Abstract: A method of recutting the surface of a wheel includes mounting the wheel on a rotatable mount, moving a probe across the surface of the wheel between an outer radial position and an inner radial position to obtain a radial surface profile and rotating the wheel about its axis on the rotatable mount. During rotation of the wheel, the position of a cutting tool with respect to the surface of the wheel is controlled to recut the surface of the wheel in accordance with the cutting profile. The wheel is tagged with a unique wheel identifier, and the unique wheel identifier is recorded into a database in association with an indication of an amount of material which has been removed from the surface of the wheel.

Abstract: A device for covering the eyes comprises a face-covering element, formed by a first layer of transparent elastic material, which, in use, is stretched to sealingly cover the wearer's eyes, and arms which, in use, extend around the wearer's head to hold the device in place. The device is particularly suitable for use as a swimming mask.

Abstract: A tool for fastening fencing material to a post with a staple. The tool includes a base plate; first and second handles; first and second crimping arms, and a cam operatively engaged with the first handle. A slide is operatively engaged with the cam. The first and second handles and the first and second crimping arms are pivotally interconnected and attached to the base plate so that when the first and second handles are pivoted towards one another from an open position, the cam advances the slide, which advances the staple so that the crimping arms may crimp the staple to the fence post. A method for attaching the staple to a fence post is also described and claimed. An inventive staple is also disclosed.

Abstract: Disclosed are crystalline polyesters having low melt viscosities, and thermosetting compositions comprising these polyesters. The compositions are especially useful as powder coatings. At least 40 mole percent of the acid moiety is a terephthalic or isophthalic acid moiety, and the polyester contains as moieties of the dihydric alcohol about 40-100 mole percent 1,6-hexanediol, the polyester being further characterized as having a molecular weight of about 700-3000, a melt viscosity of about 50-3000 cps at 160.degree. C. and a hydroxyl number of about 30-160.

Abstract: Disclosed ar novel polyamine compounds having the general formula ##STR1## wherein R, R.sup.1, R.sup.2 and R.sup.3 are each independently selected from hydrogen and alkyl groups which may be substituted, the preparation of such compounds and their use as curing agents for epoxy resins.
