Abstract: A thermally bonded fibrous product is composed of a sintered blend of ceramic fibers, low-grade silica material and boron nitride.

Abstract: A thermally bonded fibrous product is composed of a sintered blend of aluminosilicate fibers, silica powder and boron nitride powder.

Abstract: A pistol that has a barrel and bolt is provided and consists of a mechanism for revolving a cylindrical magazine that has a plurality of radial chambers which hold a plurality of cartridges within a cylindrical bore of a handle. Each chamber in turn will be in alignment with the barrel and the cartridges in turn will be in position to be pushed by the bolt to be fired from the barrel.

Abstract: A fiber-free refractory coating composition consisting essentially of an aluminosilicate mineral selected from the group consisting of kyanite, andalusite, and sillimanite; alumina; colloidal silica; and water. This mixture is characterized by good adhesion to substrate material, and excellent resistance to thermal shock and chemical attack through a wide range of firing temperatures up to 3000.degree. F.

Abstract: Handle attachment for vessels such as drinking cups formed from a metal stamping, and for lids comprising a hinge-lever integral therewith. Said attachment comprising a rectangular member which extends into a rectangularly perforated tongue with a thin band of metal along its upper edge; and three pairs of tabs along the length of the member which attaches the U-shaped handle to the member.

Abstract: For vessels such as drinking cups formed from a metal stamping, having a rim formed by crimping the vessel lip around a length of wire, a U-shaped loop of which protrudes from two slots in said rim and is bent to form a handle, a new vessel lid attachment is provided which includes a hinge pin fashioned from a second length of wire which connects both sides of said U-shaped loop near the rim of said vessel, a hinge formed by an extension of said lid, having two parallel tabs which are slotted to slide over said hinge pin, said hinge also serving as a thumb operated lever for lifting said lid.

Abstract: A process for slicing boules of a single crystal material such as gadolinium gallium garnet (GGG) into wafers is described. The boule is prepared, by grinding preferably, so that the longitudinal boule axis corresponds to the crystallographic orientation axis of the boule. The boule is then mounted in a fixture and aligned so that the common longitudinal axis and crystallographic orientation axis is perpendicular to the saw blade. The boule is then rotated while maintaining the orientation of the combined common axis and engaged against an inner diameter rotating saw blade for a time sufficient for the blade to slice through the boule and form a wafer. The wafers obtained by this slicing process may be directly polished without the conventional lapping step to form a wafer having a surface that is substantially flat, parallel and defect free.

Abstract: In a wedge-type vehicle brake actuator with a cage assembly unattached to the wedge member the travel of the cage assembly is limited by an engagement with one follower member. With an assymetric cage assembly the assembly of the cage assembly into the housing is prevented by an engagement with a follower member when the cage assembly is assembled the wrong way.
