Abstract: 464,761. Extrusion machines. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., HILL, H., BECKINSALE, S., SLATER, W. F., HENLEY EXTRUSION MACHINE CO., Ltd., and DUNSHEATH, P. Sept. 21, 1935, Nos. 26200 and 28717. [Class 87 (ii)] [Also in Group XXII] Material such as lead or rubber is extruded by two members of disc form which are arranged coaxially, and have spiral propelling means on one or both of the adjacent faces. A spiral groove may coact with a smooth surface for the extrusion of rubber. The discs may be flat, conical, or of curved profile. An annular disc 5, Fig. 1, is rotated within a casing 3, 4 by means of gear teeth 6 on its periphery, and has spiral grooves 14 formed in both faces which co-operate with ribs 13 in the walls of the casing to extrude lead, delivered by passages 10, into a chamber 20 and between a die 22 and counter die 21 for the formation of a cable sheath. Control of the temperature is effected by air or water-cooled ribs 16, and by heating means 18, a separating layer 19 of asbestos being provided. In a modification, a number of discs 32, Fig. 4, are mounted for rotation in annular recesses in the body 30 of the machine, and are driven from a gear 39 through the casing 35 and rods 33 passing through holes in the casing and discs. Lead is supplied through an inlet 42 to an annular passage 44, and passes to the discs by which it is forced into the chamber through orifices 49, and is extruded between the die 52 and counterdie 51. Cooling passages 46, 47, 48 are formed in the body of the machine, and additional temperature controlling means may be provided. The apparatus is modified for the extrusion of rubber by the provision of a hopper feed in place of the pipe 42, and by alteration of the temperature controlling devices.

Title: Method for thy hydrogenation of unsaturated oils
IPC: B01J19/00
Filed: 1971-04-19
Abstract: 1349528 Temperature control of oil hydrogenation, evaporating and condensing CHEMETRON CORP 19 April 1971 [8 April 1970] 26245/71 Headings B1B B1F and B1X [Also in Division C5] A method for the batch hydrogenation of unsaturated oil comprises heating the oil by heat exchange with a condensable heat exchange medium, e.g. steam, and condensing at least some of the heat exchange medium under a first pressure with heat exchange with the oil to provide a body of liquid medium in thermal communication with the heated oil, introducing hydrogen into the heated oil to establish an exothermic hydrogenation reaction, removing heat from the reacting oil to control hydrogenation temperature by allowing heat exchange medium to vaporize from the body of liquid medium under a second pressure lower than the said first pressure, and subsequently further reducing the pressure over the body of liquid medium to cool the hydrogenated oil to filtering temperature. In the figure, a batch of soybean oil with catalyst is introduced into the vessel 10 through 14. Valves 56 and 67 are closed and valve 52 is opened to admit steam at 150 p.s.i.g. into the upper end of coil 48. Condensate valve 62 is opened and the steam heats the oil to 300F. Condensate valve 62 is closed and steam condenses in the coil until the coil is 50-75% full. Valve 52 is closed, and valves 56 and 67 are opened. Hydrogen is introduced at 5 p.s.i.g. through sparger 32. As the oil temperature rises, control regulator valve 90 begins to open and drains condensate from condenser 76 into the lower end of the heat exchange coil 48. As heat is generated by the hydrogenation it is absorbed by vaporization of the coolant in coil 48. As coolant vaporises more liquid coolant is introduced into the lower end of the coil until a state of equilibrium exists, the vapour from the coolant passing through vapour 54 to separator 58, and dry vapour is condensed in condenser 76 by water coolant. When hydrogenation is complete, all the condensate is drained from condenser 76 and causes reduction in pressure in the condensing system.

Abstract: 1468858 Emulsified dispersions of photographic developing agents FUJI PHOTO FILM CO Ltd 14 June 1974 [14 June 1973] 26602/74 Heading G2C An emulsified dispersion of a photographic developing agent is prepared by (i) dispersing droplets of a solution of a developing agent, which is dissolved in an organic hydropholic solvent having a boiling point of more than 150‹C, in an aqueous hydrophilic organic colloid solution and (ii) mixing the resulting dispersion with a polymer latex, the polymer being an addition polymer having a carbon chain backbone. The developing agent may be a dye developer (see Example 1 and 3) or an auxiliary developing agent (see Example 2). The hydrophilic organic colloid may be gelatin, a gelatin derivative, a cellulose derivative, a soluble. starch or a synthetic hydrophilic polymer. The polymer latex may comprise particles of which at least 80% by number have a size of less than I micron and comprise 15-25wt. per cent. polymer, the balance being water. The polymer of the latex may have a molecular weight of 1,000-100,000, and may be polyethyl acrylate (Example 1), polybutyl methacrylate (Example 2) or methyl acrylatevinyl chloride copolymer (Example 3). The dispersed particles of developing agent are more finely dispersed by the polymer latex especially if the latter is compatible with the water-insoluble solvent in which the developing agent is dissolved. The latex inhibits crystallization of the developing agent and breakdown of the emulsified dispersion and also inhibits migration of residual waterinsoluble solvent in the coating to the surface of the coating after drying.

Title: Method and apparatus for measuring the mass flow rate of gaseous hydrocarbons
IPC: G01F1/88
Filed: 1965-06-23
Abstract: 1,089,860. Measuring mass flow-rate of gases ROCHAR ELECTRONIQUE. June 23, 1965 [June 24, 1964], No. 26651/65. Heading G1N. The mass flow-rate of a gaseous hydrocarbon is determined electrically by measuring the volumetric rate of flow, using a Venturi, and determining the apparent density p a  using a known relationship between the upstream pressure P and temperature T. The inverse of # a  is given by W = k o  T/P + Y(T), where the function Y(T) is predetermined experimentally. The upstream temperature T is measured electrically at 40, and the signal voltage applied to a rheostat 38. The upstream pressure P is measured at 30 and the slider of rheostat 38 adjusted accordingly to give T/P. The constant k o  of the above equation for W is obtained by the feedback amplifier 44 to give k o  T/P. The temperature signal T is also fed through a function generator 48 to give Y(T). These components are added at 50 to give W = k, T/P + Y(T). The mass flow-rate D m  is given by D m  = C#fa.#P = C##P/W, where C is a constant, and #P is the differential pressure measured across the Venturi constriction at 18, 20. A monostable multi-vibrator 58 has its pulse frequency F determined by a voltage/frequency converter 54, and pulse duration controlled at electrode 60 by the signal W. The output is integrated at 62 to give FW, and used to control the pulse duration of a second, similar monostable multi-vibrator 64 whose pulse frequency is also F, the output being integrated at 68 to give F<SP>2</SP> W. This signal is composed with the differential pressure signal #P measured at 26 in a feedback loop to make them equal. Thus #P = F<SP>2</SP> W or F = ##P/W, making F proportional to D m , the mass flow-rate. The frequency F is measured at 70, and integrated by a pulse counter 72 to give the total flow weight.

Abstract: 1,180,509. Vehicle bale-loading device. A. EBERHARDT, and D. EBERHARDT. 7 June, 1968 [9 June, 1967; 14 June, 1967 (2)], No. 27092/68. Heading B8E. A vehicle for bales of straw &c. includes a pivotable member 38 which, after a bale has been raised through an aperture 2 in the floor of the vehicle, prevents the bale from falling. In Fig. 3 a bale 13 from a pick-up device 14 is raised through the aperture 2 by a lifting device 6 actuated by an hydraulic cylinder 10. Lowering the device 6 allows the bale, under the control of the pivotable member 38 to engage, a rest 39 which may be a roller. The stack is formed by the lifting of successive bales and is pushed rearwardly of the vehicle by a wall 17 and by a conveyer on the vehicle floor. A cylinder 25 drives the wall and the conveyer but the latter may be driven independently for unloading the bales at the rear of the vehicle. The desired height of the stacks can be set by an adjustable stop 68 or the number of bales in a stack may be controlled by a counter (69), Fig. 7 (not shown). To prevent tilting of the completed stacks, supports 73 pivoted to the wall 17 are raised during the forming of each stack, Fig. 2. For unloading, a rear wall 18 is movable to a position 18<SP>1</SP>, but a stack which is moved beyond the floor of the vehicle is prevented from immediately falling on to an elevator 47 by a device 42-46. This is actuated by a lever when it is desired to load the elevator for transfer of the stack for storage. The pickup device 14 may comprise conveyer chains fitted with hooks but in Fig. 8 a channel is provided with driven wheels 109-111 having prongs which project through the base 106 of the channels to feed the bales to the lifting device 6. The pick-up device has a groundengaging skid 124 and is mounted for pivotal movement into a transportation position. Modified pivotal constructions are described with regard to Figs. 12 and 13 (not shown). Fig. 7 (not shown), is a diagrammatic representation of how the cylinders (10, 25), the front wall (17) and the lifting device (6) are automatically controlled.
