Abstract: An apparatus for programming an ECL PROM comprises conventional ECL row and column address circuits for selecting a particular fuse in the ECL PROM. The selection of a particular fuse in the ECL PROM generates a control signal in the address decoders corresponding thereto which enables a current drive gate and a current sink gate coupled thereto. A row program control circuit and a column program circuit are then enabled by an increase of potential applied thereto for turning on the current drive gate and the current sink gate coupled to the selected fuse. The turning on of the current drive gate and the current sink gate coupled to the selected fuse causes 50 to 100 milliamps to flow through the selected fuse, blowing the fuse.

Abstract: A centrifuge tube is used to hold a mixture of several constituents, and also contains a generally cylindrical float. The float settles, after centrifugation, into the zone occupied by the constituent whose volume is to be measured. The constituent layer will settle, after centrifugation, into the annular space between the tube bore and the outside of the float, and will be expanded axially due to the restricted volume of the annular space. The degree of expansion is dependent upon the respective sizes of the float O.D. and the tube bore ID, both of which must be closely controlled for accurate results. A known volume of a control material is placed in the tube to settle into the annular space during centrifugation in an area thereof outside of the constituent layer zone. The length of the band of the control material is measured after centrifugation and is compared to a known length which will result if the annular space is of the proper target volume. A correction factor is thus obtained and applied to all of the other constituent layers which were measured. The band thus forms a varying reference which reflects the actual volume of the annulus.

Abstract: A detuning/decoupling arrangement for a Magnetic Resonance Imaging (MRI) system quadrature RF coil arrangement (of the typing using the nuclear magnetic resonance, or NMR, phenomenon) uses switching diodes to selectively connect and disconnect portions of a segmented RF coil in response to a DC control signal. The DC control signal selectively forward biases and reverse biases the switching diodes. The DC control current flows through the RF coil itself, through the diodes, and then through the center conductor of a semi-rigid transmission line disposed in proximity to the RF coil. Because the DC current flowing through the transmission line is equal and opposite to the DC current flowing through the RF coil, the net magnetic field generated by the DC current flow is approximately zero -- eliminating artifacts in the MRI image that would otherwise be generated due to continuous DC current flowing whenever the coil is being used to transmit or receive RF.

Abstract: In most of the flue gas denitrification processes actually used in practice, ammonia is mixed into the flue gas stream. If excess ammonia is fed in to obtain a high degree of denitrification, the denitrified flue gas stream still contains residual gaseous ammonia. In addition, the entrained fly dust in most cases contains solid ammonium compounds which have been formed by reaction of the ammonia with acidic flue gas constituents. 
<??>As is known per se, the gaseous ammonia is scrubbed out of the flue gas and recovered. Ammonia is likewise recovered from the fly ash by thermal treatment or extraction. The recovered ammonia is fed in aqueous solution into a stock of aqueous ammonia. The ammonia used for denitrification is taken from this device and mixed as an aqueous solution into the flue gas stream.

Abstract: In a disc concentrator used for the dehydration of suspensions, with axially spaced suspension chambers and filtrate chambers which are open towards a stationary trough and are mutually separated by rotatable screen filter discs, the individual filtrate chambers are divided by radially and axially extending transverse walls into individual filtrate chamber sections which are distributed around the periphery and preferably sealed from one another. In addition, the filtrate outlet on the bottom side of each filtrate chamber is divided into at least two mutually separate filtrate outlet sections on the outlet side, which are arranged one after the other in the peripheral direction of the trough, for filtrate of varying purity. In conjunction with the individual outlet sections, the transverse walls ensure effective filtrate separation. In addition, the outlet sections can also be subjected to vacuum, in order to accelerate the dehydration process. <IMAGE>

Abstract: A graphics accelerator (91) responds to commands from a computer (86) in a graphic system by storing the definitions of non-uniform rational B-spline patches (12,13,14,15) and their associated trimming curves S₁-S₉). The graphics accelerator then produces device coordinates for trimmed polygons computed for each patch and sends these polygons to a display (94). Various improvements are incorporated to minimize the effects of roundoff error. The B-spline definitions of the trimming curves (27) in the uv parameter space of each patch are converted to approximating short straight line segments. Untrimmed polygon vertices, the end points of the straight line segments and the intersections of the straight line segments with subspan boundaries corresponding to polygon edges are kept in a data structure of linked lists of vertex tables (Fig 15). The data structure is traversed to determine new polygon vertices for trimmed polygons. The trimming mechanisms is compatible with recursive subdivision of patches to overcome practical limitations on the number of trimming curves that may be associated with each patch. The length of the straight line segments of the trimming curves is adjusted to compensate for less than ideal parameterization of the trimming curve functions. Associated with each trimming curve within a patch is information about the position of that trimming curve in the span. As each polygon for that patch is generated, those trimming curves that are clearly outside the clip limits for that polygon are excluded from consideration. This reduces the average number of trimming curves that must be processed for the patch, and increases the speed of the graphics accelerator.

Abstract: A pneumatic circuit pressure control device includes an electronic comparator (51,53) for comparing a transducer (19) generated pressure signal (41,49) from a pneumatic circuit (13) and a desired pressure signal (31,39) from a desired pressure input generator (21). The comparison circuit selectively actuates solenoid-­actuated valves (15,17) which control the pressure in the pneumatic circuit (13). Preferably, the solenoid (27) of the solenoid-actuated valve (17) produces an electromagnetic field for electromagnetic induction of a circuit (73) which oscillates the solenoid-actuated valve (17) to produce a variable orifice-like effect when small changes in pressure are demanded by the comparator circuit (51,53).

Abstract: A new class of calcium specific fluorescent indicator dyes having visible excitation and emission wavelengths combine at least one tricyclic chromophore with a tetracarboxylate parent CA2+ chelating compound having the octacoordinate pattern of liganding groups characteristic of BAPTA to give a rhodamine-like or fluorescein-like fluorophore. Binding of calcium 2+  increases the fluorescence of the new compounds by up to 40-fold. The calcium 2+  dissociation constants are in the range 0.37-2.3 microM, so that the new indicators give better resolution of high [CA 2+ ] levels than were previously obtainable with predecessor compounds such as quin-2 or fluo-2. The visible excitation wavelengths of the new compounds are more convenient for fluorescent microscopy and flow cytometry than the UV required by previous indicators.
