摘要:
In accordance with a first aspect of the invention, a plasma reactor having a chamber for containing a plasma and a passageway communicating with the chamber is enhanced with a first removable plasma confinement magnet module placed adjacent the passageway including a first module housing and a first plasma confinement magnet inside the housing. It may further include a second removable plasma confinement magnet module placed adjacent the passageway including a second module housing, and a second plasma confinement magnet. Preferably, the first and second modules are located on opposite sides of the passageway. Moreover, the first and second plasma confinement magnets have magnetic orientations which tend to oppose plasma transport or leakage through the passageway. Preferably, the module housing includes a relatively non-magnetic thermal conductor such as aluminum and is in thermal contact with said chamber body. Cooling apparatus can be thermally coupled to the chamber body, whereby to maintain the first plasma confinement magnet below its Curie temperature. If the reactor includes a pumping annulus adjacent of a periphery of the chamber, then the passageway can be one which communicates between the chamber and the pumping annulus. Also, the passageway can be a wafer slit valve or a gas feed inlet. Such a gas feed inlet can be a center gas feed through a ceiling of the chamber. The module housing can rest upon the chamber side wall and the chamber ceiling can rest upon the module housing.

A video telephone (TEL) for use in an interactive video service is disclosed to establish a switched connection to a video server (VOD) to receive video signals corresponding to selections chosen by a user. In a further aspect, the video telephone (TEL) includes a card slot and chip card reader to activate the TEL by reading the VOD call number from the card data. The TEL automatically dials the VOD to establish the switched connection via the digital radio network GSM and/or the integrated services digital network ISDN.

A method to adjust the angular position of a camshaft, which is related to the arc of a crankshaft rotation, to a setpoint angular position with the help of a final controlling element that is triggered by an actuating signal from a controlling device that becomes operational when a control program is run. The final controlling element is able to be triggered in each case by one of three values of the actuating signal; the re-adjustment rate (v.sub.-- ESTIMATED) of the camshaft is estimated for its level at the beginning of the subsequent program run; from this re-adjustment rate and the known time response (c, v.sub.-- END) of the camshaft re-adjustment, after the switch is made to the actuating signal from the hold value, a special adjustment angle (.alpha..sub.-- ESTIMATED+) is estimated; and the change is already made from the early or late value of the actuating signal to its hold value when the deviation between the adjustment angle (.alpha..sub.-- ESTIMATED+) and the setpoint angular position lies within a tolerance band. The angular position of the camshaft is thereby able to be adjusted in a rapid and stable manner.

A control device for a radiator valve comprises a housing (10, 12) including an operating, display, control and power supply portion, (14, 16, 18). Said housing comprises a cut-out (24) with which it is slipped-over a motorized drive unit (30-84). When the housing (10, 12) is removed from the drive unit, a reception housing (38) for a motor (34) and a gear unit (36) can be rotated as a hand wheel with respect to a stationary drive housing (32) flanged to the radiator valve so that the valve may be manually operated. A ring (66) being rotatable with respect to the reception housing (38) and a drive housing (32) allows balancing of tolerances and matching to radiator valves of different manufacturers.
摘要:
In connection with a metal oxide electrode in an alkaline electrolyte system, especially for a brownstone electrode, the presence of cobalt as a thin film or as an alloying consitituent at the surface of the positive current drain wire, which is preferably a nickel-plated steel cup or a deep-drawing steel plate, leads to a reduction of the contact resistance between the current drain wire and the MnO.sub.2. To apply the cobalt, the current drain wire is preferably polarized in an aqueous CoSO.sub.4 solution. The cobalt film, which is formed in a thickness of less than 1 micron (depending on the Co ion concentration and the selected current conditions), imparts resistance properties to the transition between the MnO.sub.2 and the nickel-plated current drain wire even after prolonged storage, which can otherwise only be achieved with gold-plated current drain wires.
摘要:
A machine for sewing together two workpiece parts having edges of equal or unequal length by using a bead seam, especially for joining together the edge of a vamp and the shorter edge of a plug of a true moccasin shoe, so that the length of the plug matches that of the longer edge of the vamp, in only one operation. The bead seam forming device essentially consists of an auxiliary folding and ruffling finger acting in front of the needle of the sewing machine and in synchronous driving connection with the needle; several machines are described which are provided with different bead seam forming devices.
