Abstract: ABSTRACT           The present invention presents a method and apparatus for stabilizing signals in radioactive well logging tools in-cluding providing in the tool a main scintillating crystal and photomultiplier tube for detecting radiation induced in the borehole by a source of radiation, and a reference crystal, in-cluding a source of mono-energetic radiation, for producing continuous reference signals of a predetermined energy level.     The reference signals are monitored and the spectrum is stab-ilized to correct for drift of the data signals introduced by the photomultiplier tube and the data transmission system.  The pre-ferred mono-energetic reference signals are selected to appear in the energy spectrum at a level which minimizes error.  An electronic circuit at the surface provides a correction signal for adjusting the gain of a data signal amplifier responsive to changes in the reference signal, thereby correcting for drift in the data signal.

Abstract: ROTATABLE SHAFT COUPLING Two coaxial shafts having respective adjacent ends are joined together by a coupling assembly including a coupling sleeve which is rotatably supported within the interior of a third shaft concentrically disposed about the coaxial shafts.  The adjacent ends of the coaxial shafts have external splines which are configured to be inserted into and engage internal splines formed in the bore of the coupling sleeve.  The third shaft is rotatably supported by a housing in which the coupling assembly is positioned and may include an output sleeve portion.  The coupling assembly is advantageously employed in the drive train of heavy vehicles in which the coaxial shafts form a part of the transmission input shaft and the third shaft forms a part of the transmission output shaft.

Abstract: POLYETHER POLYOLS AND METHOD OF PREPARING SAME     Abstract of the Disclosure New polyether polyols of predetermined structure are prepared by reacting polyether bis alcoholates with selected bis epoxides.  Specifically, a polyoxyalkylene glycol is converted to the bis alcoholate, and then the bis alcoholate is reacted with an equivalent amount of a glycol bis glycidyl ether, with the reactants being mixed together all at once.  The polyether polyalcoholate thus obtained is converted to a high molecular weight polyether polyol by acid neutralization or ion exchange.

Abstract: A ROTOR FOR A ROTARY ELECTRIC MACHINE          ABSTRACT OF THE DISCLOSURE         A rotor structure draws surrounding air into chambers formed by adjacent pairs of spider arms through air inlet holes in cover plates enclosing the spider arms, due to the fan action of the spider arms upon rotation of the rotor.  The air in the chambers then flows into the stator after cooling an annual yoke and windings.  During this period, the high temperature portion of the machine is cooled by this.          According to the ventilation structure of the present invention, the air inlet holes in the cover plates are out of alignment with each other so that air currents passing through them do not collide with each other, thus reducing windage loss and increasing cooling efficiency.

Abstract: (Case No. 6863) BROKEN RAIL DETECTING TRACK CIRCUITS                 ABSTRACT OF THE DISCLOSURE    Two sensor coils are positioned one adjacent each separate gage rail at the track relay end of a dual gage track section in which train detection current flows in the two gage, i. e., other than common, rails in parallel and returns through the common rail to the energy source.  The signal induced in each sensor coil by this track circuit current is applied to a separate receiver broadly tuned to the track circuit frequency.  The amplified receiver outputs are applied to a comparator unit which generates an output signal only when the inputs from the receivers are substantially equal as a result of equal other rail currents.  The comparator output holds energized a broken rail detector relay which releases to indicate a broken rail condition in the other rails when the sensor coil signals differ by a predetermined amount.  If possibility of a shunt fault between the other rails exists, the detector arrangement is supplemented by an audio frequency (AF) circuit in the loop formed by the two other rails in parallel.  The comparator detects broken rails if a shunt is close to the coils while the AF detector functions to detect broken rails when a shunt is further from the coils.

Well is first logged with gamma ray detection system to provide a base log.  Fluid contain-ing salt of potassium, uranium or thorium is then injected into the well opposite the interval of interest.  When the well head pressure is increased, some of the injected fluid will move into the channel which is allowing fluid to move between different zones in the formations around the well.  The gamma ray detection system is then again run through the well to provide a log which is compared with the base log.  The channel between zones is detected by localized drastically higher readings observed on the repeat run of the gamma ray detection logging system.     -1a-

Abstract: Abstract of the Disclosure It is known to apply liquid crystal solutions to a substrate, dry the coating and then cover the coated substrate with a further protective coating.  Such coated substrates lack sufficient adhesion between the various coatings to be useful.  Additionally it is difficult to coat substrates with liquid crystals.  The present seeks to provide a pulverulent liquid crystal composition useful in preparing coating composition.  The present invention provides a process for preparing a pulverulent micro-encapsulated cholesteryl-type liquid crystal composition comprising mixing about equal parts of a micro-encapsulated cholesteryl-type liquid crystal having a particle size from about 10 to about 30 microns with a binder from the group comprising:  (a) an animal protein composition comprising from about 10 to about 20% protein, up to about 0.8% phosphate and the balance water; (b) a cellulosic composition comprising from about 10 to about 20% cellulose or a derivative thereof, and the balance solvent; (c) a milled polyester having a particle size of from about 10 to about 30 microns; and where the resulting mixture is a slurry, spraying the slurry into a vessel heated at a temperature up to 70°C and evaporating the solvent from the slurry, to form a film inside said vessel, removing said film from said vessel and mechanically crushing the so removed film to a particle size of less than 20 microns.

The push-off units of the plural stations are activated sequentially, in correspondence to the sequence in which glass gobs are fed into the respective machine stations.  Plural electric motors are provided, one per station, and the swing motion of the push-off unit is generated by the respective electric motor.  The rotation of each electric motor is controllable, by open- or closed-loop control, indepen-dently of the other electric motors.  The operator selects the sequence in which the electric motors are to be activated.  A common or shared desired-rpm voltage is applied to all electric motors, sequentially.
