Title: Domed compressed tampons
Inventor: KASAHARA MASAKI
IPC: A61F13/22
Filed: 1998-03-25
Abstract: An improved apparatus and method compresses a cylindrical blank (24) into a tampon which is dimensionally stable and which is provided with a domed insertion end. A cylindrical blank (24) is radially compressed and then introduced into a cylindrical axial compression chamber (50). The blank (24) is then subjected to an exhume axial overcompression. The closed insertion end of the compression chamber has a bore formed therethrough. The bore is generally coaxial and is adapted to accept a reciprocating ejection ram (58) having a ram surface facing into the chamber. When the ram (58) is seated in the first position, the ram surface and the insertion end wall of the compression chamber together form a smooth doming surface. The bore periphery is of a smaller diameter than the chamber and hence radially spaced from the side walls of the chamber, and the ram has sufficient clearance to move through the chamber and eject the tampon without interference from the walls of the chamber.

Title: A coating for the working surface of the cylinders of combustion engines and a method of applying such a coating
Inventor: BARBEZAT GERARD
IPC: C23C4/08
Filed: 2000-01-17
Abstract: Ferrous coatings of the cylinder working surfaces of combustion engine blocks have a content of bound oxygen in the amount of between 1 to 4% by weight. They are characterized by extraordinary properties as far as tribology and the possibility of processing, e.g. machining, are concerned.

Patent CA-2296983-A1 (CA)
Title: Ground fault circuit breaker
Inventor: FELLO JOSEPH P
IPC: H01H71/08
Filed: 2000-01-18
Abstract: A reverse fed single pole miniature ground fault circuit breaker includes a housing, a line termination on the lower portion of the housing, and a load termination on the upper portion of the housing. Separable contacts are disposed between the line termination and the load termination. A handle and operating mechanism form a manual mechanism for manually operating the separable contacts. The handle has an upper position in which the separable contacts are closed and a lower position in which the separable contacts are open. A ground fault circuit interruption trip circuit opens the separable contacts in response to predetermined ground fault current conditions and is powered through those separable contacts. In this manner, when a power source is electrically interconnected with the line termination on the lower portion of the housing, when the handle is in the upper position, and when there is none of the predetermined ground fault current conditions, the ground fault circuit interruption trip circuit receives power through the separable contacts.

Title: Integrated dram with high speed interleaving
Inventor: FANG HONG-GEE
IPC: G06F12/06
Filed: 1998-08-25
Abstract: An integrated circuit includes a controller and a memory to implement a graphics controller. The controller and memory are controlled by a common clock signal to operate synchronously with each other. The memory is organized in a plurality of storage arrays, organized in two banks. A set of bit-line sense amplifiers is provided for each bank. A  pair of row decoders decode a row address to select a row of data form each bank. The selected row of data is received by a pair of bit-lip sense amplifiers. A column decoder selects a column of data from the pair of bit-line sense amplifiers. A pair of multiplexers select one-half of the selected column in response to a HI/LO signal and then select the remaining half of the selected data in response to a change in value of the HI/LO signal. Main or data sense amplifiers amplify the output of the multiplexers to provide data outputs in the form of full swing signals.

Les générateurs (24) de tourbillons ainsi formés présentent des ouvertures entre les canaux (54, 56, 58) adjacents, ce qui assure une communication fluidique entre les différents canaux (54, 46, 48) et un écoulement uniforme à l'intérieur de ces derniers. Ce corps de remplissage (2) peut être utilisé dans les opération de mixage de fluides ou dans les opérations nécessitant un transfert de masse multiphase, telles que l'absorption ou la distillation. Si on lui ajoute un catalyseur cette structure se prête à la distillation catalytique. Le passage vertical tortueux imprime des turbulences aux fluides ainsi que de faibles chutes de pression dans les directions transversale et verticale, avec une rétention de liquide optimale.
