Patent CA-2278096-A1 (CA)
Inventor: TRONSGARD KEN
IPC: E06B9/24
Filed: 1999-07-20
Abstract: A two tier venetian blind comprises an upper and a lower tier of slats suspended from a blind control mechanism; a front upper control cord and a back upper control cord for tilting the upper tier of slats; a front lower control cord and a back lower control cord for tilting the lower tier of slats; and a lift cord passing through a lift cord hole in each slat in the upper and lower tiers of slats. To avoid having the lower control cords hang when the blind is raised, the front lower control cord passes through the lift cord holes in each slat in the upper tier of slats and the back lower control cord passes around the back upper control cord at a plurality of points along the back upper control cord. In this way the lower control cords are gathered as the blind is raised.

Title: Oven for baking dough
Inventor: ACKNIN CHRISTIAN
IPC: F24C15/16
Filed: 1998-02-19
Abstract: The invention concerns a microwave oven (1, 2) for baking dough, characterised in that it combines the use of the partial vacuum (11) to bring about the expansion of the dough and one or several cooking means, for example microwaves (9) and infrared (6), used simultaneously or successively, for fixing it in expanded position and/or cooking the ingredients on the dough. These cooking means can be combined with the rotating motion of the baking dough about a vertical axis (15, 16, 17) and along the length of this axis (4, 21) for homogenising the cooking. The treatment to which the dough is subjected inside the oven, the choice of the cooking system(s) to be operated and the cooking time, is programmed or programmable based on the dough to be baked and the desired result, or is automatically controlled by the reading of a code posted beside the dough on the hot plate bearing the dough (16). The device can comprise an automatic system for handling the dough-bearing hot plates for inserting them in the oven and removing them therefrom.

Title: Nmr log processing using wavelet filter and iterative inversion
Inventor: CHEN SONGHUA
IPC: G01R33/44
Filed: 1999-10-27
Abstract: A method of nuclear magnetic resonance (NMR) well log processing. A wavelet decomposition of an NMR echo train is performed. The resulting small scale coefficients, which may be discretely or continuously indexed by scale, in alternative embodiments, are windowed, and a first reconstruction generated therefrom by inverse wavelet transformation. The reconstructed signal is inverted and fit to a multiexponential model. Further refinements may be generated by iteratively decomposing the fitted signal at a preselected maximum scale, increasing at each iteration, generating a new coefficient by replacing the corresponding portion of the previous coefficient with the coefficient at the current scale, reconstructing the signal with the new coefficient, and fitting the signal so reconstructed to the relaxation time distribution.

Patent CA-2302550-A1 (CA)
Title: An improved flow, axially-rotated, split venturi valve
Inventor: WALRATH DAVID E
IPC: E03B9/02
Filed: 1998-09-04
Abstract: The present invention provides an axially-rotated valve which permits increased flow rates and lower pressure drop (characterized by a lower loss coefficient) by using an axial eccentric split venturi (34) with two portions where at least one portion is rotatable with respect to the other portion. The axially-rotated valve typically may be designed to avoid flow separation and/or cavitation at full flow under a variety of conditions.  Similarly, the valve is designed, in some embodiments, to produce streamlined flow within the valve. An axially aligned outlet may also increase the flow efficiency. A typical cross section of the eccentric split venturi (34) may be non-axisymmetric such as a semicircular cross section which may assist in both throttling capabilities and in maximum flow capacity using the design of the present invention. Such a design can include applications for freeze resistant axially-rotated valves and may be fully-opened and fully-closed in one-half of a complete rotation. An internal wide radius elbow typically connected to a rotatable portion of the eccentric venturi may assist in directing flow with lower friction losses. A  valve actuator (48) may actuate in an axial manner yet be uniquely located outside of the axial flow path to further reduce friction losses. A seal may be used between the two portions that may include a peripheral and diametrical seal in the same plane. A seal separator may increase the useful life of the seal between the fixed and rotatable portions.
