Title: Charge coupled devices
IPC: H01L29/762
Filed: 1973-06-13
Abstract: 1415436 Semi-conductor devices WESTERN ELECTRIC CO Inc 13 June 1973 [14 June 1972] 28052/73 Heading H1K Between each electrode 14X, &c., in a succession of electrodes in a CCD there is a symmetrically placed zone which even when the device is not energized contains mobile charge carriers of the same polarity as the information-carrying carriers in the operative device, the concentration of three mobile carriers being high enough to prevent complete depletion of the zone with operational potentials present. The zones therefor remain conductive. The device shown is a 2-phase arrangement with a lightly doped N- type body 12 in which potential barriers to prevent even transfer are provided by N-type regions 16X, &c., overlapped by the trailing (sic) edge of each electrode 14X, &c. The P- type zone 18X, &c., is symmetrically formed by uniform implantation or diffusion but has a region 20X, &c., where partial compensation occurs due to winding with the initial N- region 16X. Electrode size and spacing and zone widths are chosen to allow for manufacturing tolerance and to ensure that the electrode always overlaps a certain minimum width of N- zone. The variation along the P-zone does not matter providing the partially compensated region 20X is now completely depleted. The silicon oxide layer 13 and the electrodes 14, 15 may be protected with a layer 24 of phosphorous glass, silicon nitride or aluminium oxide or with a further layer of silicon oxide. The P zones could be formed by silicon gate or refractory gate trichology or could be formed before the electrodes. Variant devices may be 2- phase devices in which the barriers are formed by the use of stepped oxide instead of by N- type zones, and devices of the 3-phase type where barrier formation depends solely on the potentials applied.

Title: Improvements in or relating to method and apparatus for purifying solid carbonaceousmaterial selected from the class consisting of coke and ahthracite coal
IPC: C10B19/00
Filed: 1951-12-03
Abstract: In a process of purifying coke or anthracite by treatment with chlorine at a high temperature the material to be purified is passed successively and continuously in successive quantities through a pre-treatment zone and a chlorination zone in which the material is heated to drive off volatile hydrogen containing material and is treated with chlorine respectively, the gases from each zone being separately withdrawn and the communication of gas from either zone to the other being prevented.  The pre-treatment zone is preferably heated to at least 1,000 DEG  C. and the chlorination zone to at least 1,400 DEG  C., the holding time of the material in each treatment may be in the region of 6-10 hours.  Apparatus described for carrying out the process comprises a cylindrical furnace 10 having a refractory lining 12 and divided into three zones, a pretreating zone 18, an intermediate zone 30 and a chlorination <PICT:0729129/III/1> zone 20, by sliding dampers 31 and 32.  Coke or anthracite to be treated is charged into the uppermost zone 18 where it is heated by vertically separated sets of carbon electrodes 21 and 22 to the desired pretreatment temperature, any gases liberated escaping through an outlet 28.  By operation of the dampers 31 and 32, pretreated material from the zone 18 passes to the intermediate zone 30 and material in the zone 30 is charged to the chlorination zone 20, the operation being so conducted that chlorine from the zone 20 does not enter the zone 18.  The zone 30 has a gas outlet 44.  In the zone 20 chlorine is admitted through an inlet 25 and gases containing unreacted chlorine and volatilized chlorides of iron, silicon and titanium pass out through an outlet 26 while the temperature of the material under treatment is raised by further electrical heating, spaced set of carbon electrodes 23 and 24 being provided.  The purified coke or anthracite is withdrawn through an opening in the chamber 15.  The dampers 31 and 32 may be operated manually, electrically or as shown by connections 37 and 38 to the pistons of fluid-pressure operated cylinders 41 and 42.  In a modification the material may be fed from the pretreatment zone to the chlorination zone by means of a screw-feeder disposed in an intermediate zone and having openings in communication with the two zones at opposite ends of the screw.  Specifications 715,478 and 716,718 are referred to.

In a second modification, Fig. 10 (not shown), the tubes are mounted parallel to the translucent screens and again project over optical paths including 45 degree inclined mirrors.
Patent GB-369913-A (GB)
Title: Process for recovering sulphur
IPC: C01B17/06
Filed: 1930-09-25
Abstract: Sulphur is removed from multiple ores, such as copper or copper-zinc ores, by a preliminary roasting and smelting operation with carbon to reduce some of the iron sulphide present to form free iron, sulphur dioxide being produced; alternatively, free iron may be added to the molten matte.  Sulphuretted hydrogen is then produced by treating the cooled and crushed matte with a dilute acid, e.g. sulphuric acid, which may be derived from the sulphur dioxide evolved in the first treatment.  Sulphur is obtained by causing the sulphur dioxide and sulphuretted hydrogen to react in the presence of a catalyst such as silica gel, natural or artificial zeolites containing aluminium or trivalent iron and an alkali or alkaline earth metal, e.g. glauconite or bentonite. A suitable artificial zeolite may be prepared by adding water glass to a solution of sodium aluminate and stirring until the reaction is complete.  The separated precipitate is dried at 100 DEG F. after which it is washed to effect decrepitation.  The mixture of sulphur dioxide and sulphuretted hydrogen is passed, at atmospheric temperatures, through catalyst beds in series and the sulphur deposited is extracted with ammonium sulphide solution which is driven off by boiling and condensed, the sulphur remaining in the vessel.  The catalyst is washed with ammonium sulphide solution and treated with steam to remove the sulphide. Alternatively, the catalyst may be treated with steam or water under pressure to melt out the sulphur, or be extracted with commercial ortho dichlorbenzene at about 110 DEG  C. and the saturated solution cooled to deposit sulphur, after which the solvent may be re-used.  Traces of solvent are removed from the catalyst and sulphur by steam.  The Specification as open to inspection under Sect. 91 (3) (a) states also that activated charcoal alone or mixed with artificial zeolites or silica gel may be employed as catalyst in the reaction.  The activated charcoal is obtained by heating wood, lignite or coal at a low temperature, below 600 DEG  C., and subsequently treating it with air or steam.  Mixture of the charcoal with the artificial zeolite or silica gel is effected by mixing the charcoal with one of the constituents of the gel, adding the other constituent, permitting the mixture to gel and drying at a low temperature; two parts by weight of charcoal to one of gel may be employed.  This subject-matter does not appear in the Specification as accepted.
