Patent DK-71491-A (DK)
Inventor: FOUCHE YVON
IPC: H04N5/44
Filed: 1991-04-19
Abstract: A method for transmitting modulated waves simultaneously using a plurality of frequencies comprises successive steps of transmission of symbols for a duration T +  DELTA T, two transmission frequencies being separated by 1/T, T being the useful transmission interval and DELTA T being the transition interval. Synchronisation signals are transmitted enabling, on reception, the sampling of the signal for useful transmission intervals of duration T so as to render orthogonal channels corresponding to the various frequencies. The invention applies to the broadcasting and receiving of radio and television transmissions, to devices for receiving analog and/or digital information, to telephone communications between exchanges, to telephone communications between radio telephones and communication stations, to radio communications between terrestrial stations and satellites, to communications between satellites, to acoustic communications in air and/or in water, and to the construction of local computer networks. The invention is particularly well suited to high fidelity radio transmissions as well as to high definition television (HDTV) and/or digital television. <IMAGE>
Patent GB-454901-A (GB)
Title: Process for the production of red lead
IPC: C01G21/10
Filed: 1936-01-02
Abstract: In the production of red lead from pig lead or lead dust, the lead oxide formed in one furnace is conveyed pneumatically to the red lead furnace through an opening which establishes direct communication between the two furnaces without the intervention of connecting pipes, so that the production of the red lead takes place with the oxide first formed in suspension.  By this means the heating costs of the operation are minimized, both furnaces being insulated against loss of heat.  Conveyance of the oxide from the first furnace to the second may be effected by the suction developed by the dust collector.  The Specification as open to inspection under Sect. 91 comprises also the production of litharge by the two-stage process above described.  This subject-matter does not appear in the Specification as accepted.

Title: Electrophoretic imaging
IPC: G03G17/04
Filed: 1972-01-03
Abstract: 1382341 Electro-photographic apparatus XEROX CORP 3 Jan 1972 [6 Jan 1971] 132/72 Heading G2H To prevent undesirable corona current electrical effects in photo-electrophoretic-copying electrode roller 1 is constructed with a photo-conductive layer 3, over-lying a transparent conductive layer 5, and an internal non-rotating shielded light 7, so that the photo-conductive layer becomes conducting only as it progressively enters lighted zone 9, 10. As a result the field between roller 1 and abutting electrode 13 is switched from a low to a high value at their interface. Preferably the photoconductive layer 3 is overlain by an insulating and opaque layer 4, which prevents stray light from affecting photo-electrophoretic composition 17.

Abstract: 707,057. Valves. VAILLANT, H., [trading as VAILLANT KOMMANDIT GES., J.]. Jan. 3, 1951, No. 212/51. Class 135 A control fitting in gas water heaters has an axially-movable main gas valve manually operated through a pin by a snap-action device. The gas valve 4a, Fig. 1, spring-loaded to open, abuts a rod 6 which abuts a push-rod 7, Fig. 3, carried by a spring-loaded damping cylinder 13 connected by links 22, to a crank 17. The crank handle 18 is snapped from its dotted position, in which the crank is held past its lower dead centre by the spring 15 so that the gas valve is opened, to its full line position in which the spring 15 closes the gas valve. The amount of opening of the valve is adjusted by a spring- loaded plate 25 abutting a flange 8 on the rod 6, the plate being guided by a rod 23 and adjusted by a screw 27. The screw 27 is also moved axially by a collar 30 engaging a rotary cam 31. The gas valve and snap-action device are carried in the horizontal part of a crosscasing 1, and a water deficiency safety gas valve 35 with its water-actuated diaphragm 39 is carried in the vertical part, the rod 6 being slotted to accommodate the gas valve spindle 37. In order to prevent stresses occurring in the pipe connections, a holder 42 supports the gas and water pipes 2, 51, respectively, while the control opening 53 in the casing is closed by a pot 54.

Abstract: 554,606. Hair nets. SHAW & CO., Ltd., R., and SHAW, R. Jan. 7, 1942, Nos. 268 and 13641. [Class 63] [Also in Groups XIV and VIII] Hair nets &c. are produced on a machine, preferably a twist lace machine, in tubular form to which a bag-like shape is imparted. In one method a number of lengths of net are produced across the width of the machine each length being of tubular formation joined at intervals so that each length comprises a series of tubes 1, Fig. 1, enclosed at each end 2, 3. The two faces of the net are joined by the edge warps of each face pillaring with edge bobbins on that face and then tying with the edge bobbins of the other face alternately. Each end 2, 3 of the tube is closed by pillaring 5 and for a short distance a towards one or each end following the pillaring the size of the mesh is reduced. The lengths of tubes are now removed from the machine and secured along the lines A in such a manner that one end is closed by the pillaring 5 and open at the other end. Fig. 3 shows the bag-shaped net. In modification the openings are in the form of slots either in the front or rear face or in the side-edge. These slots 9, Fig. 4, are formed by not typing two adjacent sets of warps by the set of bobbins for a predetermined manner of motions. The lengths of tubes are cut through the pillarings 8 and the reduced mesh c, c<SP>1</SP> adjacent thereto gives the bag-like form. In addition to or in lieu of varying the size of mesh the nets may be positively shaped in manufacture by tying the front and back faces at any or all the groups of positions marked 12 - - 15 in Fig. 6.

Abstract: 660,882. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd., Jan. 5 1949. [Jan. 10, 1948]. No. 289/49. Class 38 (iii). A reversible motor has its field winding F connected in series with its armature A for power operation, a condenser C being connected across the armature to be charged during this period. For dynamic braking, the winding: F is energised from an exciter E which may be driven by the motor and have its field winding f connected across the armature A. When the armature voltage of the motor falls to a predetermined value during braking operation a relay VR is actuated to close contacts IVR, and the condenser discharges through the field. winding f so providing additional excitation for the motor and increased braking-action. Rectifiers R1, R2, prevent the condenser from discharging through the motor armature during the braking-period, these rectifiers being excluded from circuit selectively according to the direction of the motor operation. The power and dynamic braking connections for the motor are effected by electromagnetic contactors under the control of a master switch. Specification 654,375 is referred to.

Filed: 1940-01-11
Abstract: 539,266. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). Jan. 11, 1940, No. 623. [Class 98 (ii)] In making a three-colour positive by direct printing from a coloured dye-image original, compensation is made for faulty colouring due to departure of the dyestuffs used from theoretical requirements by processing the positive copy to colours having absorption maxima different from those required by theory by an amount between 100 to 400 A.U. towards the shorter or longer wave-lengths according as to whether the original used is a positive or a negative. The materials used may be those described as double-layer or triple-layer in Specification 503,752, or those described in Specifications 524,154, 524,554 and 524,555. The processing may be by colour production or colour suppression as defined in Specification 468,560, and in particular by colour development using colour couplers as defined in Specification 478,933 in the emulsions or in the developing baths. In this case, the desired absorption shift may be made by a change of colour coupler, or by a change of the developing agent, or by a combination of both methods. Tables of colour couplers are given together with the absorption maxima of the resulting dyes when using two specified developing agents, and the method of selecting the couplers or the agents is exemplified.
