Abstract: TITLE            CONTROL SYSTEM FOR AUDIO-VISUAL PROJECTOR       ABSTRACT OF THE DISCLOSURE         A system for the control, selection and synchroniza-tion of the movement of magnetic tape and filmstrip in a film projection system which may include a sound program.  Film advance is synchronized with the sound reproduction by means of recorded signals on the magnetic tape which unambiguously specify the filmstrip frame number appropriate to the magnetic tape sound program.  Means are provided to allow the operator to rapidly access a particular filmstrip frame by specifying its number.  When a sound program is included, the invention assures automatic synchronization of the sound program with the filmstrip frame.

Abstract: Abstract of the Disclosure A multiprocessor system the kind in which two or more separate processor modules are interconnected for parallel processing includes two redundant interprocessor buses dedicated exclusively to interprocessor communication.  Any processor module may send information to any other processor module by either bus.  The buses are shared in use by the processor modules on a time-sharing basis.  Use of each bus is controlled by a special bus controller.  The multiprocessor system includes an input/output system having multi-port device controllers and input/output buses connecting each device controller for access by the input/output channels of at least two different processor modules.  Each device controller includes logic which insures that only one port is selected for access at a time.  The multi-processor system includes a distributed power supply system which insures uninterrupted operation of the remainder of the multi-processor system in the event of a failure of a power supply for a part of the system.  The distributed power supply system includes a separate power supply for each processor module and two separate power supplies for each device controller.  Either one of the two power supplies provides the entire power for the device controller in the event the other power supply fails.          The distributed power supply system permits any processor module or device controller to be powered down so that on-line mainten-ance can be performed in a power-off condition while the rest of the multiprocessor system is on-line and functional.  The multiprocessor system includes a memory system in which the memory of each processor module is divided into four logical address areas -- user data, system data, user code and system code.  The memory system includes a map which translates logical addresses to physical addresses and which coacts with the multiprocessor system to bring pages from secondary memory into primary main memory as required to implement a virtual memory system.  The map also provides a protection function.  It provides inherent protection among users in a multiprogramming environment, isolates programs from data and protects system programs from the actions of user programs.  The map also provides a reference history information for each logical page as an aid to efficient memory management by the operating system.          The multiprocessor system includes in the memory of each processor module an error detection and correction system which detects all single bit and double bit errors and which corrects all single bit errors in semiconductor memory storage.

Abstract: ABSTRACT           Vitamin B12 in liquid samples, such as human serum or human plasma, is assayed by a competitive binding technique using intrinsic factor and certain labelled vitamin B12 derivatives.  The labelled derivatives are formed from the (d)-monocarboxylic acid isomer of vitamin B12, which isomer is free from other monocarboxylic acid isomers (and derivatives thereof) of vitamin B12, by binding to the (d)-isomer, via the carboxylic group, a compound which is itself a label (e.g. an enzyme) or which comprises a label (e.g. a fluorophore), or to which a label is attached (e.g. a histidine ester to which 125I is attached).  The labelled derivatives of the (d)-monocarboxylic acid of vitamin B12, free from other isomeric monocarboxylic acids and derivatives, are novel and constitute one aspect of the invention.

Abstract: SIMULTANEOUS LEACHING AND CEMENTATION          OF PRECIOUS METALS            Abstract:     A method for the recovery of precious metals such as gold and silver from various ore types is disclosed which involves subjecting a slurry of the ore to a simultaneous leaching and cementation process with a reagent such as an alkaline cyanide solution providing for the leaching require-ment and a reducing metal affording cementation.  The reducing metal is selected from the group consisting of cadmium, copper, iron, lead, molybdenum, tin, zinc and alloys and mixtures comprising at least two of these metals.  The simultaneous leaching and cementation occur under conditions controlled to afford at least partial dissolution of the precious metal values from the ore, whereby continuous transfer of these values from the ore onto the surface of the reducing metal is promoted.  The resultant cementation product, i.e., the re-ducing metal with precious metal values cemented thereon, is separated from the ore slurry and subjected to a subsequent precious metal recovery step by conventional methods.

Abstract: LIFT TRUCK PAPER ROLL CLAMP HAVING AUTOMATICALLY ADJUSTABLE ROLL POSITIONER FOR ENGAGING ROLLS OF              DIFFERENT DIAMETERS                 ABSTRACT OF THE DISCLOSURE     A lift truck load clamp, for handling cylindrical loads such as paper rolls, having an auto-matically adjustable load positioner extending between the clamp arms which moves forwardly in response to closure of the clamp arms and rearwardly in response to opening thereof to assist the lift truck operator in positioning the clamp arms with respect to rolls of different diameters such that the contact pads of the clamp arms automatically grip such differently-sized rolls in diametrically-opposed relation.  The load positioner is particularly adapted for use with clamps wherein both clamp arms are movable with respect to a clamp frame, because each end of the positioner is separately movable forwardly or rearwardly with respect to the frame in response to movement of the respective adjacent clamp arm.  The positioner is also well adapted for use with clamps of the type wherein the clamp arms can be moved transversely in unison to handle a paper roll in different transverse positions, due to the fact that the load positioner is movable transversely in unison with the clamp arms.  The posi-tioner is flexibly conformable to the cylindrical sur-faces of paper rolls of different diameters to avoid damage to the fragile surfaces thereof.

Abstract: ABSTRACT     An antenna of the geodesic lens type is disclosed.          The antenna structure is based on optical principles and provides wide angle scanning of a narrow beam.  The exact shape of the domed structure 10 is found by solving an integral equation and results in nearly perfect focus in the scan plane.  A dielectric loaded flared horn 20 is attached to the feed circle 15 of the domed structure and focusses energy in the plane orthogonal to the scan plane.  The cross sectional shape of the outer curvature of the dielectric 21 is elliptical.  Since the structure is circularly symmetrical, constant beam shape, wide angle scanning, and a rapid scan rate are possible.
