Abstract: A METHOD FOR CARRYING OUT NON-ISOTOPIC IMMUNOASSAYS, LABELED ANALYTES AND KITS FOR USE IN SUCH ASSAYS ABSTRACT A highly sensitive, immunoassay method for determining the amount of an analyte in a sample containing a known analyte in an unknown concentration is provided. Sample; a polypeptide-labeled analog of the analyte, an antibody specific for said analyte, a polypeptide partner capable of non-covalently binding with the polypeptide-labeled analyte to form a complex having catalytic activity, and a substrate capable of being converted to a reporter molecule by the catalytic activity of said complex are brought together in a medium. The polypeptide-labeled analyte analog is capable of competitively binding to the antibody and the polypeptide partner, the antibody inhi-biting the formation of a catalytically active complex in the absence of analyte, and the concentrations of the antibody, polypeptide partner and polypeptide-labeled analyte are such as to cause varying amounts of analyte to be directly related to the conversion of the substrate to the reporter molecule. Conversion of the substrate to the reporter molecule is then determined, and compared to conversions of substrate to reporter molecule obtained with known concentrations of the analyte.

Abstract: A B S T R A C T     A hydrodynamic, non-contacting end-face seal for a rotary machine comprises a rotor mounted on the machine shaft and a ring-shaped stator facing the flat and smooth surface of the rotor at a short distance.  The stator encloses the machine shaft, is eccentrically positioned in respect of the rotor center, and is urged towards the rotor surface by a helical spring.  The surface of the stator ring is shaped to form a circular rim separated from the rotor surface by a very small gap of varying width, and the space enclosed by this rim is raised to a higher pressure than the surroundings by the hydrodynamic action of the surface velocity of the rotor on the liquid in the machine, by making the gap width as follows:-the gap width between rotor and stator is of a mechanically per-missible minimum in all points of therein at which the velocity vector of the rotor surface extends from the inside of the rim to the outside, and the gap width is larger in all points of the rim at which the velocity vector extends from the outside to the inside.          The gap width is changed, in accordance with pressure conditions in the machine by action of the helical spring.

Abstract: ABSTRACT OF DISCLOSURE            Disclosed is an improved sucker rod packing gland for oil well pumps.  The improved packing gland has two packing sections, a lower section and an upper section with a reservoir disposed between them.  Oil which leaks through the lower packing section is contained in the reservoir between upper packing section and drained from the reservoir by a return line which delivers it back to the well.          Delivery of the oil collected in the reservoir through the return line is accomplished by a pressure differential built up in the reservoir by reason of the two packing stages and the gravity flow continues on the return line.

Abstract: ABSTRACT          A thermal head device for use in a facsimile machine and the like as an output device is provided.  The thermal head device comprises a plurality of heat-producing electrically resistive elements formed on an insulating substrate arranged in a single line to form a thermal array.      A plurality of tape carriers, each comprised of an insulating film strip and conductive paths formed thereon in a desired pattern, are used to provide interconnections between the resistive elements and external circuits.  An image informa-tion signal is applied to the resistive elements through the tape carriers thereby the resistive elements are selectively activated to produce heat in accordance with the signal supplied.  Therefore, a visual image may be obtained by advancing a thermosensitive paper in contact with the thermal array in the direction perpendicularly thereto.          The present invention provides numerous improvements in such a thermal head device.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and a method for compacting articles made of powder material at a constant density, or at  a density within a range.  An example of apparatus for practicing the method of the invention takes the form of a hydraulic piston-cylinder assembly, defining a chamber which is filled with an incompressible hydraulic fluid, disposed in the coupling between the actuating member of a mechanical press ram and the ram.  The hydraulic fluid is pressurized by a compressed compres-sible fluid, such as air, acting on a large area piston directly coupled to a small area piston disposed in a small diameter cylinder filled with the incompressible hydraulic fluid and in communication with the chamber, the ratio in the areas of the pistons determining the pressure amplification rate or gain.  When the press ram meets a resistance to its travel which is large enough to overcome the pressure of the hydraulic fluid in the chamber, the volume of the chamber is decreased with the result that hydraulic fluid is introduced in the small diameter cylinder, thus displacing the small area and the large area pistons against the pressure of the compres-sible fluid, cushioning  the impacts and shocks to which the ram is subjected in operation, and effecting compaction at constant pressure, or at a pressure within a range.

Abstract: Abstract A reusable laboratory filter unit having a recoverable filter member.  The unit has an upper body or reservoir for receiving the liquid to be filtered and a lower body or receptacle for receiving filtrate.  A plate for supporting the filter membrane is captured between the upper and lower bodies when the bodies are joined together.  A threaded ring arrangement draws the bodies together axially without rotating one with respect to the other so the membrane is not subjected to any twisting force.  Separation of the bodies exposes the support plate so it can be easily removed to recover the membrane.

The gas containing zinc vapour is brought into intimate contact with atomized lead in liquid form which takes up the zinc.  The lead is introduced at the top of a cooling tower (1) and the gas is conducted in counter-flow to the atomized lead droplets.  Lead collected at the bottom of the tower (1) is transported (7) to a separating chamber (8) where it is cooled, so that the zinc is segregated from the lead and can be separated (10).  The lead is then cooled further before being recirculated (15, 16) to the top of the cooling tower.
