Title: Composition suitable for use as desensitizing gumming solution for lithographic printing plates
Inventor: GARRETT WALTER L
IPC: C09K3/00
Filed: 1979-01-31
Granted: 1981-11-03
Abstract: An aqueous solution is provided which is suitable for use as a desensitizing gum for treating imaged lithographic printing plates, comprising (1) water, (2) an active polymer component for rendering non-image areas of a lithographic printing plate hydrophilic, comprised of a polyacrylamide-based polymer or copolymer or a blend of polyacrylamide and polyacrylic acid, or the like, said polymer or copolymer or blend having an average molecular weight of from 5,000 to 106 and having from 3 to 7 percent of the carbonyl sites as carboxyl groups, said active polymer component being present in an amount of from 3 to 30 weight percent of active polymer component, based on the weight of the active polymer component and the water, and (3) a suitable polyoxyalkylene glycol in an amount which is effective to reduce tackiness while the composition, said polyoxyalkylene glycol being selected from printing properties of a plate treated with said composition, said polyoxyalkylene glycol being selected from the group consisting of (a) a polyethylene glycol with an average molecular weight of at least 200, (b) a polypropylene glycol with an average molecular weight of at least 200; (c) a mixture of components from (a) and (b);(d) a triether of glycerine with a mixture of polypropylene and polyethylene oxides, and (e) a triether of glycerine with polypropylene oxides. The solution is particularly suited for treating imaged lithographic printing plates since, unlike earlier solution, it does not go through a tacky state when drying.

Abstract: A B S T R A C T    A rotary distributor fuel injection pumping apparatus has a rotary distributor member 28 rotatable within a sleeve 27 forming part of the body of the pumping apparatus.  The distributor member includes a transverse bore 29 which carries plungers 30 movable inwardly by cam surfaces on a cam ring 44, as the distributor member rotates.  The dis-tributor member is movable axially in the body to vary the amount the plungers can move outwardly and therefore the amount of fuel delivered by the apparatus.  The extent of outward movement is determined by complementary inclined surfaces formed on cam followers 44, 45 associated with the plungers and a part rotatable with the distributor member but axially fixed in the body.

Abstract: ABSTRACT            A method of packaging big web rolls of different sizes is based on the use of a roll packaging line with a plurality of separate roll handling stations and a roll moving arrangement for moving the rolls from one handling station to another. The method includs the steps of moving the web rolls in their axial direction at least through a majority of the handling stations, thereby keeping the rolls supported by moving members so as to avoid translational rolling of the rolls. Preferably the web rolls are moved in their axial direction also between the handling stations and hence, the web rolls will have a linear movement through the entire packaging line.

Abstract: ABSTRACT OF THE DISCLOSURE           This control device for an electric motor reducer is designed to permit the accurate adjustment of the point at which it is desired to stop the rotation of the unit.  For this purpose, it comprises a slide controlling during its movement in one direction and during a first time period the movement of beaks of a rocker in a direction in order to open the motor control switch when said beaks are engaged in notches of cam means.  In a second time period, the slide causes a two-armed sliding lever supporting the notched-cam shaft to pivot in a direction, each notched cam being rigidly associated with a heart-shaped cam and with a toothed wheel adapted, when inoperative, to mesh with toothed drive pinions.  In a third time period, the slide causes the beaks of the aligning lever to bear against the heart-shaped cams in order to align the notches with the beaks.  The pinions remain radially fixed. This device is particularly suited for controlling electric motor reducers for driving rolling shutters, roller-blinds and the like.

Abstract: La présente invention concerne un procédé de valorisation d'une coupe oléfinique renfermant essentiellement des hydrocarbures à 4 atomes de carbone par molécule et provenant d'une unité de craquage ou d'une unité de craquage à la vapeur. Ce procédé consiste à soumettre la coupe C4 oléfinique à une réaction de polymérisation isomérisante qui permet d'obtenir non seulement une transformation sélective de l'isobutène en dimères C8 et en trimères C12, mais également à provoquer le déplacement de la double liaison du butène-1 avec transformation de la majeure partie du butène-1 en butènes-2, pour atteindre, sous les conditions opératoires et avec les catalyseurs choisis, une composition assez proche de celle qui correspond à l'équilibre thermodynamique. Les autres constituants de la charge ne sont sensiblement pas transformés au cours de la réaction d'isomérisation. Cette transformation du butène-1 en butènes-2 présente un intérêt primordial pour la réaction d'alkylation effectuée après le fractionnement de l'effluent de polymérisation, car les produits obtenus par alkylation des butènes-2 possèdent un indice d'octane nettement supérieur à celui des alkylats issus du butène-1.
