Abstract: 1,039,569. Type-bar-making machines. ELTRA CORPORATION. Dec. 9, 1964, No. 50162/64. Heading B6W. In a type-bar-making machine, the finger 30, which lifts the matrices one-by-one clear of shoulders on supporting rails 26 for presentation to the distributing screws 13, 14, is moved upwardly in two stages, so that after the lifting of a thick matrix, the first stage of its next upward movement causes it to move in front of the following matrix. the arrival of which at the lifting position has been delayed by the thick matrix, and the complete movement becomes an idle one, whereby the following matrix is spaced from the thick matrix on the distributer bar by two screw turns instead of one. The likelihood of the thick matrix being struck by the following matrix when released by the distributer is thus lessened. The finger 30 is operated as usual from a cam 17 on the end of the screw 13, which is contoured to impart-the required movement of the finger in stages.

Abstract: 1444969 Combine harvester grain discharge tube control INTERNATIONAL HARVESTER CO 29 Oct 1973 [27 Oct 1972] 50168/73 Heading A1F [Also in Division F2] A control device is provided for moving the grain delivery tube of a combine harvester between its working and load transport positions and also for controlling the operation of the tube auger such that the latter can only be operated when the tube is in its working position, and the tube can only be moved when the auger is inoperative. The grain tube 2, Fig. 2, is moved by a hydraulic jack 12 which receives fluid from a distributor under the control of a hand lever 5, the position of which also controls the engagement or disengagement of a tension roller 32 with a drive transmission belt 24 which transmits drive to the auger 21 from shaft 22 via pulleys 25, 27, 29. Moving the lever 5 to the left from its Fig. 8 neutral position not only slides a lock 81 to the left but also pivots a pin 17, Fig. 5 connected to jack fluid distributor 16. Such that the distributor supplies fluid to cause the jack to move the grain tube to its operative position. The lever is then returned to its middle neutral position and then in the direction f 2  to disengage it from a second lever 56 which controls the pin 17 and distributor positions. The lever 5 is then moved to an end recess 78, Fig. 8, such that a shaft 53, Fig. 5, rotates to apply tension to a clutdh control cable (37), Figs. 3, 4 (not shown) via arm 54 and lost motion couplinig 55, 59. The tension roller 32, Fig. 2 is thereby engaged with the slack belt 24 to effect drive of the auger. The auger is stopped as soon as the lever 5 is returned to a recess 79 with the tube still in the working position. Movement of the lever to the right in Fig: 8 then causes the jack to move the tube to its road ransport position and restores the lock 81 to its original position.

Type 6 are on the ends of vertically sliding bars which have an integral horizontal extension 2 carrying sensing pins 47 corresponding to the type 6 carried by the bar. The pins sense perforations in the paper tape 5 and if they find agreement the type bar may make a complete upward travel and effect printing on the tape 5 through an ink-ribbon. If there are no holes, the pins 7 engage the paper tape 5 and the type-bars are held from an impression action. The tape 5 is moved step-by-step by pin wheels engaging a central row of feed perforations. After each step a shaft 15 having a print bail 1 is rocked clockwise and a spring 4 moves the sliding type-bar upwardly. Only partial movement occurs if there is to be no printing and the type is restored by the print bail 1 on its counter-clockwise movement. When printing is indicated by presence of correct perforations the type-bars move up further, and an interposer 3, pivoted on the bar, engages, by hooked end 21, over the print bail and is pressed by the bail 1 into contact with the ribbon and paper 5.

Filed: 1965-12-14
Abstract: A composition for preparing polyurethane/ polyureas comprises at least 10% by wt. of a diamino-polyurethane <FORM:1115788/C3/1> (G is a bivalent radical obtained by removing OH groups of a glycol; A is a bivalent radical obtained by removing amino groups from an aromatic diamine and R is H or a C1- 4 alkyl radical) together with an arylene diamine having pkb at least 8.7 which is present to provide at least 0.2 amine equivalents per amine equivalent of diamino-polyurethane plus arylene diamine.  The latter preferably has the formula <FORM:1115788/C3/2> where X is a direct bond or phenylene, -CH2-, -C(CH3)2-, O, S, S-S, or -SO2-; e.g. 4,41 - methylene - bis - (2 - chloroaniline).  The radical G may be derived from simple aliphatic diols, e.g. butanediol-1,3; butanediol-1,4; neopentyl glycol or diethylene glycol or alternatively it may be derived from a polymeric glycol, e.g. polyethylene ether, polypropylene ether or polytetramethylene ether glycol.  The radical A may be derived from the same or a different arylene diamine as used in the second component. Polyurethanes are prepared by reacting the above composition with an organic difunctional isocyanate terminated compound. The M.W. of the three components of the polyurethane are selected so that the number average molecular weight between urea groups in the polymeric chain is from 250 to 2500.  The isocyanate terminated compound may be either a simple diisocyanate, e.g. tolylene diisocyanate, methylene - bis - (4 - cyclohexyl - isocyanate) or methylene-bis-(4-phenyl isocyanate), or it may be a prepolymer formed by reacting a glycol with a diisocyanate.  Such a prepolymer is preferably prepared using at least 1.4 isocyanate groups for each OH group of the glycol. From 0.7 to 1.05 equivalents of diaminopolyurethane plus diamine may be present for each equivalent of isocyanate.  The diaminopolyurethane may be prepared by reacting the bischloroformate of the glycol from which G is derived with an appropriate diamine which may be the same as the diamine component of the mixture.  Mixing of the components may take place at 20-30 DEG  C.  The mixture may be used in the form of a two component pack the entire contents of which when mixed are used in the preparation of polyurethane/polyurea products having a number average molecular weight for units between urea groups in the polymer chain of from 250-2500, one part comprising the mixture of diamino polyurethane of the invention and the other a diisocyanate.
