Title: Improvements in the distributing mechanism of typographical composing machines
IPC: B41B11/18
Filed: 1921-07-30
Abstract: 186,214. Hart, H., (Mergenthaler Linotype Co.). July 30, 1921. ing matrices. - Two or more distinct distributor bars, for example one for ordinary founts of 90 characters and another for special founts of 72 characters, are arranged for selective co-operation with a single set of conveyer screws s and a single distributor box, preferably by movement of the bars, corresponding shift of the magazines and magazine entrances being effected in known manner. As shown in Fig. 2, two distributor bars C, V are arranged back to back and mounted for inversion, to bring either bar into operative position between the conveyer screws F. Inversion is effected by a rotary movement, the combined bar having at each end two journal pins C<1>, V<1> supported in brackets G formed on their inner faces with continuous grooves presenting a semicircular portion G<1>, a straight portion G<2>, and a bearing-surface G<3>, The pins are out away at the ends to semicircular cross-section with the flat portions in opposite directions as shown in Fig. 6, to permit movement past the bearing-surface G<3>, inversion being effected by a clockwise rotation of the bar. The rear conveyer screw F is mounted on pivoted arms F<3> so that it can be swung upwards, as shown in dotted lines, to permit the movement of the combined 'bar, and the arms F<3> are provided with fingers F<5> which contact against the flat portions of the lower journal pins to maintain the bar in vertical position. In another arrangement, shown in Fig. 7, two distributor bars C, V are disposed side by side and connected by a spacing member J formed with a handle J', and to parallel-motion links J<3>, J<4>, for movement in an orbital path into two positions determined by stops J<7>. In another arrangement, shown in Fig. 9, the bars C, V are mounted to slide and turn at one end independently on a transverse rod K, the inoperative bar being moved backwards or forwards from the middle position and retained in vertical position by a corresponding pin K<2> or K<3>. The free ends of the bars are provided with pins K<4> to engage in a recess in the framework in the operative position. Means may be provided for effecting the movement of the 'bars from the front of the machine. For example, in the arrangement shown is Fig. 7, the member connecting the two bars may be connected by linkage to a hand-lever located at the front of the machine.

Title: Manufacture of oil-soluble synthetic resins
IPC: C09F1/00
Filed: 1932-07-20
Abstract: Oil-soluble synthetic resins are made (1) by causing an aromatic compound containing a readily exchangeable halogen to react with a recent natural resin and esterifying with a mono- or polyhydric alcohol, or (2) by causing an aromatic compound containing a readily exchangeable halogen atom to react with a product obtained by esterifying a recent natural resin with a mono- or polyhydric alcohol.  In examples (1) American colophony and benzyl chloride are condensed in presence of zinc chloride as catalyst and the product esterified with glycerol in xylene; (2) Swedish resin is fused with benzalbromide a solvent, e.g. chlorbenzene being added towards the end of the reaction and the product esterified with glycol; (3) manila copal is condensed with xylyl chloride (from commercial xylene and chlorine) and the resin treated with benzyl alcohol; (4) American colophony is condensed with the product obtained by treating xylene with hydrochloric acid and formaldehyde so that a mixture of mono- and di-chlorinated products is formed and towards the end of the reaction tetrahydronaphthalene is added whereupon the resin is heated with glycerine; (5) the product from German pine resin and p-tolylchloride-carboxylic acid (from p-tolylbenzoic acid and chlorine) is esterified with glycerine; (6) retene is chlorinated and the product fused with a colophony-glycerine ester in presence of rosin oil; (7) colophony is chlorinated in chlorbenzene until the product corresponds to about one atom of chlorine to four molecules of abietic acid and the product heated so that the chlorinated rosin acid reacts with the non-chlorinated acid, whereupon the resin obtained is esterified with glycerine; (8) an ester resin from French colophony and glycerine is condensed with di-w-chlormethylxylene (from m-xylene, hydrochloric acid and formaldehyde); (9) chlorinated anisole containing two Cl-CH2- groups (from anisole, hydrochloric acid and formaldehyde) is fused with colophony and the product esterified with glycol; (10) French colophony is heated with a salicyclic acid containing two Cl-CH2-groups (from salicyclic acid, hydrochloric acid and formaldehyde) in xylene and esterified with glycerine; (11) Hercules resin is fused with 1-w-chloromethylnaphthalene and the product esterified with glycol; (12) American colophony is fused with di-(4-chloromethyl)-diphenyl (from diphenyl, formaldehyde and hydrochloric acid) and the product esterified with pentaerythrite in xylene.  Other reagents are also specified.  Specification 361,951 is disclaimed.  The Specification as open to inspection under Sect. 91 comprises also an example in which a derivative of xylene containing one chlorine atom in each side chain and several chlorine atoms in the nuclear is fused with Hercules resin and the product esterified with glycerine in xylene. This subject-matter does not appear in the Specification as accepted.

Title: Flexible blade fan
IPC: F04D29/38
Filed: 1966-05-10
Abstract: 1,105,865. Axial-flow fans. WALLACEMURRAY CORPORATION. May 10, 1966 [May 10, 1965], No.20605/66. Heading F1C. In a fan, particularly for cooling I. C. engines, the blades 14, Fig. 2, are flexible so that their pitch automatically reduces as the speed of the fan increases. Each blade is riveted at 21 together with a clamp member 17 and a backing plate 18, to an arm 12 extending radially from the hub 11. The backing plate reduces the stress concentration in the blades at the rivets. Moreover, the relative movement between blade and backing plate damps blade vibrations. The free radial edge of the backing plate may be bent away from the blade to limit the deflection of the blade and provide further support at maximum deflection, Fig. 3 (not shown). The arms 12 are asymmetrically spaced around the hub 11, Fig. 1 (not shown).

A multi-layer cable joint is made by stripping the insulation 1, 2 to expose the outer layer 9 of the stranded conductors which are cut back and bevelled at 3, 4 and then spread out on one side 2 of the joint. There is then wholly slid thereon a sleeve 5 which is internally chamfered at 6 and has a slot 7 at one end, the slot being wider than a strand so that the latter can be easily inserted through the slot. The cable ends to be joined are abutted and the sleeve 5 slid over the join till one end fits the bevel 3 on the cable end 1. A strand 9 is pushed through the slot 7 which may be skewed and the sleeve is turned so that the strands can be pushed in turn into position through the slot. When all the strands 9 are in position, the sleeve is given a fraction of a turn to retain them and solder is poured into it through an aperture 8 therein. The joint is finally sealed and the cableinsulation restored.
