Title: Take-off and deflecting device for a plastic tubular film produced from a fixed film blowing die
Inventor: KARL VEIT-HOLGER DR ING
IPC: B65H23/32
Filed: 1988-09-21
Abstract: For a plastic tubular film (1), produced from a fixed film blowing die, in which the collapsing (2) and pinching-off device (4) rotates reversibly through 360@ around the feeding device of the tubular film (1), a take-off and deflecting device is proposed in which there is rigidly fastened on the pinching-off device (4), at a distance from the axis of rotation, a roller (5), the axis of which describes a plane perpendicular to the axis of rotation and which, seen in the transporting direction of the tubular film (1) is arranged downstream thereof. The nearest, and consequently first turning bar (7) in the transporting direction of the tubular film (1) is connected to the pinching-off device (4) such that it can swivel on an axis coinciding with the axis of rotation. The second turning bar (9) is fastened in a frame (10) outside the axis of rotation such that it can swivel about an axis running parallel to the axis of rotation. The frame (10) is in connection with the pinching-off device (4) such that it can swivel on the axis of rotation. The third turning bar (11) is arranged such that it can swivel in a spatially bound manner. <IMAGE>

Title: Wind power station
Inventor: SPINDLER ADOLF
IPC: F03D3/02
Filed: 1988-10-18
Abstract: Two single-axle units on a jointly rotatable substructure, the left-hand unit rotating clockwise, the right-hand unit rotating counter-clockwise, each unit, however, being independent in terms of the drive. The wind protection offers the returning blades of the two units protection from the contrary wind and leads the diverted airflow directly to the recesses of all of the blades of the two aggregates. By this means, the number of pulses is increased and begins earlier, and the air flow on both sides of the units is also concentrated. The drawings demonstrate the upper part of the plant, at the front and rear of the vertical supporting columns having the longitudinal and transverse connections. The wind protection is fastened on the front longitudinal connections but is illustrated without struts.

Title: Process for reducing nitrogen oxides in exhaust gases
Inventor: MUELLER DETHLEFS KLAUS DR
IPC: B01D53/32
Filed: 1989-01-02
Abstract: The process is based on the free-radical reduction of nitrogen oxides by free radicals which are situated in a plasma gas stream. The plasma gas stream is composed of a carrier gas which entrains small volumes of a high-temperature plasma, so-called "hot pockets". The high-temperature plasma is generated inhomogeneously in a small volume by rapid gas-dynamic rotation of a plasma breakdown and is intermittently entrained by the surrounding carrier gas, achieving a long life of the free radicals contained therein. The plasma gas stream enters the exhaust gas stream at over 100 m/s and, via mixture with this, leads to an efficient reduction of the nitrogen oxides. In addition, ammonia can be added to the exhaust gas stream. This gives a further increase of the overall efficiency of the nitrogen oxide reduction by the production of catalytically active free radicals.

Title: Closures for containers
Inventor: CRITCHLEY RICHARD JEROME
IPC: B65B7/28
Filed: 1989-02-14
Abstract: The invention relates to a container closure which, in a first state, engages behind an opening in the container to be closed in such a way that it cannot readily be removed from the container. By deformation, the container closure can be brought into a second state in which it can be removed from the associated opening. The deformation and the removal take place by means of a device mounted on the door of a delivery container. In this case, the aforementioned container is brought into engagement in a sealing manner with the delivery container, the container closure and the door are connected to one another, the container closure is deformed, and the container closure and the door are lifted off together into the delivery container so that transfer of material can now take place from the delivery container into the other container. When the latter is full, the operations described above take place in reverse order and the container which has been closed again can be removed.

Title: Chip inductor
Inventor: SAKAMOTO YUKIO
IPC: H01F17/04
Filed: 1989-03-17
Abstract: A chip inductor, which is provided with a metal sheet of magnetic material which forms an inner electrode on one surface, which inner electrode interacts with the inductance component. In addition, metal sheets made of magnetic material are provided on both sides of the metal sheet which is made of magnetic material and has the inner electrode which is formed in a curved shape, in order to form a layer element. Outer electrodes are provided on both sides of the surfaces of the layer element, in order to be connected to the inner electrode. The inner electrode, which is formed in a curve, can ensure (secure) its length sufficiently to raise the inductance and, since the metal sheets made of magnetic material are also coated on both surfaces of that metal sheet which is made of magnetic material and has the inner electrode, the insulating effect and the mechanical strength are improved, so that, when a large number of metal sheets made of magnetic material, which form the inner electrode on them, are coated, their current capacity rises. <IMAGE>

Title: Combustible waste utilisation method - involves gasifying lumps by using medium flowing in same direction before flame reaction chamber
Inventor: SCHINGNITZ MANFRED
IPC: C10J3/08
Filed: 1991-03-20
Abstract: The method simultanoeusly utilises combustible waste in lump- and free-flowing-form by combining gasification in a shaft (5) with moving bed of the lumps with an autothermal flame-reaction stage in which the free-flowing material reacts with a combustion or gasification agent containing oxygen so as to form a common slag bath (3). Gasification in the shaft is effected by a medium flowing in the same direction as the lumps, the gas so formed and the remaining solids passing into a reaction chamber (2) of the flame-reaction stage. Here the gases formed in this stage react with those from the shaft and the residue to form raw gas with a high CO- and H2-content, the slag bath forming in the chamber bottom. The hot raw gas and the molten slag flow via a drain (7) into a zone (8) below, where both are cooled directly or indirectly and the slag is granulated. ADVANTAGE - Provides usable or easily-dumped solid residue, with no toxic pollution of the environment.
Patent DE-4109480-A1 (DE)
Inventor: MICHEL DIETER DIPL ING
IPC: G01D5/38
Filed: 1991-03-22
Abstract: In a photoelectric position measuring device according to Figure 4, reference marks which define in an absolute fashion the relative position of the scale and scanning plate are coded. Different diffraction images are produced with the aid of coding marks which are assigned to the reference marks and consist of differently diffracting fields (C1 to Cn). These diffraction images are detected by appropriately placed photoelements (D1, Dn), converted and output as a binary code. The binary code specifies the absolute position in coded form. The number of the fields in the coding mark determines the number of the decodable reference marks. That is to say at least 2<n> reference marks can be coded using n code mark fields. <IMAGE>
