Abstract: Abstract An apparatus and method for separating particles from a fluid, particulate suspension by flotation in a centrifugal field.   The apparatus  includes  a  vertically  oriented, cylindrical  vessel  having  a  tangential  inlet  and  a tangential outlet. The particulate suspension is introduced into the vessel through the inlet and swirls around the inner surface of the vessel in a thin fluid layer. Air is sparged through a porous wall formed in the vessel and into the thin fluid layer of the particulate suspension. Small bubbles are generated at the surfact of the porous wall. The directed motion of the particles in the thin layer of particulate fluid suspension results in a high probability for collision and a rapid flotation.  The air bubbles and particles form bubble/particle aggregates which migrate towards the axial center of the apparatus and into a froth phase in the core of the  apparatus.   The  particle-containing  froth  travels upwardly, countercurrently to the thin fluid layer, and is removed coaxially through a vortex finder.

Abstract: NEEDLE-LOADING MULTIPLE BARREL SYRINGE   Abstract of the Disclosure A multiple barrel syringe for selective delivery of a plurality of fluids through a single needle is adapted to be loaded with each of said fluids through the needle thereof. The syringe body includes a pair of fluid-retaining bores, each containing a plunger and each communicating with the single needle through restrictive conduits in which respective flexible sealing valves are interposed.  As each plunger is depressed, the respective valve is depressed and distorts under pressure of the fluid, allowing the fluid to flow to the needle.  For filling each bore through the needle, a plunger is manually depressed to compress and distort the respective valve, enabling fluid to flow from a container through the needle and through the unob-structed conduit to the selected bore in response to raising of the plunger.

Abstract: ABSTRACT OF THE DISCLOSURE   For switching or, respectively, distributing broadband communication signals in message switching systems, broadband switching matrix networks having crosspoint circuits realized in an ECL technology and which are formed by controllable multiplexers is provided.  The controllable multiplexers are mutually interconnected to form multistage crosspoint pyramids respectively exhibiting an outgoing line and a plurality of incoming lines, whereby the controllable multiplexers of a respective plurality of crosspoint pyramids are combined on a chip module.  The chip module may be a master slice module. An additional transfer crosspoint in the form of a 2-bit multiplexer can be provided at the tip of the pyramid at each crosspoint pyramid, the additional transfer crosspoint also being connectable to the pyramid chip of a further crosspoint pyramid in order to therefore introduce a corresponding expansion of the switching matrix network.  Moreover, when switching or distributing communication signals in the form of frequency-modulated signals and given non-through connection of such a communication signal to the outgoing terminal of the crosspoint pyramid, an unmodulated carrier can be supplied over such an additional transfer crosspoint in order to therefore counter crosstalk interference. The individual crosspoint pyramids can be driven by appertaining drive registers whereby a clock decoder enables the selection of the respective crosspoint pyramid.

Abstract: PROCESS FOR IMPROVING POLYMER FIBER               PROPERTIES AND FIBERS PRODUCED THEREBY     Abstract of the Disclosure A method is provided for treating polyester, and acrylic polymer fibers or fibrous structures made thereof to permanently improve the antistatic, hygroscopic, dye receptive, soil release, inter-fiber adhesion and bonding properties of the fibers and structures.  The method involves contacting the fibers with an aqueous solution containing at least one unsaturated monomer and having an acid pH and a temperature between about 60°C and about 100°C.  After allowing the solution to uniformly disperse among the fibers, so that the monomer intimately contacts the fiber surfaces, polymerization of the monomer on the fiber surfaces is initiated by a polymerization initiator for the monomer, and the polymerization is continued for a sufficient time to allow substantial graft polymerization of the monomer on the fibers to modify the surface proper-ties of the fibers. The fibers are preferably scoured prior to the treatment process, and after polymerization the fibers are rinsed to remove acid and excess homopolymer prior to dyeing and/or further processing of the fibers. The fibers may be in the form of knitted, woven or non-woven fabrics, and may include mixtures of fibers such as acrylic yarns and nylon filaments or polyester and cotton staple fiber blends.

Abstract: TITLE OF THE INVENTION    A Clock Recovery System for TDMA Satellite Communication System ABSTRACT OF THE DISCLOSURE    A clock signal in a TDMA burst signal is recovered by using the frequency and phase information extracted by taking a moving average of plural bursts received previously from the same earth station.  The system has storage means for storing frequency and/or phase information of a moving average of plural bursts received previously, and clock signal necessary to demodulate the present burst is recovered by using output of said storage means.  Thus, the synchronized clock signal for demodulating the received burst is obtained in a short time, or even a clock recovery bits in a burst may be removed.  The establishment of the synchronized clock signal is indicated by a synchronization circuit which provides the establishment signal for each burst after receiving a predetermined plurality of bursts from  the same earth station.

Abstract: PUMP ACTUATOR                       ABSTRACT   An actuator and sac are described for use in a pump having a pump chamber whose contents are expelled by movement of a pair of pusher plates toward one another.  The actuator includes opposed solenoid armatures which are operable for movement between open and closed positions.  The armatures are each operatively connected to an associated pusher plate by a main spring which is attached at one end to the back end of the armature, extends through a front-to-back slot in an armature core, and is connected at its opposite end to the pusher plate.  A pair of preload springs carried on each armature and disposed on either side of the associated main spring acts to hold the main spring in a prestressed condition prior to solenoid actuation.  With closure of the armatures, and with the sac still in an expanded condition, the main springs are disengaged from the associated preload spring and placed in a more stressed, more planar configuration, with the increased stress in each main spring being relieved by movement of the pusher plates toward one another.  The sac has an annular side wall which is held in a rigid condition, and a pair of opposed circular walls, each joined to the annular side wall through a flexible annular wall portion.  A circular pusher plate acting against each circular wall has an initial deflection position at which the associated flexible wall portion in the sac takes the form of a circumferentially uniform roll having an outwardly convex, bulged cross sectional curvature.      The rolls in the sac maintain their circumferentially uniform, bulge-like character as the pusher plates are moved toward inwardly moved positions.

Abstract: ABSTRACT OF THE DISCLOSURE           A magnetic tape is simultaneously recorded with digital signals on one or a plurality of forward recording tracks and reverse recording tracks thereon as the tape travels in a predetermined direction.  The digital signals are reproduced from the forward recording tracks when the tape travels in a direction from one end to another end thereof, and the digital signals are reproduced from the reverse recording tracks when the tape travels in a direction from the other end to the one end thereof. The digital signals are recorded with the phase of the digital signals which are recorded on the forward or reverse recording tracks, relatively advanced with respect to the phase of the digital signals which are recorded on the reverse or forward recording tracks, so that solitary reproduced waveforms which are reproduced from the forward and reverse recording tracks respectively have substantially the same assymmetry of zeros or the same symmetry of zeros.  The first recording tracks are scanned upon reproduction in a direction opposite to the predetermined direction in which the tape traveled upon recording, and the second recording tracks are scanned upon reproduction in a direction which is the same as the predetermined direction in which the tape traveled upon recording.
