Title: Checking of heat exchanger efficiency - by shutting off flow through heat exchanger tubes and measuring temp. rise
Inventor: BODMER MAURICE DR
IPC: F27D21/00
Filed: 1991-06-15
Abstract: In order to check the efficiency of heat transfer in a heat exchanger or cooler, the tubes of the heat exchanger or cooler are sealed for a period of between 0.5 and 3 minutes and the temp. rise of the water retained in the tube is then measured. The tubes (10) are sealed at one end by plugs (13) which have hemispherical heads (6) and conical bodies (15).

Patent DE-4135681-A1 (DE)
IPC: B23D37/00
Filed: 1991-10-30
Abstract: The rotationally symmetric workpiece surface (9) rotates during the machining and is first of all rough-machined and then finish-machined by means of a cutting tip (8). During this finish machining, the workpiece surface (9) is machined by a divided cutting-edge arrangement (22 to 28) of the cutting tip (8) by the longitudinal turning process. The tool (1) is fed in radially to the workpiece surface (9) during the finish machining and is moved in the axial direction of the workpiece surface (9) for the longitudinal turning by means of the cutting tip (8). The cutting tip (8) has at least two cutting edges (22 to 28) which lie axially next to one another at a distance apart and with which the finish machining is effected. The finish machining by longitudinal turning has the advantage that the cutting edges (22 to 28) do not change their position relative to the workpiece surface (9) during the finish machining and can be arranged in such a way that only slight forces result. The cutting edges are subjected to only slight wear, and the corresponding workpiece is only slightly deflected. A tendency to chatter during the finish machining is thereby avoided and a high machining accuracy is achieved. <IMAGE>

Title: Reusable fluid and food container - has tubes tightly fitted in sealing closure and having airbags and pumps to exclude contact between air and contents to avoid contamination
Inventor: HAG RENE
IPC: B65D81/24
Filed: 1992-05-16
Abstract: A tube (R-1) fitted tight in the bottle closure (V-S) has an air pump (L-VAk-1) and an inflatable hygienic valve (V-1) at the end outside the bottle so that a measurable amount of fluid or other substance can only be let out by letting air into an inside air-breaker balloon (LuB-1) which, when inflated, can fill up the entire bottle.

Title: Removing organic contaminants from soil - by using super-heated steam at 220 deg.C to reduce energy used, and cost
Inventor: RIED MANFRED DR
IPC: B09C1/02
Filed: 1992-08-11
Abstract: In a process to remove organic contaminants from contaminated soil the novelty is the contaminants are driven out by super-heated steam at 220 deg.C. Steam is generated (1) in a boiler and fed to the charge (2) from which it emerges to a condenser (5). Vaporised contaminants and the steam are subsequently condensed and separated. The condensed steam is reheated and returned as steam for reuse. In the presence of sulphurous compounds an additional installation (4,9) is located upstream of the condenser. USE/ADVANTAGE - The process removes organic impurities from soil. The process requires only a limited amount of energy and thus operates at low cost.

Title: Operating procedure for switched voltage regulator - controlling duration of setting element switching-in pulses in dependence on switched regulator input voltage amplitude
Inventor: GRUENSCH ECKHARDT
IPC: H02M3/335
Filed: 1992-10-20
Abstract: A current control is used in which the current (I) in the energy utilisation phase is controlled in dependence on the amplitude of the switched regulator output voltage (UA). When the switched regulator input voltage (UE) is raised, the switching-in pulses for the switched regulator setting element (ST) are shortened, with corresponding lengthening of the pause times between the switching-in pulses. Pref. the setting element switching-in control (ES) uses a comparator (K1) comparing the output voltage and utilisation current with a reference value. The switching-out control (A5) uses the input voltage amplitude for dynamic control of a discharge resistance (Ur2, T1, R3) for a capacitor (C) provided with a charging circuit (Uh, R1, R2, T2) the switching signal for the setting element being supplied in dependence on the capacitor charge. ADVANTAGE - Simplified switched regulator setting element control circuit, allowing maintenance of constant operating frequency.

Patent DE-4311925-A1 (DE)
Inventor: MAST MARTIN DIPL ING
IPC: G01F23/14
Filed: 1993-04-14
Abstract: Variations in a pressure signal during travel over stretches of poor road surface are used to detect such stretches of poor road surface. The arrangement shown has a differential pressure sensor 12 at the bottom of vehicle fuel tank 10. The sensor receives atmospheric pressure P1, tank bottom pressure p2, and tank gas space pressure p3. Besides determining the filling level and the gas pressure (tank venting diagnosis), a differential pressure sensor is therefore simultaneously capable of providing detection of poor road surfaces e.g. for use in determining combustion misfires of the i.c. engine. The detection circuitry described passes the fuel level signal (p2 - p3) through a high-pass filter (Fig. 2 not shown). <IMAGE>

Title: Bearing for wheel-guiding links for setting the camber and castor of vehicle wheels
Inventor: ZIVKOVIC MILORAD DIPL ING
IPC: F16F1/38
Filed: 1993-07-15
Abstract: The invention relates to a bearing for wheel-guiding links which are articulated in mounts in the top section of vehicles and are intended for setting the camber and castor of vehicle wheels suspended via the guiding links. In the case of said bearing, a bearing bushing connected elastically to the guiding link can be firmly clamped in the mounts in a manner which allows it to be adjusted parallel to the axis. The intention is to simplify the construction of said bearing and the manipulation of its adjusting device. The intention in particular is to make automatic initial assembly possible. For this purpose, the bearing bushing is clamped in the mount by a stud which is mounted in the mount in a manner free of axial displacement, whilst the bearing bushing can be displaced axially. In this arrangement, the stud is interlocked with respect to the bearing bushing, in the zenith or nadir thereof, in order, as a result, to be able to bring about axial displacement of the bearing bushing when the stud is rotated.
