Title: Improvements in or relating to devices for measuring direct currents
IPC: G01R19/20
Filed: 1965-06-08
Abstract: 1,103,120. Direct current measurement. CKD PRAHA NARODNI PODNIK. June 8, 1965 [June 30, 1964] No. 24159/65. Heading G1U. [Also in Division H3]] An arrangement for measuring the sum of several direct currents incorporates individual transductors Tr 1, Tr 2, ... Tr n to which the currents are applied and from the outputs of which D. C. signals proportional to the individual currents are obtained. These signals are applied to a summation transductor ST which provides an output proportional to the required sum. A neutralizing transductor KT is included in such a way that the D. C. control windings R 1 , R 2 , ... R n  of the summation transductor and respective D. C. windings P 1 , P 2  ... P n  of the neutralizing transductor are series connected, and the A. C. windings 1 of both the summation and neutralizing transductors are energized from alternating voltages in the same phase. An additional D. C. control winding P v  of the summation transductor is connected to an adjustable high impedance source of direct current. The magneto-motive force produced by P v  is greater than and in the opposite sense to the total of that produced by the other windings P 1  -- P n , and is adjusted so that parasitic A. C. induced in the control windings of the transductor ST is balanced out by that induced in the windings of the transductor KT. Neither the partial or total measurements will then be effected by the induced A. C.

Title: Process and apparatus for removing sulphur dioxide from flue gas
IPC: F01N13/02
Filed: 1965-06-09
Abstract: <PICT:1103859/C1/1> SO2 is removed from flue gases by passing them through a reactor having a plurality of independent compartments containing a porous bed of catalyst which accelerates the oxidation of SO2 to SO3.  The reactor has duct means for directing the flue gases through the compartments and a means for selectively isolating one or more of the compartments to enable purging gas to be passed into the isolated compartment so as to re-activate the catalyst while passing the flue gases through at least some of the remaining compartments.  As shown in Fig. 2, SO2-containing flue gases, after passing through an electrostatic dust precipitator (38), see Fig. 1 (not shown), enter the cylindrical reactor through duct 72 and pass through those radially spaced cells 52 containing catalyst which are not isolated by hood members 82, 84.  The cells 52 have highly perforated walls.  The treated flue gases leave via duct 74. Hood members 82, 84 of sectorial cross-section rotate about shaft 91 fitted with a slip-joint 93 and thus are able to isolate a radial set of cells.  The purging gas passes through duct 89, the lower hood 84, the isolated cells, the upper hood 82 and out through duct 88.  The particulate catalyst is retained in the cells 52 by valve 56.  When this valve is opened the catalyst falls through hood 84 to duct 70 which is closed by a removable plate 76.  After closing valve 56, as shown in the drawing, further catalytic material, e.g. V2O5, can be admitted to the cells through tube 92 and a series of branch ducts 94.  The purge gas can be supplied to the reactor through a preheater, e.g. so as to heat the catalyst to 700-750 DEG  F.  The purge gas can be recycled to the preheater or can be mixed with the flue gases before they enter the dust precipitator (38).  A heat exchanger (36) for the treated flue gases also warms the combustion air that is passed to the furnace (32) providing the flue gases.  The SO3 in the flue gases combines with water also in the flue gases to form H2SO4, this is collected in a mist precipitator (42).  S-free gases are exhausted through a stack (44).

IPC: H05B33/00
Filed: 1966-06-03
Abstract: 1,185,832. Electro-luminescence. THORN ELECTRICAL INDUSTRIES Ltd. 15 March, 1967 [3 June, 1966], No. 24950/66. Heading C4S. [Also in Divisions H1 and H5] An electro-luminescent device comprises electrodes 11, 15, electro-luminescent layer 12 (e.g. ZnS in an organic resin or lacquer or green, blue, yellow phosphors or blends thereof), irradiation responsive (e.g. X-rays, U.V., or cathode rays) dielectric layer 13 (e.g. ZnO in a nitro cellulose-butyl acetate lacquer or ZnS), and a high dielectric constant layer 14 (e.g. barium titanate, barium strontium titanate or titania in a vinylidene copolymer binder). The device emits light on application of an A.C. field either during or soon after irradiation, and continues to luminesce after cessation of irradiation while the field is maintained. Emission ceases on subsequent removal of the field but recommences on re-application of same within a certain time. The irradiation responsive material stores for not less than five minutes at room temperature in the dark, is returned to its original state by heating or infra-red radiation, e.g. to a temperature of 80‹ to 150‹ C., and has a resistance greater than 10<SP>6</SP> ohms. cm<SP>3</SP>. In fabrication, the phosphor layer 12 is dried at 100‹ to 120‹ C., the solvent of layer 13 evaporated at 100‹ to 120‹ C., and layer 14 heated at 90‹ to 100‹ C. Layer 12 may also be applied by a vitreous enamelling technique. Conducting surface 15 which may be opaque may be either colloidal graphite or silver, or, particularly for electron irradiation, evaporated Al or Au, conducting layer 11 being tin oxide. Layer 13 thickness should not exceed the combined thicknesses of layers 12 and 14 and be not less than 1% of the phosphor layer thickness. In cathode ray tubes, the panels are preferably free from organic binders. X-ray intensifying materials such as calcium tungstate may replace part of the dielectric material. Applications include medical and dental X-ray work, non-destructive testing of materials by X-rays, detection of radiation from radio-active materials, lasers and cathode rays. Infra-red detection may be achieved after uniform excitation by X-rays. Flexible constructions may be as in Specifications 1,129,816 and 1,107,842 with a further ZnO layer.

Abstract: 459,201. Glass manufacture. WURTTEMBERGISCHE METALLWARENFABRIK, and DEBACH, H., 19, Eberhardstrasse, Geislingen - Steige, Wurtemberg, Germany. Sept. 7, 1935, No. 24989. [Class 56] A method of making a glass article having a hollowed or recessed foot comprises the operation of forming the recess in the foot by means of centrifugal force. A hollow body 1, Fig. 2, is blown on a pipe 2, and a heavy foot portion 3 containing a relatively large quantity of glass is applied to the body in the usual way. When the foot portion 3 has cooled to such an extent that the glass in the outer part 3a has set, the body is spun on its longitudinal axis by means of the pipe 2. As a result, the hotter and still plastic glass in the interior of the foot 3 spreads laterally under the action of centrifugal force, finally taking up the position indicated by the lines 7, Fig. 5, and leaving the required recess in the foot. If an article of oval cross-section is required, the sides of the body are flattened in the known way before the spinning process. The parts 3a may be cooled before the spinning, or the foot may be reheated at a glory-hole if the portions 3a are also required to spread to form a splayed-out foot.

Abstract: 747,723. Coking; gas-producers. METALLGES. AKT.-GES. Oct. 6, 1952, No. 25029/52. Class 55(1). Powdered or granular heat carriers move in a cycle in which, after emerging from a chamber 1 in which they give up heat in the low temperature carbonisation or gasification of carbonaceous fuels, they enter a heating space 2 at a point remote from its bottom, are therein maintained in a fluidized state and heated by the combustion of fuel with air introduced into that heating space in quantities sufficient for fluidization and are then conveyed by the combustion gases through a conduit 3 merging into or joining the upper part of the heating space, the velocity of the gases in the heating space 2 being lower than those necessary in the conduit 3 for pneumatic conveyance of the heat carriers. The heat carriers are separated from the hot gases in a cyclone or other separator 4, before re-entering the chamber 1. Solid fuel, which may be the entrained residue of fuel treated in the chamber 1, or liquid or gaseous fuel, may be burnt in the chamber 2. Air is supplied through a conduit 7, and is evenly distributed over the base of the chamber 2 by a grating 8. The carbonisation or gasification process in the chamber 1 may be the production of water-gas from powdered fuel ; the gasification of powdered fuel by air, enriched if desired by oxygen, or by oxygen and steam and/or carbon dioxide ; the dry distillation of powdered fuel or the production of active carbon. Fuel to be degasified may enter the chamber 1 through a conduit 11, and the gas produced may flow out through a conduit 12. Steam, or a mixture of steam and air and /or oxygen, may be introduced through a conduit 13 below a roof 14.

Title: Method of surface hardening of a metal member
IPC: C25D5/02
Filed: 1965-06-14
Abstract: <PICT:1087184/C6-C7/1> The surface of a ductile metal e.g. steel member is hardened while retaining its ductility by depositing a mask on the surface of the member which protects a continuous area defining a plurality of unprotected areas, e.g. spots not more than 0.1 inch diameter, subjecting the member to surface hardening e.g. case-hardening such as carburizing, nitriding or carbonitriding and removing the mask so that the surface contains a plurality of hardened portions e.g. carburized dots 10 supported and separated by a continuous matrix of unhardened member 12a.  For example, a cleaned carbon steel sheet may be first dipped in a photo-resist, a pattern of dots fixed on exposure to mono-chromatic light using an opaque negative pattern and then developed.  After removing unexposed photo-resist, the sheet may be immersed in a copper cyanide plating bath until a copper plate 0.7 mil thick is electro-deposited. After removing the developed dots, the copper clad sheet may be immersed in a cyaniding bath consisting of NaCl, NaCN and BaCO3 at 1450 DEG  F. until carburized to a depth of 0.002 inch.  The copper may be then stripped from the sheet in a CrO3 bath.  The negative pattern may be provided with square or other rectilinear holes to provide the carburized sheet with channels for surface lubricants (see Fig. 3 not shown).  Instead of a cyanide bath, the copper clad sheet may be heated at 950-1050 DEG  F. in an atmosphere consisting of 70% NH3 and 30% N2+H2 for nitriding.
