Abstract: ABSTRACT OF THE DISCLOSURE             A process is provided for preparing hydrophobic agents which may be combined with inorganic binding agents prior to molding. The process involves slaking caustic lime with an organopolysiloxane and water in which at least one mol of water is present for each mol of CaO, the organopolysiloxane in the emulsion having an average of from 0.8 to 1.8 SiC-bonded hydrocarbon radicals selected from the group consisting of alkyl radicals having from 1 to 16 carbon atoms and phenyl in the presence of a protective colloid and thereafter dried, the improvement which comprises: adding to the above mixture at least one alkyl metal salt of an acid having the formula R(O)aSO3H in which R is a monovalent hydrocarbon radical having up to 50 carbon atoms and which may also con-tain oxygen and nitrogen atoms and a is 0 to 1. The agents can be added to the inorganic binding agents at any time and can be uniformly dispersed without danger of demulsification. While they are easily wetted with water, the molded objects or coatings have a great degree of water repellency.

Abstract: ABSTRACT:  A high voltage dropout type expul-sion fuse has a lower trunnion assembly mounted on one end and a fuse release assembly mounted on the other end thereof.  To assure the proper positional relation-ship between the trunnion assembly and the fuse release assembly, the fuse housing has a locating boss at one end adapted to engage and position the trunnion assembly and a positioning slot formed in the other end adapted to engage and position the fuse release assembly.  The locating slot and boss must be properly positioned with respect to one another to assure the proper positional relationship of the trunnion assembly and the fuse release assembly.  The lower locating boss is integrally formed on the wall of a metallic ferrule by extruding a portion of the wall into the cavity of a die to form an integral locating boss.  This integral boss cannot cause the leakage of moisture into the interior of the fuse.  The boss is formed by first determining the desired location of the boss by measuring the correct positional relation-ship with respect to the locating slot, positioning a die having a cavity at a position where the boss is to be located at the exterior of the ferrule wall, and extruding a portion of the wall of the ferrule into the cavity to form the locating boss.  Also, various non-circular shapes of bosses can be conveniently formed in this manner by merely changing the shape of the die and punch.  This is advantageous if it is desired to prevent non-compatible end fittings, e.g. trunnion assemolies, from being used.

Abstract: ABSTRACT  OF  THE  DISCLOSURE      A continuous stream of liquid is drawn from a machine tool system settling tank whilst the system is shut down, aerated outside the tank and returned to the tank.   The aerator extends upwards from the liquid in the tank and comprises a series of down-wardly sloping surfaces below a pyramid-shaped deflector which is coaxial with and below the inlet of the aerator.   The upper end portion of each downwardly sloping surface extends below a space formed at the lower end of the surface immediately above.   A fresh air inlet communicates with each such space.   The bottom downwardly sloping surface extends below the level of liquid in the tank.   The stream of liquid is directed onto the apex of the deflector by which it is converted into a spray which falls onto and cascades down the downwardly sloping surfaces inter-mingling with fresh air as it passes through the spaces so that the liquid is aerated.   The aerated liquid is returned to the tank gently by the bottom downwardly sloping surface.

Granted: 1982-09-21
Abstract: ABSTRACT OF THE DISCLOSURE           A pick-up device for reading out information which has been recorded on a magnetic medium.  The device comprises a sub-strate and a layer of soft magnetic material overlying a surface of the substrate, the easy axis or direction of magnetization being normal to the surface and the magnetic material having properties capable of having magnetic bubble domains generated and propagated therein, so that when the pick-up device is used to read out infor-mation from a magnetic medium, patterns of magnetic domains are formed in the layer of magnetic material corresponding to the patterns of the recorded information.  Although the magnetic material is of the type capable of having magnetic bubble domains generated and propagated therein, there is no need to provide the usual bias field for maintaining the bubble domains or for provid-ing domain-transport or domain-annihilating fields.  In one use of the pick-up device, light is transmitted through the substrate and through the layer of magnetic material to be reflected from a layer of light-reflective material back through the magnetic material and the substrate, whereby the polarization of the reflected light is rotated, relative to the polarization of the transmitted light, by an amount determined by the patterns of magnetic domains formed in the layer of magnetic material.  Hence, the recorded information can be optically read from the magnetic medium.  In another use of this device, a magnetoresistive head is disposed on the substrate, the resistance of this magnetoresistive head being varied as a function of the patterns of magnetic domains formed in the layer of magnetic material.

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