  • Patent number: 5823685
    Abstract: A bag closure is provided for containing flowable material such as powdered cement and mortar. The closure includes loosely folded, overlapping end flaps which are secured together by an overlying peel-away sheet. Where the bag is to be filled with moisture sensitive materials, the peel-away sheet is preferably impermeable to water vapor and forms a vapor barrier closure. The peel-away sheet, which preferably controls the moisture content within the bag during storage, includes a graspable tab that is used to peel the sheet at least partially away from the loosely folded flaps of the bag. An end tuck of the bag may then be unfolded to provide a pour spout for the contents of the bag. The closure eliminates the need for prior art pull strings or sewn ends which are not easy to open and which do not adequately resist moisture penetration.

  • Patent number: 5791700
    Abstract: A locking system for a window sash comprises a lock handle assembly, reciprocating rod members connected to the lock handle assembly, and rotatable cam assemblies connected to the rod members. Each cam assembly has a cam element which upon reciprocation of its respective rod element moves into and out of a cam keeper which is mounted on an adjacent window sash. Each rod member has a rod tip which moves into and out of a channel provided in the window frame. In a first operation of the lock handle assembly, the rod members are reciprocated inwardly to rotate the cam elements out of their respective cam keeper and to move the rod tips partially out of the frame channels which allows the window sash to be moved vertically within the channels. A further operation of the lock handle assembly moves the rod tips entirely out of the channels to allow the window sash to be tilted.

  • Patent number: 5744254
    Abstract: Composite materials are disclosed comprising a continuous matrix with composite reinforcements therein. The composite materials may include a continuous metal, metal alloy or intermetallic matrix with intermetallic matrix composite reinforcements dispersed therein. Suitable metals for the continuous matrix include Al, Ti, Cu and Fe, and alloys and intermetallics thereof. The composite reinforcements comprise ceramic particles dispersed in a continuous intermetallic matrix. Suitable intermetallics include alumnides of Ti, Cu, Ni, Mg and Fe, while suitable ceramics include refractory metal borides, carbides, nitrides, silicides and sulfides. In one embodiment, the ceramic particles are formed in-situ within the intermetallic matrix of the composite reinforcements. The composite materials are produced by powder metallurgical techniques wherein powders of the continuous matrix component and powders of the composite reinforcement are blended and consolidated.
