Abstract: Potassium hydroxide or another alkaline potassium compound is used to adjust the pH of an aqueous color developing clay coating composition in the manufacture of color developing material for use in pressure-sensitive or similar copying systems. This reduces the decline in reactivity with time of such material and increases initial print intensity compared with conventional material in which the corresponding sodium compound is used for pH adjustment. Especially good results are obtained where the material being coated is a paper of high acidity such as results from rosin/alum sizing.

Abstract: A gas turbine engine exhaust nozzle assembly having vertical thrust capability comprises a two-dimensional converging/diverging nozzle and a veer flap for forward thrust operation and a rotatable hood type deflector for vertical thrust operation, wherein the forward edge of the veer flap is attached to the downstream edge of the deflector hood. During forward thrust operation, the hood and rear edge of the divergent flap portion of the converging/diverging nozzle are moved synchronously to maintain the rear edge of the divergent flap portion and the front edge of the veer flap adjacent each other such that the veer flap is aligned with and acts as an extension of the divergent flap portion of the converging/diverging nozzle. Preferably, means are provided to independently trim the orientation of the veer flap to maximize thrust. A movable ventral flap defines the nozzle throat between itself and the deflector hood when the hood is deployed for vertical thrust.

Abstract: A high precision controller for an alternating-current multi-phase electrical motor that is subject to a large inertial load. The controller was developed for and is particularly suitable for controlling, in a neutron chopper system, a heavy spinning rotor that must be rotated in phase-locked synchronism with a reference pulse train that is representative of an ac power supply signal having a meandering line frequency. The controller includes a shaft revolution sensor which provides a feedback pulse train representative of the actual speed of the motor. An internal digital timing signal generator provides a reference signal which is compared with the feedback signal in a computing unit to provide a motor control signal. In the preferred embodiment, the motor control signal is a weighted linear sum of a speed error voltage, a phase error voltage, and a drift error voltage, each of which is computed anew with each revolution of the motor shaft. The stator windings of the motor are driven by two amplifiers which are provided with input signals having the proper quadrature relationship by an exciter unit consisting of a voltage controlled oscillator, a binary counter, a pair of readonly memories, and a pair of digital-to-analog converters.

Abstract: An improved input circuit for an electronic vehicle speed control unit is disclosed. An ignition current sensor coil is adapted to have a voltage differential signal induced therein each time an ignition pulse is generated by the vehicle engine. Electrical noise signals generated by the vehicle engine appear as common mode signals across the ignition current sensor coil. The ignition current sensor coil is connected at each end to a capacitor, both of which are connected to ground potential. The ends of the ignition current sensor coil are further connected to the inputs of a differential amplifier. The capacitors appear in a series loop with the ignition current sensor coil for the differential voltage signals and, consequently, provide tuning for inductance. However, the capacitors appear in parallel with one another to ground potential with respect to the common mode noise signals, thereby providing high frequency noise rejection for the input circuit. The differential amplifier further rejects the common mode noise signal applied to the inputs thereof.

Abstract: A motor-driven chain saw is electrically operated by means of a universal motor and has two brake systems operating independently of one another. A mechanical brake system serves as a safety brake and when actuated, the mechanical brake system brings the saw chain to a standstill instantaneously. The second brake system is an electric coasting brake, which when the switch is released stops the saw chain quickly but without recoil. The electrical braking is effected by reversing the polarity of one pole coil of the field winding and short-circuiting it with the rotor winding.
