Patent EP-0306587-A2 (EP)
Inventor: DUDLEY KEVIN F
IPC: F24D17/02
Filed: 1987-12-23
Abstract: The integrated heat pump (10) and hot water system (32) includes a water to refrigerant heat exchanger (30) having a refrigerant evaporating circuit (42) and a refrigerant condensing circuit (41) that are in heat transfer relation with the water circuit (40). A bi-flow expansion valve (21) with a positive shut off feature is mounted in the refrigerant liquid line (20) connecting the indoor and outdoor coil (17,18) of the heat pump. The refrigerant evaporator circuit (42) is connected between the inlet of the compressor (12) and the liquid line (20) by an evaporator line (52) that enters the liquid line (20) between the bi-flow expansion valve (21) and the outdoor coil (17,18). A solenoid actuated metering valve (55) is placed in the evaporator line (52) to control the flow of refrigerant passing through the evaporator circuit (42). The condensing circuit (41) of the heat exchanger (30) is connected directly to the discharge line (13) of the compressor (12) so that the refrigerant discharged from the compressor (12) passes through the condensing circuit (41). By simply cycling the expansion valve (21) and the metering valve (55) a number of operational modes may be selected whether or not the heat pump (10) is con­ditioning comfort zone air.

Abstract: A system for formatting electronic binary image data, which may be in compressed raster form, into transposed or rotated raster form for storage or output, such as on a printing device, is disclosed wherein the image data is first assembled in a buffer in the form of vectors of run ends representing successive raster scan lines of an original image to be reproduced. The elements of an intermediate buffer are initialized to zero and the data is entered into the intermediate buffer by using each run end to set a bit in the intermediate buffer, with the bits being set in the buffer elements in correspondence with the respective raster positions of the run ends. The elements of the intermediate buffer containing the entered electronic data are then combined, such as by EXCLUSIVE-ORing, to create transposed or rotated raster data, which may stored or input to a suitable output device, such as a printer or display. The raster data may be compressed in the process and other processes, such as image reversal, may be carried out with facility.

Abstract: Disclosed is a method and circuit for reducing and maintaining constant overshoot in a high speed driver. The circuit includes a predriver circuit which is driven single endedly and a driver circuit which is differentially driven by the predriver outputs. The predriver and the driver are differen­tial pairs, with commonly controlled individual transistor current sources. A diode has been added in series with each emitter of the differential pairs. Schottky diodes are preferable because of their low capacitance. The diodes increase the input switching voltage (the smallest input voltage swing that will cause the outputs to fully switch) of the differential pair because they must also be switched on and off. The increase results in an increase in effective transition time, which results in smaller overshoots because the circuit is being switched slower. The output amplitude of the driver is set by a voltage which controls the current source currents of the commonly controlled current sources. As the amplitude is decreased the input switching voltage decreases because the current through the devices decreases which results in smaller base-emitter and diode voltages. Due to the commonly controlled current sources, the predriver amplitude decreases as the driver amplitude decreases. The predriver is designed such that its variable output supplies the driver with the proper input switching voltage at any driver amplitude. This keeps the effective input transition time constant which results in constant output overshoot.

Abstract: A digitized road network map can be stored in a location and navigation computer of the vehicle. Two nodes of the intermeshed road network form a route section, two guidance points form a sub-route with a separate address in each case. The travel time is measured using a travel time measuring device of the guidance and information device. The traffic congestion time contained in the travel time is calculated for each sub-route from the sum of all the time intervals during which the vehicle speed lies below a predetermined limit speed. In the location and navigation computer, the number of deceleration operations below the limit speed is measured for each sub-route and a weighting factor calculated therefrom. The respective weighting factors associated with the traffic congestion times are transmitted together with the latter to a central traffic and information controlling computer which evaluates the respective travel and traffic congestion time as a function of the size of the weighting factor. Using these evaluated travel times and traffic congestion times new alternative route recommendations are produced and evaluated for control of traffic light systems. <IMAGE>

Abstract: The present invention relates to a method and apparatus for separating gas by a pump from the medium being pumped, which method and apparatus are especially suitable in pumping the gaseous fiber supensions in the wood processing industry. In known apparatus, it has been difficult to prevent solids from entering the gas discharge system fur guiding the gas out of the pump so that the system would clog and give rise to the necessity for expensive and time-consuming reparation. 
     The method and apparatus in accordance with the present invention eliminates or minimizes the above disadvantages in that rear vanes (11) of the pump or the members operating together with them are arranged in such a way that they either direct the flow of the medium, generated by the combined effect of forces with different directions and different intensities directed at the medium in the space behind the impeller in the vane gaps of said rear vanes, past a gas discharge opening (12) in the rear wall of the pump, or they dampen the flow so that its extension to said gas discharge opening (12) is prevented.

Abstract: The thrust exerted on a drill bit (14) is sensed and employed to determine the speed at which the bit is driven. A controller (26) for the drill (10) compares the thrust to a predetermined threshold value and in response to the comparison emits a control signal which shifts a trans­mission (22) in the drill into high or low speed. After each shift, a number of thrust samples are taken in order to compute an average thrust for different strata (A, B, C) of the material (W) being drilled. At the completion of drilling each hole, the average thrusts for the hole are used to recalibrate the shift threshold value. In this manner, the shift threshold is adjusted to compen­sate for drill bit wear. The sensed thrust is also compared to a bit reject threshold value to determine when the bit is too dull for proper drilling.
