Abstract: A piston machine has a piston movable in a cylinder. The piston has a peripheral surface defining a clearance space with the inside cylinder surface. An annular slot in one of the surfaces is surrounded by, and communicates with, an annular chamber forming part of the one surface and an annular hollow conductor in the chamber has an apertured wall portion facing the slot. An anode and at least one cathode contained in the conductor are operable to cause electrons to be emitted from the cathode and to become trapped by gas molecules contained in the conductor so that the gas molecules are converted into gas ions, to cause the gas ions to move through the apertured wall portion and the slot into the clearance space, and to cause electric fields to confine the gas ions in the clearance space to form a gas ion barrier which seals the clearance space.

Abstract: In a baling operation that uses a continuously reciprocating plunger, if the next charge to be stuffed into the chamber has not yet reached the desired size and density by the time the stuffing fork is ready to begin its next operating cycle, the fork is temporarily deactivated, without affecting the plunger, until the charge reaches full size and density. Thereupon, the fork stuffs the entire charge into the baling chamber in a single cycle of operation for compaction by the plunger. The baler is loaded from the bottom of the baling chamber through an upwardly curved duct that serves both as an accumulating chamber and as a precompression area into which the charge is progressively packed by a rotating, retractable finger drum at the lower end of the duct. A backstop for precompression purposes may be presented at the top of the duct in a number of alternative ways, i.e.

Abstract: An improved mechanism for cleaning a driven blanket cylinder in an offset lithographic printing press is described. In the mechanism, a wash cloth is fed from a magazine roller over a pressure roller to a take-up roller. The pressure roller can be brought to bear against the dirty surface of the blanket cylinder with the wash cloth therebetween. The wash cloth is wetted by spraying a cleaning fluid thereon immediately prior to its encountering the pressure roller. The wet wash cloth is thus brought into contact with the dirty surface of the blanket cylinder which is then rotated against the cloth to cleanse the surface. After the surface is clean, dry cloth can be brought into contact with the blanket cylinder by merely not activating the fluid spray. Means are provided in the preferred embodiments for agitating the cleaning fluid to keep it well-mixed and means are also provided for collecting and reusing any excess cleaning fluid which may be dispensed.

Abstract: A projectile fired from a gun barrel, aimed in straight flight upon a small arget, has a massive armor-piercing body spacedly surrounded by a sleeve which defines with its outer surface a ring channel that may also serve as a combustion chamber for generating additional thrust. The sleeve, whose cylindrical outer periphery provides guidance in the gun barrel, is axially divided into a rear portion rigid with the massive body and a relatively slidable front portion. In an initial forward position of this front portion, an annular shutter mounted on its inner surface obstructs the ring channel by engaging an annular shoulder on the body, the sleeve then effectively acting as a sabot which blocks the escape of combustion gases from the gun blast.
