Abstract: An illuminated advertisement type display comprising an open front housing that is closed by a transparent panel of plastic or the like which has a display printed thereon simulating a neon sign. Within the housing, there is a fluorescent light bulb that provides illumination for the printed display. The printing is by "transparent" pigment that may have incorporated therein translucent substances in small amounts, but sufficient to occlude the vision of the fluorescent light bulb to a viewer of the display. Surrounding the printed display is a coating of opaque material, so that the areas surrounding the printed matter is black. This coating may be a high reflecting aluminum foil which also reflects light produced by the fluorescent light to increase the light transmited through the panel.

Abstract: Known extrusion presses create elastic oscillations that result in chatter cracking when the metal being extruded is a high strain rate sensitive material. This invention removes that problem by placing the tie rods of the press in an initial pre-tension of a magnitude greater than the maximum tie rod stress that will be caused by the flow of metal through the extrusion die, and holding the thrust of the pre-tension by cast iron columns of such cross sectional area that the linear compression of the columns due to the thrust of that pre-tension is negligible.

Abstract: The invention relates to a hang-up fixture for ceiling mounting adapted to have a twist-lock releasable connection with a ceiling element to provide a support for a hanging article such as a display sign, or banner in a store, or a hanging plant, or lamp, or the like.

Abstract: Metal billets to be used for extrusion are cast and quickly cooled to their solidifying temperature to minimize grain growth and are delivered to a tempering oven where they cool to the temperature required for extrusion, thus also evening the temperature of the billet. They are kept at that temperature until taken to an extrusion press one at a time where the billet is maintained against cooling from its extrusion temperature throughout the extrusion time. The billet is of such size and shape that the time between the first solidification of the outer surface and the last solidification of the inner liquid metal thereof is not so great as to cause excessive grain structure. In the extruding machine, the tie rods that resist the extruding pressure are prestressed to prevent appreciable dimensional variations in the press due to normal variations in the extruding pressure.

Abstract: This invention relates to a pressure/vacuum system apparatus; one part of such apparatus being an economical fitting, another part being operating mechanism, another part being a means to join such fitting to such operating mechanism in a substantially fluid-tight manner, all operable to perform certain functions together without shutting down the pressure/vacuum system they are attached to. Some installations require many fittings. In many instances an operating mechanism may be attached to an operated fitting for only short periods of time and then disconnected therefrom, leaving the operated fitting in (a) a dormant condition in relation to its functions to the pressure/vacuum system, or (b) in a functional condition in relation to the pressure/vacuum system. Thus, in many cases a single operating mechanism may be used for operating each of a number of different fittings from time to time as required.

Abstract: A bicycle handlebar stem is made of two separate parts, a tubular shank and a gooseneck. This eliminates or substantially reduces long drilling operation for the stem and it simplifies the forging of the gooseneck. The gooseneck is shaped for forging thereof in a manner such that the meeting of the forging dies does not occur across the top of the stem, and the forging operation can forge identifying insignia on the stem top and/or form a recess of receiving an identification plate. Destruction of the indicia on the plate in the case of a stolen bicycle is easily detected. In order to inhibit commerce in such stolen bicycles the handlebar stem is mounted in the steering column in a manner that requires a special tool to remove it and to replace it by another.

Abstract: A suspension hanger suspending a light weight point of purchase display in a manner that will permit swinging and turning of the display by slight air currents that are normally present in the surrounding atmosphere, and which will permit simple lowering of the display in the initial installation, or thereafter, to bring it to its desired height. The suspension consists of a vertical helical spring by which the display is suspended to permit oscillation of the display about a vertical axis, the spring being of a small diameter to permit swinging of the display, and being of a material of a low modulus of elasticity so that upon the exertion of a comparatively small pulling force in excess of the weight of the display the spring is stretched beyond its elastic.

Abstract: This invention relates to a display which is used to convey information or attract attention at a point of purchase of products. The display includes means for receiving and holding two or more display sheets in a balanced relationship. It includes essentially a rod-like central structure, having two or more socketing arms symetrically spaced and each adopted to receive and hold a display panel or other eye-catching object. The central rod has means at one end thereof for suspending it and alternate means at the opposite end for mounting it on a pole or column, in a manner such that it may oscillate or swing, thereby producing a mobile effect.

Abstract: A drink shaker for mixing solids, and particularly those that tend to lump, and liquids, to mix beverages. The shaker comprises first and second containers of tumbler configuration, and a basket member formed to have its side wall and floor of a foraminous character. The basket member is to receive the solids to be mixed into the liquids of the drink and the basket member is formed to rest within the first container on a ledge structure provided for that purpose. The basket member is also formed for friction fit reception and retention within the second container. The second container is formed for a plug fit liquid sealing securement application within the first container. The basket member is shaped to provide for movement of the liquids on shaking into the second container for application to the solids in the basket member from both sides of same.

Abstract: An apparatus and method for measuring the thickness of a protective film on a sheet or substrate as the sheet moves past the apparatus. The apparatus includes a black-body radiator in the form of an isothermal cavity having an opening across which the sheet is moved. The cavity has an observation window opposite the opening through which window the surface of the moving sheet may be scanned. A radiation pyrometer scans the moving sheet through the observation opening. Rays from the radiator pass through the film to the substrate, are reflected by the substrate, and pass back through the film and through the window to the pyrometer. The absorption of rays from the black-body radiator as they pass through the film is a function of the thickness of the portion of the film being observed. The radiation pyrometer thus receives an output which is a function of the film thickness being measured.

Abstract: A surface grinder having a grinding wheel mounted on a support and means for elevating the grinding wheel relative to a workpiece. A wheel dresser apparatus is mounted on the grinding wheel support. The wheel dresser apparatus includes a coarse adjustment means and a fine feed adjustment means for selecting the depth of dressing cut. Compensating means connects the fine feed adjustment means with grinding wheel support to move the grinding wheel towards the work the same amount as the depth of dressing cut.
