Title: Transducer-tipped intrauterine pressure catheter system
Inventor: ALLEN GEORGE R
IPC: A61M25/01
Filed: 1996-04-24
Granted: 2006-10-03
Abstract: A transducer-tipped intrauterine pressure catheter system for measuring, and delivering to an external monitor a signal representative of, the pressure in the uterus of a woman in labor. The system has a disposable catheter with an affixed asymmetric tip. A disposable, slotted, C-shaped introducer engages and positions the catheter. A reusable monitor cable has a second connector (which engages a.first connector on the end of the catheter) on one end and a monitor connector (which engages the monitor) on its opposite end; the monitor cable transmits electrical signals from the first connector to the monitor. A test member is proximate the monitor connector on the monitor cable. The test member includes test circuitry assuring that the monitor cable, the second connector, and the monitor connector are operational. The test member also includes circuitry to "zero" the system. The system may also have a disposable luer fitting engaging the amnio lumen of the catheter and providing direct communication, through the amnio lumen, into the uterus. The luer fitting allows fluid samples to be withdrawn from, and fluids to be infused into, the uterus. An anti-bacterial coating may be bonded to the catheter, the tip affixed to the catheter, and the introducer.

Title: Rondelle a grande surface
Inventor: OSTERLE HELMUT
IPC: F16B43/00
Filed: 1994-12-05
Granted: 2005-02-08
Abstract: Une rondelle (1) à grande surface est pourvue d'une ouverture (5) conçue pour l'introduction d'un élément de fixation. Des éléments de contact (13) qui augmentent le contact avec une plaque et/ou une bande à assujettir sont situés sur la surface de la rondelle (1) tournée dans le sens de fixation. Des pièces d'écartement (17) saillantes en forme de languettes (26), qui entrent en action lorsque plusieurs rondelles (1) sont empilées, sont situées en outre sur la face inférieure de la rondelle (1). L'extrémité libre de ces languettes (26) peut s'appuyer sur la face supérieure de la rondelle directement au-dessous, ce qui permet d'empiler les rondelles sans que les éléments de contact (13) des différentes rondelles (1) n'entrent les uns dans les autres. On peut ainsi séparer aisément des rondelles individuelles (1) d'une pile de rondelles, que ce soit par mise en rotation ou par déplacement de la rondelle située en bas de la pile.

Patent CA-2179625-C (CA)
Title: Optical polarizer
Inventor: OUDERKIRK ANDREW J
IPC: B32B7/023
Filed: 1994-12-20
Granted: 2004-10-26
Abstract: A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two polarizers provides a high reflectivity of one polarization and high transmission for the perpendicular polarization from the reflective polarizer side of the combined polarizer, and high absorption and transmission for light of orthogonal polarization from the dichroic polarizer side. The combination also reduces iridescence as seen in transmission and when viewed in reflection from the dichroic polarizer side. The increased extinction ratio and low reflectivity of the optical polarizer allows use of a lower extinction ratio dichroic polarizer in applications requiring a given extinction ratio and high transmission.

Abstract: Une pièce rapportée de fraisage comprend un côté supérieur (2), un côté inférieur (3) et des surfaces latérales (4) reliant ces derniers. Une saillie (17) en retrait par rapport à l'arête de coupe principale adjacente (5) et une arête de coupe d'angle (6) est prévue au niveau de chaque angle de coupe actif. Une arête de planage (16) produisant la surface sur la pièce à usiner est prévue au niveau de l'arête frontale supérieure.

Abstract: Metallurgical slag is expanded to produce a lightweight solid by forming a stream of molten liquid slag of controlled rate of flow and mixing the stream of slag with a controlled quantity of water and flowing the interacting mixture of slag and water into a receptacle. The interaction between slag and water is allowed to proceed for a predetermined period of time to form an expanded solid without theaddition of any additional cooling water which would otherwise quench the material and vitrify it. In the receptacle, a vaned rotor operates to segment the interacting mixture of slag and water and project the segmented mixture through the air for collection into a heap.

Abstract: When a power supply to a mobile station is turned on, mobile station identification information is read out from a non-volatile storage of a subscriber information module. A module identification information is read out from the non-volatile storage of the mobile station. The mobile station identification information which is read out is collated against the own mobile station identification information, and module identification information which is read out is collated against identification information for the loaded subscriber information module. If the module identification information does not coincide, the communication processing information is read out from the loaded subscriber information module and is stored into the non-volatile storage of the mobile station to update its content. Identification information for subscriber information module is stored into the non-volatile storage of the mobile station to update it. Identification information for the mobile station is stored into the non-volatile storage of the subscriber information module to update it. Subsequently, communication processing information stored in the non-volatile storage of the mobile station is read out to set up a condition which enables a communication.  When the collation indicates a "coincidence", communication processing information which is previously stored in the non-volatile storage of the mobile station is read out to set up a condition which enables a communication.

Title: Removable display surface
Inventor: RICHARDS ERIC W
IPC: B65D25/36
Filed: 1998-07-20
Granted: 2004-11-23
Abstract: A precisely measured removable cover for reusable beverage containers. A covering of independently resilient material is precisely cut to fit a given size and shape of pot, and the material has imprinted on it a desired promotional or advertising message and/or graphics. The covering material is removably fastened with releasable closures to the outside of the pot in such a way as not to impair significantly the natural independent resiliency of the material. Thus, dents in the pot do not generally show in the covering surface because it retains its independent resiliency, even if the blow was delivered through the covering surface.  Messages may be changed as often as suits the promotional and decorative needs of the owner of the pot, so the display surface is always timely and in top condition. An optional "window" permits display of interchangeable labels on the inside of the covering.  When the display surface is fully removed, the original surface of the pot is substantially restored to its former appearance. Optionally, a protective plastic covering or overlaminant is attached to the print side of the covering material, so that when the printed cover is in its removed state, the printing will not be accidentally damaged by scratching. Some embodiments employ a nylon fabric cover material with promotional printing.
