Title: Improvements in or relating to conveyor systems
Inventor: LEWIS THOMAS MALDWYN
IPC: B65G17/06
Filed: 1952-04-23
Abstract: 736,500. Endless-belt conveyers. CONVEYORS CAFETERIAS, Ltd. April 13, 1953 [April 23, 1952; Feb. 16, 1953], Nos. 10225/52 and 4236/53. Class 78 (1). In a conveyer in which a conveying run of slats is supported by rollers and a return run of slats underneath the conveying run is also supported by rollers, the rollers supporting the conveying run of slats are themselves supported directly or indirectly by the slats of the return run. In the embodiment shown in Figs. 1, 3, 4, the conveyer comprises slats 1 provided with box girders 2 which run on the rollers of stationary roller chains 3 which are anchored at each end to a girder 10, the slats being secured at each side to an endless chain 4 by a pin 5. Along the return run of the conveyer, the slats support the rollers of the chains 3 and are themselves supported on the upper run of three endless roller chains 7, the upper runs of these chains running on tracks 8, whilst their lower runs extend along channels 9. The chains 4 pass round sprockets 11, 12, 13 at each end. Beyond the end of the chains 3, rollers 6 on each slat drop on to rails 14 and then on to spring-loaded levers 15. These levers are then pivoted downwards and transfer the rollers 6 to rails 16 and the slats are then run on to the roller chains 7 extending around end sprockets 17. The sprockets 11 are driven by chains 18 from a driving shaft 19. The slats may be guided along their runs by rollers rotatably mounted about vertical axes on the slats and adapted to engage a fixed guide rail extending along the conveying run. Alternatively the guiding may be effected by flanged wheels mounted in the chains 4 engaging guide rails along the conveying and return drums. In a modification, Fig. 9, the slats are secured to the pulling chains by pins 24a, 24b which are displaced relatively to one another along the conveyer a distance equal to the radius of the sprocket wheels 25, 26. These latter are spaced longitudinally the same distance, whereby the slats are maintained horizontal while being carried around the sprockets 25, 26. In another embodiment (Figs. 10 to 14, not shown), the conveyer comprises a plurality of separate slats which are propelled along the return run by an endless chain located centrally beneath the return run and provided with laterally spaced rollers between which are bars which engage dogs projecting downwards from the lower face of the slats. The slats are transferred between the conveying and return runs by pivoted rocker arms which are provided at their ends with rollers for supporting the slats and are operated from a counter-balanced beam which is intermittently driven downwards and released, the downward movement being used to rotate the arms through 180 degrees.

Title: Process and Installation for Continuously Preparing Copolymers
IPC: C08F36/04
Filed: 1968-03-04
Abstract: 1,197,375. Polymerization process. STAMICARBON N.V. 4 March, 1968 [9 March, 1967], No. 10458/68. Heading C3P. In a process for continuously polymerizing two or more monomers in the liquid phase with a catalyst, and wherein the proportions of the monomers in the liquid feedstock are constant, the amount of reaction liquid introduced into the reactor is controlled to be inversely proportional to the pressure of a monomercontaining gas that is in equilibrium with the liquid feedstock, and the amount of catalyst introduced into the reactor is controlled in inverse proportion to the reaction temperature. The rate of flow of feedstock to the reactor is preferably controlled in a conduit between a vessel positioned before the reactor and the reactor, and the flow control is effected in dependence on the gas pressure in the vessel. The temperature of the feedstock between the vessel and the reactor may be lowered or raised in dependence on the level of the liquid in the vessel, the temperature lowering when the level rises and vice versa. The co-monomers may be ethylene and propylene. In the Figure, a suitable apparatus is illustrated wherein a stream of product, solvent and monomer leaves the reactor 1 and passes to the separator 6 from which the polymer is discharged through the conduit 7 and the remaining liquid is discharged through conduit 8. Constant flows of the monomers enter this conduit through conduits 10 and 12. From the condenser 14 the flow of liquid enters the vessel 15, which is equipped with a vent conduit 16, for venting undissolved gases, a pressure gauge 18 and level gauge 19. The outlet conduit incorporates a flow controller which is adjusted by the gauge 18. The conduit also incorporates a cooler 22, cooling conduit 23 incorporating a flow controller 24 which is adjusted by the temperature gauge 25. This adjustment is corrected by the level gauge 19. A constant flow of a third monomer may be added through the conduit 26.

Filed: 1963-03-16
Abstract: 1,018,435. Feeding webs. G. DURRANT & SONS Ltd. Feb. 28, 1964 [March 16, 1963], No. 10491/63. Heading B6B. [Also in Division F2] A flexible roller for controlling the direction of and weft tension in a fabric or paper web is formed of a centre section 11b and two outer sections 11a, 11 freely rotatable on slidably hinged shafts 9b, 9, 9a and enclosed by a continuous rubber sleeve 14, the shaft sections being adapted to move in a plane at right-angles to a plane containing pivots 7 at the ends of the outer shafts 9a, 9, which can be moved in opposite or like directions. For controlling the web tension (Fig. 1) the outer shafts 9a, 9 are carried in bell-cranks 8 pivoted at 7 and each connected through links 15 to nuts 16 on oppositely handed lead screws 17 driven by a reversible electric motor controlled by manual switches to raise or lower the centre shaft 9b, which remains parallel to the pivot plane. The movement is limited by switches engaging adjustable stops on one of the links 15. For controlling the lateral location of the web (Fig. 2) the bell-cranks 8 are directly connected by a link 22 and an extension 23 of one of the bell-cranks engages slidably a nut 25 on a leadscrew 26, chain-driven from a reversible electric motor 28 controlled manually or by feelers engaging the edge of the web so that on actuating the lead-screw the centre-roller section 11 is inclined to the pivot plane tending to move the web. A self-centring of the web is thus ensured. Two rollers are shown with their adjusting means interconnected for similar operation. A photo-electric scanner may be used instead of the web edge feelers influencing the electric motor or valves of a fluid operating gear. The web passes under a guide roll over the flexible roller 11 and under another guide roll.

Title: Improvements in the colouration of textiles of organic derivatives of cellulose
IPC: D06P3/40
Filed: 1948-04-15
Abstract: Textile materials of cellulose esters or ethers are coloured by mechanically impregnating them with an aqueous dye liquor which swells the cellulose derivative due to a content of swelling agent consisting substantially of lower aliphatic acid and an inorganic swelling agent.  The dye liquor may contain from 20 to 40 per cent of acetic acid and from 3 to 10 per cent of sodium, potassium or ammonium thiocyanate.  The dyestuff may be an acid wool or direct cotton dye or an insoluble dyestuff of the kind usually applied from aqueous dispersion.  The impregnated textile material may be immediately washed, the period of contact of the dye liquor with the material being of the order of 15 seconds or less.  In examples: (1) cellulose acetate fabric is padded at 25 DEG  C. with a dye liquor containing Artol Blue GL, 30 per cent of acetic acid and 5 per cent of sodium thiocyanate, rinsed and washed; (2) cellulose acetate fabric is padded with a dye liquor containing Amanil Chrysophenine G, 30 per cent of acetic acid and 5 per cent of sodium thiocyanate and then rinsed; and (3) a tow of cellulose acetate filaments is passed in six seconds through a dye liquor containing Vitrolan Yellow GR, Vitrolan Orange R and Artol Blue GL, 30 per cent of acetic acid and 5 per cent of sodium thiocyanate, and immediately rinsed.

Filed: 1927-04-19
Abstract: 269,596. Akt.-Ges. Brown, Boveri, et Cie. April 15, 1926, [Convention date]. Stuffing-boxes, substitutes for; connected to source of high or low pressure.-In a labyrinth packing for a turbine or compressor, an outer spsce 4 is maintained at a pressure slightly below atmospheric and an iner space 3 is maintained at a pressure slightly above that in the space 4, by automatic regulating means. If a, stage of the turbine &c. is at a pressure below atmospheric the space 3 is connected directly to that stage, but, if the lowest pressure of the turbine is above atmospheric, leakage into the space 3 is returned to the low-pressure stage by a compressor 12 and passages 5, 7, 11, and a further space 2 is connected directly to the passage 11 by a passage 6. The pressure in the space 3 is controlled by a regulator 8 connected by a, passage 9 to the passage 5 and by a passage 10 to atmosphere. In place of the compressor 12 an ejector may be employed operated by fluid from the turbine. The space 4 is connected by a passage 13 to a suction apparatus discharging to the atmosphere or to a recovery plant, the pressure in the space 4 being controlled by a regulator 14 connected by a passage 15 to the passage 13 and by a passage 16 to atmosphere. Instead of suction applied to the passage 13 a centrifugal blower may be mounted on the shaft in the space 4, the discharge from the space 3 being effected by an ejector. In this case a regulator controlling the supply passage of the ejector maintains a constant difference between the pressures in the spaces 3 and 4. If the pressure in the stage 1 is below atmospheric the connection 6 is dispensed with, the space 2 being supplied with fluid at a higher pressure than that in the stage 1.

Title: Improvements in or relating to electroplating onto steel or iron
IPC: C25D5/00
Filed: 1964-03-13
Abstract: In electroplating on iron or steel, etching is prevented in the non-plating low current density areas of the cathode by placing adjacent said areas an auxiliary electrode which is maintained more cathodic than these areas of the cathode.  The plating metal may be copper, chromium, nickel, tin, or zinc deposited from acid baths. The auxiliary electrode may be of carbon or any metal not appreciably affected by the plating bath e.g. Pb, Cr, Ag, Ru or the low hydrogen overvoltage metals set out below and may be of steel, especially if treated to resist corrosion and plating. Parts of the auxiliary electrode may be protected with masking tape and other parts by being placed in intimate electrical contact, e.g. by chemical or electrolytic plating, with a metal having a hydrogen overvoltage less than 0.33 volt measured at a current density of 0.1 amp/dm2 (see The Corrosion Handbook by H. Uhlig, John Wiley 1948) such as Pt, Pd, Rh, Ir, Au and Ni. As described the interior of a steel pipe is protected from etching when the outside is plated with chromium from a chromic acid bath including sulphuric acid and potassium silicofluoride by means of a more cathodic steel rod placed inside the pipe and masked with tape except adjacent the pipe ends where it is chemically coated with platinum from a chloroplatinic acid solution.
