Title: Improvements in tunnel kilns
IPC: F27B9/02
Filed: 1934-02-22
Abstract: 435,452. Tunnel kilns. MOORE, B. J., Parkfield House, Princes Road, Hartshill, Stoke-on-Trent. Feb. 22, 1934, Nos. 5813 and 6431. [Class 51 (ii)] A tunnel kiln more particularly adapted for the manufacture of pottery comprises three or more side by side tunnels through which the goods are moved in opposite directions. In the three track kiln shown the goods on the middle track move in the opposite direction to those on the outer tracks, and at the ingoing end are heated on both sides from the outgoing goods. Heat interchange at the ends is promoted by the use of pillars 27 or chequer work instead of solid walls, such as 13. All the tunnels may be heated to the same temperature, or different temperatures may be maintained, e.g. for glost and biscuit firing, or for glost firing and hardening-on. The two outer tunnels for biscuit firing may be kept at a higher temperature than the middle " glost " tunnel or alternatively, when the glost firing is effected in two stages, the middle tunnel may be worked at high temperature for biscuit firing. As shown the outer tunnels have combustion flues 15 on their outer walls, and there are resistance elements 17 on both sides of the inner walls. The middle tunnel, when used for low temperature work, may be heated only by conduction from the outer tunnels.

Abstract: 1,127,772. Lamp caps and holders. ROWLANDS ELECTRICAL ACCESSORIES Ltd. 31 Jan., 1966 [11 Feb., 1965], No. 5896/65. Heading H2E. Heat dissipation from each end of a quartz iodine or other tubular lamp 16 is facilitated by a liquid contained between an insulating sleeve 43a, which houses the lampholder contacts, and an outer metal chamber. Each chamber comprises two parts 29, 30 secured together by screws 70 and a sealing ring 38, the upper part 29 being integral with a casing 10a, which is preferably of an aluminium alloy and may be clamped to a support. Each sleeve 43a, which is of ceramic material or of plastics material formed with fins, is retained in the apertured inner surface of each chamber by a flange 44 and a sealing ring, and houses a spring-loaded contact block (52, Figs. 5a-d, not shown), preferably of a copper-cadmium alloy, maintained in thermal contact with it by a split cylinder (58) and having a recessed end (53) for receiving a contact disc embedded in porcelain which surrounds the end of the lamp envelope 16. A terminal screw (61) passes through the block (52), its ends being located in grooves formed in sector-shaped projections (47) on the sleeve and the forward end engaging the groove (49) in a bayonet manner. In a modification (Figs. 6a-d, not shown), the contact block is retained by a spring (83) which is a tight fit in the sleeve (73) and over a projection (81) of the block.

Title: Improvements in electric welding apparatus
IPC: H05B7/02
Filed: 1957-02-21
Abstract: 818,733. Arc welding systems. UNITOR A. S. Feb. 21, 1957 [Feb. 21, 1956], No. 5903/57. Class 38 (4). In an arc welding apparatus wherein a set of resistors are connected in series with the electrodes to automatically adjust the welding transformer secondary current between predetermined limits, a central transformer is arranged to supply a bridge circuit connected to two relays giving adjustment in two directions. A welding transformer 1, Fig. 1, supplies electrodes 2, 3 through the primary of central transformer 4, the secondary of which is connected through a rectifier 5, to bridge network 6, Fig. 1, comprising linear and non-linear resistors 61, 62. The voltage output from the bridge network operates valves 73, 74. With resistor 81. connected in circuit, valve 73 operates relay 75, reducing the secondary current of transformer 1, whereas with resistor 82 connected, valve 74 operates relay 76 and increases the secondary current.. At normal welding currents, the grid voltage applied to valves 73, 74 becomes negative, thus blocking them. To limit this grid voltage, transformer 4 is arranged to saturate.

[Also in Division B8] Tubular containers, similar to sausage casings, are shirred on a filling nozzle from which plastic substances are extruded against the sealed end of the tube until a desired length is obtained, the filling tube then being drawn off by other means whilst the filling pressure is relaxed to produce a break in the substance, the shirred part being rotated relative to the filled part or vice versa about their longitudinal axis to form a twisted closure in the tube material surrounding the break. The filling nozzle 2 is surrounded by a twisting pipe 6, the latter being rotatable at the filling end 8, the twisting pipe has a ring 10 which tensions a shirred tube 12 as it is drawn off by the substance. At a length defined by an adjustably positioned switch 17, the filling pressure is relaxed and grippers 18 draw the tube through a distance a, Fig. 2, which creates an empty portion of the tube. The tube 6, is then rotated, causing the empty section to twist Fig. 4 (not shown). The twisted portion can be augmented with stitching or clamping and the containers separated by severing. The twisting pipe is removeable so that different sizes can be fitted. A device, Fig. 5, for shirring the tube 12 onto a removed twisting pipe 6, comprises a ram 30 which reciprocates the pipe. After the leading end of the tube 12 has been manually drawn over the pipe, with the latter in the raised position grippers 35, advance to engage the tube. The pipe is then moved down gathering the leading tube portion at its upper end. The grippers withdraw, the pipe is raised and the grippers advance again. The pipe descends, to shirr a further tube length. This is repeated until the entire tube is gathered.

Abstract: 513,257. Coating with metals. ALEXANDER, P. March 2, 1938, No. 6543. [Class 82 (ii)] [Also in Group XL] In coating a support with aluminium or magnesium by thermal evaporation in vacuo, the heater and the support in the vacuum chamber are substantially surrounded by a layer of aluminium or magnesium and means are provided for subjecting the layer, as cathode, to an electrical discharge while a vacuum is maintained in the chamber, the residual gas being a gas inert to aluminium or magnesium, e.g., hydrogen. In the form shown in Figs. 1 and 2 the chamber 1 has a back 2 and a cover 3, the support 4 to be coated is mounted at 5, and a wire 8 of magnesium or aluminium fed from a bobbin 9 is vaporized by a heater 6. A plate 11 attached to the back 2 by insulating supports 12 carries a semi-circular sheet 10, and a plate 15 mounted on insulating supports 16 on the cover 3 is adapted, when the cover is closed, to make contact with another semicircular sheet 13, which is spaced from and overlaps the sheet 10 and is mounted on the chamber wall by insulating supports 14. The plates 11, 15 and the sheets 10, 13 are made of, or faced on their inner surfaces with, aluminium or magnesium, and can be connected to a source of alternating current by leads 17, 18. In operation the chamber is exhausted by the pipe 19 to a vacuum suitable for a glow discharge, hydrogen being introduced to constitute the residual gas through an inlet 20, and a glow discharge is caused to pass between the sheet 10 and the sheet 13. The discharge is then stopped, the vacuum reduced to a value suitable for thermal deposition, i.e., between 0.01 and 0.00001 mm. of mercury, and the deposition effected. In another form two concentric cylinders made of or faced with magnesium or aluminium surround the support and heater, the inner cylinder being perforated and, if faced, faced on both sides, the discharge being effected between the cylinders. In the form shown in Fig. 4, a complete casing formed by the plate 11 on the back 2, the plate 15 on the cover 3, and a cylindrical sheet 25 surrounds the heater &c. the discharge being effected by direct current between an electrode 26 and the casing, the latter being connected as cathode. Alternatively the casing may be formed by a film of aluminium or magnesium deposited on the inner walls of the chamber and the cover, in which case the corners of the chamber are preferably protected from the ionized gas by aluminium screens. Specifications 483,029 and 485,965 are referred to.
