Abstract: The process is used to produce a detoxicating emulsion, in particular for ABC combat agents, in which the substances are mixed in accordance with a specified formulation and sprayed under pressure. The water is first sucked out of a water container 1 by a main pump 2 whose pressure side is again connected to the water container 1 via a short-circuit loop 4. A substream of water is then tapped off via a pipeline 5 and used for mixing with the substance C 8 (calcium hypochlorite). The mixture consisting of A 4 and an emulsifier are then fed via a metering pump 10 to the main pipeline 12 in accordance with a first mixing section 36 and in a second mixing section 37, the slurry consisting of water and C 8 is added to the main pipeline 12. While maintaining an adequate development time, possibly using an inliner 34, the emulsion is discharged via discharge lances 14. <IMAGE>

Abstract: Table lookup for an N  ×  N image on an M  ×  M 2D array is speeded by enhancing an address word to access table entries greater in number than the address word bit structure normally permits. This is done by organizing a 2D array (M  x  M) as a 8- interconnected array, decomposing the N  ×  N array into N/M  x  N/M subimages, and generating and enhancing dichotomy windows of size K  ×  K at the subimage level as table lookup addresses. For arbitrary combinations of M, N and K, the address word is broken into two dichotomies, and each dichotomy is altered by incrementing and decrementing. This provides multi-bit addressing for sufficient table entries to carry out in a single cycle the complex table lookup required for processing a multi-bit (i.e., 3  x  3) window. The output of a programmable logic array accesses four quadrants of memory. The current pixel number CPN is made available from the computer control. This is divided into two halves, HCPN AND LCPN, which are incremented or decremented to form signals IHCPN, ILCPN, DHCPN and DLCPN. Carry and borrow signals CIH and BDH, respectively, are concatenated with the other signals to provide the requisite number of table addresses. Address 00, for example, is HCPN when CIH=0. Addresses for the other memory banks are derived similarly.

Abstract: The invention relates to a method and an apparatus for mixing extinguishing water with a foaming or wetting agent in order to generate a water/foam mixture for fire-extinguishing purposes. In order for the suction jet pump to adjust automatically, within a predetermined range, to the differing throughputs and pressures at the consumer end, and hence to the changed circumstances, the cross- sections of the propulsion nozzle and the collecting nozzle are of variable design. In order that the quantity of foaming agent aspirated should also remain constant, a Venturi pipe is fitted upstream and/or downstream of the suction jet pump, its effective pressure being proportional and hence suitable for adapting the discharge cross- section of the foaming agent to the throughput of fire-extinguishing water. <IMAGE>

Abstract: The present invention is directed to a level sensitive diagnostic apparatus for a data processing component. The diagnostic apparatus requires only two free-running, non-overlapping clocks, and it may be controlled by software based enabling signals. In one embodiment of the present invention, each scan unit in a shift register chain comprises a plurality of level sensitive elements, e.g., data latches, which transfer signals from their input terminals to their output terminals in response to a "Phase B" pulse train. A multiplexer is connected to each data latch for commu­nicating run data to the input terminal of each data latch in a normal mode of operation. In test mode, the multiplexer communicates signals from the output terminal of one data latch to the input terminal of an adjacent data latch, so that the data latch signals are serially communicated through the resulting latch chain. The first latch in the series is connected to a test data input, and the last latch in the series is connected to a test data output. 
     In order to prevent the test data from propagating uncontrollably through the serially connec­ted latches, each multiplexer includes a test latch disposed between the test data input of the multiplexer and the output terminal of the preceding data latch in the chain. The test latch is controlled by a "Phase A" pulse train signal which is interleaved with but does not overlap the phase B pulse train, and each phase A positive pulse alternates with each phase B pulse. For controlling the multiplexers, a scan enable signal is connected to each multiplexer through a select latch for ensuring that the multiplexers operate   synchronously with the test data appearing on the multiplexer inputs. For maintaining the existing values at the output terminals of each data latch when desired, a FREEZE signal is connected to the enable terminal of each run data latch through a freeze latch.

Abstract: Particulate material is supported in a fluid medium by means of an ultrasonic standing wave while a reaction is effected or controlled involving the material so supported, for example with the fluid medium or other material contained in the medium. In a preferred arrangement, the standing wave is established by opposed ultrasonic transducers (304,305,306) producing convergent beams that compensate for attenuation of the ultrasonic energy in the fluid medium, and operating in the near field. The support provided by the standing wave is able to avoid settling of the particulate material in the medium and also agitates the material; both effects enhance the rate of chemical reaction and help to ensure that the particulate material is more uniformly exposed. The process has particular applications to biological reactions, such as fermentation, and to chromatography, as examples.

Abstract: A workpart chuck (10) has a centreing (52) member that is movable toward the axis of rotation (R) of the chuck as the chuck rotates the workpart (W) in an eccentric non-centred position. As the centreing member moves the workpart, a sensing device (100) senses the extent of changing eccentric movement of the workpart and generates an electrical signal indicative of the extent of such eccentric movement. The workpart is moved toward the chuck axis (R) until the signal reaches a predetermined value indicative that the workpart is rotating about its axis; i.e. the workpart axis (G) and chuck axis (R) are substantially coaxial. The centreing member (52) is offset slightly relative to the chuck axis of rotation to ensure that excessive movement of the centreing member placing the workpart centre (G) beyond the chuck axis of rotation will not result in the workpart being driven to an extremely eccentric position and possibly even off the face of the chuck (10). The sensing device (100) detects a sudden shift of the workpart position relative to the centreing member (52) indicative of such movement beyond centre, whereupon the control system (110) causes the centreing member to retract a small distance and advance in a new attempt to centre the workpart.
