Abstract: ABSTRACT         In a tracking system for radio beacons using genera-tion of TE21 mode components in a circular waveguide to detect misalignment, correct antenna alignment is achieved even where the signal from the beacon is linearly polarized by extracting TE21 mode signals from the waveguide through longitudinal pairs of slots in planes at an angle .pi./4 to one another, phase detec-ting the difference signals from said pairs of slots to provide signals for aligning the antenna on two orthogonal axes, and in the case of linear polarization rotating the slots about the waveguide axis so as to correspond with the rotation required of a 180° polarizer receiving the waveguide signal through a 90° polarizer so as to provide a predetermined polarization of the output signal.

Abstract: Abstract of the Disclosure Sterilization of the surfaces of objects is achieved by placing the same in a continuous flow of a low temperature, low pressure gas plasma, containing small amounts of aromatic, heterocyclic, saturated or unsaturated aldehydes alone or mixtures thereof.  The gas plasma is a partially ionized gas composed of ions, electrons and neutral species, which may be formed by electromagnetic discharges at subatmospheric pressure in the 1 to 300,000 Megahertz range, and corresponds to a minimum average spatial energy density of 0.001 watts per cubic centimeter.  The gas plasma may also contain other vaporized cidal agents.  Contrary to most gaseous steriliza-tion procedures, the method is safe, allows quick handling of heat sensitive items, does not corrode equipment and does not leave toxic residues.

Abstract: ABSTRACT         An exhaust gas oxygen sensor and electrical connector arrangement for use in connecting the sensor to an electronic device capable of utilizing an electrical signal produced by the sensor.  The electrical connector arrangement eliminates both male and female electrical connectors required in prior sensor electrical connector arrangements. The new electrical connector arrangement provides a leak-proof connection between a cylindrically-shaped sensor member and a connector assembly including an elastomeric grommet, a plastic sleeve and a plastic spacer used to retain connector terminals within the sleeve for receipt of cooperating terminals on the exhaust gas sensor.  The connector-assembly sleeve and the cylindrically-shaped member of the oxygen sensor cooperate to produce a positive latching action of the connector assembly to the exhaust gas sensor.

Abstract: ABSTRACT      A film-forming polymerizable resin is produced from combining acrylic acid, the diglycidyl ether of N-butyl diol and 3,3',4,4'-benzophenone tetracarboxylic dianhydride (BTDA).  The diglycidyl ether of N-butyl diol is combined with BTDA and sufficient acrylic acid to combine with unreacted epoxide groups.  The BTDA constitutes 2 to 10 percent by weight of the three ingredients.  The ingredients are heated to a low acid number where the epoxy equivalent of the mixture is greater than 3500.  The resulting film-forming resin can be pigmented and can be cured in the presence of ultraviolet radiation.

Abstract: ABSTRACT OF THE DISCLOSURE The encrypter of the encrypting and decrypting system samples the incoming analog signal at a constant period and delivers an encrypted signal by successive reading of the samples under the control of an encrypting signal which has a predetermined period multiple of the sampling period, The decrypter of the system performs the inverse function to reconstruct a de-crypted signal analogous to the incoming signal.     The encrypter and decrypter each comprises two delay lines, In the encrypter, the incoming signal is sampled and written at the sampling period during each of predetermined periods so as to fill all the stages of a delay line. Then the samples are read according the initial order at the instants of a time distribution which is predetermined by the encrypting signal and which is different from the time equidistributed writing instants. The analog encrypted signal results from at least time compressions and eventually time expansions of the incoming signal samples.
