Title: Oral prosthesis and method for producing same
Inventor: BRUINS PAUL
IPC: A61K6/884
Filed: 1981-11-24
Abstract: Porous implantable oral prosthesis which can be used to replicate and replace any hard tissue portion of the mouth such as bone and teeth. The prosthesis comprises sintered polymeric particles coated with a hydrophilic material. The polymeric particles vary in size so as to provide an area of relatively coarse porosity (2) where the prosthesis is intended to interface with bone tissue (6) and relatively fine porosity (3) where it is intended to interface with soft tissue (7). A process for producing such prosthesis by filling a mold with appropriate molding compounds comprised of polymeric particles and a hydrophilic monomer, sintering the particles and polymerizing the monomer by dielectric heating, removing the sintered material from the cooled mold, and placing the prosthesis in a hot liquid to remove residues is described. An entire tooth, including a nonporous crown may be produced. A process for producing a porous replica of a tooth root (1) suitable for implantation immediately after extraction of a tooth is disclosed. When extraction has taken place in the past and has resulted in the bone and gum receding, a porous implant inserted in a newly drilled hole in the patient's jaw bone may be used. A central post (5) associated with the implant projecting above the gum (7) may be used for attaching a denture, partial bridge or a crown (4). A porous implant (41) may be used for jaw bone replacement in order to improve the fitting of dentures.

Title: Automatic registration control method and apparatus
Inventor: SARGENT JACK
IPC: B41F33/00
Filed: 1983-08-31
Abstract: Registration in a multi-color printing press is controlled by printing spaced groups of registration marks (40, 42) on a running web (16), each group comprising a plurality of spaced reference color marks (40) and a plurality of controlled color marks (42), each being midway between a different pair of reference marks. A computer-based control system (22) produces quantities corresponding to the leading and the trailing edges of each mark, which are averaged to determine the midpoint of the mark, thereby avoiding errors due to differences in reflectance. Registration is determined from other quantities that measure the separations between marks. Data is collected for a predetermined number of successive marks. The collected data is analyzed to determine the start of a group, and the data corresponding to marks of that group is then analyzed to detect registration. After a correction is performed, the system idles until a predetermined length of the web sufficient to enable the effect of the correction to be observed passes the sensor.

Filed: 1984-09-04
Abstract: Procédé de moulage d'articles composites ou d'encapsulation d'un article selon lequel un article à encapsuler ou à mouler et une résine thermodurcissable et thermopolymérisable sont chargés dans la cavité d'un moule qui a été préchauffé à la température de polymérisation de la résine. Ensuite, on fait le vide dans le moule jusqu'à une pression subatmosphérique pour exposer le moule à un vide de manière à imprégner l'article avec la résine et à dégazer le contenu du moule. Le vide est ensuite libéré pour faire éclater les éventuelles boules de gaz restant dans le contenu du moule. Une pression suratmosphérique est ensuite appliquée au contenu du moule pour que la résine encapsule l'article. Les conditions de température et de pression suratmosphérique sont maintenues pendant un temps suffisamment long pour polymériser partiellement la résine et former une structure unitaire qui est ensuite démoulée. La structure éjectée du moule est soumise à un cycle de chauffage ultérieur pour polymériser entièrement la résine. Des articles composites ainsi formés sont utiles comme structures, guides d'ondes d'antennes, et pour des applications spatiales. Des composants électriques encapsulés par le procédé de la présente invention possèdent une couche de passivation de haute fiabilité.

Title: Method and apparatus for configurable line testing
Inventor: OLEK DAVID J
IPC: H04B3/46
Filed: 1985-08-19
Abstract: A method and apparatus for eliminating the need to access those telephone lines that do not have to be tested while still using the sequential line accessing capabilities of the central office switching equipment. As a result dial access time is minimized without the penalty of having to test non-operational lines. This is accomplished by creating an exceptions list which identifies each line that is not to be tested, by creating a record of the next telephone line to be tested, by comparing this record against the exceptions list. If the next line to be tested appears on the exceptions list, the record of the number of the line to be tested is again incremented and such record is again compared with the exceptions list. When a number is reached that does not appear on the exceptions list, that number is then tested, the record is incremented and the process continues. Advantageously, the record of the numbers being tested and the exceptions list are maintained in registers controlled by a microprocessor in the supervisor unit (2) described in the above referenced applications, and the comparison between the record and the exceptions list is made by that microprocessor.

Title: Liquid-liquid extractor
Inventor: GALIK GEORGE MARION
IPC: B01F25/60
Filed: 1985-08-29
Abstract: An apparatus that is useful for effecting liquid-liquid extraction by contacting a first liquid medium with a substantially immiscible heavier second liquid medium. The apparatus includes either a single mixer-settler unit (10) or two or more such mixer-settler units in series. Each mixer-settler unit (10) includes a vertically extending settling tank (48) having a top (56) and a bottom (52) with an outlet (92) for the first liquid medium near the top and an outlet (94) for the second liquid medium near the bottom. An elongated extraction column (12) extends generally vertically upwardly through the settling tank bottom (52). The extraction column (12) is open at its top with the top of the extraction column (12) below the top of the settling tank (48). A diverter (58) surrounds and extends downwardly along a top portion of the extraction column (12a). The diverter has a closed top (60) and an open bottom (64) with an annulus (62) being between the diverter (58) and the portion to the extraction column surrounded by the diverter. A mixer (18) is provided in liquid communication with the extraction column (12) for mixing the first and second liquid mediums together to form a dispersion of droplets of one of the liquid-mediums in the other liquid medium and for pumping the liquid mediums through the apparatus toward the settling tank outlets. The dispersion flows from the mixer (18) upwardly through the extraction column (12) and out its top. The dispersion then flows downwardly from the top of the extraction column through the annulus between the diverter (58) and extraction column (12) and exits the open bottom of the diverter (64) into the settling tank (48). The first liquid medium separates from the dispersion, rises to the top of the settling tank (48) and exits the settling tank from the outlet (92) near the settling tank top. The second relatively heavier liquid medium separates from the dispersion, sinks to the bottom of the settling tank and exits the settling tank from the outlet (94) near the settling tank bottom.

Title: Musical instrument sustainers and transducers
Inventor: ROSE FLOYD D
IPC: G10H3/26
Filed: 1989-05-24
Abstract: A sustainer (52) for providing sustained sounds from a musical instrument (20) has a feedback circuit (70) for converting a pickup signal representing a vibration of a string or other vibratory element (32) to a drive signal and applying drive forces to the vibratory element (32) responsive to the drive signal. The sustainer (52) is arranged to compensate for the phase lag of the pickup signal relative to motion of the vibratory element (32) and to compensate for the phase lag of the drive forces provided by the driver relative to the drive signal. The feedback circuit (70) may be arranged to provide a phase difference between the drive signal and the pickup signal such that the phase difference varies with frequency towards a drive signal leading phase difference with increasing frequency. This phase compensation provides enhanced response of the strings (32) in the fundamental mode of vibration.

Abstract: La préparation et l'isolement d'agents de contraste d'imagerie par résonance magnétique, supraparamagnétiques, biodégradables pour le compartiment vasculaire sont décrits. Ces agrégats se composent de cristaux d'oxydes métalliques supraparamagnétiques biodégradables, et ont un diamètre moyen global inférieur à environ 4000 ansgtroms. L'agent de contraste d'imagerie vasculaire préféré se compose d'agrégats de cristaux d'oxyde de fer ayant un diamètre moyen global inférieur à environ 500 angstroms. Ces agents de contraste peuvent être associés à une espèce macromoléculaire aidant, entre autres choses, à la préparation de ces matières extrêmement petites, et peuvent être dispersés ou dissous dans un milieu physiologiquement acceptable. Les milieux préférés stabilisent également les matières contre une agrégation accrue même dans des conditions de stérilisation rudes. Les oxydes de fer supraparamagnétiques biodégradables de l'invention stérilisés à l'autoclave, sont particulièrement bien adaptés pour une préparation pharmaceutique et jouissent de plusieurs avantages par rapport aux milieux de contraste d'imagerie intravasculaire tels qu'une faible osmolarité, des doses faibles, des relaxivités élevées, des longues durées de vie dans le sang, une biodégradabilité rapide, et une polyvalence en ce qui concerne une large gamme de paramètres d'acquisistion de données de résonance magnétique applicables.

Abstract: A method for producing an acidic, concentrated, polymeric emulsion that can be diluted and thereafter neutralized to provide a novel polymeric thickener is disclosed. The method comprises emulsion-polymerizing, in acidic aqueous media, a first monomer mixture which comprises an acidic moiety-containing monomer and an ethylenically-unsaturated monomer copolymerizable with the acidic moiety-containing monomer, for producing an alkali-soluble dispersion in the acidic aqueous media. The ethylenically-unsaturated monomer is selected from the group consisting of a mono vinylidene aromatic monomer, an alpha beta ethylenically-unsaturated carboxylic acid ester and its derivatives, a vinyl ester and its derivatives, an ethylenically-unsaturated dicarboxylic anhydride and its derivatives, and mixtures thereof. The method further comprises adding to the alkali-soluble dispersion-containing aqueous media a second monomer mixture which comprises the above-mentioned ethylenically-unsaturated monomer and an amino moiety-containing monomer that is copolymerizable with the ethylenically-unsaturated monomer, and then emulsion-polymerizing the second monomer mixture in the presence of the alkali-soluble dispersion, while maintaining acidic conditions of the aqueous media, for producing the concentrated, polymeric emulsion mentioned above. The concentrated, polymeric emulsion can readily be diluted. Upon being diluted, the thus-diluted polymeric emulsion, upon adjustment of pH to more than about 6.5, provides the novel polymeric thickener mentioned above.
