[Also in Division H2] A pulse generator comprises a unijunction transistor oscillator having the control current path of a Hall plate connected in its emitterbase path. The output of the plate may be used directly to trigger a thyristor or mono- or bi-stable circuits in dependence upon the field around the plate. In Fig. 6 the capacitor discharge current of the oscillator flows through Hall plate H to produce sufficient voltage to trigger a bi-stable circuit T 1 , T 2 . The collector electrodes include the windings L 1 , L 2  of a stepping motor so that it is stepped in correspondence with a rotating magnet associated with the plate, a diode may be included in series with the Hall plate output to bias the ordinary transistor nearest to conduction (Fig. 7, not shown) and several plates may be connected to the circuit. The plate output circuit may be isolated from the input (Fig. 1, not shown). If a half or full wave rectified unsmoothed supply is used the circuit can be arranged so that the triggering threshold of the U.J.T. is exceeded only during the falling part of the cycle.

In order to purify the product the vapour may be either treated with hydrogen and the HCl and CO resulting therefrom removed by distillation or preferably be passed through one or more beds of boron containing ore heated to above 500 DEG C. preferably above 700 DEG C. but below the melting point of the ore.
Patent GB-884888-A (GB)
Title: Improvements in or relating to stabilized polyolefin compositions
IPC: C08K5/375
Filed: 1960-07-19
Abstract: Stabilized polypropylene compositions comprise polypropylene in intimate admixture with a mixture of a nickel phenolate of an o,o1-bis (p-alkylphenol) monosulphide in which the alkyl group contains 2 to 12 carbon atoms and a 2(21-hydroxyphenyl)-2,4,4-trimethyl-polyalkyl chroman, a 4(21-hydroxyphenyl)-2,2,4-trimethyl-polyalkyl chroman, or an alkylidene-bis(alkyl phenol), each aromatic nucleus of the chroman containing at least one alkyl substituent.  Many compounds which may be used in the stabilizers are listed and examples describe the stabilization of polypropylene with a mixture of 2(21-hydroxyphenyl)-2, 4, 4-trimethyl-51, 6-dimethyl chroman and 2,21-isopropylidene-bis (4-nonyl phenol) prepared by condensing acetone with nonyl phenol, and (1) nickel phenol-phenolate of o,o1-bis(p-1, 1, 3, 3 - tetramethylbutylphenol), monosulphide, (2) nickel phenol-phenolate of o,o1-bis (p-tertiary amylphenol) monosulphide and (3) nickel phenolate of o,o1-bis(p-1,1,3,3-tetramethylbutyl phenol) monosulphide. The compositions may be prepared by mixing or extruding the components, or by mixing a solution of the stabilizers in a volatile solvent, e.g. hexane or acetone, with the polymer in flake or other divided form and evaporating the solvent.  The compositions may also comprise ultra violet light absorbers, antiacids, calcium soaps such as calcium stearate, antioxidants, fillers, pigments and dyes, and may be used in the manufacture of fibres, films and tapes.ALSO:2-(21-hydroxyphenyl) chromans and 4-(21-hydroxyphenyl) chromans may be prepared by reacting alkyl phenols with acetone and mesityl oxide, respectively, in the presence of a strong acid.  In an example 2-(21-hydroxyphenyl)-2,4,4-trimethyl-51, 6-dinonylchroman is prepared in admixture with 2,21-isopropylidene-bis(4-nonylphenol), by condensing nonylphenol with acetone by saturating the mixture at 60 DEG C. with anhydrous hydrogen chloride.  Nickel phenolates of o,o1-bis(alkylphenol) monosulphides may be prepared by reacting nickel salts with the corresponding bis(alkylphenol) sulphides or the sodium phenolates thereof.  In an example the nickel phenol-phenolate and full nickel phenolate of o,o1-bis(p-1,1,3,3-tetramethylbutylphenol) monosulphide are prepared by reacting nickel acetate with the sulphide in xylene and nickel chloride with a solution of sodium in anhydrous ethanol and the sulphide.  The nickel phenol-phenolate of o,o1-bis(p-tertiaryamylphenol) monosulphide is prepared by reacting nickel chloride with the sulphide in a solution of sodium in anhydrous ethanol and hexane.

Abstract: 509,094. Roller-and-ring mills. TAYMER MILL PTY., Ltd. Aug. 31, 1938, No. 25457. Convention date, March 28. [Class 59] In a crushing and amalgamating mill, a roller 17 is set an angle to the vertical in a horizontal pan 10, whereby the convex face 17b on the bottom of the roller contacts with the bottom of the pan outside its true axial centre, giving a circle of contact concentric with its axis during rotation, and whereby the peripheral face 17a parallel to the axis of the roller contacts with the inside upwardly extending face 10a of the pan. The pan is driven through gears 13, 12 and is journalled by a sleeve 11 on a shaft 8 mounted in a footstep 2 and supported at its upper end in a casting 6 fixed to arms 4 carried by standards 3. The standards support by trunnions 20 a series of sleeves 19 for the rollers, each sleeve pressing the roller against the side of the pan by a spring 27 and also resiliently pressing the roller against the bottom of the pan by a spring 25. The spring 25 surrounds a bolt 23 screwed at one end into a cap 22 on the sleeve 19 and at its other end passes through the spindle 18 of the roller, the head 24 of the bolt allowing downward movement of the spindle. The spring 25 is compressed between an abutment 23a on the bolt and an abutment 18c in a recess in the spindle. If the mill is stopped with a pan full of material, then the screw 23 is rotated to withdraw the roller 17 from the pan for restarting the mill.
