Title: Improvements in and relating to fuel pumps for internal combustion engines
IPC: F02D1/00
Filed: 1928-11-12
Abstract: 328,306. Winckler, A. E., and Hughes, E. S. Nov. 12, 1928. Divided on 333,545. Actuating by cams and toothed gearing; timing- devices; multiple-acting piston pumps; regulating by opening suction valves.-The plungers I' of a multi-cylinder fuel pump for an internal-combustion engine are driven through worm gearing, shafts H<1>, H, a swash-plate L', and connecting rods l<7> which are ball-jointed to the swash-plate and plungers. The shaft H<1> has a helically grooved portion h<16> engaged by a grooved sleeve h<17> which engages also a ribbed portion of the shaft H and is axially slidable by mechanism 90, 93, 97 to turn the shaft H<1> and alter the timing of the fuel feed relatively to the piston movements of the engine. The delivery of the pumps is regulated by opening the inlet valves k<2> for a variable portion of the delivery strokes by means of an adjustable compound cam o, o<1>, o<2> driven by an extension of the shaft H and operating the valve rods k<3> through swinging arms p<7> and rocking levers p. The period of opening of the valves is adjusted by axial movement of a helically ribbed portion h<7> of the shaft driving the cams, thereby adjusting the rise of the cams. The operation of the valves k<2> is automatically controlled in accordance with the pressure of the lubricating system of the engine by means of a flexible chamber s<6> open on the inside to the pressure of the lubricant, and operatively connected to a clutch member in a manual control mechanism for adjusting the cams o, o<1>, o<2>. If the pressure of the lubricant fails, the clutch is opened so that the manual control is inoperative, and the cams automatically return to neutral position, so that the valves k<2> remain open and the pump ceases to deliver.

Title: Conversion of carbon compounds, water and air to hydrogen and electrical energy
IPC: C02F1/16
Filed: 1959-06-29
Abstract: <PICT:0930103/III/1> In a process for producing hydrogen and possibly carbon monoxide from particulate carbonaceous materials, e.g. coal, coke, lignite, oil residues, there is employed a heated reaction chamber containing fuel cells with passages 29 traversed by a mixture of particulate carbonaceous material and steam introduced through lines 5 and 9 respectively and passages 20 traversed by air and which produce electrical energy and a hot gas containing CO2 which is mixed with particulate carbonaceous material and CO2 introduced at 51 and 3, the resulting entrained steam being heated in a heater 33 and allowed to react as it descends chamber 36 to produce a gas containing principally carbon monoxide, the latter being subsequently mixed with steam and converted to H2 and CO2, in the presence of a catalyst, CO2 separated from the resulting gas being recycled to the reaction chamber.  If an excess of CO is produced in the process a portion may be used to generate steam to drive a turbine connected to a generator to produce additional electrical energy.  To provide additional residence time the reacting mixture comprising particulate carbonaceous material and CO2 may traverse a series of pairs of reaction chambers, one chamber of each pair having a heating unit in an upper portion thereof and fuel cells in a lower portion.  Ash may be withdrawn from the base of the reaction chambers by a screw conveyer 39.  CO-containing gas may be fed via line 43 into the mixture traversing the fuel cell passages 29 and in a modification may replace the mixture of carbonaceous material and steam supplied to the fuel cell passage. Cooling coils to control the temperature of the gas recycled to the fuel cells may be provided.

Patent GB-480107-A (GB)
Title: Improvements in and relating to the refining of metals
IPC: C22B15/14
Filed: 1936-08-13
Abstract: In the refining of metals, and more particularly electrolytic copper, the metals are first heated in an electric radiating furnace to 900-1000 DEG  C., so as to avoid melting whilst protecting them from the atmosphere until the major part of the occluded hydrogen has escaped, the metals being afterwards melted in the same furnace and then cast immediately while protected from the action of the atmosphere.  When treating copper cathodes, they are placed on charcoal in the furnace before being heated.  Other metals such as iron, cobalt nickel and aluminium may also be refined in the same manner.

Title: Improvements in or relating to the coating of glass fibrous materials with perfluorocarbon polymers
Inventor: BLACKIE IAN
IPC: H05K1/03
Filed: 1960-06-29
Abstract: Dispersing/wetting agents are removed from glass fabrics coated with a perfluorocarbon polymer, e.g. polytetrafluoroethylene, from a colloidal solution containing such dispersing/wetting agents by subjecting the coated fabrics to the action of a solvent for such agents for extraction thereof.  The colloidal solution used for the coating may be an aqueous dispersion or an organosol.  The dispersing/wetting agents may be non-ionic long chain ethers or alcohols or salts of long chain sulphonated acids and suitable solvents are aromatic hydrocarbons, chlorinated hydrocarbons, ethers and ketones, e.g. the monomethyl ether of ethylene glycol. The dispersion medium may first be removed by heating the coated fabrics at a temperature and for a sufficient time to effect volatilization and further coatings may then be applied, the solvent extraction taking place after each coating or after the last coating.  After the solvent extraction plies of the coated fabrics may be heated under pressure to sinter and coalesce the polymer.  The process is applicable to the manufacture of polytetrafluoroethylene/glassfibre laminates which are provided on one or more surfaces with a layer of copper for use in the electrical and electronic industries for the production of printed circuits by appropriate etching of the copper.ALSO:Dispersing/wetting agents are removed from glass fibrous materials coated with a perfluoro carbon polymer, e.g. polytetrafluoroethylene, from a colloidal solution containing such dispersing/wetting agents by subjecting the coated materials to the action of a solvent for such agents for extraction thereof.

Abstract: 1312005 Vehicle identification SUMITOMO ELECTRIC INDUSTRIES Ltd 12 May 1970 [13 May 1969 (2) 14 May 1969 16 May 1969 23 July 1969 7 Aug 1969] 22907/70 Heading B7N [Also in Division G1] In an arrangement for reading a code label 8 formed of horizontal retroreflective stripes on an object moving along a predetermined track, e.g. a rail vehicle, in which the label is scanned vertically by light from source 4 reflected from a rotating mirror drum 7, the light beam is modified by a lens arrangement 5 to illuminate an elliptical portion of the label having a width less than and a length approximately equal to that of each stripe. The stripes on the label are formed into vertical columns each providing a binary representation of two or more decimal numbers and a column identification code. The lens unit 5 carries one or more lenses inclined with respect to the beam axis so as to focus the source on to the required area of the label, the light reflected from the label passes via partially reflecting mirror 6, lens 9, slit mask 10 and filter 11 to the light sensitive device 12 which provides an output signal to the processing equipment. Each label is formed of 5 vertical columns I-V each including two broken line portions carrying a unit as shown in Fig. 4b. Each unit includes six narrow stripes 42 defining two wide (binary 1) and three narrow (binary 0) intervals thus being able to represent a decimal digit in a 2 from 5 code. The columns are also each provided with three broad stripes 41 disposed so that the columns can be identified by comparing the time intervals between broad stripes with predetermined intervals or by counting the number of narrow stripes between broad stripes or both. The labels can be preformed with each unit represented as 8 narrow stripes two of which are blanked out to form the two wide intervals or the stripes can be formed on rotatable members which can be rotated to "stripe present" or "stripe absent" positions. The signals from the light sensitive device are sorted into wide and narrow pulses in discriminator 101. The narrow ones in channel 2 are applied to interval discriminator 102 which passes the binary information after parity check in unit 106 to shift register 107. The broad pulses are supplied to discriminator 103 which compares the pulse intervals with two set values to energize channels A, B or C in dependence on the result. The channels and the outputs from the narrow and wide pulse counters 104, 105 are applied to column discriminator 104 which energizes gates 109 to route the information stored in register 107 to the correct position in the buffer register 110.

Title: Improvements in and relating to electric batteries
IPC: H01M50/463
Filed: 1931-08-14
Abstract: 388,026. Galvanic batteries. JENKINS, H. C., 815, Salisbury House, London Wall, London. Aug. 14, 1931, No. 22992. [Class 53.] An - electric cell having a number of interleaved positive and negative plates is provided with an insulating member 6 which engages the plate lugs and separates the two groups of plates. The positive electrodes 1 may be of graphite and are provided with extensions 2 which have apertures 4 for receiving bolts which may be used as the terminals. Graphite pieces 3 are inserted between the extensions 2 and are also threaded on the bolts to keep the plates at the required distance. The negative plates are assembled in a similar manner, but if they are made of metal the extensions 2 are smaller, and metal washers take the place of the distance-pieces 3. The member 6 is in the form of a double comb the prongs of which pass between the plates and beneath the members 3, thus preventing contact between the two sets of plates. Two insulating end-plates 5 drilled to receive the bolts, and shaped as shown in Fig. 7, are provided. The assemblage is completed by a bar 13 which is held to the casing by a bolt and nut. The terminal contacts may be made in the form of clamps having thimbles for connection to a cable. Cells may be joined in series by simple pressure between horizontally projecting pieces which may be electroplated and have wire gauze between their contacting faces. The graphite electrode may be covered with carbon granules provided with an absorbent for bromine or chlorine and enclosed in a porous cover, and the lugs of the electrode may be impregnated with paraffin. The negative electrode may be of graphite on which zinc is deposited from an electrolyte of zinc chloride and bromide containing also acetic acid. On discharge the zinc dissolves and is re-precipitated when the cell is again charged. Manganese oxides may also be used with the positive graphite electrodes, the negatives consisting of zinc. When granular materials are used with the positive electrodes they are held in place by a fabric cover and a sealing material which is hardened by heat, chemical or other treatment. Pressure may be applied during the hardening process by the use of a temporary zinc or aluminium cover which encloses the fabric cover while it is in the press. The metal cover is finally removed by solution in acid or alkali. Specification 324,918, [Class 53, Galvanic batteries], is referred to in the Provisional Specification.

Title: Improvements in knitting machines
IPC: D04B11/00
Filed: 1936-08-21
Abstract: 480,686. Knitting-machines. MILLER, M. C. Aug. 21, 1936, No. 23082. Convention date, Jan. 15. [Class 74 (ii)] A straight-bar knitting-machine is provided with knock-over elements 47 each having a knock-over surface 102 ending in a throat 104 by which a sinker loop of a previously knitted course is engaged to bring the needle loops of that course to the back of the adjacent needles prior to the raising of the needles. Each section of knock-over elements 47 is supported upon a bar 108 pivotally mounted on a lever arm 110 and pressed upwards by a compression spring 114. The upward movement of the bar 108 and elements 47 is limited by a stop screw 118 engaging a lug 116 on the bar. The arm 110 is loosely mounted upon a rock-shaft 112 extending the length of the machine. To impart movement to the arm 110 and to the bar 108, a lever 122 is rigidly secured to the shaft 112 and is connected to the arm 110 by a tension spring 124. A stop screw 130 on the lever 122 engages an abutment 132 on the arm 110. One or more cam levers 134 are also secured upon the shaft 112 and carry rolls 136 which engage alternatively cams 138, 140 on a cam shaft 44. The cam 138 is engaged by the roll 136 during ordinary knitting; upon axial movement of the shaft 112, the roll engages the cam 140 during fashioning operations. The provision of such hooked or throated bits 47 allows the usual rapid outward and return movements of the needles to be dispensed with, and as shown by the chain-dotted lines in Fig. 26, only enough horizontal movement of the needles to cause the needle beards to clear the press edge 49 and to draw the newly formed kinks off the noses of the sinkers 46 is required. Further, during narrowing, the throats of the knock-over elements 47 hold the loops and ensure that those loops not transferred by the points 56, Fig. 23, will be held to the rear of the needles 48 as the needles rise. While the loops to be transferred are being shed from their needles, and the needles are moving to their lowest position, the loops are drawn over the surfaces 102 of the element 47, and since the elements can move downwards against the spring 114, the loops are accurately repositioned if they have become distorted. A table or carrier 150, Fig. 4, is pivotally mounted so as to extend close to the knock-over bits 47 to support the knitted fabric as it is taken up from the needles.
