Abstract: Apparatus for forming a cased glass stream that includes at least one pair of aligned orifices coupled to sources of core and casing glass such that glass flows by gravity from the glass sources through the aligned orifices to form a cased glass stream. The orifices are carried by an orifice housing mounted on a frame for movement into seating engagement of the orifice housing against the core and casing glass delivery mechanisms. A fluid manifold is mounted on the orifice housing, with an inlet for connection to a source of cooling fluid such as air. A plurality of outlets on the manifold are directed toward the area of seating engagement between the orifice ring housing and the core and casing glass delivery mechanisms for cooling the seating area and thereby reducing leakage of glass between the housing and the glass delivery mechanisms. Inasmuch as the cooling air manifold is mounted on and carried by the orifice housing, the manifold outlets are automatically directed toward the seating area upon seating of the orifice housing against the glass delivery mechanisms, and do not require separate replacement or adjustment.

Abstract: A plastic bracket with a central opening is slidably positionable on a rearwardly extending mounting arm of an inverted L-shaped bicycle support member which is mounted to an automobile. The mounting arm has an axially extending spline which extends from the front of the mounting arm to a position spaced from the rear of the arm. Multiple recessed keyways are formed in the bracket around the central opening. A keyway mates with the spline, and restricts the rotation of the bracket when a toggle is operated to clamp the bracket against axial movement. Bicycles supported on the bracket by two pivotable tube holders are thus securely connected to the mounting arm, but are selectably positionable to allow multiple bicycles to compactly fit on the arm. Skis may also be attached to the bracket.

Abstract: The present invention teaches an efficient and easier to operate distillation system to separate mixtures containing three or more components into streams enriched in one of the components. In this invention, a liquid stream enriched in the least volatile component is withdrawn from the bottom of one distillation column while a vapor stream enriched in the most volatile component is withdrawn from the top of another distillation column. Of these two distillation columns, the pressure of the distillation column with the bottom liquid enriched in the least volatile component is higher; and this higher pressure distillation column transfers at least two vapor streams from different locations to either one or more other distillation columns within the distillation system. For a ternary mixture, both the vapor streams are transferred to the distillation column with the top vapor enriched in the most volatile component. In the preferred mode, at least one of the vapor transfer is part of a two-way communication between the two columns, i.e., in addition to the transfer of the vapor stream, a return liquid stream is implemented between the same locations of the two columns. This invention allows the flow of all vapor streams from a higher pressure column to a lower pressure column and thereby does not suffer with the operating pressure constraints of the prior art efficient processes.

Abstract: A scalpel having a blade with a fitting molded about or assembled to its proximal end with the fitting having a proximally facing opening sized to receive an end of a distal portion of a detachable handle. The handle includes a proximal portion designed to be gripped by the surgeon and a distal portion including a male coupling half designed to be received within the proximal opening of the fitting, which proximal opening is configured as a female coupling half. The proximal and distal portions of the handle are angled with respect to one another defining an angle from about 0°-10°. The male coupling half may be inserted within the female coupling half in either one of two diametrically opposed orientations. Thus, due to the angulation between the proximal portion of the handle and the distal portion of the handle, the proximal portion of the handle is either angled downwardly or upwardly with respect to the axis of the blade itself. The handle may be attached to the blade in either one of these two positions depending upon the particular surgical step that is being carried out by the surgeon. The blade itself is provided with a double grind which enhances the sharpness and longetivity of the blade.      In the preferred embodiment, the blade includes a primary grind defining an angle of 6°-10° per side and a secondary and final grind of 14°-18° per side. The blade itself is made of a thickness of from 0.020 - 0.029 inches, and, if desired, the cutting surface of the scalpel blade may be coated with a very thin layer of zirconium nitride or other coating material as disclosed.
