Patent GB-932501-A (GB)
Title: Production of aliphatic alcohols
Filed: 1961-03-28
Abstract: An aliphatic alcohol, other than isopropyl alcohol, is prepared by partially oxidising a trialkyl aluminium with a gas containing molecular oxygen, there being added before the conclusion of the oxidation between 0,05 and 0,5 mole of aluminium isopropoxide per mole of trialkylaluminium and hydrolysing the product.  The hydrolysis is preferably carried out by treatment with steam or dilute acid.  Suitable trialkylaluminiums are those, for example, in which the alkyl groups contain 1-20 carbon atoms.  The oxidising gas may be air, air enriched with oxygen or pure oxygen. Preferably the aluminium isopropoxide should be added to the mixture when not more than 2/3 of the trialkylaluminium has been oxidised.  The process is preferably carried out at 50-90 DEG C. Specifications 794,359, 808,055, 834,379, 835,555, 836,792, 837,119 and 857,681 are referred to.

Abstract: 1,176,498. Spray-producers. ASAHI BREWERIES CO. Ltd. 10 March, 1967 [1 June, 1966], No. 11417/67. Heading B2F. A reaction jet spray producer suitable for cleaning containers or sprinkling insecticide comprises a liquid ejecting unit provided with a plurality of perforated branch pipes and rotatably mounted on a liquid supply pipe 16, and a speed control device including a tube 7 which is angularly adjustable with respect to the branch tube on which it is mounted. A jet orifice 8 in the tube is aligned with bores 14, 15 in members 17, 4, which are adapted to mount the tube on the said branch pipe, and with an opening 3 in the pipe. The unit 1 is rotated by jet reaction from the orifice 8 and a ball valve 9 rises within each tube 7 towards its closed end until the ball blocks the respective orifice 8, thus causing the unit to slow down. The ball then rolls towards the open end of its tube under gravity. The required speed of rotation may be selected by adjusting the angle of the tube. Two, three or even more branch pipes may be symmetrically disposed around the axis of rotation of the unit and one or all of the pipes may be provided with a speed control device. A spring may be located in each tube between a stop member 10 and the valve. The ends of the pipes may discharge upwardly through nozzles.

[Class 37] Insulation-breakdowns on all-insulated control and protective circuits are indicated by an arrangement similar in some ways to that of Specification 430,763, [Group XXXV], in which one of the main conductors is connected to earth through a circuit containing an auxiliary source and relay, together with a current-limiting resistance. The arrangement is operative even when insulation deteriorates, equally on both conductors. In a D.C. circuit of 110 volts, the + conductor 1 is connected to the sheath 3 through a battery B of 30 volts arranged in the same sense as the main voltage. The combined resistance of relay T and resistor R may be 6,000 and if relay T requires 5 milliamps to operate, it will detect a dead earth on conductor 1 and a fall in insulation resistance of conductor 2 with or without conductor 1 to 22,000 ohms, or with smaller operating current it will detect a higher insulation resistance on conductor 1 alone. A rectifier 4 is included in controlling A.C. circuits.

Abstract: 1,261,642. Treating plastics surfaces. INTERNATIONAL BUSINESS MACHINES CORP. 5 March, 1969 [6 March, 1968], No. 11663/69. Heading B2E. [Also in Division B5] The surface of a plastics material is treated to improve its adhesion to metals applied by electroless plating techniques by treating the plastics surface with a first liquid which partially dissolves the surface and whilst the surface is still wet treating it with a second liquid which is miscible with the first but which is a non-solvent for the plastics material, thereby depositing a matt of the plastics on the surface; drying to remove the liquids; rendering the surface wettable by water e.g. by acid conditioning which may be followed by alkaline cleansing step and a sensitisation step. The plastics may be polysulphones, polyesters polyphenols or polyvinyl chloride. In an embodiment, polysulphone (made from SO 2  and 1-butene) is immersed in methylene chloride and then in a ketone (e.g. (CH 3 ) 2  CO, CH 3 .CO.C 2 H 5 ). The material is dried in air for 30 minutes and then etched in an H 2 SO 4 / chromic acid composition, rinsed in water and then immersed in an alkaline cleanser, washed and then sensitised by treatment in SnCl 2  and PdCl 2  before immersion in an electroless plating bath. The deposited metal film may be thickened by electroplating.

One or more roller brushes 21 rotate, in either direction, such that the tips of their bristles pass randomly between the prongs to brush, and apply randomly directed forces to, the film. The peripheral linear speed of each roller brush ispreferably greater or less than that of the piercing roll. The prongs may be metal needles, or filet card or metallic card clothing. The bristles may be of nylon. Each roller brush may be vibrated, or reciprocated axially.

[Class 20 (iii).] A protective device for a window A, Fig. 1, comprises a hinged steel or like frame B the bars of which coincide with the glazing bars or like elements of the window structure, and the hinges C and fastening device of which are shrouded in order to prevent any unauthorized interference therewith. In the form shown, the fixed leaf of each hinge C is secured to the underside of a bar E, Fig. 4, which extends along one vertical edge of the fixed window frame A<1> to which it is secured by bolts F. The casement frame A is hinged at D. Recesses G are provided in the bar E and/or the frame B to house the pintles of the hinges C, D, in such a manner as to prevent their removal. Bosses I, Fig. 2, are carried by the frame B, each of which is adapted to enter a recess K in the fixed frame A<1>. The frame B is held in the closed position by bolts M each of which is inserted through hole L from the inner side of the window and engages with a screw-threaded hole S in the boss. When the bolt is screwed home, its head N rests within a recess K ; the bolt-head is preferably of an unusual shape, thus necessitating the employment of a special box spanner O to turn it. Clips H fastened to the casement frame and embracing the frame B, connect the frames and at the same time permit any slight relative movement during the opening and closing operations. Alternatively, a pin-andslot connection is employed. For double casements, the free edge of one frame B overlaps the second frame, one frame being joggled so that the outer surfaces are flush.

Title: Process for producing float glass
IPC: C03B25/08
Filed: 1965-03-19
Abstract: In a process for the production of float glass a gas is discharged against the annealing lehr conveying rolls for a sufficient length of time to condition the rolls so as to prevent them from becoming encrusted and thus damaging the glass ribbon. A glass ribbon 14 (Fig. 1, not shown) is lifted off the float bath 12 on to a pair of rollers 16, 18 in a chamber 48 and is then transferred on to the main lehr rolls 22-28. Spring-loaded carbon pads 44, 46 hone the surfaces of rolls 16 and 18.  Drapes 32-42 suspending from the lehr roof substantially eliminate any ingress of air into the lehr but some carryover from the float bath exists which is rich in tin and attacks the stainless steel rolls 22-28. To prevent this a gas, e.g. steam, is periodically directed against the first thirteen rolls and gives them an oxidized appearance. The steam is passed through a V-shaped nozzle 50 (Fig. 2, not shown) having holes in each of its two legs at approximately 45 degrees to the horizontal.  The gas pressure is preferably above 25 p.s.i. and at a temperature of more than 200 DEG F., e.g. steam at 365 DEG  F. and 125 p.s.i.  The gas must contain oxygen and moisture.

Alternatively, the central portion may have ribs of densely compacted fibres. Side tab portions 16 for securing the mask to the head are also densely compacted. The mask is moulded at a temperature of 290-300‹ F. from a fibrous mass or web comprising 55-90% of non-thermoplastic fibres, e.g. viscose rayon or cotton, and 10-45% thermoplastic fibres, e.g. copolymer of vinyl chloride and vinyl acetate. The mask is sprayed with polyvinyl alcohol, methyl cellulose, hydroxyethyl cellulose, polyacrylates, polyamides or polyesters to prevent fluffing in use and to preserve its porosity during sterilization.
