Patent CA-2514880-A1 (CA)
Inventor: CAMPOLO STEVEN
IPC: H02H3/33
Filed: 2004-02-02
Abstract: A resettable circuit interrupting device (Fig. 12) having a switch and timer circuit (SW3) connected to the line side of the interrupting device to cause a leakage current to flow for a defined interval when power is applied. If the device is not reverse wired, the timer continues to operate and the switch remains closed until the timer completes its cycle, at which time the switch opens and the neutral leg of the device is no longer connecterd to the ground terminal. If the device is reverse wired, the device will sense the reverse wired fault after the switch is closed, switches SW1 and SW2 will open, and line power will be disconnected.

Abstract: A framework defining a family of index structures useful in evaluating XML path expressions (i.e., twigs) in XML database is disclosed. Within this framework, two particular index structures with different space-time tradeoffs are presented that prove effective for the evaluation of twigs with value conditions. These index structures can be realized using access methods of an underlying relational database system. Experimental results show that the indices disclosed achieve significant improvement in performance for evaluating twig queries as compared with previously proposed XML path indices.

Title: Device for the variable actuation of the gas exchange valves of internal combustion engines
Inventor: KUHN PETER
IPC: F01L13/00
Filed: 2004-03-17
Abstract: The invention relates to a device for the variable actuation of the gas exchange valves of internal combustion engines, whereby a continuously revolving cam drives an intermediate member which carries out an oscillating, pure rotational movement and moves a drive member in accordance with the respective valve lift curve via a control cam. In order to modify the valve lift curve, the position of the rotational axis of the intermediate member can be modified along an advance curve. The rotational axis of the intermediate member is represented by a pin which is freely rotatable at its guide end and which carries cam plates that are linked therewith in a rotationally fixed manner. Said cam plates define either directly or indirectly the respective required position on the advance curve. The pin is rotated via a suitable joining element.

Patent CA-2568468-A1 (CA)
Title: Electric cooker
Inventor: KEHOE PAUL M
IPC: A23L5/10
Filed: 2006-11-17
Abstract: A device for cooking food is disclosed. The device has an elongated body for containing the food to be cooked with a heater at one end and a simmer temperature sensor at the other end. The heater initially brings the substance contained in the elongated member to a boil which is sensed by a boiling sensor. The boiling temperature sensor may be integral with the heater. Once a controller connected to the heater receives a signal from the boiling sensor indicating that the substance is boiling, the controller alternates the power to the heater between a simmer power level and a non-simmer power level which is lower than the simmer power level. The controller controls the power level of the heater in response to a signal from the simmer temperature sensor. The simmer temperature sensor sends a signal to the controller when the temperature of the substance at the end remote from the heater falls below a predetermined simmer temperature. In response to receiving the simmer signal, the controller sends the simmer power level so that the heater will heat the substance at the simmer power level. When the simmer temperature sensor senses that the temperature of the substance has risen above the simmer temperature, the simmer temperature sensor will discontinue sending the simmer signal. In response to the discontinuance of receiving the simmer signal to the controller, the controller will send a power level signal to the heater to apply a non-simmer power level to the heater which is lower than the simmer power level.    The device is particularly well suited for cooking pasta because the elongated shape of some pasta is easily accommodated in the elongated body, but the elongated body can be used to cook any other types of foods including vegetables and soups.
