Feeding sheets.-In the manufacture of paper tubes such as are used for the bodies of containers for jam or other foods, a sheet of paper is taken from a pile the support for which is automatically adjusted to maintain the topmost sheet at a predetermined level. The sheet may pass between printing rollers on its way to the mandrel. The sheets 5 are piled on a carriage 2 which is wheeled into place. Flexible cables 6<a>, secured at one end to the frame of the machine, pass under pulleys 4 on the carriage and are secured to chains passing over sprocket wheels 13. A weight 9<a> is hung on the end of the chain. The sprocket 13 is moved round step-by-step automatically by means of a ratchet wheel and pawl mechanism 14. The pawl 14 is oscillated during the running of the machine. Means, not shown, controlled by a roller resting on the topmost sheet. are provided to raise the pawl out of engagement and allow it to oscillate idly when the sheet is at the required height. The sheets are fed between rollers 35, 37 to travelling carriers by a rubbercovered roller 29 reciprocated by cam mechanism, and provided with a detent which allows the roller to roll over the sheet during the backward movement, but prevents rotation and so feeds the sheet to the rollers 35, 37 during the forward movement. On its way to the mandrel the sheet may receive any desired printed matter by passage between rollers 41, 42.

Filed: 1957-06-07
Abstract: In a process for the production of cross-linked plastics of high molecular weight by reacting linear or predominantly linear condensation and/or polymerisation products, which have terminal groups containing active hydrogen and molecular weights higher than 1000, with aromatic diisocyanates and glycols, hydroxyamines and/or diamines, the polycondensation and/or polymerization products, aromatic diisocyanates, glycols, diamines and/or hydroxyamines are reacted in such proportions that after the reaction has ceased, free hydroxyl or amino groups are still present in the polyaddition products and the storable products thus obtained are reacted at any desired time, either with mixtures of homologous polymeric urea diisocyanates of the general formula <FORM:0842339/IV(a)/1> or mixtures of these urea diisocyanates with homologous polymeru urethane diisocyanates of the general formula <FORM:0842339/IV(a)/2> in which formulae R represents an aromatic radical which is, if desired, substituted, x is an integer from 1 to 5 and Y represents either a straight-chained or branched aliphatic radical or aliphatic-aromatic radical, in which case the radical is linked to the oxygen atoms by way of aliphatic radicals and the diisocyanate mixtures are used in an amount in excess of that required to react with the hydroxy and/or amino groups of the polyaddition products, so that the storable polyaddition product is converted into the high molecular cross-linked condition.  The diisocyanate mixtures can be used in admixture also with a simple organic polyisocyanate or a masked isocyanate.  The radical Y, when an aliphatic radical, may contain hetero atoms, ester groups, urea groups and/or urethane groups.  The diisocyanate mixtures can be produced by the process of Specification 842,338.  A number of specific compounds, containing alkyl, alkoxy and halogen substituents in the aromatic nuclei is mentioned.  The compounds having terminal active hydrogen used in the first stage may be polyesters, polyethers, polythioethers or polyacetates.

Abstract: 877,160. Coiling wire on terminals; uncoiling. GENERAL ELECTRIC CO. Ltd. May 25, 1960 [May 29, 1959], No. 18389/59. Class 83 (4). A. device for wrapping and unwrapping wrapped electrical connections comprises a spindle having at one end a hole which extends lengthwise of the spindle to receive a terminal on which a connection is to be wrapped (or from which a connection is to be unwrapped), means arranged to supply or guide wire to said end of the spindle whereby when the spindle is rotated the wire is wrapped round the terminal to form a wrapped connection, a sleeve which encircles the spindle, and a projection on said end of the spindle such that when the end of a terminal on which a wrapped connection has been formed is inserted in said hole, said end of the spindle is pressed against the wire forming the connection, and the spindle is rotated in the opposite sense to that used in forming the connection, the end of the wire adjacent said end of the spindle is caught by said projection and forces thereby applied to the connection whereby the diameter of the turns of wire forming the connection is increased so that the wire contacts the inner surface of the sleeve and can then be removed from the terminal. To make a wrapped connection a piece of wire therefor is cut to length and inserted in a longitudinal groove 12 on a spindle 1 rigid with a handle 2 and is pushed along the groove 12 until its inner end is held by a spring clip 15 on the spindle. A sleeve 3 slidable on the spindle 1 is held in a retracted position thereon, compressing a spring 4, by a pin 8 engaging a part 10 of a slot 6 in the sleeve. A terminal to be wrapped is entered into a central hole 11 in the spindle 1 and, with the outer end of the wire held, the device is rotated so as to wrap the wire round the terminal until the inner end of the wire leaves the groove 12. To unwrap a connection the sleeve 3 is brought to its forward position, the terminal enters the hole 11 and the device is rotated so that a projection 20 on the helically faced end of the spindle 1 catches the end of the wire forming the wrapped connection so that it enters a groove 19 in the spindle extending at an angle to the groove 12 and the diameter of the wire turns forming the wrapped connection is increased until the wire contacts the inner surface of the extended sleeve 3 and can be removed from the terminal.

Abstract: 372,989. Resistances. LISSEN, Ltd. and WALKER, W., Worple Road, Isleworth, Middlesex. June 25, 1931, No. 18407. [Class 37.] A grid leak or like high resistance for small currents is made from a strip of prepared paper 2 wound helically on a core 1 of cord or string and has metal tags 3 at its ends embracing both strip and cord. The cord or string is impregnated with insulating composition, for instance by immersion for ten minutes in wax at 150‹ C., the wax comprising equal parts of heel ball and resin, with a little paraffin wax. A narrow strip of paper 2, such as that described in Specification 252,759, [Class 37, Electricity, Measuring &c.], is wound on the cord, and T-shaped metal tags 3 are attached by wrapping the broad limb round the cord. One tag is clinched tight and the second adjusted until the resistance has the desired value, and is then clinched. The cord is then cut off and the resistance unit immersed for an instant in paraffin wax at 85 to 95‹ C. The resistance is then inserted in a tube 4, Fig. 3, of varnished impregnated paper and the ends of the tags are bent round the ends of the tube, metal caps 5 being then pushed on. To prevent the tags from being dragged along the resistance by the caps 5, the tag stems may be slit as shown, one part being doubled inside the tube and the other part folded over the edge of the tube Alternatively the tag stem may be of greater width up to the ends of the tube than in the projecting part, so as to form a shoulder. A length of impregnated cord may be stretched between uprights, wrapped with paper and fitted with tags in pairs at the required intervals, the cord then being cut between adjacent tags, or the impregnated cord may be drawn forwards continuously and wrapped from a rotating roll of resistant paper.
