Title: Refining of non-ferrous metals
IPC: C22B15/00
Filed: 1972-08-22
Abstract: 1424003 Refining copper IMI REFINERY HOLDINGS Ltd 4 Sept 1973 [22 Aug 1972] 39095/72 Heading C7D Secondary copper is refined by causing the molten metal to ascend an inclined path by means of electro-magnetic forces exerted on it while subjecting the metal to the action of one or more refining agents to reduce the impurity content of the metal. The inclined path may be in the form of a launder pump comprising a refractory lined channel with electro-magnetic means for advancing the molten metal up the channel and means for blowing air or gas on to or into the molten metal and/or means for applying heat to the molten metal. The refining process may be carried out using a plurality of launder pumps in each of which a different refining reaction occurs or in a launder pump having a plurality of successive zones in each of which a different refining reaction is carried out or may be carried out using a conventional converter in conjunction with a launder pump. Molten copper may be refined by treatment with silica flux, oxygen containing gases, caustic flux, phosphor copper or phosphate slag and reducing gases (e.g. propane, hydrogen or ammonia) as the refining agents in the process of the invention, removing iron, zinc, lead, tin and oxygen.

Patent GB-1243708-A (GB)
Title: Method and apparatus for handling dough products
Inventor: HARDING CHARLES EDWARD
IPC: A21B3/07
Filed: 1969-08-05
Abstract: 1,243,708. Removing baked articles from travelling hot plates. C. E. HARDING. 5 Aug., 1969, No. 39170/69. Heading A2A. Crumpets, muffins, drop scones, pancakes or pikelets are removed from hot plates 18 of a travelling hot plate conveyer 12 by bringing a hot plate to rest adjacent a set of knives 26 having scraping edges 28, moving the scraping edges of the knives into engagement with the surface of the hot plate, effecting relative movement between the knives and the hot plates to cause the edges of the knives to release the crumpets from the hot plate and to cause the edges 28 to pass beyond the edge of the hot plate, and effecting further relative movement between the knives and the hot plate to draw the knives back over the edge of the hot plate to perform a selfsharpening and self-cleaning action on the knives. The mechanism for performing this action comprises a cam shaft 78 carrying a pair of cams 76, a cam 84 and a cam 98. The cams 76 co-operate with follower rollers 74 to raise and lower a pair of side arms 72 which form part of a stripping frame 68, a forward end of which pivotally supports a saddle 67 to which a knife bracket 56 is secured. The knives 26 are mounted in knife carriers 36 each individually pivoted to the frame 68 by means of a pin 52 journalled in a pair of lugs 54 on the frame 68, a spring 62 urging each knife towards the hot plate, and an adjustable stop 64 being provided on the frame 68 opposite each knife carrier to limit such movement. Cam 84 co-operates with a follower roller (82, Fig. 4, not shewn) on a lever arm (80) the free end of which in turn acts on a further roller (70) carried by an arm (69) secured to the knife bracket 56, whereby the latter is rocked about the pivotal connection between the saddle 67 and the stripping frame 68, a spring 88 maintaining the parts in operative engagement. The cam 98 acts positively on the knife bracket 56 via a follower arm 96, in the opposite sense to that of the cam 84, so that in the event of failure of the spring 88 the knife carrier 56 will still be rocked. In operation, the knives are held away from the travelling hot plates 18 by the cam 84 until a hot plate has stopped in the position 18a, upon which spring 88 or cam 98 rocks the knife carrier 56 to place the knives 26 in engagement with the hot plate 18 and compress spring 62 to an extent sufficient to give the desired engagement pressure, after which cams 76 cause the knives to slide upwardly across the width of the hot plate to remove the baked articles, the knives subsequently being lifted off the hot plate and returned to their lowered position by further rotation of the cams. The travelling hot plates 18 form part of a known crumpet making machine which includes an upper conveyor 14 comprising a series of mould-ring plates 22 adapted to rest on the hot plates 18 during the passage of the latter through the machine, the two conveyors 12, 14 being driven in a step-by-step manner by a Geneva crank mechanism.

Filed: 1976-09-23
Abstract: 1513067 Blow moulding GILDEMEISTER CORPOPLAST GmbH 23 Sept 1976 [30 Sept 1975] 39447/76 Heading B5A Plastics parisons for blow moulding into bottles are made by heating both ends of a cold open-ended parison P, transferring it to a die assembly, gripping the parison intermediate its ends by clamps 10 while deforming one end to form a closed bottom, and also deforming the other end to form a neck by first axially displacing a core 26 into the parison which widens the end into contact with a die section 30 and then admitting pressure medium into the parison to complete the shaping of the neck, e.g. by forming threads in die recesses 43. The middle of the parison is gripped by the clamp 10 while being heated by means not shown and transferred to the die assembly while still gripped. Upper and lower clamps 14, 15 are closed about the parison. Inner and outer cores 24, 26 are displaced into the parison by drive means 22 until the core mounting cylinder 20 engages the die sections 30. An upper die 33 is lowered by drive 34 to shape and close the bottom of the parison which is then cooled by air passed through cavity 36 around the die. The outer core 26 is then displaced into the parison by admitting pressurised air into the cylinder 20 through opening 27. The chamfer on the core 26 expands the end of the parison and a shoulder 45 forms an accurate end face around the neck opening. When the core 26 reaches its forward position, longitudinal grooves 48 on the inner core 24 and a bore 49 in the outer core 26 admit air from behind the core 26 to the space 50 to inflate the parison neck at high pressure. The parison is carried by clamps 14, 15 to a blow mould at which it is blow moulded at a lower pressure to form a bottle.

Photographic apparatus has a pair of pressure applying members resiliently urged towards one another and which are disposed at opposite sides of a path for two superposed photographic sheets for spreading a processing liquid between the sheets, and also has an element with a front end surface for engaging and positively moving a leader attached to the sheets to move the sheets from one side of the pressure applying members to the other, a drive being provided to move the element and also to move a part which urges the members apart or reduces the force urging them together for as long as the element is disposed between the members. In the embodiment shown, a camera comprises a back portion including two parts 12, 26 hinged at 34 in which a film pack as described in Specification 684,592 is placed. This pack contains film units each of which comprises two photographic sheets, one photosensitive, with a breakable container of processing fluid arranged between them which unit is provided with a leading clip which is engaged by a slidable element 60 and moved between pressure rollers 40, 42 which break the container. The unit is then withdrawn manually from the camera through opening 36. Roller 42 is mounted on a pivoted lever 50 and is spring urged against roller 40. Element 60 has a leading part 76 and a rear part 75 and is movable in a channel formed by a cover-plate 68 and the camera back 28 by a knob 72, attached by pin 74 to part 75, which is movable in a vertical slot 70 in the back 28 of the camera. Cover-plate 68 is provided with a slot 92 for pin 74. As pin 74 moves down the slot to move the element 60 between rollers 40, 42 it rotates arms 88, 89 (Fig. 2) to the dotted position shown. As arms 88, 89 rotate they move levers 80 to which they are pivoted downwards and either (a) wedges 86 on the end of the levers are inserted between the rollers and move them apart or (b) (not shown) a two-arm lever is pivoted to move a spring and rotate lever 50 and roller 42 away from roller 40 or (c) levers 80 are arranged to pivot lever 50 directly. Specifications 714,412, 921,921 and 921,927 also are referred to.
