Filed: 1990-03-14
Abstract: A power supply abnormality detection system of the present invention includes a low-frequency power amplifier circuit (12) equipped with a built-in overvoltage protection circuit for detecting a voltage exceeding, for example, a reference power supply voltage. In accordance with the presence or absence of an overvoltage detected by the overvoltage protection circuit, a detection signal emerges from a detection output terminal (14) provided outside the low-frequency power amplifier circuit (12). In accordance with that emerging detection signal, a counting circuit (20) counts an overvoltage detection amount as pulses and, when the number of pulses exceeds a predetermined reference number, a power supply line relay section (18) is operated so as to interrupt the supply of that overvoltage and an abnormality alarm device (16) informs the generation of the overvoltage to an outside.

Abstract: A process for haemodialysis, includes providing a dialyzer utilizing an electromagnetically controllable double membrane pump, whereby the membranes are each supported against an incompressible liquid during the stroke movement of a pump piston. The process includes filling the space between the membranes with the incompressible liquid, stroking the piston thereby sucking deaerated fresh dialysate through an opening in a front cover plate and into a first swept space bounded by one membrane and the front cover plate while simultaneously discharging used dialysate through an opening in a second cover plate and out of a second swept space bounded by the other membrane and the second cover plate. The pump piston then strokes to the other end of its range thereby discharging the fresh dialysate through another opening of the front end cover plate, and sucking used dialysate through another opening of the second cover plate.

Abstract: A photometric method and device for the analysis of biological samples treated with fluorescent reagents are proposed. 
     The method provides for the excitation of the sample contained in a test tube (10) by one or more radiations of predetermined wavelengths, and the measurement of the radiations emitted by fluorescence by a count of the individual photons emitted by an appropriate fraction of the surface of emission under consideration, to avoid the effect of the edge reflection. 
     The device provides an illuminator (1,4,5,6) to excite the molecules of the fluorescent reagent, and an avalanche photodetector (16) which receives the radiation emitted through an inverted microscope, of the reflection or refraction type.

Abstract: A cordless remote telephone unit communicates with a telephone line through a stationary self-powered base unit. The base unit is not plugged into an electrical household receptacle and is therefore completely portable to any location having a telephone jack. The remote unit is portable to any location within the radio range of the base unit. The base unit does not require a household electrical receptacle because non-rechargable batteries are used in the base and remote units, so there is no need for a battery charger. Moreover, power consumption is minimized when the system is idle by cycling the battery power in both the remote and base units. As communication begins, continuous battery power is proved in place of the cycled power in the base unit in reponse to receiving from the remote unit a 5 KHz activation tone, a security code and a 22 Hz pilot tone, or in response to a ring received from the telephone line. After communication is established between the two units, the base unit derives reliable power through its hook switch directly from the telephone line using a power regulator suited for the purpose, further reducing power demand on the batteries. Power cycling in the remote unit is replaced by continuous battery power in response to receiving from the base unit a ring tone generated by the base unit ring detector, followed by a security code, or whenever the remote unit hand set is picked up by the user. In one embodiment of the invention, the remote unit handset is connected to a remote unit chassis by a cord, and the remote unit radio receiver and radio transmitter circuits use the cord as their antenna.

Abstract: An encoder encodes a plurality of bit sequences of a digital signal into data codewords having improved signal characteristics, i.e., limited maximum run lengths and limited cumulative DC-offsets. Then, the encoder performs error protection encoding on the data codewords using a forward error correction ("FEC") code to form an FEC code block from a number of the data codewords. Preferably, the FEC code block is formed by generating a number of check or FEC bits equal to the number of data codewords in the block, and then concatenating one FEC bit and its binary complement with each data codeword so that one FEC bit and its complement are interposed between each successive codeword. In a preferred embodiment, a 96-bit FEC code block is formed from eight 10-bit data oodewords (formed by an 8b/10b data encoder), eight FEC bits, and eight FEC complement bits. In another preferred embodiment, each 16-bit input sequence (DATA 0, DATA 1) is encoded into a 20-bit data codeword pair made up of a 9-bit codeword and an 11-bit codeword. An implementation of this embodiment uses a precoder and 8b/9b and 10b/11b sub-encoders, which collectively perform 16b/20b encoding. Then, an 8-bit FEC word is generated from an 80-bit block consisting of four of the 20-bit codeword pairs. One FEC bit and its binary complement are concatenated to each 9-bit and 11-bit data codeword, resulting in a 96-bit FEC block. Preferably, the data codewords in the FEC blocks are 3/4/3 codewords. Also, the complementary FEC bit pairs can be used at the receiver to obtain proper framing of the FEC code block prior to decoding.

Abstract: The invention relates to a circuit arrangement for driving a monochrome picture tube, comprising a picture signal amplifier with adjustable gain, the input signal polarity of which can be switched over for obtaining a positive or negative display, different reference potentials being provided for the amplified picture signals. The reference potential for the positive display can be changed with the gain of the picture signal amplifier (11, 12) in such a manner that a predetermined maximum input voltage excursion always generates an output voltage excursion up to the reference potential for the negative display. This dispenses with a correction of the contrast and/or the brightness after switching over from negative to positive display. <IMAGE>

Abstract: 2.1 To increase the aperture of a sector into which sound waves are emitted from a flat base, the base is electronically curved into a conic section function, for example a sector of a circle, by phase-delay networks. 2.2 To economise on power amplifiers, transmission signals are, according to the invention, subjected to phase shifts, phase values being determined according to a parabola for each transducer position, the focal point of the parabola being equal to a quarter of a maximum phase shift. The maximum phase shift is equal to half the base length, referred to the mean wavelength of the sound waves, which is multiplied by  pi  times half the aperture. The phase values for the individual transducer positions are reduced by modulo 2 pi and combined to form residual phase values if they are within a specifiable interval. The number of power amplifiers is determined by the interval. Transducers having equal residual phase values are combined and fed from the same power amplifier. 2.3 The circuit arrangement is advantageously applicable in underwater sound engineering and in medical diagnosis. <IMAGE>

Abstract: 2.1 Fluorine-containing wastes are encountered in aluminium primary production mainly as used lining material from the electrolysis cells. The service life or durability of an electrolysis cell trough lining is normally 4 to 8 years. All the used lining material then usually has to be chipped out of the electrolysis trough and disposed of. 2.2 The object is to develop a method which makes it possible to remove at least 98% of the fluorine content from fluorine-containing wastes, in particular from aluminium primary production, at temperatures markedly below 1000 DEG C. It is intended to produce a harmless final waste having a fluorine content of not more than 0.5% by weight and at the same time to make it possible to recover pure AlF3 in a simple way. The method is characterised in that, in a first stage of the method, finely divided fluorine- and carbon-containing wastes are heated to temperatures between 400 and 900 DEG C together with SiO2 or SiO2- containing materials in the presence of gaseous chlorine, in which process more than 98% of the fluoride content of the feed mixture is converted into gaseous silicon tetrafluoride, and in a second stage of the method, the gaseous SiF4 is converted, either directly or after reaction to form fluorosilicic acid, into aluminium fluoride by reacting SiF4 or H2SiF6 with aluminium hydroxides or aluminium oxides. 2.3 The method is preferably used for working up fluorine containing wastes.

Abstract: The transport method described makes possible transport of printed products, in particular printed products in the form of an overlapping flow, at constant or changeable rate over transport runs of any length, which can also contain rising or falling parts and curves in the direction of transport. The method is based on the fact that each individual printed product or small group of printed products is transported by one transport element over a step length (S), which is small when compared with the overall transport run, and is then taken over by a following transport element, while the first transport element is moved back to its starting point again. This process is repeated in a cycle with the temporal cycle length (T). The corresponding device consists of a stationary support and of a large number of transport elements which are driven in a clocked manner. A transport run can comprise a large number of transport modules, no transfer units being required between the individual modules. All modules of a transport run work in the same cycle.
