Granted: 1978-08-22
Abstract: ABSTRACT OF THE DISCLOSURE             A PVC film with a non-tacky microcell surface on one side is provided which does not adhere to any smooth surface such as photographs, slides, negatives and other materials requiring covering for protection such as in photo-albums, slide-sheets, negative-albums, and X-ray film covers where a slightly opaque surface is needed to protect the materials from damage caused by direct light.  A film is specifically treated to provide microcells on one surface thereof which avoid adherence of the film to smooth surfaces.  These microcells are made possible by application means or mechanical means.  The microcells formed are an integral part of the original film, and cannot be defined as to structure or size since the same are of an irregular nature.

Abstract: ADJUSTING MECHANISM FOR SKI BINDINGS                 ABSTRACT OF THE DISCLOSURE    A device for mounting a binding component onto a ski and providing for longitudinal adjustment thereof on and with respect to the ski.  A carriage for carrying the bind-ing component is arranged for slidable adjustment along a ski.  Either the carriage or a device fixed to the ski car-ry a toothed rail and the other thereof carries a toothed locator positioned for crosswise motion relative to the ski into and out of engagement with the toothed rail. A light spring holds the locator in normal engagement with the toothed rail.  A manual device is provided for disengage-ment of the parts upon moving of the locator crosswise of the ski aginst the spring.  This enables the spring to be relatively light inasmuch as it functions only to hold the locator in rail engaging position and the locator may be easily disengaged by simple direct movement  thereof against the spring.  After adjustment of the carriage is completed, the locator may be caused to reengage with the toothed rail by releasing same to permit the spring to move the locator back to a position effecting such engagement.

Abstract: DISPOSABLE DENTAL TRAY FOR TOPICAL APPLICATION  OF FLUORIDE GEL AND OTHER DENTAL MEDICATIONS     Abstract of the Disclosure A disposable applicator tray, for topical applica-tion of fluoride gel and other dental medications, in the form of an arcuate mouthpiece having a U-shaped cross-section and comprised of flexible polymeric foam material.  The interior channeled recess of the tray is anatomically con-toured to fit respectively over either of the upper and lower teeth with the walls of the tray contacting the adjacent periodontal tissue.  The flexibility of the tray provides a relatively snug seal between the tray perimeter and the periodontal tissue so as to prevent excessive loss of fluoride or other medication contained in the tray and the contamination and dilution thereof with saliva.  The applicator tray, which can also serve as a protective mouth-piece for use during athletic activities, is vacuum formed in quantity from a sheet of inexpensive polymeric foam material, thereby permitting it to be economically disposed of after a single use.  The bottom surface of the interior recess of the applicator tray, against which the biting edges of the teeth bear when the tray is inserted in the mouth, is provided with indentations anatomically configured to mate with the mouth's dentition pattern and the walls of the tray are similarly anatomically configured so as to provide a comfortable, natural fit and a more thorough and extensive contact of the dental medication with the teeth surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus is described for receiving a data streams incorporating a self-clocking Manchester code.  The data streams is applied to monostable multivibrators which produce pulses at each positive-going and negative-going transition in the voltage level of the data stream.  Output pulses from the monostable multivibrators are applied to a third monostable multivibrator which is responsive to only the positive-going pulses applied thereto; the third multivibrator produces an out-put pulse having a period greater than one-half the bit period, but less than whole bit period, of the data stream.  The positive-going voltage transition of the output of the third multivibrator is used to trigger a clock pulse which is applied to a pair of gates.  The gates enable a pair of latches to which the data stream is applied to recover data from the stream and apply the data to a shift register.

IPC: H03D13/00
Filed: 1976-02-11
Granted: 1979-01-23
Abstract: ABSTRACT      In a phase-locked loop the phase offset error arising because of imperfections in the balance of the phase comparator using a first pair of balanced diode peak detectors jointly pro-ducing a detection voltage is reduced by also using a second pair of balanced diode peak detectors responsive to the reference signal and the reference signal in opposite phase for jointly producing a compensation voltage, and an output circuit for dif-ferentially combining the detection and compensation voltages so as to produce a phase comparator output voltage substantially free from offset voltage.  The quasi-static phase error of the loop may then be reduced to very low values so that the loop is particularly suited for recovering the clock frequency from synchronous pulse signals having clock frequencies of several hundred MHz.
