Title: Manufacture of tubes of synthetic resin having a perforated wall
IPC: B26F1/00
Filed: 1971-09-22
Abstract: 1359318 Perforating tubes E G W NORDSTROM 22 Sept 1971 [22 Sept 1970] 44224/71 Heading B5A [Also in Division F2] A perforated synthetic resin drainage tube is formed by severing from the tube projections which extend outwardly of the tube wall. The unperforated tube may be formed by extrusion, and may be cylindrical or have corrugations 4 from which the projections 5 extend, and may be fed either separately, or directly, from the extruder through guide tubes 2, 3 around each of which are rotated, on bearings 10, 11 and by means of belt pulleys 6, 7, members 8, 9 each carrying an inwardly projecting blade 14, 15 which sever the projection 5. The members 8, 9 rotate in opposite directions to balance the cutting forces dircumferentially of the tube, and these forces axially of the tube are also balanced by the oppositely directed inclinations of the cutting edges of the blades 14, 15. The downstream blade 15 severs the remainder of the projections cut by the blade 14, preferably leaving a collar of the projection extending from the tube wall. The corrugated tube may be fed to the severing device by one or more wheels having teeth drivingly engaging the corrugations. In the Fig. 5 embodiment, only one rotary member carrying a cutting blade is provided, rotation of the tube during severing being prevented by engagement of the projections 105 within grooves 120 extending longitudinally of the guide tube 102.

Documents such as cheques 9 are fed from a stack to printing mechanism 10 of an adding or accounting machine, adapted to print each document in a sequence of operations controlled by a programme control device comprising a support, shown as a drum 5, intermittently movable through a set of stations associated with the operations, each document fed actuating a pair of lugs 150 so as to cause a first cyclically operated mechanism, including a clutch 8, to move the support through said set of stations, the documents being fed by a second cyclically operated mechanism, including a clutch 59 and shaft 44, which is conditioned for operation by a shiftable member 86 controlled by the support when near the end of its cycle. Rotation of the shaft 44 causes further rollers 131 to be moved against the stack of cheques in a container (24) and feed the end cheque sideways, upwards in Fig. 2, similarly rotating rollers 117, 119 preventing double feed. Prior to sheet separation, a roller 106 moves the sheet downwards to align it with the container bottom, and a plate 26 is moved against the left side of the stack under the control of a crank arm 34 on a shaft 36 which is moved half a revolution at a time. The feed is initiated by a key (57) which controls a clutch 46 actuating the shaft 36, and a second operation of the key withdraws the plate and stops the feed by means of a pin 79 on the shaft 36 moving the member 86 to a position where it is ineffective to close a clutch 59 for the shaft 49. Each cheque is forwarded to feed rollers 11, 12 and thence against the lugs 150 and to printing position.

[Also in Division B1] Apparatus for oxygenating blood comprises a rotatable member having a large surface presenting a tortuous path over which the blood is spread in the form of a film, means for admitting fluid near the axis of rotation and means for withdrawing it near the periphery of the member. In the embodiment shown, three coaxial cylindrical members B1, B2, B3 are assembled as a unitary structure to rotate on ball-bearings on a stationary hollow shaft E. The inner surfaces of the members B1, B2, B3 are of slightly conical form so that blood, admitted through the tube E and passing out through apertures C1, under the influence of centrifugal force, travels along these inner surfaces in turn, following the labyrinthine path B, and finally passing through slots (not shown) into the chamber H, from the periphery of which it is received by a stationary scoop J and passed to an outlet tube L. At the same time oxygen is introduced through a tube C2 and follows the same path B, so that it is in continuous contact with the blood. In a modified form, see Figs. 5, 6 (not shown), the cylindrical surfaces are replaced by two interleaved spiral surfaces. Gauze filters may be inserted between the centrifuging and collecting parts of the apparatus.
