Title: Improvements in and relating to a method of Continuous Coking of Coal
Inventor: ROSNER MANFRED
IPC: C10B49/16
Filed: 1968-07-30
Abstract: 1,172,189. Coking coal. BROWN, BOVERI & CO. Ltd. 30 July, 1968 [1 Aug., 1967], No. 36311/68. Heading C5E. In a process for continuously coking coal, the coal is mixed with an alkali metal compound which will be completely vaporized during coking, e.g. K 2 SO 4 , and the mixture passed through a plurality of coke ovens to produce coke oven gas containing the vaporized compound which is recovered e.g. by scrubbing, from the gas. The K 2 SO 4  speeds up degassing of the coal during coking. An apparatus for shaping the coke may be interposed between two of the ovens. In an example, 0.1 to 1.5% b.w. K 2 SO 4  is mixed with the coal which is passed through two ovens heated respectively to 400‹ and 1100‹ C. Each oven is heated by circulating an inert heat-carrier through a heat exchanger heated by the combustion gases from an MHD generator in which the coke oven gas is burnt. The combustion gases also pre-heat air for the generator, and raise steam which circulates through a turbine which drives a blower for the air.

Abstract: 1,271,238. Flocking. DUNLOP HOLDINGS Ltd. 30 July, 1969 [30 July, 1968], No. 36323/ 68. Heading B2E. [Also in Divisions B5, B6 and D1] A surface covering material comprising a base layer 1 and a pile of thermoplastic flock fibres 2 e.g. nylon has wear-resistant areas 3 produced by means of a heated shoe-plate 5 which causes the fibres to fuse together. One or more shoe plates 5 are brought in and out of pressured contact with the pile by means of an air operated piston and cylinder arrangement and comprise an upper attachment plate 14, an insulating block 15 incorporating an I.R. heater 17, a steel plate 16 and aluminium plate 13 secured together. A sheet of thermoplastic material 20 e.g. nylon felt may be laid on the pile and fused therewith. A layer of non-stick heat resistant material e.g. silicone-surfaced glass cloth 21 or an aluminium plate having a ribbed surface coated with silicone release fluid may be inserted between the shoe plate and the area to be treated to prevent adhesion. Cooling of the material may be accelerated by application of a cooled shoe plate after which additional thermoplastic flock fibres or powder may be sprinkled on the treated area and the process repeated. This additional material may be of a different colour to produce a patterned effect.

Abstract: 906,222. Photo-electric switching. STANDARD TELEPHONES & CABLES Ltd. Standard Elektrik Lorenz A.G.). Oct. 27, 1959, No. 36372/59. Class 40 (3). An arrangement for the simultaneous closing of a number of electrical circuits comprises an electro-luminescent layer which is energized to produce light operative upon a number of photoconductive layers respectively included in said circuits. In the arrangement shown in Fig. 1, the electro-luminescent layer 7 lies between transparent electrodes 6, 8 connected by a switch 13 to a voltage source 12. Photo-conductive layers 3 are disposed between an electrode 2 and individual electrodes 4 connected to respective loads 15 . . . 18 and a power source 14. Other photo-conductive layers with their electrode members are associated with loads 20 . . . 23 connected in parallel with a second power source 19. In a modified arrangement, Figs. 2, 3 and 4, a conductive layer 2 mounted on a transparent base 1 carries horizontal photoconductive layers 3 each coated with a conducting layer 4. On a further transparent base 5 is arranged a transparent conductive layer 6 on which are mounted vertical electro-luminescent strips 3 covered by conductive layers 8 which can be individually connected by a switch 13 to an energizing source 12. The horizontal conducting strips 4 are connected to a voltage source 14 and loads 15, 16 and 17. The operative areas of the photo-conductive strips 3 are normally determined by their three intersections with two vertical strips 7 in each position of the switch 13. The intersecting areas are made selectively operable by means of an opaque diaphragm 10 having square or rectangular apertures, Fig. 5 (not shown), corresponding to those intersections which are to be operative for the respective positions of the switch 13.

Title: Process for the separation of organic compounds
IPC: B01D53/02
Filed: 1957-11-22
Abstract: <PICT:0871497/III/1> In a process for separating mixtures of organic compounds by extraction, the mixture is fed to a column A in which a solvent liquid flows in counter current with an eluent gas, whereby a component is concentrated in a zone SB from which it is withdrawn and fed into a second similar extraction column B provided with counterflowing solvent and eluent gas where the desired component is freed from other components, and the latter are returned to column A. Thus a mixture of five components C1 . . . C5 are separated in column A by adjusting the flow rates and temperature gradient whereby components C1, C2, C3 rise and C4, C5 fall in the column.  C1 flows out at the top with the eluent gas and C5 with the solvent at the bottom.  The conditions of temperature and flow rates are arranged so that a concentrate of component C3 forms at zone SB and this in the second column B is freed from components C1 and C2, which rise to the top and are recycled to column A, and C3 which falls to the bot tom. As solvent liquid there may be used liquid hydrocarbons, silicones, esters, ethers, nitriles, or alcohols.  Eluent gases include air, methane, CO2, hydrogen, and steam.  The mixtures separated include, hydrocarbons, azeotropic mixtures, essential oils, and alcohols.  The process may be applied in the form of a chromatographic column to monitor chemical processes.  The columns are preferably packed with an inert solid but Raschig rings and similar bodies may be used. Specifications 871,491, 871,494, 871,495 and 871,496 are referred to.

[Also in Group XXII] An encapsulation for a semi-conductor device 16 includes a lead 13 carrying a platform 17 supporting the device, and has means forming ohmic contact with one surface of the device which comprise a predetermined length of metal ribbon 14 bent into the shape of a stirrup having a rounded base which contacts the device, at least the base of the stirrup being cupped so that the portion contacting the semi-conductor device is rounded in two directions. As shown, the encapulation is provided for a PNPN diode whose main faces are metallized, preferably with gold, by known techniques. The diode is held within its glass envelope 11 by " Kovar " (Registered Trade Mark) or Dumet leads, lead 13 being attached to a gold platform 17 and the other lead 12 being secured to a platinum side stirrup (e.g. 95% Pt./5% w.). Sufficient force is applied to the lead 12 before it is sealed to the envelope to ensure that cold pressure bonds are formed between the stirrup and platform and their respective surfaces of the diode. The diode may instead be fixed to the platform by soldering or by other known methods.

Abstract: 927,523. Electromagnetic relays. WESTERN ELECTRIC CO. Inc. Oct. 27, 1960 [Nov. 27, 1959], No. 36880/60. Class 38 (5). The fixed contacts of sealed mercurywettable contact device are wettable only in the area which is engaged by the movable contact which has a projection arranged to intercept mercury ejected from the contacts during operation. Nickel-iron polepieces 11, 12 and the fixed contacts 17 secured thereto are plated with chromium-oxide to which mercury will not adhere. Three contact faces 18 are ground on each contact 17 to remove the chromium-oxide and these faces 18 co-operate with the armature contact 15 which has capillary grooves for the mercury. Two projecting baffles 16 are secured to the armature 15 so that when the armature moves into engagement with one of the contacts 17, due to an energizing coil (not shown) and biasing permanent magnet (not shown), the corresponding baffle 16 is " nested " within a respective recess 11a, 12a in the polepiece 11 or 12. Some of the mercury which is squirted from between the contacts on impact will be intercepted by the baffle 16 or recess 11a, 12a and be deflected by the baffle back to the armature. Any mercury which spatters on to the fixed contacts or polepieces will run off and fall into the pool 14. This arrangement limits the amount of mercury on the fixed contacts to prevent short-circuiting and ensure break-before-make operation even if the device is tilted. U.S.A.
