Abstract: Agricultural distributor, especially a seed drill and fertiliser distributor having a storage bin from which the seed or fertiliser to be delivered is delivered in adjustable amounts via metering members that can be controlled by control members, there being assigned to at least one metering member a sensor which senses the delivered number of the grains of seed or fertiliser, or the amount of the delivered seed or fertiliser, and transmits the corresponding signals to an evaluation computer from which the adjustment of the metering members is determined via the control members. In order also actually to achieve at once the desired sudden change in amount delivered in the case of a desired sudden change in desired value using an agricultural distributor according to the preamble, it is provided that given a sudden change in the prescribed desired value of the amount/number of corns to be delivered the setting of the metering members via the control members is first adjusted by the computer in accordance with the percentage change in desired value, that the values determined by the evaluation computer are likewise simultaneously varied in percentage terms in accordance with the change in desired value, and that these percentage-altered values are then used as the basis for further control. <IMAGE>

Abstract: The density of a foam is controlled by measuring the electrical conductivity of the foam and adjusting its density in response to the measured electrical conductivity. Apparatus for carrying out this method comprises means (10) for generating a foam connected by an enclosed pathway (13) to an application outlet (14). Located within the pathway (13) is an electrical conductivity sensor (15) which is electronically connected (16) to a translation means (17). The translation means (17) is connected (18) to a gas glow controlling means (19) whereby, in response to the signal received from the conductivity sensor (15), the translation means (17) provides a signal to the gas glow control means (19) to vary gas supply to the means (10) for generating the foam. The invention provides an accurate method of controlling the density of the foam within a narrow range, thus enabling the application of the minimum amount of foam necessary to achieve the desired physical properties.

Abstract: The microfilter foil is made of an inorganic substance such as metal with opened pores. Each pore is formed with a channel which increases in cross-section from the crest so as to obviate clogging. The foil is produced by exposure of a photosensitive layer of paint or lacquer with the use of an interference pattern produced by monochromatic and coherent light. A skin of inorganic material is produced on the photosensitive layer and portions of the skin are thereafter removed from the coated teeth in order to produce the pores in the subsequently formed foil.

Abstract: Apparatus and accompanying methods for use therein for measuring and controlling weld indentation during resistance welding operations are disclosed. During a welding operation, the apparatus measures changes in a distance separating a reference point located on an electrode assembly and a region situated on the surface of the workpiece being welded wherein the region is not substantially indented by the electrode. Specifically, a distance measuring system first establishes the location of the surface relative to the electrode before any welding current is passed through the weld area. The indentation is repeatedly measured by detection of ultrasonic echoes from the surface of the material being welded. Such measurements are taken at frequent intervals during the current flow period during which the weld is being formed in order to determine on a continuous basis the indentation of the electrode into the surface. The welding power may be terminated when the measured indentation reaches the desired value. In order to obtain more precise control of the indentation, the rate at which indentation occurs can be measured and the welding power can be changed on a half cycle by half cycle basis to increase or decrease the indentation rate according to a desired indentation program.

Abstract: A self-cleaning canister type filter (1) comprises a cylindrical canister enclosure (3) which has, at one end, end plate (2) with fluid inlets (4) and outlet (6) therein. A spring-loaded hollow annular piston (30) is slideably mounted on the exterior of a central tubular cylinder (10) and within an upper cylinder (28) for a downward movement against a compression spring (32) to initially force a back-flow of filtered fluid through a filter element (14), lifting contaminant particulate solids from its filtering surface (15). An inlet valve opening (64) is opened to fluid flow when piston (30) attains a compressed position. Filter element (14) is closely spaced to the canister enclosure inner wall surface (9) for rapid flow of fluid over the inlet surface (15) of the filter element (14) to scour solids to a sump (5) in the lower portion of the canister enclosure (3). A lower spring-loaded piston (18) communicates with sump (5) and is forced upward by entering contaminated fluid until an attached sleeve valve piston (23) slideably mounted in tubular cylinder (10) opens to permit filtered fluid to exit the filter (1), resulting in normal filtration flow of fluid through filter element (14).

Abstract: In an ignition circuit for a high-pressure metal vapour discharge lamp (205) with a superimposed-pulse igniter (4), it is intended that the ballast inductance (203) should limit the current of a discharge lamp (205) of reduced power to a correspondingly lower value. However, the measure required for this purpose is intended to leave largely unaffected the time interval of the ignition pulses and the frequency of the damped oscillation occurring when the switch element (9) is switched through. This is achieved by now providing a further choke winding (208) as well as the single choke winding (204) used until now to form the ballast inductance (203), which further choke winding (208) preferably has a common choke core with the first-mentioned choke winding (204). The further choke winding (208) is connected only in the lamp circuit (204, 208, 12, 205), but not in the series circuit formed by the first choke winding (204), the impulse capacitor (6) and the auxiliary ignition capacitor (7). <IMAGE>

Abstract: The invention relates to a sheet-metal shearing machine (10) for great lengths of cut with a stationary lower blade (14) and a vertically reciprocal upper blade (17) that can be actuated in a controlled manner. The inventive shearing machine is provided with hydrocylinders (27, 28) for actuating the cutting and withdrawal movement of said upper blade. Said hydrocylinders are coordinated in such a manner that the forces of feed produced by the two hydrocylinders have equal amounts and that the share of load is evenly distributed onto the two hydrocylinders. A main control valve (73) that is pressure-controlled by an electrically controlled pilot valve (83) is provided to control the drive of the hydrocylinders. The shearing machine is also provided with a hydraulic hold-down device (29) with which the metal sheet (11) is clamped down to the base of the shearing machine. A hydraulic accumulator (88) is provided as a source of pressure for the hold-down device (29). Said hydraulic accumulator can be charged by way of a fixed displacement pump (63) in at least one stationary phase of the upper blade (17). The main control valve (73) is configured as a slide valve whose piston (76) has two ranges of stroke  DELTA h1 and  DELTA h2 that directly neighbor each other via an intermediate position (0) and that correspond to alternative operational positions (II and I) of the main control valve (73). A copy stop (128) concurrently performs the feed and withdrawal movement of the upper blade (17) and copies the end position of the upper blade that is facing away from the metal sheet onto the central intermediate position of the main control valve (73). A valve chamber (106) into which the initial pressure of the fixed displacement pump (63) is fed and the hydraulic accumulator (88) are linked with each other so as to communicate in the copying position of the piston (76) and within a stroke range that extends on both sides of the intermediate position (0) that is smaller than the overall stroke ( DELTA h1 +  DELTA h2) of the piston (76). The shearing machine is also provided with a pressure-controlled accumulator-charge valve arrangement (131) that switches the fixed displacement pump (63) to the circulation mode after a charge cycle of the hydraulic accumulator (88). An electrohydraulic control unit (72) activates first the hold-down device (29) before the main control valve (73) reaches the operational position (II) that corresponds to the cutting mode.
