Title: Torsional vibration damper
Inventor: TEBBE GERHARD DIPL ING
IPC: F16F15/129
Filed: 1986-06-02
Abstract: In a torsional vibration damper, in particular for a clutch disc of a motor vehicle, a first rotary unit has a first friction surface and a second rotary unit has a second friction-surface carrier with a second friction surface. The second friction-surface carrier is mounted movably on the second rotary unit and guided by guide means which allow it a guide play relative to the second rotary unit which deviates from the peripheral direction around the axis of rotation. In the case of frictional vibrations, the second friction-surface carrier performs a movement relative to the second rotary unit. The characteristic of the resultant friction torque between the two rotary units can be varied by the choice of guide means.

At the same time, a space for an empty pallet is formed below the receptacle. The receptacle has a recess-like space of the size of the pallets, swivelling elements, which receive the pallet to be loaded, being arranged at the opposite sides, at a distance from the floor. During the change, the empty pallet is lifted and picks up the loaded pallet. At the same time, the swivelling elements are twisted to release the passage and, after the empty pallet has passed, fall back into their initial position so that, during lowering, they serve to receive the pallets.
Patent DE-3707678-A1 (DE)
Title: Apparatus for steam tapping and drainage (dewatering) of steam pipelines with simultaneous heat delivery to heat consumers, preferably as a house station of steam-type district-heating systems
Inventor: MALY FRANZ DR ING
IPC: F24D10/00
Filed: 1987-03-10
Abstract: The described apparatus is preferably used as a heat-delivery station (house station) of steam-type district-heating systems, but also takes on the function of pipeline drainage of the supply pipelines. It is thus possible to dispense with all installations for pipeline drainage which are otherwise necessary. The system-dependent capacity of the pipeline drainage is so great that the supply pipelines can be laid horizontally or even at (almost) any gradient, with the result that the construction of the supply network is made considerably less expensive. The condensate heat can be optimally utilised in a very simple way. The apparatus makes the operation with waste condensate economical and competitive. So-called condensate shocks are completely excluded where the apparatus is employed for the method of operation using condensate recovery.
Patent DE-3710346-A1 (DE)
Title: Monorail suspension trolley
Inventor: FINZEL MANFRED DIPL ING
IPC: B66C11/06
Filed: 1987-03-28
Abstract: A monorail suspension trolley contains running gear having two parallel guard plates located at a distance from one another. The running-gear guard plates are connected to each other by two parallel, preferably cylindrical lifting beams at a distance from one another, and serve as mountings for the track wheels. In addition, an electric pulley block is mounted on the running gear. The monorail suspension trolley can be assembled with a small overall height, with otherwise unchanged design of the running gear, if a deflecting device for the hoisting tackle of the electric pulley block is located on the lifting beams, while the electric pulley block itself is flange-mounted on the side of one of the running-gear guard plates. By replacing the deflecting device with a fastening device that is also positioned on the lifting beams, a monorail suspension trolley of normal overall height is created, in which the electric pulley block hangs directly from the running gear.

Patent DE-3712139-A1 (DE)
Title: Apparatus for transporting workpieces arranged, in particular, on workpiece carriers
Inventor: MATTFELDT BERNHARD DIPL ING
IPC: B23Q7/14
Filed: 1987-04-10
Abstract: In the feeding of workpieces to processing devices for further processing or assembly, it is customary to use workpiece carriers (16). After the workpiece has been taken off, the workpiece carriers must be taken off by the continuous conveyor (10) serving to transport the latter, and be transported separately back to the starting position. The invention intends to provide an apparatus by means of which the separate returning of the workpiece carriers (16) becomes unnecessary. The invention proposes to transport the workpiece carriers (16) in a circulating manner on the continuous conveyor (10), as a consequence of which the return transport of the empty workpiece carriers (16) can take place on the lower strand (20) of the continuous conveyor (10). For this purpose the workpiece carriers (16) are produced from an elastically deformable material. The apparatus is suitable, in particular, for the discontinuous feeding of sensitive workpieces to subsequent processing stations. <IMAGE>

Title: Flow velocity measuring device
Inventor: ANDO TSUYOSHI
IPC: G01F1/38
Filed: 1987-04-22
Abstract: In a channel, which connects an inlet (12) to an outlet (14), a valve body (18) is arranged, which moves through a stroke to influence the degree of opening as a reaction to the flow velocity of a liquid. A front-back differential pressure across the valve body (18) and the stroke of the valve body (18) are determined by means of pressure sensors (24, 26) and a stroke sensor (32). The flow velocity of the liquid is calculated from the determined front-back differential pressure and the determined stroke of the valve body (18). From the front-back differential pressure and the stroke of the valve body (18) a flow coefficient is derived, in order to be able to calculate the flow velocity therefrom. If the Reynolds Number of the system has reached its maximum value, the flow coefficient is set to a constant value by means of a limit switch. This constant value is used in the calculation of the flow velocity. Furthermore the temperature of the liquid is determined, and the kinematic viscosity and the concentration of the liquid, both of which quantities are used in the calculation of the flow velocity, are corrected on the basis of the determined fluid temperature. <IMAGE>
