Title: Leak resistant diaper or incontinent garment
Inventor: LANCASTER EUGENE P
IPC: A61F13/494
Filed: 1985-02-20
Granted: 1988-05-03
Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a leak resistant disposable diaper or incontinent brief particularly suitable for adult wear. The garment is from about two to three times as long as it is wide so that the sides of the wearer are not covered. Each end of the garment has a relatively long nap formed by extensions of the envelope retaining the pad of absorbent material. The absorbent pad itself is trimmed generally in the form of an hourglass. However, the cutout side portions are located forward of the transverse centerline of the pad. Also, the forward edge of the cutouts does not expand as rapidly to full width as does the back edge to allow a better fit in the groin area. Elastic strips are located adjacent to the edges of the pad and run the full length of the product. Relatively long attachment straps are anchored to the back flap and form the means of holding the garment on the wearer. The adhesive on the free ends of the attachment straps is preferably one that is high in shear strength but low in peel strength in reference to the thermoplastic moisture impervious backsheet of the diaper. This allows the straps to be easily removed and reattached if desired, but provides n firm grip while the garment is being worn.

Abstract: ABSTRACT OF THE DISCLOSURE.      The present invention relates to a method for obtaining a tenacious in-situ coating deposition of calcite on the inner surface of water pipes at very high rates.  The calcite producing ingredients are supplied to the water stream in quantities supplementing concentrations available in the natural water used, giving the required supersaturation levels by addition of suitable salts to provide an aqueous lining solution supersaturated with respect to calcium carbonate containing dissolved calcium and carbonate ions.  The method consists in maintaining the suspended calcium carbonate particles concentrations in the lining solution below 300 ppm, the excess suspended particles being removed by physical means.  The calcite coating deposition according to the present invention has the advantage that it occurs at the rate of above 5 microns/h and even above 50 microns/h, maintaining a completely corrosion-free system during the coating.  The method is applicable to lead pipes, cement mortar linings or asbestos pipes.

Abstract: QUATERNARY SIGNAL REGENERATOR             Abstract A digital signal regenerator receives a four-level input signal, amplifies, reshapes, and retimes that signal into a regenerated four-level output signal. Awide range controlled equalizer amplifies and reshapes the four-level input signal into an intermediate signal. A variable all-pass circuit varies the shape of theequalizer's phase characteristic to optimally shape the four-level signal as a function of the maximum amplitude of the four-level input signal. The reshaped four-level signal is retimed and amplified into the regenerated four-level output signal. This enables multiplying the rate at which information is transmitted for a selected pulse rate in the transmission line.

Abstract: Abstract A steering apparatus for artificially establishing steering feel in a steering system not having a mechanical connection between the steering wheel and the steerable wheels.  The apparatus includes a hydraulic steering motor connected to the steerable wheels.  A steering wheel position sensor and a steerable wheel position sensor each produce an electrical signal respectively indicative of the steering wheel position and the position of the steerable wheels,  An electronic control unit monitors the sensor signals and controls a solenoid operated directional control valve to steer the vehicle in a direction and at a steering rate in response to the monitored signals.  An electromagnetic friction brake is connected to a support and to the input shaft and is controlled by the electronic control unit to provide steering feel. The friction brake includes an armature fixed to the support and a brake member secured for rotation with the input shaft via a spline connection.          The brake member is movable toward the armature under the influence of the magnetic field generated by the armature.  The degree of mechanical coupling between the armature and the brake member is proportional to the magnetic field strength.  Steering feel is controlled by the electronic control unit in response to the difference between the desired steering direction, as determined from the steering wheel position sensor, and the actual steering direction, as determined from the steerable wheel position sensor.

Abstract: AN OPTICAL MIXER FOR UPCONVERTING OR   DOWNCONVERTING AN OPTICAL SIGNAL            Abstract The present invention relates to an optical upconverting or downconverting gain or loss modulating mixer and a receiver for subcarrier optical communication systems using this mixer. The optical mixer can be formed, for example, from an optical amplifier including a semiconductor laser chip comprising a p-n junction with an active region channel formed along the junction. An optical signal received from the communication system is directed into one end of the channel, and a combination of a D-C bias signal and a local oscillator signal is concurrently impressed on the chip to gain-modulate the received optical signal and produce an upconverted or downconverted output signal. In the receiver, the upconverted or downconverted output signal from the gain-modulated optical amplifier is detected by a photodetector, amplified if necessary, filtered and then demodulated before transmission to the output utilization device. A loss modulator provides similar optical mixing but does not provide a gain to the output signal.
