Abstract: 892,028. Semi-conductor devices. BENDIX CORPORATION. June 26, 1959 [July 25, 1958], No. 22071/59. Class 37. A method of making a semi-conductor device comprises coating a semi-conductor body with a solution of an oxygen compound of a group III or V element, evaporating the solvent and then heat treating the body under such conditions as to slowly reduce the compound and diffuse the released element into the body. In an example, a saturated solution of antimony trioxide is prepared by mixing pure antimony trioxide with glacial acetic acid, agitating the mixture, allowing solid matter to settle out and filtering the liquid residue. The solution is then applied to the lapped germanium wafer which after evaporation of the solvent in air is fired at 900 C. for 3 hours in an atmosphere of nitrogen or a reducing gas. In another embodiment indium hydroxide is used in place of antimony trioxide.

Patent GB-224241-A (GB)
Abstract: 224,241. Pantoflicek, B. Nov. 1, 1923, [Convention date]. Projectile fuzes.-A safety device is made up of one or more rows of single centrifugal elements arranged one behind the other and adapted to move step by step in the direction of the row and to be ejected from the row one after another to delay the operation of rendering the fuze active. In the form shown in Fig 1, a ring 25 sets back by inertia against a spring 28 when the projectile is discharged, and is retained in the retracted position by a catch 26 snapping into a recess 27. Lateral ports 20, 21 are thus uncovered, through which a number of discs 15 escape successively as they are moved forward with the detonator 5 by a spring 10. The detonator 5 is finally brought against a cover plate 18, in which position it can be reached by the firing-pin (not shown); and, simultaneously, a primer 6 is brought opposite passages 8 leading to the charge 7. In a modification, the ports for the discs are opened by the expansion of a segmental ring by centrifugal force against the closing action of a spring; and the spring 10 serves to actuate the firing-pin instead of arming the detonator. In other modifications, centrifugal balls arranged in longitudinal or circular passages are used instead of centrifugal discs as above.

Title: A process for the separation of magnetisable and contaminating non-magnetisable particles present together in suspension in a liquid, and apparatus therefor
IPC: B03B5/44
Filed: 1955-08-04
Abstract: 802,433. Washing granular materials. STAMICARBON N.V. Aug. 4, 1955 [Aug. 11, 1954], No. 22494/55. Class 82(2) Magnetizable and contaminating non- magnetizable particles in suspension in a liquid, e.g. as in the heavy separating medium for a coal or ore washing process, are separated by a process which includes feeding the suspension to a magnetic separator 8 which removes the bulk of the magnetizable particles at 9, whilst the remaining suspension containing the rest of the magnetizable particles is wet screened at 13 to separate at least part of the said magnetizable particles from coarser contaminating particles using the method of any of Specifications 791,520, 791,857, 791,858 or 791,859 [all in Group I]. In the method and appartus described, raw coal is fed at A, the resulting coal and shale fractions being discharged at B, C respectively after separation in a magnetite suspension. Dilute suspension obtained by continually rinsing the separated fractions is led via 2 to a preliminary screening such as by the curved deck of spacer bars 3 (where the method of Specification 791,520 may be used), or by a cyclone or thickener. About 90 per cent with fine magnetite passes through to tank 4 and thickener 6, the remainder being led to the magnetic separtor 8 whence the magnetite collects at 9 and is led to thickener 6 while the non-magnetic and fine magnetite particles collect at 11 and are led to the wet screening deck 13 for separation treatment by the method of any of the above Specification 791,520, &c. The fine particles collect at 14 and may either be returned via 15 to the regenerating circuit, or led to thickener 6; the coarsest particles are discharged at 16. Part of the overflow from thickener 6 is preferably re-introduced via 17 to the wet screen 13, while part may be discharged at 18; the remainder being led back via 20 for use in rinsing the coal and shale fractions. Thickened suspension returns via 19 to the coal washing apparatus for re-use as the heavy separatory medium.

Title: Apparatus for separating coke or other substances which are good conductors of electricity from ashes or other substances, which are non-conductors or bad conductors of electricity
IPC: B07C5/344
Filed: 1922-08-18
Abstract: 206,273. Lelarge, H. Aug. 18, 1922. Magnetic and like separators.-Apparatus for separating electrically conducting material, such as coke, from non-conducting material, such as ashes, comprises a series of bladed endless-band conveyers 3 which pass fragments of the material to be separated from an inclined plane 1 beneath contact members 20 which form part of an electric circuit adapted to control the position of movable separating members 19 according to whether a passing fragment is conducting or non- conducting. The conveyers 3 are separated by discs 16 and are mounted on drums 4, 5, one of which is intermittently rotated by a ratchet wheel 8 and hooked lever 9, the lever receiving its movement from a cam 10 on the driving shaft 21. A second cam 17 is mounted on the shaft 21 which cam operates, through the medium of levers 27, 14, 26, 24, the separating-members 19 causing them to be brought into the raised position shown in Fig. 5 each time a fragment is passed beneath the contact members 20. The separating-members 19 are each provided with a hook 21 which is adapted to engage a hook 22 formed on the armature of an electromagnet 29 which is energized only when a conducting fragment passes beneath the corresponding contact 20. Passage of a conducting fragment causes the armature of the magnet to be attracted, thereby disengaging the hooks 21, 22 and allowing the separating-member to fall to the position shown dotted in Fig 5, when the fragment will proceed down the inclined plane 31. When a non-conducting fragment passes, the separating-member is retained in the raised position, thereby directing the fragment beneath the apparatus. The members 20 are movable and are brought into position for contact with each passing fragment by a rod 12 which receives its motion from the cam 17 operating the separating members 19. Inclined coacting surfaces are provided on the hook members 21, 22 whereby each armature is brought into close proximity to its electromagnets each time the separating members 19 are brought into the raised position.

Abstract: 1,219,592. Folding edges of sheet material. CLARKS Ltd. 15 May, 1968 [16 May, 1967], No. 22784/67. Heading B5K. A marginal portion 10a of a sheet 10 of foldable material is folded over by locating the sheet 10 on a supporting surface with the portion 10a overlapping an edge upstanding from the supporting surface, pressing the sheet into the angle between the supporting surface and the upstanding edge so that the portion 10a lies against the upstanding edge, and causing to spread laterally an elastic body 16 which is disposed to the side of the portion 10a remote from the sheet 10 and whose lateral boundary is adjacent the upturned portion 10a whereby the body in spreading laterally engages and folds over the upstanding portion 10a. As shown, the sheet 10 comprises a J-shaped leather blank of a shoe upper, which has previously been skived along the fold line on the flesh side and a pressure sensitive adhesive applied to the marginal portion 10a, and is disposed in a jig 11 on a rigid platform 12. The jig 11 comprises a tray 13 containing plastics resin 14 and a J-shaped channel 15 is defined between the resin 14 and the solid rubber body 16. The lateral boundary of the body 16 constitutes the upstanding edge against which the portion 10a is folded. J-shaped clamping and pressing tools 17, 18, respectively, are lowered together so that the tool 18 presses the skived part of the blank into the angle between the body 16 and the tray 13, Fig. 3 (not shown). The tool 18 is withdrawn whilst the tool 17 remains lowered and a flat-ended tool (19), Figs. 4 and 5 (both not shown), is lowered to compress the body 16 between the tool (19) and the tray 13 so that the body 16 expands laterally and folds the portion 10a over against the main part of the blank 10 so as to be held by the adhesive. In modifications (all not shown), (a) the tools 17, 18 are omitted and the material is pressed manually into the angle between the elastic body and the tray; (b) instead of skiving the material along the fold line, two bands of adhesive are applied respectively to the portion 10a and the region against which the portion 10a is to be folded; (c) the solid body 16 is replaced by a sealed rubber skin filled with water or air and its outer boundary is defined by a flexible aluminium strip standing on its edge and the water in the body may be heated in which case a pressure sensitive adhesive is applied to the blank; (d) the elastic body and the inner boundary of the channel are formed by a metallic plate which has been dipped into liquid butyl rubber; and (e) vacuum means are provided for performing or assisting in the clamping of the blank 10 in the jig.
