Patent DE-3716324-A1 (DE)
Title: Mounting system for the warning devices stipulated in paragraph 53b-STVZO (Road Traffic Licensing Regulation) for mounted implements
Inventor: BERTSCHE JOHANNES
IPC: B60Q1/26
Filed: 1987-05-15
Abstract: Problem   - Some of the commercially available warning devices offered for the purpose of distinguishing mounted implements can, depending on the type of mounted implement, only be attached with great difficulty to said implements. Because the attachment is awkward the warning devices are very often not displayed. In practice this leads to avoidable accidents which have nasty consequences. - The location and manner of storage of the warning devices removed whilst work is being carried out with the mounted implements remains up to the user, which very often has the consequence that the warning devices are damaged or rendered unusable because of unsuitable storage. - The warning devices are not immediately available when they are required.   Solution of the problem   - Mounting system which permits the warning devices to be attached and removed simply and without any difficulty and also permits the exchange of mounted implements. - Mounting system which permits the warning devices to be deposited during work at secure and protected positions on the mounted implements. - Mounting system which permits the warning devices to be deposited in a secure and protected manner on that motor vehicle where the mounted implements are used. This measure results in the warning devices being immediately available if required.   Area of use - On all mounted implements which have to be safeguarded in accordance with paragraph 53b-STVZO with warning devices for distinguishing the mounted implements.

Title: Method for reducing the speed of articles transported in a pneumatic transport system and apparatus for carrying out the method
Inventor: TSUBATA YUKIHIRO
IPC: B65G51/02
Filed: 1988-01-15
Abstract: Method for reducing the speed of articles transported in a pneumatic transport system, in which the speed of the articles which are transported by means of an airflow in a transport pipeline is reduced at a point just before the outlet end of the pipeline. The method provides that air passages are formed at points situated shortly before the outlet end of the pipeline in the direction of movement of the articles, and that, at the air passages, air is removed at a suction rate which exceeds the volume of the airflow for the transport of the articles, so that the speed of the articles is reduced by an air counterflow flowing in through the outlet end of the transport pipeline.

Patent DE-3811253-A1 (DE)
Title: Shoe for walking and sliding on snow
Inventor: TOLLKIEN RALF
IPC: A63C5/00
Filed: 1988-04-02
Abstract: The invention provides a means of movement for walking and skiing in snow, and optionally also for emergency use in deep snow, which permits problem-free walking and sliding in all snow conditions, especially in deep snow - even on ascents and descents - and is suitable at the same time for mountain descents and for forward movement on flat terrain (by using runners to generate propulsion). The apparatus, equipped with a large bearing surface, possesses adjustable runners which - in contrast to articulated flaps -engage immediately, utilise a large transverse surface and permit infinitely variable adjustment of sliding resistances for downhill sliding, all this combined with a structurally simple model. The runners permit forward movement in the skating step, sliding on deep snow being more easily possible than when cross-country skis are used, because of the large surface. In addition, there are in this case no long ski ends to cause an obstruction when the skating step is performed. Thus the subject of this invention is ideally suited for walking and cross-country skiing in virtually all conditions of snow and terrain.
Patent DE-3815908-A1 (DE)
Title: Method for preserving the anonymity of a calling subscriber in communications switching systems
Inventor: THEIS HARALD DIPL ING
IPC: H04M1/57
Filed: 1988-05-10
Abstract: In communications switching systems which can transmit data identifying a calling subscriber to the terminal of a called subscriber in order to display it there, a calling subscriber is intended to be able to decide for himself whether or not the data should reach the called station. By means of a special operating procedure on the terminal of a calling subscriber, a code is formed and initially stored in the terminal. When the connection line is seized in an outgoing direction, this code is transmitted to the exchange before dialling is completed and with it the forwarding of data identifying the calling subscriber to the called terminal is prevented. The forwarding of data to the called terminal can even be prevented if a call diversion takes place. The operating procedures required to activate this facility in different variants can also be carried out from a different terminal or from a central operator's position. A calling subscriber can decide for himself in which instances his anonymity should be preserved. The facility can be activated on a connection-related and/or time-dependent basis.
Patent DE-3819825-A1 (DE)
Title: Motor drive device
Inventor: DREINHOFF KARL-HEINZ DIPL ING
IPC: H02P8/22
Filed: 1988-06-08
Abstract: In the case of motor drive devices having a stepping motor, it is known for different stepping grid sizes to be implemented by the stepping motor optionally being selected to the full-step mode or the partial-step mode (half steps, quarter steps etc.). In this case, the fact that the drive force emitted by the stepping motor, or its torque, is less in the partial-stepping mode than in the full-stepping mode has a disadvantageous effect. In order to obtain sufficiently high drive forces in both the full-stepping mode and in the partial-stepping mode of the stepping motor, an additional drive unit (2), for example a DC motor, which emits a uniform drive force is mechanically coupled to the stepping motor (1), which additional drive unit (2) assists the movement sequence predetermined by the stepping motor (1). <IMAGE>

Title: Hydraulic brake system with brake slip and traction control
Inventor: OCVIRK NORBERT
IPC: B60T13/68
Filed: 1988-11-03
Abstract: A brake system is demonstrated, in which both traction control and brake slip control are possible. In brake slip control the pressure is controlled by switching over of the valve 19, only those wheel brakes at any one time being connected to a brake master cylinder by switching of the valves 15', 15'', 17', 17'', which are to assume the pressure change in the brake master cylinder. During traction control, the pressure is controlled by means of the pairs of valves 15', 36 and 17', 35. The pressure is built up by the supply of pressure medium from the pump and pressure is reduced by release of pressure medium from the wheel brake into the reservoir 26 by way of the brake master cylinder chambers 28, 29.   <IMAGE>
