Abstract: A B S T R A C T                 A PRESSURE TRANSDUCER     A differential pressure gauge    utilises a piston member    provided with a series of grooves    right around it, so that the piston member    itself forms the rack of a rack-and-pinion device for converting linear displacement of the piston member into rotary displacement of the pinion.  For sensitivity and accuracy, the seal between the piston member    and the passage    is a hard-surface-to-hard-surface engagement between substantial (total) hard surface areas at any one time of the passage    and the piston member including regions of the surface area of the piston member    intermediate mutually adjacent end ones of the grooves   .  In this way, the gauge is insensitive to the base pressure, there being no soft seals to deform under pressure.  A magnetic coupling is used through the wall of the housing, which can thus be made completely pressure-tight. One embodiment indicates a reverse differential pressure by allowing the piston to travel beyond the normal end position upon overcoming the preload of a second spring.

Abstract: Abstract of the Disclosure A method for operationally determining the existence of an optimal rapping interval for the collector electrodes of an electrostatic precipitator comprises the comparison of the current-voltage characteristics for precipitator operation under pure-gas conditions and actual use conditions. If the comparison indicates that the resistance of accumulated dust layers it greater than the resistance of air, then an optimal rapping interval exists.  This interval may be calculated analytically or approximated by means of an iterative process.

Abstract: Abstract Circuitry for decoding differential phase shift keyed signals utilizes a counter,  having a capacity selected such that in an integration interval having a duration equivalent to one-half the period of a reconstructed carrier, a full count and resultant rollover identifies a decision threshold for information descriptive of the received signal. At the conclusion of the integration interval, the contents of the counter represent half a full count thereof for no phase error in the reconstructed carrier.  Phase error in the carrier  is determined during  a  subsequent  interval  by counting up of the same counter to achieve a reset condition thereof.  The counter is counted up until occurrence of a rollover signal, which signal is used to prevent passage of any further pulses to the counter and to maintain the counter in an all zero state.  At the input, a hard limited version of the modulated signal is provided to an EXCLUSIVE OR gate together with the reconstructed carrier in order to provide decoding intervals for counting of clock pulses by the counter during the preset integration intervals.

Abstract: ABSTRACT OF THE DISCLOSURE          A device for the wet treating of seed material includes a rotation-symmetrical treating chamber assembled of a conically shaped, downwardly sloping upper wall and of a frustoconical downwardly sloping bottom wall defining a central discharge opening.  A circumferential annular gap connects the upper surface of the upper wall with the inner surface of the lower wall.  A spraying device for a treating liquid is arranged in the treating chamber.  Seed material is fed from a storage container through a gravity pipe arranged concentrically above the upper wall of the treating chamber.  A dosing pipe surrounding a lower part of the gravity pipe is provided near its lower end with an internal expan-sion having an annular bottom surface and a discharge opening, the diameter of which at most slightly exceeds the inner diameter of the gravity pipe.  The dosing pipe is guided for limited coaxial displacement relative to the gravity pipe.  A deflecting surface is disposed concentrically below the discharge opening of the dosing pipe, which is supported via resilient energy storing means perman-ently urging said dosing pipe into a rest position, in which the annular clearance between the deflecting surface and the lower end of the dosing pipe has a predetermined breadth.  The energy storing means and the dimensions of the expansion are mutually adjusted such that during operation the weight of the seed material collected on the annular bottom surface of the expansion automatically regulates the breadth of the annular clearance to provide a uniform flow rate of the seed material.

Abstract: ABSTRACT OF THE DISCLOSURE       A carrier, such as, for example, a printed circuit board, a multi-layer lamination, a metal plate or a carrier layer with metal layers coated on both sides, is heated in a horizontal position on both sides over its entire surface in a heating station and is guided up to a photo-resist film which is fixed vertically on suction plates of vacuum tables and which also spans a laminating station located between the vacuum tables.  The photo-resist film is drawn off from a single supply roll by means of a gripper bar and is guided over the vacuum tables and the laminating station.        A cutting device cuts through the photo-resist film transversely to its longitudinal direction.  The carrier touches the photo-resist film at the height of the laminating station, so that the carrier transported further is pushed into the nip between the rotating laminating rollers of the laminating apparatus, grasped by these and transported through the laminating station, together with the photo-resist film which is laid on to the top side and underside of the carrier.

Abstract: ARTICLE OR SEED COUNTER                   Abstract of the Disclosure A sensor for counting articles, such as seeds, moving through a conduit includes an array of infrared LEDs generating a uniform diffuse beam of radiation which entirely illuminates a cross sectional volume of the conduit.  The beam is detected by a planar photo diode which extends across the opposite side of the conduit.  A pair of mirrors extend along opposite sides of the conduit between the array and the photo diodes.  Slits narrow the beam and limit the amount of radiation which can impinge upon the photo diode.  The signal from the photo diode is integrated by a signal processing unit so that the sensor can count a plurality of seeds in a group of seeds which simultaneously pass through the beam.  The signal processing unit automatically compensates for changes in the steady state photo-diode output and for changes in seed size.

Abstract: Title of the Invention An Ultrasonic Washing Machine Abstract of the Disclosure This invention relates to an ultrasonic washing machine composed essentially of an air bubble supplying device and an ultrasonic generator.   The ultrasonic generator is caused to work with textile products such as fabrics, yarns, ropes, etc. put in a tub filled with water.   Air bubbles produced by the cavitation effect of the ultrasound cling to the sur-face of the textile products and help remove stains, alien matters, etc. adhering to them.   Part of the air, fed from outside by the air bubble supplying device, constantly dis-solves in water, whereby the air consumed by the cavitation is supplemented; the rest of the air, having not dissolved in water, gives the ultrasound more chance to cause diffused reflection on it when ascending in water as bubbles, which serves to improve washing effect very much.

Abstract: Abstract of the Disclosure In a method for heating metal elements which are to be joined, for example by forge welding, a high frequency resistance heating is used.  The elements are provided with surfaces to be welded and are positioned so that said surfaces constitute a narrow gap. The current is conducted from a high frequency current source through a contact into one of the elements, wherefrom the current follows the material close to the gap sur-face and to the opposite side of the element, where the current flows via further contacts and a conductor to the other element.  From here the current follows the other gap surface to another contact and the current source.  The current will follow a path close to the gap surfaces since these surfaces will give the path of smallest total impedance, the current thereby establish-ing a narrow and efficient heating zone in the vicinity of said gap surfaces.
