Title: Apparatus for diverting sheet articles
IPC: B07C3/06
Filed: 1973-05-31
Abstract: 1428807 Directing sheets WINDMOLLER & HOLSCHER 31 May 1973 [15 June 1972] 26026/73 Heading B8R A deflector 6 for directing sheets W along alternative paths is biased to one or other of its operative positions by a chargeable energy store (e.g. double acting piston and cylinder 28) acting through a linkage 7. Movement of the deflector to follow this bias is prevented until a predetermined moment by a locking plate 27 which engages abutment 8<SP>1</SP> carried by a lever 8 connected to the linkage 7. The locking plate is moved to its inoperative position periodically in time with the intervals between sheets moving towards the deflector by a cam 22 and follower 25. For directing faulty sheets from the main stream a detector 39 senses the oncoming sheets and provides a pulse to comparator 40 in the event of a faulty sheet being detected. The comparator 40 also receives regular pulses from a microswitch 38 operated by a cam 37 in time with the intervals between sheets. Receipt of both pulses permits the valve 41 to operate and cause the piston 29 to be biased in a direction to move the deflector 6 to a position in which it directs the sheet out of the main stream. If no further pulse is then received from detector 39 the comparator 40 operates the valve to bias the piston in the opposite direction so returning the deflector to its initial position upon the next unlocking of the linkage 7. The detector may be replaced by a counter that is effective to direct a given number of sheets down each path.

Title: Process for the production of carbon black derivatives
IPC: C01B31/00
Filed: 1952-10-20
Abstract: Carbon black is modified by the addition of a desired radical such as -S, -CN, -OH or -OC6 H3 by reacting a halogenated carbon black with a compound containing the desired radical so as to bring about a transposition in which the halogen atoms of the carbon black are exchanged for the desired radical. Carbon blacks employed may contain 8-20 per cent. halogen and may be prepared by chlorination, for example, at 300 DEG C.  Generally an alkali or alkaline earth metal compound is provided to supply the desired radical.  Examples refer to the treatment of a carbon black containing 17 per cent. chlorine with sodium hydroxide, to introduce -OH groups, and sodium cyanide to introduce -CN groups, in both cases the transposition being effected by mixing carbon black and the reactant in a dry state and heating with agitation.  Solvents may, however, be employed or, if the reactant is a vapour, it may be passed over the black to be treated. Further reactants exemplified are alkali metal sulphides, sodium selenide sodium ethylate, phenolate, thiocyanate, potassium cyanate, ammonia, amines and amino silanes such as CH3 SiH2 NH2.

Title: Improved manufacture of phenolic condensation products
IPC: C08G8/28
Filed: 1925-10-23
Abstract: 255,692. Wade, H., (Karpen & Bros., S.). Oct. 23, 1925. Drawings to Specification. Phenol-aldehyde condensation products. - A fusible soluble condensation product is formed by digesting a phenolic body, such as phenol, a cresol or a naphthol, with a solution of hexamethylenetetramine and ammonium chloride at a temperature of about 100‹ C., the phenolic body being used in such excess that the resin formed contains about 1.5 phenolic groups to each methylene group, and the solution of hexamethylenetetramine and ammonium chloride utilized being that resulting from the interaction of methyl chloride and aqueous ammonia, the large excess of the latter used in the reaction being first distilled off. The ammonia liberated during the formation of the resin is recovered, and the aqueous ammonium chloride is decanted off from the resin and treated with hydrated lime to convert it to ammonia, the ammonia being caused to react with more methylene chloride to produce a further solution of hexamethylenetetramine and ammonium chloride for the continuation of the process. All ammonium chloride is removed from the resin by kneading or agitating it with water, and all water and a part of the free phenol then distilled off, either by boiling or by blowing air through the heated resin. The resin formed is unchanged by boiling, and, after purification, may be converted to an insoluble and infusible resin by heat after the addition of an active methylene body, such as formaldehyde or hexamethylenetetramine. Or the resin, after the addition of a methylene body, may be mixed with fillers or taken up in a suitable solvent to form a varnish. The proportions of hexamethylenetetramine and phenol used in the formation of the resin mav be varied, and equimolecular proportions may be employed, but the insoluble infusible resin then formed cannot readily be freed from water and ammonium chloride. A flow sheet of the apparatus is included in the Specification. Specifications 220,985, 235,015, and 246,416 are referred to.

Title: Method and apparatus for producing variable denier artificial melt-spun filaments
IPC: D01D5/20
Filed: 1961-07-25
Abstract: <PICT:0931380/IV(a)/1> <PICT:0931380/IV(a)/2> Variable denier artificial filaments of a synthetic polymer are produced by extruding the molten polymer downwards at a constant rate through a spinneret, cooling and solidifying the streams of melt thereby formed and taking up the filaments at a constant rate greater than the extrusion rate, a fine spray of a quenching liquid or jets of wet steam being directed against the extruded streams of molten polymer so that the droplets of liquid impinge on the streams when the latter have only travelled a short distance from the spinneret and are still in a molten formative state, as the result of which bulbous or thickened portions are formed along the polymer streams and the solidified filaments are slubbed.  As shown in Figs. 1 and 2, the molten polymer is extruded through the orifices 14 of a spinneret 12 to form streams 16 of molten polymer which are drawn downwards through a spinning chimney 18 by a driven bobbin 24.  The streams 16 are cooled and solidified by a horizontal current of cooling gas directed on to them through the pervious back wall 32 of the chamber 18.  The solidified filaments are drawn by the bobbin 24 through the yarn converging guide 20 and the traverse guide 22 to form a filament package 26.  A spray of droplets of water or jets of wet steam are discharged radially inward and generally upward towards the area in which the polymer first issues from the spinneret from a row of ports 44 in a tubular ring 36 disposed in a recess in the bottom of the spinneret head 10.  The spinneret orifices shown in Fig. 2 comprise an upper cylindrical portion 46 and a tapered lower portion 48, but may have other shapes.  The polymer may be nylon 6 or 66 or may be polyethylene terephthalate.  The spinning speeds may be above 200 feet per minute and the take-up speed, for example, 3,600 feet per minute.

Abstract: 817,266. Handling materials in radioactive environment. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 27, 1957 [Sept. 21, 1956], No. 26962/57. Class 39(4). An arrangement for transferring fuel elements from a pressurized fluid reactor 20 as disclosed in Specification 817,265 to a canal 30 beneath comprises a tube 26 in which a fuel element carrier 40 is moved piston-wise by fluid pressure supplied to the lower tube end through a conduit 132. An elongated fuel element 32 removed from the reactor core 22 by a handling device as discribed in Specification 817,265, after removal of the pressure vessel top 34, is inserted into the carrier 40 through aligned openings 38, 42 provided, respectively, in the top of the tube 26 and the carrier. A gate valve 84 normally obstructing the tube 26 is opened and the fluid pressure in the tube reduced so that the carrier descends to the Fig. 4 position, the fuel element then being removed through a tube opening 164 aligned with the carrier opening 42 by a long handled tool (not shown). The opening 164 is normally closed by a sleeve valve 167 and is opened by fluid pressure supplied at 186 to a piston rod 184 which raises the sleeve 167 through links 178, 180. For ease of maintenance the lower section 110 of the tube 26 together with the piston rod 184 and associated parts may be removed as a unit, and to this end the tube section 110 is releasably attached to the section 108 thereabove by withdrawing it telescope-like from a collar 112 secured to the section 108. The collar has a cut-away portion 114 so that after lowering of the section 110 the latter may be pivotted on a bracket 118 into the chain-like position shown. This telescope movement of the tube 110 is performed by fluid pressure supplied through a conduit 144 to a cylinder 128 in which the lower end of the tube acts as a piston, the cylinder resting within a cradle 154 hingedly mounted on the bracket 118 and may be removed therefrom in the chain-line position. The tube 26 is surrounded by a shroud tube, Figs. 2, 3 (not shown), where it extends through the concrete shield 24 whereby the portion of tube above the valve 84 may be withdrawn through the reactor top.
