Abstract: PREFERENTIAL SIGNAL PRODUCTION ON A TEST STRIP IN IMMUNOASSAYS     ABSTRACT OF THE DISCLOSURE       An assay method and compositions are provided for determining the presence of an analyte in a sample.  The analyte is a member of an immunological pair (mip) of immunogens--ligand and receptor.  The method has two basic elements:  a solid surface to which one of the members of the immunological pair is bonded and a signal producing system, which includes a catalytic member bonded to a mip, which signal producing system results in a measurable signal on said solid surface related to the amount of analyte in the medium.  The signal generating compound is produced without separation of the catalyst labeled mip bound to the solid surface from the catalyst labeled mip free in solution.          In a preferred embodiment, an enzyme is bonded to a mip which acts in conjunction with a solute to produce a signal generating product which binds preferentially to the solid surface when the enzyme is bound to the surface, resulting in-a signal which is readily differentiated from signal generating compound produced by the catalyst and solute in the bulk solution.

Abstract: RCA 75,143 ABSTRACT           A video signal channel in a television receiver includes a keyed filter, followed by a keyed automatic brightness control circuit for establishing a desired black or blanking level for the video signal.  The brightness control circuit operates during blanking intervals of the video signal to sense the blanking level of the video signal for deriving a control signal which is utilized to maintain a desired blanking level.  The filter comprises a high-pass filter circuit which is decoupled for filtering purposes during image interals, but is coupled to the video channel during the blanking intervals for suppressing high frequency signals including noise, when present, in the video channel during the blanking intervals.  The sensed blanking level and the control voltage are therefore unaffected by noise components which would otherwise impair the control signal and thereby the operation of the brightness control circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to an electronic control system for wheel axles on rail-mounted vehicles, especially railroad car sets.  According to the invention, an accelerometer is attached on the bearing box for each axle end in all cars.  Each accelero-meter senses at running vehicle the vibrations of the bearing box and emits a corresponding electric signal to a signal process-ing unit common to all accelerometers on the same vehicle. Each such unit is capable on the basis of the different frequencies caused by wheel and bearing faults to distinguish individual fault signals and their origin in the car.  Information on the type of fault and on the axle, on which the fault is located, is passed to a fault indicating unit on the locomotive.  By means of an addressing arrangement via the signal processing units connected in series on the different cars, also the car is indicated, on which the fault is located.

Abstract: Abstract of the Disclosure In the manufacture of cells, e.g. of the system Li-Al/LiCl-KCl/FeSx, the finely divided raw materials for the electrodes and for an included ceramic separator are respectively mixed individually with the electrolyte salt, as well as with a synthetic plastic which is decomposable without residue under heat.  The mixtures are rolled into plates, and the plates are heated above the decomposition temperature of the plastic after assembly.  The plastic is preferably a polyhydrocarbon such as polyisobutylene and is preferably introduced by means of a solvent.  It makes the powder mixtures plastifiable and suitable for rolling.  This makes it possible to produce ceramic separators, which are fundamentally composed only of loose particle accumula-tions, in the form of plates of uniform structure and strength and to handle these in the same way as electrode plates during cell assembly.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a capacitive voltage divider drive circuit for electro-luminescent matrix displays comprised of, for example, thin film electrolumi-nescent capacitance type elements.  The drive circuit for each display element, which exhibits a relatively low capacitance, includes a relatively large series connected capacitor which couples a drive voltage thereacross upon the closure of a first switching element.  Due to voltage divider action, a relatively greater portion of the drive voltage appears across and energizes the display element by exceeding its threshold voltage.  Additionally, another relatively large capacitor is coupled in parallel with the display element upon the closure of a second switching element which, again due to voltage divider action, reduces the drive voltage thereacross below its energizing threshold level to deenergize it.  The switching elements are comprised of semiconductor switch devices which are adapted to operate in timed relationship with a resonant AC drive voltage applied to the matrix.  A plurality of row and column electrodes form the capacitive type display elements.  Moreover, each row electrode in the matrix is connected to a respective first switching element while each column electrode is connected to a respective series capacitor as well as a respective parallel capacitor and second switching element.

Abstract: ABSTRACT OF THE DISCLAIMER     A bottle rack for compactly storing and dis-playing   narrow-neck   bottles   in   an   easily accessible  manner.   An  upright  panel  has  a plurality  of  holes  passing  therethrough.  The holes are sized to receive the neck of a bottle inserted therein.  Below each hole is a pair of spaced-apart support pegs that transversely pro-trude out  from the panel so as to support the weight of the bottle. The support pegs are spaced apart a distance less than the body diameter of the smallest bottle to be stored or displayed in the  rack.  The holes  are  spaced apart  approxi-mately the same distance as the largest diameter of the bottle bodies. The holes are also arranged in a desired pattern, such as rows and columns, so that the bottles may be stored in an orderly fashion. In one embodiment, the support pegs pro-trude  out  from  both  sides  of  the  panel  and, accordingly,  bottles  may be  inserted  into  the rack from either side of the panel. The support pegs prevent undesirable lateral movement of the bottles and also allow sufficient visibility to enable  the  bottle  labels  to  be  easily  read. Support structure is used to hold the panel in its  upright,  generally  vertical,  position.  A cabinet  may  be  built  around  the  panel  having doors that allow access into the rack area from either side of the panel.

Abstract: ABSTRACT           A clock rate generator is described which can be programmed to provide an output clock that is N/M times the rate of a standard clock where N and M are integers.  The generator comprises a counter, a programmable memory, reset logic and a clocking control.  A standard clock is applied to the counter so that the counter is advanced by one for each clock bit.  The output of the counter is connected to the input lines of the programmable memory where a pattern of binary ones and zeros are stored.  The output of the programmable memory is applied to the clocking control to combine successive bits of the same polarity.  The divisor M is determined by the number of standard clock counts between successive resets of the counter.  The multiplier N is determined by the number of output cycles from the clocking control between successive resets of the counter.
