Patent DE-3825273-A1 (DE)
Title: Bobbin-transport device with a projecting mandrel
Inventor: MUENNEKEHOFF GERD
IPC: B65H67/06
Filed: 1988-07-26
Abstract: In known bobbin-transport devices, the bobbins have to be removed from these and loaded onto other transport systems, for which purpose an axially movable pushing-off device is to be provided for each bobbin mandrel, in order to push the bobbin off the mandrel and onto the receiving mandrel of another transport system. The new bobbin-transport device is to allow a simpler transfer of the bobbins to another system. In the new bobbin-transport device, the bobbin mandrel is a U-profile open at the top. A receiving mandrel of the receiving system can move into the free interior of the mandrel seated in the tube and receive the bobbin by stripping off from the mandrel. Moreover, empty tubes can also be deposited on the flanks of the mandrel. The device can be developed by combining the bobbin-transport device with a further transport system and a tube-transport system, if appropriate integrated in the latter.

Title: Method for producing an aggregate for building materials
Inventor: HANNES KLAUS DIPL ING DR
IPC: C04B2/06
Filed: 1988-08-20
Abstract: In the method, free lime present in ash-laden flue gases is already slaked in the flue gas duct in order to decrease the content of free lime in the filter ash. For the slaking process, water is injected finely divided into the hot flue gas stream upstream of the electrostatic precipitator. Calcium oxide is converted to calcium hydroxide. At the same time, ammonium salts can be decomposed basically.
Patent DE-3831621-A1 (DE)
Title: Automatic cooking pot
IPC: A47J27/62
Filed: 1988-09-17
Abstract: To produce an automatic preserving apparatus having an electrical heating device, an adjustable temperature controller, a time switch which controls the preserving time and switches off the heating device after the cooking time has expired, and a time switch starter which starts the time switch when the preselected temperature has been reached and has an electrical switch which is directly in the circuit of the electrical drive, which apparatus permits a particularly cost-advantageous production in conjunction with high precision, it is proposed that the time switch starter (5) is an electrical follow-up switch which closes the switch (6) and has a thermal delay element, that the delay element is coupled to the temperature controller (2) in such a manner that, when the preselected temperature is reached, the switching contact of the controller (2) connects the delay element of the follow-up switch to the circuit and thus triggers the start signal for the time switch (3), and that the delay time of the delay element is larger than the clock time of the temperature controller (2) for maintaining the preselected temperature. <IMAGE>

Title: Wheel suspension for vehicles with variable ground clearance
Inventor: MATSCHINSKY WOLFGANG
IPC: B60G17/00
Filed: 1988-12-23
Abstract: In known wheel suspensions for vehicles with variable ground clearance the wheel suspension together with the suspension is adjusted in relation to the vehicle. This results in unfavourable kinematic conditions in the case of independent wheel suspensions and in problems with the bending angles on the drive shafts in the case of driven wheels. The new wheel suspension is intended to avoid the said disadvantages. For this purpose an adjusting mechanism (31, 40) is connected to the wheel carrier (3), so that with the adjusting movement performed by an actuating device (20) the wheel carrier (3) remains in its position and the wheel axle (7) adjusts its position in a vertical direction. The wheel suspension is suitable for off-the-road vehicles with all-wheel drive. <IMAGE>

Abstract: In a lift truck, preferably a shaft-steered traveling lift truck with a drive unit (3) pre-tensioned by spring loading in the vertical direction, the drive unit is hinged, adjustably in height, by linkage parallelogram suspension (41, 42, 44) on a chassis part (1) of the lift truck which cannot be raised. To continuously adjust the drive wheel pressure to the useful load conditions, at least one lifting cylinder (45) of the working hydraulic system for the low lift (basic lift is arranged directly between a chassis part (49) that can be raised and the linkage parallelogram suspension (41, 42, 44), and its lower end is mounted in a horizontal transverse linkage (42). The support force of the lifting cylinder (45), which opposes the lifting force, is broken down according to a leverage ratio of lever (47) to lever (48) one force component is absorbed by the chassis part (1) that cannot be raised, and the other force component is transmitted directly to a drive wheel 5 of the drive unit 3 via a lever arm (47) in order to thus maintain the necessary driving and braking torque. In order for the drive unit (3) to be able to compensate for unevennesses of the ground even when the lift truck has been lowered, a lifting piston (50) of the lifting cylinder (45) has a free running segment (52) designed as residual stroke.
