Patent DE-4107295-A1 (DE)
Inventor: RITSCHEL MANFRED DR RER NAT
IPC: G01N25/18
Filed: 1991-03-07
Abstract: In a method for determining chemical and/or physical properties of a gaseous atmosphere, the gaseous atmosphere of interest is brought into contact with a heatable surface and the resultant changes in temperature are converted to an electric signal. The invention proposes that the heatable surface be heated by supplying energy at regular intervals throughout a predetermined period (heating cycle) and that the heat emission from the surface, which depends on the gas atmosphere of interest, be measured and the variation of temperature with time be evaluated in order to produce a measurement signal. The essence of the method is therefore the determination of the variation of temperature with time. Consequently, only specific limit values are to be given, and only the time which elapses until this value is reached is measured and compared with calibration values. In addition, the resultant reduction in current consumption prolongs the autonomy of portable appliances.

IPC: G01R31/04
Filed: 1992-02-13
Abstract: 2.1 In known test devices which have a receiving part and an interlocking device, both components are permanently connected to one another. In practice, only some of a large number of test devices are in each case used at the same time so that the remaining interlocking devices, which are relatively expensive to produce, remain unused. It is the object of the invention to provide for better utilisation of the test devices, particularly the interlocking units in order to lower the costs. 2.2 For this purpose, it is provided that the interlocking device (3) is detachably connected to the receiving part (1), both the interlocking device (3) and the receiving part (1) exhibiting mutually corresponding holding means by means of which the interlocking device (3) can be fixed at the receiving part (1). 2.3 It is now possible to detach the interlocking devices from the receiving parts which are currently not being used, the interlocking devices then being connected to the receiving parts for which a use is planned. It is now no longer necessary to provide each test device with interlocking devices, which results in considerable cost savings. <IMAGE>

Patent DE-4214991-A1 (DE)
Inventor: BOUIS XAVIER
IPC: G01M9/04
Filed: 1992-05-06
Abstract: The walls (11, 12, 13, 14) of a wind tunnel (10) contain slots which extend longitudinally in the test region (18) and behind which grooves (19) are formed. Each of the grooves (19) contains a flexible base (22) which can be brought into a desired form with the aid of adjusting means. As a result, the influences of the wall on the air flow are reduced and rendered more amenable to calculation. This concept reduces the influences of the wall on the model investigations (improvement of the wind tunnel simulation) and permits a more accurate and reliable calculation of the remaining residual influences. <IMAGE>
Patent DE-4219005-A1 (DE)
Inventor: REINMUTH ARMIN DIPL ING
IPC: G06F11/18
Filed: 1992-06-10
Abstract: A computer system has several interconnected processors (P1, P2, P3) each associated with a memory (S1, S2, S3). The memories (S1, S2, S3) all have a common storage area (SB) to which the processors (P1, P2, P3) have access. In order to synchronize changes (BZ0, BZ1, BZ2) in the state of operation of the processors (P1, P2, P3) and/or to handle processor jobs in a synchronous manner, the first processor to reach a predetermined synchronization point (MP1, MP2; WP1 ... WP3) writes a data set in the common storage area, causing interrupt controllers (IC1, IC2, IC3) associated with the processors (P1, P2, P3) to generate interrupt signals and to initiate changes in the state of operation or synchronous job processing. The invention has applications in multiple processor systems, redundant computer systems and stored program control systems.

Inventor: LOEHNERT KATHARINA
IPC: C09K3/00
Filed: 1992-06-12
Abstract: Water bed mattress filling consists of a slurry of 1-7% synthetic pyrogenic amorphous silic acid in water, thickened by the addn. of 0.003-1.5 wt.%, esp. 0.1 wt.% of polyethylene glycols with a mol.wt. of greater than 600 to less than 600,000 or derivs. of polyethylene glycols such as their ethers with alcohols or amines or their esters with carboxylic acids having a mol.wt. of greater than 600 to less than 600,000, or of polyethyleneimine.
