Title: Football game system and method of play
Inventor: FOSTER JAMES F
IPC: A63B69/00
Filed: 1988-09-30
Granted: 1993-03-02
Abstract: ABSTRACT              A new game is disclosed, involving substantially the same rules as American football (e.g., NFL or NCAA) except that kicks or passes into the end zone may be deflected back onto the playing field as a playable ball by a rebounding assembly that surrounds the goalposts.  Upon an attempted field goal, an errant kick will result in the ball hitting the rebounding assembly instead of passing between the vertical uprights of the goalposts.  The reflected ball can be caught before it hits the ground by only players of the team defending the goal.  Once caught, the defending team may advance the ball toward the opposite goal in accordance with the normal rules of American football.  If the ball reflected off of the rebounding assembly hits the ground before it is caught by a player of the team defending the goal, the ball is free for players of either team to advance.  In order to ensure that an errant kick results in the rebounding of the ball back into the playing field, the rebounding assembly is comprised of resilient material that returns much of the kinetic energy to the ball after it impacts the rebounding assembly.  The rebound assembly for playing the game is comprised of a goalpost substantially similar to that used in American football, with the exception that the instant goal is provided with a goal rebound net extending outward from each side of the goalpost, along the extremity of the end zone to substantially the entire width of the playing field.

Title: Alignment of lithographic system
Inventor: WHITE DONALD L
IPC: H01L21/027
Filed: 1989-04-26
Granted: 1993-08-17
Abstract: Abstract A method for lithographic alignment utilized in the manufacture of integrated circuits is described. The procedure includes an initial calibration through the lens system to expose a calibration material in a diffraction grating pattern. An interference pattern is produced above the grating with intersectinglaser beams. By adjusting the path and/or phase of these beams the interference pattern is aligned with the diffraction pattern to establish a calibration pointcorresponding to a reference intensity in the intensity of the diffracted light. A wafer to be exposed is then placed in the exposure tool and is aligned by observing the diffraction pattern from a diffraction grating fiducial mark induced by the calibrated interference pattern.

Granted: 1994-01-04
Abstract: ABSTRACT OF THE DISCLOSURE The  method  according  to  the  invention makes  it  possible  rapidly  to accelerate a test piece in a start-up phase in accordance with a stipulated acceleration program, and subsequently to maintain the test piece at constant acceleration during an arbitrary time.  The testing device for carrying out the method consists  of a rotor carrying the  test piece.   The  rotor is accelerated by a pressure medium in its start-up phase and is driven in its stationary phase by an electromotor via a toothed belt.   In the start-up phase, the test piece experiences a continuous rotation from the tangential direction of the circular path (K) into the radial direction by the angle of rotation ? of 90°. A preferred use of the device resides in testing rocket nose cones.  This replaces real launching and/or expensive linear accelerators.

Abstract: TITLE: PANEL FASTENER CLIP AND METHOD OF PANEL ASSEMBLY  Abstract of the Invention Construction methods and clip apparatus for joining or repairing wall  or ceiling panels such as sheet rock,  gypsum boards, plywood, or other generally planar wall panels. The clip is enables permanent edgewise joining of wallboard panels, ceiling panels, or the like at any desired position along the length of the wall  frame or ceiling framework independent of framing back- up studs or joists.  A plurality of metallic clips unite to provide an edgewise mechanical bond between adjacent panel edges by creating an artificial backing in wall regions having no studs or support columns.  A preferred clip comprises a generally planar,  elongated body having a pair of parallel reinforcement grooves, and the body is preferably stamped from metal stock and selectively perforated.   A pair of integral, spaced apart, prong-like spring tab structures formed on opposite sides of the clip body initially grasp the edges of a panel. Each spring tab includes an integral, upwardly extending vertical portion disposed substantially perpendicularly to the body and an integral, arcuate, substantially horizontal flange portion.  The flange portion is separated from its vertical companion by a weakened, scored tear edge which permits manual removal of the flange by appropriate bending after clip installation.   the spring tabs project toward the clip front to maximize the working area of the clip body available for fastening to the second or later panels.   A pair of opposing riser wings extend upwardly from either side of the front body portion.  When installed, the wallboard panel is contacted by the riser wings and retained at an angular disposition relative to the next adjacent panel, to insure a smooth, gap-free seam.

Abstract: STRUCTURE FOR ENHANCED RETENTION OF ARTIFICIAL LIMBS AND METHOD OF FABRICATION            ABSTRACT OF THE DISCLOSURE        An air impermeable sealing band of rubberized material is introduced between the patient's stump and the interior of a stump-receiving socket of an artificial limb,  in one of two ways, depending on whether or not the patient wears a stump sock.  If the patient wears a stump sock, the band of sealant material is impregnated into the stump sock.   If the patient does not wear a stump sock, an impregnated sock is incorpora-ted into the interior structure of the socket of the patient's prosthesis.   The impregnated sock itself  is  fabricated by placing a conventional stump sock on a somewhat oversized form. An appropriate annular region on the sock is then masked off by means of tightly fitting plastic bags, and one of the plastic bags provides an enclosing outer sheath which encompasses the annular region and extends upwardly above the form.  A rubber-ized material in liquid form is introduced through the top of the outer sheath and a vacuum is introduced below to draw the material into the annular region of the sock, so as to impreg-nate the same.  The rubberized material penetrates the sock, is worked into an axially contoured shaped, and is then permitted to set.  A stump-receiving socket for an artificial limb with an integral annular seal is fabricated by placing a stump sock with the seal on a cast of a patient's leg and then laminating the socket over the sock using conventional procedures  for manufacturing stump-receiving sockets.

Title: Molded polymers with hydrophilic surfaces, and process for making them
Inventor: MUELLER KARL F
IPC: B29C41/00
Filed: 1989-09-25
Granted: 1993-11-02
Abstract: MOLDED POLYMERS WITH HYDROPHILIC SURFACES, AND PROCESS FOR MAKING THEM Polymer composites are described which consist of a 0.1-500micron thick film of a preshaped, surface-forming hydrophilic first polymer A covalently grafted onto an underlaying bulk and structural second polymer B and which are prepared by polymerizing said second polymer B on a substrate which is coated with the hydrophilic first polymer A, said first polymer being able to co-react with the monomers used to prepare the second polymer B. Because of their continuous nature and covalent bonding, the hydrophilic surface films of polymer A adhere tightly to the underlaying polymer B and also conform exactly to the configuration of the substrate or mold; polymers with such permanently modified surfaces are useful as biocompatible materials, for instance as contact lenses or as low-friction or non-blocking elastomers, as well as non-fogging, washable and printable polymers. The instant process can also be adopted to prepare the reverse type of polymer composite comprising a hydrophilic polymer with a thin hydrophobic or lipophobic surface. Such composites can be used as membranes, release-rate controlling devices and solvent and soil-resistant polymers.
