Abstract: 1,054,524. Magnetic separators. W. G. GILL and H. T. READING. Nov. 30, 1965 [Dec. 29, 1964; June 28, 1965; Sept. 13, 1965], No. 50818/65. Heading B2J. A magnetic separator comprises a rotor 12 which is formed of a material of high magnetic permeability and mounted in a frame 10 for rotation within a stator having an even number of electromagnet pole cores 28, a shroud 30 of non-magnetic material mounted on the inner end of each pole core, means to pass slurry containing magnetic and non-magnetic particles to a space between each shroud and the rotor, means to supply washing water to the rotor adjacent each pole core, means to supply further washing water to the rotor at points midway between mutually adjacent pole cores and means to collect separately the magnetic and non-magnetic particles washed from the rotor. The rotor is of conical form and the periphery is provided with shaped portions which will give maximum and minimum flux density depending on the position of the rotor; the rotor therefore may be knurled or provided with projecting fingers or ridges 26 as shown which are arranged helically so as to direct the washing water vertically downwards during rotation. Slurry is supplied by a pipe 33, Fig. 1 (not shown) to the upper of two tanks 31, 32, the upper tank discharging into the bottom one 31 at a rate controlled by a valve operated by a lever 38. The bottom tank 31 is provided with a rotary distributer which passes the slurry via tubes 40 to feed boxes 41 adjacent the pole cores 28. Washing water from a ring main 49 is fed via tubes 45 and 46, Fig. 1, 3 and 4 (not shown), to the positions adjacent and midway between the pole cores respectively. The non- magnetic particles delivered to the gaps between the shrouds and rotor are washed to collecting funnels 43 and the magnetic particles are washed from the rotor into collecting funnels 47. The rotor is driven by a worm drive 20 and can be adjusted in height by a handwheel 14. The shrouds 30 are made of non- magnetic stainless steel with vertical corrugations to strengthen them and control the flow of slurry. Flexible wiper blades 130 serve to prevent spillage of slurry over the pole cores. Instead of the rotor being machined from solid metal, it may be built up from laminations. 36.

Abstract: 1,225,689. Screwing-up machine. O. KURZ. 27 Sept., 1968, No. 45955/68. Heading B3N. Apparatus for automatically and successively screwing screws into bores comprises an axially movable, screw-driving tool 23 driven through an adjustable overload clutch, means for picking up screws from a feeding rail 52, said picking up means comprising tongs 41, 42 having jaws 43, 44 and a cam 46 for opening and closing the jaws against a spring 45, means for shifting the tongs from the feeding means to underneath said tool in its retracted position (as shown) and control means for coordinating the movements of said tong-shifting, tong-spreading and tool-shifting means. The control means are cams 8, 9, 10 and 11 driven by a motor 5 through a reduction gear-box 7. Movement of the tongs and the tool is by pivoted levers which have rollers in engagement with the cams. In operation, the tool 23 engages and rotates a screw held in the jaws 43, 44 before the screw engages a bore. The jaws continue to hold the screw whilst it enters the bore for a short distance before the jaws are opened and moved to pick up another screw. The jaws can be made very thin to enable them to enter a recessed or countersunk bore.

Abstract: 1,226,072. Semi-conductor devices. SIEMENS A.G. 30 July, 1969 [31 July, 1968], No. 38156/69. Heading H1K. The surface of a Ge body is protected during diffusion of an impurity through a window in a masking layer by means of an additional layer of masking material covering the whole surface of insufficient thickness to prevent the passage of the impurity. The protective layer may be of SiO 2  having a thickness less than 500 Š and prevents oxidation of the Ge surface during the diffusion step. As shown, a PNP transistor is produced in a wafer 1 of P type Ge by pyrolytically depositing a thick layer 2 of SiO 2  on a polished and etched surface, photo-etching to produce a window, depositing a thin layer 4 of SiO 2  by pyrolysis of tetraethoxysilane, and forming an N type base region 3 by exposing to an oxidizing atmosphere containing phosphine (PH 3 ) or arsine (AsH 3 ). A thick layer 5 of SiO 2  containing P or of Si 3 N 4  is then pyrolytically deposited, a window 6 is etched through all three masking layers and Ga is diffused-in from an oxygen free atmosphere, e.g. argon, or by powder diffusion, to form a P- type emitter region 7. A contact window for the base region is then formed and Cr and Ag, or Al are vapour-deposited to form the contacts. An NPN transistor may be similarly produced using a thin oxide layer to protect the surface during the diffusion of the emitter region which is performed in an oxidizing atmosphere. Mention is made of the production of integrated circuits.

Egg comprises inner and outer sleeves initially of rectangular cross-section each of which is made from a blank of paperboard or plastics. The inner sleeve which has apertures 21 in opposed panels 19 is fabricated by folding along crease lines 20 and bonding flap 24 to the end panel 19. The outer sleeve is similarly fabricated by folding along crease lines 12 and bonding flap 15 to the end panel 10. The pack is assembled by inwardly folding each panel 19 along crease lines 22 to give two inclined and one vertical portion 23 and then sliding the inner sleeve within the outer so that panels 10, 18 frictionally engage. The Easter Egg 26 (dotted lines, Fig. 3) or article is inserted through one end past the two temporarily deformed opposed panels 19 into apertures 21 to be supported out of contact with panels 11, 18. Each outer sleeve flap 23 is then pressed inwardly into the respective aperture 21 to abut the inclined portions of panels 19 and to engage the inner edge of the vertical portion 23 so producing end openings having the waisted wine-glass shape shown in Fig. 3. The vertical 23 and adjacent inclined portions of the panels 19 project endwise beyond the ends of the outer sleeve to constitute pairs of stiffening end flanges of trough shape (Fig. 2).

The machine for making cross-bottom bags described in the parent Specification is modified by providing photo-detectors for receiving reflected light, which co-operate with stationary reflecting elements 306 which enter between the upper ply of a bag workpiece 316 and the inner half 317 of the bottom. The reflecting elements 306 are mounted on a plate 301 mounted parallel to the plane of conveyance at a distance above this plane exceeding the maximum thickness of the bag workpieces. A guide element 313 is, as shown, connected to the plate 301 by springs 311 which bias the guide element lightly downwardly so that its leading edge 314 engages the workpiece and enters between the body and the inner half 317 of the bottom as the workpiece travels in the direction of arrow 315. The ends 319, 320 of the guide and the plate are bent upwardly to ensure that the workpiece 316 reliably enters under the reflecting elements. In a modification the guide member is hinged to the plate and engages the workpiece under gravity. Specification 1,209,938 is referred to.
