Granted: 1996-05-27
Abstract: A method of providing a circulating air flow in a treatment space for a working area, whereby inlet air (A) is blown into the treatment space (1) to form a circulating air flow (A') in the treatment space, which flow provides an air curtain (A'') at an access opening (5) to the treatment space. In order to eliminate the disturbing influence of a workpiece (4) within the working area (3) on the circulating flow and to improve the working conditions, at least a part (B) of the circulating air flow (A') is deflected from the working area in such a way that the working area remains essentially within the circulating air flow. An arrangement for carrying out the method comprises a duct (7) formed in the treatment space (1) and passing the working area (3) for at least a part (B) of the circulating air flow.

IPC: H04B10/00
Filed: 1978-11-17
Abstract: In the transmission of messages on lightwave conductors, upon the rupture of such lightwave conductors, dangerous rays can occur that cause eye damage. Therefore, an installation is proposed that, upon the rupture of a lightwave conductor, communicates this rupture to the transmitting station via an auxiliary or return line. This communication causes the transmitter to transmit only pulsed messages in the direction of the rupture location, so that the radiation occurring is harmless. Further, the installation sees to it that upon reception of the pulsed message in the receiver following the rupture location, a return notice is transmitted to the transmitter concerned, so that the transmitter is caused to again switch the full signal output through.

Title: Apparatus for detecting fluid line occlusion
Inventor: HORRES C RUSSELL
IPC: A61M5/168
Filed: 1990-11-01
Granted: 2000-04-18
Abstract: The apparatus and method for detecting pressure and occlusion in a fluid line is for use with a fluid line being operated upon Say a positive displacement, peristaltic pump having several cam follower fingers pressings against the fluid line sequentially to force fluid through the line peristaltically. A sensor follower finger is mounted to the cam shaft of the pump among the other peristaltic fingers in order to cyclicly press against the fluid line with a certain degree of force and displacement as the cam shaft rotates. The sensor follower finger includes a strain gauge mounted on the sensor finger to generate a signal indicating the degree of force being applied by the sensor finger against the tubing, and a signal processor unit which receives this force signal and determines the pressure within the fluid line used upon the signal. The signal processor compares the measured pressure with an upstream reference value during an upstream pressure measurement mode, and compares the measured pressure with a downstream reference value during a downstream pressure measurement mode. An alarm may also be provided for indicating if there is an occlusion condition either upstream or downstream when the measured pressure varies significantly from these reference values.

Filed: 1991-11-28
Granted: 2001-02-06
Abstract: To detect core-wide and regional neutron flux oscillations in a nuclear reactor core induced by thermal-hydraulic instabilities, local power range monitoring (LPRM) strings radially distributed throughout the core and having plural vertically spaced neutron flux detectors are locally assigned to individual oscillation power range monitoring (OPRM) cells radially distributed throughout the core.

Abstract: A motor vehicle signalling system for requesting a driver of a vehicle behind another vehicle to dim his bright lights.  The signalling system is low in cost, improves vehicle safety, promotes driver courtesy and is adaptable to all motor vehicle styles and models.  The signalling system comprises a flashing colored light mounted on the rear of the signalling vehicle and a control circuit for operating the flashing light.

The control system has three states, a normally off state, an operating state wherein the signal light flashes for a predetermined time, and an operating state wherein the signal light flashes continuously.  Alternate embodiments are disclosed wherein the signal light is automatically controlled and/or is located in a common housing with the vehicle's other lights.

Title: Clock recovery circuit with memory storage level comparison with high, medium and low thresholds
Inventor: SHIBUYA TORU
IPC: H04N1/41
Filed: 1992-03-27
Granted: 1997-10-07
Abstract: A coded image signal is received and stored into a first-in-first-out memory on a bit-parallel word basis and the storage level of the memory is compared with high, medium and low threshold values. A first positive trimming value is generated when the storage level is higher than the high threshold, a second positive trimming value when it lies between the high and medium thresholds, a first negative trimming value when it is lower than the low threshold, and a second negative trimming value when it lies between the low and medium thresholds. Differential sampling clock data is received and combined with each trimming value in an adder whose output is subtractively combined with a frequency variation of the line clock rate to produce a corrected differential sampling and line clock data. The latter is integrated to produce a frequency control signal that drives a voltage-controlled oscillator whose output is used to drive the memory for reading the coded image signal on a bit-parallel word basis.

Title: Baler belt arrangement
Inventor: GUNTHER DANIEL
IPC: A01F15/07
Filed: 1992-04-01
Granted: 1994-11-15
Abstract: A round baler has a baling chamber formed in part by a plurality of belts engaged with a plurality of rolls extending between opposite side walls of the baler, the rolls and belts being located such as to define an enclosed zone next to the baling chamber.  The belt arrangement is so designed that in conjunction with two rolls between which some of the belts extend directly there is used a roll arrangement which includes at least two axially aligned rolls offset from the other two rolls and being engaged by the remaining belts so that gaps are created between offset belts extending about the offset rolls and the non-offset belts extending directly between the first mentioned two rolls.  These gaps serve to permit pieces of the material being baled to escape from the area otherwise enclosed by the belts.  The offset rolls extend only over the width of the belts that run over them and are thus conducive for use with scrapers and/or augers which extend lengthwise of the offset rolls so as to prevent the material being baled from wrapping about the offset rolls.
