Patent CA-2485531-A1 (CA)
Inventor: DAVIES LAURENCE W
IPC: B29C70/52
Filed: 2002-06-12
Abstract: A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. To the collated fibers is applied a resin so as to permeate through the layers and the materials are passed through a die to set the resin. The first and second layers are arranged to form first and second opposed surfaces of the part with the intermediate layer therebetween.  The resin is a two part urethane resin which has sufficient strength to prevent the fibers from the first and second layers at the first and second surfaces respectively from breaking through the surface on bending of the wall thus allowing the use of the rovings at the surfaces with the transverse fibers therebetween so that the transverse fibers can be formed from loose or chopped fiber material from rovings rather than more expensive mat.

Title: Control system for cooking appliance employing convection and radiant cooking
Inventor: GORANSON JAMES A
IPC: F24C1/04
Filed: 2005-02-28
Abstract: A cooking appliance includes a heating system which is preferably capable of combining radiant, convection, microwave and conduction heating techniques to perform a cooking operation. The cooking appliance includes a convection fan and at least one heating device. A controller is provided to regulate a triac to create a variable fan speed and variable heater intensity through phase angle firing. Essentially, an AC waveform provided to the fan motor and/or the heater resistor travels through the triac which is turned on by the controller at predetermined points in the AC waveform, with the delay from a zero point waveform crossing functioning to reduce the amount of power sent to the heater resistor and fan motor. When the signal from the controller is removed, the triac advantageously turns off at the next zero crossing of the AC waveform such that an operationally and economically effective control system is provided.

Title: Acid-coated sand for gravel pack and filter cake clean-up
Inventor: LEE LI-JEIN
IPC: E21B43/04
Filed: 2003-09-12
Abstract: A method of the preparation and utilization of polymerized alpha- hydroxycarboxylicacid-coated proppants for gravel pack and removal of filter cake that was deposited by reservoir drilling fluid. In a preferred example, polyglycolic-acid-coated sand is used to replace conventional gravel pack sa nd typically used for gravel packing. Under downhole conditions, the acidic by- product generated from the hydration of polyglycolic-acid-coated sand can break down acid-soluble and/or acid-breakable components embedded in the filter cake. This reaction enhances the filter cake removal and the flow of hydrocarbon from the producing formation. The polyglycolic-acid-coated sand may be produced by polymerizing a glycolic acid with a natural or synthetic proppant like 20-40 mesh commercial sand, at temperatures of about 210 ~F or higher.
