Patent EP-0240979-A2 (EP)
Title: Double-walled special refuse dump receptacle
Inventor: ROHRINGER ERNST
IPC: B09B1/00
Filed: 1987-04-06
Abstract: The dump receptacle has an outer wall (1) and an inner wall (3), the inner wall (3) consisting of several, adjacent wall elements which are supported on the outer wall (1). When repairing the inner lining of the dump receptacle, individual wall elements can be removed through the space between the inner wall (3) and the outer wall (1). This dump receptacle permits the repair of the lining even if the receptacle is full and is thus especially suitable for the long-­term storage of special refuse.

Abstract: Apparatus and method are provided for investigating surface structures irrespective of the materials involved. A fine scanning tip (26) is heated to a steady state temperature at a location remote from the structure (22) to be investigated. Thereupon, the scanning tip (26) is moved to a position proximate to, but spaced from the structure (22). At the proximate position, the temperature variation from the steady state temperature is detected. The scanning tip (26) is scanned across the surface structure (22) with the aforesaid temperature variation maintained constant. The scanning tip (26) is moved both perpendicularly of, and parallel to, the surface structure (22) by means of piezo electric drivers (28, 30, 32). Feedback control (36) assures the proper transverse positioning of the scanning tip (26) and voltages thereby generated replicate the surface structure (22) to be investigated.

Abstract: According to the invention, the ducted propeller in accordance with PCT.EP 8,500,057 is improved in output and quietness by means of four measures. The shroud acts only as a narrow strip at the point of maximum and minimum steepness on consecutive delivery blades. It is applied on the delivery blade at the site where flow separation occurs in the case of a free delivery blade. Transition from shroud to delivery blade with a large radius of curvature. The side edges are also shaped as appropriate for the flow. As a result, the ducted propeller can be used as a general axial propeller and, in reverse operation, also as a fluid-flow engine or turbine. <IMAGE>

Abstract: The invention relates to a cable support raceway, particularly of plastic, for housing cables of different potential. For cost reasons, and also to reduce transportation space, this raceway has no rear wall. Wall brackets are used instead which latch or are inserted in side walls bridging the wall brackets on both sides. On the front side, the side walls are held together by closing brackets and are finally covered by a closing cover.

Abstract: Niobium (V) and tantalum (V) halides are converted to Nb₂O₅ and Ta₂O₅ that are free of detectable levels of halide in a two step process. In the first step, the metal halide is reacted with an alcohol and with a replacement species, such as ammonia, which reacts with the halide. This produces a metal alkoxide which is soluble and a halide salt of the replacement species which is insoluble in the alcohol and precipitates. After physically separating the alkoxide in alcohol solution from the precipitate, in a second step, the metal alkoxide is hydrolyzed with purified water to produce the oxide.

Abstract: Apparatus for and a method of decoding a video colour signal provides a digital wide band luminance signal. An analog signal Yl representing the low band luminance component of a coded video colour input signal Icv, is obtained at a first analog filter 1. An analog signal Yhc representing high band luminance and chrominance components is obtained at second means (5) which subtracts the first analog signal Y1 from a delayed input signal Icv. Signal Yhc is synchronously demodulated to provide (B-Y) and (R-Y) chrominance component signals U₁, V₁, which are digitised. Via digital delay means, single line delayed signals Ydl, U₀, V₀ and double line delayed signals U-₁, V-₁ are obtained. High band luminance signals Yu, Yv are then obtained as a function of at least two of the respective chrominance component signals U₁, U₀ and U-₁; and V₁, V₀ and V-₁. These signals Yu, Yv are remodulated and combined to provide a digital high band luminance component signal Yh. Finally, by digitally summing the digital signals Ydl and Yh a digital wide band luminance output signal Yd is obtained. Two different functions for obtaining the high band luminance components are exemplified. Wideband chrominance signals are also provided.

Abstract: A fluid flow regulator 10 comprises a body 11 defining three converging flow passages A, B and C between inlets 14, 13 and 12 respectively, and outlet 15, which is connectable to a suction source. Passages A and B each includes a valve. Turbine 16 in passage C drives actuating means periodically to operate the valves thereby to cause passages A and B periodically to be opened and closed in tandem. The regulator may be employed to suck predetermined quantities of fluid from two sources connected to inlets 14 and 13, respectively. Another embodiment serves as displacement apparatus for a submersible cleaner. With passage B open to admit water to drive propeller 34 for displacing the apparatus and cleaner, passage A is closed to reduce suction at the cleaner. With passage B closed, passage A is open to transmit suction to the cleaner for it to be propelled by its own driving mechanism.

Abstract: The device has a pivotable engaging lever, by means of which a ratchet wheel is released or blocked. The pivotable engaging lever is actuated by a switching magnet. In order to be able to design the switching magnet in a way saving space and requiring little energy, it is proposed to connect the engaging lever to a magnet armature, which bears on one side against the magnet core of the switching magnet. This produces a relatively small air gap between the magnet armature and the switching magnet, so that a switching magnet of relatively low electric power can be used for actuating the magnet armature. <IMAGE>

Abstract: Electrically-programmable low-impedance anti-fuses are disclosed having capacitor-like structure with very low leakage before programming and a low resistance after programming. The electrically-programmable low-impedance anti-­fuses (13, 15) of the present invention include a first conductive electrode (12a, 12b) which may be formed as a diffusion region in a semiconductor substrate (10) or may be formed from a semiconductor material, such as polysilicon, located above and insulated from the substrate. A dielectric layer (14), which, in a preferred embodiment includes a first layer of silicon dioxide (16), a second layer of silicon nitride (18) and a third layer of silicon dioxide (20), is disposed over the first electrode. A second electrode (22a, 22b) is formed over the dielectric layer from a semiconductor material such as polysilicon, or a metal having a barrier metal underneath. At least one of the two electrodes of each anti-fuse is highly-doped or implanted with arsenic such that high concentrations of arsenic exist at the interface between the electrode and the dielectric layer. This arsenic will combine with other material and flow into the anti-fuse filament after programmed to form a low resistance controllable anti-fuse link. Circuitry is provided which allows the anti-fuse of the present invention to be programmed by application of a suitable programming voltage to input-output pins of the integrated circuit containing the anti-­fuse. Where more than one anti-fuse is to be programmed using the programming voltage applied at the input-output terminals, other additional input-output terminals may serve as address inputs to specify the anti-fuse to be programmed. 
     In another embodiment of the present invention a programmable read-only memory array comprised of memory cells including a anti-fuse in combination with a single transistor. X-address and Y-address decoder circuits are provided to both program and read the contents of any selected memory cell in the array.
