Patent DE-3814342-A1 (DE)
Title: Device for braking a moving body unguided in the direction of movement
Inventor: MURRENHOFF HUBERTUS DR ING
IPC: B61K7/00
Filed: 1988-04-28
Abstract: Freely moving bodies such as, for example, rolling or runaway vehicles, round packages, are normally braked by allowing the bodies to impact on a resiliently supported catching element. By this means alone the body receives a considerable shock and it is moreover necessary that the potential energy capable of being stored in the springing is larger than the kinetic energy of the body. Bodies with larger energies or velocities can be braked without pressure and shock if the catching element (6) is set into motion in the direction of motion of the body (1) by means of a catching drive (4, 5) on the approach of the body (1), in such a way that the catching element and the body reach the same position and velocity at a fixed instant. The catching element (6) is subsequently braked with dissipation of the movement energy. By means of sensors (12, 13, 31), the catching drive (4, 5) can, if necessary, be set into motion with a specific movement rule corresponding to the proximity and/or the velocity of the body. <IMAGE>

Title: Round heat exchanger, in particular for refrigerants (refrigerating media) of air conditioners
Inventor: BAUER DIETER DIPL ING
IPC: F28D1/047
Filed: 1988-05-07
Abstract: Known round heat exchangers are expensive to produce. Because of the sharp bends in the tubes, which are wound approximately in the shape of cylinders, undesirable pressure losses also occur as flow passes through and lead to a reduction in performance. According to the invention, a flat tube is wound in the shape of a helix to form a cylindrical body. Inserted into the interspaces between the individual layers of the helix are heat exchange ribs through which the second medium participating in the heat exchange can flow radially. The round heat exchanger thus constructed makes available a high heat exchange performance in conjunction with a simple mode of production and the lowest space requirement. The novel round heat exchanger is suitable, in particular, as an evaporator or condenser in air conditioners.
Patent DE-3818583-A1 (DE)
Title: Balanced support-lifting device
IPC: E21D11/40
Filed: 1988-06-01
Abstract: For roadway driving in underground mining and tunnelling, a support-lifting device is provided, by means of which a prepared support arch can in each case be moved laterally past the selective-cut heading machine and can be taken up to the face. The boom of the support-lifting device has a swivel joint which is integrated in the main frame and to which a rotary cylinder is allocated in order to mechanise the swivelling of the boom. Running parallel to the rotary cylinder is a pump cylinder which in turn is coupled crosswise to a sliding cylinder which displaces a balance weight in each case in the direction opposed to the swivelling direction of the boom. Consequently, the support-lifting device always remains balanced after the support arch is received and the boom moves into position, even when the boom projects well to the side. <IMAGE>

Patent DE-3827802-A1 (DE)
Inventor: RAMACHER ULRICH DR
IPC: H03K19/0185
Filed: 1988-08-16
Abstract: In discrete wafer scale integration, in short WSI, pre-tested chips (C1-C16) are mounted and bonded on a pre-wired wafer (W). Silicium is mainly used for the wafer substrate, since the wafer can then be economically wired by a standard multilayering process. The conductivity of such wafer microwiring forbids the use of long feed lines with long cycle times, so that intermediate drivers (Tr1-Tr4) must be used. Separate driver chips that must be located, bonded and tested besides the operating chips themselves have been used until now to solve this problem. In the proposed WSI system, the intermediate drivers are not separate chips but are implemented on the operating chips themselves.

Patent DE-3832196-A1 (DE)
Title: Tension-roller device for drive belts of rotary parts, especially of spinning-machine or twisting-machine spindles
Inventor: PATRIARCA GIOVANNI
IPC: D01H1/241
Filed: 1988-09-22
Abstract: The device according to the invention has a tension roller which is mounted so as to be rotatable about its own axis and so as to be pivotable about a pivot axis extending at right angles to the axis of rotation of the roller and to the tangential plane between the belt and the roller. Guide extensions of the belt edges are fastened to the pivotable holder of the roller. A displacement of the belt in the axial direction of the roller leads to a displacement of the guide extensions and therefore to an angular displacement of the holder of the roller which is thereby pivoted with an inclined axis of rotation and exerts on the moving belt a force which counteracts the transverse displacement, in order thereby to keep the belt in its correct path.

Patent DE-3910116-A1 (DE)
Inventor: WOESTE GUIDO DIPL ING
IPC: B60S1/08
Filed: 1989-03-29
Abstract: In a means for controlling a windscreen wiper by means of a rain sensor constructed as a piezoelectric signal transmitter, it is important to eliminate the disturbing influences acting on the signal transmitter for example due to mechanical vibrations. In order to achieve control which follows as exactly as possible the rain intensity which occurs, it is proposed to construct the rain sensor from at least two piezoelements which are electrically separated from one another and whose measurement signals are evaluated on two parallel paths and, only after this, are compared with one another. The wiper drive is then actuated in accordance with the comparison result. The invention has in fact recognised that disturbing influences usually occur in both elements in a similar manner. Thus, they are detected and not taken into consideration in the evaluation.   <IMAGE>

Title: Loop-type reactor column - circulates and mixes viscous liq. to small droplet size using static and rotating shear elements
Inventor: BURGERT HERWIG
IPC: B01J19/18
Filed: 1989-06-16
Abstract: Viscous liq. entering a reactor column to be reduced to very small droplets is forced by curved base surfaces to start a loop circulation by rising in a central tubular t insert, past a bulbous lower end of the insert. After discharge through a ring of slots round the insert head, liq. resumes its loop path down the exterior of the insert, and turns round the terminal bulbs to be further mixed in the insert with freshly arriving liq. At the downsteram end of the thicker insert the liq. is subjected to shear forces between a stator at the insert end and fins extending down from a rotor plate integral with an external drive shaft and also forming the insert cover. Droplets reduced to suitable size pass through a narrow annular gap round the insert into a collector chamber and finally an outlet. A dynamic version of the static reactor has a central feed  worm in the insert. USE - Used for homogenising milk and other processing of foodstuffs. Short drive shaft permits high speed rotation in providing shear forces.
