble the subassemblies. Specifications 925,167 and 928,229 are referred to.

Title: Dictation apparatus
IPC: G11B25/06
Filed: 1960-09-01
Abstract: 952,634. Dictating machines. DICTAPHONE CORPORATION. Sept. 1, 1960 [Sept. 25, 1959], No. 30159/60. Heading G5R. An improvement of the belt-record/embossing- stylus record/playback apparatus of the type described in Specifications 910,739, 910,740, which are considerably referred to, separate carriages, 34, 36 for the record and playback heads are selectively engageable with a single leadscrew 44 which permits back-spacing of the playback head while allowing the record head to wait at its previous recording position. The leadscrew may be reversed at high speed to backspace the carriage 36, the carriage 34 being held by a sprag 150. Rachets,82, 108, secured to worm-wheels (Fig. 9, not shown) are engaged by solenoid-actuated detents 80, 106 when the carriages are to be driven, and cam means 120 rotated by a half-turn of the centre guide-rod 40 move the heads out of contact with the record during back-spacing. During recording, the carriage 36 normally follows the carriage 34 by the action of a negator spring 114, coupling them; on the resumption of recording, this spring, overcome during the back-spacing operation, returns the carriage 36 to its position close behind the carriage 34. An incremental advance of the carriage 34 when the carriage 36 is backspaced prevents possible double recording due to backlash. In a further embodiment, (Figs. 13, 14, not shown) power-driven means, similar to the earlier machines, return both carriages to their start position and eject the record.
