Abstract: A method for producing spagyric essences in the form of standardized products with defined alcohol contents in respect to the dried residue of plants used in that method.      The components of a spagyric essence which are important from the spagyric point of view (fermentation alcohol, volatile aromatic substances and soluble mineral salts) are obtained totally and in pure form. The production process is distinguished by a way to prepare the yeast fermentation which prevents the development of undesirable micro-organisms, by gentle vacuum distillation, by complete incineration with exhaustive extraction of the mineral substances, and by different methods for removing impurities which were also extracted. Spagyric essences or primary tinctures are used as medicaments in human and veterinary medicine.

Title: Statistically compensated optimization system
Inventor: DELEEUW PETER H
IPC: G06Q10/04
Filed: 1992-06-23
Granted: 1995-04-11
Abstract: A method of optimizing the yield of useful material cut from a piece of raw material, such as lumber, includes considering different cutting options for cutting the piece, identifying different potential yields obtainable for each cutting option, determining the relative probability of obtaining each potential yield, and determining the-relative value of each cutting option, preferably by averaging the potential yields for that option where each potential yield is statistically weighted by its relative probability.  By comparing the relative values, the highest-valued cutting option is identified and cutting of the piece is performed in accordance with such option.  The relative probabilities for the respective possible yields are preferably deter-mined by empirically measured statistical attributes that characterize the uncertain variables that affect these yields and by grouping the uncertain variables into statistically significant classes, each class correspond-ing to a respective yield, where the relative frequency of each class is determined from the underlying statis-tical attributes.  Alternatively, the relative probabil-ities are determined by using statistical attributes that are based on a statistically expected distribution.

Abstract: In  an  optical  information  recording  and reproducing  apparatus,  the  recording  operation  is interrupted  when  an  information  pit, dust,  scratch, stain, etc.  is present on an optical recording medium. However,  the  recording  operation  is  resumed  and  kept continued when a dust,  scratch,  stain,  etc.  other than the  information  pit  is  present  on  the  medium.    The apparatus comprises a double recording detecting circuit for detecting a pseudo double recording signal generated by a dust, scratch, stain, etc. on the medium at a period of a recording operation; and a recording signal supply circuit for interrupting the recording operation when the double  recording  detecting  circuit  detects  the  pseudo double recording signal to switch the recording period to a monitor period, for maintaining the interruption of the recording operation when a real double recording signal generated  by  an  information  pit  is  detected  at  the monitor period, and for resuming the recording operation when the real double recording signal generated by an information pit is not detected at the monitor period. After  the  recording  operation  has  been  resumed  and further when the pseudo double recording signal generated by a dust, scratch, stain, etc.  still remaining on the medium is detected, the monitor and recording periods are repeated  alternately.    However,  after  the  medium has become free from a dust, scratch, stain, etc. finally and therefore the real and pseudo double  recording signals are not both generated, the recording operation is kept continued normally.

The stator housing may be made from a molten metal such as cast iron or aluminum, and has an annular wall having integral outwardly extending longitudinal cooling fins, mounting foots pads and a conduit box support pad. The lost foam process enables the cooling fins to have a greater effective cooling fin height to housing diameter ratio and greater effective cooling fin height to housing annular wall thickness ratio than obtained with prior sand casting processes.        The greater height fins provide increased strength and rigidity for the annular wall which can be made radially thinner than prior stator housing or frames of similar size. Substantial savings in material and labor are realized by the stator housing.

IPC: H04N5/44
Filed: 1993-04-21
Granted: 2000-12-12
Abstract: A high-performance television receiver synchronously detects the picture IF  signal. A synchronous impulse noise in the IF signal generates either positive-going noise or negative-going noise in the video signal supplied from a synchronous video detector, which noise is subsequently replaced by a value of video signal occurring previous to the impulse noise in the following manner. The video signal contaminated with impulse noise is supplied as input signal both to an impulse noise detector and to a delay line. The output signal from the delay line, delayed by about 240 ns, is supplied as the signal for tracking by a track-and-hold circuit. The detected impulse noise signal is used to actuate the hold condition in the track-and-hold circuit. By stretching the pulse from the impulse noise detector for the 600-800 ns duration overlapping the duration of most impulse noise, the track-and-hold circuit replaces most impulse noise with previously stored values of the delayed video signal. This not only generally avoids the appearance of white impulse noise and ensuring black impulse noise in the televised picture, but avoids the application of impulse noise to the chroma channel receiving synchronously detected video signal as its input signal. Shock excitation of the chroma channel is accordingly avoided, so chroma "twinkle" does not appear in the televised picture.

Title: Method and apparatus for manufacturing lenses using thin coatings
Inventor: BLUM RONALD D
IPC: B29C43/20
Filed: 1992-10-16
Granted: 1998-06-09
Abstract: A fast, relatively inexpensive method and simple is disclosed for producing a finished plastic multifocal or progressive lens from a preformed lens which has a predetermined lens correction (i.e., curvature or prescription) at its optical center.  The method comprises providing a mold; providing an optical quality resin composition; providing a preformed plastic lens contacting the preformed lens with the mold such that the surfaces of the preformed lens and the mold form a cavity enclosing the resin composition; and curing the resin composition.  The cavity formed by the preformed lens and the mold is shaped, among other purposes, (1) to correspond to the desired change in curvature, and (2) such that the lens correction at the optical center of the resulting lens is substantially the same (preferably the same) as the predetermined lens correction at the optical center of the preformed lens. The preformed lens may also be cast with a thin nonprescription layer which acts as a carrier for the multifocal or progressive region of the finished lens.  The methods disclosed allow casting of lenses without employing expensive conventional optical gaskets. The methods also allow for simpler relocation of the optical center to the proper position with respect to the multifocal or progressive prescription, preferably without using conventional optical gaskets or optical center movers.

Abstract: An apparatus for cleaning a charge retentive surface of a photoreceptor which includes a rotating brush for cleaning the charge retentive surface of a photoreceptor. A spring or other means is used to maintain constant, uniformly distributed contact between the charge retentive surface and the rotating cleaning member together. The use of one or more pressure rollers to maintain the cleaning brush next to the photoreceptor belt can prevent undesirable friction, heat and/or static charge buildup adjacent to the photoreceptor, and can prevent photoreceptor jamming and other malfunctions. The resulting self regulating cleaning brush contact improves photoreceptor cleaning effectiveness despite brush aging, bristle wear or set, or other factors effecting the radius of the cleaning brush or its relative positioning in the photoreceptor cleaning assembly. The present invention results in the uniform distribution of the contact pressure on the photoreceptor, which may monitored and/or be controlled. A cleaning bar for dislodging debris that might otherwise remain attached to the rotating cleaning brush may also be biased towards and movable relative to the rotating brush.
