Abstract: A continuous solvent pulping process is practiced with oxygen free gas (e.g. nitrogen) purges of all major treatment vessels (23, 24, 85, 103, 105) during the time when the process is arrested or terminated. The wood chips or other cellulosic fibrous material to be pulped is steamed in a first horizontal steaming zone (23) at a pressure of about 10-20 psi, and then in a second horizontal steaming zone (24) at a pressure of about 20-75 psi. Gases, including vaporized solvent (e.g. ethanol or other alcohol) are vented (via 30, 36) from the steaming zones, and solvent is added (at 39) to the steamed material prior to feeding to a high pressure feeder (11) . The high pressure feeder introduces the material into the top of a single digesting vessel (12), liquid and chips being separated at the top of the digester vessel without mechanical means that could cause a spark. Lignin containing liquid is withdrawn from a central portion (14) of the digester and passed through flash tanks (51-53) and ultimately for lignin and alcohol recovery. Washing -- which also may be practiced using solvent pulp from a batch system -- is accomplished by first continuously passing the pulp to a pressure diffuser (85), then to a first multi stage drum displacer washer (103), and then to a second multi stage drum displacer washer (105). <IMAGE>   <IMAGE>   <IMAGE>

Abstract: PCT No. PCT/EP91/00480 Sec. 371 Date Nov. 24, 1992 Sec. 102(e) Date Nov. 24, 1992 PCT Filed Mar. 14, 1991 PCT Pub. No. WO91/14711 PCT Pub. Date Oct. 3, 1991.The invention relates to a process for the production of a multicoat coating in which an aqueous transparent topcoat composition containing a polyacrylate resin as binder is employed. The polyacrylate resin can be obtained by adding, either successively or alternately in part amounts, a mixture of a carboxyl-containing ethylenically unsaturated monomer (a1) and a monomer (a2) free from carboxyl groups and a mixture (b) consisting of (meth)acrylic acid esters which are free from carboxyl groups, of hydroxyl-containing ethylenically unsaturated monomers and, if appropriate, of other ethylenically unsaturated monomers to an organic solvent and carrying out a polymerization in the presence of a radical-forming initiator and, at the end of the polymerization, neutralizing the resultant polyacrylate resin and dispersing it in water. The type and amount of (a1), (a2) and (b) are chosen so that the polyacrylate resin has a hydroxyl value of 40 to 200, an acid value of 20 to 100 and a glass transition temperature (TG) of -40 DEG  C. to +60 DEG  C.

Inventor: VAITEKUNAS JEFFREY J
IPC: A61B8/06
Filed: 1993-11-12
Abstract: Ultrasonic sensing systems are incorporated into surgical instruments to monitor operational fields defined by distal ends of the instruments. The instruments include proximal ends for their activation typically including one or a pair of handles which a surgeon grasps and operates, for example by squeezing the handles together or by pivotally moving a trigger portion of the handle relative to a fixed portion of the handle. Circuitry for performing ultrasonic sensing preferably is enclosed in housings defined within the handles of the proximal ends of the instruments. Wiring, preferably running through the instruments, connects the circuitry to transducers formed in or mounted on the distal ends of the surgical instruments. The transducers direct ultrasonic energy to the operational fields defined by the distal ends of the instruments and receive ultrasonic energy reflected from the operational fields. The direction for transmission and receipt of ultrasonic energy is determined by acoustic lenses, angularly oriented transducer mounts or a combination of the two. Signals representative of the tissue or contents of the operational fields of surgical instruments drive audible signal generators or preferably tactile transducers to inform the surgeon of the contents. Tactile transducers are mounted for access by the surgeon, preferably on the handles of the surgical instruments.

Abstract: The rotary drive device for the drive of the sleeve of an electrical discharge machining unit comprises an electric motor, reversible with regard to the direction of rotation, and a reduction gear unit allocated to the electric motor. This reduction gear unit has a pinion (41) and two gear wheels (33, 35) rotatably mounted relative to one another. Both the gear wheels (33, 35) mesh with the pinion (41). One of the gear wheels (35) is under the effect of a torsion preloading force. A first gear wheel (33) of the two gear wheels of the reduction gear unit is coupled to the sleeve (20, 21) in such a way as to be locked in terms of rotation, while the second gear wheel (35) is rotatable relative to the sleeve. Such a rotary drive device works with little effort in both directions of rotation absolutely free of play, any wear which may arise being automatically compensated for. <IMAGE>

The apparatus includes a microwave generating device coupled to a waveguide having a means for causing multiple microwave propagation modes prior to directing the microwave into the reaction vessel. The waveguide is mounted to the reaction vessel and directs the microwave in an inclined-angular fashion, thereby generating a helical reflection pattern within the vessel's interior and providing a uniform heating of said interior. An isolation means is also provided, positioned between the microwave generating device and the reaction vessel, which incorporates a quartz window and a sealing means capable of compensating for any disparity in thermal expansion coefficients between the quartz and the material used to house the quartz. <IMAGE>

Abstract: A graphic data-acquisition system which employs an active tracking system provides a retrofittable apparatus for converting a substantially planar surface into an electronic data capture device, in which the components of the system are readily retrofittable, at relatively low cost, to a wide variety of otherwise conventional writing-surface structures, such as so-called dry-erase whiteboards. Conventional triangulation techniques are used to track the position and motion of a writer or eraser. An encoding facility associated with the writing implement provides the ability to distinguish whether the writing implement is used for marking or an as erasing implement, as well as determining the nature or character of written line width or eraser swath. A data stream thus generated can be used in a variety of ways, such as for example, to feed information into the memory of a digital computer, and/or to feed information for transmission to remote stations.
