Title: Improvements in or relating to the distributing mechanism of typographical composingand casting machines
IPC: B41B11/18
Filed: 1920-06-01
Abstract: 167,633. Linotype & Machinery, Ltd., and Billington, J. E. June 1, 1920. Distributingmatrices.-In machines having a number of magazines and a smaller number of distributors capable of co-operating with different groups of magazines, automatically variable fount-selecting means comprising ridged bridges engaging notches in the feet of the matrices are provided In the form shown in Fig. 1 in which two distributors 5, 6 co-operate with an adjustable column of four magazines 1, 2, 3, 4, a series of four fount-selecting bridges 8 is mounted stepwise on a slide 9 which is automatically moved. as the magazines ara shifted, so as to bring different bridges into the path of the matrices presented to the upper distributor 5. Matrices having notches which register with the bridge in operative position fail to engage the upper distributor and fall down a shoot 7 to the lower distributor 6 by which they are delivered to the upper magazine of the pair in use. The remaining matrices are delivered by the distributor 5 to the lower magazine of the pair. The slide 9 is operated by a lever 14 carrying a roller 16 which co-operates with blocks 18 secured in different positions on the magazines. During the shifting of the magazines, the lever 14 is moved clear of the blocks 18 by a connection with the usual magazines-locating means, which comprises rotatable turrets 19 carrying studs which engage gapped blocks on the magazine frame. The device may be employed in connection with a preliminary fount-separator by which the matrices are delivered to either of two distributors, the matrices which register with the bridge falling down a shoot 62, Fig. 7, to one distributor, and the other matrices engaging the ribbed bar 46 of the separator and being delivered by a shoot 64 to the other distributor. The bridges may, in this arrangement, be mounted on a pivoted sector or on a rotating drum or prism 50. The device may be applied to arrangements having three or more distributors bv the use of two or more bridge-carrying slides, which must be independently operable if it is desired to vary the order of the magazines in the column. By the use of an additional fount-selecting unit, matrices may be definitely selected for each of the magazines in use, rejected matrices being delivered to a pie-receptacle. In arrangements having stationary magazines and movable distributors, the fount-selecting bridges are adjusted by the distributor-moving mechanism. To avoid interference with the distributor screws, a modification may be used in which the fount-selecting bridges are carried on a slide movable parallel with the distributor, the required bridge being moved at right-angles to the slide into operative position by the magazinelocating means. Specification 12850/12 is referred to.

Abstract: Compounds which act as wax modifying agents or pour point depressors are prepared by condensing an aliphatic-substituted hydroxy aromatic compound having aliphatic groups containing only less than 6 carbon atoms with an acylating agent comprising an organic dibasic acid or halide anhydride thereof in the presence of a Friedel-Crafts catalyst separating the catalyst from the condensation product, and isolating from the product an oil-soluble fraction substantially non-volatile below 600 DEG  F. Phenols mentioned include the amyl phenols, isobutyl phenol, n-butyl phenol, isopropyl phenol, n-propyl phenol, cresols and the corresponding naphthol compounds.  Catalysts mentioned include aluminium chloride, boron fluoride, zinc chloride, ferric chloride, titanium tetrachloride, boron trichloride and hydrogen fluoride.  Acylating agents may be either aliphatic or aromatic, and are preferably used in the form of their acid halides or acid anhydrides.  Acids mentioned include phthalic, oxalic, malonic, succinic, glutaric, adipic, primelic, suberic and sebacic. The reaction is preferably carried out in an inert solvent such as a refined naphtha, kerosene, tetrachlorethane or carbon disulphide. The preferred proportions are from 1-5 mols. of the phenol to each mol. of the acylating agent.  The reaction is carried out between room temperature and 400 DEG  F., preferably between 100-300 DEG  F.  In an example, sebacic acid is treated with phosphorus trichloride to form the acid chloride, which is then reacted with tert.-amyl phenol in tetrachlorethane solution in the presence of aluminium chloride. After refluxing, the product is treated with water and the low boiling constituents removed.
