Abstract: ABSTRACT OF THE DISCLOSURE         An improved shipping carton is provided in which cups or similar containers being shipped therein impart stacking strength to the carton.  The carton has a rectangular shaped bottom wall, side and end walls connected thereto, top panels connected to the end walls, and flaps connected to the side walls and top panels.  Selected ones of the panels, walls, and flaps are adhesively secured together when the carton is erected.  The side wall flaps extend from the ends of the side walls only, so as not to interfere with the machine packing rows of containers in the carton adjacent and parallel to the sides of the side walls.  The top panels are flush with each other after the carton is erected, whereby no overlap of them occurs to interfere with stacking of the cartons.

Abstract: ABSTRACT:      A colour television system for transmitting a colour television signal, specifically for recording on and subsequently reproducing from a record carrier. The colour television signal to be transmitted contains a first carrier which is frequency-modulated with the luminance information and a second carrier which is modulated with the chrominance information, whose fre-quency lies between zero and the first-order lower side band of the modulated first carrier which corresponds to the highest modulation frequency.  Said second carrier does not have a fixed frequency, but is locked to the instantaneous frequency of the modulated first car-rier by a constant integral ratio.  Depending on the characteristics of the transmission medium and the signal processing equipment said ratio is preferably two or three.

Abstract: POSITIVE DISPLACEMENT PUMP     ABSTRACT OF THE DISCLOSURE           A variable volume, positive displacement pump apparatus for withdrawing samples of liquid from a reservoir and discharg-ing them into a sample analyzer.  In the preferred form of pump, two syringe assemblies are provided, each one having a movable plunger assembly and a valve unit associated therewith.  The plunger assemblies are reciprocated by engagement thereof by a motor driven, reciprocable carriage assembly which includes a cross member for pushing selected metering rods upwardly against the plungers.  The carriage also includes a pair of yokes to engage the plungers and pull them downwardly to aspirate the specimens.  Valve movement is achieved by a gear drive which moves the valve between one position which enables the syringe to be filled and another position enabling the syringe contents to be discharged.  The volume displaced with each stroke is determined by the length of the metering rod inserted between the carriage and the syringe plunger.  Selection of a desired length of metering rod is achieved by rotating a turntable containing plural rods so as to index a given rod of selected length into a position of engagement between the carriage and the plunger.  This enables rapid and highly accurate digital selection of pump volume to be made and provides the pump with outstanding accuracy.  Appropriate lost motion is provided in the mechanism so that, although  the carriage operates con-tinuously, the syringes are not moved during the time the valves are being positioned and vice versa.

Abstract: SUPERVISORY CONTROL SYSTEM           ABSTRACT      An automatic supervisory control system is arranged to provide monitoring and supervisory functions in a noisy electrical environment over communication channels which are also noisy and generally highly congested.  The system is designed to handle a large number of status monitoring stations which provide status signals, a relatively small number of display elements, memory elements for storing the status signals and control means for enabling the status stations, the memory elements and the display elements so that the large numbers of status signals can be stored, read out, and displayed in a relatively small number of display elements on a closed loop basis without destroying status signals until responsive action has been taken on the status signals.     The system includes a central control station linked to a plurality of status stations by a single dedicated or shared radio channel, a plurality of telephone wire lines, or a combination of both.  A coded signal is used to com-municate status signals and command signals between the central control station and the status stations.  The central control station includes the status display elements, the memory elements, an audible alarm indicator, printed status and command reports, a keyboard for data entry and a computer for controlling system operation.

Abstract: METHOD AND APPARATUS FOR MEASURING DISTANCE BETWEEN AN AIRCRAFT AND A GROUND STATION                        Abstract of the Disclosure A distance measuring system is provided including a ground station transponder continuously transmitting a repeating pseudorandom coded bit pattern, and at least one aircraft interro-gator receiving and locking onto the ground station signal.  The aircraft interrogator transmits a coded interrogation signal in precise synchronism with an arbitrarily selected any one of the repetitive code words (bit patterns) that comprise the repeating pseudorandom coded bit pattern which are coded identically with he interrogation signal and waits for a reply.  If the ground station receives the coded interrogation signal in synchronism with an identically coded word in its continuous transmission, it transmits a reply signal to the aircraft interrogator optionally encoded with synchronism error or interrogation steering informa-tion.  If no reply is received by the aircraft interrogator, it transmits its next coded interrogation signal shifted by one or more bits relative to the arbitrarily selected received code word from the ground station.  Successive interrogation signals are each shifted an additional predetermined number of bits until synchronism is attained and a reply signal is received.  The number of bits of shifting performed by the aircraft needed for synchronization when combined with the number of bits representing the whole code word intervals elapsing between transmission of an interrogation and receipt of a reply represents the distance be-tween the ground station and aircraft.  The optionally encoded synchronism error and steering information is respectively utilized by the aircraft to more precisely calculate distance and alter its time of interrogation.
