Patent ES-214574-A1 (ES)
Title: Improvements in or relating to the smelting of materials containing lead and zine
IPC: C22B13/00
Filed: 1954-04-06
Abstract: In a process of smelting ores containing lead and zinc in a blast furnace the air blast and at least part of the charge are preheated to maintain the temperature at the top of the furnace at a high level, say 700-900 DEG C., the charge composition is controlled to give a reducing atmosphere in the offtake vapours which contain the zinc, and the metals therein are condensed in metallic form. To ensure a reducing atmosphere the proportion of coke used is increased above the normal. To ensure elimination of zinc from the ore air is fed into the furnace at intermediate levels as well as the bottom of the furnace. In treatment of sulphide ores these are roasted by a sintering process, mixed with fluxes such as lime and silica, and preheated to 500-750 DEG C. The coke may be separately preheated to 800-1000 DEG C. and the air blast to 550-800 DEG C. The lead recovered at the bottom of the furnace will contain nearly all the silver and gold, and some of the tin, antimony and bismuth contained in the ore. Copper will also be collected with the lead in metallic form or, in the presence of sufficient sulphur, as a matte.

Title: Pump
IPC: F04B1/14
Filed: 1968-06-07
Abstract: and FiN. A compressor or pump has a first stage pumping chamber defined between opposed cooperating frusto-conical surfaces 9, 13 of a fixed casing 1 and a wobble member 4 respectively, and one or more further pumping stages in the form of cylinders 37 containing pistons 36 reciprocated by the wobble member 4. The wobble member 4 is mounted on an inclined end portion of a shaft 10 rotated by an electric motor 33, 34. An axially extending partition 16 extends through a slot in the wobble member 3. Thus the rotating line contact between the frusto-conical surfaces 9, 13 causes fluid to be drawn into the first stage chamber through an inlet 2 on one side of the partition 16, Fig.3 (not shown), and causes fluid to be expelled through an opening (17) passing through the wobble member 4 and situated adjacent to the other side of the partition. Leakage from the first stage chamber is prevented by seals 29, 30. Fluid passing to the other side of the wobble member 4 is collected in a chamber sealed by a metal bellows 20 and passes therefrom into the pumping chamber of two cylinders 37 via valves 41 in the pistons 36. The fluid pumped from the cylinders 37 is passed through passages in the casing 1 in sequence to three other cylinders each smaller than the previous one, Fig. 2 (not shown).

Filed: 1969-12-19
Abstract: A web winding machine is provided with a loader adapted to receive and support a plurality of empty horizontally disposed reels which are successively loaded into a device for transfer from the loading location to a winding location. As shown, a loader for a winding machine of the "Pope" type comprises a pair of horizontal parallel bars 45 which engage the respective ends of empty reels 21 supported by the bars (Figs. 2 and 3, not shown). Chaindriven feeding members 55 (Figs. 4 and 5, not shown) urge the reels along the bars so that the endmost reel abuts against a pair of upwardlyprojecting members 59 loading arms 62 are movable to lift the endmost reel above the abutment members 59 and then lower that reel into reception by transfer arms 15 which can be operated to transfer the reel from the loading location to a winding location defined by a driven roller 13. When the diameter of the wound roll 29 reaches a desired value the arms 15 move the empty reel to engage the drive roller 13 so that the reel is brought up to speed pressure arms 31 are then moved so that the wound roll 29 is brought out of contact with the drive roller 13, the consequent slowing down of the wound roll causing a free loop of web 35 to be formed between the wound roll and the rotating empty reel. Air jets from nozzles 39 direct this loop to wrap around the empty reel when the web 35 then tears to separate the wound roll from the incoming web. With the winding of the empty reel thus initiated, the pressure arms transfer the wound roll 29 to a temporary storage position 40 from which the roll passes to a braking position 41 and then return to engage the new reel the transfer arms 15 then disengage that reel and return to the loading location to receive another empty reel from the arms 62, the movement of the arms 31, 15 and 62 being automatically controlled in timed relation to the winding cycle.
