Abstract: 1,047,352. Beaming machines. MASCHINENFABRIK BENNINGER A.G. Feb. 14,1964 [Feb. 18, 1963], No. 6311/64. Heading D1M. The warp beam brake is supplied with fluid at constant pressure through a regulator valve, and the time taken to bring the beam to rest therefore increases as the beam fills up. In order to bring the presser roll and the measuring roll to rest in the same time, their brakes are supplied by another regulator valve, controlled through linkage by the displacement of the presser roll, so as to reduce the pressure as the winding builds up. The warp beam braking pressure can be altered by manually adjusting its regulator valve; to make a corresponding adjustment to the other regulating valve, the manual control can also be coupled to the linkage to move a pivot point and hence alter the rate at which the braking pressure of the presser and measuring rolls changes.

Abstract: 1,226,882. 882. Cleaning and modifying the surface of metals. DIVERSEY DEVELOPMENT Ltd. April 5, 1968 [May 8, 1967], No. 16504/68. Headings C7E and C7U. A low-expansion alloy of e. g. Ni, Ni-Fe, Fe-Co or Ni-Fe-Co, is finished and desmutted by (a) contacting the surface with a solution at a temperature of 130 to 200‹ F, comprising 1 to 20% by weight of HC1, 1 to 8% HNO 3 , and 0À1 to 20% of one of several condensation products of ethylene oxide with phenol, alkyl phenol, alkyl amine, aliphatic alcohol or polypropylene glycol or polyethoxylated quatemary ammonium salts having 2 to 50 moles of ethylene oxide combined with each mole of quatemary amine, (b) contacting with an aqueous caustre solution containing an alkali metal permanganate, and (c) contacting with an acid, e.g. HCl, HNO 3 , H 2 SO 4  or acetic acid, to remove alkaline film. Phosporic acid may be added in an amount up to 60%. The alloy may be preconditioned as described in Specification 1, 226, 883 using phospheric acid followed by an alkaline solution containing a complex phospate.

Abstract: 1,228,511. Active filters. MARCONI CO. Ltd. 5 Nov., 1969 [14 March, 1969], No. 13421/69. Heading H3U. In a commutated n-path band stop filter, the time period for which each path is selected is less than <SP>1</SP>/ n th of the period of a complete switching cycle, e.g. “n. In order to further improve selectivity, a sample and hold circuit 15, 16 may be connected to the output or, Fig. 18 (not shown), to the input of the n-path filter. The sampling switch 15 is closed for a short time about the centre of the make period of each commutator switch 5 ... 8. In order to remove the higher order stop-band, the filter may be followed by a low-pass filter 14.

Abstract: 1,229,449. Thiocoumarins; pyranthiones. UGINE KUHLMANN. 12 Aug., 1968 [11 Aug., 1967], No. 38409/68. Heading C2C. [Also in Division C4] Compounds of formula wherein n is 0 or 1, A represents the atoms necessary to complete a six-membered ring containing 5 carbon atoms which forms a mono- or part of a polycyclic ring system which may be substituted, R 1  is hydrogen, alkyl or phenyl and R 2  is hydrogen or alkyl or together with R 1  completes a fused benzene ring, are prepared by treating the corresponding oxo compound with phosphorus pentasulphide. Examples relate to the preparation of 4-methyl-2-coumarinthione, 2 - benzo [f] coumarinthione, 6,8 - dimethyl, 4 - methoxy, 6 - methoxy -, 8 - methoxy, 3- methyl, 4-methyl- 6-methoxy-, and 3-phenyl- 2 - thiocoumarin and 8-methoxy- and 3,8-dimethoxy-6H-dibenzo [b, d]-6-pyran-thione. 4- Phenyl-7-methoxy coumarin is prepared by reacting the 7-hydroxy derivative with methyl sulphate. 2,3-Dimethyl-naphtho [b] pyrylium chloroferrate is prepared by reacting 2-hydroxy-1- naphthaldehyde, methylethyl ketone and FeCl 3 / HCI. 2,3,6,8 - Benzopyrylium chloroferrate is obtained similarly.

Abstract: 1,229,577. Rotary wing aircraft. ROLLSROYCE Ltd. 5 July, 1968 [13 July, 1967], No. 32379/67. Headings B7G and B7W. [Also in Division F2] A rotary wing aircraft rotor comprises a hub 13 provided with a plurality of slotted, rotor blades 15, exhaust nozzles 43 and at least two gas turbine engines 16, 17 mounted back to back and vertically above each other within the hub. Each engine 16, 17 is provided in flow series with an air intake 20, two stage, axial flow, low and high compressors 21, 22 driven by low and high pressure turbines 25, 24 respectively and a three stage, radial flow, free turbine 30 driven by engine exhaust gas. At least part of the compressed air delivered by a fan 35 having at least one centrifugal flow stage 33 and driven by turbine 30 is passed via volute 40 to slots 36 to be directed therefrom so that lift is induced by boundary layer blowing. Exhaust gas is directed substantially tangential to the hub by nozzles 43 to provide rotor rotation. Each volute may supply compressed air to two diametrically oppositely disposed rotor blades or a common volute may supply all the blades. The rotation of the rotor may be assisted by supplying compressed air to reaction jets or fan units mounted in the blades.

Abstract: 1,231,322. Activating Cr catalysts. PHILLIPS PETROLEUM CO. 7 Feb., 1969 [8 Feb., 1968], No. 6766/69. Heading B1E. [Also in Division C3] Chromium oxide catalyst compositions containing Cr<SP>6+</SP> are activated by heating the composition to 1500-1800F for at least one minute in contact with a free oxygen-containing gas containing 7-19 mol per cent of free oxygen and the remainder being a gaseous component inert with respect to the catalyst composition. The chromium oxide may be supported on SiO 2 , Al 2 O 3 , ZrO 2 , ThO 2 , or SiO 2 -Al 2 O 3 . The activating gas may contain atomic or molecular oxygen, azone or air. Preferably it contains less than 5ppm. of moisture.
