Patent CA-2254965-A1 (CA)
Title: Oil filter crusher
Inventor: GROSS JOHN G
IPC: B30B9/32
Filed: 1997-05-30
Abstract: An oil filter crusher includes an elongated triangular frame, a threaded drive screw (10), and a ram assembly, but does not include any actuator for driving the screw. Rather, a first end of the drive screw has a drive head (12) to which a user may couple a conventional wrench, such as a pneumatic impact wrench of the type commonly used in automotive service centers. A thrust bearing assembly (40) couples the second end of the drive screw to the ram assembly (32). A threaded portion of the drive screw (10) engages a threaded opening in a portion of the frame. The ram assembly (32) thus moves in an axial direction in response to rotation of the drive screw with respect to the frame. Rotating the drive screw in one direction moves it toward the filter to be crushed, and rotating it in the opposite direction moves it away from the filter.

Patent CA-2258468-A1 (CA)
Inventor: CINKANT ANTHONY
IPC: E03C1/28
Filed: 1999-02-05
Abstract: In a domestic drain system in a house or other building, there exists a number of fittings called P-Traps. There is one at each fixture (i.e. sink, tub, etc.) A P-Trap's purpose is to hold back a small portion of water to block the drain system at the fixture. This blockage stops sewer gases and odours from returning back through the fixture into the house or building. In order for the P-Trap to function properly, it requires a vent to be connected to the drain system about 12 inches downstream from the P-Trap. The air vent serves to equalize the atmospheric pressure changes that occur within the system when water is flowing through it (i.e. emptying a sink). Without the air vent, the small portion of water (the trap is supposed to retain) is drawn out by a siphoning effect caused by the velocity of the flowing water when, for example, emptying a sink. This allows sewer gases to return through the dry trap and out through the sink. As an alternative to the P-Trap this invention directs the water flow (caused by the emptying of a fixture, i.e. a sink) into the bottom of a cylindrical chamber where under its own velocity is sent into a centrifugal motion as it passes through the chamber into the drain.          The centrifuge that takes place in the chamber has two advantages. 1. any particles heavier than water get forced to the outside of the centrifuge up against the vertical wall of the cylindrical chamber and cannot enter the drain. So if an article of value accidentally drops into the sink and enters the drain system it will not get past the trap and can easily be recovered. 2. As the sink empties and air begins to get sucked through the chamber momentummaintains the centrifugal action of the water in the chamber and gives the air (being lighter than water) a passage way up the centre of the chamber and out tothe drain until the siphoning effect subsides, this results in a greater amount of water being retained in the chamber for a better trap seal.
