Title: Method and device to determine the service time for changing brake fluid
Inventor: KLEIN JOACHIM DR
IPC: B60R16/023
Filed: 1988-06-15
Abstract: Method and device for determining the service time for changing brake fluid. A first and second time element are provided, which are provided for the measurement of the age of the brake pipe or the brake fluid. The output signals of the time elements are processed in a combining circuit with a predetermined algorithm to form a combined signal. The combined signal is compared in a comparator with a reference value, a control signal being given to an indicator device as a function of the comparison carried out in the comparator. A sensor for the determination of the over-temperature of the brake above a preselectable temperature value is provided on the brakes of the motor vehicle. In an evaluation circuit, an output signal is generated which is proportional to the time interval of the existence of an over-temperature of the brake. The combined signal is so modified, that the unusual brake-loading processed in the evaluation circuit is taken into the calculation of the time of the triggering of the control signal.

Title: Distributing device for spreading material
Inventor: STACHNIK WINFRIED ING GRAD
IPC: A01D41/12
Filed: 1988-07-16
Abstract: What is to be proposed is a distributing device (38) for spreading material, especially for chaff and short straw, which is arranged in a discharge region of a conveyor, for example of a screen box of a combine harvester, and which has guide elements (46) for the controlled discharge of the spreading material and a catching element (47) for receiving the spreading material. To avoid high costs, a distributing device (38) unsusceptible to faults is to be provided by means of few parts. There is therefore provided a roller-shaped rotary body (40) which can be driven at high speed about an axis extending transversely relative to the conveying direction of the conveyor and which, by means of throwing elements (42), throws the spreading material to guide elements (46) which direct it on to the ground in a controlled manner. Distributing devices (38) of this type are used especially in combine harvesters for the uniform discharge of chaff on to the ground. <IMAGE>

Title: Laundry mangle
Inventor: BAUMANN ROLAND DIPL ING
IPC: D06F67/00
Filed: 1988-08-04
Abstract: In a laundry mangle, the quantity of waste air used for discharging the liquid expelled from the mangling material is regulated in dependence on the actual value of the temperature and on the relative humidity of the waste air. Regulation takes place by approaching a desired value for the relative humidity which is defined by a regulating curve filed in a memory. This regulating curve has two branches; below 100@C, it corresponds to the constant value 100%. Above 100@C, the regulating curve has a descending branch which corresponds to the quotient of the atmospheric pressure and the vapour pressure of water at the corresponding temperature, multiplied by 100. In this way, the quantity of air which has to be sucked in by the blower in order to discharge the moisture which occurs can be kept at the lowest possible value (Figure 3). <IMAGE>
Patent DE-3826592-A1 (DE)
Inventor: KINDERMANN WOLFGANG
IPC: F01D17/26
Filed: 1988-08-04
Abstract: The present invention relates to an actuator for a quick stop valve (1) in a steam line (3a, 3b, 3c), preferably in a steam turbine. Arranged on the torque shaft (11) of the quick stop valve (1) is a pinion (12) with which two pairs of racks (13, 14) engage. One pair of racks (13) serves in conjunction with hydraulic means (6, 8) to open the quick stop valve (1), the other pair (14) serves in conjunction with closing springs (7) for the purpose of rapid closure. By virtue of complete freedom from play, the two independent systems for opening or closing reduce the wear of the mechanism, and via an appropriate hydraulic connection enable damping of the valve disc of the quick stop valve (1) upon entry into the final closing position. In order to keep this damping independent of different operating states, use is made of manometric balances (26a, 26b) in conjunction with an interceptor throttle (27), which can also be adjustable depending on the angle of rotation. A bypass line (4) which for its part can be blocked by a quick stop shut-off valve (5a, 5b), serves the purpose of relieving the pressure of the quick stop valve (1) during opening. <IMAGE>

Title: Arrangement for processing timing commands
Inventor: BIER GERHARD DIPL ING
IPC: G04G15/00
Filed: 1988-12-05
Abstract: The invention relates to an arrangement for processing timing commands. For many applications in data processing, e.g. in programmable controllers, there is a need for programmable times for the time-dependent control of cycles. A simplification of the timing control is achieved by the arrangement according to the invention by providing that a timing control unit (ZST) which contains a reference clock, which supplies reference times, and an evaluation unit (AE), determines the maximum operating (back-up) times (R) by adding the response (lag) times (T) to the respective reference time and stores them in a time register (ZS) and when the response time (T) is interrogated reads out the stored maximum operating times (R) from the time register (ZS) and compares them with the current time value (AZ) of the reference clock. If the current time value (AZ) is greater than or equal to the maximum operating time (R), this indicates the response time (T) has expired. The invention is applied in data processing systems (equipment), in particular in programmable control units. <IMAGE>
