Title: Improvements in or relating to sheet stacking apparatus and stacking of sheets and tubes of paper or like material from a cutting off machine or other processing machine
Inventor: NIELD LESLIE CAMDEN
IPC: B65H29/06
Filed: 1957-02-15
Abstract: 852,112. Sheet-delivery apparatus. CHADWICK & SONS Ltd., J. March 5, 1958 [Feb. 15, 1957], No. 5174/57. Class 100(1) Apparatus for retarding and bringing to rest sheets being delivered by gripper-flyers 2 to a stack 7 comprises one or more slotted suction pipes 5 moving in a circular path above the rear edge of the stack and adapted to engage the rear edge of each sheet as it is being delivered, the suction pipes being rotated by epicyclic gearing so that the slots 6 always lie in the same direction relative to the plane of the stack. The axis 4 of the circular path followed by the pipes 5 is disposed at a lower level than the axis of a delivery drum 1 or arcuate part of a delivery conveyer, and when the axes of the drum 1 and of a pipe 5 and the axis 4 are in line, the slot in that tube lies in that line. The pipes 5 are mounted in a rotary end plate 11 and carry pinions 8 meshing with pinions 9 also mounted on the plate 11, the pinions 9 engaging a fixed pinion 10 mounted on the axis 4; the pinions are such that the slots 6 have no movement relative to the axes of the pipes 5. At the opposite end to the plate 11 the pipe ends move over a circular plate having an arcuate groove to which suction is applied, so that as a pipe end moves over the groove suction is applied to the pipe during the period it is engaging the tail end of a sheet. The speed of the pipes 5 along their circular path is less than the speed of the grippers 2 so as to cause the suction to retard the sheets. The stack is automatically lowered and may be divided into counted batches by opening the grippers earlier than normally so as to displace one sheet relatively to the stack after a predetermined number have been delivered.

Title: Improvements in or relating to catalytic reactors
IPC: B01J8/00
Filed: 1956-02-20
Abstract: <PICT:0795403/III/1> A catalytic reactor comprises a tower containing an assembly of imperforate tubes and transverse baffles on and between which the catalyst is maintained surrounding the tube assembly, in which the tubes run the full length of the reactor and are hermetically secured at the inlet end only, the baffles being provided with apertures through which the tubes pass freely, to permit expansion.  The upper part of the reactor comprises a heat exchanger in which the transverse baffles are mounted close together, and the lower part a reaction zone in which the baffles are more widely spaced.  In a suitable construction, a reactor cartridge is mounted within a high-pressure tube 1, and is divided into a heatexchanger zone 2 and reaction zone 4 containing the catalyst.  A large number of tubes 7 are secured (by welding or screwing) to an upper plate 8, and pass freely through openings in baffles 9, 91, gratings 13, 131 to the lower plate 10. The baffles are made of a softer metal (e.g. copper) than the tubes.  The baffles may be linked together and secured to one of the tubes.  At the base is a chamber 11 containing an electrical heater 12 or other means to start the reaction.  The reaction mixture enters through an opening 5 and passes up the outer jacket 6 where it is preheated and then passes downwards through the tubes 7 to the heating chamber 11, and then rises through the beds of catalyst in a zig-zag path, provided by the imperforate spaced baffles 9.  The gaseous products finally enter the heat-exchanger zone 2 where the baffles 91 are mounted close together, and may contain an inert granular material.  The gases flow to an exit either by an outlet 16, or by-pass 17 controlled by a gate valve 15.  By this means the rate of flow of gases through the reactor is controlled and thereby also the temperature in the reaction zone.

Title: Improvements relating to monoazo dyestuffs containing disulphimide groups and their use
IPC: C09B29/30
Filed: 1958-02-18
Abstract: The invention comprises dyes which are free from SO3H and COOH groups and are of formula:  <FORM:0840182/IV (c)/1> where A is a benzene or naphthalene residue, B is a benzene residue bound to the azo link #s to a sulphone or sulphonamide group, X is H or OH and Y is -SO2-alkyl, -SO2-aryl, -SO2-O-aryl and -SO2-R where R is a secondary amino group.  They are made by coupling, in an acid, preferably aqueous organic medium, a diazo composed of an amine of formula A-SO2,-NH-SO2-B-NH2 with an appropriate 2-naphthylamine.  The diazo compounds are preferably made by an indirect method.  Preferred dyes are made from diazo components which contain the diazo group in the #s-position to a disulphimide or sulphone group and in which Y is -SO2 N-(phenyl),Me or Et.  Other preferred dyes are those in which A is an unsubstituted or chloro or methyl substituted phenyl radical. The aryl residues, especially A and B, may contain groups such as alkyl, trifluoromethyl, tetramethylene, ether, alkyl- or phenyl-thio, sulphoxide, sulphone, sulphonamide groups derived from secondary amines, sulphonic acid aryl ester, carboxylic acid ester, cyano and halogen groups.  Indicated for A are residues of benzene, toluene, xylene and cymol sulphonic acids, mono- or di-halogenbenzene- and halogen alkylbenzene sulphonic acids and naphthalene-, dybenyl- and tetrahydronaphthalene sulphonic acids. Indicated for B are residues from 2-aminobenzene-1-sulphonic acids e.g. 4- and 5-halogen-, acylamino and alkyl-and aryl sulphonyl and 4-alkyl and alkoxy2-aminobenzene-1-sulphonic acids and 3-amino-4-aryl-or-alkyl-sulphonyl-, sulphonic acid aryl ester- or sulphonic acid amide-benzene-1-sulphonic acids. Specified secondary amines from which Y may be derived are dimethyl, dibutyl, diethyl, N-methyl-phenyl, N-ethyl-phenyl, N-butyl-phenyl and dicyclohexyl-amines.  Sulphonic acid phenyl- and methyl- and chlorophenyl ester residues are also indicated for group Y.  If X is OH, Y is preferably in the 6-position.  Indicated as azo components are derivatives of 2-naphthylamine -5-, -6- or -7- and 2-amino-8-naphthol-6-sulphonic acids.  The dyes colour wool, silk, Lanital, polypeptide and polymethane fibres in orange to red shades. They may also be used in printing processes and especially in the "Vigoureux" process. Numerous examples are provided illustrating the preparation of the dyes and their use in dyeing processes, the components being chosen from those indicated above and additional components including those in which A is substituted by acylamino groups.

Filed: 1969-02-03
Abstract: 1300231 Photo-electric line following apparatus BRITISH OXYGEN CO Ltd 30 Jan 1970 [3 Feb 1969 5689/69 Heading G1A A line or edge follower has a contrast mask attached to the follower and scanned by the photoelectric device to provide a 'virtual' line for the follower. As shown, the mask has a white area 12 and a bordering black band 24 with an edge 20. In operation the photo-electric device scans transversely to the edge being followed over a distance 26 which when following correctly produces the situation shown in (a). If the follower deviates as shown in (b) a major proportion of black is sensed and the contrast between areas 24 and 12 provide an error signal. If an opposite deviation occurs (c) the follower only senses a line as wide as band 24 which produces an appropriate error signal to drive it back to position (a). Masks in white only or in a light shade of grey could be used but have disadvantages that the direction of the error is inditerminate under certain conditions or contrast may be lost when the mask gets dirty.

Patent GB-567107-A (GB)
Title: Improvements in shrinking textile materials having a basis of an organic derivative of cellulose
IPC: D06M13/08
Filed: 1943-04-15
Abstract: Textile materials having a basis of an organic derivative of cellulose, e.g. a cellulose ester, ether, mixed ester, or mixed ether-ester, are subjected to a shrinkage treatment, whereby their extensibility is improved, by applying a mixture of methylene chloride and ethylene dichloride, in which the proportion of methylene chloride exceeds 50 per cent.  The mixture is applied to the materials at a temperature of 15-25 DEG  C.  Filaments, threads, yarns, or fabrics of a wet-spun or dry-spun and stretched cellulose derivative are treated, if desired, under tension, with the mixture byepassing them through a bath or spray, or over wicks or pads. Alternatively, the material may be treated in hank form. The materials are subsequently freed from the mixture by washing with, for example, an organic solvent.  The cellulose derivative yarn may be associated by weaving, knitting or twisting with yarns of natural silk, wool, cotton, regenerated cellulose, or one or more different types of cellulose derivative, and subjected to the shrinkage treatment whereby fancy effects, e.g. slub, pebble, cockle or crepe effects are produced.  Brocade effects are produced on fabrics by local application of the mixture, e.g. by printing.  The process also reduces the tendency of knitted fabrics to ladder, of warp-knitted fabric to split, and of woven fabrics to slip, and may be applied to umbrella fabrics so as to tighten them on their frames.  In the examples: (1) dry-spun cellulose acetate yarn is stretched and immersed in hank form in a mixture of 64 per cent methylene chloride and 36 per cent ethylene dichloride at a temperature of 19 DEG  C. for 20 seconds, removed, washed with carbon tetrachloride and dried; (2) as in example (1), but the material is passed continuously through the bath. Specifications 371,461, 380,504, 389,823 and 407,357 are referred to.
