Title: Improvements in or relating to the production of gilled or finned tubing for heat exchangers
IPC: B21C37/24
Filed: 1957-02-01
Abstract: 835,136. Making radiators; corrugating; perforating. WITHNELL, B. F. April 22, 1958 [Feb. 1, 1957], No. 3500/57. Classes 83 (2) and 83 (4). [Also in Group XIII] A method of making gilled tubing for use in heat exchangers comprises corrugating a length of metal strip and forcing a tube through the substantially plane portions of the strip between the corrugations such that the tube pierces said plane portions approximately along the central longitudinal axis of the corrugated strip and produces in the plane, portions marginal flanges which abut against the tube wall. In an apparatus shown in Fig. 1, for making the gilled tubes, and carried on a bed-plate 10, the leading end of a copper, aluminium, brass, copper-coated aluminium or like metal strip 49, is secured at 56 to a movable comb-like former 21 above which is positioned a vertically reciprocating platen 11 carrying a corrugationforming die 14 and a locator plate 16 vertically movable with respect to the platen against the action of springs 19. Successive corrugations are formed in the strip 49 by progressive movements of the former 21 along the bed 10 as the die is reciprocated. These movements are imparted by corresponding movements of a carriage 20 which abuts the former 21 and are effected by means of a reciprocating gripper feed mechanism comprising a feed-plate 25, thrust block 40 and two feed clamps 36 the gripper feed mechanism being coupled to the platen 11 by a lost-motion connection comprising a pivot pin 29 on the platen, a link 27 and collars 31 on the link which engage the pin 29 in turn as the platen reciprocates. A braking force is applied to the carriage 20 by wooden brake members 42, 43 biased towards one another by springs 44. As the former 21 is progressed the corrugated strip carried thereby is eventually pierced by a sharpened tip 58 provided at the end of a pipe or conduit 55 the latter then passing through the pierced portions of the corrugated strip to form the gilled tube shown in Fig. 5. The resulting flanged portions 60 (Fig. 5), formed around the apertures pierced in the corrugated strip may be soldered or resin bonded to the tube 55. The strip or the tube may be embossed or dimpled to increase the heat transfer surface area.

Abstract: 1,128,331. Boundary layer control. HANDLEY PAGE Ltd., J. B. EDWARDS, and A. A. BLYTHE. 27 Jan., 1966 [27 Jan., 1965], No. 3638/65. Heading F2R. [Also in Division B7] A surface to which boundary layer suction is applied, for example an aircraft wing or fuselage skin 1 has an elongate slot 6, undercut surfaces 11 within the slot and an elongate element 12 (e.g. of aluminium or nylon) disposed within the slot. The element has an outer surface 14 shaped to complete the outer contour of the skin and its edges are spaced from the adjacent edges of the slot to form slits 2 to which suction is applied through apertures 9. One or both walls of each slit may be inclined, for example at 3-5 degrees to the normal to the surfaces 14 15 so that the slit tapers, as shown, and one edge of the slit may be raised relative to the other, for example by the width of the slot (e.g. 0.005 inch), to stabilize the boundary layer flow. The undercut surfaces 11 may be formed as shown in portions 17 upstanding from the base of the slot and be engaged by legs 18 of the element 12 extending between the portions 17. The element may be pliable to snap in place, or may be deformed by running a tool through the space 20. It may also be held by adhesive, bolts or rivets. The upstanding portions 17 may be integral with the skin, as shown, or formed by a separate channel section member secured in the face of the slot (Fig. 2, not shown). Alternatively (Fig. 3, not shown) a single upstanding portion is used with undercut surfaces on opposite sides, or the undercut surfaces may be in the side walls of the slot (Fig. 4, not shown). The element may be formed by short lengths placed side by side, which may then be dropped into a space at the end of a slot where the upstanding portion is omitted, and slid over the end of the upstanding portion (Fig. 5, not shown).

Abstract: 738,482. Electron beam apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 13, 1950 [Feb. 12, 1949], No. 3644/50. Class 39 (1). In a tube of the kind in which a number of space " electrodes S1 ... S8 are arranged around a central cathode 12 and a magnetic field is applied parallel to the cathode so that, upon the potential of a space being lowered the electrons follow trochoidal paths to the region of that space, the " box between adjacent spaces, S1 and S2 for example, contains at least two " catching " electrodes U1, V1, one of which, U1, is connected to the space S8 next following in the direction of electron/motion.; the other, VI, is preferably connected to catching electrode U8 next following and thus also to second following space S7 so that, in the embodiment shown, electrodes S1, U2, V3; S2, U3, V4, &c. are connected. The arrangement is said to reduce stray electrons because it suppresses electron emission over a large part of the cathode from which the electron paths would be of excessive length; and it enables a weaker magnetic field to be used so that the paths need not be complete trochoids. Each box may contain other electrodes m and each set of electrodes has separate series impedances Zs, Zu, Zv, Zm as well as common impedance Z and starting switch 26. The spades may be inclined either in the direction of electron movement or in the reverse direction and the front parts may be provided with grids, recesses, apertures or projecting fingers, Figs. 3 (not shown), to smooth out the spade-cathode field and modify its penetration into the boxes. If the magnetic field lines are not parallel the cathode or spades may be varied in cross-section so that their separation varies at different points along the axis to conform with the field. Specifications 653,878 and 675,465 are referred to.
