    Abstract: A closure for a pressure vessel having a collar connectable to the pressure vessel and to a cap, a seal disposed in an area where the collar and cap contact each other, and a plurality of clamping elements for generating the surface pressure between the collar and the cap. The collar comprises an integral sealing flange having an upper flat sealing surface and a lower circumferential annular bead at least partially circular in cross-section. A plurality of C-shaped clamps are displaceably, releasably and form-fittingly held on said lower circumferential annular bead. Each C-shaped clamp comprises one pressure screw and constitutes a clamping element. In the operational state of the closure, the C-shaped clamps press on the edge region of the cap resting on the sealing flange of the collar.

  • Patent number: 5427014
    Abstract: The cooking vessel comprises a container (1) and a lid consisting of an inner lid (3) and an outer lid (5). The container comprises a bent peripheral container rim (2) wherein twelve individual hook-like lock elements (21) are effective locking the cooking vessel. The lock elements (21) are arranged peripherically and swivellingly along the inner lid rim (4) so that through pressing the upper lid (5) against the lock elements (21) a swivel movement of said lock elements is obtained. The lock elements are C-shaped with a hook part (32), such that in the swivel position corresponding to the closed state, the ends of this hook part (32) grip under the outer container rim (2). In the swivel position corresponding to the opened state, the ends of said hook part (32) are in a distance from said container rim (2) allowing an unhindered lifting of the inner lid (3) from the container (1).

  • Patent number: 5370254
    Abstract: Hinge and latching mechanism for containers having a cover and a base includes a latch which, at its upper portion, is shaped to hook over a strike integrally disposed on the cover. The lower portion of the latch rotates about a pin located between a pair of feet which are provided with hooks to engage a flange extending from a lip on the base. The hinge includes a body and two legs and the former is also shaped to securely engage a second strike also located on the cover. Each leg has a foot which is also hooked to engage the flange of the base. To further secure the hinge and latch, each hook is fastened together and to the container. This structure ensures that hinge and latching mechanism are especially adapted for heavy duty applications while still being light in weight and small in size.

  • Patent number: 5361925
    Abstract: A terminal box includes a base and a cover detachably securable to the base. The cover is provided with a stepped bore in each corner area thereof, with a spring-loaded locking bolt being insertable therein and slideable in axial direction in opposition to the spring action for securing the cover to the base. Each locking bolt has one end provided with a blade-like expansion which is created through flattening this respective end of the locking bolt. In the area facing the base, the cover is provided with radial slots which are in alignment with radial slots of the base and suitably dimensioned to receive the blade of the locking bolts. When placing the cover upon the base, each locking bolt is pressed down through the bore and radial slots in the base and turned to allow the blade of each locking bolt to bear upon an abutment of the base for securement of the cover to the base.

  • Patent number: 5293813
    Abstract: A cooling vessel has a container with an outwardly bent rim and a lid which can be set on the container, as well as a closure device with at least one closure element arranged on the lid, preferably in the region of a rim of the lid. The closure element can swivel about a swivelling axis approximately parallel to an outer edge or to tangent to the outer edge of a rim of the container from an open position which releases the lid from the container into a locking position in which the closure element grips under the container rim, thus forming a pressure-tight seal between the lid and the container. The closure element is designed as a hollow body with an essentially cylindrical or prismatic wall essentially parallel to the direction of the swivelling axis. The wall extends over only a part of the periphery of the hollow body and has a locking wall section which can be pivoted from an open position into a closing position. The closure element rests on a shaped body.

  • Patent number: 5201157
    Abstract: A pole top cover assembly includes a generally flat cover plate adapted to overlie an open top end of a tubular hollow pole, an elongated arcuate-shaped bracket formed of yieldably resilient, semi-rigid, semi-flexible deformable material and being disposable along one side of the cover plate, and an elongated fastener rotatably mounted through both an aperture in the cover plate and a hole in the bracket and having external threads threadably engaged with portions of the plate and bracket which form the respective aperture and hole thereof. Rotation of the fastener in one direction relative to the cover plate and bracket causes the arcuate-shaped bracket to engage the plate and to deform and draw toward the one side of the cover plate and thereby expand in length and forcibly engage at opposite ends with portions of an interior surface of the hollow tubular pole so as to retain the cover plate on the pole top end.

  • Patent number: 5099823
    Abstract: A humidifier unit is used with a forced air heating system and includes a water reservoir, a water inlet connection to the reservoir, control means for maintaining the water level at a predetermined depth, and a heat exchanger for heating the water to produce steam. This reservoir has a removable top plate for closing the open top defined by the upper edges of side and end walls. Horizontal flanges extend inward from the upper edges of the reservoir side and end walls and act as a gasket base. Lips extend upward from the inner edges of those horizontal flanges and act as an internal horizontal gasket retainer. Finally, flanges depend from all sides of the top plate and are positioned to surround the upper edges of the side walls and to act as an external horizontal gasket retainer.
