Abstract: THERMOPLASTIC DUPLICATION PLATE MAKING METHOD          Abstract of the Disclosure A method of manufacturing thermoplastic duplication plates having a relief image transcribed thereto from a matrix which has a relief pattern in complemental relation to the transcribed relief image.  To this end, a thermoplastic resin sheet is fed onto a rotating cylinder heated to a predetermined temperature and is then transported towards a transcription station while it clings to the outer peripheral surface of the cylinder.  At the transcription station, the thermoplastic resin sheet then heated to a semi-fluidized state is registered or aligned with the matrix being moved in a linear direction substantially tangential to the outer peripheral surface of the cylinder.  During passage through the transcription station, the thermoplastic resin sheet is transferred onto the matrix with the material penetrating deep into indentations in the matrix.  Therefore, the thermoplastic resin sheet is cooled and subsequently separated from the matrix, thereby completing the thermoplastic duplication plate.  This method has the advantage that the relief image can be transferred from the matrix to the thermoplastic sheet substantially without reformation.

Title: Method and apparatus for the real-time, non-destructive evaluation of adhesion bonds using stress-wave emission techniques
Inventor: VAHAVIOLOS SOTIRIOS J
IPC: G01N29/22
Filed: 1976-07-22
Granted: 1979-01-23
Abstract: Abstract of the Disclosure The strength of an adhesion bond can be determined using stress-wave emission techniques. One method measures the stress-wave energy emitted from the bonding area during the compression phase of the formation of the bond and compares this measurement with a predetermined substantially linear relationship between the emitted stress-wave energy and the strength of the adhesion bond. For more accuracy, a second method measures the stress-wave energy during both the compression phase and a pressure-relief interval, determines the difference between the two measurements, and compares the difference value with the substantially linear relationship. An alternative to the second method substracts a predetermined threshold value from the pressure-relief interval measurement, reduces the compression phase measurement by the excess determined by said substraction step, and compares the reduced compression phase measurement with the predetermined substantially linear relationship to determine the strength of the bond.

Abstract: ABSTRACT OF THE DISCLOSURE This disclosure depicts a novel method and apparatus for dispensing a cement onto the seal land of a color CRT funnel.  In particular, this method and apparatus is intended for dispensing cement onto a funnel seal land which defines a convex curved plane, at least a curved segment of the seal land lying on a predetermined radius.  The method comprises holding the funnel in a neck-down position, providing a substantially stationary cement dispensing nozzle and, in order to dispense cement on at least the segment of the curved seal land, swinging the funnel about the origin of the radius of the seal land segment such that the seal land segment passes under the cement dispensing nozzle at a substantially constant predetermined distance beneath the nozzle and in a substantially horizontal attitude.  Apparatus is disclosed for implementing the described method.

Abstract: ABSTRACT OF THE DISCLOSURE           A tape speed measuring circuit for use with quadruplex video recorder/reproducers, which identifies the speed at which the recording was made to allow auto-matically switching to the correct speed upon playback.          The circuit measures the ratio of control track frequency relative to the capstan tach frequency to obtain the re-corded tape speed.  A commutating filter means responsive to the capstan tach signal allows the accurate extraction of the desired control track signal component at all tape speeds,  Divider means counts the number of tach pulses received during a selected time period.  If the number of pulses is more or less than a pre-selected quantity, a high or low logic level respectively is generated commen-surate with the standard 15 or 7-1/2 inches/second recorded tape speed.

Abstract: ABSTRACT OF THE DISCLOSURE            Metallic derivatives of anthracycline glycosides such as doxorubicin and daunorubicin are prepared by admixing divalent or trivalent metal cations, preferably Fe(III), with the glycoside and adjusting pH to promote chelation of the metal by bidentate ligands of the glycoside.  The derivatives are isolated in essentially monomeric form, and preferably lyophilized for later reconstitution immediately before use in the treatment of neoplastic diseases.  As compared with the parent glycosides, the derivatives exhibit greatly diminished cardiotoxicity and less general, hematological and digestive toxicity as well.  At the same time, the antinioplastic efficacy   of the derivatives appears to be approximately equivalent to that of the parent glycoside on a mg. to mg. basis.          As a result, the therapeutic index of the derivative is greatly elevated over that of the parent, since the derivative may be safely administered in greater quantities.

It also relates to a process for the preparation of these compounds.  The compounds of formula (I) may be used for the same Therapeutical indications as natural prostaglandins with respect to which,however, they offer the advantage of being no substrates for the enzyme 15-prostaglandin dehydrogenase, which as is known, quickly inactivates natural prostaglandins, and, moreover, are characterized by a more selective therapeutical action. The compounds of formula (I) furthermore inhibit the use of natural prostaglandins as substrate by the same enzyme. In particular the compounds of the invention have selective leuteolytic, abortifacient and labor-inducing activity and extremely low undesired gastro-intestinal effects.
