Title: Manufacture and Packaging of Cooking Fats
IPC: A23D9/02
Filed: 1966-03-04
Abstract: 1,170,081. Coated fat compositions. UNILEVER Ltd. 24 Feb., 1967 [4 March, 1966], No. 9526/66. Heading B2K. [Also in Divisions B8 and C5] Cooking fat used in confectionery processes where it is usual to cut portions from a block, is formed into a rod which is coated with a material preventing adhesion e.g. hard fat, edible protein or carbohydrate, the rod being cut to ready use portions and packed in a bag &c. Methods of preparing and extruding various fats are described the adhesion preventing material being showered on the rod as it leaves the extruder and is cut by a reciprocating wire. The cut lengths fall on a screen conveyer where excess coating falls away. Alternatively an air blast removes the excess. In one method of preparation of a pastry margarine, the emulsified fat at a temperature of 40‹-50‹C., is chilled by passing through an annular space between an outer chilled scraped metal surface and an inner surface, passed through a region where further crystallisation occurs and then is worked by passing it through fine orifices e.g. through screens. Alternatively chilling may be effected by feeding warm emulsion to a chilled rotary surface and scraping it off. The final outlet is a die plate through which the rods are extruded. The rods may be composite and have a matrix of flexible cooking fat with one or more cores of soft cooking fat, e.g. shortening, formed by extending the matrix through a main aperture surrounding die apertures for the cores.

Title: Improvements in and relating to Means for Avoiding Destructive Stresses of Torsion when Transmitting Power between Two Shafts.
Inventor: GEORGE EDWARDS
IPC: F16H1/20
Filed: 1917-07-04
Abstract: 108,471. Edwards, G. July 31, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Toothed gearing; toothed wheels and pinions; belt gearing; pulleys.-Relates to means for avoid. ing stresses and torsion when transmitting power between two shafts such as those used with steamturbines for marine propulsion or rolling-mills. Toothed pinions, formed on or rigidly connected with a driving-shaft, gear with wheels on a driven shaft resiliently mounted in such a manner as to be relatively displaceable and render substantially equal the power transmitted through each of the wheels, thus causing an equal distribution of load along the shafts. The power is transmitted through the resilient means employed, and the wheels on the driven shaft are capable of being used in series. In the form shown, a series of double helical pinions 6, integral with a shaft 1 coupled to a turoine, drive pairs of relatively displaceable helical wheel-rims 7, 7<1>, resiliently counted on the driven shaft 3. The pairs of rims 7, 7<1> are loosely mounted on drums 8, Figs. 3 and 5, fixed on the shaft 3 and are each connected by internal projecticns with the ends of arms 17 loose on the shaft 3. The arms 17 pass through circumferential slots 19 in the drums 8, and are connected by springs 24 adjustably supported on ball joints, with projections 23<1> on the drums. Two or more pairs of helical rims may be carried on a single drum, and two drums, each carrying two pairs of rims 7, 7<1>, may be mounted on a shaft with a bearing between them. The shaft 1 is mounted in bearings 2, 2<1>, and the shaft 3 in bearings 4, 4<1>, in a casing. Belts may be used instead of teeth on the rims 7, 7<1>. All the springs 24 may have the same length without load and the same flexibility, or the springs may have the same length without load but vary in stiffness according to their position on the shaft 3.

Abstract: 1,261,304. Boring earth. INSTITUT GORNOGO DELA SIBIRSKOGO OTDELENIA AN SSSR. 27 Feb., 1970, No. 9699/70. Heading E1F. A pneumatic percussion device for making holes in the ground by packing the latter comprises a housing I with a pointed front portion, a striker 2 which divides the interior of the housing into front and rear chambers 3 and 4, a compressed air feed pipe 7 extending into the shank of the striker, and a sleeve 11 on the pipe and which is movable on movement of the striker alternatively to open and close an aperture 9 in the pipe leading to the rear working chamber 4. The sleeve is moved by a pin 14 on the striker engaging one of the ribs 12, 13 on the sleeve. At the end of the forward stroke of the striker which impacts against the housing to move it forwardly, air is fed to the chamber 3 through openings 6 from the end of pipe 7 to return the striker. In the embodiment shown air is alternatively exhausted from the chambers 3 and 4 through opening 16 into pipe 15, while the striker can be arranged to impart rearward impacts to the housing to withdraw it from the hole by moving pipe 7 backwards relative to the housing by means of thread 18. In another embodiment air is exhausted from chambers 3 and 4 through an aperture in the housing uncovered by movement of the striker.

Abstract: 746,207. Turbines. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM April 5, 1954, No. 9904/54. Class 110(3) A turbine casing comprises two halves connected together along a plane at right angles to the axis of the turbine by means of a ring, composed of two or more parts bolted together, formed with an annular groove at its inner periphery which engages radial flanges on the two halves of the casing, together with ribs and grooves on the two halves of the casing which cooperate to locate the two halves with respect to each other and some or all of which form a labyrinth packing for driving fluid leaking through the joint. The contrarotating radial flow back pressure turbine shown comprises two shafts 1 which support the turbine discs 2 and blades 3. Steam is admitted to the turbine through the channels 4. The turbine casing 7 consists of two halves which are connected together along a plane at right angles to the axis of the turbine by a ring 9 which is split along a diameter and the two parts bolted together. The ring 9 has an annular groove on its inner periphery which engages the radial casing flanges 8. Annular ribs and grooves 10 locate the two casing halves with respect to each other. The ribs and grooves next to the inside of the casing form a labyrinth packing for the steam leaking through the joint. This steam is led through passages 11, 12 to a leakage condenser. The annular groove outside the passage 11 is provided with an elastic packing 13. Clearances between the tops of the ribs and bottoms of the groove and between the flanges 8 and the bottom of the groove in the ring 9 allow for axial and radial expansions of the casing. The packing 13 may be formed by an elastic ring which forces the flanges against the sides of the groove in the ring 9. In a modification, Fig. 4, the packing 13 consists of two conical rings 15, the inner peripheries of which are caulked in grooves formed in the flanges 8. After the casing halves have been assembled, the rings 15 are welded together at their outer periphery. This weld is broken when the casing is parted.

Abstract: 148,613. Tod, D. V., and Caledonia Manufacturing Co. April 22, 1919. Boilers.-In water heaters or boilers of the type in which the combustion chamber is enclosed by a number of water-tubes converging at their upper ends and communicating with a superposed water chamber, each water-tube is constructed as a separate unit connected at its upper and lower ends by detachable connexions to the adjacent tubes so that any tube is readily removable. The tubes may thus be interchanged or replaced by a distance block facilitating cleaning &c. The water passes from the superposed chamber down a centrally-disposed tube to the lower ends of the water tubes, returning through uptake pipes to the tank. In one example water stored in the tank passes down the pipe 9 to the lower ends of pipes 3, which are bolted together at their upper and lower ends in series and returns to the tank by the pipes 10.

Abstract: Novel molecular chimaeras produced by recombinant DNA techniques are described. They comprise a target tissue specific transcriptional regulatory sequence (TRS) linked and controlling the expression of a heterologous enzyme for example Varicella Zoster Virus Thymidine Kinase (VZV TK) gene. A molecular chimaera is packaged into a synthetic retroviral particle which is capable of infecting mammalian tissue. This in turn may be administered to a patient, and the TRS will be selectively transcriptionally activated in the target tissue (for example cancerous tissue). Administration of compounds which are selectively metabolised by the enzyme produce cytotoxic or cytostatic metabolites insitu thereby selectively killing or arresting the growth of the target cell.
