Inventor: HA JAE-KI
IPC: H05B6/66
Filed: 1999-11-03
Granted: 2002-11-12
Abstract: A microwave detecting device outputs a first predetermined voltage in accordance with the presence/absence of microwave in a waveguide. A microcomputer inputs the first predetermined voltage, outputs a second predetermined voltage in accordance with the level of the first predetermined voltage, then detects the voltage of an input port of the first predetermined voltage by applying the second predetermined voltage to the input port of the first predetermined voltage, and displays the operational status of the microwave detecting section through a display section in accordance with the voltage detected from the input port. The microwave detecting section includes a diode sensor, which is connected between the waveguide and the input port of the microcomputer in a forward direction to output the first predetermined voltage in accordance with the presence/absence of the microwave in the waveguide. The microcomputer may further include a check button for applying a check signal to the microcomputer, and then the microcomputer outputs the second predetermined voltage in accordance with the inputted check signal.

Title: Adaptive handoff hysteresis in wireless telecommunication networks
Inventor: BRINGBY DANIEL
IPC: H04W36/30
Filed: 1998-12-08
Granted: 2007-10-30
Abstract: A method of setting the appropriate hysteresis for cells in a wireless telecommunication network in order to reduce the rate of oscillating handoffs arising from a routine mobile station handoff from an originating cell to a neighboring cell. The method includes measuring the received signal strength in the originating cell and the received signal strength of at least one neighboring cell.  The hysteresis is calculated by applying a statistical operation, such as the standard deviation, to at least one of the received signal strengths. Alternatively, the hysteresis calculation may include the handoff oscillation rate. The calculated hysteresis value may be presented to the operator for manual adjustment or may be input into self-configuring cells for the dynamic adjustment of hysteresis levels to improve the network operating performance.

Abstract: The disclosed squaring device utilizes an upper squaring carriage (24) with compression belts (2) and pneumatically actuated squaring fingers (3). In on e embodiment, the upper squaring carriage (24) includes at least three compression belts. At least one of the compression belts, central to the oth er belts, is positioned to apply direct pressure to the glued seam after the upper panels and lower panels are aligned. As a folded box reaches the end o f the folding section and enters the squaring section, the moveable belt is raised so as not to apply pressure directly to the glued seam. The drive bel ts on either side of the seam maintain the box in compression. As the box approaches the squaring fingers, it passes a sensor that sends a signal to a programmable logic controller. At a selected time, depending on the conveyor belt speed, the controller actuates a pneumatic piston that drives a rack an d pinion mechanism to rotate the squaring fingers into position to intercept t he box travel. The bottom panel arrives at the fingers first, and is stopped by the fingers, and slips on the lower conveyor belt. The upper compression bel ts continue to drive the upper panels forward until they are also stopped by th e squaring fingers, bringing the box precisely square. The squaring fingers (3 ) are thenretracted, permitting the squared box to continue through the machine. In a second embodiment of the inventive device the upper squaring carriage includes two compression belts, with squaring fingers positioned outward of the belts, with respect to the center line of the conveyor. The embodiments share the feature that the belts are controlled to exert a lower pressure on the boxes during the squaring operation and a higher pressure on the boxes after they are brought into square.

Abstract: A rotor assembly for a rotary power device consists of two opposed rotor sections (42) which when assembled in the stator (10) are rotated by, or can rotate a drive shaft (23). Each rotor section includes through running cylinders (24) accommodating two piston heads (28) each, and a center passage for the drive shaft (23). Each rotor section defines inwardly extending support legs (46) and a rear face (48) which act to limit the travel of the rotor sections towards one another.  The base of the support legs (46) includes a socket (50) which is aligned with a socket in the rear face of the opposing rotor section. A  guide pin (52) and a spring (54) are disposed in the socket (50) of the support leg (46) and the guide pin (52) extends from the socket (50) into the rear face socket. The spring (54) acts to urge the rotor sections (42) away from one another so that the end walls of the rotor assembly are in contact with the end walls of the stator (10) of the rotary power device.

Title: Method for drying pasty materials
Inventor: KNOER PETER
IPC: F26B7/00
Filed: 2001-07-30
Granted: 2009-11-03
Abstract: According to the invention, on drying paste-like materials, in particular, clarifier sludge, the material is previously compacted to a dry weight in the range 60 80 % in a drying intermediate stag e, such that a relatively low energy requirement results. The transport of the material, both during the pre-drying and after leaving the compacting device (5), is by means of one or two transport belts (3, 4) which are arranged in series in the direction of transport, which permit the through-flow of air and which are enclosed in a common housing (2). As a result, the drying occurs under the same conditions before or after compacting, such that a plant for carrying out the above is easy and thus economical to install. The end product has advantageous properties with regard to density and friability, such that on subsequent handling the development of dust is avoided.

In an embodiment of the invention, the nozzle has a porous tip that extends into the invaded zone beyond the mudcake layer and is exposed to the formation pressure. In an alternate embodiment, the nozzle has a retractable tip that retracts into the nozzle. The nozzle and retractable tip are positioned in the mudcake and the retractable tip is retracted into the nozzle. The formation pressure is then communicated through the nozzle to a pressure sensor operatively connected to the nozzle.
