Abstract: ABSTRACT         The invention relates to new azolylpropyloximino derivatives, to several processes for their preparation and to their use as fungicides and plant growth regulators.         The compounds of the general formula                  (I) ln which A, R1 and R2 have the meaning given in the descrip-tion, are obtained if azolyl-ketones are reacted with substitu-ted hydroxylamines, in the presence of a diluent:  in addition, there are also other processes.         The active compounds are suitable for use as plant protection agents, and can be employed with particularly good success for combating diseases of cereals and disea-ses of rice, and for combating bacteria.    In addition, the active compounds intervene in the metabolism of the plants and can be used as growth regulators.

Abstract: Abstract A flow distributor capable of forming a defining wall of a duct or chamber having further defining walls comprises a profiled, apertured plate. The plate is provided with profile sections or wall sections which extend transversally of the direction of the main flow immediately downstreams one or more apertures. The profile sections form baffle means for dividing the main flow of medium into a plurality of part flows and for deflecting said part flows through respective apertures to the opposite side of said defining wall.          Located between the profile sections are substantially planar, apertured sections which extend in parallel with or are inclined to the direction of the main flow, while forming an arrangement of step-like or shoulder-like protrusions. Alternatively, the plate may exhibit adjacent one or more of said apertures corrugations which curve inwardly or outwardly towards and away from said flow, a part of which corrugations forms said profile sections.

Abstract: INK JET PRINTING METHOD AND APPARATUS      Abstract of the Disclosure A method and apparatus for controlling the flow of ink in an ink jet printing system which includes an ink supply reservoir and an ink jet print head comprising an ink inlet, and ink outlet and an ink cavity between the inlet and outlet in fluid communication with a plurality of closely spaced orifices. Valve means are included in the ink inlet and ink outlet, and the valve means are both open to provide an operative mode in which the ink cavity is filled with pressurized ink and a stream of ink is produced from each of the orifices.  An idle mode is established periodically when printing is not desired by substantially simultaneously closing both valve means to interrupt the flow of pressurized ink through the print head.  The ink then in the print head drains until the surface tension forces at the orifices exceed the pressure within the head.  The result is a positive pressure within the print head which is sealed off with the result that no contaminant material is drawn into the print head.

Abstract: ABSTRACT         A Navigation system includes at least one pulse radar and a number of transponders which when receiving radar pulses transmit high frequency pulse modulated signals.          When receiving an interrogating signal from the pulse radar, the transponder transmits a response signal with a delay.          The delay is selected in such a manner that the response signal arrives at the pulse radar within a time space lying between the moment when all signal ethos, lying within a definite range, have been received and the moment when the next radar pulse begins.  The display scan in the radar is delayed by the same amount as the response signal.  In this way, the response signal competes with considerably weaker echo signals than in the case of a non delayed response.

Abstract: Abstract of the Disclosure An arbitration technique for controlling access to a bit-serial bus by multiple nodes in a data processing network.  Upon detection of no carrier on the bus, a node desiring access to the bus waits a predetermined number of quiet slots, each slot being a predetermined interval.  If that period elapses without another node's carrier being detected, the node desiring access is permitted to transmit.  For each node, two such delay interval possibilities are provided, one high slot count (and, hence, low priority) and one low slot count (and, hence, high priority).  The delay interval selection for a node is switched from time to time on a round-robin basis, so that all nodes get equal average priority.  The high value of the delay interval is N+M+1 slots, where N is the node number and M is the maximum number of nodes allowed on the bus; the low value is N+1 slots.  Initially, each node uses the former value.  Upon unsuccessful contention for the bus, the delay interval selection used next by the node depends on the number (LW) of the node which last won access to the bus.  Upon detecting a carrier while awaiting for access to the bus (i.e., losing arbitration to a higher priority node), the node which is waiting for the bus compares the number of the node (LW) which started transmitting with node number (N).  If LW was less than N, the node waiting for access uses a new waiting time of N+1 slots the next time the delay interval begins; if greater than the node number, the new delay interval value is N+M+1 slots.  Provision is made for a multiple path bus wherein much common receiver circuitry is used for the paths.  In that situation, if a node's receiver is busy on an alternate path when the node's delay interval expires, the node's delay interval is restarted with a waiting time of M slots assigned to the node.

Abstract: DIGITAL GENERATION of 3 PHASE PWM WAVEFORMS              FOR VARIABLE SPEED CONTROL OF INDUCTION MOTOR                  ABSTRACT OF THE DISLOSURE                Programmed digital equipment is utilized to generate three-phase pulse width modulated waveforms that are used in controlling an induction motor.  A microprocessor is programmed to initialize conditions in the system, to perform a main task including the storage of a converted analog signal, the checking of limits of motor motion and information fed back from from the motor concernings its position, and the ramping of frequencies to change the position of the motor.  A memory is provided for the programming which memory also contains tables that correspond to 90° of each desired wave form.   A single 90° segment  of each wave form is needed to generate all parts of each of the three phases.  An analog to digital converter is utilized to convert analog information concerning gain, set point, dead band and feedback signal into digital signals which are stored and processed by the microprocessor.  Programmable timers are connected to the microprocessors for generating the wave forms and for supplying master timing and interrupt signals indicative of an undesirable condition in the motor control.

Abstract: ABSTRACT    A  pleated  media  filter  element  is disclosed  which includes pleat spacers which are an integral structural part of the pleated media.  The construction of the pleat spacers is accomplished by scoring on the unfolded media a continuous line pattern upon the portion of the media which, when folded, forms a pleat tip of the element.  When the scored media is folded  into pleats  the patterns  each  define  areas  on  the respective pleat tips which are integral structural parts of the media itself.  The configuration of the pattern causes a portion of the media at the pleat tip to project transversely relative  to  the  respective  pleat,  serving  thereby  as  an integral spacer to space the pleat apart from the pleats on either side thereof.

Abstract: "PIPE BASE WELL SCREEN AND SYSTEM FOR JOINING A PLURALITY     OF WELL SCREEN SEGMENTS"                              ABSTRACT      Plural pipe-based well screen segments can be assembled more quickly and easily and with no chance of damage to the screen jacket by welding a boss ring to the center pipe of each segment intermediate the upper pipe end and the screen jacket and then using a slip to sup-port the boss ring.  The slip is designed to be supported by holes normally present in the master bushing of a rotary drilling table or platform and is of sufficient height that the screen sections can be joined without the operator having to bend over.  A pair of relatively light weight, hinged cantilevered plates can be easily lifted to pro-vide clearance for the screen jacket to be lowered through the table and are then moved to their horizontal position just before the boss ring portion of the screen is lowered so as to engage them.  A vertical bar on the slip acts as a wrench stop to permit the upper end of the pipe to be held stationary as the succeeding segment of screen is threaded to it.
