Abstract: 350,126. Trunks. FAIRBROTHER, H., 30, Ludgate Hill, London.-(Kari-Keen Manufacturing Co., Inc. ; 7th Street, Sioux City, Iowa, U.S.A.) April 7, 1930, No. 11022. [Class 18.] A trunk formed with a double wall having soft pliable cushion-like material interposed between the two parts of the wall has the -inner side of the double wall provided with ribs or corrugations for strengthening purposes. The invention is described in connection with a trunk comprising a fixed section A to which is hinged at 10 a luggagecarrying section B, the part B being fastened in the open position by a pin 14 engaging in cooperating loops on members 12. The section B includes a double bottom structure C, comprising an outer part 16, separated from an inner part 18 by a sheet 20 of pliable material such as heavy tar paper.

Title: Improvements in or relating to lamps for use on motor-cars, motor-cycles, and other vehicles
IPC: F21V11/00
Filed: 1919-05-03
Abstract: 143,013. Cooper, P. A. May 3, 1919. Vehicular lanterns.-In a vehicle head-light or head-lamp, a semicircular mirror or reflecting surface h, Fig. 1, is provided upon, or adjacent to, the upper half of the front glass so as to reflect the upwardly-directed rays from the electric bulb c or other light source back on to the parabolic reflector b, from which they are again reflected and intensify the downwardly projected beam. The mirror may be plane, rounded, or spherical, or consist of a half-lens silvered on one side. If the light source is situated between the parabolic reflector and its focus, the mirror is concave, with its centre of curvature not farther from the lamp than the virtual origin of the beam. The glass g and semicircular mirror h may be assembled together in a circumferential groove in the front of the lamp, a distance-piece or packing- strip i being fitted in the lower half of the groove. In order to obtain a sharper horizontal shadow, a U-shaped hoop or band may be secured to the front of the lamp. In another construction, Fig. 2, the mirror h is arranged in a forwardly projecting hood m on the lamp. The hood may be continued downwards, so that its lower edge is horizontal. A segmental patch may be silvered or painted on the lamp bulb so as to prevent direct rays from reaching the mirror.

Title: Improvements in or relating to galvanic batteries
IPC: H01M10/36
Filed: 1924-05-06
Abstract: 230,307. Soc. Anon le Carbone. April 10, 1924, [Convention date]. Gas batteries or accumulators have one or more porous electrodes possessing a high gas-absorbing power and covered over the whole surface with a coating such as a pectised colloid impermeable by liquids but permeable by gases. In one form the electrodes comprise carbon blocks b, c, Fig. 1, of any shape coated with a pectised colloidal film d, e, formed for example of oleo-margarate of zinc. Terminals f, g, are provided. The electrolyte h is formed for example of a concentrated solution of ammonium chloride. One ot these carbon electrodes may be replaced by a metal electrode, for instance a zinc rod, the electrolyte being a solution of chloride of zinc. In another form the electrodes are formed by a pasty mass contained in two compartments separated by a porous earth diaphragm j, Fig. 3. The mass is prepared from fecula or starch such as arrowroot flour with twice its weight of water, the emulsion being heated to 90‹ C. An equal weight of fine charcoal powder either pure or mixed with plumbago is added and then a concentrated solution of the electrolyte, say ammonium chloride. Retort carbon rods f<1>, g<1>, form electrode conductors. A layer of wax or other suitable material k hermetically seals the cell. When the electrolyte liberates one gas and one metal, the paste in one compartment is replaced by a porous vessel l, Fig. 4, of earthenware containing a concentrated solution of the electrolyte such as zinc chloride and a zinc electrode i. The vessel e has a coating of wax k<1> at its base. The electrolyte in any form may be a free liquid or may be immobilized by known processes.

IPC: C10L1/00
Filed: 1921-04-20
Abstract: Alcoholic liquids for use as fuels for internal-combustion engines, lamps &c., are prepared by distillation of fermented saccharine juices or of alcohol in presence of enriching compounds.  Saccharine juices from sugar cane, oranges, cashew, manioc, beetroot, or water melons, or solutions of molasses or raw sugar, are fermented by addition of a mixture of yeast, tannic acid, neutral potassium tartrate and sulphuric acid.  A composition consisting of the liquid obtained by boiling orange peel in water, Stockholm, coal, or petroleum tar, sulphuric acid and naphthalene is added and the mixture is distilled.  To the distillate is added a composition consisting of turpentine, ether, naphtha, animal, vegetable or mineral oils, hydrochloric acid, Stockholm, coal, or petroleum tar, and naphthalene, and the mixture is again distilled.  If alcohol is used in place of the fermented juices, a second composition of Stockholm, coal, or petroleum tar dissolved in sulphuric acid and mixed with alcohol is added prior to the first distillation.  A plant comprising fermenting-vessels, filters, heatexchangers, mixing-vessels, two stills and condensers is described.

Parts of this oxide layer are removed by grinding and the wafer exposed to zinc vapour to form diffused P-type regions. The remaining oxide layer is removed and leads are connected to the resulting diode. The semi-conductor material may be a III-V compound comprising a nitride, phosphide, arsenide or antimonide of boron, aluminium, gallium or indium or may be silicon or germanium. The oxide layer may also be magnesium oxide, titanium oxide, or aluminium oxide.

Abstract: 761,688. Supply systems for space discharge tubes; protective arrangements. GENERAL ELECTRIC CO., Ltd., ANDERSON, S., and CATES, J. April 21, 1955 [April 23, 1954], No. 11814/54. Class 38 (4). In a circuit arrangement for starting and operating on a D.C. supply at least one L.P. electric discharge lamp 1 connected in series with a stabilizing resistance R and a choke L to the circuit input terminals T1, T2 and having shunted across the lamp a starting switch S so that after connection of the circuit to the supply the opening of the switch contacts results in the production of a H.V. pulse which is applied between the lamp electrodes 3, 6 for starting the lamp discharge, a capacitor C is shunted across the choke C but not across the lamp(s) to reduce relatively high audio-frequency oscillations which may emanate from the choke L arising from ionic oscillations generated in the lamp discharge; the capacitance of the capacitor C is sufficiently great to force a relatively low impedance path across the choke for oscillations of frequency exceeding 1000 c.p.s. but is not so great that the voltage pulses produced between the lamp electrodes on openings of the starting switch contacts are insufficient to start the lamp discharge. The capacitor C may be connected, as shown, directly across the choke C, or where the resistance R is directly in series with the choke L it may be connected across both the choke and the resistance. Suitable values and construction of the choke and capacitor are described in the Specification. Also as shown, the lamp has heatable electrodes and the starting switch is of the type having a resistance heater H and normally closed contacts opened by a bimetallic strip, but the lamp may be of the cold cathode type. A radio interference suppression capacitor 8 is connected between the lamp electrodes, and where a plurality of lamps are connected in series each may have its own starting switch or there may be one switch connected across all the lamps.
