Title: Device for monitoring an electric heating element in a catalytic converter of a motor vehicle
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: F01N3/28
Filed: 1993-10-22
Abstract: The invention relates to a device for monitoring a heating element (102) in a catalytic converter (100) of a motor vehicle and to a method in which the device is used. The heating element (102) has two terminals (A, B) and a centre tap (C). The supply voltage (UBatt) is applied to the two terminals (A, B) and by means of the voltage (UC) present at the centre tap (C) it is assessed whether the heating element (102) is operating correctly. The heating element (102) then operates correctly if the voltage (UC) present at the centre tap (C) deviates from half the supply voltage (UBatt) by a tolerance value (dU) at maximum. In addition, the reduction in the supply voltage (UBatt) caused by the loading with the heating element (102) can also be taken into account. The voltage (UC) present at the centre tap (C) can also be used to assess the switched position of a switch (104) with which the supply of current to the heating element (102) can be interrupted. <IMAGE>

Title: Towing device
Inventor: ROSENKE ULRICH
IPC: B64F1/10
Filed: 1993-10-22
Abstract: As Figure 1 shows, the invention relates to a towing device for allowing a payload to rise, and hauling it down, in a manner which can be influenced, which payload is attached to a towing supporting body, which is self-supporting in the air, and has a passive behaviour. The invention which is specified in the claims is based on the problem of providing a towing device which makes it possible to tow through the air a towed towing supporting body, which has sufficient lift even at towing speeds from 12 km/h and has a stable flight characteristic, and which furthermore makes it possible to control the towed supporting body from the towing aircraft. This problem is solved by a towing device which is characterised in that a drive unit (11) is provided centrally on a rotatable platform (1), winches (2) are arranged in pairs in each case on the left and right, in that a cable guiding gantry (3) having cable guiding rollers (3b) is mounted over the drive unit and the winches (2), in that a common control stand (4) and a cable clamp (5) for each towing cable (6) are provided in front of the drive unit (11) for the purpose of controlling the platform (1) and the winches (2). The towing device is suitable in particular for towed operation of towed gliders from a water-borne vessel, land-based vehicle or an aircraft which hovers at low altitudes and/or above the surface of the earth or water, in order to move a payload (people) to a flying altitude. <IMAGE>

IPC: F16H39/16
Filed: 1994-07-09
Abstract: The housing of the pump (3) and/or the motor (6) is washed by at least a part oil flow from a further pump (9,12), which is part of the hydraulic circuit of the appliance. After the oil flow has passed through the housing, its temperature is reduced before it returns to the oil tank (18).

Patent DE-4428208-A1 (DE)
Title: System for recognising liquid shortage in coolant tank
Inventor: DEUSEN NORBERT DR
IPC: F01P11/18
Filed: 1994-08-09
Abstract: The system incorporates a liquid tank (13) and supply pump (11). The supply line (12) from the pump leads to the bottom of the coolant tank. An overflow pipe (14) determines the level of liquid in the tank. A return line (15) is connected to the tank at the same position as the supply line (12). The supply line and the return line are so dimensioned, that more liquid flows into the tank from the supply line than can flow from the tank through the return line. Alternatively, the return line incorporates an arrangement which prevents flow from the tank as long as coolant is being pumped into the tank. Continuous low level is indicated by sensors.

Title: Method for the drawing of reinforcing-steel meshes into turning systems and apparatus for carrying out the method
Inventor: VOIGT MICHAEL
IPC: B65G57/081
Filed: 1994-10-15
Abstract: In a method for the drawing of reinforcing-steel meshes into turning and stacking systems, the reinforcing-steel mesh is advantageously raised centrally in the transverse direction, being grasped by means of a gripper, and is fed linearly to the take-off position by the turning apparatus. Provision is made for the drawing-in apparatus to work above the mesh plane and not to need to be pivoted out of the working position. As a result of the arrangement of the gripping apparatus on the linear axis, a very high speed of movement can be achieved, particularly in the idle stroke, and the reinforcing-steel mesh is positioned exactly in the correct position without outer stops. As a result of the high speed of movement, the distance between the welding machine and mesh turning and stacking apparatus, the said distance serving as a buffer in conventional apparatuses, can be relatively small. <IMAGE>

Inventor: DEUTSCHMANN HERBERT
IPC: F02B37/02
Filed: 1987-07-03
Abstract: Système de fixation des canalisations de gaz d'échappement (6), qui sont agencées dans un espace (2) étanche auxdits gaz et servent à acheminer les gaz de combustion depuis les orifices de sortie de la culasse (9) jusqu'au collecteur d'échappement (5). En raison des sollicitations thermiques élevées que subissent les canalisations d'échappement (6) qui ne sont pas refroidies dans l'espace (2) étanche aux gaz, la fixation est conçue de manière à ce qu'il ne puisse s'exercer aucune contrainte de réaction consécutive à une déformation due à la température. Ainsi, les brides (8) assemblées avec les canalisations d'échappement (6) sont fixées en un seul emplacement périphérique respectivement. Ce mode de fixation en un point permet une dilatation radiale et axiale, sans contrainte de réaction, des canalisations d'échappement (6) soumises à des sollicitations thermiques. Chaque canalisation est vissée, au moyen de vis de fixation (7), dans la région des extrémités côté culasse (9) de préférence sur cette dernière ou sur les parois des éléments constituant l'espace étanche aux gaz d'échappement. La fixation par vis est plus fiable et procure un gain de place.
