Title: Direct evaporative-cooling system for power semiconductors
Inventor: HAHN KURT
IPC: H01L23/40
Filed: 1983-12-14
Abstract: For the purpose of direct evaporative cooling, power semiconductors (1) are pushed into a container which is designed as a cylindrical single-layer metal bellows (18) and contains the evaporative cooling liquid and in which one of the end-face closure lids (8, 9) providing a vacuumtight seal has bushings (5) for electrically connecting the power semiconductor (1). Such a system should be designed so as to be readily assembled and it should meet high dynamic loads such as those which occur in a vehicle. For this purpose, the power semiconductors (1), along with the associated wiring components (12, 13, 14), are clamped by means of tie bolts (11) as an electrically completely interconnected unit between one closure lid (8) which incorporates the electrical bushings (5) and is composed of metal, and a centring plate (3) resting on the inside wall of the metal bellows (18). <IMAGE>

Title: Method for producing a device for heating fluids, and a corresponding device
Inventor: KITT RUDI
IPC: H05B3/50
Filed: 1983-12-17
Abstract: In the case of devices which consist of tubular heating elements and tubes which carry fluid, for heating fluids, as in the case of drinks preparation machines, the problem arises of connecting the tube which carries the fluid and the tubular heating body in a manner which on the one hand is simple from the production-engineering point of view and on the other hand ensures reliable heat transfer from the tubular heating element to the tube carrying the fluid. In order to overcome this problem, a method is proposed for producing a device (1) which has a tubular heating element (11) and a tube (2, 3) carrying fluid, according to which method a longitudinal projection (4), which extends tangentially from the tube (2) which is constructed as a profiled tube, is cut into flaps (6), which taper outwards from the tubular body (3), the tube (2, 3) is bent in its longitudinal main part until adjacent edges (7, 8) of the flaps (6) come to rest on one another, the tubular heating element (11), which is bent in a corresponding manner, is placed onto the flaps (6) and soldered thereto. A device for heating fluids, which has a tubular heating element (11) and a tube (6) carrying fluid, is designed in such a way that the tube (2) carrying fluid, is constructed as a profiled tube having flaps (6) which extend out on the sides, the flaps (6) taper in a trapezoidal shape from the tubular heating element (3) towards their ends, and are firmly connected by means of a part of their flat sides to the tubular heating element (11). <IMAGE>

Title: Current limiting arrangement in the form of a disc
Inventor: GRIMSIC BRANISLAV
IPC: H01C7/04
Filed: 1984-01-30
Abstract: The invention relates to a current limiting arrangement which is in the form of a disc, and is thin, by means of which the energy supplied to a load, for example an electrical incandescent lamp, is reduced, which prevents current surges occurring during switching on and off, and in consequence increases the life of the load. The arrangement consists of a flat resistor element, in the form of a disc, which is arranged in the opening of a perforated insulating-body disc and is electrically connected to two metal plates which are bonded onto the insulating body on both sides. The arrangement can be inserted into the socket of an incandescent lamp without technical modifications, and can thus be connected into the circuit of the incandescent lamp.

Title: Vehicle headlight
Inventor: FEYERABEND FRANZ DIPL ING
IPC: B60Q1/068
Filed: 1984-08-07
Abstract: The invention relates to a vehicle headlight with a reflector which can be swivelled by manual adjustment about two axes which are perpendicular to one another. The manual adjustment device consists of two adjustment screws whose axes of rotation extend parallel to one another and of a handle which can be displaced into two adjustment positions and has a common axis of rotation with one adjustment screw. In one adjustment position of the handle, the reflector can be swivelled in the horizontal direction about a vertical axis. In the other adjustment position, two gearwheels engage with the adjustment screws. Here, the axes of rotation of the two adjustment screws run in opposition to one another. This opposing movement is compensated by means of a deflection lever which is swivellably mounted on the housing, i.e. the two manually adjustable points move in one direction. The reflector is swivelled in the vertical direction about the horizontal axis which originates from a point formed by an adjustment element of a beam width control system. During the swivelling of the reflector by the adjustment element, the two manually adjustable points form the horizontal swivel axis.

Title: Pump for delivering a liquid or viscous medium
Inventor: MUELLER-PETTENPOHL GERHARD DIP
IPC: F04F1/08
Filed: 1984-09-04
Abstract: The invention relates to a pump for delivering a liquid or viscous medium, having a pumping chamber which, at its bottom, has an inlet orifice which can be shut off by a non-return valve, while, connected to the upper region, there are a discharge pipe and a line optionally serving for feeding in or ducting off a gas. In the case of a known valve, the multiway valve serving for appropriate switchover is disposed at a long distance from the pumping chamber. As a result, the efficiency and the performance of the pump are decisively reduced. In contrast, this drawback is overcome in the pump according to the invention by the multiway valve being disposed in the upper region of the pumping chamber or at least in the immediate vicinity of the pumping chamber outside the latter. The pressure swing required in each case then essentially takes place only in a volume which at the same time corresponds to the deliverable volume.

Title: Switching system for hot-water supplies
Inventor: KUMPA REINHOLD
IPC: F24D19/10
Filed: 1985-02-15
Abstract: A switching system for the interruption of circulation systems for hot-water supplies consists of the combination of a flow switch 5 which is controlled by the flow-through of the hot water and which switches on the circulation pump 3 of the circulation system on opening of a hot-water tapping point 2, with a time switch A which switches off the circulation system after an adjustable length of time. When a tapping point in the hot-water system is opened, the flow switch in the hot-water line is flowed through and switches on the circulation pump. After a previously adjusted time, the timer switches off the circulation pump again. As a result, considerably shorter circulation times of the hot water are obtained, as a result of which a considerable saving of heat energy and electricity arises.   <IMAGE>

Title: Process for the preparation of dry vinyl chloride suspension polymers
Inventor: MIELKE INGOLF DR
IPC: C08F2/20
Filed: 1985-02-15
Abstract: A process is described for the preparation of dry vinyl chloride polymers in which the polymerisation is carried out in aqueous suspension with addition of a water-soluble alkaline compound when the vinyl chloride conversion has reached from 10 to 70 % by weight, based on the vinyl chloride employed. After the residual monomers have been removed, the majority of the water has been decanted off and after conventional brief drying in an air-lift dryer, subsequent drying is carried out in a warmed stream of gas at from 35 to 90 DEG C for from 5 to 45 minutes. The extended subsequent drying lasting from 1 to 3 hours which is otherwise conventional is thus unnecessary.
Patent DE-3516182-A1 (DE)
Title: Vapour-tight tank for liquids of variable vapour pressure
Inventor: WITTENBORN WOLFRAM
IPC: B60K15/03
Filed: 1985-05-06
Abstract: In order to prevent vapour escaping from a tank for liquids of variable vapour pressure, said tank is designed without "venting" as a bellows made of flexible film, specifically in such a way that the vapour-air mixture above the liquid always takes up only a very small part (</= 2%) of the capacity. As a result, the change in volume of the tank which is possible due to the flexibility when the vapour pressure of the liquid changes is also small and thus unproblematic because a small relative change in the tank volume already constitutes a large relative change of the vapour-air volume and can change the partial pressure of the air therein so greatly that the change in the partial pressure of the vapour is compensated. <IMAGE>
Patent DE-3522186-A1 (DE)
Inventor: JAHN HELMUT
IPC: G01N15/00
Filed: 1985-06-21
Abstract: The deformability measurement chamber is subdivided by a foil into two chamber spaces. The foil has a passage opening, the diameter of which is smaller than the diameter, at rest, of a red blood corpuscle. A static pressure gradient exists between the two chamber spaces, so that a flow takes place from one chamber space to the other. In the region of the passage opening there is situated on each side of the foil an electrode, which is connected to an alternating voltage source. In order to achieve a measurement signal which is approximately one order of magnitude greater, at a given alternating voltage frequency, a current-measuring operational amplifier is disposed in the connecton of one electrode to the voltage source.

Title: Phase-gating controller for limiting switching-on currents
Inventor: HAENSEL GERNOT
IPC: H02M5/257
Filed: 1985-09-19
Abstract: A phase-gating controller for limiting switching-on currents in loads which are supplied with AC voltage contains a controllable power semiconductor which is connected in series with the load. The control electrode of said power semiconductor is driven via a triggering circuit, the phase angle of the triggering pulse being regulated (by means of a timing circuit which controls the triggering circuit) gradually from the conducting period of zero to the maximum conducting period. In order that this phase-gating controller can also be arranged separately from the load and can be triggered without any additional control line, a storage circuit is connected to the input of the timing circuit, the input of which storage circuit is connected in parallel with the power connections of the controllable semiconductor. The storage circuit is set by the voltage drop on the power semiconductor and remains in the set state only during the time when the load is operating.
