Title: Improvements relating to electrically actuated devices especially applicable to electric alarms
IPC: B61L3/06
Filed: 1916-05-13
Abstract: 166,148. Quain, J. R. May 13, 1916. Vibrations.-A contact-breaking device by vibration due for example to a passing railway train, and of the kind comprising conducting members on and between which rest loose contact members giving an intermittent contact effect when the device is vibrated, is enclosed in a bulb or case in which vacuum is maintained, or inert gas is contained, to prevent oxidation of the contacts. Parallel conducting rods a are inserted in an insulating support c cut away to expose portions of the rods on which rest loose contact members a'. The parts are enclosed in a bulb b mounted on a spring f secured for ex-( ample to a railway sleeper. According to the Provisional Specification the contact device is placed in circuit with an electromagnet, the armature oi which is normally attracted but when released, owing to increased resistance in the contact device when vibrated, is moved by a spring to close a local circuit and sound an audible alarm or effect some operation such as the actuation of points or semaphores, by known means. The armature has a leaf-spring contact so that the local circuit is not broken by vibrations, and the relay arrangement may be enclosed in a case provided with terminals for testing the battery and a plug for connecting up the contact breaker.

Patent GB-569152-A (GB)
Title: Process for manufacturing substantially saturated motor fuel hydrocarbons
Filed: 1942-05-29
Abstract: Hydrocarbons suitable as motor fuel are obtained from a butane-butene fraction, having an insufficient isobutane content for alkylation, by first increasing the paraffin, including isobutane, content and thereby reducing the ratio of olefine to paraffin present, subjecting the resulting butane-butene mixture to alkylation, fractionating the products to isolate the resulting alkylate and also the normal and isobutane fractions, subjecting the normal butane fraction to isomerisation, and introducing the isobutane so obtained as well as the isobutane fraction into the alkylation zone.  In a modification, a portion of the butane-butene fraction is alkylated, while the remainder is subjected to polymerization to yield iso-octanes.  On fractionation, hydrocarbons with four carbon atoms are separated and used in the alkylation process and the iso-octenes are hydrogenated. In the Figure, storage tank 5 receives butane-butene mixtures obtained from various sources by <PICT:0569152/IV/1> cracking, reforming, &c., and the mixture passes to a pipe 11 leading to a polymerization unit 13 and also to a pipe 45 leading to an alkylation unit 64.  Additional butanes may be admitted through pipe 49.  Metal halides, e.g. aluminium chloride, sulphuric acid or solid phosphoric acid polymerization catalyst may be used in the polymerization unit 13.  The products from the latter are fractionated in a still 16, the octenes being removed by pipe 19 to a hydrogenator 26 and the four carbon hydrocarbons are condensed and sent to the alkylation unit 64 through pipe 43. The alkylation catalyst is supplied through pipe 54. A portion of the circulating material in the alkylator 64 is withdrawn to a separator 72 from which acid is withdrawn for recirculation through pipe 73, and the gaseous products through pipe 80.  A fractionator 82 acts as a de-isobutaniser, the isobutane passing to the alkylation unit, and the residual liquid is passed to a second fractionator 96 for the recovery of normal butane and the alkylate.  The former, after a heat treatment is isomerised in unit 104 containing a metal halide catalyst, and the resulting mixture of normal and isobutanes containing dissolved hydrochloric acid collected in receiver 110.  The hydrochloric acid is preferably removed in still 120 and recirculated to the isomeriser before the butanes are passed to the de-isobutaniser 82.  In a detailed example, in which yields of the various products are given, solid phosphoric acid catalyst is used for the polymerization, sulphuric acid is used in the alkylation unit and a mixture of aluminium chloride and activated alumina is used in the isomerising unit.

Title: Improvements in or relating to a method of coating the vitreous envelope of an electric discharge device with a fluorescent powder
IPC: C09K11/02
Filed: 1947-04-12
Abstract: 639,330. Granular coatings. COLE, Ltd., E K., and EVANS, J. N. I. April 12, 1947, No. 9797. [Class 93] [Also in Group XL (a)]  Method of coating the vitreous envelope of an electric discharge device such as a low pressure mercury vapour discharge lamp with a fluorescent material comprises dispersing the powder in a dilute water solution of ammonium alginate, applying the mixture to the surface to be coated and thereafter drying and heating it in an oxidising atmosphere to remove the alginate. The proportion of ammonium alginate may be as low as about 2 per cent by weight of the fluorescent powder. The fluorescent material may be magnesium tungstate, zinc-beryllium-magnesium-manganese silicate or any powder which is not impaired by contact with the aqueous solution of ammonium alginate. An oxidising agent may be incorporated in the dispersion in order to facilitate the removal of the alginate. A mixture suitable for " daylight lamps is prepared by dissolving 50 grams of ammonium alginate (containing 40 per cent dry matter) in 2 litres of distilled water, 4 c.c. of 40 per cent formaldehyde being added as a preservative. After standing for at least 24 hours and filtering to remove suspended impurities, sufficient ammonia solution is added to bring the pH value to about 8.5. 1,700 c.c. of this solution is placed in a porcelain ball-mill together with 320 grams of fluorescent magnesium tungstate and 770 grams of fluorescent zinc-beryllium-magnesium-manganese silicate. The mixture is milled for 4 to 6 hours or for the minimum time to disperse the aggregates of fluorescent particles, and is then flowed over the interior surface of glass tubing. After draining the coating is dried in a downward-flowing current of warm air. The tubes with the adhering deposit are then raised to a temperature of about 480‹ C. to burn off the alginate, a slow stream of air being allowed to flow through the tubes and additional oxygen being introduced if desired. According to the Provisional Specification salts of alginic acid other than the ammonium salt may be used.
