Patent CA-2242666-A1 (CA)
Inventor: SHIM HOSUP
IPC: C12N5/10
Filed: 1997-01-08
Abstract: On extrait des cellules germinales primordiales d'embryons post-blastocytes d'un ongulé, en prélevant, notamment, des cellules germinales primordiales dans les replis gonadiques d'embryons de porc âgés de 25 jours ou d'embryons de bovins dont l'âge se situe entre 34 et 40 jours. On cultive ces cellules germinales embryonnaires sur une longue période, plus de 30 jours, ce qui donne des cellules ressemblant, de par leur morphologie et le maintien de leur multipotence, à des cellules embryonnaires souches. Il est possible de maintenir en culture les cellules ainsi obtenues plusieurs mois durant et de les modifier par génie génétique en faisant intervenir des techniques de recombinaison homologue et ce, afin d'introduire un matériau génétique souhaité dans le complément génique de la cellule en un site désiré. On est en mesure d'introduire la cellule ainsi modifiée par génie génétique dans un blastocyte obtenu à partir d'un animal de la même espèce que celle chez qui a été dérivée la cellule afin de fabriquer un ongulé chimère, susceptible, du fait de sa mise au point par génie génétique, de produire des substances à usage pharmaceutique désirées.

Title: Casting rolls
Inventor: PERRY ROBERT
IPC: B22D11/06
Filed: 1998-08-06
Abstract: A casting roll 1 for casting molten metal and forming it into a solid continuous strip form comprises a shell 6 coupled to a drive shaft 91. A plurality of shaper units 8, 12 is arranged inside the shell, to allow the shapeof the shell to be adjusted. The drive shaft 91 passes through a stationary support shaft 9 of large diameter and is coupled to the shell 6 via epicyclic gearing 92,93,95. The shaper units act between the inside of the shell and the support shaft, which, being massive, acts as the primary structural element to absorb the reaction forces from the shaper units. A further set of shaper units spaced 180° round the shaft may be provided, to enable the shape of the shell to be controlled more accurately.

Patent CA-2245453-A1 (CA)
Title: Web stabilizing device
Inventor: BROWN DALE A
IPC: D21G9/00
Filed: 1998-08-24
Abstract: A web support foil positioned adjacent to a Yankee dryer above a creping doctor. The foil supports the web as it leaves the dryer. Mounted to the top of the foil is an adjustable air deflector which is positioned tangent to the Yankee dryer. The air deflector blocks air moving along the web. A slotted opening draws air from a leading-edge pocket collecting fibers which are broken loose during the creping action. The web is held against the bottom side of the foil by one or more air jets which are directed over the bottom surface on the foil. The jets of air function as coanda air jets and prevent the web from sticking to the bottom surface of the foil while creating a Bernoulli effect which holds the web against the bottom of the foil.

Title: Lumber production machine not requiring seasoning and manufacturing method thereof
Inventor: IZUMI HYOGO
IPC: F26B21/10
Filed: 1998-08-31
Abstract: To break down the common sense of lumber seasoning in that losses such as cracks and deformation are generated in a large quantity during lumber seasoning, and to form lumber that does not generate losses.  Because the governments and the lumber academies in the world follow in the footsteps of the seasoning theory established on the presumption that the natural contained water contained in the vessels, capillary tubes, and cell cavities of the lumber tissue are unable to be uniformly liberated, take it granted that this premise is unable to be changed, and allow the industry to produce lumbers under this premise, forests in the world are cut down in large quantities. By breaking down the premise of this lumber seasoning theory by lumbering and treating the lumber in the pressure vessel, the lumber can be formed into the one that can uniformly liberate the contained water contained in the lumber structure and that does not need any artificial seasoning that is popularly practiced in the world, thereby remarkably improving the yield ratio.

Patent CA-2250702-A1 (CA)
Inventor: BASERGA RENATO L
IPC: A61K38/00
Filed: 1997-04-01
Abstract: Active Survival Domains in the Insulin-like Growth Factor-I Receptor (IGF-IR) required for transmitting the survival signal in vertebrate cells have been identified. In FL5.12 cells transfected with wild type IGF-I receptors, IGF-I provided protection from IL-3 withdrawal analogous to the protection afforded by expression of Bcl-2. Under the same conditions, IGF-I did not have a significant mitogenic effect on FL5.12 cells expressing IGF-I receptors. An IGF-I receptor with a mutation at the ATP-binding site did not provide protection from apoptosis. However, mutations at tyrosine residue 950 or in the tyrosine cluster (1131, 1135, and 1136) in the kinase domain resulted in receptors that retained survival function. In the C-terminus of the IGF-IR, mutation at tyrosine 1251 and at histidine 1293 and lysine 1294 abolished apoptotic function, whereas mutation of the four serines at 1280-1283 did not affect survival. Surprisingly, receptors truncated at the C-terminus had enhanced anti-apoptotic function. The compositions and methods of the invention are useful for modulating apoptosis in vertebrate cells.

Abstract: An operative element mover (22) is used as a part of an ultrasound imaging or other catheter system (2) including a hollow sheath (6) and a case (16) housing a rotary driver (10). A drive cable or other connecting member (8) is disposed within the sheath with a transducer (24) at its distal end (26) and its proximal end (12) coupled to 2he rotary driver. The rotary driver rotates the transducer about the longitudinal axis (14) of the sheath. A hemostasis valve (50) anchors the sheath to the patient where the sheath enters the patient.  The transducer mover (22) is used to move the drive cable along the longitudinal axis and includes a body (38) fixedly mountable to and dismountable from the case and a movable anchor post (40). The anchor post is clipped to the sheath and is moved by a sheath anchor drive (46) to translate the sheath from or toward the case. This causes the transducer to move within the sheath in a proximal or distal longitudinal direction (52).

A card reading and writing device is associated with a vending machine, access controller or the like, and reads the account balance of a card presented by a user, enables vending and debits and re-writes a new balance to the card. Value adding machines can enter an account balance to add to an existing balance in a similar manner. At least one of the value adding apparatus and the card reading and writing device, and preferably both, contains a memory buffer that stores a log of the unique codes and the latest account balances of each successive user card to which an account balance was written. The log can be searched for a unique code and the most recent balance read out, if a card becomes unreadable. The log is preferably stored in a recirculating memory buffer of the value adding apparatus, which holds data on a predetermined number of most recent transactions only.
