Patent EP-0281738-A2 (EP)
Inventor: GOCKLER HEINZ DIPL-ING
IPC: H04L5/06
Filed: 1988-01-22
Abstract: The present invention relates to a multicarrier demodulator for separating and demodulating a digitalized frequency multiplexed signal into a plurality (L) of individual channel signals, with the separation being performed using a frequency division demultiplexer (FDM). The separated channel signals are each filtered using bandwidth limitation filters and thereafter demodulated using a synchronous demodulator. Following demodulation, the signals are filtered by interpolation filters, data (Nyquist) filters, and subsequently decided upon in a decider. The invention is characterized by the fact that the demodulator operates upon a pair of phase displaced complex channel signals.

Abstract: Ketonic compounds, in which at least one strongly electron- withdrawing substituent is bonded to the carbon atom in the neighbouring position to the ketonic group and/or in which a  pi -electron system is conjugated to the carbon-oxygen double bond of the ketonic group, have the capability to interact selectively with the anions of oxygenated acids, adducts, chelates or complexes being formed. 
<??>If the ketonic group is part of a chromophore in the corresponding ketonic compounds, a shift of the absorption in the visible or ultraviolet light region occurs on the formation of the adduct with the anions of the oxygenated acids. 
<??>The corresponding ketonic compounds can be used to detect the anions of the oxygenated acids, for example as an ion-sensitive component of an ion-sensitive part or as colour indicators.

Abstract: This invention relates to adhesives, and more particularly, epoxy adhesives. 
     The automotive industry has used sheet molding compound (SMC) for manufacture of parts for automobile bodies. Sheet molding compound typically comprises specialty thermosetting polyester resins, reinforcing fibers, thickeners to increase the viscosity of the resin and to facilitate handling, catalysts to cure the resins, filler to lower cost, improve the surface, or add specific properties, mold release agent, and pigment. 
     Thermoplastic copolymers have been incorporated in sheet molding compound in an effort to improve the appearance of painted SMC automobile components. The use of thermoplastic copolymers in SMC formulations has resulted in severe bonding problems for conventional repair adhesives. At present, there are no after market adhesives suitable for repairing parts made of SMC. 
     This invention provides a composition comprising an epoxy resin, an adduct of a tetra-substituted titanate and a di-substituted hydrogen phospite, a neutral ester of a phosphorous acid, and a curing agent for the epoxy resin. 
     The composition is particularly useful as an adhesive for bonding structures made of sheet molding compound to like structures, to steel, and to other substrates commonly used in the automotive area.

Abstract: A system for displaying three-dimensional surface structures according to computer graphics methods extracts a surface definition from a tomographic array of data using interpolation of the data for smooth, high resolution images. Interpolation can be performed to a degree where artifact-free images are produced for all viewing orientations. Data-processing capacity and time requirements can be reduced with less interpolation while image quality is maintained for all viewing orientations by inspecting the viewing orientation and appropriately scaling the image.

Abstract: A valve gated injection molding system having a novel valve member for large volume applications. The elongated valve member (66) has a ribbed insulative portion (94) between the main steel portion (96) and a conductive portion (98) adjacent the tip end (80). The conductive portion (98) provides more rapid cooling when the tip end (80) is seated in the gate in the closed position. The adjacent insulative portion (94) provides a thermal barrier to reduce heat flow along the valve member to the conductive portion (98). This combination avoids sticking of the tip end (80) when the mold opens and thus allows cycle time to be reduced. The conductive portion (98) has an integral beryllium copper plug (108) which is supported by radially extending ribs (102) of the insulative portion (94) to withstand continual repeated impact loading every time the gate is closed.

Abstract: A filter circuit (2) is automatically tuned so that the positions of the poles and zeros of its frequency response characteristic are maintained in substantially fixed ratios to an input frequency (f r ). To this end the arrangement comprises a frequency discriminator (1) having its output 5 coupled to a controllable element (8) of a resonant circuit included therein, so that the resonant frequency of the resonant circuit is maintained equal to the input frequency. The output 5 also controls a counterpart (13) to element 8, which counterpart is included in an auxiliary circuit (3). The filter circuit is tuned by controlling an element (10) included therein, which element also has a counterpart (14) included in the auxiliary circuit, both these last elements being controlled by the auxiliary circuit output signal. The auxiliary circuit output signal is determined by the ratio between parameters of the respective counterpart elements (13,14) which correspond to parameters of the tuning elements (8,10) which govern the tuning frequencies, and acts to maintain this ratio, and hence the aforementioned ratios, substantially constant.
