Abstract: 1511911 Removing sulphur oxides EXXON RESEARCH & ENG CO 2 May 1975 [22 July 1974] 18453/75 Heading C1A Sulphur oxides are removed from a gas mixture, e.g. flue gas by contact with a sorbent comprising (a) copper and/or copper oxide, (b) a carrier comprising a major proportion of Al 2 O 3  and which has not been exposed to a temperature above 1400‹ F. and (c) MgO at least a part of which is on the carrier surface. The sorbent may be formed by impregnating the carrier with Mg salt, heating to convert to MgO, filling the pores of the material with C 5 -C 10  alkanol, contacting with Cu salt solution and again heating. Alternatively the pores of the Al 2 O 3  may be liquid-filled before contact with mixed Mg and Cu salt solution. In examples, SO 2  is separated from N 2  containing also O 2  and H 2 O.

[Also in Group VIII] The joints between sewage pipes are packed with a material made by impregnating an elastic material, having a foam structure, with a bitumen, which is solid and non-tacky at room temperatures, in such a manner that the walls of the pores or cells are coated with the bitumen but not filled by it and a product which is still elastic is obtained. Asphaltic bitumen as a solution or emulsion for example with bentonite as emulsifier may be used to impregnate the foamed material, e.g. viscose, polyurethane or foamed polyvinyl plastic and the material may be led through a bath of the impregnant, and then through squeezing rollers and dried.

A starter bar head has a part 2 which is pivoted on a pin 6 to form jaws with the main part and which has concave surfaces for coaction with a rotatable locking pin 10 so that it can be locked by one surface, as shown, in the open position to release an expendable keying piece 3 which remains in the cast strand 7 when the starter bar is removed. The pin 10 coacts with the other concave surface when the jaws are locked on to a bead or flange of the keying piece 3. A longitudinal wedge may replace the rotatable pin 10. The keying piece 3 consists of a piece of a rolled section such as a cableway suspension rail as shown, or a railway rail, Fig. 4 (not shown). Several pieces may be used with each head. The jaws may be opened automatically by rams. A layer of asbestos (8) and scrap for cooling prevents adhesion of the cast metal on the jaws. The head may be releasably coupled to an articulated starter bar by a similar jaw arrangement so that different sized heads may be selected for use.

Abstract: 498,413. Valve generating circuits. RADIOAKT.-GES. D. S. LOEWE. July 8, 1937, No. 19025. Convention date, July 8, 1936. [Class 40 (v)] Frequency reduction is effected by a chain of multi-grid valves with adjustable coupling between them, the valves oscillating without interaction when the coupling is at the zero point. Each valve of the chain of frequencyreducers has its anode coil 12b coupled to a tuned grid circuit 3, 12a, the natural frequency of which is adjusted by a resistance 16. The cathode leads include bias resistances 4 shunted by condensers 5, and the screen grids 8 are biassed by potentiometers 19, 20 and are shunted to earth by condensers 21. Each stage applies synchronizing impulses to the succeeding stage by means of a slider on a resistance 14<1> in the anode circuit of one valve 2 connected to the suppressor grid 9 of the next valve 1. The connection includes a block condenser 15<1> and a series resistance 10 to reduce grid current, and the mean voltage on the grid 9 is held to that of the cathode by a high resistance 11. In a modification, Fig. 2 (not shown), the synchronizing impulses are applied from a slider on a resistance connected between the coil 12b<1> and the cathode of the valve 1. A condenser is connected between the coil 12b<1> and the anode so that anode direct current of the first valve. 1 is diverted from the coil and is fed through a resistance in the manner shown in Fig. 1 for the second valve. Specification 475,595 is referred to.

Abstract: 1391477 Sawtooth wave generating circuits; synchronizing television time bars PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 April 1972 [28 April 1971] 19096/72 Headings H3A and H3T A sawtooth generator comprises means 12 for charging a capacitor, means 8 for discharging the capacitor in response to amplitude limited pulses derived from the flyback pulse C of a television line time-base and means for controlling the charge current to maintain the mean amplitude of sawtooth waves constant. The circuit described is for generating the comparison wave for the AFC circuit of the line time-base and it is explained that clipping the flyback pulse and stabilizing the mean level removes jitter due to flyback pulse height and width variations. The mean level is controlled in the circuit shown by comparing a reference voltage at the base of transistor 14 with the mean level of the wave desired from the wave by a filter 19-22. The resulting voltage across 13 controls the charging transistor 12. The flyback pulse may also be applied to a transistor 26 to cut-off the charging current during the flyback.
