Abstract: An improved golf swing training device that includes a curved platform with right and left adjustable strike plates, each having adjustable swing plane guide rods connected by a rotating disk attached to the rear of each strike plate. The curved platform, duplicating the bottom path of the proper curved golf swing, is attached to a single straight track by means of multiple horizontal bearings. The curved platform moves fore and aft along the straight track. The bearings provide both retention and backstroke/reverse and follow-through/forward movement of the curved swing platform. The elongated and angled strike plates with the extended guide rods guide the club through backswing and follow-through. Adjustable resistance can be added to the curved platform to assist strength training.

Abstract: A device that helps a golfer improve their swing by providing a track over which to swing the club, a strike plate which swivels to keep contact with the club as long as possible and a resistance to movement over the strike plate in the track so the player understands the weight transfer required in a golf swing. An embodiment includes a sled sliding on at least one rail with front and rear strike plates and a center resistance mechanism that provides adjustable resistance to the swing using pads to contact the rails. The user can set different ranges of resistance.

Abstract: An interactive help system allows a user to retrieve information concerning how to complete a particular task in an underlying computer program. Upon selecting the help system, the computer system re-sizes the window of the underlying program and generates a help window containing a list of topics that are available. A help window is created beside the underlying program window that lists those steps required to complete a desired task. The help system disables that portion of the underlying program window containing options that are inappropriate for the user to select at that time in order to complete the desired task. In addition, the help system shows the user how to complete the next step in the list of desired steps. Alternatively, the user can have the help system show the user how to perform all the steps required to complete a given task.

Abstract: An acrylic fiber useful in the preparation of precursor fibers for the preparation of carbon or graphite fibers contains 93.0-99.4 mol percent acrylonitrile, 0.6-4.0 mol percent of ammonium or amine having a pKb of 5 or less as neutralizing cations for sulfonic and sulfuric acid end groups derived from the initiator and activator and as neutralizing cations for sulfonic acid groups derived from one or more sulfonic acid containing comonomers and 0-3.0 mol percent of one or more comonomers selected from the group consisting of simple acrylate or methacrylate esters, simply vinyl esters, styrene, vinyl chloride and vinylidene chloride, the fiber containing no more than 0.3 mol percent of cations other than ammonium or amine.

Abstract: Tows of highly entangled, continuous, eccentric bicomponent acrylic filaments in which the filaments have a density of about 1.0-1.17, an equilibrium crimp reversibility (ECR) of at least about 20% and a filament entanglement value greater than about 12 and less than about 60 are provided by drying previously undried tows of continuous acrylic filaments having an eccentric bicomponent structure in which a large difference exists between the hot water swellability of the components of the filaments, as indicated by their ECR, to a maximum moisture content of about 3% by weight of the filaments at a temperature below the hot-wet glass transition temperature of the fiber polymers.

Abstract: Slub yarns are prepared by adding 10-50% by weight 0.25 to 1 in. long bicomponent acrylic fibers having a density of about 1.0 to 1.17 g/cm.sup.3 and an equilibrium crimp reversibility of at least about 20% with staple fibers during or before carding and processing to a slub containing spun yarn in a conventional manner.
