Abstract: METHOD OF DETECTING A SPECIFIC MICROORGANISM ABSTRACT OF THE DISCLOSURE A method of detecting a specific microorganism compris-ing contacting said microorganism with bacteriocins from a microorganism of a genus which is taxonomically unrelated to said specific organism. The result of such contact may be utilized to detect the presence of a micro-organism belonging to a taxonomically unrelated genus. Radio-labeled or fluorescein-labeled bacteriocins can be reacted with specific bacteria in a biological sample and the presence of such specific bacteria detected by remov-ing excess bacteriocins and determining the presence of fluorescent or radioactive bacteria in the sample. Neisseria gonorrhoeae is identified by spotting bacterio-cins on a plate of clinical material; or using a disk impregnated with bacteriocins placed on a plate inoculated with the clinical material; or the bacteriocins can be incorporated into one-half of a split agar plate, the identification being made on the basis of a zone of inhibition surrounding the spot where the bacteriocins were applied, or growth inhibition on the portion of the plate to which the bacteriocins were added.

Abstract: Abstract Spring expansion systems associated with rigid axles have been employed on a wide variety of vehicles, but some problems are inherent in such systems because of the nature and configuration of the various springs employed. This invention solves the problems providing structure to prevent fore and aft movement of the ends of the axle relative to the vehicle, and constrains the axle to move vertically without significant lateral motion.  Trailing radius arms connected to respective sides of the axle and frame prevent the forward and aft movement of the axle, and symmetrically mounted track bars constrain the lateral motion of the axle relative to the vehicle.

Abstract: DIELECTRIC WELL LOGGING SYSTEM AND METHOD                 (D#74,724-1-F) ABSTRACT OF THE DISCLOSURE         A dielectric well logging system includes a logging tool adapted to be passed through a borehole traver-sing an earth formation.  The logging tool includes a transmitter which induces electric energy into the earth formation at a radio frequency.  Two receivers in the logging tool spaced a predetermined distance apart provides intermediate frequency signals corresponding to the elec-trical energy received from the earth formation.  The inter-mediate frequency signals are transmitted by way of a cable to the surface.  Surface electronics include zero crossing detectors, each detector receives a different intermediate frequency signal from the cable and provides a detector signal whose change in amplitude is representative of the intermediate frequency signal passing through zero.  A source provides clock pulses at a frequency substantially greater than the frequency of the intermediate frequency signals.  A logic circuit receiving the detector signals and the clock pulses provides groups of clock pulses in accordance with the detector signals.  The number of clock pulses in each group corresponds to the dielectric constant of the earth formation.                             I

Abstract: DYNAMIC SKEW CORRECTION FOR ROTATING HEAD MAGNETIC RECORDER Abstract of the Disclosure Parallelism between the track on magnetic tape and the path of the rotating head is dynamically adjusted and maintained by adjusting one or both of the entry or exit guides guiding the tape as it helically wraps a mandrel.  The mandrel has two halves that flank the rotating head so that as the tape wraps the mandrel, the rotating head traverses the tape at an oblique angle.  Skew error is represented by a lack of parallelism between the track on the tape and the path of the rotating head across the tape.  The skew error may be corrected by laterally shifting either the entry or exit tape edge guide without distorting the track over a limited lateral range of movement by the guides.  The entry and exit edge guides are continuous-compliant air-bearing guides.  Similarly, the mandrel that supports the tape adjacent the rotating head is also air bearing.

Abstract: Abstract Individual items of personalized jewelry can be made with the name of the wearer or other personal message set forth in prominently embossed or deeply sunken letters on the jewelry item without expensive tools, dies, molds or fixtures, and preferably in conjunction with the lost wax process.  A name or other alpha-numeric message, can be prepared, for example, with a typewriter.  Special designs, such as a family coat of arms or an organization symbol, can also be prepared for use with a name or other message.   The name, message and design can be produced in either sunken or embossed letters by photo-etching the name or message onto a substrate bearing a photopolymerizable resin.          The photopolymerizable resin bearing the name, message and design can be used to form wax patterns bearing the name, message and design by casting from the resin a master die insert bearing the name, message and design for preparation of the wax pattern.  Using the lost wax process, the wax pattern is then used to prepare a mold in which the jewelry item will be cast.

Abstract: CONTROLLABLE RECTIFIER CIRCUIT FOR A POWER SUPPLY     ABSTRACT OF THE DISCLOSURE            A controllable rectifier circuit which may be used in a power supply selectively produces a half-wave or a full-wave recti-fied signal.  The rectifier circuit includes a pair of input termi-nals for receiving an AC signal and a bridge rectifier coupled to the input terminals and including a pair of output terminals across which a rectified AC signal is produced.  The bridge rectifier com-prises a first current path including a switchable rectifier for conducting positive half cycles of the AC signal and a second current path including a switchable rectifier for conducting negative half cycles of the AC signal. A pulse generator is supplied with reduced amplitude versions of the positive and negative half cycles of the AC signal, in sequence, to produce an output pulse when the reduced amplitude of the half cycle supplied thereto is less than a predeter-mined level.  A non-reduced half cycle of the AC signal is selectively supplied to the pulse generator to present the pulse generator from generating an output pulse during that half cycle so that an output pulse is generated only during the beginning and ending portions of the other half cycle.  The generated output pulses are supplied to each of the switchable rectifiers, whereby the bridge rectifier rectifies both half cycles of the AC signal when the non-reduced half cycle is not supplied to the pulse generator, and the bridge rectifier rectifies only the other half cycle of the AC signal when the non-reduced half cycle is supplied to the pulse generator.                             -i-
