Abstract: The bulb of the lamp is closed at opposite ends by sealing parts (6), with in each case one cap (8) being fitted at one end, the cap having an electrical contact element (13) which is connected in an electrically conductive manner to a supply conductor (15) leading to a luminous means, the contact element being accommodated in a tubular extension (11) of the sealing part. The cap part (8) has an adjustment part (14; 24), which is directed inward with respect to the interior of the lamp and is in contact with the sleeve (11) via a bracket.

Abstract: An electric lamp has a discharge vessel which is sealed in a vacuum-tight manner and is made from glass, the discharge vessel being surrounded in particular by an envelope part, the discharge vessel being essentially cylindrical, and defining a longitudinal axis L, and containing two electrodes at a predetermined distance from one another as well as a filling, an electrically insulated insert part also being fitted in the discharge vessel over a central part of the axial length. The electrically insulated insert part extends at least over the distance between the electrodes EA, it is fitted in the discharge vessel without the use of a retaining device, and it surrounds the electrodes in essentially tubular fashion such that it is spaced apart from them.

Abstract: The elongate bulb (1) of the lamp, which defines a longitudinal axis (A), is closed at opposite ends by sealing parts (6; 32), with in each case one cap being fitted at one end, the cap having an electrical contact element (13; 25) which is connected in an electrically conductive manner to a supply conductor (15; 21) leading to a luminous means, the contact element being accommodated in a tubular extension (11; 22) of the sealing part; the contact element (13; 25) has an attachment part (14; 24) which is directed inward toward the lamp interior and is equipped with at least two barbs (20; 26) which are in contact with the tubular extension (11; 21).

Abstract: The lamp comprises a discharge vessel (2) which is closed off in a vacuum-tight manner and is arranged in an outer bulb (12), a getter material being held on a support body inside the outer bulb (12). The support body is a support strip (31) to which the getter material is applied, the support strip being bent in such a way that it is automatically held in the outer bulb (12) without the need for any auxiliary means.

Abstract: The process comprises the provision of a discharge vessel (2) which is closed off on one side, fitting a second tube over part of the discharge vessel and evacuating and filling the volume of the outer bulb via a pumping hole, which remains open in the second extension part within the second tube. This pumping hole is only closed at the end by means of an operation which closes it by rolling.

Abstract: To provide a universally usable free-piston device with electric linear drive, comprising at least one piston receptacle with at least one piston device arranged for linear displacement in the piston receptacle, the piston device comprising a traveller device, and a stator device being arranged on the piston receptacle, and the at least one piston device being drivable under the action of a medium which expands in an expansion space, it is proposed that the piston stroke be variably adjustable via the linear drive such that the dead centers of the displacement of the piston device are definable.

Abstract: A semiconductor component, in particular a micromechanical pressure sensor based on silicon, having a base layer, an at least largely self-supporting diaphragm and an overlayer situated on the diaphragm, the diaphragm and the base layer, at least from place to place, delimiting a void. Furthermore, at least from place to place, above the diaphragm a conducting region is provided in the overlayer which is electrically poorly conductive as compared to the conducting region, to which the surface of the diaphragm that faces the overlayer is able to be electrically contacted.

Abstract: A method for fabricating a locally reinforced metallic microfeature on a substrate provided preferably with an electrical contacting or a driving circuit, and on an organic, patterned sacrificial layer, which is removed after the metallic microfeature is applied, is described. In fabricating the local reinforcement of the microfeature, at least one further organic layer, formed as a mask, is deposited, which is likewise removed following pattern delineation of the metallic layer.

Abstract: An inside sealing sleeve 1 comprised of an expandable steel band for insertion in leaking pipes in need of repair is provided with an arresting arrangement 4 which permits very small detent steps. For this purpose, the internal band end 2 is provided with a slot 5 having two rows of teeth 8, 9, while a tensioning pinion 10, a guide pinion 11 and a locking pinion 12 are rotatably seated on the external band end 3. A tensioning spring 17 engages the pivot axle of the locking pinion 12, it keeps the locking pinion 12 in engagement with the guide pinion 11 and pushes it into the gap 21 between locking pinion 10 and guide pinion 11.

Abstract: A container for high purity chemicals has a quartz or glass breakseal tube, the end of the tube interior of the container forming a thin annular edge, and a glass or quartz disk fused to said thin annular edge closing the tube. The glass or quartz tube is constructed and adapted to receive, in use, an inner tube disposed in the glass or quartz tube; the disk, glass or quartz tube being of such construction that, in use, the disk is broken off the thin annular edge upon application of force thereto by the inner tube.

Abstract: A system for automatically filling a bubbler, or other vapor delivery system from a reservoir, is disclosed in which the conduit system is purged and pressurized with inert gas, using a unique refill reservoir, level sensing and valving system.

Abstract: A bubbler container for containing and transporting ultra-pure corrosive and poisonous liquid reagents which must be protected from exposure to air and from transmission of gas or vapor through containment walls, means for using the same in connection with unique valving and multiple layer seals for conduits is disclosed.

Abstract: A vacuum vapor transport control system and method for controlling the rate of vapor flow from a reagent reservoir into a vacuum system through an orifice calibrated as to size or flow rate using a high purity fixed gas and vapor provided from multiple reservoirs or mixed vapor provided from a single reservoir.

Abstract: A chemical vessel having improved access means comprising an access tube forming an openable conduit, being closed at the internal end with a discoid breakseal during shipment, a chemical removal tube slidably mounted in gas tight relationship inside the access tube, and means for moving the removal tube into engagement with and breaking out the breakseal for permitting removal of chemical from the vessel is disclosed.
