Filed: 1998-02-05
Abstract: A selection method for selecting from a population of cells one or more selectable genetically transformed cells is described. In the method, the population of cells comprises selectable genetically transformed cells and possible non-transformed cells. Each of the selectable genetically transformed cells comprises a first expressable nucleotide sequence and optionally a second expressable nucleotide sequence. In the method, a component or a metabolic derivative thereof when present in a low concentration in a medium is a nutrient for both the selectable genetically transformed cells and the non-transformed cells. In the method, the component or the metabolic derivative thereof when present in a high concentration in a medium is toxic to the non-transformed cells. The first nucleotide sequence codes for a gene product capable of converting the component or the metabolic derivative thereof when present in a high concentration in a medium to a nutrient for the selectable genetically transformed cells. The method comprises the step of introducing the population of cells to a medium, wherein the medium optionally comprises a high concentration of the component or the metabolic derivative thereof. In the method, the component or the metabolic derivative thereof is a source of both carbohydrate and nitrogen for the selectable genetically transformed cells. Alternatively, in the method if a portion of the component serves as a metabolic substrate and is metabolically converted to a derivatised substrate, then that derivatised substrate is capable of providing an allosteric effect on the gene product.

Patent CA-2283775-A1 (CA)
Title: Trench-isolated bipolar devices
Inventor: NORSTROEM HANS
IPC: H01L29/732
Filed: 1998-03-18
Abstract: In order to produce an electrical connection to an inner layer such as a bottom diffusion (103), which has a good electrical conductivity and is located inside a bipolar semiconductor device isolated by trenches (119) and which for example forms a subcollector of a NPN-transistor, a hole (157) in a trench is used. The hole is filled with electrically conducting material and extends from the surface of the device to the bottom diffusion (103), so that the electrically conducting material in the hole is in contact therewith. The hole (157) is made aligned with a sidewall of the trench (119) by using selective etching. The hole can be made at the same time as contact holes for metallization are made and then also be filled in the metallization step, to contact the bottom diffusion. For a lateral PNP-transistor the hole can be made as a closed groove constituting the outer confinement of the base area, passing all around the transistor. The outer sidewall of such a closed trench can, as seen from above, be bevelled by 45~, so that no inner corners having too small angles are found in the trench, what facilitates the filling with oxide.

Title: Steerable catheter with rotatable tip electrode and method of use
Inventor: ORGAN LESLIE
IPC: A61B18/14
Filed: 1997-04-11
Abstract: A catheter, used e.g. for cardiac ablation, has a handle, a shaft, and a J-bendable distal end containing tip and ring electrodes. The tip electrode is axially rotatable and has insulated and uninsulated portions. As the tip electrode is rotated, the impedance between it and a reference level is observed. When the impedance reaches a maximum, this indicates that the uninsulated portion lies against the tissue and the insulated portion faces the bloodstream. An electrogram can be taken from the electrode, or an ablation current can then be applied to it. Short circuiting of the signal or current through the blood is thus reduced.
Patent CA-2287118-A1 (CA)
Inventor: MARVASTI FAROKH ALIM
IPC: H04N19/89
Filed: 1999-10-25
Abstract: A method of error concealment or correction is disclosed, suitable for signals such as speech, image and video signals, and particularly for such signals as transmitted over wireless and ATM channels. The method has improved stability for large block sizes and bunched errors. It is based on a modification of the discrete Fourier transform which is equivalent to a permutation of the Fourier coefficients.  Thus, as with the conventional Fourier transform, setting a contiguous set of coefficients equal to zero in the transmitted signal enables error concealment techniques to be used at the receiver. However, with the modified transform, the zeroes are not bunched together in the spectrum, so the instability problems that arise when the conventional Fourier transform is used are mollified, and much larger block sizes can be used.

IPC: B30B9/30
Filed: 1999-11-26
Abstract: A system and method for compressing scrap metal.      The scrap metal is compressed in a portable container.      The container rests on two scales that rest above the ground surface. The fullness of the container is primarily evaluated based on the weight of the container.      The scrap metal is initially delivered to a static compactor to which the container is mated. The compactor includes a ram that forces the scrap metal into and compresses the scrap metal in the container. The weight of the container is continually monitored while the container is mated to the compactor. The actuation of the ram is controlled so that, as the amount of scrap metal in the container increases, the frequency with which the ram is actuated increases. After the volume of scrap metal in the container increases above a certain level, each actuation of the ram actual comprises running the ram through plural extension and retraction cycles. The weight of the container is employed as the primary variable upon which the fullness of the ram is evaluated.      The pressure of the hydraulic fluid that actuates the ram is also monitored. Even if the container weight is below a set weight, if the hydraulic pressure exceeds a set pressure, the container is considered full. The container has a tapered profile. Ribs extend inwardly from the inner surfaces of the panels forming the container. These features ensure that, when the container tipped, gravity provides sufficient force for drawing the compressed scrap metal out of the container.
