Abstract: 1426635 Catalytic composition for polymerization SNAMPROGETTI SpA 23 Nov 1973 [29 Nov 1972] 54614/73 Heading C3P Unsaturated hydrocarbon compounds are polymerized in the presence of a catalytic composition comprising (a) a uranium compound of the formula UX n-m Y m  where Y is a halide or pseudohalide, X is an alkoxy or amino group, n is 4 or 5, and m is 0 to n, with the proviso that when Y is a halide, n exceeds m, (b) a reducing hydride or alkyl compound of aluminium and (c) a Lewis acid. The catalysts are particularly useful for homo- or copolymerization of mono- and diolefins; they may be formed in the presence of part of the diolefin monomer and may be "aged" in the presence or absence thereof. The catalytic residues may be removed by the usual alcohol treatment or by centrifuging to remove the heavy metal residues. Examples relate to the homopolymerization of butadiene, isoprene, pentadiene-1,3 (75% transisomer), 2,3-dimethylbutadiene and ethylene and to the copolymerization of butadiene/isoprene, butadiene/ pentadiene-1,3, ethylene/butadiene and ethylene/isoprene using catalysts typcially comprising (a) U(OMe) 4 , U(OMe) 3 Cl, U(NEt 2 ) 4 , U(OiBu) 5  and U(OC 8 H 17 ) 4 ; (b) AlEt 3  and Et 2 AlH, and (c) AlBr 3 , TiCl 4  and EtAlCl 2 .

Title: Improvements in or relating to fire-detection apparatus

Abstract: 1,222,351. Photo-electric smoke detectors. D.C. ADAMS. Feb. 29, 1968 [Dec. 7, 1966], No. 54833/68. Heading G1A. [Also in Division G4N] A smoke sensing device comprises two photodetectors one of which is arranged to receive light directly from a source through a smoke detecting zone while the other is arranged to receive light diffused by the smoke, a lamp,failure alarm responsive to the absence of current through the source and a transistor amplifier. The two detectors may be arranged in the two arm of a potentiometer network connected across a voltage source. As shown a first photo-resistor P1 is arranged to receive light transmitted through the smoke detecting zone 1 fron a lamp LP1 and a second photo-resistor P2 is arranged to receive light diffused by smoke in the zone. The two photo-resistors are connected in series with an adjustment resistor R1 across power supply lines 10 and 13. The voltage on these lines which supply a number of similar devices is stabilized at each device by a feed resistor R4 and a Zener diode ZD. A transistor T is arranged to amplify the differential output to the two photo-resistors one of which responds mainly to white smoke while the other responds mainly to black smoke, a thermistor R3 being included to compensate for temperature changes. The output of the transistor is again amplified and operates an alarm relay RW2 closing normally open contacts 15 if the smoke density reaches adetermined level. Closure of the contacts 15 energizes an alarm relay AR at the central station and lights a local indicator lamp LP2. A normally energized relay RW1 is series with the lamp LP1 releases if this lamp fails thus operating contacts 16 and energizing a lamp failure relay FR at the central station. The lamp failure relay has normally closed contacts 18 in series with the alarm relay which is slow to operate and thus disables the alarm relay in event of lamp failure. In a modification the contacts 16 are in series with the contacts 15. In a further modified device the lamp LP1 additionally functions as the feed resistor R4. In another modification the two photo-resistors are separately connected each in series with a resistor as separate potential dividers across the voltage source and the two outputs are applied to the base of the transistor via diodes. In a yet further form similar to that last described the diodes are replaced by further transistors functioning as amplifiers.

Abstract: 1,237,490. Extrusion laminating. CADILLAC PRODUCTS Inc. 12 Nov., 1969 [18 Nov., 1968], No. 55458/69. Heading B5N. A laminate is formed from at least an extruded plastics layer 30, a layer 40 and a further plastics layer 44, which is dissimilar to layer 40 and whose surface has been treated by oxidation, by flame or electronically to improve adhesion, by simultaneously contacting the layers between oppositely-rotating rolls 14, 16, bonding being achieved by the heat of the extrudate 30. A substrate layer 22 may be included. The nip roller 16 should have a resilient surface, and the chill roller 14 and back-up roller 18 should be fluid-cooled. More than one roller assembly may be necessary for complete bonding. The arrangement shown may be reversed, with layer 30 being extruded into contact with the chill roller 14 and layers 40, 44 being fed over the nip roller 16. Layer 30 should be extruded at 200- 700‹ F., preferably 590-620‹ F., and the chill roller 14 should be below 120‹ F. The substrate 22 may be of paper, cloth, metal foil, polyethylene terephthalate, regenerated cellulose, single-faced corrugated paperboard, plastics foil, or expanded plastics, or may be a supported film of cellulose acetate, polyethylene terephthalate, vinyl chloride-vinyl acetate copolymer or polyvinyl butyral. The extrudate 30 is preferably polyethylene, but may be another polyolefin, vinyl polymer or hot-melt adhesive, and may be expanded. The layer 40 is preferably metal, but may be paper, cloth, rubber, regenerated cellulose or polyethylene terephthalate. The plastics layer 44 is preferably a polyolefin film, e.g. polyethylene, but may be polyethylene terephthalate, cellulose ester, regenerated cellulose or a vinyl polymer, and may be foamed, or may be a supported film or a laminate. Further layers may be present, in which case the other surface of layer 44 should be treated to improve adhesion. In a modification a laminate is formed from a temperature-sensitive substrate, a plastics layer and a hot extrudate whose temperature is below 590‹ F., with the substrate in contact with the nip roller 16 and the extrudate in contact with the chill roller 14; the surface of the plastics layer is treated as above to improve adhesion. The extrudate may be polyethylene, ethylenevinyl acetate copolymer, vinyl chloride-vinyl acetate copolymer, polystyrene or an acrylate. The plastics layer may be surface-oxidized polyethylene and the substrate may be regenerated cellulose, vinyl polymer or polyethylene terephthalate.

Abstract: 1361919 Hydraulic control circuits BBC BROWN BOVERI & CO Ltd 11 Dec 1972 [13 Dec 1971] 57011/72 Heading F1P With a reversing valve 11, Fig. 1, in the position shown, both sides 3, 8 of a piston 2 are connected via passages 7, 9 to an accumulator 4 and the piston moves to the position shown. The valve 11 is moved to the position shown when a chamber 15 is pressurized. This occurs when a valve 18 is opened to move a valve 14 to the position shown. When a valve 21 is opened the chamber 15 is depressurized by connecting it to a reservoir 6 and the spool of valve 14 moves upwards. Piston 13 now moves the valve 11 to the left to close the connection between passages 7 and 9 and to connect the chamber 8 to the reservoir 6. Since the chamber 3 is still under pressure the piston 2 moves to the right. Fig. 2 shows a construction of the piston 11 in which movements are damped by throttling ports 27. A spring-loaded throttling device 28 controls the flow of fluid to the reservoir. Valve seats 22, 23 are resiliently mounted and their movements are damped by oilfilled spaces 32 which are filled through ports 33. Fig. 3 shows a construction of the piston 2 in which shoulders 2c damp movement at the end of the stroke by co-operating with an annular space 37. In the opposite direction damping is effected by an annular space 38, Fig. 4 (not shown).
