Abstract: Various amount ratios are used in this continuous process, the total H2S-containing gas being partially oxidised in the presence of significant amounts of the SO2-containing gas in a 1st reaction zone at 800 - 1400 DEG C with an O2-containing gas, while the residual SO2-containing gas is partially reduced in the presence of a reducing gas in a 2nd zone at 1000 - 1500 DEG C and then the mixture from both zones with a now nearly stoichiometric H2S : SO2 ratio being reacted in a 3rd zone at 800 - 1300 DEG C without further direct heat addition to give sulphur, which is separated by condensation, and to give a gas mixture which can be processed further in a conventional Claus plant.

Abstract: A component digital video signal is encoded such that first and second colour components (CB, CR) are modulated on the lower sideband of a carrier at the Nyquist frequency of the luminance component (Y). The encoding method involves alternately adding and subtracting the luminance and colour component signals (Y + C, Y - C, Y + C, Y - C, (etc)) and changing the phase relationship between this addition and subtraction for the first and second colour components (DB, CR) every field, so that in each alternate field the addition and subtraction operations are in phase for both colour components (CB, CR) and in every other field, the operations are out of phase. Upon decoding, the encoded video signal is comb filtered to recover the luminance component (Y) and colour components (CB, CR), and the correct phase for the colour components (CB, CR) is restored by a phase alternation operation which is inverse to that applied during encoding.

Abstract: A web (110) of two-wide potentially separate business forms adjoined in series by transverse perforation lines (126) is provided, with a respective longitudinal row of sprocket holes (120,122) bordering each edge. Printing is placed on left and/or right portions of at least one face of the web, at least one portion of one face being variably printed. At the appropriate stages in relation to the printing, the web is severed along a medial longitudinal line (124) and the resulting two portions (146,154) are moved laterally, without rotation, towards superimposition, and each resulting one-wide, multiple ply potentially separate business form is marginally sealed, e.g. by activation of a pre-applied ring of adhesive (144).

Abstract: A vend basket for a coin operated vending machine includes a first roller (68) whose axis is parallel to the rotational axis of rollable products, such as bottles or cans, and is set back from the front wall (64) of the basket by a distance greater than the diameter of the rollable product but less than twice the diameter so that only one product can fit and pass between the front wall and roller. The roller is also spaced above the bottom wall (61) of the basket so that two rows of products can fit and pass under the roller. A second roller (71) whose rotational axis is also parallel to the rotational axis of the rollable products is located in front of the first roller adjacent the front wall directly above a dispensing lid (11). The distance between the first and second rollers is such that only one article at a time can pass therebetween to a cradle (37) formed in the dispensing lid. Such a structure permits a greater number of movable products to be located in the basket. Furthermore, the rollers prevent the products from becoming jammed during a dispensing operation of the vending machine.

Abstract: The present invention provides a circuit arrangement for processing colour television signals. This circuit arrangement comprises a first differential switching circuit (Q814, Q815) into which a delayed signal is supplied via time delay means having one horizontal line and from which said delayed signal is delivered under the control of a first control signal, and a second differential switching circuit (Q820, Q821) into which an undelayed signal is supplied and from which, under the control of a second control signal, one signal whose phase is in phase with that of said undelayed signal and another signal whose phase is opposite to that of said undelayed signal are delivered. In a signal matrix circuit said signals output from said first and second differential switching circuits (Q814, Q815; Q820, Q821), are vector-summarized and are performed in a vector-subtraction when processing said first composite colour signal, and from which results of said vector calculations are delivered through a first and second output terminals. A system switch control circuit (79) generates a third control signal by kwhich the matrix opesration of said signal matrix circuit can be interrupted when processing said second composite colour signal, and a fourth control signal by which switching states of said first and second differential switching circuits can be changed over, so that said delayed signal is blocked at the output terminal of said first differential switching circuit and so that the supplying of the inverted signal of said second differential switching circuit into said signal matrix circuit is blocked. Control means control gains of said first and second differential switching cir­cuits under the control of the outputs from said system switch control circuit by changing over resistor networks constituting said signal matrix circuit under the control of the outputs from said system switch control circuit.

Abstract: A group of hydro-monobenzoporphyrins "green porphyrins" (Gp) having absorption maxima in the range of 670-720 nanometers is useful in treating disorders which are subject to hematoporphyrin derivative (HPD) treatment in the presence of light. The use of the Gp of the invention permits the irradiation to comprise wavelengths other than those absorbed by blood. The Gp of the invention may also be conjugated to receptor ligands or to specific immunoglobulins or fragments thereof to target specific tissues or cells for the radiation treatment. Use of these materials permits lower levels of drug to be used, thus preventing side reactions which might destroy normal tissues.
