Patent EP-0019071-A1 (EP)
Inventor: LANDES KLAUS PROF DR
Filed: 1980-04-02
Abstract: The invention relates to an earth collector for heat pumps, which is characterised by the use of at least one plate-shaped heat exchanger element (12) which is driven approximately vertically into the earth and on which, for supply and removal of a heat-exchanging medium, at least one pipe (10) or the like is arranged, which extends essentially over the entire length of the heat exchanger element (12). Advantageously, a number of heat exchanger elements of this design are arranged at a distance from one another in the earth and in fluid connection with one another, so that a heat-exchanging medium circuit is created between the heat pump and the heat exchanger elements (12). The use of the heat exchanger elements described makes possible the production of an earth collector in a constructionally very easy manner as well as with a high degree of efficiency, it being possible in particular to make use simply of great depths. For optimum "operation" of the heat storage device "earth", there is introduced into the heat exchanger elements (12) on cold days a heat exchanging medium with a lower temperature in relation to the temperature of the earth, and on warmer days a heat exchanging medium of higher temperature, the heating of the heat exchanging medium taking place by means of excess heat (sun, air). <IMAGE>

Abstract: In a multipoint data communication system a master modem and a plurality of tributary modems are interconnected via respective transmission channels. Adaptive equalizer circuitry (55,56) in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from the tributary by an appropriate ensemble of tap coefficients stored in a memory (91). Timing-acquisition circuitry (29) adjusts the phase of the master's sampling circuitry (23, 27) at the start of transmission from a given tributary so that the received signals are sampled at the correct time points. In order to do this, a timing acquisition signal having spectral components only within the non-rolloff region of the equalized baseband-equivalent transfer function is transmitted by the tributary. The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisition equalizer outputs.

Abstract: Es wird die Orientierungsschicht einer Flüssigkristallanzeige aus einer zinnorganischen Verbindung des Typs RnSnX4-n (R = organischer Rest, X = reaktive Abgangsgruppe, n = 1, 2 oder 3) erzeugt. Vorzugsweise ist der organische Rest ein Alkyl und besteht die reaktive Abgangsgruppe aus Chlor. Zweckmäßigerweise wird die Schicht in einem Tauchverfahren aufgebracht, bei dem man die Verbindung in einem organischen Lösungsmittel löst, anschließend die Lösung auf die Trägerplatte bringt und dann bei leicht erhöhten Temperaturen trocknet. Die so erhaltene Orientierungsschicht ist stabil, haftet fest an ihrer Unterlage und gibt den angrenzenden Flüssigkristallmolekülen einen definierten Anstellwinkel, dessen Größe von der zinnorganischen Verbindung sowie der Flüssigkristallsubstanz abhängt und zwischen 20° und 90° liegen kann. Kleinere Kippwinkel erhält man, wenn man die Orientierungsschicht reibt. Die Schichten können durch Dotierung und anschließende Pyrolyse elektrisch leitend gemacht werden. Somit lassen sich transparente Elektroden und Orientierungsschichten auf sehr ähnliche Weise erzeugen.

Abstract: This invention is an improved method of producing a coated metal part in a process which comprises electroplating a nickel-zinc coating onto an electrically conductive- substrate from a bath containing nickel and zinc ions and removing substantially all the zinc from the coating. The improvement comprises supplying nickel and zinc ions to the bath from a plurality of nickel anodes and a plurality of zinc anodes. The total surface area of the zinc anodes, which projects toward the substrate is about twice as large as the total surface area of the nickel anodes which project toward the substrate. The bath composition is maintained at 0.75 to 1.25 molar nickel and 0.75 to 1.25 molar zinc by operating each anode at about the same current density. Electroplating is continued for a time and at a current density sufficient to deposit a 5 to 100 micron thick nickel-zinc coating onto the substrate. The coating is 60 to 70 weight percent zinc and 30 to 40 weight percent nickel.

The supporting member (10) comprises a convexly shaped plate (11) which extends throughout the combined working width of the soil working members (3) and a lowermost substantially hortizontal part of said plate (11) bears against the ground surface when the implement is in use. The supporting member (10) is angularly deflectable about an axis (a) which axis is in advance of said part of the plate (11) which makes contact with the ground relative to the travel direction (A). Holes (14) in carrier plates (12) and shaped recesses (13) in the carrier plates (12) cooperate with locking pins (15) and a rim at the front of the frame portion (1) in enabling the working depth of the soil working members (3) to be adjusted to different values and to enable the supporting member (10) to deflect turnably about the axis (a) through not more than substantially 15° if a stone or other hard object should become momentarily jammed between the rear of the supporting member (10) and at least one of the soil working members (3).
