Patent DE-3729304-A1 (DE)
Title: Corrosion indicator
Inventor: BONSELS WILLY
IPC: C23F13/04
Filed: 1987-09-02
Abstract: Electrochemical corrosion often occurs in not readily accessible spaces or plants where it is not discovered visually early enough to prevent damage. Visual monitoring, moreover, is often impossible in installations while these are running. To overcome this problem, the invention provides a device for detecting an electrochemical reaction in such an object to be monitored. Two or more measuring electrodes are arranged which are located in the object to be monitored and whose materials are selected in such a way that they have a differential potential between their normal potentials. If a current starts to flow between these measuring electrodes, this generates a signal which indicates the start or the impending start of an electrochemical corrosion in the object to be monitored. <IMAGE>

Title: Passenger car with hydrodynamic clutch and parking brake
Inventor: MATHIAK DETLEF
IPC: F16D47/06
Filed: 1987-11-07
Abstract: Passenger car with hydrodynamic clutch and parking brake. The pump wheel and the turbine wheel of the hydrodynamic clutch can be coupled via a parking brake which is subjected to the working fluid of the hydrodynamic clutch, the said parking brake having a ratchet wheel which is coupled to the pump wheel by means of friction linings and a single-arm ratchet lever which can be rotated with the turbine wheel and is pivotably mounted and, in its engagement position in which it engages in the ratchet wheel, is arranged essentially tangentially to the said ratchet wheel and points with its free end in the direction of rotation of the turbine wheel and during its rotation with the turbine wheel is lifted out of the ratchet wheel under the effect of centrifugal force. In order to ensure reliable lifting out of the ratchet lever from the ratchet wheel in order to spare the frictional linings of the parking brake even when the motor vehicle is being towed away at a low ambient temperature and therefore when the working fluid is more viscous, the ratchet lever is designed in such a way that when the turbine wheel is driven via the clutch drive with the working fluid still stationary an additional lifting-out moment which acts on the ratchet lever is produced from the expulsion resistance of the working fluid which counteracts the ratchet lever during its rotation. <IMAGE>

Patent DE-3801979-A1 (DE)
Title: Push-button switch
Inventor: ROESL WOLFGANG
IPC: H01H3/12
Filed: 1988-01-23
Abstract: Push-button switches, which are provided, for example, for installation in radio sets, have a snapping effect which can be sensed when they are pressed in order to provide the person operating them with feedback that contact has been made. Radio sets must be operable even in difficult conditions, and it is intended that the snap-action effect remain detectable. The problem exists, particularly in winter, of operating the radio set wearing gloves. The length to width ratio of the push button to be operated is between 2:1 and 5:1. At the same time, a novel design ensures that the push button is always displaced in a straight line and the snap-action mechanism is always effective, irrespective of the point at which the pressure is applied. <IMAGE>

Title: Hydraulic antilock device for wheeled vehicles
Inventor: SABIC MILORAD DIPL ING
IPC: B60T8/40
Filed: 1988-03-26
Abstract: In the hydraulic antilock system (10) for wheeled vehicles with hydraulic brake system (11) a hydraulic shut-off element (17) in the nature of a switch is inserted in the brake line (18, 19) of each vehicle wheel. In normal braking operation the switch (17) is open. A return line (21) is provided parallel thereto, into which a switch (22) is inserted, which acts in the opposite direction to the first switch (17). The two switches (17; 22) are coupled to a first piston drive (32) acting on one side. The said piston interacts with two mechanical spring elements (35; 36). The spring element (35) acting in the same direction as the cylinder chamber (40) is rigidly supported. The spring element (36) acting in the opposite direction is supported on a double-acting second hydraulic piston drive (39). Its two cylinder chambers (41; 42) are acted upon by way of a control device (43) as a function of the operating position of the first piston drive (32). Each vehicle wheel (16) is coupled to a metering pump (55). This is directly coupled to the first piston drive (31). When, in a braking sequence, the vehicle wheel begins to slip, the pressure of the metering pump (55) rapidly diminishes. As a result, the first piston drive (32) reverses the two switches (17; 22). The brake (15) is relieved and the vehicle wheel can rotate again. The pressure of the metering pump (55) rising again causes ... Original abstract incomplete. <IMAGE>
Patent DE-3812750-A1 (DE)
Title: Container for pumpable substances having an integrated, peristaltic emptying system, driven pneumatically or hydraulically
Inventor: NAGEL KARL
IPC: B65D88/12
Filed: 1988-04-16
Abstract: The container consists of a surrounding, self-supporting casing with cutout possibilities into which individual tank batteries are introduced. A tank battery consists of a tubular vessel arranged vertically in meandering coils and simultaneously constituting a peristaltic conveying system with a pneumatic or hydraulic drive. The peristaltic system presses the vessel contents in portions to a removal point. The vessel contents come into contact only with the inside of the peristaltic system; the displacement medium also always remains separate from the storage or transporting product. The control of the peristaltic system is relatively simple. The contents of the container are protected in several ways against leakages. If a leakage should nevertheless occur, only a small portion of the contents will leak, due to the meandering coils. Since the peristaltic system conveys in any direction, no gradient is required and the position of the removal site is insignificant. The surrounding casing is not part of the actual vessel; it can also be used as a chassis.

Patent DE-3827760-A1 (DE)
Title: Wheel suspension spring strut arrangement of a motor vehicle
Inventor: OEHLERKING CONRAD DIPL ING
IPC: B60G15/06
Filed: 1988-08-16
Abstract: In a known wheel suspension spring strut arrangement the piston rod of the spring strut is articulated directly on the vehicle body by way of a rubber-elastic bearing, the elastomer element of which, under axial forces introduced into the bearing, is deformed not only in an axial direction but also in a circumferential direction, so that a rotational movement of the piston rod relative to the damper tube is superimposed on the reciprocating movement of the telescopic shock absorber, thereby reducing static friction forces due to bending moments, which might under some circumstances lead to jamming of the telescopic shock absorber. In order to improve the reduction of such static friction forces, the coil spring and the rubber-elastic bearing are arranged in such a way that the relative rotational movement is assisted, at least at the travel reversal points, by the mass moment of inertia of the coil spring. <IMAGE>
