Abstract: ABSTRACT:         In a matrix of diplay elements arranged in rows and columns with row scanning and column selection  all dis-play elements which are connected to a scanned row conductor are always ignited, such that the non-selected display ele-ments of that row receive a low quiescent current through quiescent current supply circuits in the column selection circuits and the selected display elements a higher display current through selection circuits in the column selection circuits.         The low quiescent currents reduce the ignition-voltage for the next following row to be scanned whilst yet a high contrast is produced between the selected and non-selected display elements.

Abstract: MATERIAL FLOW MONITORING CIRCUIT     ABSTRACT     An electrical circuit assembly is provided for monitoring the flow of particulate fuel material in a chute having window areas on opposite sides thereof.  The circuit assembly emits a light at one window end of the chute which is received at the opposite window end of the chute by a circuit assembly.  The condition of the received light is dependent upon fuel material flow in the chute.  If the flow is normal the emitted light will be intermittently interrupted by the particulate material resulting in chopped light being received by the circuit.  If the chute is blocked downstream the chute will be filled with material and there will be no light received by the circuit.          Similarly, if the blockage is upstream the chute will be empty and an uninterrupted light will be received.  The circuit analyzes these received light conditions and produces output signals indicative of the mentioned fuel flow conditions.

Abstract: CYCLONE SEPARATOR VORTEX FINDER COMPLEX WITH                 EXTERIOR HEAT FINS          Abstract:       A cylcone separator having heat dissipating and structural re-enforcing means.  The cyclone separator has a gas outlet tube passing through the top of the separator shell and extending into the cyclone body.  In order to prevent high temperature build-up the connection of the outlet gas tube with the shell is specially designed in order  that heat contact be with only one side of the out-let gas tube wall.  The gas outlet tube has a lower port-ion extending into the top portion of the separator shell and is connected to an inverted frusto-conical upwardly diverging wall.  This wall is also connected to the top wall of the cyclone separator.  This structure provides an annular space to dissipate heat from high temperature gases which would otherwise in conventional structures contact both sides of the wall of the gas outlet tube and break down or liquify the metallic structure.  Radial heat transfer fins are preferably employed within the annular space connecting the exterior gas outlet tube to the diverging wall and the top of the cyclone separator for additional heat transfer and dissipation to the outside atmosphere and also as a strengthening means.  The inter-ior walls are insulated with conventional ceramic or refractory material to minimize heat losses.

Abstract: SYSTEM FOR TRANSMITTER FREQUENCY CONTROL           IN COHERENT LADAR ABSTRACT OF THE DISCLOSURE         A system for ensuring that the transmitted pulse of a coherent ladar is at the correct frequency for coherent detection of received echoes.  A hybrid laser transmitter has its continuous mode signal frequency swept through the stabilized frequency of a local oscillator laser.   At the instant when the frequency of the transmitter is at a predetermined difference with the frequency of the local oscillator, a high powered output signal is pulsed in the hybrid laser.  The resulting reflected, received signals can be mixed with the continuous local oscillator signal in a crystal mixer to produce pulses at the intermediate frequency for amplification and detection.  The effect of random variation in frequency of both the local oscillator and hybrid laser is thus avoided.

Abstract: ABSTRACT    This invention provides a valve by means of which a major portion of the suction flow of a swimming pool filtration system is channeled through an automatic cleaning device which cleans the floor and/or wall of a swimming pool, and a minor portion of the suction flow is drawn from the surface of the pool thereby to skim the surface.  The valve has a main inlet opening connectable to the device, an outlet opening connectable to the filtration system and an auxiliary opening which is closed to some extent by a closure member to normally provide a restricted aperture through which the water drawn from the surface flows.  The closure member is biassed closed by a spring located in a variable volume chamber which communicates with the interior of the valve between the auxiliary opening and the main inlet opening.  When the restricted aperture is blocked by leaves or the like, the pressure in the chamber decreases, compressing the spring and allowing the closure member to open.  The leaves or the like then pass through and the closure member closes again.

Abstract: A B S T R A C T       A system for multiplexing or demultiplexing pulsed. laser radiation having an acousto-optical device which is electrically controlled to switch a common path of high pulse rate laser radiation between a plurality of spatially distinct paths of relatively lower pulse rate laser radiation at which the pulses are sequenced according to a predetermined time pattern.  The acousto-optical element typically includes a Bragg cell which is electrically driven by a set of distinct frequencies, causing deflection of radiation passing therethrough at a predetermined set of angles whereby pulsed radiation of a single path may be distributed onto the plural separate paths or radiation on plural separate paths of time-sequenced pulses of radiation can be combined into a single path of augmented pulse rate.  The control of the acousto-optical element may be provided by selectively switching the output of a plurality of fixed frequency oscillators of different frequency to the acousto-optical element in accordance with the pattern of pulses on the common or plural distinct paths or a voltage-controlled oscillator may be sequenced through a repeating set of frequencies which are sampled one or more times per sequence to develop an error signal resulting in feedback control over the oscillator to eliminate long-term drift.

Abstract: ABSTRACT The present invention relates to a device for detecting breaks or tears which occur in a strip of any sheet-like material while the sheet slides and advances on rollers in a fixed or variable direction.  The detect-ing devices normally use photocells which are predisposed for detection of the lack of paper or the like, and the subsequent control for the junction or splicing.  One shortcoming which arises is that in many cases the strip may tear laterally, and since the tear does not take place completely along the entire width of the strip, it is not detected by the photocell.  In such cases the known detecting devices very frequently will not give, when it is most necessary, the control for the junction which is desired, thereby necessitating the manual intervention of an operator and reducing the operating efficiency of a production line.  The present invention provides a detecting device for tears and breaks for detecting the end of the strip.          This eliminates the above-mentioned inconveniences and puts the joining machine in condition to operate at full speed without the intervention of an operator.  This is accomplished by providing a fixed support, on which a device for detecting the tear and the end of the reel, along with a sensor provided with a blade can slide and be positioned in the direction of the width of the sheet which is sliding and advancing.
