摘要:
A contention-based datalink couples a receiving station and a plurality of sending stations. A first sending station has established a communication session with the receiving station. If a second one of the plurality of sending stations requests a call setup for a higher priority low-latency transmission, the receiving station sends a poll to the second sending station. The poll causes the first sending station to temporarily suspend its transmission activities and permits the second sending station to transmit a real time protocol (RTP) datagram. Upon completion of transmission from the second sending station, the suspended transmission from the first sending station resumes in a transparent fashion. The receiving station controls transmission rate by sending poll requests at intervals determined by a data value transmitted from sending station. Within the sending station, datagrams in an output queue are monitored and polling rate varied so as to maintain the number of datagrams in the output queue at an optimal level.

The invention relates to an actuating device (1), especially for use in a throttle device (2), comprising a turning spindle (4) rotatably mounted in the device housing (3). Said turning spindle is functionally linked via a transmission device (7) with a drive device (5) to displace an actuating element (6) that is liked with the turning spindle. The aim of the invention is to provide an improved actuating device that is secure and has a simple design and that can be telecontrolled in a simple manner without major maintenance work, without losses of functionality of the actuating device and at reduced costs. To this end, the actuating device (5) comprises at least two separately or synchronously operated motors (8, 9) and the transmission device (7) has at least one self-locking transmission unit (10), said transmission unit (10) being functionally linked with the two motors (8, 9) for turning the turning spindle (4).

Die Erfindung bezieht sich auf eine Leuchte mit einem Gehäuse (10), das einen Profilrahmen und ein- oder zweiseitige Lichtaustrittsflächen aufweist. Der Rahmen setzt sich aus ersten und zweiten Rahmenteilen (2.1,2.2) zusammen, die mit Hilfe von Zugfedern (4) zusammengehalten werden. Es sind in den Eckbereichen des Gehäuses (10) Eckverbindungseinrichtungen (3) angeordnet. Zu den Eckverbindungseinrichtungen (3) gehört ein erster Verbindungsteil (6), der mit einem ersten Rahmenteil (2.1) verbunden ist, und ein zweiter Verbindungsteil (5), der mit dem zweiten Rahmenteil (2.2) verbunden ist. Die beiden Verbindungsteile (5,6) lagern im geöffneten Zustand des Gehäuses (10) in einer ersten Lagerstelle (7.1) und im geschlossenem Zustand in einer zweiten Lagerstelle (7.2) ineinander.
摘要:
A programmable control for load management of a plurality of electrical power loads (F) is disclosed which contains at least two groups (F1, F2) of load controllers for controlling the power supply to loads connected to various preselected load controllers. A group selector (10) selects which of the groups is functionally operative at any given instant in time based on environment or other criteria. A serial selector (20) commonly connected to each of the load controllers in the groups serially selects one of the load controllers in each group for conduction for at least one period of the serial selector. There is provided a first set of programming points (D) situated at the input to the load controllers. The programming points are selectively connected by wires or diodes in any desired fashion to modify the conduction period or order of the various load controllers. A restart delay (30) mechanism is included, which is operative in the event of power failure, to delay the conduction on any of the load controllers for a period of time upon restoration of power.

The invention provides an isolated or purified T cell receptor (TCR) having antigenic specificity for a cancer antigen, e.g., a renal cell carcinoma antigen, wherein the TCR recognizes the cancer antigen in a major histocompatibility complex (MHC)-independent manner. Also provided are related polypeptides, proteins, nucleic acids, recombinant expression vectors, isolated host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions. The invention further provides a method of detecting the presence of cancer in a host and a method of treating or preventing cancer in a host using the inventive TCRs or related materials.

A pressure sensor has a multiplicity of piezoelectric converter elements which are arranged such that they are essentially parallel to a force-recording or pressure-recording direction. Said converter elements may be in the form of fibres, small bars, plates or the like and may also be in the form of a thick or thin layer. When the converter elements are in the form of fibres, small bars or plates, they are arranged at a distance from one another by means of an insulating material and/or are at least partially embedded in said material. In order to improve such a pressure sensor to the effect that it can also be used for high pressures, for a long service life and for different mechanical applications, a support material having greater mechanical rigidity than the converter elements, in particular in the force-recording or pressure-recording direction, is assigned to at least a number of piezoelectric converter elements or the piezoelectric converter element is applied, in the form of a layer, to a supporting body made from this support material and is electrically contact-connected, for example, by means of a bottom electrode, which is arranged between the converter element layer and the supporting body, and a cover electrode which is applied to an outer side of the converter element layer.

The invention relates to a rotating regulating device (1), especially for a valve comprising a pivotable or rotatable valve body. Said device comprises at least one actuating device (2) for rotating a regulating element (3) which can be connected to the valve body in a moveable manner. The aim of the invention is to improve one such rotating regulating device in such a way that it is precise and reproducible, and can be especially automatically actuated. In order to achieve this, the regulating element (3) is a rotating collar (4) which is rotationally positioned in relation to a bearing collar (5), and the actuating device (2) comprises at least one mechanism (6) which converts a linear movement into a rotational movement.

The invention relates to a method and a device for the purification of wastewaters, particularly for anaerobic purification, in a receptacle (19) receiving a medium under gas generation, whereby the generating gas is collected in a gas collector (3), the constituents of the medium carried off by the gas are separated and the separated constituents are fed back to the medium downstream from the gas separator. In order to achieve improved purification in a simple constructional manner, the medium is suctioned from the upper area of the receptacle by means of a lifting effect of the ascending gas and fed back into the receptacle.

A centering and self adjusting chuck (1) for clamping stock includes at least three circumferentially spaced dependent jaws (28) that initially are displaced by being simultaneously radially inwardly driven equal distances under low pressure to center the stock positioned there-between and further includes at least three other circumferentially spaced independent jaws (73) that are then independently displaced by being radially inwardly driven under low pressure any distance required to have each such independent jaw (73) engage the centered stock, the dependent and independent jaws (28, 73) finally being displaced by being simultaneously radially inwardly driven under higher pressure tightly and uniformly to clamp the stock therebetween for subsequent machining.
