Patent number: 5572095Abstract: The present invention, generally speaking, provides an improved base drive arrangement for scan and/or EHT output stages in a television or video display monitor. In accordance with one aspect of the invention, by adding just a few components to an existing main base drive circuit, two power transistors may be driven, e.g. a scan output transistor and an EHT output transistor. The two power transistors are switched at the same time, allowing pulse width modulators of the scan and EHT circuits to operate on a common time base. Switching of two power transistors at the same time would usually require a quite complicated design to offset the different storage times of the two devices, thereby achieving high performance but at a considerable cost premium. The base drive circuit of the invention achieve substantial synchronization of the two transistors at minimal cost.Type: GrantFiled: July 21, 1995Date of Patent: November 5, 1996Assignee: Apple Computer, Inc.Inventor: Peter Krause

Patent number: 4307194Abstract: According to the present invention inhibitors for glycoside hydrolases, and in particular glucosidase inhibitors especially saccharase inhibitors, which are active in the digestive tract are formed by culturing organisms of the family Bacillaceae, particularly by strains of the genus Bacillus.It has also been found that certain strains of organisms of the family Bacillaceae, especially strains DSM 7, DSM 704 and DSM 675 produce the antibiotic known as 1-desoxynojirimycin. The invention therefore provides a method of producing 1-desoxynojirimycin which comprises culturing a 1-desoxynojirimycin producing organism of the genus Bacillus. Inhibitors for glycoside hydrolases and the invention includes methods for producing such inhibitors, pharmaceutical compositions containing the inhibitors and methods of treatment involving the use of the inhibitors.Type: GrantFiled: December 6, 1977Date of Patent: December 22, 1981Assignee: Bayer AktiengesellschaftInventors: Werner Frommer, Lutz Muller, Delf Schmidt, Walter Puls, Hans-Peter Krause, Ulrich Heber

Patent number: 4281934Abstract: The present mixer for construction materials, such as a bituminous sludge, has a trough with an inlet and an outlet and two mixing shafts equipped with blades rotatably supported in the trough in parallel to each other. The blades are uniformly spaced along both shafts and staggered by 90.degree. around each shaft whereby the blades of each shaft follow one another in helical succession. Simultaneously the blades form four in line rows on each shaft. The arrangement of the blades is identical on each shaft except that the helix formed by the blades on one shaft has preferably a pitch direction opposite to that formed by the blades on the other shaft since the shafts rotate in opposite directions but convey in the same direction. The spacing between adjacent blades on both shafts is the same. However, blades located in the same plane extending perpendicularly to the longitudinal axes of the shafts are always spaced by 90.degree.Type: GrantFiled: August 29, 1979Date of Patent: August 4, 1981Inventors: Ulrich Krause, Peter Krause

Patent number: 4274425Abstract: In a device for measuring redox gases, such as alcohol, in a person's breath, a disposable tubular mouthpiece forms an elongated flow passage and is displaceably securable in a measuring head. The mouthpiece has an opening at one end for blowing air into it and openings along its length for directing the air into the measuring head. A check valve is located in the flow passage so that air exhaled into the opening in the end of the mouthpiece can flow to the measuring head, but inhaling on the mouthpiece places the check valve in a closed position. The mouthpiece can be formed of a single molded piece or two tubular portions secured together. The end of the mouthpiece opposite the open end is closed and is spaced from the openings into the measuring head for forming a moisture chamber for collecting saliva.Type: GrantFiled: April 30, 1979Date of Patent: June 23, 1981Assignee: Sachs-Systemtechnik GMbHInventors: Dieter Lutz, Peter Krause, Axel Terveen, Volker Eibl

Patent number: 4268187Abstract: The present spreading apparatus for road construction mixtures, such as bituminous cold mixtures, has at least two V- or U-shaped screeding structures or screeds one leading and the other trailing with respect to the working direction. The leading screed extends tandemly, partially into the angle formed by the trailing screed. The leading screed structure has a worm type conveyor connected parallel to each wall of the V- or U-shaped screed. The worm type conveyor assures the homogenity of the road construction mixture and reduces the inherent pressure of the mixture against the leveling elements. Both the leading and the trailing screed are adjustably inclined away from the working direction. The adjustment of the screed position may be made, for example, by a spindle with a hand wheel.Type: GrantFiled: October 27, 1978Date of Patent: May 19, 1981Inventors: Ulrich Krause, Peter Krause

Patent number: 4222733Abstract: This invention relates to improved flow control mechanism for valve gated injection molding. The mechanism is of the type where movement of the valve pin is controlled by a pneumatically driven rocker arm. The back plate is cast with an integral pivot pin portion projecting from it and a pivot ball is fixed in a seat on the end of it. The rocker arm has a recess which receives the pivot ball for pivotal motion on the pivot pin portion of the back plate. The back plate is cast of a steel with sufficient strength and flexibility to withstand the repeated lateral loading on it due to the pivotal motion of the rocker arm, while the pivot ball is formed of a significantly harder material to avoid unacceptable wear where it is in moving contact with the rocker arm. Casting the back plate rather than machining it, enables bends in the runner passage extending through it to be smoothly curved, thus avoiding "dead spots".Type: GrantFiled: December 18, 1978Date of Patent: September 16, 1980Assignee: Mold-Masters LimitedInventors: Jobst U. Gellert, Peter Krause
