Title: Icebreaking ship
Inventor: JANS PETER
IPC: B63B35/08
Filed: 1993-05-10
Granted: 2002-03-12
Abstract: To improve the maneuverability of an icebreaker whose forward quarter ie designed like a pontoon with an underside rising obliquely forward, which bears icebreaking means on its sides, the hull is equipped on both sides over the entire length of the ship with balcony-like flanks, whose balcony undersides drop off obliquely downward and lie in the level of the water line, such that with the turning of the ship, they break of the edges of the ice. Furthermore, the underside of the bow in the vicinity of the icebreaking means is designed wider than the water line of the afterbody, to thus provide a clearance between the edges of the ice and the hull.

Patent CA-2100150-C (CA)
Inventor: FALCK PETER LESLIE
IPC: F16H61/06
Filed: 1993-07-08
Granted: 1997-03-18
Abstract: The hydraulically operated brake and clutch elements (controlled by proportional control valves) of a vehicle powershift transmission have fill pressures which are calibrated by a method wherein the output shaft of the transmission is disconnected from the vehicle drive shaft so that the transmission output shaft is free to rotate and certain ones of the plurality of the control elements other than the control element being calibrated are fully pressurized in order to prevent rotation of a part of the control element being calibrated.  The engine is run at a predetermined speed and the pressure applied to the control element being calibrated is gradually increased while engine speed is monitored.  When the monitored engine speed changes by predetermined amount, a value is saved corresponding to the calibration pressure.  The transmission is automatically shifted to neutral if vehicle motion is sensed.  The volume of hydraulic fluid required to initially engage the control element may be calibrated in a similar manner.

Title: Improved diffusion-type gas sample chamber
Inventor: WONG JACOB Y
IPC: G08B17/117
Filed: 1993-07-16
Granted: 1997-01-21
Abstract: The improved sample chamber includes an elongated hollow tube (12) closed at one end (14) and having specularly-reflective inwardly facing surfaces(16). A source (26) of radiation and a detector (28) of radiation are mounted side by side in the open end of the hollow tube, both facing the closed end. A plurality of filtering apertures (20) are formed in the tube (12), and each aperture is covered by a sheet (22) of a semipermeable membrane that serves to prevent airborne particles larger than a predetermined size from entering the chamber while not interfering with the free diffusion of the gas to be measured into andout of the chamber. The use of an elongated hollow tube that is closed at one end results in no loss in the efficiency with which the radiation is conducted from the source to the detector while decreasing the external length of the chamber by 50 percent.

Abstract: An endoprosthesis for implantation in vessels of the human or animal body is shaped as a tubular latticework of filaments with the form of a helical line, which form two interwoven groups with the opposite sense of rotation, which consist in each case of several filaments twisted against each other.     Each filament has a composite material (2) with continuous reinforcement fibers (4) embedded in support (3) made of a high-strength thermoplastic, preferably polyetherether ketone (PEEK) or polyethersulfone (PS), the said fibers being made of high-strength inorganic material, preferably carbon, glass, or Kevlar.  The composite material (2)  can be surrounded by a shell (5), which consists preferably of material corresponding to the support (3), but may contain admixtures, e.g., medications.  For the uptake of medications or other active ingredients the shell (5) can be fashioned as porous.  A contrast medium can be added to the shell or support.     For the fabrication of the composite material (2), the reinforcement fibers (4) are sprinkled with the support in powder form and pulled through a heated die, i.e., pultruded.  The shell (5) can then be applied in a similar way to the composite material (2), whereby a granular soluble material such as salt, which can then be washed out, can be added to the shell material to produce a porous structure.

Abstract: L'invention concerne une valve d'exhalation (14) pour masque antipoussière (10) constituée d'un clapet flexible (24) qui vient en contact avec un bord d'étanchéité courbe (30) d'un siège de valve (26) lorsque la valve (14) est en position de fermeture. La courbure du bord d'étanchéité (30) correspond à la courbe de déformation formée par le clapet flexible (24) lorqu'il est fixé en porte-à-faux à une extrémité et qu'il est exposé au niveau de son extrémité libre à une force uniformément répartie et/ou à une force correspondant à au moins le poids de la partie libre du clapet flexible. Une courbure de joint d'étanchéité correspondant à un clapet flexible exposé à une force uniformément répartie permet au clapet flexible (24) d'exercer une pression généralement uniformément répartie sur le bord d'étanchéité afin d'assurer une étanchéité satisfaisante. Une courbure de point d'étanchéité correspondant à un clapet flexible exposé à une force d'au moins le poids de la partie libre du clapet permet au clapet (24) d'être maintenu contre ledit bord d'étanchéité (30) dans n'importe quelle orientation statique avec une force minimale. On dispose ainsi d'un masque antipoussière (10) produisant une chute de pression exceptionnellement faible lors de l'exhalation.
