Patent number: 5658648Abstract: Pressure-sensitive adhesive labels are disclosed, as might be particularly useful for application with electrical cord sets. The label is utilized to provide long-term, cautionary information regarding the dangers associated with electrical cord sets. The surface area of the label exceeds the circumference of the cord set, thereby allowing the label to wrap about the circumference of the cord set and adhere to itself, while also securely attaching to the cord set. The label comprises a primary adhesive which features a high shear adhesion property. A paper liner is removed from the primary adhesive prior to application to the cord set. The primary adhesive is provided on a bottom surface of a facestock, which has a high tensile strength and is preferably formed substantially from a vinyl material. Preferably, the facestock is provided with plasticizers and is topcoated. Printing ink displays a cautionary message on the topcoated upper surface of the facestock.Type: GrantFiled: August 23, 1995Date of Patent: August 19, 1997Assignee: Wisconsin Label CorporationInventors: Christopher Eugene Doerr, Daniel Richard Ray, Jodi Leigh Swoboda

Patent number: 5652679Abstract: An optical system including at least one lens and erecting mirrors designed and arranged to give an inherent aperture and field greater in one direction than another direction. By using a low power eyepiece lens it is possible to arrange for a user's eye or eyes to be further behind the eyepiece lens so that the user can wear normal spectacles to correct for eye defects. When a pair of the optical systems is used in a pair of binoculars, it is possible for the exit pupils to be in a form of horizontal slots so the systems do not have to have adjustable spacing to allow for a particular user's eye separation.Type: GrantFiled: March 26, 1993Date of Patent: July 29, 1997Assignee: Optics and Vision LimitedInventor: Michael Harold Freeman
