Filed: 1929-09-19
Abstract: 319,691. British Celanese, Ltd., (Assignees of Dreyfus, C., and Lee, L. N.). Sept. 26, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Yarns, treating with liquids. - Cellulosic material, which may be in the form of yarn, is treated with nitric acid either before or after conversion into derivatives such as esters or ethers. Cellulose acetate, formate, propionate and butyrate, methyl, ethyl, and benzyl cellulose, are substances specially mentioned as suitable for such treatment. Cotton or wood pulp may be treated with 5-70 per cent solutions of nitric acid, and lower fatty acids may be present. For the treatment of already formed organic derivatives of cellulose, it is preferred to use dilute solutions of nitric acid. In one example cellulose acetate is suspended in dilute nitric acid for 3 hours at room temperature, and then dried after washing free from acid. In other examples, cotton linters are treated with strong or dilute nitric acid with or without the addition of acetic acid, and are then washed free from acid and dried, or dried without washing. They are then acetylated in known manner. Clear products are obtained which are suitable for the manufacture of artificial silk.

A method of wrapping articles, wherein a foil is supplied preferably continuously to the articles to be packaged includes guiding the foil in an air stream acting in the direction of feed of the foil to the wrapping position, the speed of the air stream being higher than the feeding speed of the foil. The foil 10 is supplied by rollers 11, 12 into a passage 13 where it is engaged by a suction air stream produced by a suction pump (not shown) fitted to the end 14 of the passage. An article to be packaged 15 is moved into contact with the foil through an orifice 16 by a slider 21, the foil being severed by a rotating cutter 25 contacting a stationary cutter 24. Owing to the continued movement of the article, the foil blank 23 is wrapped around it by edges 26, 27, further wrapping operations being performed in known manner (not shown). The foil is constantly under the action of the air stream thus preventing creasing the air entering the passage adjacent the rollers 11, 12 through the orifice and moving past the cutting device. The passage 13 is dimensioned so that when an article 21 is crossing it space is provided to allow the air stream to pass unhindered. A perforated container 28 is arranged in the passage 13 to collect any foil blanks not engaged by an article 21. The cutting device is timed in dependence upon the rate of flow of the articles.

Filed: 1929-09-19
Abstract: 319,738. Moncharmont, A. J. Sept. 27, [Convention date]. Clocks combined with gramophones.- Relates to a combined gramophone and alarm clock, and consists in a special arrangement of mechanism whereby the clock releases the gramophone at a predetermined time. In the construction shown, a casing 30 contains a clock 3 having alarm mechanism similar to that normally employed for releasing a bell, and a gramophone driven by a spring motor 2 which is located at one side of the clock. The turntable-carrying spindle extends upwardly through a partition 33 into a compartment formed by the lid 31. The means connecting the alarm mechanism with the gramophone comprises a spring arm 7 (not shown) that can be set to a predetermined position indicated by the usual, alarm setting hand. This spindle has a pin resting on a snail cam driven by the clockwork. The arm 7 carries a locking pin 11 coacting with a lever 13, which is connected by a link 15 to a lever 16 carrying a brake spring 18 adapted to bear against a drum on the governor spindle of the gramophone motor. Normally the stop 11 retains the lever 13 in the position in which the brake 18 is operative, but the arm 7 is gradually moved by the alarm mechanism until, at the set time, the stop 11 is fully withdrawn, releasing the lever 13, so that the gramophone brake is taken off. The trip-mechanism may be reset by a knob 20. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following. The apparatus may be weight-driven, or may be actuated by electric or pneumatic means. The source of energy may be common to both the gramophone and the clock, or separate and different sources of energy may be used. Various modifications may be made in the arrangement of the brake-operating mechanism. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,110,694. Moulding granular or powdered material. W. A. M. POMPE. 6 July, 1965 [6 July, 1964], No. 28638/65. Heading B5A. Powdered or granular material 5 is conveyed over a compression chamber 1, by a horizontally displaceable hopper 3, and is transferred thereto under a pro-compression pressure provided by an upper die member 8 which passes through the hopper 3 and a lower die member 2 which forms the base of the chamber 1. The die member 8 carries split dies 9 which may be set at different levels whereby localized pressure differences and compaction may be obtained over the compression chamber and the escape of air is also facilitated. Upward displacement of the member 2 against resistance provided by die member 8 then provides compaction at the unfilled bottom corners 10 of the compression chamber and raises the precompressed briquette whereby horizontal movement of hopper 3 removes excess material by scraping or cutting with a cutter (11) at the base thereof (Fig. 4, not shown) prior to replacement of die member 8 by a die (12) (Fig. 5, not shown) which completes compression of the briquette 4 which is subsequently ejected by pushing to one side by the returning filled hopper 3 after being raised by the die member 2. The hopper and die walls 6, 7 are in alignment during the precompression. Localized pressure differences may also be provided by the die 8 by spring or hydraulic means. The dies 8 and (12) may be actuated by a common pressure cylinder or, in multichamber presses, the dies 8 can be actuated by a light pressure cylinder, e.g. which has 10-20% of the force of the cylinder actuating the die (12). The lower die 2 is actuated by a separate cylinder.

Abstract: 1,181,843. Fluid-pressure servomotor systems. SANDERS ASSOCIATES INC. June 21, 1967, No.28697/67. Heading G3P. In a hydraulic servocontrol system, an electrical input signal positions flapper 24 to generate a pressure difference across the ends of spool 31 to move the latter to control the supply of fluid to opposite sides of piston 60. To render the response rate of the latter substantially independant of the magnitude and direction of its load, the spool has grooves 70, 71 which connect the low-pressure side of the jack to the pilot return chamber 78 to vary the pressure in the latter, and thus the pressure difference across the spool, according to the response of the piston. In the null position, the return chamber 78 bleeds through restriction 80; alternatively this bleed can be accommodated by underlap on the spool or by dither of the latter. The restrictions 76, 77 are temperature-sensitive.

Apparatus for permitting consumption of gas for a predetermined period comprises a normally closed gas supply valve, manually operable means for opening the valve and for putting into operation a timing device set to effect automatic closure of the valve, the timing device comprising means effecting intermittent rotation of a disc or the like carrying one or more operative pins adapted to co-operate with a member after the passage of a predetermined quantity of gas from the timing device, so as to effect closure of the valve. In the apparatus shown operation of a press button i causes a slide bar h to move to the right, allowing its left-hand end to be lifted by a spring 14 and held against a casing 21 by which movement a pin g rotates a lever f clockwise to open the gas supply valve b. Gas passes from an inlet j to an outlet m in communication with a heater, some of it passing through an orifice n at the end of a tube o into a chamber c closed by a loaded diaphragm r. The latter rises and at the end of its travel operates a flap valve p to close orifice n, and the gas in chamber c then escapes through a small orifice 17 so that diaphragm r descends, opening valve p at the end of its travel, and also, through links 13, t, u, v, rotating a ratchet wheel d through one tooth. The cycle is repeated a predetermined number of times, when a pin 5 on wheel d engages slide bar h, forcing it downwardly against spring 14 and allowing it to move to the left to its normal position, a spring 23 turning lever f anticlockwise to close supply valve b. The supply period may be varied by varying the number of detent pins 5 mounted on wheel d.
Patent GB-600118-A (GB)
Title: Improvements in or relating to the catalytic oxidation of hydrogen sulphide in gaseous mixtures
IPC: C10K1/34
Filed: 1945-10-30
Abstract: Gaseous mixtures, e.g. coal or fuel gas, are contacted in the presence of oxygen with a single solid catalyst mass comprising a sulphide or sulphides of nickel or cobalt at a temperature not exceeding 80 DEG  C., but preferably above the dew point of the mixture, to oxidize the hydrogen sulphide content to sulphur.  The process may be used to remove either hydrogen sulphide or oxygen. High humidity, e.g. 80-100 per cent of saturation and the addition of ammonia assist the reaction.  Low temperatures and oxygen concentration reduce the tendency to side reactions leading to sulphur oxides.  In examples, nickel or cobalt hydroxide or basic carbonate are treated with hydrogen sulphide at 100 DEG  C. to produce the catalysts and temperatures of 25-27 DEG  C. are used for the catalysis.  Catalyst poisoned by sulphur or sulphate may be regenerated with a solvent, e.g. carbon disulphide, aromatic hydrocarbons or preferably ammonium sulphide or by removal of sulphur by evaporation or conversion, e.g. with hydrogen, to a gaseous compound.  Oxygen may be added to the gas or adsorbed, e.g. from air on the catalyst prior to reaction, which allows countercurrent operation.  According to the Provisional Specification, temperatures up to 250 DEG  C. may be used, the catalysts may be produced by precipitation or by reduction of sulphates and may be used in gaseous suspension, on a carrier, or as a broken cake.  Specifications 241,221, [Class 38 (v)], and 276,347, [Class 1 (i)], are referred to.
