Filed: 1971-04-19
Abstract: 1291005 Movable storage units BROWN-BUILT Ltd 19 April 1971 [14 April 1970] 26756/71 Heading B8E Wheeled storage units 1-10 are supported on a track 11 extending between end walls 13, 14 and are provided with releasable latches 17- 26 which may be remotely controlled. Intermediate storage units 5, 6 are permanently connected by a double-acting ram 15 which may be beneath, above or at the rear of these units. As shown, the ram is in its extended position. If one of the latches is released and the ram retracted, an aisle 16 between the units 5, 6 will close and an aisle will be made at a position determined by the released catch. The provision of the ram 15 between the units 5, 6 rather than between an end unit 1 or 10 and the adjacent wall 13 or 14 reduces to five the maximum number of units to be moved by the ram. The end units 1, 10 may be latched to the floor instead of to end structures and the ram may be replaced by a reversible chain drive.

Abstract: 1294888 Polyurethanes ATLANTIC RICHFIELD CO 1 Dec 1969 [3 Dec 1968] 58566/69 Headings C3C and C3R [Also in Division C2] Polyurethanes suitably having a weight aver-  age molecular weight of at least 150,000, are prepared by condensation of a polyhydroxyl organic compound with a cyclic nitrile carbonate having the formula wherein R is an organic radical which consists essentially of carbon and hydrogen and is free of reactive hydrogens as determined by the Zerewitinoff test and n is 2, 3 or 4, in the presence of a catalyst combination of (I) a first metal selected from the metals of Groups III to V of the Periodic Table and (II) a second metal selected from the metals of Groups I, II and the iron series of Group VIII of the Periodic Table, the first and second metals being present in non- elemental forms. The polyhydroxyl compound is suitably a polyether or polyester polyol. Suitable cyclic nitrile carbonates are butane-1,4-di- (nitrile carbonate) and benzene-1,4-di-(nitrile carbonate). The catalyst combination may comprise a bi-metallic compound of the two catalytic metals and may be a salt of the formula Mc<SP>+</SP>(MaX)<SP>-</SP>, wherein Ma is the Group III to V metal, Mc is the Group I, II or iron series metal and X is a component which is capable of entering into an interchange reaction with the hydroxyl compound. Preferably X in the above formula is at least partly supplied by -OR groups, R being alkyl, aryl, mixed alkyl-aryl, polyether, polyester or hydrogen. Cellular polyurethanes may be prepared by controlling the reaction to preclude escape of the evolved CO 2  before gelation. Conventional foaming agents may also be added. Numerous examples are given. In a typical example a solution of sodium tertiary butoxide was added to poly- (tetramethylene ether) glycol, followed by dibutyltin oxide and finally butane-1,4-di-(nitrile carbonate).

Abstract: 1295441 Automatic voltage control JOSEPH LUCAS (INDUSTRIES) Ltd 17 March 1970 [31 March 1969] 16674/69 Addition to 1239766 Heading G3R [Also in Division H2] The battery charging system described in parent Specification is modified in that:- (1) the alternator is of single phase, wound field type and the voltage regulator controls the current in the field winding instead of thyristors in the output rectifier. The latter can thus be composed entirely of diodes. or (2) the alternator 8 is of multi-phase permanent magnet type and the warning lamp 31 is held off only by the switching action of the regulator 16. The latter may take the form of an oscillator controlled by a Zener diode responsive to the battery voltage and controlling thyristors 10 in the output rectifier. When the battery voltage exceeds a predetermined value, the Zener diode conducts to stop the oscillator and cause the thyristors 10 to turn off when they are next reversebiassed by the alternator. The lamp 31 is illuminated when the alternator is not producing an output and when the alternator is charging the battery continuously due to the voltage between lines 14,15 being below the predetermined value. In the latter condition the amplitude of the ripple voltage across the lines 14,15 is insufficient to turn off the transistor 19 and hence the lamp 31. When the regulator starts operating however, the amplitude of the ripple voltage increases and the transistor 29 is held off permanently by virtue of the control of the transistors 19, 26 by the respective capacitors 21, 24. The operation of the circuit to maintain the lamp 31 off is explained. If the voltage between the lines 14, 15 rises above a predetermined value set by a Zener diode 33, the latter conducts to turn on the transistor 29 and hence the lamp 31 irrespective of the aforementioned operation of the circuit.

This results in an untufted space occurring between each tufted articles. As shown the machine is producing a tufted article. At the appropriate time the pattern belt 23 causes the photo-electric device 2 to declutch the yarn feed, stop the main motor and actuate valve 6 to cause rod 20 to move leftwards to declutch the needle operating shaft 15 from the main drive and clutch it to a fixed member 14 to hold the needles in a raised position. Shaft 20 also actuates switch 11 to restart the drive motor 3, so that a portion of backing material free of tufts is produced. When the tufts comprise uncut loops a ratchet device 7, 24, 29 is also operated, by the valve 6, to rotate roller 16 and feed enough yarn to form float yarn to extend across the portion free of tufting. This avoids yarn robbing from previously formed tufts. Fabrics. When a sufficient length of backing has been provided with pile loop portions and gaps therebetween the untufted portions are cut away leaving separate rugs, the float yarns lying along the fabric being cut between the pile section to provide decorative fringes or tassel ends.

The member is then recharged, uniformly exposed to one complementary colour, developed with toner of the complementary colour, and the process repeated twice for the other complementary colours, the conditions being such that one complementary colour toner does not deposit on another. The pan-sensitizer may be panchromatically dyed photo-conductive particles or dye particles consisting of a single panchromatic dye or mixture of monochromatic dyes. The developments may be with liquid-suspended toner. Fixing may be effected by heat or solvent vapour treatment of image resin or by presence of filmforming polymer in developer liquid.

Title: Photographic silver halide printing method

Abstract: 1310342 Photographic silver halide printing method KODAK Ltd 10 July 1970 [8 Aug 1969] 39784/69 Heading G2C A method of forming a composite photographic image comprises exposing the sensitive silver halide layer of a silver halide photographic material to form a latent image corresponding to one image component, developing the latent image to a visible image by treating the layer with a silver halide developing solution, treating the layer so as to arrest development of the silver halide therein and then forming a further image component by exposing the layer imagewise to cause printing-out of the undeveloped silver halide. Development may be arrested by treatment of the layer with an acidic aqueous solution, which may contain a halogen acceptor. The acidic aqueous solution may be formed by acidifying a quantity of the silver halide developing solution. The undeveloped silver halide is preferably printed-out in the presence of an aqueous solution of a halogen acceptor which enables the printing-out stage to be carried out uniformly. After development has been arrested the sensitive material may be masked, in the areas that do not require exposure to form a print-out image, with an opaque waterproof material. The layer may be fixed after the formation of the composite image e.g. with a neutral or alkaline fixing solution. The printing-out of the undeveloped silver halide may be monitored photo-electrically using non-actinic radiation. The positioning of the print-out image is made easier by this process since one image component is visible. The process is useful for producing integral masks for adjusting the transmission of the low density areas of line images in gravure cylinder preparation and in producing micro-electronics reticules and certain micro-film frames.
