Abstract: PROCESS AND PLANT FOR MANUFACTURING      TELECOMMUNICATION CABLES            AbSTRACT OF THE DISCLOSURE     A process and apparatus for filling multi-conductor cables, particularly a telecommunication cable with several insulated wires surrounded by a covering and a sheath, with a mixture of powders which expand with the absorption of mois-ture.  The conductors are fed in spaced relation into the entrance of a casing having an interior, frusto-conical wall which decreases in diameter from its entrance to its exit.          The exit is small in diameter compared to the entrance so that the conductors converge as they pass from the-entrance to the exit.  Intermediate the entrance and the exit, the conductors are subjected to the powders which are caused to follow a helicoidal course by a screw which directs them toward the exit.  Due to the shape of the casing wall, the powders are forced toward the conductors.

Abstract: A B S T R A C T            METHOD OF SOLUTION MINING SALTS FROM               AN UNDERGROUND SALT DEPOSIT     Salts from a salt deposit including magnesium and potassium salts are mined by a solution process in a cavity at the lower end of a borehole. A solvent liquid (water) is injected into the cavity at a level that is periodically raised whereby super imposed slices or cuts of the part of the deposit around the borehole are consecutively dissolved. Brine is recovered from a low level in the cavity. The injection rate of the solvent liquid and the recovery rate of the brine are controlled such that the vertical distribution of the potassium content of the brine in the cavity shows a maximum within the uppermost slice or cut.

Abstract: -Abstract of the Disclosure Hand-held and hand-operated cutting tool particularly well suited for cleanly and quickly cutting plastic pipe or tubing, rubber hose, or the like.  The tool has a blade rotatable in increments or steps from a retracted position in which it is enclosed within a housing to a cutoff position in which it cooperates with a stationary anvil so as to sever the article to be cut.  A ratchet drive interconnects a movable handle and the blade so as to incrementally drive the blade toward its cutoff position upon manipulation of the handle.  A pawl prevents opening of the blade caused by the springiness of the article being cut upon being engaged by the blade.  Upon severing of the article, the blade may be readily returned to its retracted position by, for example, releasing a thumb operated locking pawl.

Abstract: ABSTRACT       In order to control the thickness of a metal or metal compound coating which is formed on a face of a freshly formed ribbon of hot glass during its travel from a flat glass forming installation by contacting such face at a coating station with a fluid medium or fluid media comprising a substance or substances from which the coating is formed, preparatory to being coated, the glass is thermally conditioned at a thermal conditioning station between the flat glass forming installation and the coating station, so as to eliminate or reduce temperature gradients across the ribbon width to be coated.  An apparatus suitable for carrying out this process comprises means for delivering at least one fluid coating medium into contact with the glass at the coating station, and means permitting the temperature of one or more portions of the ribbon width to be conditioned selectively or differentially at a thermal conditioning station located between the flat glass forming installation and the coating station.

Abstract: ABSTRACT OF THE DISCLOSURE           A character overprinting apparatus and method for overprinting in a laser non-impact printer is disclosed.          Control bits are generated and assigned to data words transmitted from a host system.  An underline control bit identifies whether the associated data word will require underlining and a data control bit identifies the data word as a character space or a character shape.  An intermediate storage register stores a line of data words and associated control bits for overprinting.    Stored data words and associated control bits from the inter-mediate storage register and data words and associated control bits from the host system are compared in an overprinting circuitry means to effect a selected merger of the data words and a selected modification of the control bits.  The merger and modification are done in accordance with a pre-selected set of overprint rules.  The merged data words and modified control bits are transmitted to the intermediate storage register, where they await further overprinting in the overprinting circuitry means or from where the data words are transmitted to a character generator memory in the laser printer to select character shapes stored therein for printing by the printing means of the laser printer.  At the same time, the modified underline control bit stored in the intermediate storage register and associated with stored data words are transmitted to the printing means, whereby selected character shapes are underlined when printed.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to the arrangement of a switching network for use within an electrical power distribution system.  There is an improved security of power delivery to various loads while at the same time enabling a reduction in the number of required circuit breakers and related gear.  This network also presents additional options in design and operating modes, when applied to distribution systems.  These options result in a reduction in the total installed capacity of the sources together with reduced continuous current and fault current ratings of conductors and interconnected apparatus.  The invention provides a switching network comprising six conducting branches, each branch containing at least one switching means such as a circuit breaker.  The branches are connected at their ends to form four 3-sided rings, each branch forming a side of and being shared by two of the rings.  As a result, four triple-connected nodes are formed at the end connection points of the branches while the connections between adjacent pairs of switching means within a branch form double-connected nodes.          These nodes serve as points for connection thereto of source/load elements, and each node is isolatable from the other nodes by the opening of a maximum of three of the switching means.
