Abstract: 1,260,612. Making heat exchangers. OLIN CORP. 20 April, 1970 [9 June, 1969], No. 18679/70. Heading B3A. In a method of making a tube-in-strip heat exchanger formed from composite strip provided with an internal pattern of stop weld material, a tensile force is applied to the strip 6 whilst the tubular passages are expanded by fluid under pressure. The strip 6 is held by a clamp 20 and pulled by a grip 21 to produce a tensile force of 40-110 p.s.i. whilst water under pressure or air under pressure at 2000-2700 p.s.i. is supplied through a device 22 to expand the passageways. The composite strip is formed by hot-rolling after which it is annealed, cold-rolled and further annealed. Opposite sides of the composite may be of the same or different metals, e.g. Al, Cu. The heat exchanger may have marginal fins (14, 15), (Fig. 4, not shown), formed by slits or fluid-inflated passages.

Title: Manufacture of plastics foil tubes
IPC: B29C48/90
Filed: 1974-05-02
Abstract: 1463901 Flattening tubular films; extruded film DEMAG AG 2 May 1974 [2 May 1973] 19300/74 Headings B5A and B5B The tube of initially circular cross-section is passed through a support and guide unit which has a cross-sectional shape which, considered throughout its length, is appropriate to the desired shape of the plastics tube during its deformation, so that all points on the circumference of the tube are constrained to following paths of equal length during formation prior to passage through squeeze rolls. The guide 8 is a flexible tube which has such a shape that all lines drawn between the ends and defining paths to be followed by points on the foil tube (referred to as mantle lines) are of equal length. The adjustment devices 6 and 7 are operated to centre the guide elements 5, 4 and hence 8, and the devices 7 are displaced towards the annular nozzle from which the foil tube issues. The outside mantle lines are thereby tensioned while the other parts of the tube 8 hang more or less loosely between parts 5 and 4. Since the inside circumferences of 4 and 5 are identical the intake foil diameters and the required final size are obtained by adjusting 5. When a tube 3 is fed into the apparatus, 8 and the foil tube positively assume the shape in which all lines followed by points on the foil tube between 4 and 5 have the same length. The guide element 4 may be adjustable in the same way as in a camera iris and 5 may comprise two mutually adjustable parts to define a slot of variable length. Guide 8 may be formed of flexible bands or strips of equal length and a cooling device may be positioned between the two guide elements.

Title: Improvements in circuit-controlling devices
IPC: H01H13/02
Filed: 1936-07-08
Abstract: 467,764. Retractive switches and mechanical switches without quick action. EVANS, C. J., and EVANS, S. C. July 8, 1936, No. 19421/35. [Class 38 (v)] In a switch having an actuating plunger slidably mounted in a tubular element and carrying contact connecting means, a relatively fixed contact carrying element carries a plurality of contacts either directly or in portions of insulating or conducting material carried thereby, such contacts being furnished with means for adjusting their relative positions so as to vary at will the order in which they come into operation and the positions of the actuating plunger at which they come into operation. As shown in the Figure, the operating rod 6 slides within a tubular element 7 projecting from the side of a cylindrical casing 10 of insulating material. Projecting inwardly from the end and/or side of this casing are a series of relatively fixed spring plunger contacts each mounted within an externally-threaded casing 17 and provided with a lock-nut 20 so that the position of each contact is adjustable in relation to the casing. Mounted on the operating rod is an insulated bridging member adapted to co-operate with the relatively-fixed spring plunger contacts, the bridging member being formed with a flat end surface 22 and a side or peripheral surface 23 which is inclined or tapered. The operating rod may be acted upon by a spring 21 to retract it to the outer position with an oppositely-acting spring or, alternatively, no spring may be furnished, the switch being capable of being moved in one or other of two directions from a central position. At the outer ends of the plunger casings are transverse holes through which leads may be passed and held in position by clips 18 acted upon by the springs 19. The adjustment provided by the screwing in and out of the spring plunger casings determines in the case of the plungers 11, 12 the order in which they engage the end surface 22 of the movable contact and also the point in the path of the moving contact at which each individual plunger engages such surface. Similarly, adjustment of the lateral contacts 15, 17 determines the order and position in which they engage the inclined lateral surface 23. One or more of the plunger contacts may be adjusted to remain in engagement with the movable contact during the whole of its range of movement. The plungers may be arranged at an angle to the switch axis.

Abstract: 426,690. Variable resistances. CENTRAL RADIO LABORATORIES, 900, East Keefe Avenue, Milwaukee, Wisconsin, U.S.A. July 2, 1934, No. 19480. Convention date, July 7, 1933. [Class 37] A resistor 5, which may be wire wound or a cardboard, paper, or other flexible strip coated with carbon &c. on its inner face, is clamped against the inner face of the wall of a cylindrical housing 2 of insulating material by means of an expansible washer 15 of insulating material, which also clamps bent-up lugs 13 of terminals 7, 8 against the ends of the resistor. The washer 15 carries a contact member 20 formed with a flange 20<1> with which engages the inwardly curved lower edge of a flexible metal contacting ring 26. On a shaft 33, which is rotatable by a knob (not shown), is fixed a radial arm 32 carrying a spring arm 31, at the end of which is a pressure pad or button 30. This engages the flexible strip 26 so that it is deformed radially into contact with the resistor 5. The shaft 33 is rotatably mounted in a bushing 35 which is externally threaded to take a nut 40 and has a tapered portion 41. This expands the washer 15 by engaging portions 18, the washer being split at 17. A plate 37 is formed with a stop finger 38 and is held in place by engagement with a shoulder 36 on the bushing 35. Lugs 37<1> on the plate 37 engage the shoulder 36 and a recess 3<1> in the housing, thereby locating the stop finger 38 and preventing rotation of the bushing. A cover 4 has an aperture 4<a> through which the finger 38 is passed and bent over to secure the cover. A terminal 22 is connected to the contact member 20 by means of a rivet 21. In a modification, the member 20 is omitted, the ends of the flexible member 26 being riveted to an upstanding lug on the terminal 22, and the button 30 slides in a recess in a ring and is spring-pressed outwardly. In another construction the resistor, flexible contact member, and the peripheral wall of the housing are conical.

Title: Improvements in or relating to hydraulic systems for actuating brakes
IPC: B60T11/10
Filed: 1945-07-30
Abstract: 596,494. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. July 30, 1945, No. 19522. Convention date, Aug. 30, 1944. [Class 103 (i)] A hydraulic master cylinder system for operating aircraft and other brakes comprises a valve which when the brake is to be applied for parking is permitted to act as a non-return valve to enable the brake to be applied by repeated strokes of the master piston liquid being also forced into an expansible chamber which communicates with the pipe lines and serves to compensate for leakage losses and changes of volume of the liquid. For normal braking the valve is put out of action as a non-return valve and then acts to cut off the expansible chamber. A valve 50 arranged in a chamber 34 connected by passage 36 to the brakes is normally held as shown against a seat on the left-hand wall of the chamber by a cam 60 acted on by a spring 64 so that the brakes can be applied by a single stroke of the piston 14 of the master cvlinder 12 operated by the rod 16, the liquid being forced from the master cylinder through passage 31, cam chamber 32, passage 33 and chamber 34 to the brakes. To condition the system for parking, the cam 60 is moved downwards by a rod 66, lever 68 and cable 69 to allow the valve 50 to seat on the right-hand wall of the chamber 34 so that a chamber 38 containing a piston 40 loaded by a spring 42 is connected by passage 46, chamber 48, the valve 50, chamber 34, and thus to the brakes. The brakes may then be applied by repeated strokes of the piston 14 part of the liquid being forced into the chamber 38 and the valve 50 acting as a check valve at each stroke to lock the liquid in the chamber 38, the chamber 34 and the brakes. When pressure has been built-up in the system the tension in the cable can be relaxed, the back-pressure on the valve acting to hold the cam in the lower position. To release the brakes, the piston 14 is first actuated to build up pressure in chamber 32 to counteract the pressure in the brake lines thus permitting the spring 64 to return the rod 66, this action being assisted by the fluid pressure acting on the piston area of the rod 66. The valve 50 is thus moved to the left to permit the liquid to return from the brakes and the chamber 38 to the master cylinder and the reservoir 22 when the piston 14 is returned. The piston rod 16 carries a valve 18 which seats on the piston 14 during the downstroke but which is unseated during the return stroke to permit liquid to flow to the master cylinder from the reservoir 22.
