Abstract: SORTING SYSTEM AND APPARATUS                 ABSTRACT OF THE DISCLOSURE Method and apparatus for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including potatoes, onions, tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. The objects to be sorted move along the zone supported from two positions for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience charac-teristics are rejected from the zone, while those exhibiting a lesser resilience are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. By adjustment of frequency of thesorting zone oscillatory surfaces, a multi-stage sorting system is made available.

Abstract: DIGITAL CARDIAC PACEMAKER          ABSTRACT       There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of cardiac stimulating pulses.  The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signal-ling the acceptance of a programming signal, and means to reset the program acceptance circuit if extraneous signals are detected as programming signals. The program signal acceptance circuit performs several different checks on the detected programming signal including a parity check, an access code check and determining if the proper number of signals were transmitted with-in a given time.  The timing circuit of the pulse generator includes a crystal clock oscillator and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.

Abstract: Abstract This invention is directed to a system for generating clock signals from a source signal having two har-monically related and phase coherent frequencies such as shown in U.S. Patent 3,534,344 (Santana) and U.S. Patent 3,879,753 (Dunn).  The clock system employs a pair of synchronous demodulators for generating a phase error signal to control a voltage controlled oscillator (VCO).  The source signal is applied to a pair of synchronous demodulators, each of which is supplied with a different carrier frequency.  The output of each demodulator represents the area of the signal being demodulated.  The output of each demodulator is zero and a null condition exists when the system is in a phase locked condition.  At a non-locked condition, the output of one demodulator has multiple null points. The function of the second demodulator is to resolve the ambiguity between the desired and undesired null points.  Carrier signals are generated under control of the VCO by dividing the output of the VCO signal to obtain carrier signals having the appropriate rela-tionship to the source signal.

Abstract: F.93 ONE-FOR-N MODEM CONTROL APPARATUS     ABSTRACT      Communications apparatus includes one-for-n modem redun-dancy for a plurality of typically contiguously disposed modem modules.  The modem modules comprise ? active units each illus-tratively operating in a different frequency band and a redundant (spare) modem of electronically adjustable frequency.  The on-line (active) modem modules each include a multiplexer which normally connects user terminal equipment associated with the module to the frequency translating and data and control signal processing circuitry in the module.    When a fault is detected in one of the modems (sensed, for example, by negated module "data valid" or "clear to send" levels for receive and transmit modems, respectively), a hier-archal control network and related apparatus automatically sets the redundant modem to the proper operating frequency and sub-stitutes the spare for the failed unit via the appropriate multiplexer.    In an alternative, microprocessor controlled embodiment of the present invention, the dedicated priority of the hierarchal control network may be replaced by any desired algorithm for alloting the redundant modem among the ? on-line unit.

Abstract: ABSTRACT OF THE DISCLOSURE          The metering apparatus for small volumes of liquid in the milliliter and microliter range comprises a piston/ cylinder system driven by a direct-current motor.  The piston stroke is measured by means of an optical path-length measur-ing system.  For this purpose, a slide-rule pulse scale pro-vided with a regular line grid is affixed to the piston.  The light from a light transmitter passes through the slide-rule pulse scale and a stationary scanning plate which likewise is provided with a regular line grid, and to a light receiver.          The pulses of the light receiver are digitalized in a pulse conditioning circuit and fed to a  counter adapted to be pre-set by means of a coding switch.  The counter position acts upon a braking and rotative-speed regulating circuit in such a way that regardless of the preset desired value of the rotative speed the speed of rotation of the motor is reduced to a small value as the final value of the counter is approached.  As soon as the preset volume has been metered and the counter has reached the corresponding position, the motor is brought to a dead stop through a motor-control logic circuit with the aid of a reverse voltage.  During the stopping process the no-load voltage of the motor is measured by means of a zero-voltage comparator at regular intervals.  A pulse monitoring circuit serves to measure and regulate the piston-stroke speed and to turn off the motor in case of a mechanical defect.          Motor and electronic systems are supplied with current from dry cells or storage batteries, a power supply being optionally provided to charge them.
