Title: Low energy consumptive device for acquisition of data relating to abnormal heart muscle activity
Inventor: BIBLE CHRISTOPHER T
IPC: A61B5/308
Filed: 1991-11-01
Abstract: ABSTRACT A portable low energy consumptive device and method for monitoring  heart  muscle  electrical  activity  includes  a plurality of electrical contacts and a signal processing unit.          The contacts receive an electrical signal generated by the heart muscle of a patient and deliver the signal in analog form to the signal processing unit which contains an analog signal processor, an A/D converter, a digital microprocessor, and a memory.  The unit triplicates the signal and processes each of the three signals separately in the analog signal processor.  The processed signals are then converted to three distinct digital data sets, the first of which is stored in memory  while  the  remaining  two  are  processed  in  the microprocessor to determine ST segment characteristics useful in diagnosing myocardial  ischemia.   Although the device operates continuously, only a portion of the operating time is devoted to digital data processing which has a higher energy demand.  The remainder of the operating time is devoted to analog signal processing or data storage which have a lower energy demand.     Patent: 10977.2

Abstract: A new process for the preparation of water-soluble diphosphines derived from biaryl compounds is disclosed.  The process comprises treating biaryl compounds of the formula   in which A is, for example, alkyl or cycloalkyl, R1  is, for example, hydrogen or alkyl or alkoxy radical having 1 to 14 carbon atoms, m is an integer from 0 to 5 and n is an integer from 0 to 4, with a solution of SO3 in sulfuric acid at a temperature from 0 to 60°C.  The mixture, which is allowed to react at 20 to 60°C over a period of 1 to 60 hours with vigorous stirring, is then diluted with water while maintaining a temperature of from 0 to 20°C and the product is isolated.  The process is carried out under mild conditions, under which the formation of oxidation products, such as phosphine oxides, is largely suppressed.  The process is economical and can be easily carried out industrially.

Abstract: ABSTRACT       Laundry facility management system comprises a laundry service device, controlled by an operating control; and a local controller connected to the service device and a central controller, connected together for the transfer of information between them.  The local controller stores a current device rate, representing current cost of service provided by the connected service device, and reads a card indentifier provided on and uniquely identifying a presented service card  Local controller request means derives from a read card identifier and from the current device rate an authorization request, and transmits it to the central controller.  The central controller receives an account balance payment message providing a particular card identifier and a payment value, and stores account balance signals for at least one account, each account being uniquely indexed by a particular card identifier.  Account managing means responds to a received authorization request to update the account balance indexed by the card identifier of the authorization request by the current device rate value of the authorization request, and transmits an authorization message to the local controller.  The local controller responds to a received authorization message to output a control signal on the control output to control the service device operating control to provide the requested service.  The account managing means responds to a received account balance payment message to credit the stored account balance indeed by the particular card identifier by the payment value of the received account balance message.

Title: Roofridge-ventilation system
Inventor: GREBE GERHARD
IPC: E04D13/17
Filed: 1990-10-06
Abstract: ABSTRACT       A roofridge-ventilation system on roofs, having a roofridge-venti-lation cap 1 disposed below the ridgetiles 4, comprises a gap 7 facing the longitudinal edges, in which gap fittings are made which form the entering air to vortices or deflect it. The roofridge-ven-tilation cap 1 can comprise devices for completely closing the gap 7 in such a way that the gap 7 only exists on the leeward side. By such means, on the leeward side of tilted roofs, a stable vacuum region can be established. By means of the thus created suction, stale air can be guided leewardly out of the inner space of the roof and out of the airing gaps into the outer region (fig. 1).

Inventor: SCHMITZ PETER J
IPC: E03D1/30
Filed: 1992-05-29
Abstract: The water-saving devices for a toilet is of the type which float up and down on the overflow tube, where downward movement of the device brings it into contact with the flapper valve at the bottom of the toilet tank in order to close it prematurely, thereby reducing the amount of water used for the flush.  Upper and lower opposing cup shapes are integrally mounted around respective cylindrical sleeves, the sleeves being adapted to slide one within the other to adjust the spacing between the opposing cup shapes.  One sleeve has an inset area with a longitudinal row of spaced holes or indentations.  The other sleeve has an elongated tongue having a raised dimple which engages one of the spaced holes or indentations to set the spacing between cup shapes.  A number of ribs or vanes are molded as part of the upper cup, and act to deflect the float rod to reduce any possibility of the float rod catching under the upper cup.  The cup shapes are not cylindrical, but instead have flat vertical surfaces relatively close to the sleeves, so that the device can still be installed in tanks where the overflow tube is close to the tank wall.  A C-shaped shell snaps onto the lower cup and is rotatable between a first position in which it leaves the flat surface exposed, and a second position in which the lower cup in effect takes on a circular shape.

Title: Putative target for an immunotherapeutic approach to prevent, and stop the neurological and other symptoms of lesch-nyhan syndrome in humans: reconstructed cdna and protein antisense to the human hprt gene
Inventor: PREDDIE RICK E
IPC: C07K14/47
Filed: 1993-01-25
Abstract: ABSTRACT            Point mutations and/ or deletions in the human hypoxanthine-guanine phosphoribosyl transferase (HPRT) gene is believed to be the cause of Lesch-Nyhan syndrome  in humans;  however,  the disastrous neurological symptoms which are characteristic of this   disease   cannot   be   easily   explained   by   these mutations/deletions or even by the complete loss of the gene. There is no known cure for the disease. We reconstructed a cDNA (chprt) which is 100% homologous to a region of the antisense strand of hprt mRNA. The cDNA encodes a 30 amino acid protein (phrpt)  which appears  to be  an  intracellular  activator of proteins involved in human neurological diseases. Because of the antisense relation with hprt mRNA, phprt cannot be expressed in humans carrying a normal wild type hprt gene; however, mutations in critical  regions  of  the  hprt gene  can  stop  antisense repression and permit expression of phprt and the appearance of the pathophysiological symptoms of Lesch-Nyhan disease.  The antisense protein is a very good target for immunotherapeutic reagents to stop the devastating neurological processes caused in humans afflicted with Lesch-Nyhan.
