Inventor: MAUGHAN JOSEPH
IPC: G21C3/08
Filed: 1959-02-13
Abstract: 904,140. Heat-exchange elements. PARSON & CO. Ltd., C. A. March 23, 1960 [Feb. 13, 1959], No. 5034/59. Class 64 (3). [Also in Group XL (a)] In a heat transfer arrangement comprising fins or corrugations 1 forming flow channels and set at an angle to the main direction (X) of fluid flow over a heat transfer surface and wherein baffles 2 are provided to redirect fluid flowing in said channels into like channels downstream of the first channels, part of the fluid flowing over the tips of the fins or corrugations is impeded at intervals by other baffles or deflectors extending at an angle to the main direction of fluid flow over the surface. These latter baffles may, as shown, comprise outward extensions of certain fins or corrugations la or they may comprise elements bridging adjacent baffles 2, each in alignment with a fin 1. Although shown as applied to a tubular heat-exchanger or nuclear fuel element of the kind described in Specification 847,214, the invention is said to be applicable to non-tubular elements such as in plate-type heat-exchangers.

Title: Improvements in or relating to electric welding apparatus
IPC: B23K9/032
Filed: 1953-02-23
Abstract: 759,488. Welding by fusion. BRIGGS MOTOR BODIES, Ltd., and RUSSELL, F. April 12, 1954 [Feb. 23, 1953], No. 5058/53. Class 83 (4). Gas-shielded arc welding apparatus in which the electrode is traversed over the seam to be welded has means for holding a fusible wire in position along the seam. In a machine for welding contoured seams of e.g. an exhaust nozzle 22, Fig. 3, the welding head 20 is mounted on a carriage 17 running on rails 18. The filler wire 23 is tack-welded to the seam and is held in position by grooved hard-copper rollers 21 on spring-loaded levers pivotally secured to the welding head 20. A plate 24 carrying the welding head 20 is slidably mounted on a curved sector 25 parallel to the seam and the'sector 25 is supported on a plate 26 slidably mounted on a curved sector 27 perpendicular to the seam. The sector 27 is vertically hinged to a lever 28 horizontally hinged to a bracket 29 on the carriage 17. Thus the welding head is free to move laterally under the guidance of the rollers 21 but its other movements are automatically effected as the carriage 17 is traversed by cam slots 31, 41, 36 engaging the ends of levers 28, 39, 34 which respectively control the height of the welding head 20 and the movement of the plates 24, 26 relatively to the sectors 25, 27. When starting the weld, the arc is struck between the electrode 19a and the end of the fusible wire which is arranged to project beyond the seam. In a modification a single roller 6, Fig. 1, running on the fusible wire in front of the electrode 1 is carried by a spring-loaded lever 5 pivoted to a support 4 secured to the welding head or running on the same guide rails as the welding head.

Patent GB-661905-A (GB)
Title: Devices for wave guides employing ovalised sections
IPC: H01P1/165
Filed: 1949-02-28
Abstract: 661,905. Wave-guides. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Feb. 28, 1949 [April 26, 1948], No. 5350/49. Class 40 (viii). A pair of wave-guides 1, 2, and 5, 6 of circular cross-section are interconnected by a portion 3, 4 of oval cross-section. Portions 2, 3, and 4, 5 are shaped to effect a smooth transformation between the circular and oval crosssections. When the length of the oval portion is chosen relative to the working wavelength and the diameters of the oval cross-section according to given formulµ, the plane of polarization of an E 1 n, or H 1 n wave entering at 1, 2 is rotated through such an angle that in its near position, it is symmetrical with the original plane of polarization relative to a diameter of the oval section. Thus, by rotating the oval portion through 90 degrees the plane of polarization can be rotated through any angle up to 180 degrees. To get the right value for the oval portion according to the working wavelength, either the ovalization of the guide may be varied by a compression device as in Fig. 5, or the length of the oval portion may be varied by means of telescopic portions as in Fig. 4. Fig. 6 shows an arrangement for transmitting an H, wave from a circular guide G<SP>1</SP> into a guide G<SP>2</SP> which is not co-linear. The H, wave first passes a bend C<SP>1</SP> the angle of which is chosen as set out in Specification 657,450, so as to convert the wave into an E 1  wave polarized in the plane of the drawing. This wave then enters an oval portion O<SP>1</SP> made of a length according to the present invention, and oriented so as to rotate the plane of polarization through 90 degrees. This wave will pass through a bend C<SP>2</SP> without change. A second oval portion O<SP>2</SP> then rotates the plane of polarization through another 90 degrees, and a final bend C<SP>3</SP> converts this E 1  wave into an H 0  wave in guide G<SP>2</SP>. S-shaped portions of guide may be interpolated where the input and output guides are in different planes.

Title: Improvements in Machines for Automatically Binding Straw Cases.
Inventor: DIKS PETRUS MARTINUS
IPC: B65B21/24
Filed: 1917-04-19
Abstract: 106,481. Diks, P. M., and Heuvel, M., van den. May 17, 1916, [Convention date]. Covers.-In a machine for binding the heads of straw casings for bottles &c., the binding-thread or wire 1 is passed across the casing on a diameter a, Fig. 5, wrapped one and a half times, or in some cases two and a half, three and a half &c. times, round the casing, again passed across the casing on the diameter a and then stretched and cut off. In the machine shown, the casings 15 are supported by a flanged drum 12 and a toothed wheel 10 on a shaft 4, a guide 22 and a pair of toothed wheels 20 on a shaft 19 being provided for pressing the heads of the casing into the inter-tooth spaces of the wheel 10. The shaft 4 is rotated intermittently to bring a fresh casing into position by a pawl 50which engages a ratchet-wheel 49 and is operated by an eccentric 51 on a shaft 6. The thread passes through u a guide 23 on a slide 26 mounted on a plate 25 which is reciprocated vertically by an eccentric 29 on a shaft and horizontally by an eccentric 37 on a shaft 30. The slide " 26" is normally coupled to the plate 25 by a spring 41 holding a lug 42 on the slide in engagement with the plate. Vertical movement of the slide is periodically prevented by a sector 45 which is secured to the shaft 6 and can be swung under a lug 43 .on the slide. The shafts 5, 30 are driven at the same speed by a chain 34, and the shaft 6 is driven by a chain 48 from the shaft 5. The parts are timed so that the guide 27 describes the circumference of a circle h, g, f, i, Fig. 3, one and a half times or in some cases two and a half &c. times, and then moves horizontally across the diameter f, h, the circular movement causing the thread to be wound round the casing and the horizontal movement carrying the thread through the casing. Simultaneously with the horizontal movement of the guide, the casings are moved in the opposite direction bv the feed-device 49, the thread being thus passed for the second time through the casing I, Fig. 5, in position and for the First time through the oncoming casing II. The thread is stretched and cut by means of a reciprocating knife 54 which can enter openings in the wheel 10, the thread between two wrapped casings being pressed into the associated opening and then cut. The knife is secured to a lever 56 which is pivoted at 55 and formed with an incline 58 for engaging a roller 59 on a crank 66. Before the binding operation, the casings are cut to length by a knife 62 connected by a rod 65 to the crank 66. The thread-guide 23 is secured to the slide 26 by a screw 24 and is formed with a coned outlet. The thread passes through a tension-member consisting of two disks 68 which are mounted on a spring- tensioned bell-crank 70 and are pressed together by a spring 71.

Title: Production of metallic surface layers
IPC: C23C14/26
Filed: 1937-02-26
Abstract: Surface layers of the metals of the platinum group, e.g rhodium, are produced by heating, in a vacuum of at least 10-3 mm., e.g. 10-4 of mercury, the metals in the form of structures, e.g. strips, of large surface area per unit volume, and the subliming metal is condensed on work materials arranged in the vicinity of these strips &c.  The work which may be of glass, quartz, ceramic materials, minerals such as asbestos, or inorganic or organic substances is cleaned before treatment, and the metal is clamped at the two narrow edges in copper jaws and heated to a temperature below the melting point by direct electrical heating. The surface area of the strip &c. may be equal to or smaller or larger than that of the work; if smaller a uniform coating is ensured by moving, e.g. rotating, the strip &c. or the work.  The resulting surface is consolidated by an after treatment such as rubbing with polishing leather or cotton wool impregnated with lubricant.  The process may be used to produce weatherproof mirrors, surface layers which are partly permeable to light, condensers, or resistances of high-loading capacity.
