Title: Improvements in semi-conductor circuits
IPC: H03F1/30
Filed: 1952-01-28
Abstract: 715,970. Semi-conductor amplifier circuits. STALHANE, B. Jan. 28, 1952 [Jan. 31, 1951], No. 2310/52. Class 40 (6) The bias for the emitter 4 in a transistor circuit is obtained from a constantvoltage type of resistance 11 (e.g. a varistor or a thermistor) which is'connected in series with the base electrode 2. The collector 3 is biased by means of battery 5, and the input signal 9 is applied to the emitter 4. Resistance 8 in series with the emitter enables the emitter current to be adjusted to a desired level. A three stage cascade amplifier is described, in which the bias battery is connected across the collectorbase circuits of the three transistors connected in series. A push-pull amplifier circuit is also described. The signal input circuit may be connected in parallel with the biasing circuit comprising resistance 8; and a linear resistance may be connected in series with a thermistor to provide the constant-voltage resistsance 11. The constant-voltage resistance may consist of silicon carbide, selenium or copper oxide dry plate rectifiers, or varistors of the type described in Specification 589,574, [Group XXXVI], which provide a large shunt capacity. Specification 694,025 also is referred to.

IPC: C09B31/28
Filed: 1936-01-27
Abstract: Polyazo dyes are made by coupling a diazo or diazoazo compound with a p-coupling amine, and if the amine is of the naphthalene series, free from hydroxy or substituted hydroxy groups, further diazotizing, coupling with an aminoaroylaminonaphthol mono or disulphonic acid, further diazotizing and coupling with an aminoaryl pyrazolone.  They may be further diazotized and coupled in substance or the fibre or after-treated on the fibre with diazo compounds.  Brown shades of good dischargeability are obtained. In examples, the following dyes are described: (1) m-xylidine-o-sulphonic acid --> cresidine --> N-p-aminobenzoyl J-acid --> 1-m-aminophenyl-5-pyrazolone-3-carboxylic acid or 1-p-aminophenyl-3-methyl-5-pyrazolone; the former when diazotized on the fibre and developed with b -naphthol or m-phenylenediamine or treated on the fibre with diazotized p-nitraniline gives brown shades and the latter when diazotized on the fibre and developed with m-phenylenediamine gives reddish brown shades; (2) Cleves' acid is used instead of cresidine; (3) and (4) p-aminobenzoyl-2 : 8 : 6- or 1 : 5 : 7-acid is used instead of the J-acid derivative; (5) 2-naphthylamine-4 : 8-disulphonic acid --> m-toluidine --> o-toluidine --> N-p-aminobenzoyl J-acid --> 1 - m - aminophenyl - 5 - pyrazolone - 3 - carboxylic acid --> (on the fibre) m-phenylenediamine; (6) N-p-aminobenzoyl H-acid is used instead of the J-acid compound in (5); (7) 2-naphthylamine-4 : 8-disulphonic acid --> p-xylidine --> cresidine --> N-p-aminobenzoyl J-acid --> 1-m-aminophenyl-5-pyrazolone-3-carboxylic acid --> (on the fibre) m-phenylenediamine; (8) 2-naphthylamine-8-sulphonic acid --> cresidine --> N-p-aminobenzoyl J-acid --> 1-m-aminophenylpyrazolone-3-carboxylic acid --> (on the fibre) m-phenylene diamine.

Patent GB-161008-A (GB)
Title: Machine for polishing knives
IPC: B24B19/00
Filed: 1920-01-27
Abstract: 161,008. Siepmann, E. Jan 27, 1920. Disc apparatus.-Knives are polished by means of a wooden or other polishing disc 33 carried by an axially movable spindle 37 which is engaged at its rear end by a spring-pressed centre point 38, polishing-material being supplied to the disc from a container 34 by means of a revolving brush 35. The knife is supported by pins 25, on a resilient backing carried by a holder 22 pivoted on pins 21 on a cross-slide 20 movable to and from the polishing-disc on a slide 11 which is reciprocated, to carry the knife across the face of the disc, by rack-and-pinion gearing driven through gearing 3 - - 6 by two oppositely-driven pulleys 1, 2. Reversal of the motion of the slide 11 is brought about by a slidable clutch 8 moved by a lever 18 pivoted at 18', the lever being thrown over by means of a handle 17, against the action of a spring 46, to start the slide and being moved to throw over the clutch 8, at the end of the inward stroke, by the engagement of a cam 15 on the lever by a roller 13. The roller is carried by a bracket 12 mounted on the slide, and the bracket also carries a pin 14 which, towards the end of the outward stroke of the slide, engages a cam 16 on the lever and rocks this, against the action of the spring 46, to set the clutch 8 in the neutral position; the slide thus makes one to-and-fro movement and then comes to rest. In order to give convexity to the knife blade, the holder 22 has thereon an arm 26 which rides on a bar 27 pivoted to a fork 29 and adjustable, by means of screws 28, to different inclinations; the fork is reciprocated vertically and the knife holder is thus rocked on its pivots. The cross-slide 20 is moved on the slide 11 by the engagement of a pin 43 on the crossslide by the bevelled part of a cam 41 pivoted on the slide 11 and adapted to be rocked by contact with adjustable stops 42, 44; springs 45 normally hold the cross-slide away from the polishing-disc.
