Title: Spinneret
IPC: D01D5/34
Filed: 1963-08-01
Abstract: A spinneret for producing crimpable multicomponent fibres of heterogeneous cross-section comprises at least one orifice plate, and at least one orifice back plate spaced narrowly apart, each of said plates having a plurality of orifices whereby each of the orifices in the back plate is in alignment with one of the orifices in the orifice plate such that a first (core) fibre-forming component may be supplied through the orifices of the back plate to the orifices of the orifice plate, and a second (sheath) fibre-forming component may be supplied between the plates in a direction perpendicular to the supply of the first fibre-forming component. In one embodiment (Fig. 7) a core component is fed into space 10 and thence via orifices 3 in back plate 6 to the narrow space 4, 5 between the backplate and orifice plate 7. A sheath component is fed from spaces 8, 9 to flow inwardly towards the orifices so that a sheath/core multifilament is extruded through orifices 1 in orifice plate 7. The eccentricity of the core within the sheath depends upon the distance between the plates, and the diameter and density of the orifices. The orifices may be arranged in a row or rows perpendicular to the direction of flow of the second (i.e. sheath) component, and may be further arranged so that a line joining an orifice in one row to an orifice in the adjacent row is not parallel to the direction of flow of the sheath component. A preferred spinneret has 4-50 rows of orifices when the number of rows is even, or 7-51 rows or orifices when the number of rows is odd. In Example 1, a 15% solution of acrylonitrile/ methyl acrylate copolymer in 70% nitric acid at - 3 C. is extruded into 33% nitric acid at - 3 C. and the coagulated filaments are waterwashed and hot-stretched 8 times. The resulting fibres are treated with oil, dried and treated with steam at 120 C. to generate crimps.

Title: Manufacture of beverages and the like
IPC: A23N1/02
Filed: 1964-01-15
Abstract: <PICT:0981211/C6-C7/1> In a process for the manufacture of a citrus fruit product comprising comminuting the fruit in bulk or limited bulk quantities in a plurality of comminuting devices, the fruit is directed to the comminuting devices by feeding it to a jigging conveyer having a plurality of guideways extending to respective comminuting devices, feeding of the fruit to the guideways being assisted by the jigging action. Oranges are discharged on to a shaker conveyer 23, Fig. 1, from the lower end of skips 10, Fig. 3, which are supported on a cammed (17) rocker shaft 16 actuated by a hydraulic motor 18. From the shaker conveyer the fruit is elevated by a conveyer 25 to a hopper 34 from which it is loaded into compartments of a Ferris wheel 38 upon withdrawal of a baffle 36 by a hydraulic motor 37. (An optional weighing <PICT:0981211/C6-C7/2> <PICT:0981211/C6-C7/3> mechanism is not shown.) During the anticlockwise rotation of the wheel the fruit passes through a bath of steam-heated water located in the lower part of the wheel and then falls down a shoot 50 into one of two jigging conveyers 51, 52, Fig. 2. The first section of each jigging conveyer at 53, 54 is smooth surfaced and this leads to four corrugated guides at 55, 56, for delivering the fruit through vertically-disposed guide tubes to the respective one of eight comminuting devices 63 of the form described in Specification 934,348. The liquid fruit product and solids resulting from the comminution are fed by screw conveyers 70, 71 to a collecting hopper 74 for separation as described and claimed in Specification 934,348. Operation of the hydraulic motor 37 may be regulated by cam pegs 83 and 84 on the Ferris wheel cooperating with cam followers 85 and 86. Means (unspecified) may be provided to prevent overfeed of fruit into the Ferris wheel.

IPC: B21B39/24
Filed: 1965-05-24
Abstract: One jaw M1 of a pair of tongs is moved into engagement with a reaction jaw M2 by a pneumatic ram housed in a cylinder 1 and connected to the jaw by links 16, 17, 19 and a hollow shaft 7.

The whole device is rotatable about an axis parallel to the axis of the shaft 7 and an axis perpendicular thereto. Opening and closing of the jaws is controlled by an electrically operated valve 37, Fig. 4 (not shown).

Title: Process and Apparatus for Multi-Stage Flash Evaporation.
IPC: C02F1/06
Filed: 1968-05-03
Abstract: In a multi-stage flash evaporator, e.g. for desalinating sea water, the vaporization of water in each of the flash chambers (except the first) is facilitated by introducing bubbles of vapour from the preceding chamber into the water as it enters the chamber, the vapour bubbles being introduced via a capillary tube 18 passing through the partition 15 separating the two successive chambers. The capillary tube may be replaced by a grid formed by a multiplicity of apertures. Prior to entering the first chamber, the sea water is degassed, preheated by heat-exchange with flashed vapours, and passed through an auxiliary heater, e.g. associated with a nuclear reactor. Vapour from the auxiliary heater may be used to facilitate vaporization of water in the first flash chamber.

Title: Brake-Releasing Mechanism
IPC: B60T17/08
Filed: 1968-06-01
Abstract: A pneumatic brake actuator 10 is provided with an auxiliary brake actuating mechanism 12 comprising a piston 38 normally held in the brakes off position by pressure in chamber A provided with a central sleeve 56 in which is threadably engaged a plug 66 having a hexagonal head 68 accessible from outside by removing a vent plug 68a. Normally, the brakes are actuated by supplying pressure through line 80 to displace diaphragm 18 and piston 30 against the action of spring 36. The auxiliary brake actuating mechanism is operated by releasing the pressure in chamber A so that spring 54 displaces piston 38 and hence push-rod 46 and piston 30 in the brakes on direction. To release the brakes, vent plug 68a is removed and a socket wrench (not shown) is inserted into sleeve 56 to engage the head 68 of plug 66 which is then turned to allow spring 36 to release the brakes.

Title: Refining apparatus, chiefly for screening paper pulp
IPC: D21D5/02
Filed: 1968-08-01
Abstract: A paper pulp-screening apparatus involving a cylindrical, perforate or slotted, metal screen 2 which is kept clean by one or more moving blades 1, which create pulsations on the upstream or downstream side of the screen, comprises elongated obstructions, consisting either of bars 5 or recesses in the screen surface adjacent the blades, which extend parallel or slightly obliquely to the blades across the screen.

Title: Process for the polymerization of olefins
IPC: C08F10/00

Abstract: Alumina-supported halogen-containing transition metal compounds prepared in such manner that (a) the transition metal compound is chemically bound to and supported by an activated alumina having a high surface area and an internal pore volume greater than 0.8 cc/g., (b) the concentration of the transition metal compound chemically bound to the support is greater than 10 grams of transition metal per kilogram of activated alumina, and (c) the atom ratio of halogen to transition metal on the support is higher than that of the halogen-containing transition metal compound which is used and preferably greater than 3:1, have been found to be unusually effective cocatalysts for the polymerization of ethylene and other alpha -olefins. These supported cocatalysts, which may be used to produce polyethylene as well as interpolymers of ethylene with other alpha -olefins and with diolefins, are prepared by heating an alumina hydrate (such as boehmite) to a temperature in the range from about 500 DEG C. to 900 DEG C. for a period of time sufficient to form an activated alumina having an internal pore volume greater than 0.8 cc/g., and then reacting the resultant activated alumina under substantially anhydrous conditions with a halogen-containing compound of a transition metal of Groups IV-A, V-A or VI-A of the Periodic Table. When ethylene is polymerized or copolymerized in the presence of a catalytic amount of the reaction product of an organometallic compound of a metal of Groups I-B, II-A, II-B, III-B or IV-B of the Periodic Table, and one of these supported cocatalysts, it is possible to produce normally solid, high molecular weight polyethylene or interpolymers of ethylene and other alpha -olefins at exceptionally high yields of polymer per gram of catalyst.
