Such a construction enables the testing of a progressively hardening material without having to separate the material from the container as soon as the tests are finished.

Abstract: A plastic sealing ring is attached to a rim of a plastic container with an insert interposed between the rim and the sealing ring. By making the insert from a relatively rigid material, the insert can rigidify the sealing ring and hence the container. If the insert is made from an electrically conductive material, the insert can function to facilitate the induction welding of the sealing ring to the container. The sealing ring and insert can be formed as a unitary, composite sealing ring subassembly adapted for direct application to the rim of the container or they can be supplied as individual parts adapted to be applied to the rim of the container separately. In order to form the sealing ring subassembly, the sealing ring is molded from molten plastic. During the cooling of the sealing ring, the insert is positioned in a groove formed in the sealing ring.

The dual draft channels are controlled by an automatic draft device at the front of the stove through which the draft air is introduced. A heat shield at the rear of the stove cooperates with the one piece base for delivering heated air forwardly to the living area in front of the stove.

Abstract: A box for storing and dispensing food-stuff distributed upon a foil band and wound to a spool upon a shaft comprises two like components, each defined by a base plate and three adjoining walls. Each wall is provided with an open slot starting from the edge of the pertaining wall remote from the base plate and extending about half-way down towards the latter, whereby the two components become sufficiently deformable to permit a fitting together, to form either a closed box, or a stand presenting an open front for serving-out purposes.The slots in two oppositely located walls are formed to carry the ends of the shaft and the slot in the intermediate wall preferably is deeper than the slots in the first mentioned walls.A box of this type may be fitted in an apparatus having a rotatable drum for coiling up the wasted foil band, as this is pulled out of the spool, to make the food-stuff available.

Abstract: A cabinet is disclosed having a front frame constructed from four extruded edge members. Each extruded edge member has a running slot internal to it such that it receives a reinforcing member at each corner. The outer enclosure comprises an upper U-shaped panel and a lower U-shaped panel, each having interiorly bent outer edges which are secured by a dove-tail bent clamp positioned therebetween. A rear frame secures the enclosure in wrap-around relationship to both front and rear frames. Interior mounting posts having mounting holes thereon are secured to the front and rear frames by means of a fastener which engages a second running slot adjacent the first. The panels coupled with the mounting members secure the frame members which are reinforced at their corners and the dove-tail bent clamp secures the upper U-shaped closure portion to the lower U-shaped closure portion. The dove-tail bent clamp also forms horizontal handle assemblies on both sides of the cabinet.

The first and second sections are preferably identical separate parts which are interengageable.

Abstract: A cooking pan assembly is provided which has particular utility in the industrial cooking of food, such as tuna fish. The cooking pan is particularly constructed so that it may conveniently be transported on usual conveyors within the cooking facility. Crimped wire-formed ends are provided for the pan which serve as handles and which prevent the contents of the pan from sliding through the front or rear ends thereof. The wire-formed ends are crimped loosely to the side walls and bottom of the pan for sanitary reasons so that there is only a point contact between the wire-formed ends and the sides and bottoms, and no areas are formed which would be conducive to build up of bacteria. There are no welds between the end members and the bottom or side walls of the pan, since such welds would produce two separate surfaces in intimate contact with one another which could harbor bacteria. The pan assembly is easy to clean thoroughly by a simple spray wash since there are no nooks or crannies in the assembly.

Abstract: An enclosed modular circuit component is immobilized against deleterious movement due to high impact, shock and vibration movement. A two-piece enclosure case for securely immobilizing a wide variety of readily available modular circuit components is easy to fabricate and utilize with the components. The enclosure case comprises two halves each of which has a top and a bottom, respectively, with two oppositely disposed side walls projecting therefrom. At least one half of the case has a ledge upon which the circuit component header, such as an element support board or a printed circuit board, may be supported. The other half of the case is then provided with means to urge the board against the ledge so that when the two halves are placed together the component is sandwiched between them in a secured immobile relationship. The component elements may be maintained spaced from contact with the enclosure interior surfaces.
