Title: Method of controlling shrinkage of a sleeve wrap on a container
IPC: B29C63/42
Filed: 1977-03-30
Abstract: 1522934 Heat shrinking sleeves onto containers OWENS-ILLINOIS Inc 30 March 1977 [31 March 1976 (2)] 13336/77 Heading B5A In a process for heat shrinking a sleeve 16 onto a container 11, such as a bottle, the container and sleeve are rotated during the shrinking operation at a speed sufficient to centrifugally rigidify the sleeve (see sections 16d and 16c of the sleeve) during the period immediately preceding shrinking, during which period the sleeves becomes heat softened and limp. In this way the formation of folds in the sleeve is prevented. In a preferred embodiment, sleeves are fed over containers carried by rotatable chuck suspended from a closed looped conveyer. The containers and sleeves are passed through a heat shrinking area in which first the central part of the sleeve is heat struck and then the end parts. During passage through the oven a disc carried by each chuck engages a driven belt to rotate the chuck at centrifugal speed. In an alternative embodiment each chuck carries a sprocket engaging a link chain to effect the rotation.
Patent GB-592767-A (GB)
Title: Improvements relating to the treatment of aqueous liquors containing thiocyanate
IPC: B01J41/04
Filed: 1945-05-28
Abstract: A process for the removal of thiocyanate, with or without thiosulphate, from an aqueous industrial effluent or other liquor consists in passing the liquor through a bed of an anion-exchange material containing replaceable mineral acid anions to bring about exchange of these for the thiocyanate and any thiosulphate ions.  The exchange material may be treated with a mineral acid preferably sulphuric acid, so as to be substantially saturated with mineral acid ions, or it may be saturated by means of the liquor itself, by the liquor being passed first through a bed of hydrogen-exchange material containing exchangeable hydrogen ions, before passing through the bed of anion-exchange material.  As an example, liquor containing .5 per cent ammonium chloride, .05 per cent ammonium thiocyanate and .04 per cent ammonium thiosulphate was passed through a granular bed of anion-exchange material prepared as described in Specification 577,351 and saturated with sulphate ions.  When the effluent showed an increase of ammonium thiocyanate, the bed was regenerated with .7 per cent ammonia and rinsed with .1 per cent sulphuric acid, which extracted the thiocyanate and thiosulphate ions in a much more concentrated form than in that of the original aqueous liquor.

Title: Process for the manufacture of panels in particular for buildings
IPC: E04C2/24
Filed: 1968-03-20
Abstract: 1,224,028. Laminate. COMPAGNIE DE SAINT-GOBAIN. 20 March, 1968 [22 March, 1967], No. 13459/68. Heading B5N. [Also in Division B2]  A first thermosetting resin in paste form is foamed in contact with a layer of a second thermosetting resin so that the foaming exerts pressure on the layers, and the resins are set simultaneously, bonding under the influence of the pressure. The paste may be located between two layers of the second resin to form a sandwich laminate. The layer or layers of the second resin may be reinforced with fibres of glass or asbestos or fibrous mats. The first resin may be polyurethane, polyester or epoxide resin. The second resin may be polyester or epoxide resin. As shown, a layer of glass fibres 3 impregnated with polyester resin 4 is formed on a web of regenerated cellulose 2, which is unrolled on to an endless belt 1. The layer has its thickness determined by a doctor blade 5 and is partially set by an infra-red heater 6. A similar layer is formed on a regenerated cellulose web 8 covering a second endless belt 9. Polyurethane 7 is foamed between the two layers as the latter are fed between the belt 1 and a third endless belt 15. Pressure arising from the foaming between the belts promotes adherence of the foam to the reinforced polyester layers. Heat evolved by the foaming polyurethane is sufficient to heat-set the layers of the panel. Alternatively, heat may be supplied to or withdrawn from the panel during its formation. The panel edges may be delimited by side pieces (not shown). In a modification, Fig. 2 (not shown), devices (27) and (28) are provided for bending the two reinforced polyester covering layers, so that each of the latter is formed with two lateral flanges extending perpendicularly to the body of the respective layer. Opposed flanges of the two covering layers are sealed together optionally with the introduction of supplementary resin-impregnated strands so that the polyurethane foam core is covered on both sides and both edges. In this embodiment, the polyurethane is supplied from two reservoirs (26) and introduced between the two covering layers by nozzles (25). The covering layers are pre-formed glass fibre mats which are impregnated with the polyester resin on the respective regenerated cellulose webs. Abrasive brushes (32) are provided to tear the outer cellophane cover away from the completed panel. A cutter (33) is provided for cutting the laminate into panels of the desired length.

Abstract: A process for the production of a dialkyl phenol comprises reacting phenol with an alkylating agent at a temperature not less than 140 DEG  C. to introduce two alkyl groups into the nucleus in the presence of a catalyst comprising an activated bleaching earth and a strong acid. In modifications of the process a monoalkyl phenol is employed as starting material and 3,5-dialkyl phenols are produced by reacting (1) phenol or (2) a 3-alkyl phenol or (3) a 4-tertiary-alkyl phenol or (4) a 3-alkyl-4-tertiary-alkyl phenol or (5) a 2-tertiary-alkyl phenol with an alkylating agent under the conditions specified above. The term "activated bleaching earth" denotes a clay or earth such as montmorillonite which has been treated with mineral acid. The strong acid referred to above may be any acid effective to catalyse the alkylation of phenols, e.g. sulphuric acid or 90% phosphoric acid.  Any alkylating agent effective to introduce cycloalkyl or open chain alkyl groups into the nucleus may be employed, olefins, olefin dimers and alkanols being preferred. Examples are furnished.

Abstract: 528,539. Cutting rubber tubes. FIRESTONE TYRE & RUBBER CO., Ltd. May 9, 1939, No 13829. Convention date. Mav 13. 1938. [Class 31 (i)] [Also in Group V] Unvulcanized inner tubes for pneumatic tyres are spliced by flattening the ends, trimming them by transverse slicing cuts made by heated knives moving in arcuate courses in vertical planes, and finally pressing the tacky trimmed ends together to afford a butt joint. The operations are performed by the machine shown in side and front elevation in Figs. 1, 2. The ends of the tubing to be spliced are placed over the lower dies of grippers 36, 37, with the ends to be trimmed protruding inwardly, the lower die 36 of the right hand set, Fig. 2, being mounted on a slide 28 and capable of movement towards or away from the other lower die. The upper dies 37 are vertically reciprocable by racks and pinions actuated from the pistons of air pressure cylinders 50 controlled by manually operated valves 52, 53. The tube ends being held in the grippers are trimmed by parallel knives 17 carried by a manually operated counterweighted arm 13 pivoted to the frame of the machine at 12 and shown in the raised inoperative position in the Figures, the cutting taking place against a plate 59 raised into position by the admission of pressure fluid into the lower end of cylinder 63, the ends being held down by a presser plate 18 disposed between the knives. After the trimming, manual operation of valve 69 lowers plate 59, and arm 13 is raised by the handle 16, the downward movement of counterweight 14 causing a cam 57 to operate a valve admitting fluid to charge cylinder 31, Fig. 3, and through piston rod 33 and links 34 to move slide 28 to the left, bringing the two sets of grippers into contact and effecting the splicing of the trimmed ends. The movement of the slide closes a switch 88 which sets in operation a timing device 83 and as a result valve 75 is actuated and an air blast from nozzle 71 clears the trimmings from the plate 59. After an interval, during which the tube ends are uniting under pressure, the timing device operates to charge the upper ends of cylinders 50, raising the upper dies 37, a cam 55 on one die head 43 actuating a valve 54 to admit fluid to cylinder 31 to retract the slide, whereupon switch 88 is opened and the timing device ceases to operate. The splice is formed with an external ridge which disappears during vulcanization in a mould under internal pressure.
