Title: Cantilevered tarpaulin bows which can be folded to the side and are intended for vehicles
Inventor: WOELKE ERHARD
IPC: B60J7/10
Filed: 1982-12-20
Abstract: The tarpaulin bows are particularly suitable for vehicles with tipping platforms. Bulk materials such as hot tar, mortar inter alia, which are to be covered are frequently transported by said vehicles. When loading said vehicles (in particular from silos), the entire vehicle floor must be free of struts or bows. When unloading, the bows may be left (using the cable pulls) at different heights above the load. As a result, it is possible to open one side in order to tip or shovel out the load (unobstructed by the bows). Using the rod, the bows may be completely folded away (in just a few seconds), or after loading may be pulled over the load on the vehicle floor.

Patent DE-3347256-A1 (DE)
Title: Method and device for implementing the method for the operation of a hydrodynamic torque converter with lockup clutch in the drive of a tractor vehicle, especially an agricultural tractor
Inventor: GOERNER FRIEDRICH
IPC: B60K25/02
Filed: 1983-12-28
Abstract: Hydrodynamic torque converters are generally used in the travel drive of vehicles purely as starting converters, since their great operating slip causes considerable losses. In order to avoid these losses torque converters of this type are bypassed by a clutch. The lockup clutch is usually switched on and off as a function of the speed of rotation of the turbine wheel of the torque converter. In tractor vehicles which have an auxiliary shaft driven by the pump impeller of the converter for driving working implements, difficulties may result from this with regard to correct functioning of the working implement, if the working speed of the latter drops due to a transient overload. In order to prevent these difficulties, the lockup clutch can also be opened if the speed of rotation falls below a predetermined minimum working speed of the switched-on power take-off shaft and closed if a predetermined maximum working speed is exceeded. <IMAGE>

Title: Electronic connection between microprocessor systems, and microcomputer subsystems which operate in the "minimum mode" and microprocessors which operate in the "maximum mode"
Inventor: BULCKE FRED P P
IPC: G06F15/17
Filed: 1984-03-19
Abstract: The connection (3) makes it possible that microprocessors (7) of the 8088 and 8086 type, which are connected in the "maximum mode", can now also be used in microprocessor systems (10) which are connected in the "minimum mode" so that the numeric processor (8) of the 8087 type can also be used in such systems. The carrier (9) is mounted with its terminals (2) in the socket (1) or the holder of the system. The microprocessor (7), which is connected in the "maximum mode" can communicate with the system interface (1) of the microprocessor system through the connection (3). Due to the fact that the microprocessor (7) itself operates in the "maximum mode" but the connection (3) emulates the "minimum mode", the numeric processor (8) can be integrated in the overall system (10). The connection (3) consists of two essential parts, namely the stop request logic (4) and the logic for the status signals (5). The logic is very fast so that no wait cycles are necessary at all. As a result, the basic speed of the system is preserved if the numeric processor (8) is not used. The stop request logic (4) consists of a circuit which is constructed of flip flops (11), gates (12) and resistors (13). The stop request logic generates the request (RQ) signal from the signals HOLD and CLK which come from the microprocessor system (10). From the ... Original abstract incomplete. <IMAGE>
