Title: Process for producing fast colour reserves by means of ester salts of leuco vat-dyestuffs without steaming
IPC: D06P5/12
Filed: 1931-08-13
Abstract: Fast colour reserves under dyeings from diazotized 4-aminodiphenylamines and arylides of 2 : 3-oxynaphthoic acid are produced, without steaming, by printing an ester salt of a leuco vat dyestuff together with a salt of acid reaction, such as zinc or aluminium sulphate, on material which has been treated with an arylide of 2 : 3-oxynaphthoic acid, developing the ground colour by padding with a solution of a diazotized 4-aminodiphenylamine, and finally developing the colour reserve by treating in a bath containing an acid and a mild oxidizing agent, such as iron alum, hydrogen peroxide, a cupric salt or a persulphate.  In examples, goods impregnated with 2 : 3-oxynaphthoic anilide are printed after drying (1) with a paste containing the sodium salt of the disulphuric ester of leucodimethoxydibenzanthrone, Glyezine A, starch tragacanth and zinc sulphate, dried, padded with a solution of diazotized 4-amino-4<1>-methoxydiphenylamine, and passed through a bath containing copper sulphate and sulphuric acid, and (2) with a paste containing the sodium salt of the disulphuric ester of leuco-3 : 4 : 8 : 9-dibenzpyrene-5 : 10-quinone (Specifications 205,502, 220,304, and 222,125, [all in Class 2 (iii), Dyes &c.]), or of the leuco vat dyestuff from a -isatinanilide and 1-methyl-7 : 8-oxybenzocarbazole, and zinc sulphate, and further treated as in example (1), with the exception that hydrogen peroxide and sulphuric acid are used for developing the vat dyestuff; green, yellow or black effects on a blue ground are obtained.  Red effects in addition may be obtained by printing with a paste containing p-nitraniline, hydrochloric acid, sodium nitrite, starch tragacanth, and aluminium sulphate at the same time as the ester reserves are printed.  Specifications 186,057, 202,630, 202,632, 231,889, 237,295, 260,303, 267,952, [all in Class 2 (iii), Dyes &c.], 293,890, 319,021, and 332,986, [all in Class 15 (ii), Dyeing, Processes &c. for], also are referred to.

Title: Improvements in or relating to carburetters
IPC: F02M7/12
Filed: 1927-09-01
Abstract: 300,725. Morris, M. C. Sept. 1, 1927. No Patent granted (Sealing fee not paid). Spray carburettors.-In order to prevent loss of suction at the nozzle and consequent interruption of the fuel supply when the throttle valve is opened suddenly to accelerate, an automatic air valve 15 loaded by a spring or weight is located on the air inlet side of the nozzle 8 and is adapted to be under the control of the throttle valve 2 which carries an apertured sleeve G sliding over the nozzle. The valve 15, in the form of a plate, is located in a rectangular casing 14 and its lower pivoted edge is tubular to enclose the loading spring which tends to move the valve towards its closed position. The carburettor also has a ball valve 10 and plug valve 11 controlling air inlets 12, 13 and these, together with the sleeve 6, are as described in Specifications 211,910 and 240,503. With the throttle nearly closed, the air valve is in the position 15; on opening the throttle fully the air valve will move to the position 15<a> thus closing the air inlet end maintaining the suction ; as the engine speed increases the valve will be drawn by suction to the position 15<b> thus giving a full air supply.

Filed: 1935-08-16
Abstract: 446,229. Charging batteries; automatic control systems. WETZER, R., Pfronten, Bavaria, Germany. Aug. 16, 1935, No. 23077. [Class 38 (iv)] The voltage of a battery is maintained within two predetermined limits by supplying current at high or low charging rates controlled by a one contact relay which closes and opens at maximum and minimum voltage respectively, the contact pressure being increased by cutting out a series resistance after contact is made. The battery b is charged from the supply terminals k through the charging resistance r, part of which. may be short circuited by contact s actuated by resistance W1 to give the high charging rate. Contact m is then open and current flows from the battery of the relay R through moving coil B and resistance W1. When the voltage rises to the predetermined maximum, contact m closes and short circuits resistance W1, the increased current through coil B increasing the pressure of the contact. Contact S also opens and resistance r is then included in the charging circuit.

Title: Improvements in the insulation of electric wires and cables
IPC: H01B7/02
Filed: 1929-07-27
Abstract: 337,052. British Insulated Cables, Ltd., and Brislee, F. J. July 27, 1929. Insulating coverings for cables and conductors. - An electric wire or cable, with any insulation applied, is wrapped with a non-laminated strip of esterified cellulose composition which has no embedded textile support, the core so formed being heat treated to 100‹ C. so as to unite the cellulose layers into a homogeneous covering. The heat treatment may be carried out after completion of the wrapping, the cable being drawn continuously through, or left coiled in a heating chamber. A removable covering, such as a lead sheath or wrapping of strong tapes, mav be applied to maintain the shape of the cellulose strip when softened in the heat treatment. A lead sheath, applied hot, may furnish sufficient heat for the consolidation. A plastifier, such as one of the sulphonamide class, may be added up to 50 per cent by weight of the cellulose composition which should be free from solvent. An example given of a cellulose composition contains cellulose acetate, 100 parts by weight; ethyl toluene sulphonamide, 50 parts: toluene sulphonanilide, 30 parts; tricresyl phosphate, 30 parts.

Patent GB-716110-A (GB)
Title: Improved means of weighing, and for controlling the supply of material to be weighed
IPC: G01G5/04
Filed: 1950-09-22
Abstract: 716,110. Automatic feed weighers. SMALLPEICE, C. D. P. June 1 1951 [Sept. 22, 1950], No. 23248/50. Class 143 [Also in Group XXIX] A weighing mechanism includes a movable weighing member adapted for receiving the material to be weighed, a pressure regulating means adapted for supplying to a pressure gauge a pressure which increases responsively to the weight of material on the weighing member, and vice versa, and a hopper, for supplying the material, with a delivery valve operable by a fluid pressure device which is connected so as to be energized by the pressure actuating the pressure gauge such that the delivery valve will be moved to stop the flow of material from the hopper when the said pressure reaches a predetermined value. As shown in Fig. 1 the guided pan 21 is supported by a bell-crank 12 which bears against the exhaust valve member 23 of a pressure regulator, similar to that described in Specification 649,281, [Group XXIX], having an inlet valve 15 which controls the admission of compressed air from a port M and which is mounted on a sliding member 16 secured to a diaphragm 17. An annulus 22 on the member 16 is urged against the member 23 by a spring 18 and the interior of the regulator is connected through pipes 19, 29 with a pressure gauge 20 and a thrustor 27 which actuates a sliding cut-off valve 25 beneath the feed hopper 24. In operation, an increase in the weight of material in the pan 21 opens the valve 15 which remains open until the pneumatic pressure exerted on the member 23 is sufficient to return the slide member 16 to normal, whilst a decrease in weight in the pan 21 allows the member 23 to be moved away from the annulus 22 so causing the regulator to exhaust through a port E until the internal pressure is sufficiently reduced to enable the member 23 to return to normal. The pressure in the regulator is thus proportional to the weight of the load, and when this pressure reaches a predetermined value it causes the thrustor piston 26 to overcome spring 28 to close the hopper outlet. The modified arrangement shown in Fig. 2 includes a pair of valves 31, 36, each similar to that described in Specification 659,539, [Group XXIX]. In this arrangement an increase in the weight of material in pan 21 depresses plunger 30 so admitting compressed air from the main M through pipe 32 to the gauge 20, thrustor 27 and a further thrustor 33, the piston 34 of which bears on the underside of the beam 12a. After the pressure has reached a predetermined value sufficient to close valve 25, the material is removed from pan 21, the beam is raised by piston 34, so allowing valve 31 to close and opening the similar valve 36 to allow the air to exhaust through pipes 35, E.

Title: Improvements relating to methods and machines for forming and filling capsules of gelatine or like material
IPC: A61J3/07
Filed: 1957-07-24
Abstract: 881,022. Machines for forming capsules. MEHTA, M. K., and MEHTA, M. July 23, 1958 [July 24, 1957], No. 23393/57. Class 94(1). A machine for forming capsules containing granular materials simultaneously produces and fills cavities in two webs which are then sealed together and severed along the peripheries of the cavities to produce the capsules. The webs 9 pass over heater drums 1 having staggered rows of apertures, the bases of which are closed by pistons 4. Above each drum is a hopper 300 for powder, containing a helical agitator 306 and having in its base a rotary feed member 303 with pockets 301 for receiving charges of the material. As each row of filled pockets and drum apertures comes into alignment, the pistons 4 recede inwards to draw the webs into the apertures, and cam operated plungers 306 discharge the material into the cavities so formed. Just prior to the webs being nipped between the drums, the pistons 4 begin to move radially outwards so as to remove air from the cavities prior to sealing and severing continued outward movement of the pistons after sealing insures ejection of any capsules adhering to the drums. Capsules remaining on the web are ejected by a pair of rollers, Fig. 1 (not shown), between which the web passes and which rotate in the opposite direction to its movement. Each hopper may feed a different power so as to produce a capsule containing two materials. According to the Provisional Specification, a partition may be arranged to separate the materials.

Abstract: 915,091. Spray carburetters. SWEENEY, F. B. July 8, 1959 [July 8, 1958], No. 23421/59. Class 7(3) Fuel supplied at 78 by a pump passes through a suction-operated pressure regulating valve 86 to a metering valve 54 actuated in accordance with intake air flow, aerating air being bled into the fuel through a passage 174 under the control of a suction operated bleed valve 160. The valve 86 is controlled by a diaphragm 82 subjected to intake pipe suction through a passage 102 and loaded by a spring 100 adjusted by a screw 96. A suction operated accelerating device 110 is connected to the fuel supply passage 62 and a non-return valve 124 prevents backward flow of fuel therefrom to the valve 86. The fuel metering valve 54 is carried by a disc 22 actuated by air flow through the intake passage, the disc entering a small diameter part 12 of the intake passage at low air flows to render it more responsive at such flows. A bimetallic coil 138 in a chamber 128, through which air heated by the exhaust manifold is drawn, actuates a fast-idle lever 144 at cold starting to hold the throttle valve open. The coil 138 also actuates a lever 136 to pull the air bleed valve 160 downwards to close the air bleed passage 174 while the engine is cold; when the engine is warm the coil 138 releases lever 136 and the valve 160 is controlled by suction transmitted through passage 170. The lower end 56 of the fuel metering valve 54 positively cuts off the fuel flow when the engine is inoperative and during overrunning the high intake pipe suction closes valve 86 to cut off the fuel supply. The single fuel nozzle can be replaced by separate nozzles adjacent the intake valves, or the throttle valve can be situated downstream of the fuel nozzle.
