Abstract: A press for making pressed board has a plurality of longitudinally spaced rigid frames, a lower press plate extending longitudinally through and secured to the frames, and a normally planar upper press plate extending longitudinally above the lower plate through the frames and defining with the lower press plate a longitudinally throughgoing press gap.  A plurality of vertically effective double-acting hydraulic cylinders carried on the frames above the upper plate each have a back compartment and a front compartment, are connected to the upper plate, and support the upper plate on the frames.  Respective upper and lower endless belts have respective lower and upper stretches extending through the gap immediately below and above the respective upper and lower plates and respective upper and lower rollers advance the stretches longitudinally through the frames.  Sensors connected to the lower plate produce an output corresponding to the size of the gap.  A safety unit connected to the upper plate produces an output when the upper plate is deformed to a predetermined extent from a planar shape.  A hydraulic valve system connected to the compartments of the double-acting cylinders pressurizes and depressurizes same.  A controller connected to the safety unit and valve system pressurizes the front compartments of the cylinders when the safety unit generates its output and thereby hydraulically blocks downward movement of the upper plate.  This arrangement obviates the use of mechanical stops for preventing contact of the press plates with each other. When the upper plate is deformed excessively, movement thereof is blocked hydraulically. The system is more flexible and adaptable to various working conditions.

Abstract: A gear device is disclosed, such as a change gear transmission of the countershaft (21) type in which, mounted for rotation about the countershaft is a larger gear (17) and a smaller gear (29). The transmission housing (11) defines a first lubricant reservoir (R1), having a nominal fill level (L1), which is able to lubricate the smaller gear as it rotates. A partition member (51) is disposed around the larger gear and defines a second lubricant reservoir (R2) through which the larger gear passes as it rotates. The partition member defines fluid passages (71,73) providing restricted communication from the first reservoir to the second reservoir. The fluid passages (71,73) are sized such that as the larger gear rotates, carrying lubricant out of the second reservoir (R2), there is maintained in the second reservoir a second fill level (L2), below the first fill level (L1) such that at least a portion of the teeth of the larger gear (17) pass just below the second fill level as the larger gear rotates. The result is substantially reduced churning losses, without decreasing the ability to lubricate the smaller gears.

Abstract: Known multi-phase electric machines have conductor lanes which do not sufficiently utilize the space available in the grooves and winding overhang or which are costly to produce. Besides a good utilization of the available space, the length of the conductors in the winding overhangs should be kept short in order to obtain high effiency and power densities, and the number of different conductor designs should be minimized in order to reduce production costs. According to the invention, the electric machine consists of several electric pole units which have each a small number of phases and poles with alternating polarity in the direction of displacement. The electric pole units are located next to each other in the air gap and are mutually offset by a fraction of a pole pitch with respect to the rotor poles. Their meandering rectangular conductor wires extend in layers parallel to the air gap. In monophase electric pole units, the conductor insulation is designed for only a fraction of the terminal voltage; by small increments a high effective conductor proportion is achieved. The modular design allows electric machines to be assembled from a few different structural shapes which, because of their simple design, may be produced on a large scale in a totally automated manner.

Title: Potentiometric biosensor and the method for its use
Inventor: KOST KENT M
IPC: G01N27/416
Filed: 1994-07-21
Granted: 2004-02-24
Abstract: A potentiometric biosensor, test strip, reagent, and a potentiometric method for detection or measurement of an analyte from a fluid sample. The biosensor includes indicating (3) and reference electrodes, (5), and a reagent (9), which overlays a portion of the surface of the indicating electrode (3). The reagent generally includes an enzyme and a redox mediator. When a fluid sample (e.g., blood) containing an analyte (e.g., glucose) is added to the reagent, the enzyme (e.g., glucose oxidase) catalyses a reaction involving enzyme, redox mediator (e.g., potassium ferricyanide), and analyze. This reaction may be monitored by monitoring the electrical potential at the indicating electrode surface. The inventive potentiometric biosensor measures the change in potential at the indicating electrode surface after the fluid sample containing the analyze is added to the reagent. The change in potential that occurs may be correlated to the detection or measurement of analyze in the fluid sample.
