Title: Immunologically active proteins from borrelia burgdorferi, related test kits which contain these proteins and are suitable for detecting antibodies in test fluids, and the use of these proteins as vaccines against infections caused by borrelia strains
Inventor: FUCHS RENATE
IPC: A61K38/00
Filed: 1990-12-21
Granted: 2003-01-28
Abstract: Various immunologically active proteins from Borrelia burgdorferi have been prepared by genetic manipulation in microorganisms. To do this, the specific DNA sequences were selected from a B. burgdorferi gene bank using suitable screening methods, or were prepared directly by DNA amplification using selected hybridiza-tion probes, and were placed under the control of inducible promoters such as, for example, the lac promoter. It has been possible, owing to description of efficient purification methods for the expressed antigens, to provide the proteins in a suitable way.      These proteins can be used to produce specific and sensitive diagnostic assay kits. The specific combina-tion of the immunologically active proteins makes pre-cise diagnosis possible. Furthermore, monoclonal anti-bodies have been generated and are used as reagents for detecting pathogens directly in test samples or after cultivation. The Borrelia burgdorferi-specific DNA sequences can be employed for direct detection of the pathogen in patients' samples (for example by means of the PCR reaction).

Patent CA-2100175-C (CA)
Title: System and method for mode switching
Inventor: DOUGLAS GEORGE H
IPC: B41J29/38
Filed: 1993-07-09
Granted: 2000-07-04
Abstract: A host computer and printer and method of operation is disclosed wherein the printer is able to switch between two modes of operation. When the printer is powered up, it initializes its internal data registers and printer memory, followed by a check to see if additional firmware, in the form of a cartridge or the like, is added to the printer. If additional firmware is present, the printer turns operational command over to the additional firmware. The present invention, residing in the additional firmware, stores a complete image of the printer state, internal registers, and memory in a location that cannot be accessed by either mode of operation. The present invention compresses the data so that the complete image of the printer state, internal registers, and memory occupies approximately eight KBytes of memory. The storage location may be part of the printer memory itself, or any other suitable location. The additional firmware then returns operational control to the original firmware within the printer thus allowing the printer to operate in the first mode of operation. The host computer may cause the printer to switch to the second mode of operation by simply overwriting the internal data registers and printer memory, except for the portion of printer memory that is used to store the compressed image of the initial printer state. The printer may be switched back to the first mode of operation by expanding the compressed image to restore the printer to its initial state. From the perspective of the printer, it has just completed initialization. Thus, the printer may be easily and quickly switched modes of operation.

Granted: 1997-12-16
Abstract: A retarder control  embodying the concepts of the present invention utilizes a spool valve means having a spool valve member axially translatable between an on- and an off-position. A spring means is employed to bias the spool valve member toward its off-position. A torque converter, a cooler and a retarder each have an input means and a discharge means that are ported through the spool valve means. The retarder is selectively ported to a hydraulic return means through the spool valve means, and a modulating solenoid may be employed to feed pressurized hydraulic fluid against the spool valve member not only to move the spool valve member against the spring means toward its on-position but also to regulate the axial translation of the spool valve member in order to control the pressure at the retarder discharge that is also ported through the spool valve means. A cooler communicates directly with the converter when the spool valve member is in its off-position To the contrary, the cooler communicates directly with the retarder when said spool valve member is in the opposition. First and a second reaction sub-chambers are disposed in opposition against the spool valve member. A spring means is received within the first reaction pressurized. A modulating solenoid effects continuous communication of pressurized hydraulic fluid to the second reaction sub-chamber when the spool valve member in its on-position, and a conduit selectively communicates pressurized hydraulic fluid to the first reaction chamber.
