Abstract: A resilient, yieldable, nestable, tapered, foamed thermoplastic container or cup is provided each cup or container having an endless groove and endless lug extending from the inside and outside surfaces of the container or cup wall, the groove penetrating the container or cup wall. The endless lug extends a distance from the cup wall greater than the distance the groove penetrates into the cup wall by about several thousandths of an inch (a few thousandths of a centimeter).

Abstract: A climbing rung for anchoring to the wall of a manhole shaft. The climbing rung has a generally U-shaped core of two parallel legs spaced apart by a central tread. Each leg is sheathed in a pre-formed protective sleeve, closed at one end, by inserting the leg into the mouth of the sleeve. An injection moulded protective coating is bonded to the core of the tread and the core of each leg, extending to proximate the mouth of each pre-formed sleeve when a leg is sheathed therein, forming a sealing interface proximate the annular lip circumferentially defining the mouth of each sleeve. A method includes gripping the climbing rung only proximate the pre-formed protective sleeves when both legs are sheathed therein, so as to permit positioning the core of the tread and legs, extending only to proximate the mouth of each pre-formed protective sleeve, in an injection moulded cavity radially spaced equidistant the surface of the mould cavity.

Abstract: An improved preheater is provided suitable for use with gas or oil fired reverberatory melting furnaces for recycling aluminum scrap and other scrap metals. The improved preheater comprises a charge box having a bottom, and a chamber having a bed. The chamber is in communication with the charge box at one end, and, an exit at the other. A pusher is provided for pushing the contents of the charge box into the chamber and thus pushing the contents of the chamber towards the exit. The chamber is of uniform expanding dimensions from its one end in communication with the charge box towards the exit. The bed of the chamber carries openings therethrough from a gas chamber therebelow into which heated waste gas is passed for circulation through the openings in the bed through the contents of the chamber.

Abstract: A u-shaped climbing rung to be anchored in a bore hole in a wall, the climbing rung being two parallel legs each leg having two ends, one end of each leg being connected to a transverse central element or tread spaced a predetermined distance below the parallel legs and having the other end for anchoring in a wall, the legs and tread being completely encapsulated in a synthetic protective coat having an outer configuration adapted to present each end of the legs remote the tread for anchoring the climbing rung in the wall, each encapsulated end having an anchor for anchoring the end of each leg, in a wall, and two soft elastic and tightly fitting sealing collars located on the legs spaced from the end of the legs securely anchored in the wall to frictionally slide along the legs to present a sealing face to an abutting wall deforming when abutting the surface of the wall to accommodate the surface configuration of the wall surrounding the bore hole whereby the combination of the anchor for securely anchoring

Abstract: Novel pharmaceutical solutions and particularly novel pharmaceutical solutions comprising dimethyl sulfoxide (DMSO).

Abstract: A seat assembly especially suitable for use as a front seat of a two door vehicle. The seat assembly is slidable on tracks for permitting ease of access to behind the seat, and is provided with a front and rear end comprising three track assemblies, a fixed lower track assembly, a middle or second track assembly releaseably secured to the lower track assembly, and when released, being slideable to the front end with respect to the lower track assembly, and an upper or third track assembly releaseably secured to the middle track assembly, and when released, being slideable to the front end with respect to the middle track assembly. The seat assembly includes a "memory" for returning the slideable set assembly to its initial position.

Abstract: A panel is provided for use in a sound absorbing wall structure. The panel includes a front of wood based material having perforations, a back parallel with the front and separated from the front. Sound absorbing material is positioned in engagement with the front within the space covering the perforations so that the panel absorbs sound directed at the perforated front of the panel by absorption in the material of the front as well as in the sound absorbing material.

Abstract: A gutter section of plastics material comprising front and rear walls and a bottom, the front and rear walls carrying fastening elements for being removably secured to complementary fastening elements of a hanger bracket and a raised bead or projection on the inner surface of the rear wall extending in the same direction as the top of the rear wall and spaced therefrom whereby when a hanger bracket is secured to the gutter section, a hanger bracket engages the bead or projection on the rear wall of the gutter to rigidify the structure and permit ease of expansion and contraction of the gutter section relative to any hanger brackets supporting the gutter section.

Abstract: A bar has at least one compartment, a plurality of removeable magazines mounted in the compartment, fiber optics associated with the bar compartment and each magazine for assisting to detect the removal of a magazine from the bar compartment and the removal and/or movement of the contents of the magazine. The fiber optics comprise:(a) optical fibers secured to each magazine and lenses secured to the optical fibers on each magazine; and(b) lenses on the bar associated with the compartment. Some of the lenses on each magazine are spaced from, and aligned with, some of the lenses on the same magazine for the transmission of light therebetween, and some of the lenses on each magazine are spaced from, and aligned with, some of the lenses on the bar associated with the compartment for the transmission of light therebetween.

Abstract: Novel pharmaceutical solutions and particularly novel pharmaceutical solutions comprising dimethyl sulfoxide (DMSO).

Abstract: A method and apparatus for desolventizing residual solids after the oil or fat is extracted therefrom, wherein oil-bearing vegetable or fatty animal material has its oil or fat extracted by an extraction solvent to form an oil or fat solvent mixture, referred to as a "miscella," and extraction solvent impregnated residual solids. The oil or fat is separated from the miscella by heat and vacuum produced by ejector steam, which ejector steam acquires extraction solvent vapor as a result thereof. The solvent-vapor laden waste ejector steam, in conjunction with additional steam from a boiler system, is applied directly to the extraction solvent impregnated residual solids. The combined solvent-vapor laden waste ejector steam and boiler steam evaporate the extraction solvent from the impregnated residual solids and desolventize them to render them fit for consumption or other industrial processes.

Abstract: The present invention relates to a glass pane whereby a broken pattern of white and black opaque material is applied to the surface or surfaces of the glass pane such that concentrated light from one side of the glass is reflected to such an extent that persons on that side of the glass may see the wall and may "read" the path of an object moving relative to said wall whilst persons disposed on the other side of said wall may see through the wall to a sufficient extent to also follow the path of said moving object. The glass panels of the present invention are particularly suitable for wall members for a squash, handball, racquet-ball or like court.
