Abstract: NOISE BLANKING SIGNAL GENERATOR FOR AM RADIO            Abstract of the Invention A noise blanking signal generator for an AM radio receiver includes a product detector adapted to receive an IF signal modulated by an AF signal and synchronously detect the AF signal, a first low pass filter adapted to derive from the product detector a filtered voltage indicating the average IF signal strength, a second low pass filter adapted to derive from the product detector an AF signal voltage and a reference voltage generating circuit ratiometrically related to the product detector through a common DC power supply and effective to generate a reference voltage substantially equal to the filtered voltage in the absence of an IF signal.  A voltage divider comprising a pair of resistors connected in series across the outputs of the first and second low pass filters has an output at the junction of the resistors, the resistors being of such ratio as to generate, when the AF signal equals a predetermined modulation level with reference to the IF signal strength, a voltage equal to the reference voltage at the voltage divider output, a comparator effective to compare the voltage at the output of the voltage divider with the reference voltage and generate a noise blanking signal when the former exceeds the latter and offset means effective to bias the comparator to not generate the noise blanking signal when the voltage at the output of the voltage generator does not exceed the reference voltage.

Abstract: METHOD OF AVOIDING STUCK DRILLING EQUIPMENT     Abstract A method of avoiding stuck drilling equip-ment during drilling of a well over depth intervals where such equipment has stuck in similar wells in a geological province.  A multiplicity of well drilling variable quantities are measured substantially simul-taneously at a known depth in each of a multiplicity of wells.  Such multiplicity of wells includes those in which drilling equipment has stuck due to mechani-cal problems or differential pressure between the drill string and an earth formation penetrated by the well bore, or both, and a multiplicity of similar wells where the drill string did not stick.  By multi-variate statistical analysis of all variables in all wells of each class, together with maximum separation of said classes from each other, a plotting plane for a currently drilling well relative to said classes is established.  The location of the relative position of all variables in such a drilling well with respect to the well classes is determined by summing the products of the coefficient of each variable for the complete group of wells times the current value of the var-iables in the drilling well.  The variables are then modified within allowable values to change the plotted location of the drilling well toward the mean of the wells that did not stick the drill string.

Abstract: Abstract A chassis for holding a plurality of printed circuit boards has a number of locations at which said printed circuit boards may be positioned.  Each of said locations having opposed slotted tracks for holding opposite edges of the printed circuit board placed at that location.  One of the locations holds a power supply for the chassis.    A printed circuit board retaining mechanism has a first position in which a tab extends across the slots in one of the tracks for each of the printed circuit board locations and a second position in which the tabs do not extend across the slot.  Each of the printed circuit boards has a notch along one edge.  When the printed circuit board is fully inserted into one of the locations in the chassis, the tab corresponding to that track engages the notch preventing the removal of the printed circuit board from the chassis.  The retaining mechanism also includes a switch actuator which engages a switch on the power supply so that when the retain-ing mechanism is in the second position, the power to the chassis is turned off.  This prevents the removal of one of the printed circuit boards while power is still being applied to it.

Abstract: A pix-in-pix display includes a filtering system for processing the video signals which produce the reduced-size image. The filtering system includes an anti-aliasing filter - (210) which reduces the amplitude of the components of the video signals which may cause aliasing distortion when the image is subsampled. However, the filter passes substantial amounts of these components. The filtered video signal is subsampled (212) and applied to a peaking filter (220) which amplifies the band of frequencies containing the aliasing components relative to lower frequency bands to improve the appearance of detailed portions of the reproduced image.

Abstract: An electromagnetic switching apparatus having a switch position indicator is disclosed. The switch position indicator is in functional connection with the contact carrier and protrudes beyond the cover of the switching apparatus in at least one switch position. The switch position indicator is coupled to the contact carrier by apparatus such that the switch position indicator travels a greater distance than the movable contact carrier in going from at least one switch position to another. Thereby, an unequivocal switch position indication can be obtained, particularly in an open contact condition which satisfies switch disconnect function conditions, thereby making the switching apparatus useful as a disconnect switch.

The carrier which, for example, may be a soluble macromolecule, e.g. cellulose or dextran, with ligand attached thereto, is utilized in dissolved form. The choice of ligand is determined by the type of peptide-containing compound for which it is to be used. Examples of ligands which may be used are immunoglobulins, Fc-receptors, certain surface receptors from bacteria, e.g. protein A from S. aureus, co-factors and certain sugar-containing proteins.
