Title: Tank for treatment of foodstuffs contg. solid and liq. components - esp. red wine mash where tank dimensions provide optimal tank size and agitation effect for least capital cost
Inventor: RIEGER HERBERT
IPC: B01F7/02
Filed: 1990-03-27
Abstract: Tank for treatment of foodstuffs contg. liq. and solid components has a verticial cylindrical section (11) with a roof (12) and a floor (13), and an agitator (40) with a horizontal shaft (41). This agitator (40) traverses an approximately spherical reigon which is essentially impassable to the solid component. Novelty is that the vertical cross-section of the roof (12) should be made up of straight lines, and that the vertical distance (z) from the axis (42) of the agitator shaft (41) to the mid-point (15) of the roof (12) should be determined by the following relationship: z = k1H + k2R where H is the ave. internal height of the tank, R is the radius of the cylindrical tank section (11), k1 is a constant in the range 0.07-0.13 and k2 is a constant in the range 0.6 and 0.9. The distance (z) is also at least as great as the radius (R). The pref. values of the constants are k1 = 0.1 and k2 = 0.7, and the ratio of the height (H) to the dia. (D) of the cylindrical tank section (11) lies between 1.0 and 3.5 and is pref. equal to 1.5. USE/ADVANTAGE - Used in the design of tanks for the treatment of foodstuffs contg. liq. and solid components, and esp. for the treatment of red wine mash in which the mixt. is periodically agitated during fermentation in order to promote the extn. of the red colour from the grapes while avoiding damage to the grape skins, which would release undesirable constituents. The proposed tank occupies little space and provides the optimal tank size and agitation effect at the least possible cost.

Title: Producing control pressure in hydraulic plant -  involves primary control valve to which control pressure conduit is connected
Inventor: BUETTNER PETER
IPC: F15B13/042
Filed: 1990-08-24
Abstract: In the delivery conduit (2, 4) of the hydraulic plant a primary control valve (1) is incorporated, in the regulating position of which the pump delivery flow is divided between the user equipment and a control pressure conduit (3). To produce the control pressure, the chambers on both sides of the primary control valve piston are connected to one another, and the piston is pressed into the regulating position by a spring (12). In this position, the control pressure is determined by a pressure limiting valve (18) connected to the control chamber on the spring side. The connection between the control chambers on both sides of the primary control valve is by means of a valve which is switchable so that the control pressure is effective in both chambers. USE - To produce a control pressure in a hydraulic plant.

Patent DE-4105517-A1 (DE)
Inventor: LEBOWSKY FRITZ
IPC: G06T5/20
Filed: 1991-02-22
Abstract: The method disclosed is intended for filtering signals in which the signal amplitudes can be allocated coordinates in a quantized two-dimensional reference plane. In order to amplify the useful-signal component, constant and high-frequency components are filtered out and the filtered signal added to the unfiltered input signal. The signal is filtered by means of a band-pass filter followed by elimination of signal components having an amplitude below a given threshold value. Isolated signal components within the reference plane are subsequently eliminated, and then the signal reconstructed by interpolation for the coordinates in the reference plane at which the amplitude of the filtered signal component is substantially zero.

Title: Measuring operating and reversal point of limiter - using first phase to determine change regions and second to accurately measure input signal at instant of change
Inventor: LUOTSINEN OSMO
IPC: G01D1/18
Filed: 1992-02-20
Abstract: A method of measuring the operating and reversal points of a limiter involves feeding a variable signal to the limiter and recording the input signal and direction of the change of state at the instant of a change of the limiter's state. The variable input signal is fed in two phases. In the first phase the signal is changed at a rate which does not enable determination of the accurate value of the input signal at the instant of change but enables determination of regions (A,B) in which the change occur. During the second phase the signal is varied within these regions (A,B) at a rate enabling accurate measurement of the input signal at the instant of change. USE/ADVANTAGE - The method of measuring operation and reversal points of limiter enables increased measurement accuracy to be achieved with a reduced measurement time.
