Abstract: The invention relates to special constructional forms of double belt presses which are suitable in a special manner for the melt impregnation of long glass-fibre mats with thermoplastics and for compressing a scattered heap of thermoplastics to form endless webs. These presses have the special features of, on the one hand, a wedge-shaped feed zone in which the incoming material is brought to its final thickness under pressure which is continually increased in various ways and, on the other hand, means for the lateral sealing of the reaction zone, by which means a flowing out of the material is prevented and a uniform quality of the webs over the entire width is achieved. <IMAGE>

Abstract: The biologically recognising layer on a solid phase consists of biologically recognising molecules which have molecular regions which recognise (bind) the analyte and molecular regions which do not recognise (not bind) the analyte. The biologically recognising molecules are aligned via molecular regions which do not recognise the analyte on a suitably modified surface. The biologically recognising molecules are crosslinked with this aligning surface and are covalently modified. The molecular regions recognising the analyte are not modified by the covalent bonding and retain their binding activity. This layer is produced in a two-stage process. In the first step there is adsorption of the biologically recognising molecules, of the aligning molecules and of the carrier molecules. In the second step there is covalent anchoring by crosslinking the molecules with one another. The crosslinking takes place by photolytic activation of the reagent linked to the carrier molecules. This reagent still contains groups which confer solubility in water after its reaction with the carrier molecules.

Abstract: The object of the invention is to provide a manufacturing method of a complex shaped R-Fe-B type sintered anisotropic magnet improved the moldability of injection molding and preventing the reaction between R ingredients and binder and controlled the degradation of magnetic characteristics due to residual carbon and oxygen. Utilizing the R-Fe-B type alloy powder or the resin coated said alloy powder, and methylcellulose and/or agar and water, instead of the usual thermoplastic binder, it is mixed and injection molded. The molded body is dehydrated by the freeze vacuum dry method to control the reaction between R ingredients and of the R-Fe-B alloy powder and water; furthermore, by administering the de-binder treatment in the hydrogen atmosphere, and sintering it after the dehydrogen treatment, residual oxygen and carbon in the R-Fe-B sintered body is drastically reduced, improving the moldability during the injection molding to obtain a three dimensionally complex shape sintered magnet.

Abstract: In a cellular telephone system of the type having TDMA channels, the beginnings of the time slots of an uplink transmission are offset from the beginnings of the time slots of a downlink transmission by a predetermined amount. By offsetting the beginnings of the time slots, a mobile station is able to operate at an extended distance from the base station without any modifications to the mobile station. Because the mobile stations can operate at a greater distance from the base station without a decrease in the number of available channels, the cellular telephone system is particularly suitable for use in rural areas or coastal areas.

Abstract: A device for converting binary logic pulses into an output current and the output current being switchable between a positive and negative polarity. The device provides a charge pump circuit which is suitable for the phase-detector stage in a phase-locked loop (PLL) circuit. The charge pump circuit comprises an input stage for the "UP" binary logic pulses and a second stage for the "DOWN" binary logic pulses. The input stages comprise emitted-coupled transistor pairs. The circuit includes current sources and current sinks for generating the output current in the input stages in response to the binary logic pulses. The circuit features a pair of commutating diodes between the outputs of the input stages. The commutating diodes control the output current and the leakage current in the idle state. The circuit also includes a clamping circuit to limit the voltage swing across the commutating diodes. The charge pump circuit according to the present invention exhibits a fast response time, a symmetrical response to the binary logic pulses, and virtually zero leakage current in the idle state. The charge pump circuit utilizes non-complimentary bipolar processes and is suitable for a monolithic integrated circuit implementation.

Abstract: A water treating device for a domestic water handling device such as a toilet water tank, an air conditioning drain pan or a humidifier includes a housing having permanent magnets in a flow path of water flowing through the housing via openings in the housing, to collect free ions in the water. An antimicrobial polymer disinfectant agent is in a mass inserted in a chamber in the housing and/or in a polymer in a housing surface. The housing is configured so an air bubble forms against the housing roof to assure that a base of the housing rests on the floor of the water handling device. Ribs adding structural strength to the cover are aligned and have approximately the same size and shape as slots in the cover roof through which water passes so the ribs obscure the magnets from view from above and to sides of the cover. The magnets are held in place by a spring finger extending upward from the base to exert a force downwardly against the magnet upper pole face.

The characters (112) have predetermined heights and widths and spacings therebetween. The verification device (100) comprises an oscillator electrode (128) and associated horizontal and vertical electrodes (132, 136). A time-varying oscillator signal is coupled to the oscillator electrode (128). The spacing of the horizontal and vertical electrodes (132, 136) in relation to the oscillator electrode (128) is determined by the spacing between the metallized characters (112) on the thread (116). A valid security thread (108) capacitively couples the oscillator signal into the horizontal electrode (132) but not the vertical electrode (136). On the other hand, a counterfeit security thread will couple the oscillator signal into both the horizontal and vertical electrodes (132, 136). Signal processing electronics (140) is provided to sense these valid and counterfeit threads (108).

Abstract: A method and apparatus for achieving optimum optical contrast for detecting registration marks in a multicolor print-black-first, color electrophotographic printing machine. A black mask having voids in the shape of a registration mark is formed on the photoreceptor (10). A high contrast color is then overwritten on the mask and in the voids, forming marks which indicate the position of the black image. A delay time measurement between a registration mark of a non-black color and the non-black color in the voids of the black mask will provide the relative registration between the black and non-black color imagers as those registration marks on the photoreceptor pass a marks-on-belt sensor. A second method utilizes a registration mark imaged by each imager of the color printing machine, but all of the latent image registration marks are developed with a single non-black color toner. A mark-on-belt sensor is then used to determine the relative position of the various color imagers and to send signals to the controller to make appropriate corrections.
