Filed: 1933-12-27
Abstract: In a vacuum pan particularly for concentrating sugar syrups comprising a shell A and a steam belt B having a central down comer G and pipes D<3> for the circulation of the syrup, this circulation is maintained constant for different heights of the syrup in the pan by providing a series of spaced conduits G<1>, G<2>, G<3> located in alignment above the downcomer G and each containing a screw propeller O<1>, O<2>, O<3> mounted on a shaft L which also carries the propeller O in the downcomer G.  Vanes J of truncated V-shape are located in the spaces between the conduits to check rotative <PICT:0410052/III/1> movement of the liquid in its passage between the conduits, which with the vanes are supported on angle irons I.

Title: A superconductive generator
IPC: H01F6/00
Filed: 1966-08-19
Abstract: 1,147,688. Superconductor devices. SIEMENS-SCHUCKERTWERKE A.G. 19 Aug., 1966 [21 Aug., 1965], No. 37389/66. Heading H1K. In a superconductive generator in which a non-superconducting region traversed by magnetic flux of greater than critical strength moves through a superconductor lamina to induce a current therein, a superconducting return conductor is provided near the lamina, carrying opposing current to counteract the disturbing effects of the induced current on the initiating magnetic field. Fig. 2 shows a plurality of niobium-zirconium wires connected at one end to the top region of a niobium sheet 21. A magnetic field is caused to traverse the sheet and wires to produce a travelling non-superconductive region in the sheet but not in the wires, since the latter are made of higher critical field material. The travelling field induces a current output in leads 23, 24 connected to the opposite ends of the sheet and the wires, which is applied to a superconductor coil or other load. In alternative embodiments, the indium-zirconium wires are replaced by a niobium-zirconium sheet (Fig. 1, not shown) or by strips inlet into the sheet of lower critical field material and insulated therefrom except at one end. In another embodiment (Fig. 4A) the lamina is constituted by a niobium cylinder 41 which is traversed by a magnetic field between rotatable soft iron plate 42 and the inner surface of soft iron cylinder 44; the cylinder 44 is provided with slots 46 which enclose niobium strips 47 arranged as the return conductors. The magnetic circuit is such that strips 47 are subjected to a lower magnetic field than the appropriate portion of cylinder 41 so that 47 can be made of the same material as 41 and yet remain superconducting while the portion of 41 goes non- superconductive. Slots can be provided in cylinder 41 to avoid undersized eddy current. The hard superconductor could alternatively consist of niobium tin and the soft of lead.

After the point of entry 49 of the packages the rails 29, 30 are raised slightly so that the top of the chamber is closed by contact with a disc 35, the fourth side of the chamber being closed by a circumferential wall 37. Valves 40 in the disc 35 are connected through conduits 41 to a vacuum source and are opened and closed by the passage of the leading wall 26 and the trailing wall 27 respectively below them. Evacuation takes place in several stages, the vent 19 being finally sealed by means of welding electrodes. Packages are ejected at 46. Specifications 888,621, 888,622 and 888,623 are referred to.

Abstract: 1,106,416. Feeding webs. MOUNT HOPE MACHINERY Ltd. 22 Aug., 1966, No. 37467/66. Heading B6B. [Also in Division F2] Relates to web-tensioning apparatus comprising three triangularly arranged rolls (10), 12, 14, Fig. 2 and Fig. 3 (not shown), and disc brakes 30 each arranged coaxially with and acting to brake one of the rolls, wherein a single brake-applying member, constituted by a diaphragm 36 acted on by pressure fluid admitted to a chamber 46, acts on the centre (P), (Fig. 1, not shown) of a plate 34, or alternatively at another point within the triangle defined by the axis of brake-actuating buttons 32 of the respective brakes, such that desired proportions of the applied force, e.g. equal proportions, act on the respective brakes. The buttons 32 are coaxial with the roll shafts 22 each of which carries an air-cooled disc 68, Fig. 10, flexibly mounted via an elastic bush 146, or, alternatively, a flexible disc 68, Fig. 5, acting in each case between two rotationally fixed discs 60, 62, of which the latter is carried by a fixed framework and the former, which is provided with the respective button 32, is mounted by a number of peripherally spaced axially extensible support means. On operation of the brakeapplying member, disc 60 is moved axially to cause the disc 68, which is axially slidable on the roll shaft 22 by a splined connection 76, to be gripped between disc 60 and 62. The elastic bush 146, or the flexible disc 68 together with self-aligning ball bearing 24, allows the associated shaft 22 to whip, while the axially extensible support means for the movable disc 60 allows the latter to cant with respect to the brake axis so as to conform with the resulting deflection of the adjacent braking surface of the disc 68. The axially extensible support means comprise either U-shaped leaf springs 84, Fig. 5, which are bolted to discs 60 and 62, or, alternatively, roller and track guiding means comprising guides 124, 128, Fig. 10, having co-operating V-grooves to accommodate balls 122, the former guides being secured to disc 62 and the latter guides to disc 60. In the latter construction separate release springs 138 are provided. The discs 60, 62 are integral with drum-like members provided with cooling fins 78. Additional cooling may be provided by using the disc 68 of Fig. 10, which is formed by a pair of discs 112 between which are secured fan blades 110, apertures in the three discs being provided to enable air to flow radially outwards through the disc 68.

Abstract: 1,167,434. Centrifugal separators. H. P. O. UNGER. 16 Aug., 1967 [22 Aug., 1966], No. 37710/67. Heading B2P. A centrifuge for treating liquid and/or solid materials, e.g. for washing blood cells with saline to remove surplus albumin and for resuspending the cells, comprises a rotatable head 10, Fig. 1, e.g. of moulded plastics, holding containers 15, 15' for material to be treated, a liquid distributor 12 tiltable, Fig. 2, and vertically displaceable with respect to the head 10 and from which equal amounts of liquid can be. introduced into the containers via tubes or hoses 14, 14'. As shown in Fig. 1, liquid is fed to the distributor 12 through a connected pipe 13 tiltable and vertically displaceable in a nylon bearing 13' e.g. manually by means of a lever 32 which also controls a plunger 33 of a valve so that liquid is supplied to the distributor in its central, lower position. The distributor 12 and the pipe 13 are automatically displaced upwardly at the end of a centrifuging operation by a coil spring 34. A control device for fully automatic operation is shown at 35-38. In the tilted position Fig. 2, the hoses 14, 14' perform agitating movements in the containers to bring about re-suspension of particles previously separated out by centrifugal force in the containers. Small amounts of liquid can, alternatively, be supplied to the distributor during agitation. In the vertical raised position of the distributor, the hoses 14, 14' are clear of the bottom of the containers so that they can easily be removed and replaced as required. In Fig. 5, the distributor is tilted by a rod 18 held by means of a rubber plate 19 secured to the centrifuge head, the liquid being supplied to the distributor from above through a pipe 20. In another construction. Fig. 6 (not shown) liquid is supplied to the distributor from above centrally on to a rotating spreader plate. In Fig. 7, the liquid is supplied through a pipe 25, the bottom of the distributor acting as a spreader; alternatively, the pipe 25 may be bent at its lower end so that as the distributor rotates, the outlet sections 26.26' thereof receive equal amounts of liquid. In this case, a large liquid outlet pipe 28 is provided to release under a short period of time, larger amounts of liquid rapidly supplied in the form of liquid pulses to the containers to bring about re-suspension. Fig. 10 shows a centrifuge for sterile washing. Liquid is supplied from tanks 40, 41 under the control of a solenoid valve 42 to a sterile assembly 43 displaceable in a cover 52 and thence to a rotary distributor 44. Liquid leaves the containers through tubes 47, 47' and is fed to a waste conduit 48. The shaft 44' is tiltable by means of a solenoid actuator 48. A device 51 automatically controls the operation of the centrifuge drive 53.
