Abstract: ABSTRACT OF THE DISCLOSURE           In a channel selecting apparatus for a television receiver having a tuner with a voltage-controlled variable reactance device as its tuning element; digital codes representing or identifying respective channels are stored at respective addresses in a memory, and a digital-to-analog converter provides an analog control voltage for the variable reactance device in correspondence to each digital code selectively read out of the memory in a channel selecting mode of the apparatus.          Further, in a programming mode of the apparatus, the changing digitally coded counts of a counter which is counting sweep pulses are applied to the digital-to-analog converter for similarly controlling the variable reactance device and selected counts of the counter, for example, those which result in the appearance on the receiver screen of pictures or test patterns broadcast by selected television stations or channels, are written at selected addresses in the memory as the channel identifying digital codes.  Preferably, the digital-to-analog converter is constituted by a pulse-width modulator which produces a chain  of pulses at a constant repetition rate with the widths of such pulses being varied in dependence on the absence of coincidence between a circulating digital code and the digitally coded count from the counter as established either by read out of a channel identifying digital code from the memory or by counting of the sweep pulses, and the output of the modulator is passed through a low-pass filter to provide the analog control voltage in dependence on the modulated pulse width.

Abstract: TRACTOR MOUNTED SCRAPER BLADE                  ABSTRACT OF THE DISCLOSURE           A material handling assembly has a frame for attach-ment to the three point hitch of a tractor.  A laterally swing-able boom extends rearwardly from the frame and has an upright shaft at its rear end rotatable about an upright axis for sus-pending a reversible scraper blade whose angularity may be varied as the shaft is rotated.  The blade is releasably at-tached to and tiltable relative to the shaft.  All four func-tions of raising and lowering the frame, swinging the boom, varying the angularity of the blade and tilting the blade are hydraulically controlled.  A special four bar linkage coupled with the shaft provides for wide blade angularity adjustment. A fluid bypass arrangement interconnects the swing and angularity functions to accommodate for excessive loads which may be en-countered when the attitude of the blade is to be varied in accordance with desired grading operations.

Abstract: IMPROVED SEISMIC ARRAY            ABSTRACT OF THE DISCLOSURE          An improved seismic array is provided which has the capability to supply data to adjacent recording stations simultaneously.  The seismic array has a plurality of seismic detector connection points, and a seismic detector is located at each seismic detector connection point.  Dual weighting of the output of each seismic detector in the array is achieved by connecting dual resistors to the output of each seismic detector.  Two pairs of wires are also provided in the array, and one pair of wires interconnects one weighted output of each seismic detector to the first end of the array.  The second pair of wires interconnects the second weighted output to the second end of the array.          An amplifier is provided for use at either or both ends of the array, and a feedback network, including a resistor, is associated with the amplifier.  The ratio of the value of the resistance in the feedback network to the weighting resistor at the seismic detector determines the magnitude of the signal appearing at the output of the amplifier from the response of that seismic detector.  A Chebychev weighted array is achieved by a proper selection of resistor values.

Abstract: Système pour le soutirage et la transformation en puissance complexe de l'énergie électrique d'une ligne de transport à haute tension continue (HTCC), le système étant relié en série avec cette ligne de transport.  Le système comporte des extracteurs-convertisseurs de la haute tension continue en puissance active sous forme alternative ainsi qu'un ensemble générateur de puissance réactive relié à la ligne de transport et qui alimente à la fois les extracteurs-convertisseurs et la charge branchée sur la sortie du système.  De plus, il est prévu un dispositif de commande du taux d'extraction et de conversion de l'énergie HTCC en fonction de la puissance active fournie par l'ensemble générateur.  Ce dispositif de commande assure l'alimentation en puissance active par les seuls extracteurs-converti seurs.  A l'ensemble générateur est également associé un régulateur de tension qui a pour fonction de garder les tensions de sortie de cet ensemble générateur constantes, ce qui se traduit par une génération de puissance active nulle de la part de l'ensemble générateur.  Le système de soutirage est soumis à une tension de valeur proportionnelle à l'énergie soutirée de la ligne de transport alors que l'enceinte métallique qui le contient est à la tension de la ligne HTCC.

Abstract: ABSTRACT OF THE DISCLOSURE         There is described a method and apparatus for cleaning material from a support surface, such as an imaging surface of a photocopier.  The surface is moved in one direction relative to a cleaning blade that engages the surface.  There are rest periods of no relative motion between the blade and surface.  During these periods the blade is moved out of contact with the surface at a first position and is returned to engagement with the surface at a second position downstream of the first position.  The relative motion between the blade and surface may be reversed with the blade still in engagement with the surface prior to the rest period.  This reversal of relative motion tends to break up and remove the build up of material.

Abstract: U.S. 818,154 ABSTRACT OF THE DISCLOSURE       A  site stream monitoring device for a main unit such as a vessel, which effectively has the same geometrical and dynamic characteristics as those corresponding components in the vessel for enabling the side stream monitor to provide a ready indication ant continuous monitor of the performance characteristics and quality of the corresponding com-ponents in the vessel, upon removal and testing or examination of the device.  The apparatus and method for monitoring have particular utility in connection with clay filters or filter separators which are used for the removal of contaminants from e.g. jet fuels.  In each case a bypass side stream is disposed between the inlet lines of the filter or filter separator and located within the bypass line is a device which effectively is a reduced scale replica of a portion of the main unit which corresponds to the critical operating components thereof.          For the clay filter a duplication of flow velocities and residence times of the fuel through a predetermined section of one of the main filter elements is reproduced.  In the case of the filter separator, the side stream device comprises sections which are comprised of identical elements used in the main unit, including metal screens, fiber sheets, fiberglass screens, fiber sheets, fiberglass screens, etc., except that each component of the side stream monitor is of a reduced size ouch that the ratio of the cross-sectional area to the liquid flow is the same as that which exists in the main unit for that particular component.
