Title: Portable retractable extension cord
Inventor: FONSEKA DAVID M
IPC: H02G11/02
Filed: 1992-12-31
Abstract: ABSTRACT OF DISCLOSURE     The apparatus is a Portable Retractable Extension Cord in which a cord is wound over a spring-loaded reel in a plastic encasing. A male attachment plug is affixed to the side of the encasing with its wires connected to three separate metal plates on a cam inside the encasing. The female attachment plug is connected to a 15 metre 3-wire single-phase cord wound over the reel inside the encasing and its wires riveted to three slip rings at its side. When used outdoors,the apparatus is mounted on a stake which allows it to rotate 360 degrees on its axis. The torsional spring-loaded reel retracts the cord into the encasing when it is pulled,  eliminating slack but retaining electrical contact between the slip rings and the plates whether or not the reel is rotating.The main application of the apparatus is for use with electrical lawnmowers as existing outdoor extension cords must be manually wound or placed aside out of the way of the lawnmower's blades and the few retractable cords available in the market are limited for indoor use at workshops or come as part and parcel of vacuum cleaners. This apparatus can be used both indoors and outdoors with a variety of electrical devices.
Patent CA-2087748-A1 (CA)
IPC: E03D3/10
Filed: 1993-01-21
Abstract: A coupling connects a pressurized flush water vessel held in a toilet tank to a toilet bowl.  The coupling has a passageway which provides direct fluid communication between the vessel and the bowl and a chamber for accumulating drainage, which may be exhausted into the toilet tank from inlet devices for the pressure vessel.  A swinging door type one way valve substantially seals against leakage from the passageway to the chamber but allows drainage accumulated in the chamber to flow through a port to the passageway.  The inlet to the chamber is above the port and at or below the bottom of the toilet tank and the port and the chamber inlet open above the spill level of the toilet.  The inlet of the coupling is offset from the outlet and a cradle elevates the pressure vessel above the toilet tank bottom and captures heads of fasteners which secure the toilet tank to the toilet bowl.

Title: Arc discharge lamp with spring-mounted arc tube and shroud
Inventor: HUNTER SCOTT R
IPC: H01J61/04
Filed: 1991-11-25
Abstract: A metal halide arc discharge lamp includes an arc tube (14) and a light transmissive shroud (16) mounted within a lamp envelope (12). The arc tube (14) and the shroud (16) are mechanically supported within the lamp envelope by resilient spring members (102, 104, 106, 108). Since the support structure for the arc tube (14) and the shroud (16) is mechanically and electrically isolated from the lamp stem, leakage current between the support structure and the electrical inleads is eliminated, thereby reducing sodium loss from the arc tube (14) and extending the operating life of the lamp. The spring-mounted construction enables the lamp to withstand mechanical shock and vibration.
