Abstract: 1,175,267. Artificial kidneys. BAXTER LABORATORIES, Inc. 16 Dec., 1966 [16 Dec., 1965; 14 June, 1966; 29 Sept., 1966], No. 56499/66. Heading A5R. [Also in Division Bl] A dialysis apparatus for use in an artificial kidney comprises a thin tubular dialysis membrane and a supporting band for the membrane, the band comprising a first set of parallel strands arranged on one side of and disposed at an angle to a second set of parallel strands. Four tubes 2a-2d of semipermeable membranous material are coiled together in the same plane about a hollow core 12. The tubes are separated by supporting bands 4a- 4d of fibreglass, plastics or metal which are coiled with the tubes about the core. The coils are enclosed within a casing 13 which has outlet members 10 with conical bores through which the outlet ends of the tubes pass. The outlet members are evenly spaced about the circumference of the casing. Similarly shaped and spaced inlet members 10 for the inlet ends 3 of the tubes are provided in the core. The tubes are connected in parallel between main inlet and outlet conduits connected to the patient. The bands 4a-4d each comprise two parallel edge-defining filaments around which strands (6 Figure 5) are wound at angles of 60 and 120 to the filaments to form a flat mesh structure. In use the strands (6) of the bands compress the tubes, which are of flat tubular form, to form interconnected pouches (7) and define flow channels for wash solution outside the membrane. The conical bores of the inlet and outlet members 10 secure elastic terminal tubes 9 in frictional sealing engagement with the inlet and outlet ends of the tubes.

Abstract: 1326990 Treating endless webs ARGELICH TERMES Y Ca 10 Dec 1971 [16 Dec 1970 19 June 1971] 57582/71 Heading D1L Apparatus for treating endless lengths of cloth in rope form comprises a tubular body of right-angled triangular shape 1 with rounded vertices and having its base section 2 longer than its vertical side, a pump 25 for circulating treatment liquid in the tubular body, a liquid heat exchanger 29 disposed between the pump and the treatment vessel, liquid inlet and outlet means to the treatment vessel, liquid jet means housed in a portion 4 of the treatment vessel for driving the endless cloth round the apparatus and a cylindrical chamber 5 forming an extension to the vertical side of the vessel for the introduction of the cloth to the apparatus. The liquid jet means is supplied with heated treatment liquid by pump 25 through conduit 51 (Fig. 2 not shown) and preferably comprises a braking jet 39 and a drawing jet 40 (Fig. 5) arranged to have a common external sleeve and operate in opposite directions, the forcing pressure of the liquid emitted by the drawing jet 40 being controlled by valves 51(a) (Fig. 2) to be greater than that emitted by the braking jet 39. Liquid entering the jets from conduits 51 passes through a series of orifices 41a in inner wall 41 to jet chambers 52 and exits these chambers through outlet orifices 58 to contact the travelling endless cloth passing through central chamber 53. The direction of travel of the cloth may be reversed by altering the relative forcing pressure of the liquids passing upwardly and downwardly from the jet means. The jet assembly is preferably removable from the housing 4 through chamber 5 so that jet assemblies having different diameters may be used depending on the characterics of the cloth to be treated. The apparatus preferably also includes frusto-conical tubular sections 8 and 10 joining the larger diameter portion of the treatment vessel to the jet housing 4 and a portion 3 of smaller diameter which opens into the upper chamber 5. The circulation speed of the cloth may be measured by a yardage counter driven by roller 38 mounted in the hypotenuse section of the apparatus and a by-pass conduit 23 with valve 24 may be provided to regulate the pressure of liquid between two sections of the vessel. An inclined guide ramp and suction device 15 are disposed below the jet housing 4 to cause the cloth to fold transversely so that it passes through the larger diameter sections of the vessel in a piled condition (Fig. 3, not shown).

Patent GB-616964-A (GB)
Abstract: 616,964. Grinding grooves. REISHAUER-WERKZEUGE AKT.-GES. Nov. 5, 1941, No. 14265. Convention date, Nov. 12, 1940. [Class 60] A grinding machine for thread grinding embodying means for producing closed circular grooves in cylindrical workpieces in which a ring cam having a lift corresponding to the desired groove spacing is provided on a line spindle movable axially by a lead screw and which co-operates with a follower connected to the workpiece in such manner that the latter is stationary in relation to the grinding tool in the axial direction during the production of a circular groove, is characterised in that the grinding tool can be brought into and out of the working position in the radial direction in relation to the workpiece for passing from one groove to the next, by means of a tool-control cam driven in dependence on the lead screw, and that, further, the ring cam is positively driven in the same direction as, but at a smaller speed than, the follower so that the grinding tool acts continuously on the workpiece for more than one complete revolution of the latter. A work-table F is moved longitudinally past a grinding-wheel S by a lead screw 15 driven through gearing from a shaft 1. A shaft 2 horizontally journalled in a base A and driven from the shaft 1 has keyed thereon a gear 3 meshing with a gear 4 journalled on a live spindle 5 in a headstock B. The gear 4 drives through a single tooth coupling a sleeve 6 keyed to the line spindle 5. The spindle 5 drives, through gearing and a sleeve 8, a second spindle 7, rotatably mounted in the spindle 5, which spindle 7 rotates a workpiece 12. A ring cam 11 attached to the spindle 5 is engaged by a follower 101 of a disc 10 attached to the spindle 7. The gearing between the spindles 5 and 7 is so arranged that the spindle 7 rotates at twice the speed of the spindle 5 and the resulting travel of the follower 101 on the ring cam 11 moves the work 12 relatively to the moving carrier F at an equal speed in the opposite direction so that the work remains stationary relatively to the grinding-wheel S until a steep part 111 of the cam is reached when the work is given a longitudinal indexing movement so that the next groove may be ground. During this longitudinal indexing movement, the grinding-wheel is automatically retracted from and then fed into the work. Means for doing this include a cam 25 driven from the shaft 1 through gearing, a rod 31, and a shaft 18. A pivoted follower 24 engaging the cam moves a piston 22, Fig. 4, and shaft 21 to move a grinding-wheel slide D away from or into the work. Liquid is supplied to a cylinder 23 in which the piston 22 moves at appropriate intervals by means of a grooved piston 59 carried by the shaft 18 and rotating in a cylinder 57.
