Abstract: Abstract of the Disclosure Seize is prevented between metal surfaces exposed to high temperature and corrosive gases by an antiseize coating layer.  The coating comprises per 100 weight parts, about 10 - 30 parts chemically inert anti-seize particles that have a fusion point above about 100°C and are in the size range of from about 2 - 100 microns; about 5 - 25 parts of a polymeric binder resin that is adherent to metal surfaces; and the balance, a volatile solvent for the resin.  The liquid coating is applied by suitable means, and dried by evaporating the solvent.At least a layer of the particles remains dis-persed in the dried resin and provides the coating with its antiseize properties.

Abstract: HYDROMETALLURGICAL PROCESS FOR       THE RECOVERY OF LEAD                        Abstract A hydrometallurgical process is used to recover lead from a lead-bearing ore concentrate.  The lead-bearing ore concentrate is leached with a solution of cupric chloride in order to precipitate lead as lead chloride, produce elemental sulfur and substantially leave the balance of the ore concentrate sulfides in unreacted form.  The residue of the cupric chloride leach is leached with a brine solution in order to solubilize the lead chloride-to the exclusion of the balance of the residue.  There-after, the lead chloride is crystallized from the brine solution.  Elemental lead may be obtained by the reduction of the lead chloride crystals.     The present process avoids air pollution problems inherent to smelting processes, allows for a high re-covery of lead of 97% or greater and allows for the direct production of a high purity lead.

Abstract: ABSTRACT OF THE DISCLOSURE            The electrodes of the steam generator are each formed as a horizontally extending disk to receive descending water jets from a distribution chamber above the electrode as well as with openings to direct water jets downwardly onto a collecting grid.  The current flows from the electrodes through the water jets to evaporate part of the water to steam.  Movable inter-ceptors are also mounted in the vessel to intercept the water jets for partial loads.  The invention results in a reduced overall height of the generator.  In a particularly useful embodiment,  the water distribution means are movable to adjust the number of water jets which impinge on the electrodes while the collecting means for intercepting the excess water are stationary.  Each collecting means is also located out of vertical alignment with the respective electrode.  The distribution means are fixed to a rotatable pipe which serves to move the distribution means and through which water can be fed to the distribution means.  The latter embodiment results in a still further reduction of the overall height of the generator.

Abstract: PROGRAMMABLE LOGIC ARRAY SYSTEM INCORPORATING JOSEPHSON DEVICES                    ABSTRACT            A Programmable Logic Array (PLA) system which utilizes Josephson devices and the noninverting capabilities of these devices is disclosed.  The disclosed PLA system includes a personalized Read Only Memory (ROM) which is adapted to store the applied input signals as well as the output signals which are a logic function of the input signals. As soon as outputs from the ROM are available, an interface circuit which may be timed or untimed, inverting or noninverting provides output signals which can be utilized to drive other logic circuits or to act as inputs to another personalized Read Only Memory (ROM).  The latter provides another logic function of the inputs at its outputs. Again, the outputs may be used directly or applied to another interface circuit which itself may provide inverted or noninverted outputs.            Like the first mentioned ROM, the second mentioned ROM is capable of storing its inputs and the re-sulting outputs which are some logic function of the inputs as a result of the ROM personalization The ROM's involved utilize memory cells which are programmable Josephson junction devices operating in a liquid helium environment.          The programmable logic array system is disclosed in a full adder embodiment which id dc powered. A similar hybrid embodiment using both ac and dc power is also shown. The resulting system using high density ROM's provides high speed logic using rela-tively standard loop circuits which minimize the effect of the presence of resonances of known random logic circuits.

Abstract: LOW-VISCOSITY, HIGH-NSI, HEAT-GELLING SOY ISOLATES     ABSTRACT OF THE DISCLOSURE     The present invention provides high NSI dry vegetable protein isolates which may be effectively utilized to replace egg albumin and/or miIk caseinates in food recipes.  The isolates are characterized as having an NSI of at least 90, substantially free from vegetable protein hydrolyzates, capable of forming insoluble heat-set gels and having aqueous Brookfield viscosities substantially lower than those which are obtained from conventional undigested vegetable protein hydrolyzates.          The relatively neutral pH extraction conditions in the presence of sulfurous ions, coupled with its recovery without chemically or enzymatically hydrolyzing the protein constituents affords an  effec-tive method for manufacturing these unique isolate products.  The isolates may be used to directly replace either casein or egg albumin in a wide variety of food recipes.

Abstract: INDEPENDENT HANDLING OF I/O INTERRUPT REQUESTS   AND ASSOCIATED STATUS INFORMATION TRANSFERS                 ABSTRACT OF THE DISCLOSURE    In a tightly coupled multiprocessing system wherein plural central processing elements share an operating system (supervisory program), a main store, and a multipath I/O channel processing facility for linking to peripheral devices, and in which the channel processing facility contains a single unique subchannel for each device regardless of the number of paths available for connecting to the device, apparatus disclosed herein ensures that a central processing element which attempts to start an operation of the device will have reference to the latest pertinent status even if another central processing element is simultaneously attending to an interruption associated with such status.  This apparatus retains status information in the subchannel, along with an indication of its retention, while the interruption is being handled in the central complex.  The central complex is required to examine and reset the retention indication, and recover any associated status, before it can stimulate the channel facility to start the device.  The apparatus for performing these operations includes means in the central complex for executing the examining, resetting and recovery operations in response to a special program instruction Test Subchannel (TSCH).

Abstract: ABSTRACT      A carrier adapted to move between a movable vessel, such as a boat, and a stationary platform.  The carrier has an extendable and retractable intermediate uphaul line adapted to be connected to a crane on the platform.  It also has a downhaul line connected between the carrier and the vessel.  When the carrier is being lifted from the vessel, the downhaul line is payed out at a controlled rate with the uphaul line extending and retracting to keep the carrier out of contact with the vessel which may be rising or falling due to wave action of the water.  At a predetermined elevation, the tension in the downhaul line is decreased so that the uphaul line retracts to move the carrier out of the area of possible contact with the vessel.  The reverse operation is followed to move the carrier from the platform to the vessel.   Thus, the invention makes it possible to transfer from a vessel  personnel or cargo without risking that such personnel and cargo will be impacted if the vessel is carried upwardly by a large wave shortly after the liftoff of the personnel or cargo from the vessel.
