Patent DE-3223624-A1 (DE)
Title: Heat sink for electrical components
Inventor: BRADISH ROBERT ING GRAD
IPC: H01L23/367
Filed: 1982-06-24
Abstract: The invention relates to a heat sink (4), which is preferably used as a housing cover, for electrical components which generate heat, which heat sink is provided with cooling ribs (7, 8) on both the component side and on the outer side. In this case, the ribbed surface on the component side increases the heat absorbtion, while the cooling ribs on the outer side improve the heat dissiptation to the environment. In consequence, an increase in the heat dissipation is acheived, for example via a housing cover, by improving the internal and external convection. The invention can be used for cooling electrical components. <IMAGE>

Patent DE-3237130-A1 (DE)
Title: Bellows- and -capillary viscometer
Inventor: KUSS EDUARD PROF DR
IPC: G01N11/08
Filed: 1982-10-07
Abstract: In commercial falling-sphere or capillary viscometers, the spheres have to be raised again, for example by tipping the apparatus or the measuring substance has to be sucked up in the capillary viscometer in order to repeat the measurement, it being necessary for a phase boundary (usually a liqid/gas boundary) to be present. Automatic operation and replacement of the substance within the measurement series (for instance to observe viscosity changes in a production plant) are not possible or are only possible with considerable effort. In the apparatus claimed, a thin-walled bellows is electromagnetically compressed and old substance is expelled. "Fresh substance" is then drawn in from the outside via a capillary during the free expansion of the bellows. Regardless of pressure and temperature, the bellows position determines the pressure difference across the capillary and the bellows movement determines the flow velocity. The viscosity is given by the signals obtained from a distance transducer. The small space requirement makes possible automatic measurements in high-pressure plants and flowing media, and also parallel operation of a plurality of measuring inserts.

Patent DE-3306846-A1 (DE)
Title: Drive device for moving a shut-off slide
IPC: F16K31/122
Filed: 1983-02-26
Abstract: In the starting phase of the opening movement of a shut-off slide, a greater force is necessary for breaking away than over the remaining part of the opening operation. To displace the rod (10) actuating the shut-off slide, use is made of a main piston (25) which is accommodated in a main cylinder (23). Situated in the same cylinder housing (11) as the main piston (23) is an auxiliary piston (12) which presses against a stop (33) of the rod (10). Main piston (25) and auxiliary piston (16) are acted upon together with compressed air. The lifting movement of the auxiliary piston (16) is limited by a fixed stop (36). When the auxiliary piston (16) has reached the stop (36), the main piston (25) continues the opening movement alone.   <IMAGE>

Title: Differential gear arrangement
Inventor: MUELLER ERICH
IPC: B60K17/346
Filed: 1983-03-26
Abstract: In the case of an arrangement comprising two differential gears connected in series the differential cases (5, 12) of the two differential gears (2, 4) are pivotably mounted about a common main axis. A drive wheel (13) of the first differential gear (2) is directly connected to the differential case (12) of the second differential gear (4) by way of the one drive shaft of the first differential gear (2) designed as a hollow shaft (14). One drive shaft (27) of the second differential gear (4) passes through this hollow shaft (14) and the other drive shaft (19) of the first differential gear (2) likewise designed as a hollow shaft. The first differential gear in particular may be designed either as a bevel gear, spur gear or as a planet wheel differential gear. This results in numerous possible variations with regard to the design construction, the required space and the distribution of torques, which make the use of the gear arrangement especially interesting in a small off-the-road motor vehicle with all-wheel drive (fig.1). <IMAGE>

Filed: 1983-12-24
Abstract: The process for coating substrates with metals in a reaction chamber by depositing the metals from the gas phase comprises the following process steps:   a) bonding the metals to be deposited as nuclei in one or more organometallic sandwich compounds, b) reduction of the pressure in the reaction chamber and simultaneous introduction of the sublimed organometallic compound (s) on its own or together with one or more other gaseous substances into the reaction chamber, c) liberation of the metal ions present as nuclei in the organometallic sandwich compounds by allowing the sandwich compounds to interact with an electromagnetic or corpuscular radiation in the reaction chamber, d) production of a polarising electrical or magnetic field in the reaction chamber, as a result of which the liberated metal atoms are deposited on the substrate (s) to be coated.
Patent DE-3401174-A1 (DE)
Title: Discharging conductive foreign bodies from bulk material
Inventor: EIFEL MATTHIAS DR
IPC: B07C5/36
Filed: 1984-01-14
Abstract: Metallic foreign bodies which enter the product stream seriously endanger operation in chemical production plants. A device is specified by means of which such foreign bodies can be discharged. The device consists in principle of a tubular distributor which is controlled by an inductive metal detector and has a gravity chute (1) and a side tube (5) placed against the latter. The tubular distributor is formed by a flap (7) which can be pivoted into the gravity chute (1) and extends over the entire cross-section. When in its rest position (gravity chute open), this flap (7) closes the mouth of the side tube (5) and rests against the inside of the wall of the gravity chute. In addition, when in its rest position it is pretensioned by a torsion spring (9) and fixed by an electrically controlled locking device (11, 12, 13, 14). If the metal detector detects an electrically conductive foreign body in the product stream, a signal is generated which actuates the locking device (11, 12, 13, 14). As a result of this, the pretensioned flap (7) is pivoted about an axis in such a way that it closes off the gravity chute (1) at an angle of inclination of 10 DEG  to 40 DEG . The closure time of the lock can be minimised by special dimensioning of the flap (7). <IMAGE>

Patent DE-3409934-A1 (DE)
Title: Devices working according to the injector principle and use of such devices in centrifugal pumps, turbines and in particular hydrodynamic transmissions
Inventor: INGELHEIM PETER GRAF VON
IPC: F03B15/02
Filed: 1984-03-17
Abstract: The invention relates to devices working according to the injector principle and the use of such devices in centrifugal pumps, turbines and in particular hydrodynamic transmissions (F omega ttinger fluid torque converters). Here, the cross-sectional area of the nozzle (22) in the device (20) working according to the injector principle is variable so that the pressure in front of the nozzle and the flow rate through the nozzle can be regulated. The minimum cross-sectional area of the mixing passage (3) can be changed in such a way that the pressure and/or the flow rate behind the device can be maximised. The delivery flow of a centrifugal pump (25) and the inflow into a turbine (21) can be influenced by means of such devices (20). In particular in a hydrodynamic transmission, such a device is used to split up the fluid flow through the turbine into two fluid flows at its outlet, of which the one is directed through a line (23) and the device (20) back into the turbine inlet, and the other flows through guide wheel, pump (25) and device (20) back into the turbine inlet. The advantage of this arrangement is that the fluid velocities in pump, guide wheel and return line (23) are kept low and thus the flow losses are greatly reduced. At a small speed ratio, the turbine torque thus increases compared with known F omega ttinger converters.   <IMAGE>
