Title: Stable diazonium salt preparations and their use for producing water-insoluble azo-dyestuffs on the fibre
Filed: 1962-11-12
Abstract: Water-insoluble azo dyes are formed on the fibre in a process wherein a fibrous material impregnated with a solution of an alkali metal salt of a coupling component is developed with a bath which contains, besides a diazonium compound of a primary aromatic amine and aluminium sulphate, an a -hydroxy-monocarboxylic acid, an a -hydroxypolycarboxylic acid and/or a water-soluble alkali metal salt thereof and, if desired, an alkali metal acetate or bicarbonate.  The specified a -hydroxy-carboxylic acids are citric, tartaric, malic, mandelic, lactic, gluconic and saccharic acid as well as acid or neutral alkali metal salts thereof.  The amount of a -hydroxy-carboxylic acid is chosen to give a pH of 2.5-7.5.  The developing bath may be prepared by diazotising the amine in the normal may and then adding the required amounts of the above-mentioned additives.  Alternatively the diazonium compound may be isolated in a solid stabilized form and a solid dye preparation prepared by adding the additives in solid form. The stabilized diazonium compounds may be diazonium chlorides, sulphates, arylsulphonates, boro-fluorides and double salts of diazonium chlorides with zinc chloride.  A number of suitable diazotisable amines are specified.  Using the present developing baths coupling in the neutral range of pH 6-8 with difficulty coupling components such as the arylamides of 3-hydroxy-diphenylene-oxide-2-carboxylic acid is possible with the addition of alkali metal bicarbonates.  Examples are given of dyeing cotton and viscose rayon.

Title: Voltage regulators
IPC: G05F1/38
Filed: 1970-09-08
Abstract: 1329018 Automatic voltage regulation and control C L WANLASS 8 Sept 1970 [15 Sept 1969] 42928/70 Headings G3X; G3R A voltage regulator providing an AC voltage of constant RMS value from an AC supply 10, 11 comprises a saturable inductor 12 and a capacitor 13 series-connected across the supply through a switch 16, the inductor having an  inductance sufficiently large to prevent the supply alone from causing saturation, which condition is produced initially by movement of the switch arm 16<SP>1</SP> to engage contact 18 and thereby by-pass a number of turns on the inductor, after which the regulator commences operation and the arm 16<SP>1</SP> is returned to the contact 17. Alternatively saturation may be produced by other means such as a momentarily-energized winding on the inductor core 15, short circuiting of a number of inductor turns or charging the capacitor 13 by direct energy transfer thereto. Operation of the regulator consists in core saturation at a predetermined point in each half cycle of the supply 10, 11 to allow discharge of the capacitor 13, the subsequent re-charge by the action of the inductor and the supply reducing the current until the core 15 goes out of saturation. At the next change of supply polarity the above cycle is repeated, Fig. 2 (not shown). With given design parameters such as operating frequency, core material and B-H characteristic of the inductor core, the instant of core saturation in each half cycle is constant to produce a constant output voltage. If the supply volts change, the first instant after the change will alter but subsequent instants will be correspondingly changed, so that the output voltage will remain constant. The output may be taken at 20, 21 from taps on the inductor winding 14 or from a secondary winding on the core 15 whose output may be rectified, Fig. 4 (not shown) or supplied to a tapped auto-transformer Fig. 5 (not shown). Figure 6 shows a closed loop control system wherein the output voltage at terminals 54, 55 is sensed to derive an error signal, which is applied to a winding 50 on an auxiliary core 49 arranged to vary the flux-carrying capacity of the inductor core 48 and hence the instant of saturation in each half cycle. Another closed loop control system is shown in Figure 8, which uses a modified inductor comprising two cores 60, 61 and two ganged starting switches 86, 87. Series connected secondary windings 91, 92 supply a rectifier 93 whose output voltage is sensed to derive an error control signal for respective control windings 88, 89 on the cores 60, 61. Another two-core arrangement in which the output is taken from tappings on the windings 84, 85 is described, Fig. 7 (not shown). Alternatively the error signal may control the frequency of the AC supply 80, 81, which may be derived from a DC to AC converter using power transistors or silicon controlled rectifiers controlled by the error signal. If the regulator becomes overloaded the inductor stops saturating and resumes its initial high impedance state to cease the regulator operation.

Title: Electronic tester for testing devices having a high circuit density
IPC: G01R31/28
Filed: 1974-10-08
Abstract: 1477025 Computer controlled test system INTERNATIONAL BUSINESS MACHINES CORP 8 Oct 1974 [29 Oct 1973] 43443/74 Heading G1U In a computer controlled test system of the type in which a test consists of applying a sequence of m words, each of n bits, to a device under test, the fact that some words in the sequence differ from their predecessors in only a relatively few bit positions, is exploited in such a way that the m words for a complete test can effectively be stored in a storeable to store considerably fewer than m words. The principle of the invention is shown in Fig. 3, in which a store ROM 2 is assumed to be storing z words, WP1, WP2, ..., WPz, one in each vertical column, each being accompanied by x control bits. The first word WP1 is read out, and, in accordance with its control bits TP, it is transferred in parallel to n pin-energizing units PE-1, PE-2, ..., PE-n. This word constitutes the first word TW1 of the sequence of m tests words. Next, in accordance with its control bits TS, the second word WP2 is read from the store into a shift register 100. The shift register is then circulated to change sequentially the setting of the third pin-energizing unit PE-3 - the other pin-energizing units remaining in the state in which they were set by the first test word TW1 - and the resulting sequence of settings of the pin-energizing units constitute the next 100 test words, TW2 to TW101, in the sequence of test words. Next, the third word WP3 is read from the memory RAM2 and as can be seen, it is read in parallel to the pin-energizing units and constitutes test word 102. This process continues. Where successive test words differ from each other in two bit positions, it can be arranged that the shift register makes two steps before changing the setting of the appropriate pin-energizing units. Alternatively, for more complicated changes between successive words in a sequence of test words, two or more shift registers can be used.

Abstract: 1,040,758. Woodworking. AARONSON BROS. Ltd., and M. ALLEN. Oct. 30, 1963 [Nov. 19, 1962], No. 43721/62. Heading B5L. A method of producing a sheet of wood veneer comprises the steps of cutting a plurality of veneer laminations which are then formed into a shaped block having all the laminations similarly bent in order to provide two intersecting concavities in one surface of the block, and slicing from the block with a knife sheets of veneer having smooth surfaces suitable for polishing. The laminations 1 are formed from sheet stripped from a log and are arranged in a stack with adhesive therebetween and the grain of all the laminations running in parallel. The stack is placed between the dies 2, 3 of a press, the dies having a U-shaped contour in two directions at right angles so that when the stack is pressed, the stack forms a block 7 having a U- shaped surface in two directions at right angles with the grain 9 and flower 8 running in the directions shown. The curvature across the width of the block is considerably greater than that along the length. The block is then removed from the press and inverted to enable a knife 10 to move horizontally and slice veneers from the block. The block may be positioned horizontally, the flower of the veneer sheets then being in the form of complete loops, or, preferably, the block is positioned in a slightly inclined position by first removing a corner 12a, some of the flower 14 of the sheets then running substantially parallel to the edge of the sheet. Alternatively, the sheets may be sliced from a longitudinal side edge of the block or by the knife of a rotary cutting machine. The dies of the press may be modified to produce irregular flower.
