Abstract: Abstract of the Disclosure A method and apparatus for reducing the bit error probability of data transmitted over a Rayleigh fading channel are disclosed.         A relatively high bit rate serial stream of data is divided into N parallel relatively low bit rate streams of data.  A controlled amount of intersymbol interference is introduced in the parallel streams.  The N parallel streams are then transmitted simultaneously over the Rayleigh fading channel.  Each bit in the N parallel stream of data has a duration longer than the duration of the typical Rayleigh fade.  Thus there is a reduced probability that a Rayleigh fade will cause a bit error.

Abstract: ABSTRACT: Integrated circuit.         Charge-coupled devices are very sensitive to clock cross-talk due to the overlap between successive electrodes. The influence of this cross-talk is reduced when the clock lines are periodically connected to earth via a low-ohmic impedance. For this purpose, each clock line is controlled from a buffer (15, Fig. 4), whose output (O) is connected to a clock line. A clamping transistor (T20) is connected between the output (O) and the earthing point (Vss). When this clamping transistor is controlled by means of the output signal (O)  (via the inverter T21, T22) and at the same time by the input signal of the buffer (15) (via the series - combination of the inverters T23, T24 and T25, T22), the output (O) is clamped at Vss at the instant at which the cross-talk is expected by means of only a single clamping transistor.

Abstract: Abstract:    A pulser circuit comprises a transistor with its drain and source arranged in parallel with a first resistor, and two SCR's each arranged in parallel with a further resistor.  These elements are arranged as a series circuit across a capacitor, and a supply terminal is connected to the capacitor for charging the same.  The gate of the transistor can be triggered to short circuit the first resistor and hence increase the forward voltage across each SCR.  This increased voltage causes breakover of the SCR's and hence discharge of the capacitor through the series circuit of the SCR's and the transistor in avalanche mode, until the voltage drops sufficiently to permit recovery of the SCR's and recharging of the capacitor in readiness for further triggering.  The result is a pulse at a circuit point between the capacitor and the series connection. This pulse has the desirable attributes of a relatively high voltage and short duration.  Moreover the recovery time of the circuit permits a high repetition rate.  Pulses of this type are useful for energising transducers of ultrasonic testing equipment.

Abstract: ABSTRACT           The method  of production  of a double knit fabric for sports garment,   namely sweater and hockey includes repeating a pattern of predetermined courses containing wales of consecutive selected groups of tuck and welt stitches to form holes in and throughout the knitted fabric.   The pattern is repeated to provide a fabric with a considerable number of holes aligned in a predetermined  geometrical  arrangement.     The  method making holes resides in knitting one to two adjacent wales on the cylinder by a  combination of many tuck stitches in consecutive courses with   welt and knit stitches associated thereto in   the courses preceding and following same tuck stitches.    The fabric can be knitted in uniform color but may also be knitted to provide horizontal  color bands  of various widths and colors depending on the yarn color and the number of consecutive courses with a different color of yarn and the desired color arrangements.   The method is carried out on a circular knitting machine including multiple knitting stations,  a cylinder with cylinder needles and tuck and welt stitches made by the cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE          A pressurized water nuclear reactor comprises a normally vertical main vessel externally duplicated by a confinement enclosure.  The main vessel contains a simplified primary circuit essentially incorporating the reactor core and an annular steam generator arranged in such a way that the circulation of water, pressurized once and for all during the sealing of the vessel, takes place by natural convection. All the auxiliary circuits conventionally ensuring cooling on shut down of such a reactor are eliminated, said cooling being ensured by a special arrangement of the space formed between the vessel and the enclosure and by the fact that the latter is immersed in an external cooling liquid, no matter what the slope of the reactor.  The shut down of fission reaction in the core is ensured by systems of absorbing elements and by the automatic displacement of part of the reflector in the case of a slope of the reactor.

Abstract: Process for the purification of waste water (effluent) with a high content of ammonium ions and containing phosphate ions by precipitation of magnesium ammonium phosphate. In a standardisation stage, the ammonium ion content of the waste water is determined and, depending on the magnitude of the ammonium ion content of the waste water, phosphate ions are added if necessary. A slurry of magnesium oxide and/or magnesium ions in excess is added in a mixing stage and the pH is adjusted to the alkaline region. Between the standardisation stage and the mixing stage a pre-treatment of the standardised water is carried out for a residence time of 5 to 30 minutes, during which the ph is adjusted to the acid region. Subsequently, in the mixing stage, the pH is slowly raised to an almost neutral level until an initial turbidity develops. Magnesium ammonium phosphate precipitates out when the pH is increased further. Discharge water materially free from ammonium ions is drawn off.

Abstract: A diode circuit for monolithic integrated circuits which has a negligible leakage current to the substrate, is designed in such a way that the usual diffusion processes for manufacturing integrated circuits can be used. The cathodes 18, 23 of the diode are designed in the epitaxial n-collector layer 15 of the circuit, while the anode consists of a p+ embedded layer 13, which is situated under this collector layer and which is manufactured at the same time as the lower part of the insulation diffusions 14. The cathode area 23 is bordered by a ring 17 of the same conductive type as the embedded layer 13 and makes contact with this. Under the embedded layer 13 there is a subcollector layer 12 of n+ type which has a contact diffusion 19 of the same conductive type. The anode layer 13 and the subcollector layer 12 have thus a low-ohm interconnection. <IMAGE>
