Abstract: In a process for producing a profile by profile extrusion, a melt of a polyester composition is extruded through a die to form a profile. The processability of the polyester composition is improved by the addition of a branching agent, which provides increased melt strength and increased high shear thinning. The polyester composition has an inherent viscosity of at least 0.65 dl/g. The diacid component of the polyester composition has from 100 to 98.0 mole percent of residues of a primary acid selected from terephthalic acid, naphthalenedicarboxylic acid, isophthalic acid and mixtures thereof. The glycol component of the polyester composition has from 100 to 98.0 mole percent of residues of a primary glycol selected from ethylene glycol, 1,4-cyclohexanedimethanol, diethylene glycol, neopentyl glycol, and mixtures thereof. The polyester composition has from 0.05 to 2.

Abstract: This invention encompasses novel methods of preparing sulfinamides and sulfoxides, particularly stereomerically pure sulfinamides and sulfoxides. The invention further encompasses novel compounds from which sulfinamides and sulfoxides can be prepared.

Abstract: A muntin bar clip includes a contoured body that is shaped to contact the interior of top, bottom and opposing side walls of the muntin bar, and a head that is rotatably attached to the body. The end of the body to which the head is attached is narrowed, to accommodate the rotation of the head without drawing the body from the muntin bar. The body includes projections that extend upwardly and downwardly, and contact the top and bottom walls of the muntin bar. The head includes an L-shaped end, with an upwardly extending wall and a bottom wall. A downwardly extending extension connects to the bottom wall opposite the upwardly extending wall. The extension, which rotatably connects to the body, is separated from the upwardly extending wall by the width of the bottom wall, which is approximately one-half the width of a spacer. The upwardly extending wall is held between the spacer and a sheet of glass.

Abstract: An interactive display device is of the type which displays data and allows an operator to input fresh data and/or change the data that is displayed. The data is displayed by a plurality of arrays of discrete display elements each of which can be independently driven to produce an optical output, and the interactive input is by means of a light pen or "wand" which detects light and which the operator points at the display element associated with the data to which the desired input relates. Driver circuit means scan the arrays of said plurality thereof simultaneously with signals which determine whether each display element is in the ON or OFF state. These scanning signals include coded pulses the coding of which is representative of the particular array being scanned thereby. Means for inputting data comprise said light pen and associated circuit means operative to identify the coded pulses and thus identify the array containing the selected display element.

Abstract: An improved, low cost, net-mounted tennis target structure is provided for improving tennis skills which permits practice on an otherwise unmodified regulation tennis court and allows the player to actually see the landing of his shot beyond the net which ensures that actual court conditions and "feel" are not lost during practice; in addition, the structure is adjustable for individual players and permits practice on specialized serves and ground strokes while ensuring that all such shots land within the appropriate court playing area beyond the net. While a single player can utilize the target structure to good effect as a practice aid, an opposing player can also simultaneously use the structure to give both players the benefit of return strokes so volleys of shots can be exchanged to accurately simulate actual conditions of competitive play.
