Abstract: 1449296 Making heat exchangers; welding by fusion; welding by pressure; soldering BRITISH LEYLAND UK Ltd 31 Jan 1975 [31 Jan 1974] 04469/74 Headings B3A and B3R A method of producing a heat exchanger matrix of packed construction type having tubes and fins arranged in alternate layers comprises assembling a stack of unconnected alternate tube and fin elements at a first station, advancing the stack to a second station fixing the elements at the second station in successive uniform sections, and separating each section from the stack as it leaves the second station. The elements can be fixed in clamps at the second station and then transferred to an oven for baking. Alternatively, the elements may be heated at the second station to effect bonding or welding together of sections of the stack. The tubes or fins may be coated with a hot-curing adhesive material, e.g. an epoxy resin, or coated with solder and flux. Separation of individual stack sections is made by providing uncoated dummy elements, or alternatively interrupting the application of heat using a refractory shutter. Other welding techniques may be used for fixing, e.g. plasma arc or ultrasonic welding. In an embodiment, a hopper 1, Fig. 1, is charged with fins and magazines 4, 4a., Fig. 5, are charged with tubes. An infra-red heater assembly 16 is switched on and stacking commences when the soldering temperature is reached. The fins are pneumatically fed lengthwise along a passage 2. A pneumatically controlled gate 3 determines the delivery intervals. The tubes are fed transversely of their length along a split delivery table 5 by delivery blades 6, 6a. A plunger bar 8 is movable by a pneumatic actuator 9 to push the assembled stack through a pair of planishing rollers 11, 11a. A pair of pinch rollers (12), 12a, Fig. 3 (not shown), coupled to an electric motor 13, grip the stack and a further pair (14), 14a are provided with an adjustable brake 15. The drive afforded by the motor through roller 12a is balanced by the braking through roller 14a so that the stack is under constant compression. The fin delivery includes a duct containing gas jet openings. Further compressed gas openings are arranged in the opening of the split table 5 for stretching corrugated fin elements to a uniform length.

Addition to 338,436, [Class 83 (iii), Metals, Cutting]. [Class 83 (iii).] Milling-cutters.-The method of hobbing bevel gears described in the parent Specification, wherein a rotary cutter having straight-sided teeth arranged along part of a single turn of a helix is employed to generate the tooth profiles on the blank, is adapted to the production of gears having inclined teeth or to hyperbolic gears. Thus in Fig. 1, if, for the cutting of straight gears, the cutter moves along the vertical line YV and represents a crown wheel having inner and outer circles R, S, respectively then, if the cutter is displaced so that it describes the path O<1>M it will trace out a wheel having inclined teeth such as DB. The complete generation of a tooth having the generatrix DB will require angular movements of the cutter slides over the arc AK and in order to reduce this to the normal arc AC the cutter slides are inclined so that the cutter starts cutting at the point Y and remains (in the mid-position of the generating swing) in the vertical line YV while generating a tooth represented by the line Y<1>V tangential to the circle having the radius OO<1>. For this purpose the reversal of the movement of the worm 3 actuating the generating movement of the tool head is controlled, through reversing bevel gearing 20, by a lever 17 actuated by an abutment 14 coacting with adjustable projections 12 on a screw 13. The abutment 14 is carried on an arcuate segment 15 slidable in a guide in the slides 1. The segment is slotted at 21, and a pin carried by an arm 25 on the tool slide engages in the slot. Thus at the commencement of the operation, the slides are in the position shown in Fig. 3 and at the end of the operation the Fig 5. position is reached, the cutter tracing out the tooth generatrix Y<1>V and the segment 15 sliding in its guides so as to maintain the abutment 14 in the vertical line passing through the point O. By adjusting the relative positions of the cutter and blank the invention may be applied to the production of hyperbolic gears.
