Abstract: 1531131 Foam laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 11 March 1976 [18 April 1975] 16065/75 Heading B5N A laminate having a foam core sandwiched between and bonded to two outer facings is produced by applying, e.g. by spraying, to a lower facing 1, e.g. of paper, a liquid foamforming composition 11, e.g. a polyurethane, bringing an upper facing 3, e.g. of paper, into contact with the foam-forming composition at a position where substantially no expansion has occurred and maintaining the upper facing in contact with the foam throughout the zone in which expansion takes place by applying gaseous pressure to the upper surface of the upper facing and then allowing the expanded foam to cure. Gaseous pressure may be applied using air heated to 50-120C. The upper facing may be applied to the foam-forming composition using a pair of nip rolls, one below the lower facing and one above the upper facing. Alternatively, the lower roll may be replaced by a fixed bar or plate, and the upper roll replaced by a resiliently mounted bar. The expansion zone may comprise fixed platens 6 heated by electric blankets 7, a vacuum being obtained at the lower facing surface by means of a vacuum box 8, connected to a vacuum pump so that gas is drawn through holes in the surfaces of platens 6. The means for supplying gaseous pressure may consist of one or more hoods 10 extending in total over substantially the whole of the area of the laminate in the foam expansion zone and having perforated bases, the flow of gas to each hood being controlled by valves 13. Each hood is freely rotatable about axis BB and is freely movable vertically under the influence of increased gas pressure. The hoods may be weighted or counter-balanced to produce the desired loading by air cylinders 12. The gas flow rate and pressure may be chosen so that each hood floats on a gas cushion on top of the upper facing surface, the major portion of the gas exiting along the ends of the hoods. Flexible skirts, or linkages may be provided between adjacent hoods.

IPC: G06F12/04
Filed: 1969-03-28
Abstract: 1,242,651. Shift in computers. BURROUGHS CORP. 28 March, 1969 [29 March, 1968], No. 16272/69. Heading G4A. An offset network laterally displaces parallel data. In a computer any of three registers can be gated, parallel by bit, to an offset network feeding a masking network feeding any one of the three registers. The offset network consists of a matrix of ANDs, feeding ORs, to ring-shift the incoming data by any number of bit positions 0 to m-1 (there being m bits in each register) according to which one of m output leads of an offset is energized. The masking network includes a comparator comparing the contents of a top-of-aperture register and top-ofmask register which have a 1 in each bit position from the right up to and including the leftmost bit of desired aperture and the leftmost bit of the mask (which is those bit positions not in the aperture) at the other end of the aperture, respectively. Logic circuits respond to the top-of-aperture and top-of-mask registers and to signals from the comparator indicating whether the leftmost bit of the aperture is to left or right of the leftmost bit of the mask referred to, to gate out of the masking network only those bits from the offset network which lie within the aperture. The aperture consists of all bits starting from and including the leftmost bit of the aperture going to the right (in an end-around manner if necessary) up to but not including the leftmost bit of the mask referred to, so according to the relative order of the two " leftmost bits," the aperture can be in one piece bracketed by mask portions or be the complement of such a piece. The arrangement can be used to shift a field lying within three consecutive memory words (and crossing both word boundaries) to a different position in three other consecutive memory words, a control circuit being disclosed to load the offset, top-of-aperture and top-of-mask registers with the appropriate numbers at the appropriate times and access the memory appropriately, under control of an instruction which specifies the addresses of the first words in the two sets of memory words involved, the desired start and finish bit positions of the field (in its final position) and the start bit position of the field in its initial position.

Title: Rail arrangement for the permanent way of railways or the guide rails of endless conveyors
IPC: B65G21/22
Filed: 1951-07-10
Abstract: 707,465. Endless conveyers; railway rail joints. GREBE, K. July 10, 1951 [July 10, 1950], No. 16350/51. Classes 78 (1) and 104 (2) A rail joint including a section, interposed between the rail ends which is more flexible than the rails and forms with the rails a continous runway for wheels, conveyer rollers, &c. has its flexible section or sections formed of assemblies of individual spring elements alternately curved in opposite directions and so arranged on elements bridging the space between consecutive rails that, without undoing the coupling, the flexible sections can be bent both horizontally and vertically and can be twisted and lengthened or shortened. As shown, the rails for supporting the two side rollers and the bottom roller of an endless travelling structure comprising wheeled trolleys are formed in sections which are joined by one or a number of the assemblies 27, 31 of springy members. In one form, Fig. 8, the springy members are each formed to the cross-section of a rail and are threaded on one or more bolts 26 such that they are alternatively arched one way and the other. The members are held in place and may be pretensioned by threaded collars on the ends of the bolts and the assemblies are loosely fitted by means of the collars within apertures in plates 25 fitted to the ends of the rails. To prevent undue lateral stress on the assemblies, and to prevent the collars from coming out of the apertures in plates 25, the structure sections supporting the rail section are coupled by loose bolts 28. The bolts 26 are preferably capable of bending resiliently so that smooth curves may result at the joints of the rails. In a second form, Fig. 5, the assembly 31 extends across all the rails and consists of springy members threaded on bolts 33, the members being arched alternatively one way and the other between the bolts 33. One end of each bolt 33 is anchored by a nut 34 on a plate 35 fitted to the rails of one section while the other end is passed through holes in a plate 35<SP>1</SP> fitted to the rails of the other section and prevented from withdrawal therefrom by a spring clamp 39 which is forced over the tapered head 36 on the end of the bolt into a groove in the bolt behind the head, the two clamps 39 being secured to members 40 welded between the rails of said other section. In assembly, the springy members are threaded against a collar on each bolt 33 and the nuts 34 are tightened to pre-tension the assembly. Each clamp 39 may be opened to assist in forcing it over the head 36 of the corresponding bolt 33 by a cam provided with a spindle which is inserted in a bore in the head of the bolt, and turned by a suitable lever. Specification 363,538 is referred to.

Title: Improved process for the treatment of gases produced by the carbonisation of coal
IPC: C10K1/34
Filed: 1942-11-24
Abstract: 563,350. Extracting sulphur compounds from coal gas. GAS RESEARCH BOARD, and KEY, A. Nov. 24, 1942, No. 16658. [Class 55 (ii)] In the extraction of sulphur compounds from coal gas after removal of most of the hydrogen sulphide, which includes the conversion of organic sulphur into hydrogen sulphide, the catalyst used for this conversion is poisoned by certain hydrocarbons containing triple bonds, especially acetylene, and these hydrocarbons are converted by subjecting the gases at a temperature of 250‹-350‹ C. to a hydrogena. tion catalyst, such as a sulphide of molybdenum or nickel, into olefinic or saturated hydrocarbons. The gas may be then treated by the process of Specification 561,679 in which it is subjected to a treatment by chromium or an oxide or sulphide of chromium alone or mixed with copper or an oxide or sulphide of copper to convert organic sulphur compounds into hydrogen sulphide. Alternatively, this latter treatment may be replaced by one including heating of the gas to 250‹ to 350‹ C. and subjecting the gas to a substance such as oxide of iron or copper which not only converts organic sulphur compounds into hydrogen sulphide but also removes the hydrogen sulphide. In another modification, as it is found that the hydrogenation catalyst is capable of converting organic sulphur compounds into hydrogen sulphide to a considerable degree, the subsequent treatment may be omitted. The nickel sulphide catalyst may be prepared by impregnating a porous support of silica or alumina with a nickel salt in solution, heating the mass to form the oxide which is then heated in hydrogen to yield metallic nickel which is treated with hydrogen sulphide.
