Title: Manufacture of easily soluble ester-salts of leuco-vat-dyestuffs
IPC: C09B9/00
Filed: 1933-01-24
Abstract: The acid disulphuric ester salts of leuco-vat dyes are converted into their lithium salts which are characterized by an excellent solubility in water.  In general such salts are prepared by treating the acid disulphuric ester of leuco-vat dyes in the form of their salts with a volatile base such as pyridine, piperidine, ammonia, dimethylaniline or aniline, with lithium carbonate or hydroxide and then expelling the volatile base by distillation; thus in preparing an acid disulphuric ester of a leuco-vat dye by treating a suspension of a leuco-vat dye in a tertiary base with an addition product of sulphur trioxide and a tertiary base, lithium carbonate is added and the solution distilled.  Or the preparation may involve double decomposition with formation of an insoluble salt; thus a barium salt of a disulphuric acid ester of a leuco-vat dye may be treated with lithium carbonate or sulphate.  Reference is made to the production of the lithium salts of the disulphuric acid esters of dichloro- and dibromoanthanthrone (cf. Specification 260,998, [Class 2 (iii), Dyes &c.]), dibromodibenzpyrenequinone, pyranthrone and dibromopyranthrone (cf. Specification 320,368, [Class 2 (iii), Dyes &c.]), indanthrene and dichlorindanthrene (cf. Specification 322,277, [Class 2 (iii), Dyes &c.]), dibenzanthrone and isodibenzanthrone and substitution products thereof.  The products are useful for printing purposes. Specifications 186,057, [Class 2 (iii), Dyes &c.], and 363,669 also are referred to.  The Specification as open to inspection under Sect. 91 comprises the production of lithium salts of leuco sulphuric esters of vat dyes generally, but this subject-matter does not appear in the Specification as accepted.

Abstract: 778,539. Multiple writing instruments. WALDMANN, A., [trading as WALDMANN, A. [Firm of]. Jan. 25, 1956, No. 2416/56. Class 146(3). A multiple writing instrument comprises a slotted outer casing 5, a sleeve 2 secured within the casing holding resiliently-loaded rods 17 carrying writing appliances, e.g. ball-point pens 14a, 14b, thrust pins 15a, 15b on the rods 17 guided in slots parallel to the longitudinal axis of the instrument, and a cam-carrying sleeve 6 rotatable by an end cap 9 to move the pens 14a, 14b into and out of writing position and longitudinally displaceable to advance the pen in writing position beyond writing position whilst the retracted pen remains stationary, the cam 16 on the sleeve 6 extending gradually forward from a recess 21 to a notch 20 in which a thrust pin engages when a pen is advanced to writing position, then receding first abruptly and then progressively to the recess, whereby a thrust pin may be released from the notch 20 by rotation of the end cap in either direction. The pens 14a, 14b are pressed rearwardly by springs 18, while the cap 9 is pressed rearwardly by a spring 8. The pen 14a may be disengaged from writing position, as determined by the pin 15a engaging the notch 20, by clockwise or counterclockwise rotation of the cap 9 ; in the former case the same pen may subsequently return to writing position without projecting the pen 14b first, while rotation in the counterclockwise direction causes the pen 14b to be projected next, since the slope 22 of the cam prevents clockwise rotation. Depression of the cap 9, against the spring 8, permits a sufficient advance of the projected pen to permit its removal and replacement. When the appliances are pencils, refill leads may be stored in a spring housing 7.

Rotary machines; cylinder machines; offset machines. - A multi-colour printing press having the printing-members in tandem is constructed so that the sheet may be moved transversely of the press between successive impressions to secure a good lateral register of the impressions. The machine is constructed to include an impression or transfer cylinder, which can be adjusted while the machine is in operation to make part of its rotation and then be shifted laterally to an adjustable extent in either direction, and to be returned to its original position when each rotation is complete. As applied to a two-colour rotary offset press, the printed sheet is transferred from the impression cylinder 10, Fig. 1, which coacts with an offset cylinder 8, to an impression cylinder 11 by means of a transfer cylinder 12 which can be moved transversely of the press after it has taken the sheet from cylinder 10. The movement of cylinder 12 is effected by a stationary cam comprising a fixed segment 16 and a pivoted segment 18, which can be adjusted by a screw and a nut operated by a worm-wheel 25 and worm 26. A fixed pin 32 in a slot 31 in the nut limits the extent of adjustment, and a pointer 34 and a scale indicates the amount of the adjustment. Rollers 21, 22 on a bracket 20 attached to the cylinder 12 embrace the cam, and transfer motion to the cylinder 12. The invention may be applied to direct rotary or cylinder presses, and the cylinder 12 may bear impression cylinder coacting at different periods with different printing-surfaces. Instead of moving the whole cylinder, the grippers only may be moved.

Abstract: 524,225. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., BARNARD, R. M. Jan. 24, 1939, No. 2480. [Class 40 (v)] In a beat-frequency generator for producing a wide band of frequencies, the wide band is divided into a series. of limited ranges related to one another by a constant ratio e.g. 300 cycles-3 Kc., 3 Kc.-30 Kc., 30 Kc.-300 Kc. &c. by the provision of interchangeable tuning circuits which vary the frequency of both oscillators in the same ratio so that the beat frequencies will also vary in the same ratio and the frequency in any of the limited ranges may be read off from a single scale associated with a variable condenser in one of the oscillators which provides tuning within any of the ranges. In the example shown, one oscillator V2 provides a number of fixed frequencies 10 Kc., -100 Kc., 1 Mc., 10 Me., determined by interchangeable crystal elements X (or in the lower range by a tuned circuit L2, C4 only), and the other oscillator V1 has interchangeable tuning elements L1, C3 which with a variable condenser C5 provide frequency ranges of 7 Kc.-9.7 Kc., 70 Kc.-97 Kc., 700 Kc.-970 Kc., 7 Mc.-9.7 Mc. These fundamental frequencies are combined, after amplification, in a valve V5 and the difference frequencies corresponding to ranges of 300 cycles-3 Kc., 3 Kc.-30 Kc., 30 Kc.- 300 Kc., 300 Kc.-3 Mc. are selected by a bandpass filter F which is also interchangeable. The interchangeable units may be of plug-in type. The difference frequency produced may be checked in a cathode-ray oscillograph CRO with a standard frequency or, by changing over a switch S, with one of the frequencies of the crystal-controlled oscillator V2, any required adjustment being made by means of condenser C3.
