A sealed container eventually shaped into a rectangular parallelopiped is formed by folding a sheet of blank and joining together the required folded portions. The container has a longitudinal seal portion formed by joining together the longitudinal opposite edge portions of the blank and extending vertically over the rear side of the rectangular parallelopipedal container main body, and upper and lower transverse seal portions formed by sealing the upper and lower ends of the blank as shaped in...

A sealed watchcase includes a middle-and-bezel having two concentric annular parts which are held one inside the other by means of friction. The internal part of these two parts is a rigid ring made of ordinary metal or plastic. The external part of these two parts is made of precious-metal and forms a thin casing covering at least the radially external surfaces of the rigid ring. A glass part is bonded inside an internal snap in the precious-metal casing. A back cover is held against a bottom f...

A movable machine element extends through a housing and defines a gap therewith. A supply line communicates with the gap at an intermediate point of the length thereof and is adapted to supply liquid sealing fluid to the gap. Cooling means are provided to cool the sealing fluid in the gap below its solidification point on both sides of the intermediate point.

A double-sealed package including a container with an inner cover member spanning its open end. An outer cover is sealed to both the container flange and the inner cover member. The method includes pressure forming the container and inner cover member, depositing a material in a container, placing the inner cover member in position, and sealing the outer cover to both the container and inner cover member.

The invention comprises a carburetor having a controller in the fuel line feeding the main carburetor venturi to seal the fuel system against evaporative losses. The controller comprises two diaphragm operated valves arranged in cascade series. A throttle-actuated pump is also provided to operate the diaphragms to open the valves simultaneously and quickly for fast acceleration.

A bag is constructed of interconnected panels each of which comprises a pair of vinyl cover sheets enclosing a fiber glass filler. The outermost edges of the cover sheets are electronically sealed to one another to trap the filler between the cover sheets; and a further electronic seal is provided between the cover sheets inward of the outermost edges thereof and extending through the fiber glass filler to keep the filler from shifting or bunching up.

A container assembly as a lid for closing and sealing the open end of the container. The container includes an outwardly curled sealing lip at its upper most periphery. The lid includes a rim having inner and out legs, and a bridge or web connecting the legs. The legs and the bridge define a downwardly opening channel proportioned to fit over the lip of the container. The legs, bridge and the lip cooperatively define therebetween a sealant cavity or the cavity may be formed only in the bridge. T...

A sealed linear encoder for determining the relative position of a first object and a second object. The sealed linear encoder includes a scale unit arranged in a hollow body that is mounted to a mounting structure associated with the first object and includes a slot which extends in a direction of measurement. A scanning unit for scanning the scale unit and a carrier connected to the second object, wherein the carrier extends through the slot. Sealing lips arranged at the hollow body and abutti...
