Patent GB-572315-A (GB)
Title: An improved packaging machine
IPC: B65B9/06
Filed: 1943-09-09
Abstract: 572,315. Packeting tea &c. FUERY, G. T. (Millie Patent Holding Co., Inc.). Sept. 9, 1943, No. 14770. [Class 94 (i)] In a machine for forming flat packets, such as packets of tea in a form suitable for infusion, a web of porous material, such as filter paper, coated with a heat-setting adhesive is folded longitudinally into troughshape by a former, and is temporarily formed into bay-sections by travelling grippers, which engage the web transversely, so that the mouths of the bag-sections surround travelling filling-members, by which charges of tea are delivered, the bag-sections being then permanently heat-sealed at the top and sides, after which the web is cut into individual bags. The filled bags are deposited on a conveyer in groups of predetermined numbers. The paper web 41, Fig. 1, is drawn from a roll R through a former 42, and is gripped transversely by pairs of U-shaped jaws 43 carried on an endless travelling chain 43c. The jaws are closed on the web against spring action by stationary cams 43r, Fig. 4, so as to form temporary bagsections, the mouths of which are wrapped about filling-spouts 52, which, in known manner, supply uniform quantities of tea. The spouts are carried by an endless travelling chain, so as to move in synchronism with the paper web, and are raised and lowered by stationary cams 53b. After the spouts are withdrawn, the mouths of the bag - sections are temporarily closed by reciprocating presser-fingers 55, Fig. 18, after which the mouths are heatsealed by gripping between heated dies 56a, Fig. 4. At the next stage in their travel, the sides of the bag-sectons are permanently closed by heated gripping-jaws, after which the individual bags are severed by shears. The closing-fingers, sealing-members, and shears are carried on slides, which are reciprocated longitudinally of the web, so as to travel therewith in one direction. The filled bags are removed from the gripper-chain 43c by a rotating wheel 60a, Fig. 22, against the edge of which they are gripped by cam-actuated jaws 60k. The bags are released at the opposite side of the wheel and fall upon a travelling belt 61a, which is intermittently driven through a ratchetdevice, so that the bags M are deposited in separated groups. A stationary cam 62 guides the bags into position as they fall. The machine may be designed to operate on two or more bag-sections simultaneously.

Title: Improvements in or relating to television systems
IPC: H04N5/53
Filed: 1938-05-18
Abstract: 515,209. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., and WHITE, E. L. C. May 18, 1938, No. 14776. Addition to 476.935. [Classes 40 (iii) and 40 (v)] Line-synchronising signals 2 are accompanied by whiter-than-white signals 1 for gain control at a receiver, and framing signals 3 are blackerthan-black. To prevent the gain-control impulses affecting the reproduced picture, they are suppressed by separating the synchronizing signals, which are then delayed by nearly their width, broadened to exceed the gain-control pulses by adding more delayed pulses, and mixed negatively with the received signals. The delay and broadening is effected by the network shown in Fig. 2, points in the network being connected through diodes to a valve also coupled to the output of the network.

Title: Improvements in the supply of liquid fuel to internal-combustion engines
IPC: F02M9/127
Filed: 1919-06-12
Abstract: 141,003. Pifre, E. March 31, 1919, [Convention date]. Spray carburettors; vaporizers, external.-In a carburetting-device particularly adapted for use with heavy fuels, air is first admitted to the interior of the fuel-spraying nozzle, the resulting mixture being further atomized by passing through orifices communicating with the atmosphere, and being finally passed through an exhaust-heated tube to the mixing chamber, where the main air supply is received. Air enters the interior of the spraying-nozzle i from a passage l and proceeds with the fuel to the exhaust-jacketed tube v, receiving further atomizing air through an orifice r leading to an annular passage p', as well as through a port x leading to orifices u. A further supply of air enters through a tube o, under the control of a valve n<2> which is opened together with the main air inlet-valve c, both these valves being shown closed in the Figure. A throttling-valve n for the passage l is also operated together with these valves. The nozzle i is made with a conical part j<1> held against a seat by a spring j<2>. In a modified arrangement, the sectional areas of the valve n and the orifice it closes are so arranged that the supply of fuel induced by suction is independent of the extent of the suction.

Title: Improvements in the manufacture of gas and in particular of gas for the synthesis ofammonia
IPC: C10J3/46
Filed: 1949-06-02
Abstract: 677,643. Gasefying solid carbonaceous materials. COMPAGNIE PAN - EUROPEENE D'INSTALLATIONS ET D'EQUIPEMENT INDUSTRIELS. June 2, 1949 [June 8, 1948; Feb. 21, 1949], Nos. 14876/49 and 14877/49. Class 55 (i). Finely-divided carbonaceous material is suspended in a preheated gasefying mixture of air or oxygen and steam in a first zone and into the gas produced or a part of it, while still containing some ungasefied material and retaining the heat of the first operation, is introduced in a second zone a supplementary amount of oxygen and steam to continue the gasefication of the material. Powdered coal or lignite introduced into a generator 3 through a nozzle 6 is suspended in steam and air or oxygen (e.g. a mixture of 62 per cent steam and 38 per cent air) preheated to 800-1400‹ C. in one of a pair of regenerators 1, 2, and distributed through a perforated dome 5, a gas mixture being produced in which the ratio of hydrogen and carbon monoxide to nitrogen may be rather more than 2: 1. Part of this gas is diverted through a conduit 12, boiler 19, dust separator 20 and washers 21, 22, back to heat the other regenerator by combustion with air admitted through a pipe a. The rest of the gas passes through a two-pass generator 9 into the first leg of which oxygen and steam is admitted through apertures 11 to gasefy residual coal and, if desired, an additional supply resulting in a mixture in which the hydrogen and carbon monoxide to nitrogen ratio is about 3: 1 and which, after replacement of the carbon monoxide by hydrogen by reaction with steam, may be utilized for the synthesis of ammonia. The coal dust may be conveyed to the plant in nitrogen available from the oxygen-producing means. In a modification for sulphur-containing coal, a slight pre-distillation of the fuel at low temperature, e.g. 300-400‹ C., is effected by introducing it into the gas diverted into conduit 12, the temperature being regulated by by-passing a controlled portion of the gas before the point of entry of the coal. Carbon monoxide-hydrogen gases for other syntheses and composed, e.g., of H 2  46.3, CO 38.8, CO 2  14.9, may be obtained by employing steam and oxygen mixtures, e.g. in the ratio 17: 3, heated to 1000-1300‹ C., all of the gas passing from the first to the second generator. A simple shell may enclose both generators. Several plants may be operated to supply both ammonia synthesis gases and water gas &c., all the regenerators being heated by producer gas from one of them.

IPC: C08F14/24
Filed: 1951-04-11
Abstract: Polymers and copolymers of perhalo-olefines, e.g trifluorochloroethylene, are prepared by a continuous process in which the monomer is introduced into a reaction zone in the presence of a promotor, preferably a halogenated acyl peroxide, e.g. bis-trichloroacetyl, trifluoroacetyl, difluorochloroacetyl, 2-4 dichlorobenzoyl, chloroacetyl, bis-trifluorodichloropropionyl, and dichlorofluoroacetyl peroxides, at a temperature and pressure sufficient to maintain the monomer in the liquid phase so that solid polymer particles are produced in suspension in the liquid monomer. The polymer is separated and the monomer is water-washed and dried before recycling.  The promoter is injected continuously or intermittently as a solution in, e.g. trichlorofluoromethane, into the reaction zone at a temperature between -20 DEG C. and 150 DEG C. preferably below 40 DEG C.  The polymer is separated from the slurry by filtering or settling and is removed, preferably continuously, by a raking or elevating mechanism or by scraping deposits from a rotating drum, and the unreacted monomer is recycled.  The polymer may be further treated by fluorination, pyrolysis or drying.  A suitable apparatus for the polymerization of purified trifluorochloroethylene prepared from trichlorotrifluoroethane is described in Specification 712,184.

Title: Cylinder and Dial Knitting Machine
IPC: D04B15/32
Filed: 1968-04-02
Abstract: 1,181,318. Knitting-machines. SINGER CO. 2 April, 1968 [11 April, 1967]; No. 15820/68. Heading D1C. A cylinder-and-dial machine has a cam section 10, 66 for both the cylinder and the dial in which each has raise cams 12, 14 and 68, 70 and also stitch cams 38 and 92 which are all adjustable in directions substantially parallel to their respective cam surfaces. This ensures that for any adjustment for timing or setting of the needles the path followed by the needles is along lines the projections of which form angles which are invariant, as shown in Fig. 1. The setting and timing of the needle action can be adjusted accordingly, dependent on whether interlock fabric is produced on all needles or whether alternate needles are rendered inoperative in each bed for the production of a coarse rib fabric. Where a fine rib fabric is to be produced and the gating of the needles adjusted accordingly, such that all needles are operative and knit at each feeding station an auxiliary cam 44 is provided in the cylinder cam section, or it may be provided in the dial cam section, and is raised to cause the cylinder needles to be elevated to a height at which they pass the dial needles hook to hook. Subsequently the needles may be raised to knit a tuck height and subsequently. lowered by the stitch cam' or they may stay at this height until lowered by the stitch cam to welt height. The raise cams are controlled by rack and pinion mechanisms to slide in grooves in their respective cam sections and the stitch cams are adjustable by a screw control and biassed by a spring. The auxiliary cam 44 is secured by a screw clamp in an operative or inoperative position in the cam section 10.
