Abstract: 565,524. Mechanical switches; switches held set and freed mechanically. MORRISON, P. H., and PLESSEY CO., Ltd. May 6, 1943, No. 7192. [Class 38 (v)] A linear switch comprises two separate sets of stator elements, each set comprising a row of three or more contacts, one contact on each set having a common pole, a separate moving contact co-operating with each set, members sliding linearly to three positions and supporting said movable contacts which are adapted to bridge the stator contacts in pairs, or either contact may be brought into contact with appropriate single stator contacts to enable circuits to be made in a predetermined sequence. In one example, Figs. 1, 2 and 3, the switch comprises a series of sections in each of which two bridging contacts 6, borne by sliding plates 5 moved by extensions 8 of members mounted on longitudinally sliding bars 7, coact each with three or more fixed contacts 4 secured to insulating strips 2. The centre contacts of the upper and lower sets of three are connected across. By suitably positioning the sliding bars 7, the contacts 6 may bridge either two of the three or touch an end one only, whereby four separate circuit connections may be made. In this example, the bars are moved in sequence by means of projections 13 sliding in cam slots 12 cut in a rotatable sleeve 11, a " clicker " 15, 16 ensuring registration in the desired contact positions. In a modification, Fig. 9, the sliding bars 31A carry bridging contacts 6, as before, but each bar is biassed outward by springs 40, and is depressed to a biassed extent through push-buttons 33, bent-out portions 32, latching with a sliding detent 34.

Title: Improvements in or relating to the production of alkylene oxide polymers
Inventor: NEWTH FREDERICK HOWARD
IPC: C08G65/26
Filed: 1960-03-04
Abstract: Polymers of mono-epoxides are prepared by polymerizing in the presence of a catalyst comprising a mixture of two or more Friedel-Crafts type halides of elements of different groups of the Periodic Table.  The epoxides are compounds of the formula: <FORM:0878033/IV (a)/1> where R is hydrogen or may be joined to R1 to form a cycloalkyl ring, and R1 is hydrogen or a hydrocarbon or halo-hydrocarbon radical.  Examples are epichlorhydrin, ethylene oxide, propylene oxide, cyclohexene oxide and styrene oxide. Suitable Friedel-Crafts halides are aluminium trichloride and bromide, zinc chloride, ferric chloride, titanium tetrachloride, boron trifluoride and trichloride, stannic chloride, magnesium chloride, titanium trichloride, vanadium pentachloride, gallium trichloride, antimony pentachloride, tellurium tetrachloride, bismuth chloride, mercuric chloride, berrylium chloride and ferric bromide.  A solvent such as a hydrocarbon, chlorinated hydrocarbon, or ether may be present, and the catalyst may be originally in the form of a solution in e.g. benzene or petroleum ether.  After reacting, the polymer may be freed from catalyst by decomposing with alcohol, washing with mineral acid, washing with water and extracting with benzene, from which the volatile fraction is removed by distillation.  Lower molecular weight fractions may be separated from higher polymers by the use of solvents and non-solvents.
Patent GB-356286-A (GB)
Title: Manufacture of artificial threads and other products from cellulose compounds
IPC: C08B13/02
Filed: 1930-03-10
Abstract: The process of the parent Specification is modified by isolating the product of the action of one or more halogen derivatives of divalent or polyvalent alcohols on cellulose xanthate, dissolving, optionally after re-xanthation, the isolated product and working up the solution or paste thus obtained into an artificial material.  The isolation of the product is obtained by allowing it to precipitate spontaneously, or precipitation may be effected by means of an agent such as an acid, acid salt, or alcohol.  When an inorganic acid is used, the precipitate must be quickly washed and redissolved.  Viscose or other cellulosic compound containing the CSS-group such as a cellulose-xantho-fatty acid, or cellulose dixanthate may be used as the initial material. The process is applicable to the manufacture of artificial silk and other threads; films; coatings and layers; dressings for textiles, paper, leather and the like; sizing for yarns; book cloth; artificial leather; adhesives and cements; plates and plastic compositions; thickening or fixing agents for pigments in textile printing.  In an example, viscose is produced from wood pulp or cotton linters in known manner and is diluted until the solution contains about 4 per cent of cellulose xanthate.  The solution is neutralized with dilute acetic acid and stirred to remove hydrogen sulphide.  To the solution, a -dichlorohydrin is added in amount equal to about one-eighth of the weight of cellulose xanthate.  The reaction mass gradually jellifies and after one day precipitates. The mother liquor is decanted and the precipitate washed till the washings give no further precipitate with silver nitrate, and is then pressed and dried. The product which is a yellow powder is treated with caustic soda and re-xanthated with carbon bisulphide.  The xanthated product is dissolved in dilute caustic soda and after filtration and ripening is extruded into a bath of strong sulphuric acid.  The threads produced are stretched by passing between angularly spaced glass rods, and wound on a bobbin dipping into water.  The threads are then washed, purified, dried, twisted and finished in known manner.  Various modifications in the strength of the acid bath, size of orifices, temperature of the bath, length of immersion, and speed of spinning are described.  In another example, the quantity of a -dichlorohydrin added to the neutral viscose is reduced to about one-twentieth of the weight of cellulose xanthate. In another example, the viscose is not neutralized before adding the a -dichlorhydrin, and the product takes about 5 days to settle.  The product is washed thoroughly and pressed, and then, while cooled by ice-water, is dissolved in caustic soda solution.  The solution is filtered, ripened, and extruded into strong sulphuric acid at -5 DEG C.  The thread is given an extended air path and is collected on a bobbin dipping in water.

Title: Improved Means for Igniting the Charge in Internal Combustion Engines.
Inventor: BLACKSTONE GEORGE MILLS
IPC: F02B1/00
Filed: 1918-12-05
Abstract: 126,771. Blackstone, G. M., Carter, F., and Carter, E. Dec. 5, 1918. Cylinders receiving liquid fuel.-Igniting fuel is sprayed into a chamber q separated by a narrow passage from the combustion space, and is electrically ignited. The resulting flame, issuing from the chamber q, ignites the heavier fuel injected directly into the combustion space. The igniting fuel is supplied by a pipe i, and injected through two opposed orifices x, x<1>, into a stream of compressed air admitted through the central nozzle h<1>. Air-circulating passages j<1> such as are described in Specification 10163/14 may be provided. The igniting fuel may be injected into a passage communicating with the combustion space instead of into the chamber q. Separate camactuated valves may control the air used to inject the main and igniting fuels respectively, or a single cam-actuated valve may be used. In the latter case the main injection air passes also through a spring-pressed valve opened by the air pressure, which ensures that the entry of the main injection is later than that of the igniting fuel. Specification 18187/08 also is referred to.
