Patent CA-2287531-A1 (CA)
Inventor: ALBRECHT THOMAS
IPC: A61P31/20
Filed: 1998-03-02
Abstract: An important aspect of the present invention is a method for inhibiting proliferation of a DNA virus dependent upon events associated with cell proliferation for replication. The DNA virus includes any of the herpesvirus family, and most particularly human cytomegalovirus. The method involves administering prophilactically or therapeutically effective amount of a cyclin-dependent kinase inhibitor to a patient or animal. The therapeutically effective amount is that amount sufficient to inhibit cellular Cdk activity to an extent impeding viral replication. A preferred inhibitor is roscovitine although olomoucine or other Cdk inhibitors are also acceptable. Once the knowledge of the present invention is available, it is believed that many other Cdk inhibitors may be developed for the use and that these too well be useful for the therapy and prophylaxis of DNA viral infections. Other herpesviruses such as herpes simplex, for example, and other cytomegalovirus are also treatable by the procedures of the present invention. The therapeutically or prophylactically effective amounts of the inhibitor usable for present invention are generally between about 0.1 µg/kg body weight to about 1000 µg/kg of body weight, although amounts beyond these limits may be appropriate, depending on the inhibitor's effectiveness and toxicity. More effective Cdk inhibitors would, of course, be effective at lesser concentrations. Likewise, weaker Cdk inhibitors would require greater amounts.  A Cdk preferably inhibited is Cdk2, most preferably cyclin E/Cdk2.

Abstract: The invention relates to a wind energy installation comprising a rotor with at least one blade for the conversion of wind flow energy into mechanical energy, a regulating device for individual regulation of at least one rotor blade, a generator for the conversion of mechanical energy provided by the rotor into electric power, and an active connection between the rotor and the generator so that the mechanical energy can be transferred from the rotor to generator. The aim of the invention is to avoid such problems as those mentioned in the description and to provide a wind installation whereby the loads which can occur in partial areas of the surface of the rotor as a result of local transitory yaks in wind speeds are reduced.  This is achieved by providing the above-mentioned wind energy installation with means of measurement such as an anemometer (44) placed on each rotor blade to determine the momentary load of one part of the wind energy installation, in addition to control means which determine a desired position for at least one rotor blade in order to react to said momentary load and to adjust the rotor blade accordingly using the regulating device; as well as joints and fasteners which connect the regulating device and means of measurement to the control means.

Title: Apparatus and method for modeling behavior of expansion boards in a computer system
Inventor: ANDERT GLENN P
IPC: G06F9/445
Filed: 1999-01-28
Abstract: When an expansion card is installed in a computer system using a computer viewer, an object is created by the computer viewer to represent the card. The computer viewer uses the card object to examine the card for I/O functions present on the card and to obtain resource requirements for each function. The resource requirements are also provided to a resource conflict resolver object which attempts to assign resources to each I/O function on the cards. If the resource conflict resolver is successful in assigning resource to each I/O  function, then the resource assignments are also stored in objects. The computer viewer then uses the card objects to store the resource objects in a persistent storage. During a later system boot operation, the booting system creates bus and card recognizer objects which identify expansion buses and cards present in the system and retrieve the function resource objects from the persistent storage to represent each expansion card.

Inventor: AUER GERHARD
IPC: C01F11/46
Filed: 1999-03-17
Abstract: The invention relates to a method for producing gypsum and an iron oxide pigment from the waste acid resulting from the production of titanium dioxide according to the sulfate process. The invention is characterized in that in an initial step the waste acid is partially neutralized using a calcium compound, resulting in the precipitation and possibly direct separation of gypsum. The remaining solution is neutralized further in a second step, with precipitation of a precipitate containing Ti, Al, Cr, V and possibly Fe(III). From the iron sulfate-containing solution obtained after separation of the solid, an iron oxide pigment is produced in a third step by addition of alkaline compounds and possibly ammonia and an oxidizing agent. By adding CaO and/or Ca(OH)2 ammonia is released from the (NH4)2SO4-containing solution obtained after separation of the iron oxide pigment.
