Title: Connection of tubes and coupling members and to coupling members therefor
IPC: F16B7/04
Filed: 1974-07-17
Abstract: 1481801 Tube couplings RYDERS (LANCASHIRE) Ltd 17 July 1974 [17 July 1973] 33904/73 Headings F2G and F2M Two tubes 22, 23 are coupled by a coupling member comprising two cylinders 19 of for example aluminium interconnected by screw - threaded stud 21 extending through disc 20 and screwed into screwthreaded bores in respective cylinders 19. Each cylinder 19 has at its free end a resilient element 15 e.g. of rubber which has a slightly larger diameter than that of cylinder 19, a steel washer 16 whose diameter equals that of cylinder 19 and a bolt 17 which passes through washer 16 and element 15 and screws loosely into the bore of cylinder 19. Element 15 has a centre hole of diameter less than that of the shank of bolt 17 so that element 15 frictionally grips bolt 17. Tubes 22, 23 are coupled by fitting one on to each end of the coupling member until they abut disc 20 and then rotating tube 23 clockwise with respect to tube 22, as viewed in the direction of arrow B, which as a result of the frictional engagement between tubes 22, 23 and elements 15, and between elements 15 and bolts 17 rotates tube 23 and thus bolts 17 are screwed into cylinders 19 axially compressing elements 15 between washer 16 and the end of cylinder 19 causing the elements 15 to expand radially outwards to grip tubes 22, 23 and hold them against axial movement relative to the coupling. The tubes are released by relative rotation in the opposite direction. In another embodiment a tube is coupled to a plate by a coupling member having a single cylinder bolted to the plate at one end and having a resilient element and washer bolted loosely to the other end, the tube being pushed on to the coupling member and rotated thus screwing the bolt carrying the washer and the resilient element into the cylinder and axially compressing the resilient element causing it to expand radially against the inner surface of the tube preventing axial movement of the tube relative to the coupling. The couplings may be used in the construction of hand rails.

Title: Manufacture of compounds of the anthraquinone series
IPC: C09B1/28
Filed: 1937-12-08
Abstract: 507,206. Dyes. OLPIN, H. C., and TOPHAM, C. F. Dec. 8, 1937, No. 33919. [Class 2 (iii)] Leuco:1.4-di(monosubstituted-amino) anthraquinones in which the substituents in the two. amino groups differ are made by reacting with two different primary amines together or in succession a leuco-1-amino-4-hydroxyanthraquinone in the form of the reaction mixture in which it has been prepared by the action of ammonia on a 1.4-dihydroxyanthraquinone free from amino substituents, the ammonia having been used in excess of that theoretically, required to replace one hydroxy group by an amino group (see Specification 507,065). The leuco compounds so obtained may be oxidized to the parent materials. The substituents in the amino groups may be alkyl; hydroxyalkyl, aryl, cycloalkyl or aralkyl, e.g. methyl, ethyl, propyl, hydroxyethyl, hydroxypropyl, cyclohexyl, or benzyl, according to whether alkylamines, hydroxyalkylamines, arylamines, cycloalkylamines, or aralkylamines are used. As starting materials may be used leuco-1.4- aminohydroxyanthraquinone itself or its substitution products free from further amino groups and from substituents in the 2- and 3- positions in the form of the crude reaction products mentioned above. Further substituents specified are hydroxy, alkoxy, sulpho and halogen, and starting materials specified are leuco-1-amino-4.5-dihydroxy-anthraquinone and leuco - 1 - amino - 4.5.8 - trihydroxy - anthraquinone. The reaction may be carried out at 70-120 C. in an open vessel or under reflux and in presence of a solvent such as ethyl, propyl or butyl alcohol. The oxidation of the leuco body may be effected by heating with nitrobenzene, by the action of free oxygen in presence of pyridine or piperidine, or by the action of dehydrogenating substances according to Specification 482,582. In an example, leuco quinizarin is reacted in alcohol with excess ammonia to give 1.4 - aminohydroxyanthraquinone which is then treated without isolation with a mixture of methylamine solution and monoethanolamine to give leuco 1-methylamino - 4 - hydroxyethylamino - anthraquinone, which is oxidized by adding copper sulphate and pyridine and blowing in air. Specifications 15355/08, [Class 2], 268,891, [Class 2 (iii)], and 441,043 also are referred to. The Provisional Specification covers the treatment of 1.4, - aminohydroxyanthraquinones whether isolated or not.

Title: Data Reduction System
IPC: H04N1/419
Filed: 1967-07-25
Abstract: 1,184,234. Digital transmission systems; facsimile systems. XEROX CORP. 25 July, 1967 [1 Aug., 1966], No. 34025/67. Headings H4F and H4F.  In an encoder for binary signals the number n (n= 1, 2, 3, &c.) of adjacent bits of one state, e.g. 0-bits, in the input is counted and the count represented by a corresponding binary word is transmitted, each bit of the binary word being accompanied by a tag bit, e.g. a 0-bit. A further signal representing the bits of the other state is transmitted. This latter may be a binary word derived in similar manner to that for the 0-bit groups or may be the 1-bits unchanged. Fig. 3 shows an example of the coding. The input data, line a is divided into groups of 1 and 0-bits and the number of bits in each group is counted, line c. To each count one is added, line d, and the count represented in binary form, line e. The most significant bit is removed, giving line g: these binary groups constitute the binary word referred to above. The bits in the words corresponding to 0-bit groups in the input data are accompanied by 0-bits, and those corresponding to 1-bit groups by 1-bits, giving line i which represents the data transmitted. Alternatively, Fig. 4 (not shown), the 1-bit groups are transmitted unchanged. The encoder, Fig. 5A, comprises shift registers 501, 505 and control unit 503, to all of which the binary input is fed. Register 505 stores adjacent 1-bits and register 505 stores 0-bits in the stages corresponding to those stages of register 505 containing 1-bits. Adjacent 0-bits in the input data are counted by register 501, no shift pulses being applied to either register during this process, and a binary word representing the count is stored in register 501. Those stages of register 505 which correspond to the states in register 501 containing the word are filled by 0-bits. The registers are connected to the gating arrangement shown which provides the coded output and also shift pulses which read the data in to a following buffer store. The arrangement is such that 1-bit groups are read out unchanged, whereas the binary words representing the 0-bit groups have a 0-bit preceding each bit of the word: in reading out the latter data the shift pulses to the buffer occur at twice the normal bit rate.
