Abstract: A glass-to-metal hermetic seal assembly in a sight glass assembly or a hermetic terminal assembly is disclosed and includes a glass component, an intermediate component, and an outer ring. The intermediate component is provided around the glass component. The glass component is fused to the intermediate component. The outer ring, which has a coefficient of thermal expansion that is greater than a coefficient of thermal expansion of the glass component, compresses the intermediate component against the glass component to create a hermetic compression seal.

Abstract: A hermetic terminal assembly includes a terminal body and terminal pins extending through the terminal body. The terminal pins each have a first end configured for connection to a power source disposed outside of a hermetic compressor and a second end configured for direct connection to motor windings disposed within hermetic compressor.

Abstract: A power terminal feed-through includes a housing, at least one current conducting pin and a sealing glass hermetically sealing the at least one current conducting pin to the housing. The at least one current conducting pin defines a peripheral indentation in the surface of the current conducting pin. The sealing glass fills in the peripheral indentation when fused to both the current conducting pin and housing.

Abstract: A power terminal feed-through incorporates a metallic body through which extend one or more current conducting pins that are hermetically sealed to the metallic body by a glass-to-metal seal. The metallic body includes an annular lip with a protrusion. During welding installation of the power terminal feed-through, the protrusion serves to assist in the welding process, better controlling the location and definition of the weld between the metallic body and a housing, and to focus the welding heat at the protrusion, thereby protecting the glass-to-metal seal. The glass-to-metal seal can be a single glass insert through which the current conducting pins extend, thereby reducing the pin circle diameter and the overall size of the power terminal feed-through.

Abstract: An improved lower cost sight glass and a method for producing the same is disclosed, whereby the sight glass is made by placing a transparent component in secure contact with a metallic ring. The contact may optionally be effectuated by temporarily altering the relative dimensions of the metallic ring and the transparent component, placing the transparent component into the inner space of the metallic ring, and then reversing the altered relative dimensions of the metallic ring and the transparent component. A hermetic seal is formed between the transparent component and the metallic ring is by the application of an inorganic sealing compound.

Abstract: A conductive pin assembly arrangement for a wall opening of a machine housing including a removable plate in sealed relation to the wall opening, the plate having at least one opening extending therethrough, and a conductive sleeve and pin assembly extending longitudinally through the plate in sealed relation to the plate with one end of the pin in the housing and the opposite end outside the housing.

Abstract: A pressure release safety vent arrangement for an ingredient container including an opening extending through one portion of the container and a preselected separate profoundly rupturable foil membrane fastened in covering and sealing relation to the opening, the membrane being selected to profoundly tear away and rupture to vent the container under a selected pressure.

Abstract: A hermetic terminal assembly arrangement for an opening extending through a wall housing panel wherein the opening periphery is threaded to adjustably receive an externally threaded annular sleeve through which a current conducting pin extends, the terminal assembly arrangement including a first seal between the pin and annular sleeve and a second compressible seal between the sleeve and housing.
