Abstract: A blood analysis system or instrument, generally, including an incubator station, a sample and reagent holding station, a pipette assembly, a centrifuge, an analysis station, and a transport assembly. Generally, the incubation station holds containers while reagents and fluids are being dispensed in those containers, and, if desired, for incubating the containers. The sample and reagent holding station holds samples and a plurality of reagents, and the pipette assembly transfers fluids from that sample and reagent holding station to containers in the incubation station. The centrifuge is provided for centrifuging the container, and the analysis station is provided to analyze the containers optically to identify reactions therein. The transport assembly carries the containers between the incubator station, the centrifuge, and the analysis station. Preferably, the pipette assembly is automatically operated to draw fluids and preselected reagents from the sample and reagent holding station, and to dispense fluids into the containers held in the incubation station to produce predetermined solutions therein. Also, the transport subassembly is automatically operated to carry containers from the incubator station to the centrifuge after the predetermined solutions have been produced in the containers, and then to carry the containers from the centrifuge to the analysis station.

Inventor: PIZAO MARCIO REGIS
IPC: F16K37/00
Filed: 1994-10-26
Granted: 2001-01-02
Abstract: A device (3) for indicating the operating state of a linear actuation valve (5) comprises a mounting plate (9) having a rectilinear slot (11) therein for slidably receiving a perpendicularly extending follower stem (6) fixed to a follower nut (4).

Abstract: In the operation of gas turbine engines, it is an ever increasing goal to reduce the amount of harmful elements contained within the emissions of the engine. In particular, it is of primary importance to reduce the amounts of nitrogen oxides contained within the emissions.  The use of a catalytic combustor is one known means by which the formation of nitrogen oxides may be controlled.  However, the use of a catalytic combustor in a gas turbine engine has been known to be effective primarily in the upper ranges of engine operation.  The present invention provides a combustor arrangement for a gas turbine engine that employs a first combustor means that utilizes a catalytic bed to react a mixture of fuel and air during an upper range of engine operation and a second combustor means that utilizes a plurality of premixed fuel injectors to ignite a mixture of fuel and air during a lower range of engine operation.

Title: Game apparatus and method for debugging game program
Inventor: NAKAJIMA TOMOHIKO
IPC: A63F13/95
Filed: 1996-12-19
Granted: 2001-03-06
Abstract: In a game apparatus and a method of debugging a game program, a base time is determined, then a start time of a debugging process in a game is set. Next, the base time is compared with the start time. If the base time is bigger than the start time, the start time of the debugging process in the game must be set again. In the game apparatus and the method of the present invention, therefore, the time in the game program is not inconsistent with the contents of a game history and the game program can be debugged correctly. Further, in developing a game program, debugging a game program does not waste working time and increase the work load of a developer.

Title: Thermostat with remote temperature sensors and incorporating a measured temperature feature for averaging ambient temperatures at selected sensors
Inventor: LAKIN BRIAN
IPC: G05D23/24
Filed: 1998-02-09
Granted: 2005-04-19
Abstract: A thermostat includes a first temperature sensor integral with the thermostat and at least one and typically three remotely positioned temperature sensors.      Switches are provided to select which one or more temperature sensors are employed to provide an averaged measured temperature. Voltages representative of the temperature ambient to each diversely placed sensor are applied to separate inputs to an analog multiplexer which transfers a single voltage to an analog-to-digital converter in accordance with address codes received from a processor. The output of the A-D converter, a digital count representative of the temperature measured by the currently selected sensor, is read by the processor and temporarily saved. Then, the next selected sensor is similarly processed. When all the selected sensors have been processed, the resulting counts are averaged, and the result is conventionally processed, as by passing it through a conversion algorithm, to obtain the averaged temperature which is employed as the measured temperature and compared against a current reference temperature to determine control signals to be sent to one or more environmental modification units such as a heater and/or an air conditioner.
