Title: Electrolyzer and method of operating same
Inventor: ISHIBASHI TADAYA
IPC: C25B9/19
Filed: 1991-12-24
Abstract: ABSTRACT       The present invention relates to an electrolyzer for treating an object liquid.  A cylindrical anode plate is formed as an outer wall of said electrolyzer and a cylindrical cathode plate is coaxially arranged at a position close to an inner surface of said anode plate.  An ion exchange membrane is coaxially arranged between both electrodes to form an isolating chamber for a selective electrophoretic separation and removal and a concentration.  A liquid, which has been subjected to an aimed treatment in said isolating chamber, is uniformly flown out from a whole circumference through a circumferential passage provided in an upper portion of an electrode portion.  Thus, anions, which have acted upon metal cations, are dissociated in said isolating chamber to selectively separate merely cations.  In addition, an improvement of the anode brought into contact with said object liquid in durability, a simplification of electrode surfaces in repair and processing, a uniformation of a current density, a handling of the liquid under the conditions corresponding to an operating object of the electrolyzer and the like can be achieved.

Title: Golf putting aid
Inventor: KANELOUS K JOHN
IPC: A63B57/00
Filed: 1992-07-30
Abstract: Inventor: Kanelous Title: Golf Putting Aid ABSTRACT      Most golf greens slope, which causes balls that are putted on them to follow curves, rather than moving in straight lines.  An heuristic  visual  device  is  provided  to  assist  a  golfer  in estimating how a putted golf ball will "break" on a sloping green. The invention provides graphic representations of trajectories of putted golf  balls  rolling on  greens  that  slope solely along principal directions (i.e. front-to-back and right-to-left).   A golfer, who must initially estimate how the green on which he is planning to putt actually slopes in the two principal directions, can  mentally  combine  those  graphically  represented  putting trajectories  in order to estimate the effects of gravity and thereby to predict his proper 'line of play'.   In a preferred embodiment, a transparent substrate, which has putting trajectories from a green that slopes solely from front to back printed on its top surface and putting trajectories from a green the slopes solely from left to right printed on its bottom surface,  is used to facilitate the golfer's mental process of  superimposing those trajectories to arrive at a net estimated trajectory.

Abstract: A tamper-sensing system for an electronic tag 10 which is to be fixed to a surface 11 of an article 12, the tamper-sensing system comprising a capacitor having two non-contacting, capacitively-coupled elements 16, 19.      Fixing of the body to the article will establish a precise location of the capacitor elements 16 and 19 relative to each other. When interrogated, the tag will generate a tamper-sensing signal having a value which is a function of the amount of capacity of the capacitor elements. The precise relative location of the capacitor elements cannot be duplicated if the tag is removed and affixed to a surrogate article having a fiducial capacitor element 19 fixed thereto. A very small displacement, in the order of 2-10 microns, of the capacitor elements relative to each other if the tag body is removed and fixed to a surrogate article will result in the tamper-sensing signal having a different, and detectable, value when the tag is interrogated.
