Title: Improvements in the production of polystyrene compositions
IPC: H01B3/44
Filed: 1943-01-02
Abstract: Compositions suitable for use in the manufacture of moulded articles, electrical insulating materials or coatings, e.g. on wires, comprise polystyrene in admixture with a non-polar hydrocarbon extract derived from mineral oil fractions or residues.  The extract has a boiling range of 250-850 DEG  C. at 760 mms., and an average molecular weight of 200-800, preferably 250-750, the molecules containing at least 0.6 carbon atoms per hydrogen atom.  They range from viscous oils to resinous materials of aromatic character, generally contain a proportion of unsaturated linkages and may contain a minor proportion of combined sulphur and nitrogen.  They are prepared from mineral oil fractions or residues: (1) by solvent extraction with a selective polar solvent or a mixture of solvents, one at least of which is polar, e.g. sulphur dioxide, sulphur dioxide-benzene mixtures, furfural and phenols; (2) by treatment of the fractions under pressure at low temperatures, e.g. below 25 DEG  C., with a normally gaseous paraffin, e.g. propane, or (3) by treatment of the fractions with sulphuric acid and the acid sludge separated, neutralised with alkali, e.g. caustic soda, and the desired hydrocarbons recovered by distillation, preferably in vacuo.  The extract may be incorporated directly with polystyrene or if desired before use, further refined, purified, fractionated or subjected to chemical treatment, e.g. chlorination, air-blowing or dehydrogenation with sulphur or selenium at elevated temperatures.  The composition may be prepared by mixing, followed if desired, by heating, e.g. above 100 DEG  C., to yield a plastic mass or the ingredients may be dissolved in a volatile mutual solvent, e.g. benzene or xylene, followed by removal of the solvent by distillation.  The solution may be emulsified by an aqueous medium containing an emulsifying agent, e.g. ammonium oleate.  The composition may also contain other fillers and plasticisers.

Abstract: Apparatus for producing sterile air suitable for being administered to intensive-care patients in hospitals using atmospheric air. The medical-grade air is free of gaseous contaminants and germs, at a cost substantially lower than when such air is prepared by mixing pure nitrogen with pure oxygen. Atmospheric air is compressed through at least one dry-piston compressor, condensing water vapor out of the compressed air through expansion into a buffer tank, filtering out dust particles down to micron size in a prefilter, drying the air through an adsorption desiccator unit and eliminating gaseous contaminants through an adsorption-desorption unit. A second dust filter is provided for trapping any dust released from the adsorption units. Biological contaminants, such as viruses and bacteria, are eliminated by flowing through a sequence of three biological filters of the coalescence type, and finally through a cold sterilizing unit. The desiccator unit and the unit for the elimination of gaseous contaminants contain a compound of metal oxides with silicates K, Na and Mg, the amount of this compound being larger in the elimination unit than in the desiccator unit.

Title: Improvements in or relating to apparatus for the control of machine tools by photo-cells
IPC: G05B19/06
Filed: 1935-01-04
Abstract: 447,082. Milling helical surfaces. COLLET & EN GEL HARD WERKZEUGMASCHINENFABRIK AKT.-GES., 130, Bernardstrasse, Offenbach-on-Main, Germany. Jan. 4, 1935, No. 381. Convention date, Feb. 12, 1934. [Class 83 (iii)] [See also Group XXXVIII] In a system for automatically controlling the movements of a machine tool in accordance with graphic presentations drawn on a record band, the movements are controlled by photo - electric cells which co-operate with the record. As shown, the apparatus is used for machining a propeller 3. The propeller is mounted on a table 1 rotatable by a motor 8 and is worked by a rotary cutter 13 which is movable vertically by a motor 16. The motors 8, 16 operate screwed spindles 9, 18 carrying photo-electric cells 11, 22 which are movable transversely across a record band 24 driven by a motor 27. The cell 11 co-operates with graphic records 28, 28a, 28<b> which control the oscillatory motion of the table 1, the arrangement being such that the cell 11 is driven to follow the records. The cell 22, which is mounted on a motor-driven pulley 23 and is radially adjustable in accordance with the size of the cutter 13 co-operates in a similar manner with record lines 29, 29<a>, 29b which form representations of the contour of the various sections of the propeller. Each record line shown corresponds to one half of a contour line and arrangements are made, through the intermediary of markings 30, 30<a>, 30<b> and a third cell 20, to effect reversal of motion of the cell 22 relatively to the record lines when passing from one line to the next. The cell 22 and the lines 29, 29<a>, 29<b>, &c. therefore control the vertical movement of the cutter 13. This vertical movement in conjunction with the oscillatory motion of the table is effective to produce a section of propeller which corresponds to the graphic record on the band 24. In order to ensure the same expenditure of power at a constant speed of the cutter, the oscillatory speed of the table may be controlled by providing lines 28, 28<a>, &c., the inclinations of which progressively decrease.
