Abstract: In a cartridge (14) for an endless typewriter ribbon (10), a fresh ribbon is stored in the cartridge (14) with a substantial length of ribbon (10) wound in a convolute around a roller (26). When the cartridge (14) Is mounted in a printing apparatus, the ribbon (10) Is drawn from the cartridge (14), exhausting the convolute. When the cartridge (14) is fully mounted in position in the printer, a single path of ribbon (10) extends into the cartridge (14) and through an opening (24) along a chord of the roller (26) and out from the cartridge (14). A brake (28) is provided to limit motion of the roller (26) so as to preclude premature unwinding of the convolute and to limit oscillation of the roller (26) during operation of the printer. With the normal operating path of the ribbon (10) extending through the chord-oriented slot (24) of the roller (26), ribbon (10) can readily be rewound onto the roller (26) upon removal of the cartridge (14) from the printer.

Abstract: A method is described for obtaining a tenacious in si- tu coating deposition of calcite on the inner surface of water pipes. The calcite coating method according to the present invention has an advantage that it is able to maintain a completely corrosion-free system during the coating, thus assisting the formation of a protective coating of good bonding bonding properties. 
     The method consists in the incorporation of a reagent selected from the group consisting of alkali metal sulfite and hydrazine, in an amount which is at least the stochio- metrically required to deoxygenate the aqueous solution utilized for said coating, which is supersaturated with respect to calcium carbonate having a dissolved calcium and carbonate levels of above 100 ppm. The calcite producing ingredients are supplied to the water stream in quantities supplementing concentrations available in thenaturalwater used, giving the required supersaturation levels by addition of suitable satts. 
     The calcite coating can be successfully applied to large diameter mains and pipes by utilizing a large recycle ratio. The coating has in particular an improved adherence on the wall of the pipes, when the water is delivered at a flow velocity of above 1.5 m/sec.

Abstract: A fuel injection apparatus for internal combustion engines, in which the onset and end of injection are determined by a hydraulically actuated control slide. The injection pump of the apparatus, which is preferably combined with an injection nozzle to form a pump/nozzle unit, has a pump piston embodied as a differential piston, whose section having the larger diameter serves as an auxiliary pump piston and generates a control pressure (pS) actuating the control slide. During its compression stroke the control slide, in order to initiate the onset of injection, closes an overflow line leading out of the pump work chamber; and during its return stroke, which is effected by the pressure drop in the control line, the control slide relieves the overflow line in order to control the end of injection. The control pressure (pS) in the control line necessary for actuating the stroke movement of the control slide is controlled by the closure of this line by means of a control device and is built up during the compression stroke of the auxiliary pump piston.

Abstract: A process for reacting a mixture of branched and linear alcohols with a caustic, optionally in the presence of a catalyst, to produce a reaction mixture containing carboxylic acid salts, and to liberate hydrogen comprises introducing into the reaction mixture at about a time when a significant evolution of hydrogen from the mixture begins to occur, an effective amount of an inert diluent for the reaction mixture. The effective amount is sufficient to maintain the fluidity of the reaction mixture. A preferred diluent is mineral oil. By operating in this way the tendency of the reaction mixture to foam and solidify is reduced, thus permitting the reaction to proceed to completion and permitting the easy removal of the reaction mixture from the reaction zone. The production of a branched and linear mixture of carboxylic acid salts which substantially corresponds to the branched and linear mixture of alcohols reacted is also ensured.
