Title: Improvements relating to welding
Inventor: APBLETT WILLIAM RICHARD
IPC: B23K9/028
Filed: 1966-06-23
Abstract: 1,142,572. Welding by fusion. FOSTER WHEELER CORP. 23 June, 1966, No. 28222/66. Heading B3R. In fillet welding, e.g. tubes to a tube plate, welding is effected by a non-consumable electrode supplied with pulsating direct welding current the pulsations of which produce a wave motion in the weld pool. Welding is effected in one or two passes with or without filler material. The pulsing frequency is 0À5-10 cycles per second, the minimum pulse amplitude is 20 amps and voltage is 7-14 volts. The electrode has a frusto-conical tip and its axis during welding is at 10-30 degrees to the axis of the tube. A shielding gas, e.g. argon, is used. The welds are between a stainless steel clad carbon steel plate and stainless steel tubes, or both workpieces may be of a nickel-based alloy containing chromium and iron. The welding rate is 0À02-0À093 inch per current pulse.

Title: Method of producing a drying filter
IPC: B01D53/28
Filed: 1973-06-14
Abstract: 1432383 Moulding filters DANFOSS A/S 14 June 1973 [3 July 1972] 28370/73 Heading B5A A method of producing a drying filter comprises the steps of mixing silica gel particles with a powder containing epoxy resin components, the mixing being performed at a temperature below that at which the components react, and subsequently compressing the mixture at a temperature sufficiently high to cause reaction of the components and hardening of the resin. In an example, silica gel particles of mean size 0À5 to 3 mm. were mixed at room temperature with an epoxy resin powder of particle size less than 70 microns and the resulting mixture was pressed for five minutes at 190‹ C. and 20 kg./cm.<SP>2</SP>. After opening of the mould the compact was heated at 190‹ C. for a further two hours to effect complete hardening of the resin. The mixture used preferably contains 5-8% by weight of resin powder. To ensure adherence of the resin powder to the silica gel particles, the powder is preferably electrostatically charged, but this may occur as a result of the mixing process.

[Also in Division A2] In mechanism for packaging finished multitier cakes constituting the final mechanism in an automatic installation for making and packing such cakes (see Division A2), each cake is lifted, by a lifting and lowering appliance, from its conveyer to a position between and above two moved-apart holding plates. These plates are then moved closer together and the table is lowered to leave the cake supported on the plates and to receive the lowermost empty box pushed, by a pusher 107, out of a vertical stack of empty boxes in a store 13, Figs. 1 and 11. The holding plates are then moved apart, so that the cake is deposited in the box and the table is lowered still further to deposit the filled box on said conveyer, which carries it out of the installation. Upper and lower electrical contacts 121 may be installed at the level of the 10th and 2nd empty box from the bottom of the store 13. When ten or more boxes are in the store, the upper contacts are kept open, but, when the number falls below ten, said contacts close and cause a warning signal light indicating "Boxes Needed" to be switched on. When only one empty box remains in the store 13, the lower contact stops the electric motor 18 driving the installation. Specification 1,103,646, relating to automatic lift-drop tables, is referred to.

Title: Improvements in the production of colloidally soluble aluminium hydroxide
IPC: C01F7/02
Filed: 1956-09-19
Abstract: Aluminium hydroxide containing basic aluminium salts of strong acids is rendered colloidally soluble in water by treating, preferably in the dry state, with steam at superatmospheric pressure.  The initial material is prepared from an alkali metal aluminate solution by precipitation with a strong mineral acid or from an aluminium salt of a strong mineral acid, e.g. from aluminium chloride by reaction with caustic acid.  In an illustrated embodiment, nitric acid is used to precipitate alumina from sodium aluminate the temperature being maintained at 40-50 DEG  C. and the pH at 7.0-7.3; Bohmite is formed, which may be filtered, dried and ground and then treated with steam at 5-12 excess atmospheres whilst spread on stainless steel plates arranged on gratings in a pressure-tight chamber.  If desired the chamber may subsequently be evacuated to facilitate removal of moisture from the alumina, and the product may be ground.  A prior art statement refers to the preparation of colloidally soluble alumina by (1) peptizing precipitated aluminium hydroxide with an acid and evaporating the so-formed sol to dryness; (2) reacting a dilute aluminium amalgam with an aluminium salt solution or dilute monobasic mineral acid; (3) decomposing aluminium alcoholates with dilute acids; (4) electrolysing aluminium chloride solution; and (5) passing ethylene oxide into aluminium chloride solutions, distilling off the ethylene chlorhydrin and evaporating to dryness.

Abstract: 788,957. Modifying metallic surfaces. PYRENE CO., Ltd. Sept. 28, 1956 [Oct. 7, 1955], No. 28655/55. Class 82(2)  In the production of phosphate coatings on metal articles by spraying a solution on to the work, the sludge contained in the whole of the solution collected during the spraying is removed as a slush by passage through cyclones so as to leave a clear solution, and the slush is then filtered to recover the solution in it. The Figure shows a process in which spraying is carried out in a booth 2, sludge-containing solution collected by funnel 4 passing through pipe 6 to pump 10 which feeds it to header 12 supplying twenty hydrocyclones 14. Clear solution is removed from the cyclones by manifold system 16 and returned to reservoir tank 8 (from which the solution is pumped to the sprays) through pipe 18, while slush is removed by manifold system 20 and pumped through one further cyclone 24, the clear solution from which is returned to funnel 4 through pipe 26, to pass again through the cyclones, and the slush from which is passed to a travelling band filter 28 through pipe 30. The solution obtained from filter 28 is returned to reservoir 8 through pipe 32.

In one embodiment, Fig. 1, both the screen 7 and the original 43 to be copied are moved (to the left as shown) during line by line exposure, the precharging corotron 15 and the optical system remaining stationary. A corotron 19 is then moved across the screen 7 while it is stationary above the copy sheet 17. The secondary latent image bearing copy sheet 17 is then passed through a liquid development apparatus 22, fixing means 23 and discharged from the machine. In other embodiments, various combinations of moving or fixed original carriers, moving or stationary precharging corotrons, moving or stationary line by line optical systems or stationary flash exposure, and screens moving or stationary during exposure are used. In one such other embodiment, two or more screens are mounted on a turntable for sequential exposure at a fixed original position, optionally through colour separation filters if colour copies are required. A micro reader/printer is also disclosed. The screen 7 comprises a metal, e.g. wire, screen 32 coated with photo-conductive material 33, Fig. 3. Where multiple copies are required to be made from a single primary latent charge image on the screen 7, retention of the charge can be improved by use of a metal screen 157, Fig. 15, in which the photo-conductive coating 158 is overlaid with an insulating coating 159.

Abstract: 1,192,446. Photographic film cartridge. EASTMAN KODAK CO. June 23, 1967 [June 23, 1966], No. 29005/67. Heading G2A, A film cartridge has a moulded plastic interior wall which defines a chamber for containing or receiving a supply of strip material in or into coiled form, and has flexible fins integrally moulded with the interior wall at a mouth of the chamber and projecting inwardly away from said wall so as to engage the strip material in the mouth. The fins at the mouth 24 of the chamber, Fig. 2, may extend right across the mouth to form a light trap through which the film 28 may pass. In the body of a supply chamber further fins may hold the coil of film strip material away from the chamber wall and said fins may be in pairs, each fin 18 being only wide enough to engage the edge of the film strip. The interior wall carrying the fins may be moulded integrally with the cartridge or may comprise a moulded insert which fits inside the cartridge. In the body and the mouth of the supply chamber and in the mouth of a take-up chamber, Fig. 3, the fins may be angled so as to oppose movement of the film strip into a supply chamber and out of a take-up chamber. The supply chamber and take-up chamber may be rigidly connected (not shown) to form a factory-loaded film cartridge for use with a suitable camera.
