A transistor outline package is provided that includes a header with a mounting area for an optoelectronic component. The header has a signal pin disposed in a feedthrough. The feedthrough is filled with an insulating material made of glass and/or glass ceramic. The feedthrough has a recessed area on at least one side that is not completely filled up with the insulating material. The recessed area defines a cavity at least partially around the signal pin and the signal pin has an enlarged portion in the recessed area.

A lead-through or connecting element is provided that includes an assembly having a carrier body of a high-temperature alloy, a functional element, and an at least partially crystallized glass. The crystallized glass is between a portion of the functional element and a portion of the carrier body. The carrier body subjects the crystallized glass to a compressive stress of greater than or equal to zero, at a temperature from at least 20° C. to more than 450° C. Also provided are a method for producing a lead-through or connecting element, the use of such a lead-through or connecting element, and to a measuring device including such a lead-through or connecting element.

A feedthrough assembly and methods of making the feedthrough assembly are shown. A feedthrough assembly including a ferrule disposed about an insulator and having an outer surface and a first aperture defined by an inner surface, wherein the first aperture is sized and shaped to include a reservoir for a braze material, the reservoir including a base, the base having a width sized to accommodate a preform of the braze material, and at least two ledges formed by the inner surface, each ledge having a first surface facing inwardly toward the insulator and a second surface facing upwardly is shown. Methods of making the feedthrough assembly including such a ferrule are shown.

A high-voltage bushing has an internal conductor and an insulating body which surrounds the internal conductor along its longitudinal direction. The internal conductor is routed out of the insulating body at a head end of the high-voltage bushing. A fastening flange is arranged on the insulating body at an end opposite the head end. An outer housing encloses the internal conductor and the insulating body from the fastening flange up to and including the head end in a moisture-tight manner. A high-voltage installation has a high-voltage conductor which is routed through a housing wall of the high-voltage installation by way of the novel high-voltage bushing.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

An insulating device includes a body portion including a first surface feature extending between a first surface end and a second surface end. The first surface end defines a first surface cross-sectional size. The second surface end defines a second surface cross-sectional size. The second surface cross-sectional size is less than the first surface cross-sectional size. The body portion includes a second surface feature extending between a third surface end and a fourth surface end. The third surface end defines a third surface cross-sectional size. The fourth surface end defines a fourth surface cross-sectional size. The fourth surface cross-sectional size is less than the third surface cross-sectional size. The insulating device includes a flange portion having a flange wall. The flange wall includes a first mating portion that engages the first surface feature and a second mating portion that engages the second surface feature of the body portion.

Contact pins for glass seals is provided having an iron alloy and a method for their production. The contact pins are provided with a nickel layer and coated with rhodium and/or platinum or with palladium. The contact pins may be additionally provided with a layer of gold. The contact pins are first cleaned by degreasing and activating, preferably by activating through acid etching. Thereafter, the application of a nickel layer is performed under a protective gas atmosphere, followed by formatting at 850 to 1050° C. The protective gas atmosphere is preferably made up of 10 to 100% hydrogen, with the balance formed of nitrogen. This is followed by a coating with palladium or with rhodium and platinum, or with platinum, or with rhodium and gold.

Disclosed herein is a gel seal including a volume of gel between first and second end plates. The first and second end plates have one or more cable ports with a central longitudinal axis extending through the first end plate, the volume of gel, and the second end plate. The cable port has a first, circular cross-sectional profile in the first and second end plates for receiving a round cable and a second, elongate cross-sectional profile in the first and second end plates for receiving a flat cable.
