Patent CA-2552015-A1 (CA)
Inventor: HALL JONATHAN E
IPC: G06F1/16
Filed: 2004-12-29
Abstract: A system and method for an improved multiple-hard-disk-drive data-storage enclosure (1400). Some embodiments position drives in counter-rotating pairs, each simultaneously accessing half the data, such that seek-caused actuator rotational-acceleration vibration cause simultaneous canceling rotational torque. Some embodiments position the edge of a first drive (or drive pair) (1120) at an angle to the actuator midpoint of a nearby second drive (or drive pair) (120), such that rotational-acceleration vibration from a seek-caused actuator rotation in the first drive does not cause a rotational movement into the second drive that affects the tracking or seek operation. Some further embodiments position drives (120, 1120) in a herringbone pattern to redirect air flow in addition to reducing rotational-acceleration vibration interaction. Other embodiments include a printed wire circuit board mounted to reduce the rotational-acceleration vibration interaction.

Title: Manipulable puzzle cube
Inventor: SUGDEN MARTIN JAMES
IPC: A63F9/08
Filed: 2005-02-17
Abstract: A manipulable puzzle cube is an improvement of the classic Rubik's Cube. The puzzle cube consists of a plurality of cubic elements connected to a centrally positioned interior connecting element, the cubic elements of each surface of the cube forming a plate of cubic elements, the plate being rotatable about a spatial axis of the cube, each of the cubic elements having one or more exposed faces. All of the exposed faces of a given cubic element are the same colour, the colour being selected from a group of colours comprising at least two colours. The colour of each cubic element is selected so that the cubic elements form a decorative pattern on each surface of the cube. The pattern may be the same on each surface of the cube, and may take the form of a "Y" or no "tic-tac-toe" pattern. The subject puzzle cube is more appealing to the eye than the classic Rubik's Cube, and its manufacture is simplified.

Patent CA-2590359-A1 (CA)
Inventor: ABELEIN DWAYNE M
IPC: E03C1/296
Filed: 2007-05-29
Abstract: A pressure activated trap primer valve for drain traps includes an expansion chamber with a piston between the compressible air and water. The piston prevents waterlogging of the expansion chamber to reduce maintenance of the trap primer valve.  The trap primer valve also includes an inlet pipe coaxially configured in the expansion chamber. The inlet pipe is operably connected to a chamber below the expansion chamber which is closed at the bottom by a diaphragm. The diaphragm in a relaxed, undeflected position closes an outlet that drains to the trap. A chamber below the diaphragm is replenished by the expansion chamber. When pressure in the supply pipe and inlet pipe decreases, such as when a faucet is opened, the diaphragm deflects.  Deflecting the diaphragm opens the outlet, allowing a limited amount of water to flow out of the chamber and into the trap. The intermittent water flow to the trap ensures a minimum volume for maintaining a gas tight seal in the trap. As trap primer valve pressures reach equilibrium, the diaphragm returns to an undeflected position, sealing the outlet again.
