Abstract: 1,227,460. Electrcgraphic printing. STANDARD TELEPHONES & CABLES Ltd. 9 Oct., 1968, No. 47848/68. Addition to 1,225,823. Heading B6C. [Also in Divisions G2-G3] An electrographic apparatus has a record surface in the form of a drum or band which is electrostatically charged or magnetized to form a pattern representative of information, the drum or band being fed past a combined applicator and scavenging device which transfers powder to and from a powder reservoir. The applicator and scavenging device has a pair of rotatable cones 1 and 5 arranged with one side parallel to a band 9 forming the record surface, at least one cone being magnetized or electrostatically charged and partially submerged in powder in the reservoir. The cone may be a permanent magnet or may be of non-magnetic material covered with a thin sheet of permanently magnetized material. The cone 5 may be of non-magnetic material, but have a roughened surface which removes powder from the record surface. In this case, a stripping blade 11 or brush removes powder from the cone 5. An erase head 16 is provided in advance of recording head 12 to erase the previously recorded magnetic pattern.

Abstract: 1,231,037. Push-pull cables. ETABS DE MACHINES INDUSTRIELLES. 27 Aug., 1968 [11 Sept., 1967], No. 40931/68. Heading B7E. [Also in Divisions B3 and F2] An assembly for controlling a flexible cable comprising two strips 10, 11 twisted together one within the other to helical form consists of means to clamp the guide strip 10 to a fixed abutment 13, 14, 15 (Fig. 2), the ends of the strip 11 being secured to pistons 17 rotatable and axially movable in tubes 16 fixed to the abutments. Each piston 17 is rotatably secured to a sleeve 18 slidable on the respective tube 16. When one sleeve 18 is moved axially, the strip 11 is given combined axial and rotary movement to move the other sleeve 18 axially. In a modification, the guide strip is rotatable but is axially located, and the strip 11 is axially movable but not rotatable. In Fig. 10, the ends of the strip 11 are secured to screws 37 screw-threaded into non-rotatable pistons 32 or slides, the screws having the same pitch as that rotation of the strip 11 during operation causes equal movement of the end screws in their pistons or slides, so that the effective length of the strip is unchanged. The input slide may be a rack bar (39) (Fig. 9, not shown) moved by an input pinion (42). In Fig. 11 (not shown) a rotatable and axially movable hand wheel simultaneously operates two strips (11, 11<SP>1</SP>), relative to respective guide strips (10, 10<SP>1</SP>).

Abstract: 1,231,336. Valves. MESSER GRIESHEIM G.m.b.H. 3 April, 1969 [4 April, 1968], No. 17553/69. Heading F2V. [Also in Divisions F3-F4] A cutting and/or flame scarfing torch (10) has separate valves 22, 23, 24 for the supply of cutting oxygen, heating oxygen and fuel gas respectively and all three valves are operable against respective compression springs 31 by the action of cam surfaces 43, 44, 45 respectively on a slide 39. As shown in Fig. 2, the slide 39 is movable in the direction of arrow 48 to bring cam surfaces 44, 45 into engagement with cross pin 46 on valve tappets 25 thereby forcing a valve plate 28 in each valve 23 or 24 away from a respective valve seat 30; further movement of the slide 39 overcomes a click-stop device and the cam 43 acts to open the valve 22. As seen in Fig. 4 (not shown) a roller (47) is interposed between each cam surface and each cross pin and as seen in Fig. 3 (not shown) the click-stop device comprises a bolt (51) slidably mounted in valve casing 21. In the embodiment of Figs. 5-10 valve tappet parts 74 are operated by a disc-shaped rotary slide 68: the slide 68 has recesses (76), 77, (78) which in conjunction with tappet parts 74 represent closed positions of valves (64, 65, 66), the valves being opening in sequence by rotary movement of slide 68.

In a fluid machine wherein a rotor 2 has a plurality of passages 12, 13 which alternatively communicate with inlet and outlet ports 15, 16 in a non-rotating shaft 1, the shaft is mounted in a fixed housing 3a, 3b, 3c having annular inlet and outlet chambers 24, 25 in constant communication with passages in the shaft leading to the ports 15, 16 and sealed by annular seals 5 which allow limited radial movement of the shaft. A universal joint 23 supports the shaft thereby to allow the radial movement of the shaft. Each annular seal 5 engages on G-ring 11 on the shaft and is disposed in a recess 6 in the housing. The side faces of the seals are in sealing engagement with their respective recesses but radial clearances around the seals accommodate any radial movement of the shaft.

A furnace for simultaneously incinerating refuse and sewage sludge comprises a refuse combustion chamber 8 containing inclined mechanical predrying and combustion grates 2, 3 on which refuse is consumed, and a sewage sludge combustion chamber 9 provided with similar grates 6, 7 for burning out the sludge. The refuse from hopper 20 is dried, ignited and burnt out on the various zones of grates 2 and 3 by a hot or cold undergrate air and/or combustion products blast from duct 13 and chambers 11-11<SP>111</SP>, the incombustible residue falling on to conveyer 14 for discharge. Sewage sludge cakes from receiver 17 are charged on to predrying grate 6 past feed thickness control damper 16, and an air undergrate blast and/or a blast of combustion products from refuse combustion chamber 8 is supplied via chamber 18, to drive off vapour, which with the cooled air and/or combustion gases passes out into predrying chamber 10 via path D. The predried sludge is then ignited and burnt on grate 7 by an air and/or combustion products underblast from chamber 19, the residue from grate 7 falling on to grate 3 in combustion chamber 8 to ensure its complete combustion, before discharge by conveyer 14. Combustion gases from chamber 8 sweep over grate 7 and mingle with the combustion gases therefrom, the mixture then being drawn out through flue 15 at a temperature between 900-1000 C. Vapours from predrying chamber 10 pass into flue 15 through a passage 10a.

A catalyst composition comprising a catalytically active material supported on a carrier is prepared by forming in an aqueous medium a soluble complex derived from a compound of a catalytically active metal and an oxidisable organic complex-forming compound, forming a suspension of carrier particles in this solution, agitating the suspension whilst introducing an oxidation agent under conditions of a predetermined range of pH and temperature, the oxidation reacting with the oxidisable component of the complex homogeneously and sufficiently slowly such that the catalytically active component of the complex precipitates substantially entirely on the suspended carrier particles and separating the thus loaded carrier particles from the suspension. Specified organic complexing agents are: E.D.T.A; nitrilo-triacetic acid; imino-diacetic acid; bis- 2-amino-ethyl-ether-N,N,N',N' tetracetic acid; amino-alcohols, e.g. amino ethyl alcohol; amion acids, e.g. glycine and glutamic acid; and diamines, e.g. ethylene diamine and propylene diamine. Specified oxidation agents are hydrogen peroxide and salts of halogen oxyacids, e.g. sodium hypochlorite. Metal components specified are iron, copper and silver, the preferred carrier material being silica. The catalyst may be further treated if required, eg. by calcination or reduction of a catalytic component to the corresponding metal. In the Examples- (i) an iron (III) oxide or silica catalyst' contained some sodium chloride because of the method of preparation and (ii) a silver or silica catalyst contained some carbon originating from the complexing agent.

A carrier gas flow control system which enables different constant flow rates to pass through gas chromatography column 3 and detector 4, e.g. a flame ionization detector, comprises gas flow restrictor 1 and flow regulator 2 with their low pressure and high pressure ends connected in parallel as shown, the low pressure end being connected through adjustable needle valve 5 to a point between column 3 and detector 4. With valve 5 closed a common constant flow rate is established in column 3 and detector 4; with valve 5 open to a particular setting, the flow through the by-pass is maintained at a constant pressure by regulator 2, and since the total pressure applied is constant, the flows through column 3 and detector 4 will both be constant though of different values. In modifications (see Figs. 2-4, not shown), the flow rates through the by-pass may be pre-set to particular values; the flow rate through the column 3 may be varied while maintaining the flow rate through detector 4 constant for any particular setting and automatic operation accomplished by governing valve 5 with a servo-amplifier controlled by a flow meter upstream of the column 3.
