Abstract: MINIATURE INK JET NOZZLE                 ABSTRACT OF THE DISCLOSURE In an ink drop writing system a vibrating nozzle is used to form drops which are thereafter deflected electro-statically whereby characters or wave forms are written on paper by the deflected drops.  In order to minimize the variations in drive voltage requirements for the transducer that vibrates the nozzle, caused by changes in ink parameters which cause variations in the velocity of sound through the ink that is used, and in order to minimize variations in the drop separation time from the ink stream, with drive frequency variations, the length of the nozzle is selected so that its mechanical resonance frequency is very much higher than the frequency at which the nozzle is used.          As a result, the length of the nozzle is considerably shorter than the nozzle lengths which have been used heretofore.

Abstract: Abstract the Disclosure:        In apparatus for forming batches of cigarettes on a conveyor in which a divider plate is projected upwards into a stream on the conveyor a movable control plate is arranged in engagement with the upper surface of the stream in the region where the major part of the upward movement of the divider plate occurs.  This plate has an ironing action on the stream and helps control and prevent mis-alignment of the  uppermost cigarettes as the divider plate rises.  A principal use for batch-forming apparatus of this type is with tray filling devices which transfer cigarettes into trays by successively plunging batches from a conveyor.     ...  .    .    .    .

Abstract: VOLTAGE SENSING DEVICE FOR USE AT HIGH VOLTAGE           ABSTRACT:  A compact voltage sensing device for connection to an alternating current high voltage circuit is imbedded within an organic polymeric insulator body that is formed to provide both mechanism support and "line to ground" insulation for a conductor or component connected thereto.  The voltage sensing device comprises a capacitor and step-down transformer in series from the conductor to ground which provides a low voltage output which may be used to determine the magnitude of the voltage on the conductor, or as a source of control voltage for auxiliary apparatus.  The insulator body may be made to be equal in height and have the same mounting configuration as a conven-tional insulator so that it can be substituted for a conventional insulator in a distribution system.  The performance of the insulator body as insulation is not compromised by the presence of internal electrical components.

Abstract: DISK STORAGE APPARATUS HAVING SIGNALS          RECORDED IN A SPECIFIC FORMAT                     Abstract A record disk has a plurality of concentric record tracks divided into sectors of substantially equal lengths irrespective of the radius of the record track.  In a preferred form, the record tracks are banded into radial groups, with the circumferential length of sectors in the radially inwardmost record track being equal in all of the bands.  All track-identifying signals (servo signals) are radially aligned in each of the groups of tracks for providing sector servoing of a head to a given track.  In those embodiments employing a plurality of independently accessible disks, a tachometer is attached to the assembly with all of the disks being keyed to a tachome-ter index such that all locations on each of the disks have a specific format relationship to the key and the tachometer.  Each disk is separately calibrated such that its format has a calibratable relationship to the tachometer index.  Additionally, the specific format enhances radial positioning of a transducer for track selection.  In a more specific form, the outermost band of tracks has the greatest radial extent for access-ing stored data.  The specific format is particularly adaptable to those data processing apparatus employing fixed block length storage blocks.

Abstract: Abstract A burner for air-fuel mixtures, having a flameholder provided with closely spaced apertures and means for forcing an air-fuel mixture under pressure through the apertures of the flameholder, has an improved flameholder characterized by structure which produces, in successive zones of the flameholder, a. progressive inhibiting of the velocity of flow of the air-fuel mixture from the apertures in a waveform differential velocity, which diminishes from a maximum velocity region inter-mediate the zone to minimum velocity regions at either side of it.  In consequence, the mixture flowing through each zone at high flow rates and ignited forms a single flame of cor-responding waveform bridging the minimum velocity regions at each side of the zone, highest in the maximum velocity region and lowest in the minimum velocity regions, such wave-form flames being more stable and less noisy than individual flames opposite the individual apertures produced by uniform velocity of flow flameholders of the prior art.

A turn-over element is arranged in the path of travel of the upper corner of the blank, projecting beyond the removal element.  A gate is arranged in the path of travel of the turned-over corner of the foil blank taken over by the gripping element, the gate folding the turned-over corner through about 180° in relation to its initial position in the storage station.  The gate is followed by a pressure element for the folded corner.

Abstract: Abstract of the Disclosure The invention relates to an apparatus for dosing a liquid product into water, particularly for dosing a liquid detergent product into the water stream fed to domestic washing machines.  The apparatus is driven by the water pressure and therefore consists of two hydraulic pressure chambers into which the water is alternately directed.  In these chambers two rigidly connected pistons are moved.  The pistons are connected to the housing by membrane seals.  On one side of the apparatus a pumping part with a pumping chamber is located, into which one of the pistons can move.  The pumping chamber is provided with a non-return valve for sucking the liquid product from a reservoir and with another non-return valve for feeding the liquid product into the water stream in the common outlet pipe.  The pistons are connected to means for alternately directing the water stream to one of the two hydraulic pressure chambers. These means may comprise other means for counting, adjusting and limiting the number of strokes for one dosing operation.  Different amounts of liquid products can be dosed by predetermining the number of strokes.  Differences in the water pressure do not influence the quantities dosed.  Water can flow through the apparatus also before and after the dosing operation.
