Patent DE-3800327-A1 (DE)
Inventor: WINNER HERMANN DR RER NAT
IPC: B60S1/08
Filed: 1988-01-08
Abstract: In a process for operating a windscreen wiper, a beam of radiation (11) emitted by a radiation source (10) is input at a definite angle (16) into a windscreen (13) the outer surface (14) of which is to be cleaned by a windscreen wiper. The angle (16) is closen so that the beam (11) is totally reflected at the outer (14) and inner (19) surfaces of the windscreen, from which it emerges at a particular position and is directed to a radiation receiver (21). When the outer surface (14) of the windscreen is wetted with drops of water (22-25), a loss radiation (28, 29) is output. This results in a reduction of the signal (43) emitted by the radiation receiver (21). If the signal (43) falls below a threshold by a predetermined amount, a cleaning process of the windscreen wiper is initiated. The threshold is established in function of the peak value of the signal (43). The measured peak value is stored, the input time being appreciably shorter than the duration of storage.

Title: Cue with a rubber floor support
IPC: A63D15/12
Filed: 1988-08-23
Abstract: A cue with a rubber floor support (16) at the butt end (1) is so designed, according to the invention, that impact forces from setting down are transmitted from the cue to the rubber floor support (16) by a compression spring (3) supported at the butt end (1). It has become habitual for billiard players occasionally to rap the butt on the floor with the cue positioned vertically. When this is done, the impact noise from the known rubber floor supports is transmitted to the room situated under the billiard room which is also sometimes used residentially. By contrast, the cue according to the invention avoids propagation of sound in the event of an impact on the floor. <IMAGE>

IPC: F22G5/12
Filed: 1988-12-10
Abstract: A steam conversion process, in which live steam of a thermodynamic state 1, governed by temperature TFD and pressure pFD, is converted into exhaust steam of a thermodynamic state 2, governed by temperature TAD and pressure pAD, by means of a steam conversion valve with cooling water injection, the live steam passage (flow rate mFD) and cooling water throughput (mass flow mKW) of which can be varied by the adjustable stroke of a valve body in the steam conversion valve and in the cooling water valve, respectively, the steam conversion valve interacting with at least one controller which produces at least one controlled variable as a function of temperature and/or pressure of the exhaust steam (TAD; pAD) and influences the cooling water throughput by means of the manipulated variable transmitted by the controller to the auxiliary drive, is to be further developed such that a reliable operation of such valves is achieved, the intention being in particular for it to be possible to adapt the behaviour of the controller to deviations of the valve from its ideal characteristic, caused during production or by wear. For this purpose, the stroke of the valve body of the steam conversion valve is picked up, its value is fed to the computer, which calculates from it the live steam mass flow mFD passing through the steam conversion valve, and the associated heat flow, and so too is the stroke of the valve body of the cooling water valve, from which the computer calculates the cooling water mass flow mKW passing through the cooling water valve and also calculates from the mass flows of live steam and cooling water, taking heat balance into consideration, the values to be expected for temperature T'AD and pressure p'AD, which the said computer then compares with the measured values TAD and pAD and derives from them in a way known per se the manipulated variables for controlling the cooling water injection. <IMAGE>

Patent DE-3909039-A1 (DE)
Title: Pressure regulator
Inventor: LINZ DIETER
IPC: G05D16/06
Filed: 1989-03-18
Abstract: In order to reduce a gas from a high to a lower pressure level, to hold the operating pressure constant and to seal off the connection between high and low pressure space, pressure regulators (19) require a desired value transmitter (setting spring or control pressure) and a closing spring. Desired value transmitters in known pressure regulators are adjustable from outside the pressure regulator housing, while the closing spring force can be adjusted only inside the pressure regulator housing. Adjusting the closing spring force is possible in this case only in the disassembled state of the pressure regulator. Pressure regulators which are used in the low pressure range need, apart from a setting spring and a closing spring, a bias spring by means of which the low pressure diaphragm can be biased against the operating pressure. According to the invention, therefore, a pressure regulator for gases of high purity is proposed in which a closing or bias spring (6) can be adjusted from outside the pressure regulator housing (13) (Fig. 1). <IMAGE>
