Abstract: The present concept is an electrically heated refractory mandrel which includes a mandrel shell including a top surface, side surfaces and a bottom surface. An interior frame work is mounted within the mandrel shell and defines a number of openings. Heater panels are dimensioned to fit within the openings defined within the interior frame work wherein each heater panel includes heater elements for heating preselected surfaces of the mandrel shell.

Abstract: An illuminating goal structure is disclosed. According to one embodiment of the present invention the illuminating goal structure, adapted for connection to a power source, includes a back plate, a face plate having at least one lighting aperture defined therein, viewable signal means (VSM) housed within the at least one lighting aperture, connection means for operably connecting the VSM to the power source, and VSM control means for controlling the distribution of power from the power source to the VSM, wherein the back plate is attached to the face plate such that the connection means are enclosed therein.

Abstract: The invention relates to the fabrication of panels, trays and other assemblies from fibreboard or other sheet material by folding-back edge portions of the sheet to provide marginal portions of increased thickness and substantially uniform width of which the inner edges define retaining abutments, each marginal portion being located in a channel of respective channel-shaped edging strips each having a lip or rib which engages over and with the retaining abutment of the marginal portion to resist separation of the strip from the edge of the sheet in the direction perpendicular to said edge. The edging strips are assembled to an edge by forcing the channel over the marginal portion. Adjacent edging strips engage to resist sliding movement.

Abstract: A package for at least one diskette having a computer program recorded thereon. The package is formed of a planar sheet of paperboard which has been cut to a shape and folded along predetermined lines. The package includes a base panel on which the diskette is disposed, a pair of flap panels, each being folded along respective fold lines over a portion of the base panel and the diskette, and a first cover panel folded along a respective fold line over the base panel and the flap panels. Each of the flap panels comprises at a first portion having indicia thereon related to the computer program and which is removable via at least one perforated line leaving at least another portion of that flap panel disposed over the diskette to hold it in place.

Abstract: The invention relates to apparatus for the storage of visible index records and the like, assembled in panels, trays, and the like. The panels are stored side-by-side, suspended vertically below a plurality of horizontal panel-carriers which are arranged side-by-side and are independently pivotable at their mid-points about a common horizontal axis. Each panel is attached to its panel-carrier for swinging movement in a direction at right angles to said common axis so that by pivotting a panel-carrier through 180.degree. to an inverted position the panel or panels attached thereto may be swung to a substantially horizontal position to provide access to the records or the like.

Abstract: The invention relates to a visible index, and to a novel carrier for the records of a visible index, in which the records are hooked over retaining flanges which extend inwardly of the V-shaped channel portions of carriers which also comprise spacer portion which extend above the apices of the channel portions and locate respectively in the channel portion of the carrier directly thereabove, to provide an overlapping array of the records hooked on the carriers and also further to inhibit detachment of a record hooked on a retaining flange, as well as optionally also further records attached to the carriers, by the internesting of adjacent carriers.
