Abstract: Polyvinyl chloride compositions, vinyl chloridevinylidene chloride and vinyl chloride-vinyl acetate copolymer compositions are stabilized against heat deterioration by addition of a dialkyl, diaralkyl, diaryl or dialkaryl tin salt of a thiocarboxylic acid or of a mixture of thiocarboxylic acid and an a , b -unsaturated carboxylic acid, The specified acids are thioacetic, thiobenzoic, and mono-esters of maleic acid e.g. mono-octyl maleate.  Plasticizers (dioctyl phthalate) and lubricants (stearic acid, 'Ferrolube') may also be present.ALSO:The invention comprises dialkyl, diaralkyl, diaryl or dialkaryl tin salts of thiocarboxylic acids and dialkyl, diaralkyl, diaryl or dialkaryl tin mixed salts of thiocarboxylic acids and a , b -unsaturated carboxylic acids.  Preferably the hydrocarbon groups attached to the tin atom have from two to eight carbon atoms.  The thiocarboxylic acids are the thiono-and thiolocarboxylic acids, thioacetic and thiobenzoic acids being specified.  Mono-esters of maleic acid, especially mono-octyl maleate, are the preferred a , b -unsaturated carboxylic acid. The salts of the invention may be prepared by reacting a hydrocarbon tin oxide with a thiocarboxylic acid with or without a a , b -unsaturated carboxylic acid at a temperature between 100 DEG  and 120 DEG C., or by reacting a dihydrocarbon tin dichloride with the sodium potassium or ammonium salts of the thiocarboxylic acid and if desired of the a , b -unsaturated carboxylic acid.  In the case of the mixed acids, the weight of unsaturated acid can vary between the limits 10-90%. The prepared salts may be used as heat stabilisers in polyvinyl chloride compositions, vinyl chloride-vinylidene chloride compositions and vinyl chloride-vinyl acetate compositions.

The oscillator is a sawtooth oscillator operating by charging capacitor c by i 3  and discharging it with i 5 , the limits of sweep being determined by threshold detectors 20, 21, square wave generator 19 and a switch S 1 . In the phase comparator, current i 4  is passed by S 2  for the duration of synchronizing pulses 22 and applied via direct and inverting paths to a capacitor 23 for time intervals determined by the operation of switch S 3  controlled by the oscillator output voltage. Maximum, minimum values of the phase comparator ouput voltage are limited by 30, 31. The mean voltage across capacitor 23 causes currents i r ,i t , to change so as to vary the charge, discharge slopes of c until synchronization is achieved.

Abstract: An anti-halation layer contains artificial pyrolusite converted by heat into anhydrous form and finely divided to a grain size from 0,1 to 2,0 times that of the silver emulsion.  For example, an aqueous solution of potassium permanganate is reduced as with alcohol, the precipitate formed is separated and dried at about 130 DEG  C., ground in known manner to the desired degree of fineness, suspended in gelatin, and cast as an anti-halation layer.  Reference is made to anti-halation layers comprising pyrolusite produced in colloidal form in gelatin by causing a solution of potassium permanganate to act on gelatin, or by reducing potassium permanganate by means of manganous salts in the presence of gelatin or other colloid.

Abstract: Mycelial cultures rich in enzymes and possessing strong depilatory and proteolytic properties are obtained by growing Aspergillus oryzae from spores on a medium containing 2-10 per cent of one or more halides based on the weight of the medium and then treating the culture obtained with a plasmolising agent, such as anhydrous sodium sulphate.  The halide may be sea salt or may be formed in situ by treating a medium such as grain, oil cake or other starchy material with hydrochloric acid in order to render the nutrient material soluble and then neutralising with an alkali metal carbonate.  Formic acid may be added.

IPC: H03K3/282
Filed: 1956-08-27
Abstract: 797,329. Generating high-frequency oscillations. STANDARD TELEPHONES & CABLES, Ltd. Aug. 27, 1956, No. 26100/56. Class 40 (5). A generator of a complex electrical waveform simulates in a telephone receiver the ringing of a handbell. A multivibrator circuit comprising transistors X1, X2 generates a sawtooth pulse whose repetition rate corresponds to the pitch, fed via isolating diodes D1, D2 to resistor R6. Transistor X3 receiving bias to its base electrode by resistor R7 is cut off at the peak of each sawtooth, R6 and R7 providing a constant base current flow at each negative sawtooth peak, so that a constant amplitude pulse train, appearing at the collector, rings the circuit L, C4 which is tuned to an integral multiple of the pitch frequency. The attenuation due to striking is achieved by drawing additional current via resistor R8 and thus lowering the emitter potential of transistor X3. The multivibrator comprising transistors X5, X6, which regulates the speed of striking, generates a sawtooth wave applied to the base of transistor X4 so that resistor R8 draws more current, the amplitude of the base waveform being determined by resistor R10. The output circuit including the secondary winding of the output transformer is damped by the load across it.

Title: Improvements in spacer elements for typographical line-composing machines

Filed: 1947-09-26
Abstract: 629,442. Type-bar-making machines. INTERTYPE, Ltd. Sept. 26, 1947, No. 26161. Convention date, June 6. [Class 100 (iii)] [Also in Group XX] A spacer element for use in a typographical line-composing machine, such, for example, as disclosed in Specification 590,553, [Group XX], comprises resilient side-plates 1, 2, Fig. 5, secured together flatwise toward their upper and lower ends in parallel spaced relation and provided with portions 9, 10, 11, 12 protruding into the open space between the plates, and a member 5 shiftable fore-and-aft in the open space between alternative positions, the member having portions 7, 8, such as holes, which in the respective positions clear or encounter the protruding portions, the edgewise thickness of the element being accordingly governed by flexing of the side-plates between a parallel and an outwardly bowed position. The plates may be of spring steel, brass or plastic material, and are secured together by separators 3, 4, the resulting assembly having the marginal outlines of a standard matrix. The space between the separators provides for the sliding of the member 5 with sufficient clearance to allow for the approach towards each other of the separators when the plates are bowed. The usual high-alignment rail 21, Fig. 9, of the assembling elevator E of the normal composing machine is not required for alignment in the photo-composing machine referred to, and is provided with a longitudinal lip 22, whereby, on actuating the rail by a hand lever 28, tongues 6 of the members 5 are engaged to move all the members to the position to expand the spacers. The pointed reciprocable finger, which in the machine of Specification 590,553 engages each element on arrival at the photographing position to hold it at rest in correct optical alignment by means of a notch in the element, engages first a similar notch N in the member 5 if this has been shifted, to restore it to normal position before engaging the notches N in the side-plates. The spacer elements allow excessive line-shortage to be taken up in word-spacing before delivering the line to progressive justification of the remaining shortage between the letters and the words.
