Abstract: 419,989. Printing-machines. DAWSON, PAYNE, & ELLIOTT, Ltd., and STOTT, E., Atlas Works, Otley, Yorkshire. Dec. 7, 1933, No. 34397. [Class 100 (ii).] Cylinder machines.-In a single or two-colour stop cylinder machine of the Wharfedale type, means are provided for adjusting the traverse racks longitudinally relatively to the bed 3 while the machine is running so as to ensure that at different speeds of the machine the driving-pawl engages the cylinder accurately and without jar so as to ensure a smooth starting of the cylinder. This adjustment may be obtained by a rotary cam or eccentric, or as shown by means of a transversely arranged sliding cam 5 formed with an oblique upper operative part 5<x> and a lower rectangular part fitting in a transverse groove 6 in the bed plate 3. The part 5<x> engages in an oblique slot in the base plate 2 upon which the racks 1 are mounted, and the cam is operated by a screwed rod 7 mounted in a bearing and traversed by means of a pin of nuts in the form of handwheels. Back-lash is prevented by means of tapered gibs 10, 11 adjustable by clamping plates on the bed plate 3 and base plate 2 respectively.

Title: Improvements in or relating to circuits for measuring small direct voltages
IPC: G01R19/18
Filed: 1953-12-10
Abstract: 744,574. Direct voltage measurement. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 10, 1953 [Dec. 13, 1952], No. 34491/53. Class 37. A small direct voltage is measured by application to a circuit including the discharge path between two electrodes of a gas-filled discharge tube periodically ionized and de-ionized to convert the direct voltage into an alternating voltage of proportional amplitude, which is then amplified, rectified, and measured. Fig. 1 shows a gas-filled tetrode 7 comprising electrodes 14 one of which may be a thermionic cathode, which are interruptedly connected to direct voltage source 9 through limiting resistor 8 and mechanical switch 10, whereby the tube is alternately ionized and de-ionized. Between electrodes 14 are placed electrodes 11 in close proximity in the same equipotential plane of the tube discharge, and to them is applied the voltage to be measured at terminals 1, in series with the input of amplifier 5 responsive to the resulting alternating component which is amplified, rectified, and measured by instrument 6. The tube may alternatively be ionized and de-ionized by applying an alternating voltage, or a pulsating unidirectional voltage derived from the unsmoothed rectification of an alternating voltage. Fig. 2 shows a modification wherein the gas-filled tetrode 7 constitutes with its electrodes 14 in conjunction with capacitor 13 and resistance 12 a relaxation oscillator which interrupts the measuring circuit comprising electrodes 11, direct voltage source 1 and amplifier 5 at its operating frequency.

IPC: C08K5/372
Filed: 1962-09-10
Abstract: Thioether esters of formula S[CH2CH2OOC-ROH]2 where R is an ortho-hydroxy substituted aryl nucleus are made by heating 2 mols of an aromatic oxyacid with 1 mol of thiodiethyleneglycol. The reaction is preferably effected in the presence of an acid catalyst, e.g. p-toluene-sulphonic acid, and in a solvent which allows of the removal of water as an azeotope, e.g. benzene, toluene or a xylene. An example shows the preparation of the preferred ester, viz. disalycilthiodiglycol. The products are used as stabilizers of crystalline polyolefines against heat, light and ageing (see Division C3).ALSO:The invention comprises a stabilized polymer composition comprising a crystalline polyolefine and 0.02 to 2% by weight (based on olefine) of a thioether ester of formula S[(CH2)2OOC-ROH]2\t where R is an ortho hydroxy aryl nucleus. The polymers may contain, as modifiers, nitrogen containing polymers, e.g. polyvinylpyridines and polyalkyleneimines.  In an example a polypropylene is stabilized against thermally accelerated ageing, heat and sunlight; by the addition of the preferred stabilizer, viz. disalycilthiodiglycol The preparation of the esters is described in Division C2.

Title: Improvements in or relating to suspension agents for use in lacquers or other film-forming suspensions
Inventor: DREHER EMIL
IPC: C09D7/45
Filed: 1961-09-27
Abstract: The dicarboxylic acid formed by esterifying the hydroxyl groups of 2 moles of ricinoleic acid with 1 mole of an unsaturated dicarboxylic acid (which definition includes phthalic acid) or an esterifying derivative thereof, neutralised with a simple amine, polyamine or polyamide amine, dissolved in an organic solvent, comprises a suspension agent for use in a lacquer or film forming suspension. The suspension agent may be formed from the above acid and amine and dissolving the salt in the organic solvent, or by reacting the acid with the amine in the organic solvent.  The preferred amount of suspension agent is such that the lacquer contains between 0.2 to 1.2% by weight of amine salt.  Specified unsaturated dicarboxylic acids which are reacted with the ricinoleic are maleic, itaconic, citraconic, butadiene dicarboxylic, phthalic; maleic being preferred. The large list of amines includes ethanolamines, rosin amines, fatty amines, amide amines, hydroxyamines; the salts formed are soluble in most of the usual paint thinners, xylene and butanol and mixtures thereof being exemplified.  The examples which include the preparation of the maleic acid ricinoleic condensate and its reaction to form the amine salts and solutions thereof, also illustrate the benefits obtained in retarding pigment precipitation in paints and lacquer formulations.
