Title: Automatic grounding clip
Inventor: MOREAU BERNARD
IPC: H01R4/64
Filed: 1988-02-24
Granted: 1991-06-18
Abstract: Abstract Of The Disclosure An automatic grounding means for a wiring device is provided by a spring clip formed from a single piece of wire in a generally U-shaped configuration, bent upwardly at both ends.  The bent end portions are inserted through a pair of openings on opposite sides of the conventional mounting screw slot in the ears on the yoke of the wiring device, and are further bent either toward or away from one another to maintain the clip in firm engagement with the yoke without welding or other such permanent connection.  When mounted on the yoke, parallel legs of the clip extend across the screw slot and are spaced by a distance less than the diameter of the mounting screw which thereby contacts the legs, flexing them outwardly, as the mounting screw is passed through the slot and between the clip legs to engage the flush box in which the wiring device is mounted.  The engagement Or the clip with the yoke assures a low resistance grounding path from the yoke to the clip to the screw to the flush box.  The clip is disclosed in two embodiments respectively suited for automatic and manual assembly of the clip with the yoke.

Inventor: DEMIRYONT HULYA
IPC: G02F1/1524
Filed: 1988-10-28
Granted: 1992-02-11
Abstract: Abstract of the Disclosure This invention teaches an electrochromic device in which an electrochromic layer is positioned between two electrodes.  The electrochromic layer comprises an inorganic based bulk material supporting electrochromic particles and ion producing particles in fixed but generally distributed positions therewithin.  The bulk material permits migration of ions produced by the ion producing particles to and from the electrochromic particles upon change in voltage between the first and second electrodes.  The bulk material also prohibits the passage of electrons therethrough when a voltage is applied between the first electrode and the second electrode, whereby an electric field is built up between the first and second electrodes which causes migration of the ions.  A preferred method of making a material which can form an electrochromic layer is also disclosed.

Abstract: BIOELECTROCHEMICAL REACTIONS IN ORGANIC SOLVENTS   ABSTRACT   A method of determining an analyte in an organic or microaqueous solution involves the use of an enzyme electrode at  which  an  enzyme  is  retained.   The  enzyme  may  be immobilised covalently at  the electrode but is preferably retained at a hydrophilic support (4) which may be connected to an electrical  conductor.   Electrochemical detection of analytes in organic or microaqueous solvents using an enzyme electrode has several advantages over existing methods which employ aqueous solutions of analyte.   For example compounds with low water solubilities may be detected, detection of a particular analyte may be made more selective by appropriate choice of solvent, the thermal stability of the enzyme may be enhanced and  the enzymes may be  readily retained at  the electrode by virtue of their insolubility in the organic or microaqueous solvent.
