Abstract: "APPARATUS FOR THE GASIFICATION UNDER PRESSURE OF BITUMINOUS  COAL, ESPECIALLY OF FINE COAL IN A GENERATOR"     ABSTRACT OF THE DISCLOSURE        Apparatus for the gasification under pressure of bituminous coal, especially fine coal, comprising a generator which has a container to receive the coal to be gasified and a feed device which supplies the coal to the container, while keeping the container closed off so as to maintain the pressure in the generator.  The feed device includes a briquette forming device located on the container, and a continuously operable screw conveyor which feeds the coal to be gasified through the briquette forming device and directly into the container in the form of briquettes.  The feed device is encapsulated and, together with the fine coal and briquettes within it, forms a gas tight closure for the container to maintain the pressure therein.

Abstract: Abstract of the Disclosure A printing apparatus for an electronic calculator or the like comprises a first type wheel formed with mathematical operator symbols which is fixed to a spline shaft and a second type wheel formed with digits which is slidably mounted on the spline shaft for integral rotation.  A stepping motor rotates the spline shaft for character selection.  A carriage is connected to the second type wheel and is movable by a cable wound around drive and take-up spools to move the second type wheel along the spline shaft for serial feed. A single electrical solenoid actuates a printing hammer for printing and subsequently actuates a ratchet and pawl mechanism to serially feed the second type wheel by one character position in one reciprocation of the solenoid plunger.  A linkage initially connects the plunger to a first printing hammer associated with the first type wheel to print the mathematical operator and subsequently to a second printing hammer associated with the second type wheel to serially print digits from least significant to most significant.

Abstract: ABSTRACT    Process and apparatus for making a metal annular member of pre-cise tolerances and desired surface finish.  An external die has a continuous die surface of the configuration desired for the ex-ternal surface of the metal annular member and an annular ridge sur-rounding the inside of the die for seating one end of an annular sheet metal blank.  A first punch engages the sheet metal blank and drives it into the external die so as to reduce the external diameter of the blank and seat it against the ridge.  The precise tolerance of the die surface of the external die determines both the external and at least a portion of the internal dimensions pro-duced in the annular sheet metal blank.  The first punch is axially movable to an endmost position wherein substantially all of the blank has been forced into the die.  An ejector punch is positioned inside of the external die and operates to provide a portion of the forming die surfaces as well as to eject the completed workpiece.

Abstract: ABSTRACT               A diverter for use in pneumatic conveyor duct systems, particularly for conveying loose particulate material, has a rotor and two ends, the ends being preferably axially spaced from each other.  A least one switching conduit extends between the ends and is arranged to selectively communicate with different pairs of ports at the inlet and outlet side of the diverter.  The area of ports includes resilient annular seals arranged to  press against a counter-face of an end plate such that the seal is in engagement with the respective plate during the entire path of movement from one to another state of communication of the diverter.  A cutout in the end plate is provided to facilitate inspection or exchange of the annular seals, the cutout being of a sufficient size to uncover the seal on appropriate turning of the rotor.  A flat, supplementary seal can be used to assist the sealing function during the switching of the diverter.  The rotor may be produced as an enclosed, pressurized unit which is particularly suitable for pressure-type pneumatic conveyor systems.

Abstract: AN IMPROVED COOLING SYSTEM FOR      A GAS TURBINE ENGINE     ABSTRACT OF THE DISCLOSURE         A gas turbine engine having cooled rotor blades is shown wherein the coolant is delivered to a stationary chamber adjacent the blades.  A portion of the coolant is directed to seals between the stationary structure and the rotor and another portion is directed between adjacent rotor discs for entry through the downstream disc into the blades supported therein.  The portion flowing through the seals is prevented from flowing into the fluid directed to the discs.  Also, the coolant to the discs is given a velocity vector substantially equal to the velocity vector of the openings through the disc to the blade root to minimize pumping losses and temperature increases in the coolant during its delivery to the blade.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to electrical connectors and more particularly to apparatus for facilitating the coupling and uncoupling of a pair of mating electrical connectors.          In state-of-the-art electrical apparatuses, the various individual modules or functional groups of an apparatus are commonly electrically connected to one another by means of cables.  The cables are conveniently attached by means of electrical connectors.  In order to assure proper electrical connection, these electrical connectors must have a significant amount of contact pressure, which leads to a significant amount of friction, and thereby a signifi-cant amount of force is required to couple mating connec-tors or to separate mated connectors.  Due to the minia-turization of electronic systems, these connectors are often very small, and it has been very difficult to couple or uncouple the connectors without applying damaging forces to the connectors or the cables or circuit boards to which the connectors are mounted.  Accordingly, the present invention provides an apparatus consisting of a rack gear on one of the connectors and an engaging pinion member on the other of the connectors for facilitating the coupling and uncoupling of the connectors.  The pinion member in-cludes a lever which when moved in one direction, causes a rotation of the pinion and a corresponding movement of the rack pulling the two connectors together.  When the lever is moved in the other direction, the two connectors are pulled apart.
