The weft thread (24, 24a), of a respectively predetermined length, is inserted by means of an air flow in an injector (23) into the weft thread magazine (29) of a shuttle (9) traveling in a continuous movement past the injector (23). In order to be able to supply the shuttles (9) rapidly with the particular weft thread required for the fabric panel width in a multi-feed weaving loom, without thereby causing an impermissible strain on the weft thread or being required to extend the length of the weft thread magazine (29) of the shuttles (9), the injector (23) is moved conjointly with the shuttle, e.g. by a gear coupling (34-38) beginning at a start position (I) but, at a slower speed than the shuttle and over shorter distance during the insertion of the thread (24, 24a) into the weft thread magazine (29). At the end of this distance the injector is rapidly returned to the start position by a spring (42).

Adsorbent material is arranged within the adsorber and the ratio of the amount of raw gas to regenerating gas conducted over the adsorbent material adjacent the walls of the adsorber per unit area of adsorbent material is greater than the ratio of the amount of raw gas to regenerating gas conducted per unit area over the remaining adsorbent material. The amount of raw gas and regenerating gas conducted over the adsorbent material is adjusted and controlled by providing a bulkhead within the adsorber to separate the adsorbent material adjacent the adsorber wall from the remaining adsorbent material. Secondary feeding or discharge means is associated with the bulkhead area for regulating the flow of regenerating gas therethrough.

Abstract: An underspeed actuator (18) is connected to the displacement control (17) for controlling the displacement of a variable displacement pump (11) of a hydrostatic transmission (10) in response to the pressure differential between low and high pressure control signals (A, B) wherein the pressure defferential is directly proportional to the engine speed. An overspeed control valve means (41) is connected to the low and high pressure signals and decreases the pressure level of the high pressure signal received by the underspeed actuator (18) in response to the pressure differential exceeding a predetermined magnitude. This reduces the displacement of the variable displacement pump (11) thereby controlling the amount of engine overspeed caused by the hydrostatic transmission (10) driving the engine when the vehicle is descending a steep hill.

Abstract: Eine an einer Meßstelle angeordnete Sensoreinrichtung (SE) erzeugt eine Ausgangsspannung (Um), die einen nahe bei der Sensoreinrichtung (SE) angeordneten elektrooptischen Modulator (EOM) steuert. Diesem Modulator wird von einer weit entfernten Stelle (ST) aus über einen Lichtwellenleiter (LW3, LW1) eine Signallichtleistung zugeführt, der das Spannungssignal (Um) aufgeprägt wird. Die modulierte Signallichtleistung wird über einen Lichtwellenleiter (LW2) einer weit entfernten Entnahmestelle (ES) zugeführt. In dem die Signallichtleistung zuführenden Lichtwellenleiter (LW3, LW1) ist ein optisches Teilerelement (OT) angeordnet. Dieses Teilerelement (OT) zweigt nur einen geringen Teil der über den zuführenden Lichtwellenleiter (LW3) zugeführten Lichtleistung als Signallichtleistung ab. Der größte Teil dieser Lichtleistung wird über einen weiteren Lichtwellenleiter (LW4) einem Fotoelement (OEW) zugeführt, das die zugeführte optische Leistung in eine elektrische Leistung umwandelt, die für den Betrieb eines elektrischen Teils der leistungsverbrauchenden Sensoreinrichtung (SE) erforderlich ist. Diese Anordnung weist die Vorteile der optischen Signalübertragung auf und sie führt die zum Betrieb der Sensoreinrichtung (SE) erforderliche elektrische Leistung als optische Leistung zu. Sie wird vorteilhafterweise dort eingesetzt, wo hohe elektrische Potentialdifferenzen herrschen und/oder Explosionsgefahr besteht.

IPC: H04N5/06

Abstract: In magnetic video-tape equipment of the helical-scan type the vertical synchronizing information is situated at the beginning of a track near the edge of the magnetic tape. When the edge portion of the magnetic tape does not cooperate correctly with the head in the case of a faulty magnetic tape or apparatus, the vertical synchronizing information is not scanned and the resulting picture will roll in a vertical direction. However, since the beginning of a track coincides with the edges of the head-change signal, the vertical synchronizing information, in accordance with the invention, is always derived from the head-change signal, i.e. even during normal undisturbed operation, and is added to the CVBS signal, the signal scanned from the magnetic tape being blocked during this time. For this purpose the edge of the head-change signal is delayed and this delay is controlled so that normally the generation of the vertical synchronizing information from the line-pulse signals which are synchronized with the preceding track starts halfway between two such line-pulse signals or their active edges. Also when the permissible phase shift to the head change signal relative to the line-pulse signal upon each head change is taken into account the vertical synchronizing information always starts an equal number of half-line periods after the beginning of a track, thereby precluding a vertical picture jump, not even by half a line period.
