Abstract: A slingshot device includes a missile and a launcher for launching the missile, the launcher including a handle adapted to be grasped by a user, an elastic strap for projecting the missile, the elastic strap having a first end connected with the handle and a second free end, a launching wedge affixed to the free end of the strap for releasably coupling the free end of the elastic strap with the missile such that upon drawing the free end back away from the handle and then releasing the free end the missile is accelerated forward and launched beyond the handle, and a somewhat flexible control tube connected to the handle for restraining any uncontrolled whipping about of the elastic strap and essentially precluding travel of the free end of the elastic strap forward beyond the handle, the control tube essentially surrounding at least a portion of the length of the elastic strap so that the elastic strap is retracted within the control tube upon launching of the projectile and is precluded from following the pr

Abstract: A modular humeral shoulder prosthesis for implant in a predetermined position in the natural humerus to replace the natural humeral head of a shoulder joint with a prosthetic implant has a humeral head component including a humeral head member with a spherical bearing surface of predetermined radius extending from an origin to the bearing surface, an undersurface extending in a first direction, an elongate post integral with and projecting in a given direction from the humeral head member, the given direction making a first acute angle with the first direction, and a post portion on the post, and a humeral stem component including a platform having an upper surface, a stem integral with and depending from the platform, the stem extending along a longitudinal axis for alignment generally longitudinally along the natural humerus, the upper surface extending in a second direction making a second acute angle with the longitudinal axis, and an elongate recess in the stem, the recess extending along the stem and in

Abstract: Method for selectively rotationally molding an industrial drum in either a closed-head configuration or an open-head configuration within a mold constructed for selective modification to accomplish molding of the drum in either selected configuration by inserting or deleting a separator between a first mold cavity for forming the body of the drum and a further mold cavity for forming the head of the drum, the further mold cavity being selected from alternate second and third mold cavities, such that both the body and the head are rotationally molded simultaneously within the mold during molding of either configuration of the industrial drum.

Abstract: An article of manufacture, such as a wiper, especially suited for use in a controlled environment, such as a cleanroom environment, and a method for controlling the entry of deleterious particles into the controlled environment, within which environment a process is carried out, the article being constructed of fibers of a synthetic polymeric material of the type including only constituents which are relatively benign in that the included constituents will be less likely to have a deleterious effect upon the process carried out in the controlled environment or upon the product of that process, the method including constructing the article of such fibers, the preferred synthetic polymeric materials including no more than only negligible amounts of inorganic constituents or metallic constituents, one such preferred synthetic polymeric material being nylon bright.

Abstract: An improvement in a rheometer and the method for measuring rheological properties of a viscoelastic test specimen at different temperatures, at which different temperatures the viscoelastic properties exhibit a relatively wide difference, wherein the test specimen is placed between and is coupled with opposed plates, one of the opposed plates is oscillated angularly relative the other of the opposed plates, and the angular displacement of one of the plates relative to the other of the plates and the torque associated with the relative angular displacement are measured within a predetermined optimum range of torque and angular displacement for determining the rheological properties, couples a first contact surface on one of the opposed plates with the test specimen to establish a first contact area between the one of the opposed plates and the test specimen when the test specimen is at one of the different temperatures, and couples a second contact surface on the one of the opposed plates with the test specime
