Title: Improvements in or relating to apparatus for supplying tobacco to a cigarette making machine
IPC: A24C5/39
Filed: 1930-03-18
Abstract: 346,547. Cigarette-making machines. MOLINS, W. E., RUAU, F. F., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. March 18, 1930, No. 8646. [Class 130.] A winnowing device for use in the tobacco feeding apparatus of cigarette machines comprises a vaned roller 8 for projecting the tobacco in an upward shower at an angle to the horizontal, a baffle board 10 arranged in the path of the shower to separate the stalks &c., and means for receiving the winnowed tobacco intercepted by the baffle board and spreading it evenly over a distributing roller 15 or a belt. As shown in the Figure, a hopper 2 is provided with a feed roller 1, carded combing and brushing rollers 3, 4, and a picker roller 5 shrouded by a trough 6 having a horizontal lip 7: A trough 11 behind the board 10 receives the stalks &c. and a board 17 prevents any of the shower from striking the roller 4. The baffie board 10 is preferably adjustable, and an air current issues from a slot 12 in the board to ensure that only heavy particles are separated from the shower, the air being admitted by an orifice 14 to the chamber 13 behind the board. The tobacco sliding down the board 10 is distributed by a vaned roller 16 upon the roller 15. In a modification, in which a feed belt replaces the roller 15, short tobacco falling between the rollers 13 is spread on the feed belt by a vaned roller, and the trough 6, 7 may be omitted.

Title: Improvements in or relating to transposed electric conductors
IPC: H01P3/00
Filed: 1953-03-31
Abstract: 724,332. Conductors. WESTERN ELECTRIC CO., Inc. March 31, 1953 [April 5, 1952], No. 8889/53. Class 36. A transposed conductor for high frequency comprises a number of smaller conductors, each in the form of a helix which continually varies in diameter first in one direction, then in the other. The composite conductor may consist of a number of conducting wires or tapes 11 applied in the form of a flattened helix around an insulating strip 13, the pitch of each tape 11 being inversely proportional to the highest transmitted frequency. If the tapes 11 are not insulated, an insulating strip is applied over one or both sides of the sheet 13, which is then rolled up as tightly as possible. The tapes 11 are connected in parallel by applying a metal cap or disc to the end of the assembly. The conductor may be made by applying tapes 11 to an insulating core 20 of circular crosssection as it is extruded from machine 21, and then passing the core through rollers 27 which flatten it into sheet 13. The sheet passes through die 28 which rolls it up to form the completed conductor 10. Insulation 29 may be applied before the rolling process.

Abstract: 550,659. Dyeing textiles. WESSON, A. J. July 15, 1941, No. 8934. [Classes 2 (iii) and 15 (ii)] Fibres, foils or films of cellulose ester or ether materials, including materials containing cellulose ester or ether fibres together with cotton, regenerated cellulose or animal fibres, are coloured by applying thereto a solution of a di- (arylamino) -anthraquinone, free from sulphonic and carboxylic groups, in an organic liquid which is a swelling agent for the materials. Specified di-(arylamino)-anthraquinones are the 1 : 4 -, 1 : 5- and 1 : 8-di-(phenylamino), 1 : 4- di - (m-tolylamino), 1 : 4 -, 1 : 5-, and 1 : 8-di- (o-methoxyphenylamino), 1: 4 - di- (o-methoxyphenylamino) - 5 - hydroxy and 1 : 4 - di - (α-naphthylamino) derivatives of anthraquinone. Specified swelling agent liquids are methyl, ethyl and isopropyl alcohols, dichlorethylene, trichlorethylene, ethylene dichloride, ethyl acetate and isopropyl acetate. Mixtures of liquids such as are described in Specification 460,575 may be used. Fabrics may be impregnated with the dye liquid by means of a padding mangle such as is described in Specifications 469,908 or 470,333. Yarns may be run through the dye liquid, squeezed and dried, an addition being preferably made to the dye liquid of an organic liquid boiling at 120-180‹C., e.g. cyclohexanol or chlorobenzene, which is a solvent for the dyestuff but has no solvent or strong swelling action on the cellulose ester or ether (cf. Specification 504,558). In an example a cellulose acetate fabric is soaked for 10 minutes in a solution at 30‹C. of 1 : 4 - di - (o - tnethoxyphenylamino)-anthraquinone in methylated spirit containing a little acetone, squeezed and dried to obtain a full blush green dyeing, fast to cross-dyeing, to light and to combustion gases. 1 : 4 - Di - (arylamino) - anthraquinones as above are obtainable by reaction of the appropriate arylamines with leuco - quinizarin. 1 : 5 - and 1 : 8 - Di - (arylamino) - anthraquinones as above are obtainable by reaction of the appropriate arylamines with 1 : 5- and 1 : 8- dichloro-anthraquinones respectively.

Machines for making and covering boxes. - Round boxes, Fig. 12, comprising a cylindrical wall b and a projecting base a united and covered by a paper strip 2 are made by mounting the wall b on a circular spring ring 21, Figs. 7 and 8, disposed between the conical edges 23, 24 of a pair of rotatable elements 19, 20 pressed apart by springs 22 and moved together to expand the spring 21 and secure the wall b. The element 19 is fixed and the element 20 is moved laterally relatively by a rotating ring member 25 which also carries the bottom a, supported on a non- rotating abutment 26 of the member 25, into contact with the edge of the body a.

Abstract: 1516501 Measuring temperature electrically T I DOMESTIC APPLICANCES Ltd 30 May 1975 [1 March 1974] 9280/74 Heading GIN [Also in Division G4] The temperature of the air leaving a tumbler dryer follows the curve shown in Fig. 2 and the rising portion 10, representing a damp-dry condition, is used to switch off the heater. As shown Fig. 1, the exhaust temperature is measured by the voltage across a thermistor X2, which is differentiated by capacitor C1 and amplifier 5 to switch on a transistor T1 at a temperature gradient set by variable feedback resistor R4, thereby shortcircuiting a relay winding Wl controlling the heater for the dryer. Thermistor X2 is preferably connected in series with thermistor X1 measuring the ambient inlet temperature to compensate for ambient temperature variations. Ganged switches S1, S2 may be operated to control transistor T1 in accordance with exhaust temperature. Alternatively the exhaust temperature is measured by a lagged and unlagged thermistor and the difference between their output signals is used to determine the damp-dry condition and switch on transistor T1.

Patent GB-825340-A (GB)
Title: A process for separating hydrocarbons
IPC: C07C7/13
Filed: 1958-03-24
Abstract: In the separation of normal hydrocarbons from mixtures of normal and non-normal hydrocarbons having from ten to twenty carbon atoms per molecule by selective adsorption on a zeolitic molecular sieve having a pore size of about 5  , the adsorbed normal hydrocarbons are desorbed by contacting the sieve with an eluting liquid comprising one or more normal hydrocarbons having less carbon atoms per molecule than the adsorbed hydrocarbons. The sieves may be used in the pure form or held in shape by 10-20% of an inert binder such as clay or alumina.  The separating step may be effected in the vapour or liquid phase at 20-500 DEG  C., the temperature being at least high enough to prevent solidification of the feed. If a wide boiling range feed is used the higher molecular weight constituents are preferentially adsorbed.  After the separation step any adhering non-normal hydrocarbons may be removed from the sieve by washing with an inert liquid or sweeping with an inert gas, such liquid or gas being free of normal hydrocarbons. The eluting liquid preferably has a carbon content of 9 atoms per molecule or less; paraffins such as propane, butane, pentane, hexane, heptane or octane are preferred but olefines can be used.  To prevent unnecessary heating and cooling of the sieve the desorption is preferably effected at the same temperature as the separation or within 100 DEG  C. thereof.  If a temperature difference is used the desorption is preferably at the higher temperature.  The eluting liquid is preferably removed before another separation step.  When separation and/or flushing and/or removal of eluting liquid are effected in the vapour phase an inert gas is preferably used with the hydrocarbon mixture, e.g. helium, hydrogen, nitrogen, methene, argon, flue gas or propane.  Throughout all stages of the process pressures of 0-35 atmospheres gauge may be used.
