Abstract: Member of polymethylmethacrylate, polysulfone, polymer or a like material with a plurality of holes arranged in a predetermined, geometrical configuration. The holes are derived at through a procedure of repetitive drawing. Prior to the first drawing operation, each of the holes is filled with a material which is soluble to a certain chemical, yet drawable along with the base material. The member of material can be square, drawn to a reduced cross-sectional area as a square, the reduced cross-sectional members positioned with respect to each other and drawn again in a further operation, and repeated accordingly so that the cross-sectional area of each hole is reduced in proportion to each drawing step. Dependent upon the final drawing step, a subsequent member is provided which includes holes of a significantly reduced cross-sectional area. The member can be utilized as either a contact lens, an intracorneal inlay, an intraocular lens, a medical filter, or a like structure with small holes.

Abstract: A guide wire having state-of-the-art handling characteristics for ease in positioning a variety of catheters and other devices within the cardiovascular or other body system wherein the guide wire is also suitable for infusion of small volumes of fluid. The exceedingly small diameter guide wire has unique infusion properties. The guide wire body has at least one helical coil having a flexible nonporous sheath within the lumen. The helical coil is close wound along the majority of its length. The distal end of the helical coil has spaced windings to permit infusion of the fluid. The flexible nonporous sheath terminates proximal to the space wound portion. The solid core wire, which runs the entire length of the guide wire, is located within the same lumen used for infusion. This provides a greatly increased surface area in relation to the cross sectional area of the infusion lumen ensuring a slow but extremely constant infusion rate over a wide range of infusion pressures.

The interior of the housing is divided so that approximately one-half to three-fourths of the interior space or volume is accessible by the input and output doors in the front panel and the remaining interior space is accessible from an input door in the first end panel.

Abstract: A substantially one-piece ladder attachment is disclosed. The attachment provides a secure, laterally well-supported platform on which a worker wound stand. The invention is particularly useful for an extension ladder, especially one with circular rungs. The attachment of the invention comprises a platform having a single, preferably hollow, vertical support member projecting adjacent one edge thereof. The vertical support is centrally disposed on the edge on which it is located. The vertical support angularly projects from the platform and is connected to an arcuate, horizontally disposed, transversely mounted upon bracket. The upper bracket is intended to engage the rung of a ladder to impart lateral stability to the platform. The attachment further includes a lower, horizontally-disposed, arcuate bracket which is located on the same edge of the platform as the vertical support.

Abstract: A plug-type artificial fishing lure contains a mechamism within the body which operates as a leader dispensing and retrieving means. The mechanism is disposed in a cavity of the body, and includes a rotatable axle with a spool mounted thereon. The axle includes a ratchet means, and a trigger means releasably engages the ratchet thereby controlling rotation of the axle. The leader is dispensed by unwinding from the spool, and retrieved by rotating the axle and spool by a wind-up means, such as a spring, in a direction opposite the dispensing direction.

Abstract: A board game apparatus and method are disclosed. The board game and method have a transportation motif, a railroad motif being preferred. In its preferred practice, play of the game involves completion of a plurality of shipments or deliveries of commodities to a plurality of destinations. A novel method of playing the board game is disclosed which involves placement of described means to avoid various strategically determined consequences.

Abstract: A substantially one-piece ladder attachment is disclosed. The attachment provides a secure, laterally well-supported platform on which a worker would stand. The invention is particularly useful for an extension ladder, especially one with circular rungs. The attachment of the invention comprises a platform having a single, hollow, vertical support member projecting from one edge thereof. The vertical support is centrally disposed on the edge on which it is located. The vertical support angularly projects from the platform and is connected to an arcuate, horizontally disposed, transversely mounted upper bracket. The upper bracket is intended to engage the rung of a ladder to impart lateral stability to the platform. The attachment further includes a lower, horizontally-disposed arcuate bracket which is securely mounted to the same edge of the platform as the vertical support.

Abstract: Highly stable, segmented, aliphatic polyurethanes prepared by particular processes are disclosed. The segmented polyurethanes of this invention are substantially free of ester and ether linkages and are found to be particularly hydrolytically and oxidatively stable. The polyurethanes of this invention are prepared by a particular two stage process involving the formation of a prepolymer and subsequent reaction with simultaneously or sequentially added diisocyanate and diol monomers.

Abstract: A visual (as opposed to mechanical or electronic) method for detecting the state of dehydration (or hydration) of a biomedical hydrogel is disclosed. The method contemplates incorporating a pH sensitive indicator into the hydrogel as it is prepared and applying the hydrogel to the skin-contacting surface of a biomedical device such as an electrode. Shortly before the biomedical device is to be used, the color of the hydrogel on the device is visually compared with its freshly-prepared color to determine the approximate state of dehydration of the gel.

Abstract: A small plastic connector is provided with a unique electrical contact mounted in one jaw of the connector to mate with an angled edge on the other jaw of the connector to crimp and securely grip a thin, flat, flexible electrode in the connector while making good electrical contact. The jaws and the contact are further constructed so that the conductive surface on the electrode is pressed into engaging with a large contact surface.
