Abstract: TWO-STAGE WEIGHTED CAPACITOR CIRCUIT FOR ANALOG-TO-DIGITAL AND DIGITAL-TO-ANALOG CONVERTERS     ABSTRACT OF THE DISCLOSURE    A two-stage weighted capacitor network for use as an analog-to-digital or digital-to-analog converter is described.  A capacitor ladder is included having two similar groups of capacitors connected in parallel.  In each group the parallel capacitors have values starting with value C and decreasing in binary fractional amounts C/21, C/22, C/23, C/24 etc. to C/2n-1.  The two groups are interconnected through a coupling capacitor of value C/2n-1 and each of the capacitors in the two groups are selectively connected through switches to either a reference voltage or ground potential. A high gain amplifier connected as an inverting amplifier with a 2C capacitor feedback path is connected to the capacitor ladder. When the circuit is used in a digital-to-analog converter, the 2C capacitor is reset and then the digital input pattern, consisting of 2n bits, is manifested by connecting the capacitor ladder switches to the ground potential for "1" bits and leaving the other swithces connected to the reference potential for "0" bits.  When the circuit is used in an analog-to-digital converter the output of the amplifier is connected to a comparator which serves as a polarity detector and which feeds a set of control logic.  The control logic then sets the switches, which were originally all connected to the analog voltage, in a binary search mode.

Abstract: ABSTRACT OF THE DISCLOSURE A focusing mechanism for a camera includes a drive arrangement for displacing the camera lens in accordance with the contents of a counter into which the output of a pulse generator is gated during a range pulse whose duration is directly related to the distance of a subject from the camera.  The pulse generator is programmed so that its pulse repetition rate matches the time-derivative of the function relating the subject distance to the lens position at which a subject is in focus.  Integration of the generator output is carried out by gating the generator pulses into a counter during the range pulse such that at the trailing edge of the range pulse, the contents of the counter will be the integral of the time-derivative evaluate between the limits of the range pulse, i.e., a definite integral representative of the lens position at which a subject will be in focus when located at a distance defined by the duration of the range pulse.  For fully automated operation as applied to a still camera, shutter actuation can be in response to arrival of the lens to the position at which the subject is in focus.  Applied to movie cameras, the lens can track a moving subject maintaining it in focus during filming.

Abstract: Title of the Invention INFRARED MOISTURE MEASURING APPARATUS               Abstract of the Disclosure Apparatus for determining the content of moisture or other substance in a material by measuring its relative reflectance at two infrared wavelengths.  A chopped radiation beam is produced by arranging a tuning fork such that an oscillating element alternatively moves first and second spaced optical bandpass filters having first and second passband wavelengths into position to intercept a beam of source radiation.  The chopped beam is directed on the material being analyzed, and radiation reflected therefrom is applied to a radiation detector.  The relative trans-mittance of the filters at their passband wavelengths are such that the radiation detector generates alternating pulses of equal amplitude for a material having a specified content of the substance.  The tuning fork also includes a third filter of zero transmittance which periodically interrupts the beam of source radiation so that the detector provides a background signal which is used to correct the amplitudes of the alternating pulses. The alternating pulses are separated and applied to a ratio-determining cir-cuit. The output from the detector is also applied a feed-back circuit regulating the temperature of the detector.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method and system for mixing gas with waste water in which the water is pumped through a plurality of mixing chambers into which the gas is injected at a step surface to form parallel streams of gas and water. An extending chamber contains the parallel streams as the interface between them becomes unstable, breaks down creating vortices and produces tiny bubbles which mix with the water. The extending chamber is tapered inwardly to permit opera-tion at higher air flow rates without blowing the bubble forming vortices out of the chamber.  Helical vanes are preferably provided in the bores which inject the air into the extending chamber to create better wave generating conditions to extend the range to greater air flow rates.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved cathode assembly for a gas discharge display panel is disclosed providing a first series of cathode elements in a first direction and a second series of cathode elements in a sec-ond direction.  A separate "keep-alive" element and "initiate sig-nal" element are also provided.  The keep-alive element maintains a localized source of ionized gas at all times.  Upon activation of the initiate signal element, the ionized gas moves from the keep-alive element to the initiate signal element.  The first di-rection elements are then sequentially activated to cause the ion-ized gas to pass from the initiate signal element sequentially to each of the first direction elements until the selected first di-rection element has been reached.  The second direction elements are then sequentially activated to cause the ionized gas to pass from the selected first direction cathode element to the second direction cathode elements in sequence until the selected second direction element has been reached.  As employed in a multi-layer display, when the ionized gas has reached the selected first-second coordinate on the cathode assembly, normal addressing of the anode and/or cathode elements within the gas discharge display panel can be initiated to cause the desired panel illumination to take place.          An insulated spacer defining channels is used in the cathode assem-bly to guide the gas discharge along the desired path, being so shaped as to prevent the ionized gas from moving out of the selec-ted first direction coordinate along the second direction cathode element.
