Patent EP-0203253-A2 (EP)
Inventor: HENGELHAUPT FRITZ DR
IPC: H01R4/70
Filed: 1986-01-21
Abstract: The invention relates to an encapsulated non-disconnectable electrical conductive connection in the field of electrical installation, telecommunications technology and electrical equipment and installation construction, using a connecting sleeve of dielectric material, and a process for its manufacture. The object of the invention is a corrosion-proof connection of electrical conductors, irrespective of the conductor material. A completely insulated encapsulation of the conductor connection is achieved with the invention. The contact resistance of the connection is low, its manufacture is simple and requires little time. The insulated conductors to be connected are fixed in a holder in a connecting sleeve of plastic, which is wholly or partially filled with a means of improving the contact. By rotating the connecting sleeve and fixing the conductor to the sleeve input the items are twisted, the means of improving the contact resulting in a reduction in the contact resistance. In the completed connection, the insulating sleeve exerts a contact pressure on the twisting, and the metallic conductors are encapsulated with respect to the external air.

Abstract: A preheater for liquids, particularly fuel, includes a bowl-shaped housing provided with a bowl cover to form a closed chamber. A superficial heating chamber extends along the side wall of the housing to form at least a portion of a flow path for liquid to be preheated extending from an inlet on the cover through the heating chamber and the interior of the housing to an outlet on the cover. An electric heating foil directly contacts the exterior of the superficial heating chamber for heating the liquid flowing through the flow path and has its outer surface covered by a reflective foil and thermal insulation. A filter may be accommodated in the bowl-shaped housing to filter the liquid flowing through the flow path. Helical guide ribs in the superficial heating chamber significantly lengthen the flow path.

Abstract: An interconnection pattern made of aluminum alloy, such as Al-Cu, on a semiconductor IC is dry etched in an etching gas. When an etching gas containing chlorine is used, residual chlorine on the substrate is difficult to remove, and causes corrosion of the patterned aluminum alloy layer. According to the present invention, the photo resist stripping process following the etching process is carried out by a downstream stripping process using a conventional etching gas, such as CF₄ + O₂, at room temperature, and, before the resist-stripped substrate is exposed to the atmosphere, the substrate is heated in a vacuum at higher than 100°C, thus the residual chlorine component is removed. The heating process can be carried out concurrently during the resist stripping process. By this means corrosion of the aluminum alloy interconnection is prevented.

Abstract: The biological treatment is carried out in several stages to break down the organic carbon compounds and oxidise the nitrogen compounds.   The organic carbon compounds are broken down in a first stage, then an intermediate clarification is carried out, and a filtration is provided upstream of the nitrogen-oxidising stage which is designed as disc aerator. The intermediate clarification can be dispensed with in certain cases. The essential advantage is that considerably higher nitrification efficiencies are achieved compared with known processes, and thus smaller, but more efficient, disc aerator systems can be used. <IMAGE>

Abstract: This disclosure relates to an electro-acoustic transducer with a diaphragm (12) consisting of a corrugated sheet (34A) and a thin flat shet (32). The corrugated sheet has a plurality of conductors (36, 39) in rearwardly extending projections (P) and sheet (32) is secured to the front, flat surface (29) of the corrugated sheet (34A). With conventional diaphragms, the corrugations on the sheet are not secured to each other thereby resulting in a flimsy structure with an uneven front surface which prevents sound waves emanating from the surface from being in phase. The front sheet of the diaphragm (12) rigidifies it such that the corrugated sheet (34A) remains even and the projections (P) remain in alignment with the pole pieces (44, 46) of the magnet assembly (14). To obtain good frequency response and the desired impedance, more conductors are necessary than those used in the conventional diaphragms. The conductors (36, 39) in the present invention are deposited on a blank (34) directly opposite each other such that the blank can be readily folded without bowing or being otherwise deformed. Also, as the diaphragm (12) is oscillated, air is forced around the conductors (36, 39) and vented through the gaps in the magnet assembly (14) thereby relieving heat buildup.

Abstract: A digital timing signal generator and voltage regulator circuit is provided. In one embodiment the circuit includes a delay line. The delay line opera­ting voltage is derived from digitally encoded power/­timing signals transmitted by an isolated logic control circuit. The delay line receives and propagates the digitally encoded signals. Outputs of selected stages of the delay line are tapped to provide multiphasic timing signals for use by associated logic circuits. A plurality of gates having inputs connected to various stages of the delay line receive selected timing signals as they propagate along the delay line. Increases in the operating voltage cause the selected timing signals to sequentially activate the gates. The output of each activated gate then goes high and current flows through an associated load resistor connected between the output of the gate and ground to continuously load the supply voltage and thereby regulate it. In variations of this embodiment, two and three levels of gates and load resistors are provided to progressively load the supply voltage and thereby provide additional regulation thereof. In another embodiment, a ring-oscillator comprised of CMOS inverters generates the timing signals. The ring oscillator consumes current in approximately a square relationship with increases in its supply voltage and thereby regulates the voltage.

Abstract: A hardware cartridge (20) performs the function of a verifiable, use-once authorization. The hardware cartridge is provided with physical security so that its contents are not accessible except via a specific protocol. The cartridge stores data in two or more segments (120,220). The cartridge responds to a query or challenge by outputting that portion of the data it stores selected by the query or challenge. Assuming the authorizing device has access to the complete contents of the hardware cartridge, it can verify the authenticity by receiving only that portion of the contents selected by its query. In one embodiment, the two segments comprise a pair of shift registers which feed data to a multiplexer (22); the multiplexer is controlled by the query to output the selected portion of the stored data. In another embodiment, a plurality of segments are stored in a random access memory which is addressed by the query. In both embodiments, after the selected data is output, the hardware cartridge no longer stores at least the unselected portion of the originally stored data.

Abstract: Sampled servo data comprising one pit centered on a track and two pits spaced l/4 track pitch from track center on opposite sides thereof provide for two sinusoi­dal tracking signals, one radially phase offset from the other by 90 degrees. A first tracking signal derived from subtracting the signals of the offset pits has a zero crossing at track center and is used by the servo system for tracking. Its derivative is used for damping. A se­cond tracking signal derived from all three pits has maxima at track centers and is therefore 90 degrees out of phase with the first tracking signal. This second signal provides track crossing information, and when used in qua­drature with the first tracking signal, provides infor­mation about the radial direction of crossing. The second signal also provides a control signal for inverting the damping signal while between tracks when the derivative of the first tracking signal would ordinarily be negative and provide for negative damping.
