Abstract: METHODS AND APPARATUS FOR RECOVERING SOLVENTS     ABSTRACT         Methods and apparatus for recovering hydrocarbon sol-vents evaporated during the curing of solvent borne coatings in an oven include supplying an inert gas to the vicinity of the oven entrance and exit to substantially exclude oxygen there-from while safely maintaining a solvent vapor partial pressure within the oven of at least 75% of the lower explosive limit of such vapor in air.  The oven atmosphere is exhausted and passed to a condenser to enable recovery of at least 85% of the solvent vapor as a liquid.  Preferably, condensation of the solvent vapor is effected by heat exchange with liquid nitrogen which is effective to vaporize the liquid nitrogen to produce nitro-gen gas which may then be utilized to exclude oxygen from and to inert the oven.

Granted: 1981-12-01
Abstract: ABSTRACT OF THE DISCLOSURE A logic system is disclosed for using a memory device of the serial read type having redundant elements in excess of the nominal memory size and consists of a Programmable Read Only Memory having a defect map programmed into it with respect to the associated memory device, a shift register of a prede-termined length equivalent to the maximum number of allowable defects, a multi-plexer associated with the shift register, a position counter for controlling the multiplexer and, finally, appropriate logic to control the system.  This system is disclosed in connection with a bubble memory system of the field access major loop - minor loop type having extra minor loops.  As defects are encountered in writing, data is shifted through the shift register while the multiplexer is incremented to the proper output position of the shift register based on the number of encountered defects.  As data is read, an analogous re-verse to writing operation is performed with the multiplexer being decremented. In either writing or reading, the multiplexer will never be shifted more than one position for each data bit.

Abstract: WIRE DRAWING DIE AND METHOD OF MAKING THE SAME        ABSTRACT OF THE DISCLOSURE      A wire drawing die employing a synthetic hard, wear-resistant material, such as a polycrystalline aggregate of synthetic diamond or a polycrystalline cubic boron nitride includes a metal casing having flat, parallel front and back sides.  A cylindrical cavity is formed in the front casing side having a flat bottom, the side wall of the cavity being undercut adjacent the bottom.  A first layer of metal powder is deposited in the casing cavity covering the bottom and the undercut.  An annular metal blank having flat opposite sides and a core formed of the hard, wear-resistant material is placed on the first metal powder layer and adhered thereto, the core being concentric with the cavity.  A second layer of metal powder is deposited in the cavity covering the first layer and the blank, the metal powder of both layers having a melting point lower than the thermal degradation temperature of the core.  A cylindrical cavity having a flat bottom is formed in one end of a cylindrical plug, the inside diameter of the plug cavity adjacent the bottom being greater than that at the one plug end.  The plug is inserted in the casing cavity with the plug cavity facing the second metal powder layer until the plug cavity bottom engages the second metal powder layer, and pressure is applied to the plug to compress the metal powder layers.  The casing is then heated for a time and at a temperature sufficient to melt the metal powder, but at a temperature less than the thermal degradation temper-ature of the core thus forming a body of molten metal which encapsulates the blank.  The pressure and heating is then terminated and the casing is cooled to solidify the metal body to secure the plug and blank in the casing cavity.  Counter-sunk openings are formed in the back side of the casing and the other end of the plug which respectively extend through the metal body to the core, and a die opening is drilled through the core communicating between the countersunk openings.

Granted: 1982-05-18
Abstract: Abstract of the Disclosure A method for the processing of titanium-containing feedstock for obtaining high-titanium slags and alloyed low-carbon cast iron consists in that titanium-containing feedstock is melted in the presence of a reducing agent-anthracite, as well as in the presence of metal titanium and/or a titanium-containing material which comprises tit-anium alloys or residue of unchlorinated titanium slags which is formed in the production of titanium tetrachlor-ide and consists of titanium slag and petroleum coke, used in an amount from 7 to 13% by weight of starting compon-ents. The melting is conducted with the formation of gas-eous phase over the surface of starting feedstock, the temperature of the gaseous phase being from 500 to 900°C and pressure from 0.1 to 0.2 mm H2O.      The method enables the production of high-titanium slags containing 92-94% by weight of TiO2 and less than 5% by weight of FeO. Rate of titanium extraction is 97-98%. The use of the method according to the invention brings a solution to such important problem as utilizat-ion of offgrade titanium wastes which could not be sold so far.

Abstract: ABSTRACT A small, low cost, programmable controller is described capable of solving user programs represented in networks having up to seven rows and eleven columns.  Its new features include a column solver to provide efficient and fast solution of the user control network.  The programmable controller also solves calculate functions having multiple outputs to facilitate use of the output information in the control program.     A programming panel using a CRT display shows one or more selected control networks and, in conjunction with the central processing unit of the programmable controller, provides for the insertion of networks between two existing networks.  Since the networks are solved by the controller mainframe in a sequential fashion, this network insertion allows the user to optimize his or her control program when solution order of the networks is important.     The output coil numbers of network rows may also be assigned by the user independent of their placement in the control program to further facilitate programming the controller.  The programming panel includes a movable cursor on the CRT display which, in conjunction with a light-emitting diode (LED), allows the user to monitor the real-time power flow at any particular point in the displayed ladder diagram network.  Specialized search features can also be specified by the;user to simplify monitoring and de-bugging the control program.

Abstract: WELL SCREEN MOUNTING ARRANGEMENT                       ABSTRACT         Mounting arrangement for a pipe base well screen utilizes a weld for joining one end of a cylindrical screen member to the outer surface of an internal pipe member which has perforations along a portion of its length underlying the well screen.  The opposite free end of the screen mem-ber includes an elongated sleeve portion which supports an internal elastomeric O-ring member in a groove.  The O-ring seals the screen member to an unperforated portion of the pipe base and permits the pipe to be subjected to substantial tensile and torsional stresses without destroying the screen as often  happens when a screen is welded at each of its ends.

Abstract: 48,550 ABSTRACT OF THE DISCLOSURE           A high voltage seismic bushing charged with an insulating material has a porcelain tube having an adapter rigidly connected to one end of the tube.  The adapter is flexibly  connected  to  a mounting  flange  such  that  the porcelain tube is free to move relative to the mounting flange  in  the  event  of  an  earthquake.   The  means  for flexibly  connecting  the  adapter to the mounting flange utilizes a spring mechanism to absorb the energy through friction to attenuate the movement of the porcelain tube. A resilient buffer member is interposed between the adapt-er  and  the mounting  flange  to provide a predetermined spacing  therebetween and  absorb  the  impact  due  to the movement of the adapter relative to the mounting flange. A sealing member seals the interface between the adapter and  the  mounting  flange  for  containing  the  insulating material charged therein.
