Title: Magnetic separating apparatus
IPC: B03C1/12
Filed: 1973-12-10
Abstract: 1413056 Magnetic separators H SPODIG 10 Dec 1973 [12 Dec 1972] 57119/73 Heading B2J A magnetic separator comprises a vertically arranged stationary housing 14 within which is rotatably supported a magnet system constituted by superposed magnets 5 and pole plates 6; a handwheel 24 or a motor (25) Fig 3 (not shown) for driving the magnet system by way of a V-belt 13; and a stripping box 19 having one wall 22 which is flexible and another wall 20 which bears tangentially on the housing 14. In use, liquid or solid material containing ferromagnetic particles for separation is passed dowwardly through the annular space between the housing 14 and an outer housing 1 having an inlet (2) and outlet (3) Fig 1 (not shown; the ferromagnetic particles are thus attracted to the housing 1 and are carried around its surface, by virtue of the rotating magnet system, with a degree of slip which promotes the detachment of any adherent non- ferromagnetic particles, thus improving separation efficiency. The attracted ferromagnetic particles thus pass into the box 20 through the wall 22, and are stripped from the housing 14 by the wall 20 for removal by a slide 21.

Title: Assembly comprising an outer member shrunk onto an inner member
IPC: B23P11/02
Filed: 1970-12-07
Abstract: 1331477 Assembling force fits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Dec 1970 [10 Dec 1969] 58017/70 Heading B3U [Also in Division F2] An assembly comprises an outer member, e.g. a toothed wheel 4 shrunk on to an inner member, e.g. a shaft 1, the members having respective contacting surfaces 5 and 2 and in one or both of which is formed an annular chamber 6 normally open to atmosphere via duct 7 in one of the members but which chamber can be connected with a source of liquid under pressure. The outer member has a further internal surface 8 surrounding but spaced from a further external surface 8 of the inner member. An annular space 18 normally communicates with the atmosphere via a duct 13 in one of the members, but liquid under pressure can be admitted via the duct 13 to the space 18. One of the further surfaces is formed with an annular recess 10 (Figs. 1 and 2) or 20 (Fig. 3) which receives, or can receive, a flexible sealing element 10 (Figs. 1 and 2) and not shown in Fig. 3. Removal of the outer member is achieved by introducing pressure liquid into space 18 (when the sealing element is in the recess 20 in the case of Fig. 3) so as to expand part 3 out of contact with the shaft and to exert a force on shoulders 16, 17 to move the outer member axially relative to the inner member. Assembly of the outer member on to the inner member may be achieved in the reverse manner, e.g. by use of a collet chuck. Introduction of pressure liquid into the chamber 6 causes the part 3 to expand to facilitate rotation of the outer member relative to the inner member.

Abstract: 1363927 Descaling UNIVERSAL OIL PRODUCTS CO 20 Dec 1971 [21 Dec 1970] 58968/71 Heading C7E  A method of descaling a stainless steel oil heater comprises one or more scale oxidation steps each followed by a reduction step, the steps being carried out in the range 510-677C. In the oxidation step, carried out between 1-7À8 atmospheres, 1-15 mole per cent O 2  is passed over the scale, preferably admixed with steam or N 2 . This is-followed by flushing with steam or N 2 , drying with air, and purging with N 2 . The reduction step uses the same pressure range, and 5-50 mole per cent of H 2 , or CO in the form of producer gas or gas from a cracking unit, is passed through. Flushing is carried out as before and the process can be repeated until the scale is loosened. It is then acidised in 1-5% citric acid at pH 2-6 to remove the loosened scale.

Control means is responsive to the sensing device for stopping both the moving belt 5 and the rotating drum 20 whenever there is less than a plurality of cigars on the ramp 18a. As shown, ramp 18a is transparent and a light source is positioned near one surface of the ramp. A photocell aligned with the light source is positioned near the other surface of the ramp so that cigars on the ramp determine the amount of light transmitted to the photocell. When the aparatus is functioning normally, the conveyor 5 is stopped by a counter as soon as a full row of cigars is collected. A pusher 12 then pushes the row into a loading box. The latter is lowered stepby-step as each row is discharged, and in itself discharged by a pusher when it is filled with a pre-determined number of rows. The plate 10 is made of transparent-plastics.
