Abstract: A novel wire twister apparatus and method provide a reliable, one hand powered tool having no moving parts to make uniform and tight electrical conductor connections ready for insulating nuts or caps. The novel wire twister is used by either professional or novice on 2-6 solid 10-14 gauge wires in either standard and awkward work positions. A hand-powered wire twister and method of the present invention include means and method for providing a handle, a wire twisting member connected to the handle, and a plurality of wire receiving apertures in one end of the wire twisting member having a fixed number of interchangeable wire receiving apertures.

Abstract: A method for providing hydrophilic contact lenses with identifying means incorporated into lens blanks and the resulting lenses in which an elongated identifying strand, fiber, or rod is molded into a cylindrical lens blank rod positioned substantially parallel to the axis of the rod. Lens blanks or buttons are cut transversely to the axis and the lens blanks ground to the proper optical curvatures. The contact lens blanks each contain portions of the identifying means. The finished contact lenses each contain short segments of the identifying means thereby allowing classification of the contact lenses as to right or left eye, magnification power or other characteristic.

Abstract: A new concept in polymeric prosthetic devices having a portion thereof composed of a hydrophilic polymer is described herein in which distortions and stresses upon the device due to water absorption are minimized or eliminated. Physical properties of the various portions of the device may thus be varied to provide the particular physical parameters required. Compositions of matter and methods of manufacturing the novel prosthetic devices are described. The composition of matter is a polymer which includes a water soluble solid inert substance removable by exposure to water during hydration of the hydrophilic portion of the device, thus eliminating distortions and stresses therein. The hydrophilic polymer described is useful, for example, as one component part of such prosthetic devices as a hard-soft contact lens, cardiovascular implants, etc. useful in aqueous environment wherein stress and deformation of the polymer shape due to hydration must be minimized.
