Inventor: TOL SIMON JOHANNES MARIA
IPC: H04L7/02

Abstract: A receiver of a system for transmitting data symbols at a given baud-rate comprises a symbol detector (7) operating at the baud-­rate 1/T and means (6) for optimally conditioning received data symbols for this symbol detection. From the received conditioned data signal [s(k)] a phase error signal [e(k-1).ĉ(k)] is derived that is representative of a phase difference between a locally generated baud-­rate clock signal and a baud-rate clock signal inherent to the received data symbols, and the receiver comprises means (11, 12) for the reduction of this phase difference step-by-step in response to the phase error signal [e(k - 1).ĉ(k)]. This receiver further includes an accumulator (44) for determining the mean value [u(k)] of the phase error signal over a predetermined number (M) of symbol intervals and a detector (45) for establishing whether this mean value [u(k)] is situated in a zone whose boundaries [±V r (k)/N] are determined by a given fraction (1/N, N > 1) of the level [V r (k)] of the conditioned signal [s(k)]. If the mean value [u(k)] of the phase error signal is situated in this zone, the process of shifting the phase of the local clock signal step-by-step is stopped.

Abstract: Members especially hollow members 10, 12 such as pipes and pipe fittings one member 12 of cross-linked polyethylene say and the other member 10 of medium density polyethylene say are joined by fusion using a butt fusion machine. End surfaces of the members are pressed at higher pressure against a hot plate 18 to upset only the medium density material to form beads 20, 22. No cross-linked material is upset to form beads. The pressure is reduced during a soak stage then the plate is removed and the surfaces are mutually engaged at the higher pressure. The beads formed are adjacent the interface between the members and both beads are offset towards the medium density material, member 10. Careful alignment will avoid faults caused when the beads do not cover exposed parts of end surfaces. Other materials include polypropylene, copolymer or monopolymer types. Natural gas distribution systems can be fabricated using the invention.

Abstract: nickel-cadmium alkaline secondary battery wherein the content of nickel hydroxide and/or nickel oxide in a negative electrode active material is 2 to 60 wt % based on the total amount of cadmium and the ratio of the content of cadmium hydroxide in the negative electrode to the content of nickel hydroxide in a positive electrode active material is up to 0.95 by weight; a manganese-cadmium alkaline secondary battery wherein the ratio of the content of cadmium hydroxide in a negative electrode active material to that of manganese dioxide in a positive electrode active material by weight is up to 0.84 in an electrically discharged state; and a silver oxide-cadmium alkaline secondary battery wherein the ratio of the content of cadmium hydroxide in a negative electrode active material to the content of silver in a positive electrode active material by weight is up to 1.36 in an electrically discharged state are disclosed. These batteries show such sharp and remarkable changes in voltage in the final stage of charging that the charging can be controlled with high accuracy. They scarcely require reserve cadmium hydroxide and hence an oxygen gas generated from the positive electrode can be effectively absorbed, thus realizing rapid 1C-charging and ui- trarapid 10C-charging of a rectangular battery with high reliability.

Abstract: A process and apparatus for eradicating pests in organic bulk goods, for example cereals, are provided. According to the process, the bulk goods, from which pests are to be eradicated, are introduced into a pressure-resistant vessel (10) in which compressed air is then first introduced until a minimum pressure of 4 - 6 bar has been reached. Carbon dioxide under a substantially higher pressure is then introduced until a pressure of 15 - 25 bar has been reached in the vessel interior. The pressure reached is maintained over an eradication time of a few hours, whereupon the vessel (10) is then depressurised and the bulk goods from which pests have been eradicated are discharged. As the apparatus, an upright elongate cylindrical vessel (10) with an inflow-distribution pipe (14) extending in its interior is provided, which pipe can be connected via piping (40, 42, 45, 47) fitted with valves (41, 42a, 46, 48) to a compressed-air source (32) and to a carbon dioxide gas source (30, 31). <IMAGE>

Abstract: The invention relates to a digital transmission system with two terminal stations (transceiver stations) (A, B) and a transmission path (FF) between the terminal stations (A, B), the receiving component of which contains devices for equalising signal distortions of the transmission path. To improve the transmission quality and range of the transmission system and to achieve a simple structure, the solution according to the invention provides one device (AE) in the receiving component of only one terminal station (B) to equalise the received signal, and one pre-distorter in the transmitting component (S2). The pre-distorter (VV) is activated by a signal derived from the equaliser (AE) in such a way that  the signal  transmitted  to the distant station (A) is pre-distorted according to the transmission path (FF). In mobile radio systems, the equaliser (AE) and the pre-distorter (VV) are disposed in the fixed station. <IMAGE>
