Process and apparatus for controlling a controllable magnitude and use

A process and apparatus are disclosed for continuously determining the moisture content of a spoilable foodstuff, in particular, of grain and processed products of the latter, which is moved along a production line as a product stream and passed, at least in part, through a measuring section of a housing in accordance with the process, a pourable average of the product stream is created continuously within the measuring section, and the product moisture content of this product average is measured electrically on a continuous basis. In accordance with the device, the measuring housing has a capacitor as a continuous-flow measuring section and a device for continuously controlling the creation of a pourable product average. One of the central concepts of the invention is found in the interaction of the following factors: --continuous creation of a product average, continuous trickling-type flow of the product, with simultaneous electrical measurement on a continuous basis.

Method and apparatus for the continuous determination of moisture

A process and apparatus are disclosed for continuously determining the moisture content of a spoilable grain product which is moved along a processing line as a product stream and passed, at least in part, downwardly through a measuring section of a housing in accordance with the process, a pourable average of the product stream is created continuously within the measuring section, and the product moisture content of this product average is measured electrically on a continuous basis. In accordance with the device, the measuring housing has a capacitor as a continuous-flow measuring section and a device for continuously controlling the creation of a pourable product average.

A separating contrivance for separating cereals and similar grain product into at least three grain fractions and heavier impurities comprises two air-penetrable fluidized bed tables (2, 3) arranged one over the other and supported in fashion capable of being oscillated in relation to a frame, with a product inlet (9) leading to the upper fluidized bed table. At one end of the contrivance, and spaced away from the inlet (9), the upper fluidized bed table (2) is provided with outlets (10, 18) for the light and medium heavy grain fractions, while the lower fluidized bed table (3) includes outlet (27) for the heavy grain fraction. Adjoining the other end of the lower fluidized bed table (3) is an outlet (16) for the heavy impurities such as stones and the like. In order to achieve a practically complete sorting of the heavy impurities, provision is made so that the two fluidized bed tables (2, 3) are supported independently of one another and are driven by separate oscillating drives (7, 25).

Procedure and mechanism for the automatic control of a grinding mill

A method and apparatus for the cyclical counter-scavenging of filter hoses, particularly the control thereof, is disclosed. According to the present invention, the counter-scavenging of filter hoses is accomplished by gas blasts whose timing and duration are controlled by a fluid control apparatus. The fluid control apparatus consists of a drum distributor having an arm whose position controls the timing of the counter-scavenging blasts, and a valve whose activation controls the duration of the counter-scavenging blasts. The drum distributor and the valve are independently controllable by an electronic circuit including timing signals and control circuitry receiving the timing signals and converting these signals into activating signals for the drum distributor and the valve.

The device is of the type including a balance beam pivotally connected to a housing, an inclined measuring plate, adapted to deflect a product stream supplied in metered quantities and flowing off by gravity, mounted on the balance beam in a position in which its measuring surface extends substantially parallel to the longitudinal axis of the balance beam, and a mechanism in the housing, operatively associated with the lever arm of the balance beam remote from the measuring plate, and operable to act on such lever arm, in opposition to the effect of the deflecting force acting on the measuring plate, to produce a variable proportional to the time rate of the product flow and represented by a preferably pneumatic signal, resulting from oscillation of the balance beam about its position of equilibrium, this signal constituting the basis of either a measurement or a flow control derived from the signal.

Device for measuring the rate of flow of flowable products, particularly

A feeler is moved in a defined space at a predetermined level in alternately opposite directions. If the level of particulate material in the space reaches or exceeds the predetermined level, the movement of the feeler encounters resistance which is sensed, and in dependence of which the level of the particulate material in the space is controlled.
