Patent DE-4003418-A1 (DE)
Inventor: RIEGER MARTIN DR
IPC: H03D3/06
Filed: 1990-02-05
Abstract: FM detectors integrated in chips must have external components like ceramic filters or LC circuits in order to attain a good signal-to-noise ratio or prevent thermal drift in the charge carriers. The aim of the invention is to reduce the quantity of external components for setting the internal operating conditions of the FM detector. No external components are used at all; instead, a regulating or control circuit is made with the FM detector on the chip. The regulating circuit essentially consists of a current-controlled oscillator. FM detection in general, but especially for colour television and radio receivers.

Title: Yarn or roving testing - dries the material before testing for more rapid and consistent testing action
Inventor: KUETTEL THOMAS
IPC: G01N33/36
Filed: 1990-08-16
Abstract: To ensure the consistency of yarn or sliver material etc., to be tested such as capacitatively to convert mass swings into signal shifts, the material to be tested is dried first. The material is pref. dried by circulating air in a drying station, with the air fed in and extracted so that the moisture content in the air can be compared and the difference shows the drying measure. During drying, the material is weighed at time intervals, and the weight difference is taken as the measure for the drying action. The material drying is in a kiln or other hot chamber, at about 105 deg C., for 2-4 hrs., or by microwave, or by passing through a heated drying stretch. The material to be tested can be cops, yarn or roving bobbins, or sliver material taken from a can. A drying station (1) for the material is in front of the test station (2), in the direction of material (5) travel, within and through the drying station (1), or the material can be outside the drying station (1) to pass through it before entering the testing stage (2). The drying station (1) has an air inlet and outlet (17) with, at the air entry, a feed shaft (13) with a fan (14) and heater (16). Sensors are close to the air entry and outlet (17) openings to register the air moisture and/or temp., connected to a control unit (20). Weighing scales can be fitted for the material (5) to be tested. The drying station (1) can be a microwave oven. ADVANTAGE - The material can be passed through the testing piont at a faster rate, and the test results give more positive stopping point for actual faults in the material.

Patent DE-4115984-A1 (DE)
Inventor: BERGMEISTER JUN JOSEF
IPC: B60P1/64
Filed: 1991-05-16
Abstract: The semitrailer (1) has two rear stands (15) of constant length and two front stands (17) whose length is automatically adjusted when the semitrailer (1) is parked in such a way that the semitrailer (1) is not subject to torsion stresses during this process. For this purpose, the front stands (17) are constructed as telescopic stands and provided in each case with a hydraulic piston/cylinder unit (24, 25) which are connected to one another via a hydraulic line (28). During the parking process, the hydraulic line (28) opens so that the stand (17) which is first to strike the ground is retracted, the hydraulic fluid which is expelled as a result of this correspondingly extending the piston (25) of the other stand (17) until this stand (17) also comes to rest on the ground. Subsequently, a shut-off valve (29) of the hydraulic line (28) is closed, as a result of which the automatically set length of the two telescopic stands is locked. The semitrailer (1) is suitable in particular for receiving a drum mixer body and can be set down at the building site during a concreting process without there being the risk of the rotary bearing (8) of the mixer drum (7) being damaged as a result of torsion stresses on the semitrailer. <IMAGE>
