Title: Customized fit shoe and bladder and valve assembly therefor
Inventor: POTTER DANIEL R
IPC: A43B17/03
Filed: 1990-03-14
Granted: 1999-07-27
Abstract: A customized fit shoe, and particularly a high-top ice hockey skate, having a plurality of interior inflatable chambers. The chambers are configured and inflatable to different amounts to conform to the contours of the arch and the area below the malleoli of the foot in the shoe. The inflation of the chambers is accurately and easily adjusted through an upper push-to-deflate valve. When thereby adjusted, the concavities of the arch and ankle are filled without restricting the plantar or dorsi flexion of the foot.       An inflatable bladder and valve assembly for providing a customized fit for an athletic shoe is also disclosed herein. A shoe bladder having a plurality of compartments, which are air pressure adjustable through a bladder opening, is fitted into a shoe to individually fit the shoe to the foot. A finger tip actuable valve assembly is connected to the shoe bladder and communicates with the bladder opening. The valve assembly includes a valve housing, a valve seat disposed in the housing and having a conical-shaped seat area, a valve body and a biasing spring. The valve body has an inner portion having a flat surface and the biasing spring biases this inner portion against the valve seat such that the flat area mates against the conical-shaped seat area to hold the valve assembly in its normal closed position. The outer portion of the valve body can be depressed to open the valve and allow air to pass therethrough to inflate or deflate the bladder compartments as needed to provide a custom fit. It can be depressed by a finger tip or when a separable hand pump is attached thereto to open up the bladder opening so that air can be pumped into the compartments.

Title: Magnetic filter strap
Inventor: PERRITT RICHARD GARTH
IPC: B01D35/06
Filed: 1992-02-17
Granted: 1999-12-14
Abstract: A plurality of magnets contained or held within a flexible nonmagnetic strap which is wrapped around the exterior casing of a filter for liquids which are typically lubricating fluids. The magnetic fields created by the magnets attract and capture magnetic particles suspended within the lubricating fluid against the interior wall of the filter casing. The captured particles include particles too small to be captured by the filter itself but large enough to cause additional wear of parts if allowed to continue circulating within the fluid. The flexible strap containing the magnets may be wrapped around the filter any number of times thereby enabling the magnetic filter strap to fit numerous filter sizes. The flexible strap may also be made stretchable, with adjustable or non adjustable joining devices at the ends or may also have the ends permanently joined. This also enables the magnetic filter strap to fit filters of various sizes. The magnetic filter strap is reusable from filter to filter and can be used on spin-on or cartridge type oil filters used in automotive and industrial applications.

Title: Programmable graphics processor having pixel to character conversion hardware for use in a video game system or the like
Inventor: SAN JEREMY E
IPC: G06T17/00
Filed: 1992-07-22
Granted: 2003-01-14
Abstract: A fully programmable, graphics microprocessor is disclosed which is designed to be embodied in a removable external memory unit for connection with a host information processing system. In an exemplary embodiment, a video game system is described including a host video game system and a pluggable video game cartridge housing the graphics microprocessor. The game cartridge also includes a read-only program memory (ROM) and a random-access memory (RAM). The graphics coprocessor operates in conjunction with a three bus architecture embodied on the game cartridge. The graphics processor using this bus architecture may execute programs from either the program ROM, external RAM or its own internal cache RAM. The fully user programmable graphics coprocessor has an instruction set which is designed to efficiently implement arithmetic operations associated with 3-D graphics and, for example, includes special instructions executed by dedicated hardware for plotting individual pixels in the host video game system's character mapped display which, from the programmer's point of view, creates a "virtual" bit map by permitting the addressing of individual pixels -- even though the host system is character based. The graphics coprocessor interacts with the host coprocessor such that the graphics coprocessor's 16 general registers are accessible to the host processor at all times.

Abstract: An improved pipe jointing system includes sections of pipe having annular grooves about each of the ends thereof and a coupling having a rigid outer layer and an elastomeric inner layer fixedly secured thereto.  The inner layer has a inwardly directed lip and a pair of opposing sets of sawtooth ridges, one set disposed on each side of the lip.  A pair of the pipes inserted into opposing ends of one of the couplings in end-to-end relationship compresses the respective lip therebetween forming a fluid-tight seal between the coupling and the pipes.  The grooves are adapted to receive respective ones of the sawtooth ridges such that axial movement of the pipes relative to the coupling is resisted.   A modified embodiment provides a pipe and coupling system whereby an elastomeric inner layer of the coupling creates sufficient frictional force to resist axially outward movement of the pipes relative to the coupling.
