Abstract: JET NOZZLE STRUCTURE FOR ELECTROHYDRODYNAMIC DROPLET    FORMATION AND INK JET PRINTING SYSTEM THEREWITH           Abstract of the Disclosure The practice of this disclosure obtains a monolithic structure use-ful for electrohydrodynamically synchronizing the formation of droplets in a jet stream exiting from a jet nozzle.  The monolithic structure is pri-marily adaptable for ink jet printing.  The jet nozzle structure provided by the practice of this disclosure includes a jet nozzle design in a crystalline semiconductor block, e.g., of silicon (Si), germanium (Ge) or gallium arsenide (GaAs), with an electrode structure which is inte-grally incorporated therewith whereby a variable electric field is established proximate to the orifice of the jet nozzle structure.  The electric field electrohydrodynamically perturbs the jet stream emitting from the jet nozzle structure so that formation of drops in the jet stream is controllably achieved, e.g. synchronously when the variable electric field is oscillating with a given periodicity.     In an exemplary practice of this disclosure, a conductive region is integrally incorporated with a jet nozzle design formed from a block or wafer or substrate of single crystalline silicon either in or on said noz-zle whereby a varying electric field is established proximate to the orifice such that the jet stream is temporally and spatially influenced electrohydrodynamically by said electric field.  For a particular design of the conductive region, a doped Si region in the Si substrate is utilized therefor.  In the fabrication of a particular type of jet nozzle design, which utilizes a block of single crystalline silicon during the fabrication of the jet nozzle, there is included a diffused p+ region and an insulation layer which is formed either unitary therewith, e.g., by oxidation, or is formed ancillary thereto by deposition of an insula-tion layer.  When a synchronizing signal is applied to said p+ silicon layer, an oscillating electric field is established proximate to the orifice of the jet nozzle.     There is achieved by the practice of this disclosure a monolithic device for ink jet printing with a plurality of jets which are controll-able either independently or cooperatively through appropriate integrated silicon semi-conductor circuitry.

Abstract: ABSTRACT OF THE INVENTION        A percentage of the grain lost is sampled constantly by sensors at locations across the rear of the sieve of a com-bine and the sound of the grain kernels striking the sensors is picked up by a microphone, amplified, filtered and fed to a ratio computing device which calculates the total grain loss from the sampling and displays same on a meter. A further sensor samples grain passing through the rear portion of a straw walker of a combine as this bears a direct relation-ship to the quantity of grain passing over the end of the walker.  It can therefore be used to calculate the grain loss over the end of the walker.  Once again the sound of the grain kernels striking the sensor is picked up by a microphone, amplified, filtered and fed to a ratio computing device which calculates the grain loss over the end of the walker and displays same on the meter.  A switching device enables the total of the grain losses to be calculated from the two sensors by means of a summation device to which both sensor signals are connected.  This switching device also enables the operator to weed out the grain loss over the sieve or the grain loss over the walker thus enabling him to determine where adjustments are required.

Abstract: ABSTRACT OF THE DISCLOSURE              A slide fastener includes a bottom end stop member for limiting the downward or opening movement of a slider along a pair of series of fastener elements carried on and along confronting longitudinal edges of oppositely disposed stringer tapes.  Each of upper and lower wings of the slider has a pair of guide flanges extending on and along its lateral edges.  The lengths of each pair of guide flanges are so related to the pitch of the fastener elements that those two opposed fastener elements, located within a guide channel of the slider in adjacent relationship to the front ends of the two pairs of guide flanges, have their respective longitudinal axes disposed downwardly of the front ends of the lateral guide flanges when the slider is in its lowermost position.  The invention provides advance in the art by achieving that with the slider in its lowermost position, the slider, a bottom end stop and fastener elements cooperate to prevent those two opposed fastener elements which are located within a Y-shaped slider guide channel from being forcibly disengaged from respective beaded tape edges even when a relatively severe lateral pull tending to separate the opposed stringer tapes away from each other is exerted on the fastener.
