Abstract: ABSTRACT OF THE DISCLOSURE   Casing inspection apparatus and method are disclosed for determining defects and other anomalies in ferromagnetic oil well casing.  The inspection apparatus utilizes a pair of coaxial transmitter coils for generating an alternating magnetic field in the casing thereby including circumferential currents in the casing wall.  These circumferential currents and the magnetic field associated with the currents are perturbed by corrosion, holes, and other anomalies both inside and outside the casing wall.  Differential receiver coils are urged in proximity with the casing wall to generate a differential receiver signal in response to such perturbations in the magnetic field.  The differential receivers are provided with three coils serially connected and having N, 2N and N winding turns respectively.  The windings of the coils are disposed in adjacent relationship to one another and wound in a direction opposite to the adjacent winding.  The casing inspection apparatus achieves enhanced sensitivity to small defects and reduced sensitivity to magnetic anomalies by processing both the amplitude and phase components of the receiver signal.

Abstract: Abstract of the Disclosure A channel selector system in a radio for sequentially selecting one of a plurality of channels and rapidly scanning through any restricted channels such that the restricted channels are not displayed and appear to be skipped.  The radio includes a frequency synthesizer for generating a predetermined frequency associated with each selected channel and the channel selector system has a sig-nal generator which causes the frequency synthesizer to sequentially either step or scan through the channels including some channels which may be restricted.  The gener-ator provides an output coded signal to indicate selection of a restricted channel which is decoded by decoding circui-try.  A scan timer is responsive to the decoded signal to cause the signal generator to rapidly scan through re-stricted channels.  A latching circuit latches a signal generator input during rapid scanning through restricted channels until the system advances to the next unrestricted channel.  Related methods are disclosed.

Abstract: An electronically tunable oscillator comprises a transistor coupled to ground by an emitter resistor. In the circuit, the collector and base of the transistor are connected in series with an inductor.  The inductor is connected by a tap to a bypass capacitor and a B+ voltage source.  The source maintains the collector and base at the same DC potential.  The collector of the transistor is coupled to a capacitance which cooperate  with the inductor to provide a tuned circuit.  At least part of the capacitance is provided by a varactor whose value can be controlled to determine oscillator frequency.  The magnitude of the oscillator frequency is limited to two times the base to emitter voltage of the transistor and the use of the emitter resistor cooperates to minimize distortion.

Abstract: Abstract of the Disclosure The present invention is directed to improvements in non-toxic polyurethane compositions and separatory devices employing the same, such as hollow fiber separatory devices intended to be used in biomedical applications.  The separatory device employs at least one separatory membrane suitable for the intended end use application which is secured, potted or sealed in a housing using a cured flexible polyurethane composition.  The improvement in the polyurethane composition employed in the separatory device is achieved by reacting at least one NCO-terminated prepolymer and at least one polyol in the presence of a ricinoleic acid reactive catalyst.  The catalyst reduces the curing time of the polyurethane resin and because it is sufficiently reactive with the NCO-terminated prepolymer, it is incorporated into the structure of the polyurethane and cannot be released during operation of the separatory device.

Abstract: Abstract of the Disclosure _ _   ...    . _ Curved last soles for athletic shoes are disclosed, including one embodiment wherein cleats are arranged with grip-ping edges in the arch and heel that are perpendicular to the longitudinal axis passing therethrough, whereas in the toe cleats are arranged with gripping edges that are aligned in rows that are perpendicular to a line generally defining the direction of travel while the athlete abducts his or her feet during the propulsion phase of running.  Cleats in the ball portion of the sole fan out to provide a smooth transition from the cleats in the arch to the cleats in the toe.         In a second embodiment the cleats are disposed throughout the sole in rows which maintain a perpendicular relationship relative to the longitudinal axis of the heel, but the orientation of the gripping edges of the cleats in the toe and ball portions are varied in such manner as to com-pensate for the aforementioned abducting effect.  Cleats of two different heights are provided, relatively tall ones in the ball, relatively short ones in the toe and arch and both heights in the heel.         In a third embodiment especially intended for racing, the cleats are closely spaced between curved-bottom grooves in a very lightweight sole of expanded synthetic rubber.  The cleats are aligned in bar-like rows which are oriented to com-pensate for the aforementioned abducting effect.

Abstract: FIBER OPTIC CONNECTOR       ABSTRACT The present invention relates to a fiber optic connector, and more particularly, to the fastening system employed to couple the connector to a fiber optic cable. Fiber optic cables typically include a transparent fiber encased in an insulation sleeve, a giber sleeve and an outer shell.  Prior art connectors are deficient in that the outer shell is not securely attached to the connector, thereby increasing the potential for damage to the transparent fiber.  The present invention provides a con-nector with a cable insertion member having first and second annular portions, the first portion having a larger outside diameter than the second portion.  A ferrule mechanically stabilizes the cable to the connector and sandwiches the sleeves to the first portion and the sleeves and the shell to the second portion.  The cable, including its shell, is securely coupled to the connector.

Abstract: ABSTRACT A water softener control includes a cell (29) of sampling resin (30) which received periodic samples of water which has passed through a major portion of the softening bed (11).  The sampling resin (30) changes volume when it becomes exhausted and the change in vol-ume is employed to initiate regeneration of the soften-ing bed (11).  At the start of the regeneration cycle, regenerative fluid is delivered directly to the sampling resin (30) as well as to the softening bed (11).  The delivery to the sampling resin (30) is through a control valve (60, 70) which is piloted by pressures at a venturi injector (21) which is used to withdraw regenerative fluid from a brine tank (22).  A vacuum operated control valve (75) which is responsive to the closing of an air check valve (25) in the connection between the injector (21) and the brine tank (22) may be employed to positively close the connection from the sampling cell (29) to the injector (21) when the supply of regenerative fluid is exhausted.
