Abstract: ABSTRACT OF THE DISCLOSURE           A high field capacitor structure includes an insulating layer having a carrier trapping region between two electrodes. The trapping region improves electric breakdown characteristics of the capacitor structure and is particularly useful in avoiding the low breakdown voltages and high leakage currents normally encountered in structures with asperities, such as SiO2 over poly Si.  The trapping region can be formed by chemical vapor deposition (CVD) process, by evaporation or by ion implantation.  The trapping region is close to the Si, but far enough away to eliminate the possibility of reverse tunneling from discharging the traps in the absence of an applied voltage.

Abstract: ABSTRACT OF THE DISCLOSURE         A power monitor including a high power shunt connected in series with an electrical load to develop a signal proportional to current which is then modulated.  A second signal proportional to the voltage across the load is developed by a voltage divider network.  The two signals are applied as inputs to an electronic multiplier which produces a modulated output signal which is proportional to the power being dissipated by the load.  The output signal from the mul-tiplier is fed through an isolation transformer which passes the modulated power signal, but blocks the high load voltage.          The power signal is then demodulated, filtered and displayed digitally on a meter.  This signal is also provided as an analog output.  An oscillator synchronizes both the demodulator and modulator, the oscillator drive of the modulator being iso-lated.  When the load is a three-phase device, two such watt-meter modules are employed to measure the current and voltages associated with two of the three legs of the load, the output of the demodulators of the two modules are then summed, passed through a filter and displayed as a single power reading.          During the summation process, the demodulated output signal is electrically scaled to read as horsepower, kilowatts, or percent of full scale.

Abstract: ABSTRACT OF THE DISCLOSURE           A gas turbine engine having a compressor and an air-cooled turbine is provided with a cooling system for decreas-ing the temperature of the turbine cooling air.  A compact heat exchanger, rotatable with the compressor, receives a portion of the pressurized air which is bled from the com-pressor.  Relatively cool engine lubrication oil is pumped through the heat exchanger into heat exchanger relation-ship with the pressurized air, thereby cooling the air and heating the lubrication oil.  The cooled air is then routed to and circulated through the turbine blades to provide improved internal cooling thereof.  The heated lubrication oil is collected from the heat exchanger and routed to a second heat exchanger wherein it is placed in heat exchange relationship with engine fuel to recover the heat extracted from the compressor bleed air and to return the heat to the engine operating cycle.  The cooling system is designed to contain the lubricant in the unlikely event of a leak de-veloping in the heat exchanger.  Incorporation of the heat exchanger of the present invention into a gas turbine engine permits a reduction in the quantity of compressor air required for turbine rotor blade cooling and, thus, provides an im-provement in engine performance.

Abstract: A METHOD AND APPARATUS FOR AUTOMATICALLY CONTROLLING      THE INCLINATION OF PATTERNS IN INK JET PRINTERS Abstract of the Disclosure An ink jet printer in which the nozzle for emitting a stream of ink drops, the charge electrode for charging ink drops in accordance with signals to be recorded, and the deflection electrodes for pro-viding an electric field therebetween to deflect ink drops in accordance with the magnitude of the charges on the drops, are mounted on a carrier which moves relative to an ink drop record receiving media for forming images indicative of the signals on the deflected ink drops. To compensate for the inclination of the image formed by the carrier movement relative to the recording media, a voltage gradient or difference is applied across at least one of the deflection electrodes so as to effect electric field distortion intermediate the electrodes to thereby compensate for the slant due to carrier motion.  The amount of distortion is controlled by monitoring the carrier velocity and automatically feeding back a signal to the distortion creating voltage difference to control the voltage difference dependent upon carrier velocity.

Abstract: ABSTRACT        An adaptable programmable calculator is provided by employing a modular read-write and read-only memory unit, a central processing unit, and an input-output control unit capable of bidirectionally transferring information between the memory or central processing units and a number of input and output units.  These input and output units include an alphanumeric keyboard input unit, a magnetic tape cassette reading and recording unit, an alphanumeric solid state output display unit, an output printer, an X-Y plotter, a magnetic or paper tape reading and recording unit, a magnetic disc reading and recording unit, and a modem for connecting the calculator via telephone lines to a remotely located computer.          The calculator employs an extended version of BASIC computer language and allows the user to enter a line comprising one or more alphanumeric statements into the calculator from the key-board input unit while visually observing an alphanumeric display of the line to check for errors therein.  Syntax errors are automatically detected by the calculator when an entered statement is terminated, and execution errors are automatically detected upon attempted execution of a statement or statements.          Both types of errors are indicated to the user via error messages displayed by the output display unit.  The calculator employs a compiler for converting each statement entered into the calculator in BASIC language into an internal stored format.         It also employs an uncompiler for regenerating in BASIC language any entered line converted to the internal stored format.  The magnetic tape cassette reading and recording unit employed in the calculator allows the user to chain together several pro-gram segments and allows program manipulation of several blocks of data on an individual basis.  An interrupt feature of the cassette unit facilitates searching for a particular file located on a magnetic tape at the same time the calculator is performing other functions.

Abstract: ABSTRACT      In order to ensure correct registration of printing, a printing device is provided with a transducer arrangement which scans the printing platen to detect one of the edges of the stationery or, in the case of continuous feed stationery, pre-printed markings on the stationery. The scanning may take place in the vertical and/or horizontal directions according to the direction in which precise registration is desired.  The transducer arrangement is provided with an associated light source and to avoid errors arising, e.g. from variations in ambient lighting level, the transducer arrangement comprises two sensors which are spaced apart in the direction of scanning and an associated circuit forms a difference signal from the outputs of the sensors, which is discriminated with respect to a predetermined threshold level to produce a signal representative of the edge or marking. In a second embodiment the sensors are spaced apart along a line which is inclined relative to the vertical and horizontal directions so that both vertical and horizontal registration may be achieved using only two sensors provided, of course, that vertical and horizontal movements of the stationery do not occur simultaneously.
