Title: Hydraulically-controlled hydraulic system resistance - has valve spring chamber connected to inlet and to pilot valve chamber
Inventor: KURZ MANFRED DIPL PHYS
IPC: F15B13/02
Filed: 1980-12-15
Abstract: The hydraulically-controlled individual resistance is for use in a hydraulic system containing a pilot-controlled 2-way valve with slide. The slide incorporates throttling slots and is subjected to the action of a return spring in a spring chamber. The spring chamber is connected by a passage into which the pilot current discharges via a nozzle, to the inlet, and also to the spring chamber of a pilot pressure difference valve. The pressure chamber opposite the latter spring chamber is connected to the supply passage. A portion of the pilot valve slide has a flange of larger dia. than the two slide end faces, which are pref. the same dia. One of the annular faces so formed is subjected to the supply pressure and the other to the discharge pressure so that the stroke of the two-way valve slide, which is proportional to the difference between the supply pressure and the control pressure in the spring chamber of this valve, is also proportional to the difference between supply and discharge pressures.

Abstract: A joint pin seal for a caterpillar track. The join pin seal comprises a support ring of hard elastomer material having a cylindrical inner wall. The support ring is firmly pressed in a housing bore which is adjacent a relatively movable machine part to be sealed. The support ring comprises a stiffening ring contacting the rear wall of the housing bore and a lip ring adjacent the machine part to be sealed. The lip ring has a sealing lip which presses against the surface of the machine part to be sealed. The stiffening ring is tapered in notch-like fashion into said lip ring forming a membrane at the transition into the lip ring and provides the support ring with a notch between the lip ring and the stiffening ring. A pressure ring, formed from a softer elastomer material, is disposed within the notch and contacts the housing bore wall. The pressure ring presses the sealing lip into the relatively movable machine part to be sealed. The ratio of the average radial distance from the membrane to the sealing lip to the average radial distance from the center line of the pressure ring area contacting the lip ring to the sealing lip is about 0.7 to 1.4.

Title: Method and device for the automated adjustment (calibration) of measuring instruments and transducers of physical input variables
Inventor: PICHL ORTWIN DIPL ING
IPC: G01D18/00
Filed: 1981-12-17
Abstract: A method and device for the automated adjustment (calibration) of measuring instruments or transducers of physical input variables into electrical, preferably digitally displayable output variables and possibly for the repeated automatic readjustment, the measured system being supplied with correcting variables, obtained by comparison of stored setpoints with numerical values resulting at the output of the measured system, at least for zero point and range in digital form during the adjustment. At the input of the measured system, a switch-over device is provided which, after completed calibration with external calibration standards, switches the measured-system input into a digital/analog converter which produces the output signal of the measurement pick-up, which is determining for the respective calibration process, until the numerical values at the output of the measured system are identical. The digital input variable for the digital/analog converter then corresponds to the measurement standard and is stored as quasi measurement standard, which can be called up at any time for repeated recalibrations, in a measurement-value store. Furthermore, possibilities are provided for mathematical linearising non-linear characteristics of the measurement pick-up and for mathematically taking into consideration other environmental influences (temperature) on the measurement pick-up.

Title: Loosening device for bulk products as a discharge aid for containers
Inventor: HARMS SIGURD
IPC: B65D88/62
Filed: 1982-05-27
Abstract: The invention relates to a loosening device for bulk products, in particular for non-free-flowing or cohesive bulk products, as a discharge aid for containers, in particular silos and hoppers. According to the invention, the loosening device consists of a dual-walled, flexible, conical or cylindrical hollow body which is embedded in a bearing construction and surrounds the column of bulk products situated in a container. According to the invention, the flexible hollow body is provided with two or more feed connections for a pressure medium, which serve for applying superpressure, atmospheric pressure and negative pressure alternately to the hollow body. According to the invention, this results in the flexible hollow body having three different basic shapes depending on the type of pressure selected, specifically an inflated shape when superpressure is applied, the relaxed basic shape when atmospheric pressure is applied and a shrunken shape when negative pressure is applied. A control device, covered by Patent Application No. P 3231759.5, allows negative pressure, atmospheric pressure and superpressure to be applied alternately to the flexible hollow body, which results, due to the alternate inflating and shrinking of the flexible hollow body, in a pulsating, sinusoidally moving function sequence which can be equated to a breathing effect. By means of this pulsating breathing effect of the flexible hollow body surrounding the column of bulk products, negative types of flow characteristics of bulk products, in particular the formation of bridges of bulk products, dead zones and caking on container walls are avoided.

Title: Method and device for the open-loop or closed-loop control of the roll gap setting in rolling mills for flat strips or sheets
Inventor: IHLEFELDT JUERGEN DIPL PHYS
IPC: B21B38/02
Filed: 1982-09-20
Abstract: The invention relates to an improved method for the determination of actuating or control variables for roll gap setting in rolling mills for flat strips or sheets. These actuating or control variables are, as is known, determined from the tensile stresses in the rolling stock, the said stresses being measured with the aid of measuring rollers distributed across the rolling stock. According to the invention, in contrast to known methods, the measured values of the measuring rollers running at the edges of the rolling stock are also evaluated. For this purpose, the overlap of the rolling stock at the measuring roller running at the edge is determined by measuring the exact position of the edge. The exact position of the edge is determined by irradiating the edge region, this radiation being screened off or reflected to a greater or lesser extent depending on the position of the edge and measured in a radiation receiver. Suitable forms of radiation are ultrasound, thermal, luminous or electromagnetic radiation with a wavelength of 2 to 30 mm. <IMAGE>

Title: Additional cooling for air-cooled motor vehicle engines
Inventor: WILKE HARALD DIPL ING
IPC: F01P9/04
Filed: 1982-11-27
Abstract: The subject-matter of the invention is additional cooling for air-cooled internal-combustion engines for motor vehicles, especially cars and small buses. In air-cooled engines, there are certain difficulties with respect to the construction of the cooling ribs relating to the ratio, which is essential to the cooling effect, of the wall surface to the volume enclosed by the walls. The object of the invention is, by improving the cooling, to achieve a reduced stress, especially of the thermally highly-loaded engine parts, or to maintain the same stress at higher power. According to the proposal of the invention, this is achieved by the region surrounding the combustion chamber of the cylinder or cylinders being additionally cooled by means of engine lubricating oil.
