Abstract: A Recoil Damper for a Reciprocating Member Abstract A recoil damper for a reciprocating member mounted in a housing includes a annular ring mounted-adjacent a flange formed on the reciprocating member, the annular ring mounted in a viscous fluid interior of the housing.  The annular ring cooperates with the flange of the reciprocating member to allow a relatively free flow of the viscous fluid around the flange upon motion of the reciprocating member in one direction and to restrict flow of the viscous fluid around the flange upon motion of the reciprocating member in the other opposite direction.

Abstract: 1.     Apparatus for the flotation of flocculated solid material in a liquid.                  ABSTRACT OF THE DISCLOSURE     Flotation apparatus for flocculated solid material has a flotation tank alongside a passage for upward flow of liquid carrying the solid material.  A wall of the passage on the side towards the tank has a top portion curved over to its free edge to provide a submerged weir over which the liquid passes from the passage into the tank.  To prevent turbulence in the liquid on passing over the weir and to prevent a preferential flow path in the flotation tank, the tank itself has, on its side towards the upward flow passage, a side wall which is generally spaced from the side wall of the passage but joins the latter wall away from the said free edge.  The tank side wall slopes downwardly away from the passage from a point located inwardly of the tank with respect to the free edge.

Abstract: VEHICLE FRAME AND BODY ALIGNMENT APPARATUS                    A B S T R A C T         An alignment checking and measuring apparatus for vehicle frame and body portions includes two or more meas-urement scale carriers which have connectors on opposite end portions thereof for attachment transversely to the vehicle.          One of the measurement scale carriers has targets movably mounted on the end portions and another of the measurement scale carriers has sighting instruments, such as laser beam emitting instruments, mounted on the end portions.  The measurement scale carriers are longitudinally spaced from each other.  Longitudinally aligning the sighting instru-ments with the targets  facilitates determination and correc-tion of any damaged or misalignment condition in the vehicle frame any body.  Comparison is made of the deviation, if any, in the parallelism of the lines of sight created by the longitudinally aligned targets and sighting instruments.          Angular deviation of the lines of sight to symmetrical points on the vehicle frame and body tends to indicate damage or misaligned conditions.

Abstract: Abstract A therapeutic composition and system suitable for extracorporeal treatment of whole blood comprises a dialyzable chemotherapeutic agent and a dialyzable fluorescable tracer means.  The removal rate of the fluorescable tracer compound from treated blood during hemodialysis is a function of the removal rate of unreacted chemotherapeutic agent present.  The residual chemotherapeutic agent concentration after hemodialysis is ascertained by measuring the concentration of the fluorescable tracer compound in a dialysate using fluorometric techniques.          The system includes a continuous confined flow passageway for communicating with a patient's cardiovascular system and defining an extracorporeal loop within which a portion of the patient's body fluid is circulated, a peristaltic pump means capable of transporting a substantially constant volume of a body fluid per unit time through the extracorporeal loop and occluding a segment of the extracorporeal loop, and a body fluid treatment means such as a hemoreactor situated within the occluded segment of the extracorporeal loop.          The hemoreactor comprises a length of tubing having a plurality of coils wound in a plurality of concentric helices to generate a centrifugally induced, transverse double toroidal secondary flow within the tube to gently mix the blood and therapeutic composition.

Abstract: ABSTRACT OF THE DISCLOSURE         In a radial piston pump, motor transmission the deep diving or entering piston shoe is utilized and swingably borne in the pivot-bed of the radially reciprocating piston.  Since deep diving piston shoes have large piston strokes, the shoes pivot in the pistons in large angles.          Thereby a considerable force portion of the load on the piston is transferred to the wall between the piston and the cylinder, whereby heretofore short pistons produced occasional   welding and sticking between the cylinder wall and the piston wall.  The piston therefore receives radially extending portions, which may extend beyond the medial portions of the piston shoe and may even enter into the ring groove of the piston stroke actuator ring.  Thereby a very long guidance of the piston on cylinder wall portions is obtained, which makes the application of effective pressure balancing pockets at correct location between piston wall and cylinder wall possible.  An extended piston guide and friction - less travel of the piston in the cylinder without wearing or sticking is assured.

Abstract: DIGITAL CONFERENCE CIRCUIT AND METHOD Abstract of the Disclosure A digital conference circuit for a digital telephone switching network is provided, connected between a receive TDM (time division multiplex) bus carrying PCM (pulse code modulation) words to the conference circuit and a transmit TDM bus carrying PCM words from the conference circuit.  A memory (storage) device stores the PCM words most recently received on the receive TDM bus and decision circuitry determines, for each conferee, which two PCM words, excluding the PCM word originating from that conferee, should be read from the memory device. The two PCM words so read are attenuated in a predetermined fashion, summed, and the resultant PCM sum applied to the transmit TDM bus during an appropriate timeslot.  The decision circuit makes its decision based upon the largest average magnitude of each conferee's PCM words, received at the conference circuit, during the previous frames.  In other words, for transmission on the transmit TDM bus to a given conferee, two PCM words are chosen from amongst the other conferees based upon the largest average magnitude of those conferee's PCM words.

Abstract: ABSTRACT OF THE INVENTION            One or more electrodes of an electro-optic device are supported on a separate substrate which is held in close contact with the electro-optic element of the device so that the electric fields that are created when voltages are applied to such electrodes are proximity coupled into the electro-optic element.  Proximity coupling is especially advantageous for multi-gate light valves and the like where separate electrical connections have to be made to a multitude of electrodes because it permits those connections to be made remotely from the electro-optic element.  However, the broader aspects of proximity coupling are applicable to electro-optic devices in general, including bulk and TIR electro-optic modulators and straight through and TIR multi-gate electro-optic light valves.

Abstract: Abstract The invention comprises a carburetion apparatus for use with an internal combustion engine having a generally conventional carburetor, an intake manifold and an exhaust manifold.  The carburetion apparatus has a central chamber that receives the fuel-air mixture from the carburetor and delivers the fuel-air mixture to the intake manifold.    The central chamber is provided with baffles to divert the fluid flow and cause intimate mixing of fuel and air.    The baffles are such that the manifold vacuum is raised (or, the pressure is lowered), so the vacuum assists in evaporating liquid fuel.  The baffles may be heated by passing exhaust gases through them, the exit of the exhaust gas being slowed by a constricted outlet.

Other encoders are positioned, respectively, on a wheel of the support towers of both the end section and the next adjacent section of the center pivot boom to determine the angle between a reference line and a straight line connecting the center pivot point and the end of the center pivot boom.  From this information, the location of the end of the corner boom can be precisely determined, so that the electrical signals which control is movement can be generated and supplied to the corner boom at the proper time to result in the desired movement of the corner boom.
