Title: Method for determining hypotheses or faults, taking into account uncertain features and using conditional feature probabilities
Inventor: LIEBEL PETER ING GRAD
IPC: G06F17/18
Filed: 1987-04-24
Abstract: In summary, the method is characterised by the use of the so-called L set for the calculation of hypothesis probabilities. The product probabilities of the said set are replaced by conditional probabilities in any desired fashion, using the multiplication set of mathematical statistics. The conditional probabilities which are then necessary are acquired approximately from suitably arranged random samples. Such random samples also provide confidence intervals, and thus error data for the conditional probabilities. Determination of the relative greatest error of the hypothesis probabilities is based on the use of the calculation formula which, for A uncertain features, contains 2<A> summands in the numerator and in the denominator, each of which summands consists of a number of probabilities linked by multiplication. Each probability value can be derived from a separate random sample, so that their errors can be considered to be mutually independent. Taking this unfavourable assumption into account, the error calculation is carried out according to a known procedure.

Title: Gripper for industrial robot
Inventor: SCHANZ RAINER DIPL ING
IPC: B25J15/04
Filed: 1987-10-09
Abstract: In order to be able securely to grip parts of different thickness using a parallel gripper with two gripper jaws, with relatively little outlay and with the gripper being light in weight so as not to load the tool arm of the industrial robot excessively, one of the two gripper jaws is directly connected to the tool arm of the industrial robot. A pantograph and further articulated levers are arranged between the two gripper jaws pivotably on a longitudinal drive in such a way that when the gripper jaws are moved towards or away from one another they do so in rectilinear and perpendicular fashion and thus remain mutually parallel. At the same time, as the distance between the two gripper jaws increases, the force of the gripper rises. By appropriate arrangement of the bearings of the pantographs and of the articulated levers, tilting and displacement of the gripper jaws while gripping parts are avoided.

Title: Process for fastening insulating bodies of a firm, fibrous consistency
Inventor: RECK ALFRED
IPC: F17C13/00
Filed: 1988-03-15
Abstract: The invention specifies a time-saving process for mounting insulations comprising fibre/ceramic bodies (5, 8) in the case of which process only low requirements are made on the accuracy of the fit of the parts. Fastened on one wall (1) are first pins (2), onto which (if appropriate with the interposition of a fibre mat (4)) first of all a first insulating body (5) is pressed, the pins pressing into the same. Thereafter, second pins, with at least two tips extending parallel to the wall (1), are pressed in at the free edge of the body (5) and fastened on the wall (1). The next insulating body (8) can then be pressed onto these pins, this resulting in a permanent fastening which is protected against the effect of high or extremely low temperatures. By virtue of a surface texturing (3) of the pins, a micro form fit can be achieved. A groove-and-tongue connection (9, 10) assists the holding-together of the insulation. Any free borders of the insulation can be retained in rails (6). <IMAGE>

Title: Electrical resistor component
Inventor: RUSTEMEYER GERHARD
IPC: B60H1/00
Filed: 1988-06-21
Abstract: Such series resistors can, in the event of malfunction, lead to high temperatures, with the result that fusable cutouts or MICRO thermal fuses are installed in the circuit of the resistor, these breaking the circuit when a particular temperature is reached. In order greatly to accelerate the response of a MICRO thermal fuse (MTS), one end of the main resistor (2) is connected to one terminal wire (7) of the MTS via an auxiliary resistor in the form of a resistance wire or strip (8). In the event of malfunction (locking of a motor) said wire of strip heats up rapidly and quickly releases this heat to the MTS so that it immediately breaks the circuit. A fusable cutout is not necessary. The resistor component is used principally as a series resistor for fans (blowers) or air-conditioning systems of motor vehicles. <IMAGE>

Title: Process and device for dewatering sludge, in particular mud from rivers, harbours or the like
Inventor: KULLE HEINZ DIPL ING
IPC: C02F11/12
Filed: 1988-08-25
Abstract: It is known to divide the sludge pre-dewatered in centrifuges, sieve belt presses or the like into pellet-shaped lumps or mouldings, to encase the sludge mouldings with a layer of pulverulent drainage material such as ash and then to compress a bulk of these mouldings in a press and thus to give them a secondary dewatering, as a result of which high degrees of sludge dewatering are achieved. This known dewatering method with pressing of sludge lumps is efficient, in particular, if the sludge has a high content of compressible solids, which, for example, is the case with mud. In order, in the known dewatering process, to be able to produce the drainage material as simply as possible, according to the invention it is proposed that a fine sand fraction (15) is separated off from the sludge or mud (12) in a classifier such as a hydrocyclone (14), which fine sand fraction, if appropriate after dewatering (22) thereof, is used as fine-grained drainage material (23) for encasing the mud lumps. <IMAGE>
Patent DE-3836554-A1 (DE)
Title: Plant for using buoyancy force
Inventor: GEISS KLAUS
IPC: F03B17/02
Filed: 1988-10-27
Abstract: A plant comprises a pressure container which tapers at the top into a vertical hollow cylinder upon which is mounted a funnel. In the pressure container there is an air-filled sphere. Leading through the centre of the sphere and connected to the latter is likewise a vertical hollow cylinder, the bottom of which closes a valve in the present [lacuna]. If the outlet opening is opened at the top of the pressure container, the potential energy becomes kinetic energy, as a result of which the filled hollow cylinder, when the bottom valve is closed, drops with the air-filled sphere connected at the bottom, and presses the water located thereabove. In this case, the hollow cylinder dips into the pressure container and displaces water which flows out at the outlet opening. When the outlet opening and the water feed are closed, the bottom valve of the hollow cylinder is opened, the air-filled sphere obtaining buoyancy and moving upwards with the hollow cylinder. In this arrangement, a toothed rack attached thereto drives the transmission with generator located at the top, by means of which the buoyancy force is converted into electrical energy. If a turbine is mounted on the outlet opening at a sufficient height, the outlet and the water feed always remain open.
