Abstract: A data processing system is disclosed which permits the use of a memory mapped floating point coprocessor or other such peripheral, by a process which is unable to ad­dress the peripheral's resident memory location but which is able to address a specified location. Memory mapping means intercept attempted accesses by the process to the specified location and diverts the process's access in­struction to cause it to access the corresponding mapped address instead. An illustrative implementation is also described, namely the use of a Weitek 1167 memory-mapped, floating point coprocessor by processes running in the "virtual mode" of an Intel 80386 CPU.

Abstract: In the lean-burn operation of spark ignition internal combustion engines, improvements in consumption and emission are obtained if the fuel is injected directly into the combustion chamber. Owing to large charge cycle control cross-sections, the space for installation of injection valve and spark plug is very limited and malfunctions in the combustion process occur owing to excessive gaps between injection valve and ignition device. 
<??>By the development of a fuel injection valve, which has wire electrodes on the injection side for forming a spark ignition device, the spark gap crossing in the area of the fuel introduced by the injection valve, optimum flame propagation conditions are obtained even for poorly flammable fuels or in the case of an extremely low proportion of fuel in the combustion chamber filling (stratified charge operation).

Abstract: A two-motor movement (11), in particular for a radio clock (10), in which, to correct the instantaneous display in accordance with the actual point in time, the passage of wheel apertures through the beam path (28, 34) of light barriers (27, 33) is detected, is to be designed to provide simpler conditions of assembly and a reduced energy requirement while providing more rapid possibilities for the correction of the display. For this purpose, the kinematically coupled second and minute wheels (18, 20) are driven by one motor (15) while the hour wheel (21) is driven in a manner kinematically independent of the said wheels by another stepping motor (24). Thus, rapid stepping on of the hour wheel (21) is possible without prejudicing the instantaneous position or stepping on of the second and minute wheel (18, 20). Because the positioning of the hour wheel (21) or of the hour hand moved by the latter does not require accuracy to one motor step, a simple reflex light barrier (28) can be used for position detection, with any desired mounting orientation of the hour wheel (21). On the other hand, the involvement of the third wheel (19) in a light barrier (34) leads to positioning or position detection of the minute wheel (20) accurate to one motor step. <IMAGE>

Abstract: A device controls in real time the assembly of data for a bit map scanning device such as a laser printer under supervisory control of a host processor. The image data words are stored in a source memory and assembled in a video buffer, and automatically scanned out to the scanning device. The host processor generates a simplified set of control words that defines graphics, text and layout of the page to be assembled. An arithmetic logic unit ALU takes care of address calculation for all interfaces. A barrel shifter provides for bit alignment of the image data words in the video memory. Also, background and color combination logic combines the fonts and graphics with background and texture information. A raster interface synchronizes the output of the assembled data with the scanning device. Three basic modes are supported: 1) dispatch mode, 2) font read/write mode, and 3) graphics load mode. The dispatch mode is the normal operational mode which provides for dispatching data from a source memory location to the video memory for supplying data from the video memory out to the raster printer. The font read/write mode, gives the host the ability to read/write font or graphics data from/to the source memory or the video memory. The graphics load mode provides for transfer of a bit-mapped window of data to the video memory. The video memory can be divided into two video bands. While one of the video bands is being read for supply   of output data to the scanning device, data in the second band is being filled with font and graphics information using dispatch. After scanning all data out of the first band, the apparatus switches to the second band for printing and refills the first band with new data using dispatch.

Abstract: A dopant film (21) contains an organic binder, an inorganic binder and a compound of an impurity element for diffusion. Both surfaces of the dopant film are coated with adhesive (22). Releasable sheets (23) sand­wich the dopant film. The dopant film permits automated alternate stacking with semiconductor wafers, providing an advantage of labor saving. When the alternate stack­ing is automated, it will become hard for the wafer breakage to occur, sharply decreasing the rate of break­age. Furthermore, since the adhesion of a semiconductor wafer improves, the variation in the diffusion depth will decrease.

Abstract: A method and apparatus for temporarily disabling an RCCB having a magnetically coupled sensing circuit, protecting an AC circuit, and the testing circuit described. The method of disabling the RCCB comprises: connecting a direct current power source to the circuit being protected by the RCCB, and injecting direct current from the direct current power source into the circuit protected by the RCCB, in order to magnetise the magnetically coupled sensing circuit of the RCCB, thereby desensitising the RCCB. The RCCB is rendered temporarily inoperative thus allowing a test to be made on the circuit. In the apparatus a current source (2) is connected to inject DC current into the RCCB in the protected circuit under the control of a ramping circuitry (3, 5). Once the magnetically coupled circuit of the RCCB is saturated a test of the AC circuit is carried out.

Abstract: Mixtures of liquids, which may contain dissolved and/or suspended substances, having different boiling points are separated by multi- stage evaporation, the evaporation stages being arranged in series and vapours from the evaporation stages being used for heating subsequent stages. To avoid spatial temperature inhomogeneities and energy losses, fresh preheated mixture is fed to the stage which is the second with respect to the direction of flow of the heating steam, the vapours from this stage being combined with the vent vapour from the same stage and being used for heating the subsequent stage, and the liquid phase, which is taken off from the second stage and contains less lower-boiling fraction, being fed to the stage which is the first in the direction of flow of the heating steam and whose vapours are combined, with compression, with fresh heating steam and used for heating the first two evaporation stages. In preferred equipment for carrying out this process, the first two evaporator stages (I,II) have a common heating steam space (19) and separate product spaces. <IMAGE>

Abstract: An automatic workpart centering mechanism for a magnetic or other chuck of a machine tool is provided. A computer microprocessor controls a digital air pressure regulator and/or an air solenoid valve to supply air pressure to a pneumatic centering hammer to control striking force on a workpart as it is rotated by the chuck and held thereon by a given chuck holding force with the location of the striking force on the workpart also under control of the microprocessor. The computer microprocessor maintains and up-dates a look-up table of striking force magnitude versus incremental workpart displacement magnitude from inputs received from preceding workparts centered on the chuck and interpolates from the table a striking force to be applied next to a workpart then on the chuck to effect movement of the axis of the workpart closer to the chuck rotational axis. The accuracy of the computer in estimating the optimum force for the next strike on a workpart then on the chuck improves as   the number of workparts centered on the chuck increases. Sensors are provided to sense the magnitude of incremental displacement of each workpart on the chuck resulting from each strike of the centering hammer and to sense the rotational cycles of the chuck such that the computer can determine the angular position of maximum workpart eccentricity relative to a reference marker on the chuck and can control the location at which the workpart is to be struck by the centering hammer. 
     Alternatively, the invention can be practiced by developing a chuck holding force magnitude versus incremental workpart displacement magnitude using a given, constant strike force for the multiple, successive centering blows delivered to each workpart

Abstract: In an exemplary embodiment, a test signal is sent by a base station at a suitable point in a communi­ications protocol. According to the evaluation of the test signal transmission, a relatively high data rate or a lower more conservative data rate is selected by a mobile unit for the transmission of a relatively lengthy data message. The test signal can be associated with a query from a mobile unit having a message to send, or with a contention polling message from the base. Such test signal can be transmitted at the lower data rate where its transmission characteristics (e.g. signal strength, jitter or quality of transmission of known information) can be used to predict probable feasibility of transmission at the higher data rate, but most preferably the test signal is part of a high data rate contention poll which may alternate with a low data rate contention poll.
