Abstract: ABSTRACT OF THE DISCLOSURE           The subject invention concerns novel compositions for use in immunoassays, as well as immunoassays employing such novel compositions.  The compositions comprise discrete charged colloidal particles comprises of small molecules which particles are capable of retaining their discrete character in an aqueous medium and composed of aggregates of lipophilic and/or amphiphilic organic molecules to which are bound non-covalently a label capable of producing a detect-ible signal and a ligand or an analog of the lignad capable of competing with a ligand for a ligand receptor.  The discrete colloidal particle serves as a hub or nucleus for retaining the ligand or its analog and the label within a limited locus.  The compositions are prepared by individ-ually covalently bonding the ligand and the label, when not naturally lipophilic, to a lipophilic (includes amphiphilic) compound, normally a phospholipid.  Depending upon the nature of the particle, the amphiphilic conjugated ligand and label are combined with the particle or alternatively may be combined with the compounds employed for preparing the particle under particle forming conditions. Particles are then obtained having the analog of the ligand and the label bound to the particle.  The compositions find use in immunoassays where an interaction between the label and receptor provides a means for modulating a detectible signal.  The interaction can be as a result of quenching or modification of fluorescence, where the label is a fluo-rescer, steric inhibition of the approach of a signal modifier to the label, such as a label receptor or with an enzyme label, an antienzyme or enzyme inhibitor, the in-hibition of cleavage of an enzyme labile bond or the co-operative interaction of two labels, such as two enzymes, where the product of one enzyme is a substrate of another enzyme.

Abstract: Abstract Of The Disclosure For convenience in handling, etc., use is made of a concrete or similarly fabricated member which, although actually a single rectangular block-like member, has a surface line impression effectively simulating a selected arrangement of plural individual pavers or bricks, thereby giving the desirable impression that the construction is formed by said individual bricks, rather than by the fewer number of construction blocks.          In accordance with the present invention, the  line-forming means, which simulates the individual bricks, is retracted from its position impressed into the concrete mass or mixture through slots in a press-plate having wiping surfaces which removes any adhering concrete therefrom, and thus the shaping contour of said line-forming means is properly preserved for succeeding brick-simulating service.  The term "brick" as used herein is intended to broadly encompass regular as well as irregular shapes, such as stones.

Abstract: "SLUG AND WIPE TOOL" ABSTRACT OF THE DISCLOSURE           When pipe is being pulled, there is considerable difficulty experienced in removing the drilling mud from the pipe sections and this mud often spills upon the drilling floor as the pipe lengths are raised and disconnected because the mud in the drill pipe cannot escape through the circular holes in the drill bit fast enough to eliminate this spillage.  In the present device a cylindrical slug is used having one or more wipe rings thereon. This is placed down the drill string and applies weight to the column of drilling mud within the drill string and forces it out through the drill holes.  It is situated at a predetermined distance down the drill string de-pending upon the weight of the slug and includes one or more wiper rings which clean the bore of the drill string as the drill string is raised.  A replaceable rupture disc is provided in case the device becomes jammed or mud circulation has to be restarted so that the tool does not interfere with the normal operation of the drill if it remains in the pipe.  Means are provided engageable by an overshot on a wire line if it is de-sired to fish for the tool in order to remove same prior to removing the entire drill string from the drill hole.

Abstract: Abstract of the Disclosure The optical nonreciprocal device is used to optically couple together two opposed optical fibers.  The light from one optical fiber is separated into ordinary ray and extra-ordinary ray by a first birefringent crystal member.  The separated ordinary and extraordinary rays are subject to a total of 90° polarization rotation by transmitting in a forward direction through a magneto-optical member having an angle of polarization rotation of 45° and through a compensating plate.  The separated ordinary and extraordinary rays are synthesized by transmitting through a second bire-fringent crystal member and then applied to the other optical fiber.  A lens is interposed between one optical fiber and the first birefringent crystal member for causing the light to propagate through the light path while being converged or diverged.  By suitably selecting the thick-nesses of the first and second birefringent crystal members, the ordinary and extraordinary rays propagating from the second optical fiber to the first optical fiber in the reverse direction are prevented from being overlapped at the incident end of the first optical  fiber thus providing an optical isolator.

Abstract: ABSTRACT         A facsimile recorder having the capacity to record signals at different sweep rates and a circuit to distinguish noise from synchroniza-tion pulses so that the correct sweep rate will be utilized.  The circuit includes a grounded timer switch which receives a start signal and opens to the voltage of the circuit and another switch which is opened to ground during the period between each of the phasing pulses.  Two capacitors are arranged in parallel to receive a charge simultaneously while the switch is opened but a diode between them allows discharge of only the first of them when there is an interruption due to either noise or the next synchroniza-tion pulse.  Since the rate of charge on the capacitors is substantially linear with respect to time, the charge on the second capacitor will remain at the highest level seen between the end of one pulse and a burst of noise or the next pulse if there is no noise.  The voltage of the second capacitor is displayed to level detectors which signal a logic circuit in the recording equipment to direct the sweep rate of the recorder.

Abstract: ABSTRACT OF THE DISCLOSURE     An electromagnetic discharge apparatus has a power coupling fixture which couples power to both ends of an electrodeless discharge vessel and produces a substantially uniform arc.  Power can be coupled to the fixture from two high frequency power sources or can be coupled from a single high frequency power source by using a power divider.  If power is coupled to the electrode-less discharge vessel from a single source, power trans-fer to the vessel is optimized when the electrical length of the circuit is an integral number of wavelengths.  In an alternative embodiment, a second coupler is utilized in a conventional electrodeless light source to shape the electric fields and produce a more uniform arc.
