Title: Safety switching device for motor vehicles with engine-dependent tailgate
Inventor: VOELKEL GUENTER
IPC: B60K28/10
Filed: 1988-12-22
Abstract: The invention relates to motor vehicle technology. The field of application is motor vehicles, agricultural machinery and mobile working machinery which are equipped with an engine-dependent tailgate and a deactivation device according to ECE 18. The essential features of the invention consist in the fact that a closed circuit switch for the tailgate is arranged between the ignition starter steering lock and a directional control solenoid valve which is assigned to switching off the engine, which closed circuit switch is connected to a relay and can be activated via the reversing light switch or the starter protection switch. The magnet of the directional control valve is in the first place actuated directly by the ignition starter steering lock and in another position of the ignition starter steering lock the magnet is actuated via the closed circuit switch of the tailgate when in the closed state. The actuation is interrupted by the relay when the reversing light switch or the starter protection switch is closed. The switches are prevented from influencing one another by diodes which are connected downstream of each of these switches. <IMAGE>

Title: Writing instrument
Inventor: WABNEGGER JOHANN
IPC: B43K29/00
Filed: 1989-03-20
Abstract: A writing instrument is proposed, such as a ballpoint pen, a fibre-tip pen, a pencil or the like, which is connected via a cord-like or strip-like connecting element (16) to a retaining element, the retaining element having a housing (10) with a winding device (13, 14) for the connecting element (16) arranged therein. For use, the writing instrument merely needs to be drawn away from the retaining element, with the connecting element unwinding, the writing instrument subsequently adopting its original position again as a result of the winding-up process. As a result, loss of the writing instrument is prevented, the connecting element not having a disruptive effect, even when of relatively long design, as a result of the wound-up state and a compact device being created. <IMAGE>
Patent DE-3909176-A1 (DE)
Title: Pressure valve device for a piston compressor
Inventor: HEGER WERNER ING GRAD
IPC: F04B39/12
Filed: 1989-03-21
Abstract: In previously known devices, cooling of the conveyed air by cooling ribs reaching into the pressure space of the compressor has been the aim. This solution has the disadvantage that the cooling process can only begin when the conveyed air has already left the region of the highest temperature, namely the pressure valve region, and only then strikes the cooling ribs. By means of the novel device, the cooling process is to begin already in the region where the heat arises, i.e. in the region of the pressure valve, in order thus to achieve an improved cooling capacity. The valve trap (8) of the pressure valve device has a rib-like elevation (9), by means of which it is possible to enable heat removal already at the place where the heat arises, namely directly in the region of the pressure valve (5, 7). The device is suitable for all compressors in which air needs to be conveyed out of a compression space (2) via a pressure valve (5, 7). <IMAGE>
Patent DE-3910242-A1 (DE)
Title: Method and device for measuring or monitoring the condition of a liquid
Inventor: KLEIN HANS-CHRISTOF
IPC: G01N25/08
Filed: 1989-03-30
Abstract: For measuring or monitoring the condition, the boiling point, the thermal capacity or the thermal margin of a liquid, especially a brake fluid, a sample of the liquid to be examined is enclosed in a measuring chamber (2, 16, 24, 30) which has a movable wall in the form of the end face (5', 17') of a piston (5, 17, 26), a diaphragm (29, 29') or the like. By means of the action of force on this movable wall, a reduced pressure is generated in the measuring chamber (2, 16, 24, 30), which reduces the boiling point of the liquid to be examined and which leads to an expansion of the volume of the measuring chamber (2, 16, 24, 30) only when the liquid is heated to the reduced boiling point. The expansion of the measuring chamber is signalled and serves for the quality assessment of the brake fluid or as a measure for determining the so-called thermal margin. <IMAGE>

Filed: 1989-05-18
Abstract: A semiconductor diode (9) has an I-V characteristic controlled by light (4) input into a barrier layer (3) which is pref. a pn-junction between materials with the same or different bandgaps. Use of the semiconductor diode for reducing the steepness of the characteristic and for increasing the steepness of the characteristic e.g. rectification of a.c. signals.
