Patent DE-3826945-A1 (DE)
Inventor: GIEBNER ERICH
IPC: F16C25/06
Filed: 1988-08-09
Abstract: The clearance or preloading of a rolling bearing 10, which supports a work spindle, is controlled by using a fluid. The forces acting on the bearing during operation are measured and the force-measuring signals are used to generate control signals for controllable valves 15, 16, 17, by which the flow of fluid fed to the bearing or its structural components 11, 12 is controlled. As shown fluid of different temperatures is supplied to the inner and outer rings 11, 12 of the bearing in dependence of the signal output generated by the force measuring sensors 13 to thereby heat/cool the respective bearing parts to control bearing clearance or preloading. In an alternative embodiment (Fig. 2 not shown) it is the flow rate rather than the temperature of fluid which is controlled to each respective bearing part. <IMAGE>

Title: Boosting compensating pressure between test medium - and reference electrode, by auxiliary hydrostatic difference
Inventor: ELSPER RUEDIGER
IPC: G01N27/28
Filed: 1989-05-29
Abstract: Analytical measurements on liq. travelling in a conduit (e.g.1) are made by an inserted ref. electrode (2) or a corresp. bar element supplied with electrolyte from a supply (5) below a gas cushion (6). Contamination of the sepg. diaphragm by expelled electrolyte is countered by pressure difference applied between test liq. and electrolyte. In addn. to pressure from the test liq. auxiliary pressure is derived hydrostatically from the height difference below the upper boundary between the electrolyte and its gas cushion (6), and the lower boundary (8) between test liq. medium (9) in a side chamber and its gas cushion (10). Enclosed gas is compressed by the test medium, and itself transfers pressure. Alternatively a pre-compressed gas charge is used, or pressure applied by a floating piston subjected to pressure from both involved media. ADVANTAGE - A simpler method than known use of pre-stressed bellows.

Inventor: ADAM GOTTFRIED DIPL ING
IPC: G01N15/08
Filed: 1990-04-11
Abstract: The proposed process makes it possible to determine the diffusion coefficient (D) from the pressures (p1, p2) and temperatures (T1, T2) measured in two chambers (1, 2) mutually separated by an elastic diaphragm by iteratively solving an equation representing the Flick's second law and initially solved with an assumed value for the diffusion coefficient using (D) until the calculated concentration c2 in the second chamber (2) agrees with the value determined from the measured pressures and temperatures. It is also possible to obtain the permeation coefficient (Q) by using the ambient temperature (TO) and pressure (pO). The values found are plotted on a graph which makes it possible to see when the experiment has entered a stationary state and the value then found may be regarded as the final one. The proposed device for implementing the process has a computing device (8) for making the necessary calculations in real time. The device remains closed during the experiment, thus facilitating operations with hazardous gases. There is no need for the difficult measurement of small volume currents. Thus the measuring process of the invention has distinct advantages with respect to measuring time and accuracy.

Filed: 1990-07-26
Abstract: In systems using a pressure medium, in particular hydraulic systems, system-inherent pressure variations occur in the consumer feed flow, i.e. noise which interferes with the use of the system. To damp out such pulsations or noise, the invention calls for a hollow spherical to egg-shaped cavity with a multi-layer sound-absorbing surround, and with staggered input and outlet bores, as a pulsation-absorption chamber. The pulsation-absorption chamber can be used in any application, can be retrofitted if necessary, and ensures efficient, cost-effective noise and pulsation reduction. Other embodiments of the invention concern particular designs of the pulsation-absorption chamber and its surround.
