Patent DE-4124778-A1 (DE)
Inventor: HORN ANTON PROF DR
IPC: G01N30/46
Filed: 1991-07-26
Abstract: The invention concerns a method and apparatus for analysing agglutination reactions, the reactants being placed on a micro-column. The agglutination reaction takes place on the micro-column, preferably before the reactants have passed through the gel matrix. Agglutinated and non-agglutinated particles are preferably separated from each other by filtration accelerated by force application. The eluate containing the non-agglutinated particles is subjected to quantitative analysis after it has left the column.
Patent DE-4125044-A1 (DE)
Inventor: HILL WOLFGANG
IPC: H02K3/12
Filed: 1991-07-29
Abstract: Known flat winding layers that can be prefabricated and inserted into soft magnetic bodies insufficiently utilize the available space in the grooves and winding overhang of polyphase machines and thus increase the volume and weight of the machine. A new winding design allows high power and force densities to be obtained, thanks to the utilization of the whole available space, and are economic to produce. For that purpose, each winding layer (4d) is composed of several groups of conductors (22-24) whose number corresponds to the number of phases. The height of the groups of conductors is reduced at the points where they intersect (25-33), due to the fact that the conductors are mutually offset, and thus pass over each other inside the layer. By variably adapting the width of the conductor, the space in the winding overhang through which the magnetic flow is directed in the soft magnetic body is utilized. The space available in the winding overhangs is completely utilized thanks to double winding layers, of which each second layer mirrors the first and is offset by a pole pitch with respect to the first. The winding is suitable for motors and generators whose volume and weight can be advantageously reduced.

Title: Limiting current esp. in large sync. generator - antiphase clocking of analogue transistor switches in memory circuit simulating thermal behaviour of machine
Inventor: HAASE OTTO
IPC: H02H7/06
Filed: 1991-08-09
Abstract: Set-point values of armature and field winding currents (IG, If) are continuously adjusted in dependence on the load deduced from integration (2) of the squared current measurements. Values proportional to heat losses are stored in an electronic memory (3-5, 32, 33) which simulates heating and cooling as an exponential function. Voltage and current limit set-points are varied independently and, if the impedance of the supplied network falls, the armature current limit set-point is raised. ADVANTAGE - Load-shedding is generally avoided by use of simple analogue components in circuit which is not time-dependent.

Internally the power-lines and ground-lines are connected, via a conductive material (13), to the respective planes, which have a shape which depends on number and position of the connections. A heat dissipating layer is attached by an insulating layer (10). A resin is used to encapsulate the upper area of the die and its connections, leaving the heatsink exposed. The leadframe pref. uses an insulating film (3) to which the connections (4,14,15,16) are attached and which surrounds the die. This film has vias (3a which allow electrical contact between a connector (14,15,16) and a plane (11,12) via the material (13), which is pref. a conductive resin. The power-connections (15,16) pref. are on opposite sides of the die, to each other and at a right angle to the ground-connections (14). USE/ADVANTAGE - For large area highly integrated circuits with high heat dissipation. Leadframe combines improved heat dissipation, due to reduced resistance path to large area heatsink, with reduced power induction due to use of power-planes. Upper part is moulded, which provides mechanical stability to leads (5). Power and ground planes reduce inductance and resistance of power and ground connections to die.

Title: Cleaning and drying contaminated material - using fine fluid spray with an electrical charge to bring matter to the surface by electro=osmosis and wash it away
IPC: F26B7/00
Filed: 1992-01-29
Abstract: To dispose of hazardous matter or for drying, water treated electrolytically or by other means or other neutralising fluids with a low viscosity are directed at the surface to be treated in a fine spray. Initially the water particles are given a positive electrical charge during spraying, so that by striking each other the satd. steam pressure is exceeded without condensing the fluid. The penetration of the fluid into the contaminated material, and the mixing action with the matter to be removed, is supported by an electro-osmosis effect and accelerated. After satn., the polarity of the electrical field is reversed and the fluid feed is slowly throttled until an electrical field is developed between the hazardous matter and the negatively-charged spray head. This brings the hazardous matter to the surface for removal and disposal. USE/ADVANTAGE - The method is used for cleaning surfaces, such as in wood drying chambers, where the cell water is forced out through high temps.. It gives an effective and simple cleaning action for contaminated materials and surfaces.

Patent DE-4314820-A1 (DE)
Title: Water turbine (hydraulic turbine, water wheel) driven by low pressure
Inventor: LAUERMANN GERHARD
IPC: F03D5/00
Filed: 1993-04-30
Abstract: Up to now, relatively large heads (levels, heights) have been used in order to send water over a water wheel or in order to drive a turbine. My solution can be used in any desired river (stream), in order to generate the water vortex (eddy). A minimum degree of damming is required in the case of very sluggishly flowing waters (bodies of water), because there is no need for large differences in water head.   This water vortex can be used to obtain energy in small systems having an insertable rotor and electric generator. However, it is advisable in the case of larger systems to use self-floating rotors which have a shaft in the middle. A pick-up arm (tapper arm) or bridge is swivelled over the latter and connected to the shaft. In my opinion, this is a good step towards living in harmony with nature. Again, it could also create urgently required jobs. Moreover, a large number of small systems replace an atomic power station.

They can be temp. protected FETs connected in series so that their source or drain electrodes have a common junction. ADVANTAGE - Reliably transfers input voltage to its output ports and reliably prevents voltage at output ports from reaching input ports.
