Abstract: DE LA RUE GIORI S.A.                  LAUSANNE /Switzerland "DEVICE FOR FASTENING ONE EXTREMITY OF A SOFT  AND FOLDINGPROOF BLANKET ON A CYLINDER OF A ROTARY PRINTING MACHINE"                 ABSTRACT OF THE DISCLOSURE     The cylinder is provided with a radial insertion slot forming in its inner portion a widened cavity. One of the walls of the slot is provided with a receiving groove of which the median plane forms with the wall of the slot an acute angle of the order of 30°. The folded end reinfor-ced by a spring-steel blade of the blanket is inserted into the slot and thrusted by using a thin piece of sheet-metal or a spatula until, due to the return force of the blanket, it engages the opening of the groove. Then, the blanket is pulled outwards so that the reinforced end penetrates into the groove. Subsequently, the second end of the blanket is attached in the known fashion to a stretching pivot. The length, in the peripheral direction, of the bottom of the widened cavity is greater than the width of the folded end of the blanket, and the width of the outer portion of the radial slot is smaller than the width of the folded end.

Abstract: ABSTRACT OF THE DISCLOSURE       An internal gate rotary vane fluid meter which has markedly improved performance as a result of precise control over the geometry and dimensions of the rotating elements and the fluid flow path.  In particular, the outer diameter of the gate is maximized and the inlet and outlet passages of the meter are shaped to perpendicularly intersect the rotor vanes when the vanes are sealing against the respective ends of the meter crescent.  Furthermore, the inlet and outlet passages each have a total cross-sectional area substantially equal to a vane area to provide substantially constant fluid velocity.

Abstract: Abstract Of The Disclosure A process for the gaseous reduction of iron ore to sponge iron in a vertical shaft, moving bed reactor wherein a hot gaseous mixture of hydrogen and carbon monoxide is used to reduce the ore.  It has been found unnecessary to use the external catalytic reformer of prior art processes to reform the methane and other hydrocarbon constituents of the natural gas commonly used as a source of gaseous reductants.  By establishing a reducing gas recycle loop to which make-up natural gas and steam are fed in the proper proportions, the product sponge iron in the reactor can be used to catalyze hydrocarbon reformation, provided that the carbon content of the recycled gas is maintained low by removing carbon dioxide therefrom.  Where pure methane is employed, steam/methane molar ratios within the preferred range of 1.4:1 to 2.2:1 are used.

Abstract: ABSTRACT OF THE DISCLOSURE:     A multipurpose apparatus for drilling, engraving and carving ophthalmic lenses.  The apparatus comprises a base in which is mounted an electrical motor, and a tool holder is connected to the shaft of the motor for detachably mounting a drilling, engraving or carving end mill above the upper surface of the base.  A working support is also mounted on the upper surface of the base for maintaining and supporting the lenses in the various positions in which they must stand in order to be easily drilled engraved or carved.  The working support comprises a platform detachably mounted onto the upper surface of the base, and a guide holder rigidly mounted onto the platform in parallel relationship with respect to the tool holder.  The support also comprises a L-shaped tube having one end fitted into a central hole provided in the platform for giving room to the tool holder, and the other end connected to the guide holder.  The tube has an upwardly extending portion within internal diameter and a height sufficient to receive the tool holder while allowing the end mill mounted thereon to project outwardly from the tube through a small opening. The tube also has a perpendicularly extending portion from the upper surface of which projects the end mill, this upper surface being useful for supporting a lens when the same is drilled, engraved or carved with the end mill.  The apparatus may advantageously be connected to a vacuum source for sucking out particles resulting from the drilling, carving or engraving operation through the small opening from which projects end mill and the upwardly expanding portion of the L-shaped tube.  The apparatus may also comprise one or more lens guides adjustable mounted onto the guide holder for laterally guiding or retaining the lenses with respect to the end mill.

Abstract: ABSTRACT OF THE DISCLOSURE A straight-through three reactor system and pro-cess produces acceptable levels of sulfur recovery from acid gas at a cost significantly less than that required for a standard modified four reactor Claus system.  The system includes two conventional Claus reactors and one cold bed adsorption (CBA) reactor in series.  Four conden-sers are provided, one disposed before each of the cata-lytic reactors, and one disposed after the CBA reactor. The system is designed to operate either in a recovery mode or in a regeneration mode.  In the recovery mode, the reactors are in series and the last reactor is operated below dew point of sulfur (CBA reactor).  In regeneration mode, effluent from the third condenser is heated in a first heat exchanger where effluent from the first cata-lytic reactor is used as the heat source.  Sulfur is vaporized in the CBA reactor and is recovered in the fourth condenser.  Effluent from the fourth condenser is then passed to an incinerator.

Abstract: Abstract of the Disclosure:  The racemization of optically active aminoacids (including their N-acyl derivatives) by heating with carboxylic acids takes place particularly readily with carboxylic acids of low volatility.  Only catalytic quantities of acid are needed; it is advantageous to use equimolar quantities or an excess, which serves as a diluent.  A reaction mixture from an enzymatic racemate resolution can be heated directly for the purpose of racemization, after separation of the L-aminoacid and the water.

Abstract: EXPLOSION PROOF ELECTRICAL CONNECTOR  SYSTEM WITH QUICK POWER DISCONNECT          ABSTRACT OF THE DISCLOSURE         An electrical connector system, particularly one that connects armored electrical cables for oil wells through an upper surface connector that is mated to a feed-through mandrel, automatically operates a circuit breaker in the main power circuit as the upper connector is unmated from the mandrel.          A pair of relay (R) wires are carried with the main power conductors through the upper connector.  A set of relay (R) contacts, preferably pins and sockets, electrically connect the R wires between the connector and the mandrel.  The contacts in the mandrel are wired together.  Unmating the connector withdraws the R pins from their sockets which trips a relay or otherwise operates the main circuit breaker.  Power (P) contacts, preferably pins and sockets, for the main power conductors are longer than the R pins so that power in the main conductors is shut off before arcing can occur. Preferably this "quick disconnect" relay circuit is used in conjunction with an improved lip seal formed on the mating end of a resilient insulating body filling the connector.  The inner diameter of the resilient lip is less than the outer diameter of the mating portion of the mandrel to stretch the lip seal and thereby establish a very tight fit when the connector is attached to the mandrel.  The lip seal isolates the interior of the connection site from fluids surrounding the connector and is sufficiently long that it continues to seal even during uncoupling to prevent an explosion due to arcing at the R contacts.
