Abstract: 1,050,825. Making heat exchangers; bending cutters. BORG-WARNER CORPORATION. Dec. 2, 1963 [Dec. 20, 1962], No. 47534/63. Headings B3A and B3W. [Also in Division F4] A stack of heat exchanger fins 7 is formed from strip material by a continuous process in which the strip is folded concertina fashion to form the stack, after having formed therein flanged tube apertures 8 and fin spacing lugs 10 (all formed by die presses 40, 41), and slots 30, 31 along the fold lines, these slots being formed by cutting knives 35, 36. The lugs 10 and tube aperture flanges of adjacent fins 7 in the unfolded strip extend from opposite faces of the strip so that when the strip is folded the said lugs and tube apertures all extend in the same direction in the stack (see, e.g. Fig. 12, not shown); and other apertures 43 with jagged upstanding edges, which in use are air turbilizers, may be formed between the tube apertures. The integral spacing lug 10 is formed from the strip material by the punch assembly shown in Fig. 6. This comprises a die plate 12 in which is a rectangular opening 14, a punch 18 and a stripper plate (not shown). The punch 18 has bifurcated cutting prongs 22 from each of which extends a sloping face A, and cutting edges D associated therewith and a further cutting edge 26 from which extends a sloping face 24. As the punch approaches the strip material 7 the latter is slit by the cutting edges 22 and further movement of the punch cuts the strip by means of the edges D and overturns the severed edges B. Finally the strip is slit along the edge C and the lug so formed is upturned at right angles to the strip by the angled face 24. A punch for forming two lugs similar to the lug 10 shown is described (Fig. 8, not shown). Alternative shapes of lug are shown in Figs. 14 to 16 but no dies for producing these shapes are described.

In a two-speed bicycle hub having a sun-ring planet train 15, 16, 18, ratio shift is automatically controlled by centrifugal governor weights 27a, 27b pivotally carried by the ring gear 15. As shown planets 18 on a carrier 19 mesh a fixed sun gear 16 and a ring gear 15 which is splined to a block 7 fast with a driving sprocket 10. For low ratio the planet carrier 19 drives a hub 2 through a ratchet clutch 20, 23. At a predetermined speed the weights 27a, 27b move radially outward against the bias of springs 36 to release the tail of a pawl 12 which is urged by a spring (14) into engagement with a ratchet 11 on the hub 2 for direct drive. When the speed falls below the predetermined speed downshift is prevented until a torque reversal occurs to bring the pawl 12 into a position in which it is held disengaged by the governor weights. The weights 27a, 27b are interconnected by links 30, 31 for movement in unison. The tension of the spring 36 may be adjusted to vary the speed at which ratio shift occurs. In Figs. 8 and 9 (not shown) one end of the spring 36 is connected to one arm of a bellcrank lever (39) pivoted on the block 7 whilst the other arm of the bellcrank abuts a screw (41) which can be turned from the exterior of the hub to adjust the tension of the spring 36. In Figs. 11-17 (not shown) the spring (137) is connected to one end of a lever (153) pivoted on the block (108) whilst the other end of the lever engages a recess (145) in a disc (146) which is rotatable from the exterior of the hub to adjust the tension of the spring (137).

Abstract: 1295348 Plasma generators LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCOS SA 18 Feb 1970 [31 March 1969] 7835/70 Heading H5H Plasma flame apparatus for heating large areas of a workpiece comprises an anode body assembly having a plurality of spaced nozzle anodes 2 therein and at least one cathode 3 located opposite each nozzle orifice so that in use a plurality of spaced plasma flames 13 issue from the anode body assembly. The anode body assembly shown comprises an elongated copper or silver multiple anode 1 provided with a plurality of water cooled nozzles 2 insulated by plates 8 from tungsten cathodes 3 carried in a common insulating plate 5. The multiple anode 1 is connected to one side of a D.C. supply 4 and the cathodes 3 are connected in parallel to the other side. In Figs. 5 and 6 (not shown) the anode body assembly has a plurality of nozzle anodes insulated from one another by insulating spacers, each anode being connected to a separate supply (Fig. 5, not shown) or a common supply through an individual adjustable impedance, Fig. 6 (not shown). The arrangement shown in Fig. 1 may have its cathodes connected through independently variable impedances to a common supply (Fig. 4, not shown) or to separate sources (Fig. 5, not shown). Argon or neon is the plasma forming gas. Ignition may be achieved by momentary contact between the cathode and anode by means of a high frequency spark generator to initiate several arcs simultaneously, or preferably by a low frequency spark generator connected between the anodes and cathodes in succession. Such apparatus may be used for heat treatment, spraying refactory materials, nitriding and annealing broad moving workpieces. In Fig. 7 (not shown), two plasma flame assemblies of the type described are inclined with respect to one another so that their emergent plasma flames impinge at the surface of a moving workpiece. A.C. is passed from one multiple anode to the other via the plasma flames. A multiapertured powder hopper is provided between the multiple anodes. For tack welding the various arcs are struck at determined time intervals. In Fig. 9 (not shown), moving strip is heated by plasma "curtains" from transversely extending axially spaced multiple plasma assemblies and by internal resistance heating due to current passed through the strip via the plasma "curtains" from an A.C. source. This can be used for sintering cold rolled metal powders. By altering the impedance of the plasma flame from each nozzle, variations in heat treatment may be obtained across the strip. In Figs. 10 and 11 (not shown) the multiple anode assembly is annular, and the nozzle orifices are axially directed and equi-angularly spaced. This arrangement may be used to uniformly heat a monocrystal pulled along the axis of the annular multiple anode. In Fig. 12 (not shown), an annular multiple anode has a plurality of radially inwardly directed nozzles which heat a moving rod or bar during zone melting. A plurality of plasma "curtains" may be used as radiant heat or light sources e.g. as flood lights.
