Filed: 1976-07-14
Abstract: 1506346 Nibbling U BENGTSSON 14 July 1976 [15 July 1975] 29329/76 Heading B3W A nibbling tool operable to cut plate 8 without reciprocating motion of either of the cutting members 2, 7 has one of the cutting members (2) set at an angle α to the axis of its carrier 1 about which the carrier is rotated to orbit the low point of this cutting member about the cutting edge of the other, stationary cutting member, thus nibbling the plate introduced between the members. As shown, the punch 2 is the orbital cutter, being journalled by a nylon or bronze bush 5 on the end of the rotatable mandrel 1. During the orbital movement, rotation of the punch 2 relatively to the die 7 is prevented by the plate, feed of which is controlled manually or numerically. The punch 2 may be square for cutting against a straight die-edge.

Title: New azo-dyestuffs containing halotriazinylamino groups and process for their manufacture
IPC: C09B62/01
Filed: 1961-08-14
Abstract: The invention comprises water-soluble azo dyes of formula <FORM:0973114/C4-C5/1> wherein R is a naphthalene residue containing three sulphonic acid groups, R1 is a benzene or naphthalene residue linked in the 1:4-positions, X is a halogenated 1,3,5-triazine residue with or without dyestuff character which is bound to the -NH- bridge through a carbon atom of the triazine ring.  The triazine residue is preferably of formula <FORM:0973114/C4-C5/2> wherein Y is a chlorine atom or an unsubstituted or substituted amino group or an etherified hydroxyl or thio group.  The dyes are prepared by condensing a corresponding amino-disazo dye, which is prepared by the usual diazotization and coupling methods, with an equimolar amount of a di- or tri-halotriazine.  If a tri-halotriazine is used the primary condensation product may be further condensed with ammonia or an amine or a hydroxyl or thio compound.  The dyes may be used to colour wool, polyamide and polyurethane fibres but are preferably used to colour cellulose fibres in the presence of alkali in red to brown shades.  In examples: (1) the disazo dye 1-aminonaphthalene - 2,5,7 - trisulphonic acid --> 1 - amino - 2,5 - dimethylbenzene --> 1 - aminonaphthalene-6-sulphonic acid is condensed with cyanuric acid is condensed with cyanuric chloride; (2) the dye specified in (1) is further condensed with 1 - amino - 4 - (41 - amino - phenylamino) - anthraquinone - 2,31 - disulphonic acid, 1 - amino - 7 - phenylazo - 8 - naphthol - 21,3,6 - trisulphonic acid, ammonia, piperidine or morpholine.

The invention relates to a process for the continuous manufacture of o-phthalic acid esters from phthalic anhydride and alkanols having 8 to 10 C-atoms, in the absence of an esterification catalyst and in the absence of a distillation aid, in which the esterification is carried out at a temperature within the range of from 180‹ to 250‹ C. to a conversion of 94 to 97% of theory, the o-phthalic acid ester thereby produced is separated from the unreacted starting products, in a liquid or vapour form, by fractionation, and the latter are again returned to the reaction, and the water of esterification is removed from the reaction mixture at the rate at which it is formed. The water of esterification is preferably removed in a heteroazotropic mixture with the alcohol by passing an inert gas through the reaction mixture. The process is described with reference to a flow diagram. Examples are given describing the preparation of the di-2-ethylhexyl-, di-n-octyl-, and di-n-decyl-o-phthalates.

Abstract: Detergent compositions contain particles of alkali metal perborate, e.g. sodium perborate, which are free-flowing and compatible with ordinary detergent mixtures and which are prepared by reacting alkali metal metaborate with hydrogen peroxide and water, the total amount of water (defined as all water present in the reaction mixture including water contained in the reactants) being such that the metaborate is at least partially undissolved, e.g. in a slurry, (the water of the liquid phase of which may be removed by heating) or there being no liquid phase at all.  The water may be removed from the slurry by a dehydrating agent, e.g. sodium sulphate.  The metaborate may be formed in situ by reacting sodium hydroxide with a sodium borate having more than one mole B2O3/mole Na2O, e.g. tetraborate.  The product granules may have a core of borate, e.g. tetraborate (from the starting material) by using less than the stoichiometric amount of caustic soda and hydrogen peroxide.ALSO:An alkali metal perborate, e.g. sodium perborate, is prepared by reacting an alkali metal metaborate with hydrogen peroxide and water, the total amount of water (defined as all water present in the reaction mixture including water contained in the reactants) being such that the metaborate is at least partially undissolved, e.g. in a slurry, the water of the liquid phase of which may be removed by heating, or there being no liquid phase at all.

Title: Improvements relating to circuits for counting electrical pulses
Inventor: MOORE DONALD FERGUS
IPC: H03K25/00
Filed: 1955-10-19
Abstract: 803,070. Pulse counting circuits. SIMMONDS AEROCESSORIES, Ltd. Oct. 10, 1956 [Oct. 19, 1955], No. 29915/55. Class 40 (6). In a counting or frequency dividing circuit of the type in which a capacitor is charged by each input pulse until when a predetermined level of charge is reached a count is recorded and in which switch means comprising a relay actuated by the output of a trigger device brings about variation in the charge on the capacitor at this point. In one condition of the relay an additional capacitor is connected to maintain it at a given level of charge and in the other condition of the relay the charge is shared between the two capacitors so that in one stable state of the trigger circuit the relay is in its first condition but when the predetermined charge level is reached the circuit triggers to its other stable state to change the relay to its second condition. The Figure shows a counting or frequency dividing circuit in which pulses from a generator 1 are fed to a " cup and bucket " circuit comprising capacitor 2 and integrating capacitor 5 so that the voltage across capacitor 5 builds up in steps, Fig. 2, not shown, the trigger circuit 18 changing its stable state when the charge on capacitor 5 reaches a predetermined level. When the voltage on capacitor 5 is less than this level relay coil 17 is unenergized and capacitor 16 is shorted through resistor 14. When the voltage on capacitor 5 reaches its predetermined value trigger 18 changes to its other stable state relay 17 is energized and capacitor 16 instantaneously carries the cathode of tube 7 to earth potential. Grid current thus flows in this tube until the rise in its cathode voltage due to capacitor 16 charging via the anode circuit of tube 7 stops the grid current flow. Capacitor 5 discharges via the grid current path of tube 7 until when capacitors 5 and 16 are at the same potential initial conditions are restored, relay 17 returns to the position shown and capacitor 16 discharges - through resistor 14. As the voltage on capacitor 5 increases the cathode of tube 7 increases in voltage until when it reaches the reference voltage applied to the grid of tube 20 diode 25 conducts so that the cathode of tube 20 rises until the tube is cut off, the rise in its anode voltage firing the trigger circuit 18. Small changes in the reference voltage increase the amplitude of the pulses from generator 1 but the bias on tube 20 varies to counteract the effect this would have on the count of the circuit. The operation of relay 17 effects a count by means of a second relay, not shown, mechanically connected to the first. The circuit may be used for counting the revolutions of the rotor of a flow meter sensing circuit as described in Specification 803,069, [Group XXXVIII], the output of the sensing coils of this unit being amplified and fed to control the output frequency of pulse generator 1.
