Title: Electrical connector with grounded rotating collars
Inventor: REES DAVID G
IPC: H01R13/648
Filed: 1987-09-08
Granted: 1991-03-05
Abstract: ABSTRACT     An electrical connector of the plug and socket type having an independently grounded rotatable collar which is connectable to a ground line potential prior to connection of the live electrical load.  The grounding mechanism includes a generally U-shaped spring contact which is compressed on interconnection and which is continually forced into electrical contact with a peripherally surrounding surface of a mating collar.  The spring tendency to outwardly expand so as to maintain contact is enhanced by generally triangular radially extending tips of the body of the connector which are also compressed on interconnection and which bias the spring contact radially outward.

Granted: 1991-12-10
Abstract: "QAM Demodulator With Rapid Resynchronization Function"                            ABSTRACT         In order to rapidly resynchronize a QAM demodulator by effectively operating a transversal equalizer, a message point of an incoming quadrature-modulated signal is checked as to its location within a signal space diagram.  In the event that the message point is deviated within a predetermined region of the signal space diagram, a transversal filter functions normally irrespective of whether or not a demodulating section is synchronized, while in the event that the message point is deviated outside the predetermined region, the transversal filter is allowed to perform the normal operation-thereof only if the demodulating section is in synchronism.

A resistive material is next printed to portions of the resistor terminations and to the dielectric substrate intermediate the resistor terminations.  The resistive material is fixed by drying and firing in air.          Terminal pads, conductor traces and resistor interconnections are printed on the dielectric substrate using a base conductor material.  The resistor interconnections are also printed to the resistor terminations and to portions of the resistive material.  The terminal pads, conductor traces and resistor interconnections are then air dried and fired in nitrogen.  The resistor material is trimmed to tolerance by kerfing the resistor material and a dielectric encapsulant is printed substantially over the resistor interconnections and resistive material.          The encapsulant is cured using an infrared light source, or conventional oven.

Abstract: PRIORITY FLOW CONTROL VALVE     ABSTRACT OF THE DISCLOSURE         An automatic switching valve mounted between two fluctuating pressure sources automatically switches from one source to the other to supply gas or liquid from the source that is under the higher pressure.  A T- hous-ing conveys gas or liquid from either side and out of the central stem.  Tapered, spring loaded plugs or valves in either side engage with tapered seats and are maintained in contact with the seats by springs which permit one or the other valve to open when the pressure on one valve exceeds the tension of the spring of the other valve.  If the pressure is equal on both sides, both valves will open simultaneously if pressure is greater than cracking pressure.

Abstract: ABSTRACT The method of well construction includes the steps of drilling the rock and consolidating it with a con-ductor casing, a surface casing string and a flow string, and isolating the troublesome zones of the well with profile pipes being reamed in the course of their setting. The reaming of the profile pipes is effected by building up a pressure drop across them and subsequently expan-ding them. The drilling of the rock after the casing-in of the well with the conductor casing and the surface casing string 19 performed with a bit of one and the same diameter, with the troublesome zones being reamed to a diameter equalling the outer diameter of the reamed profile pipes which are successively set in all the troublesome zones as they are exposed by the drilling.

Abstract: INVENTOR      IZAK BAHAR TITLE OF THE INVENTION      POSITIVE STEP IMMUNOASSAY ABSTRACT OF THE DISCLOSURE      An assay procedure that is particularly valuable for detecting and/or determining the presence of threshold levels of analyte ligands in biological fluids.  In one particularized and specialized aspect the disclosure is directed to procedures for detecting and/or determining threshold levels of hormone metabolites such as pregnanediol-3-glucuronide (P3G) and estrone-3-glucuronide (E13G) in human urine.  The assay consists of contacting a sample containing the analyte with a known amount of an antibody thereto and with a calibrated amount of the analyte itself that is conjugated to said solid support.  When the level of the analyte in the sample exceeds a threshold level, such as 5 ug/ml for P3G, the antibody will be insufficient to block all of the corresponding analyte on the solid support.  Thus, upon addition of labelled antibody to the assay system, a detectable immunoreaction product becomes attached to the support to indicate that the amount of analyte in the sample exceeds the threshold level.  On the other hand, if the level of the analyte in the sample is below the thres-hold amount, the free antibody will be sufficient to block all of the corresponding analyte on the solid support preventing labelled antibody from forming a detectable immunoreaction product on the support and thus no signal will appear.
