Abstract: ABSTRACT             The gellation of polysaccharide gums such as guar or locust bean gum is inhibited by gelatin hydrolysates, at alkaline pH.  Formulation of gum, gelatin hydrolysate and alkaliniser are reconstituted by shaking with water, and are easily imbibed.  The inhibition is reversed by pH change in the stomach allowing gellation to occur.  The formulation is useful in treatment of hyperchole-steraemia, gastric disorders and as an adjunct to insulin therapy.

Abstract: ABSTRACT    DISTRIBUTED DATA TRANSFER CONTROL FOR PARALLEL PROCESSOR ARCHITECTURES    An apparatus for distributing the control of data transfers within single instruction stream multiple data stream processors.  Each of the parallel processors or arithmetic units is coupled to a dedi-cated local memory.  A main memory provides storage of system data,  Each dedicated local memory and the main memory are coupled to a bus interface unit. Each bus interface unit is coupled to a common data bus for the transfer of data between the main memory and the dedicated local memories.  Each bus interface unit provides the control functions required to transfer data between the common data bus and the main or local memory to which it is coupled.  One bus interface unit is designated the resource controller.  The resource controller performs all of the functions of a bus interface unit and also provides the system level func-tions of supplying clock signals and performing bus arbitration.  Each bus interface unit is capable of managing transfers to and from its associated memory thereby distributing control of the multiple data streams eliminating the potential problems associated with requiring a single controller to manage these parallel data transfers.

Abstract: ABSTRACT           A multiprocessor system has a plurality of proces-sors and a memory unit which are interconnected through a common bus.  Each processor communicates with the memory through the bus.  Communication among processors is also ef-fected by storing in memory, into memory zones the messages intended for the several processors, each dedicated to one processor but accessible to all the processors.  This operation is performed using the common bus and the normal memory communication procedure.  A notify signal is sent on the common bus and identified by the only processor for which it is intended.  The notifying signal is memorized by the notified processor without interrupting its continued operation and is taken into account in a completely auto-nomous way as to the notifying processor.  The identification of the notifying signal causes the notified processor sub-sequently to access the memory unit and read out the message.

Abstract: ABSTRACT A floor feeder for movement of discrete mechanical parts from within a conical hopper to a remote deposit location includes a direct, gravity-feed conical hopper whose lateral cross section has a curved perimeter shape.  At an elevated point above the conical hopper, a first rotating drive member is located and at a second location below the conical hopper, another cooperating drive member is located.  Extending around these two drive members is an endless conveyor belt with a plurality of spaced apart flights extending outwardly from the surface of the belt.  The conical hopper has a slot-like opening extending the full length of one side and the conveyor belt passes through this opening and is substantially flush with the opening.  As the conveyor belt passes through the opening of the hopper, discrete mechanical parts are collected and brought to the uppermost point of the conveyor system where they are emptied from the conveyor belt as the belt begins its return path.  By arranging the conical hopper with a continuously curved perimeter shape in cross section, the bridging effect frequently occurring with flat-sided hoppers is eliminated and a smooth flow of parts results.

Abstract: Title METHOD AND APPARATUS FOR FIELD FLOW FRACTIONATION                             Abstract of the Disclosure The method described is useful in field flow fractionation techniques for reducing separation times and improving the convenience and accuracy of measuring sizes or molecular weights of particulates.  In field flow fractionation, the particulates (particles or macromolecules) are subjected to a force field and a mobile phase while passing through a flow channel.  This field strength is decreased exponentially as a function of time.           Alternatively the flow velocity is increased exponentially as a function of time.  The initiation of the change in field strength or flow velocity may be delayed a period of time.  If this time delay is made equal to the time constant of the exponential decay, the range of particulate retention time that is linearly related to the logarithm of the particle size or molecular weight is increased.       An apparatus for implementing the method is also described and teaches the use of a function generator for providing the desired exponential decay and delay time.  The apparatus is described in implementations involving a force field.
