Title: Multiple electrode deployable lead
Inventor: BUSH MARY E
IPC: A61N1/05
Filed: 1991-09-04
Abstract: MULTIPLE ELECTRODE DEPLOYABLE LEAD     ABSTRACT OF THE DISCLOSURE            An implantable defibrillator lead comprises a flexible,  conductive lead member having proximal and distal end portions.  The distal end portion defines a plurality  of  separate,  curvilinear  electrodes which naturally  extend  laterally  outwardly  in  a  curved arrangement from the remainder of the lead.  However, by desired  means,  the  curvilinear  electrodes  may  be temporarily extended out straight, substantially parallel to the axis of the remainder of said lead member, to facilitate  implantation  of the  lead.    This may be preferably  accomplished  by  a  flexible  sheath  that encloses the lead member in longitudinally slidable relation.

Title: Platelet specific immunoconjugates
Inventor: BODE CHRISTOPH
IPC: A61K47/48
Filed: 1990-04-03
Abstract: Immunoconjugates are described comprising a platelet-specific antibody or antibody fragment coupled to a thrombolytic agent. The antibody, or fragment thereof, is, preferably, specific for the glycoprotein IIb/IIIa receptor in its complexed form. These antibodies block ligand binding to the receptor, thereby preventing platelet aggregation which has been implicated in the formation of thrombi. The thrombolytic agent, either in natural or recombinant form, promotes fibrinolysis in the thrombus. These immunoconjugates are useful in anti-thrombotic therapy.

Abstract: A spray nozzle assembly including a body and a nozzle tip having a ball-shaped mounting end for selected swivel positioning within a socket in the body. The nozzle tip contains a vein for imparting swirling movement to liquid passing through the nozzle assembly such that the discharging liquid has a hollow cone spray pattern. The vein has a pair of liquid flow passageways each having a diameter of at least .22 the diameter of the ball-shaped mounting end of the tip and at least .32 the diameter of the vein for permitting the free passage of liquids with relatively larger solid materials than heretofore possible with comparably sized nozzle elements.

Title: Method for reprocessing thermoplast-coated packing materials and thermoplast material for further processing
Inventor: MENGES WILHELM
IPC: B03B9/06
Filed: 1991-12-24
Abstract: ABSTRACT            A method is described for reprocessing substantially used generally bilaterally plastic-coated beverage cartons or cardboard.  The beverage cardboard is first comminuted with cutting tools in such a manner that isolated sheet pieces of about 5 cm diameter are obtained which in a subsequent decontaminating wash can be flushed as far as possible from all sides.  The rinsing agent is withdrawn from the process and supplied directly to a biological clarifying.  The precomminuted and washed cardboard is then divided in a second comminuting step into small sheet pieces of about 8 mm diameter and either simultaneously or thereafter subjected to disintegrating forces, the plastic layer particles being detached from the fibrous material substrate.  The suspension thus disintegrated is separated into a fibrous fraction and a thermoplast foil fraction. After further cleaning and sorting steps the thermoplast is dried and regranulated for recycling.  The substantially long-fibre fibrous component is beaten and preferably used in the production of corrugated board raw paper.  As a special step, a certain amount of finely ground thermoplast material may be fixed to the fibrous material.

Filed: 1992-02-12
Abstract: METHOD FOR CONTROLLING PROCESSOR CLOCK SIGNAL AND INFORMATION PROCESSING SYSTEM                            ABSTRACT      In order to ensure that an allowed time to stop a processor, or an allowed time to delay an operation of the processor is determined to  stop the  supply of a clock signal to the processor, the supply of the clock signal to the processor is controlled by a program that runs in the lowest priority under a multitask operating system.   In providing a clock control program, the latter runs only when no other tasks run.  Thus, the supply of the clock signal to the processor can be controlled on or off for each time interval indicated by the system timer.

Filed: 1992-04-29
Abstract: ABSTRACT OF THE DISCLOSURE    A woven fabric for covering a tooth part formed on a belt body of a synchronous belt is woven with a lengthwise yarn and a widthwise yarn. The lengthwise yarn is made of a crimped yarn of synthetic fiber or a covering yarn in which a crimped yarn of synthetic fiber is wound around an elastic cord yarn.

Abstract: Divulgation d'une source d'ions produits par électrospray, conçue pour être rapidement et facilement connectée à des analyseurs de masses commerciaux servant à l'analyse par spectrométrie de masse de molécules organiques. L'électrospray est réalisé dans l'air ambiant (14), et les ions et autres espèces chargées pénètrent dans l'analyseur de masses (31) par l'intermédiaire d'un long tube métallique capillaire (11) et trois étages de pompage différentiel. L'utilisation du long tube (11) permet : a) une injection pratique des ions dans l'analyseur de masses (31); b) l'optimisation du spray par visualisation directe dans l'air (11-14); c) un transfert de chaleur efficace et contrôlé vers les gouttelettes; et d) un pompage efficace de la région (32) entre la sortie du capillaire et le récupérateur (28). La désolvatation des ions solvatés est réalisée à l'aide d'une combinaison de transfert de chaleur contrôlé vers les gouttelettes chargées, au cours de leur passage dans le tube (11), et d'activation collisionnelle dans une région de pression réduite (32). La désolvatation dans ce système ne fait pas intervenir l'utilisation d'un fort contre-courant de gaz chauffé. Ce système peut aussi être utilisé afin d'obtenir le spectre de fragmentation collisionnelle des ions moléculaires. L'utilisation d'un tube capillaire métallique (11) permet d'éviter les complications dues au gain de charge qui existent lorsqu'on utilise des tubes capillaires diélectriques.
