Title: Improvements relating to rotary piston machines
Inventor: WESLAKE-HILL IAN
IPC: F02G1/043
Filed: 1999-04-26
Abstract: A rotary piston machine adapts the Stirling principle and can operate as an engine or a heat pump. Two variable volume units (1, 4) have n-lobed chambers (3, 6) rotatable about a common axis at a first speed.  Each chamber contains an (n+l) sided piston (2, 5), these being rotatable about a different common axis at a different second speed, and cooperating with the lobes to form expanding and reducing sub-chambers. The first to second speed ratio is (n+1):n ducts (10, 11) incorporating regenerators provide intercommunication between the chambers (3, 6) and are open and closed by the relative piston rotation to exchange fluid or vapor between units. Heating may be provided for one unit, the expansion unit (1), and cooling for the other, the compression unit (4), and the ducts can also incorporate heating and cooling means.

Inventor: KALMAN JEFFREY M
IPC: A47L9/32
Filed: 2002-01-10
Abstract: A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A first supply tank 14 for concentrated cleaning fluid and a second supply tank 15 for clean water are mounted on an inverted Y-shaped handle assembly 12. The handle assembly includes a central member 334 with a hand grip 336 at its upper end and two splayed leg members 338, 342, 340, 344, which define a triangular shaped gap therebetween. The two tanks are removably mounted in the gap. The cleaning fluid tank is supported on a shelf 346, which spans the gap between the leg members. The water tank is pivotally mounted on two projections 374 on the leg members to allow for easy removal and replacement on the handle. The arrangement of tanks in the gap allows for large capacity tanks, a well-balanced handle, ease of removal of the recovery tank without the need for removing either of the two supply tanks, and ease of refill of the supply tanks.

Patent CA-2369793-A1 (CA)
Inventor: GUTHERMANN HOWARD E
IPC: A61B5/145
Filed: 2000-04-20
Abstract: L'absence d'une longueur de parcours optique définie dans des mesures in vivo pose problème pour le mesurage non invasif de concentration de substances à analyser. Ces problèmes peuvent être réduits si l'on combine les mesures effectuées à plusieurs longueurs d'onde avec le fait que l'activité fonctionnelle rénale normale assure un contrôle strict de la concentration d'eau dans le sang entier. De ce fait, la concentration d'eau dans le sang artériel peut servir d'étalon interne utile pour effectuer de telles mesures. Les mesures sont alors conduites de manière à éliminer la dépendance de la concentration à l'égard, d'une part de la longueur du trajet parcouru par le rayonnement éclairant, d'autre part des propriétés de dispersion du volume à travers lequel le rayonnement éclairant se propage. L'utilisation de ce procédé permet d'effectuer un calibrage amélioré des mesures d'absorption de constituants dans le sang artériel, ce qui donne des mesures absolues de concentration de constituants, tels que l'hémoglobine ou la glucose, dans le sang artériel.

Patent CA-2373023-A1 (CA)
Inventor: YAMAGIWA TOSHIO
IPC: B60C5/02
Filed: 2000-04-18
Abstract: In a sealant-containing tire, an outer liner is fastened to an inner surface of a tread of a tire body, and a sealant chamber that is filled with sealant is defined between the outer liner and the inner liner, with an air chamber filled with air also being defined within the inner liner. By making the inner liner of flexible rubber of a 300%  modulus of 60kgf/cm2 or less, not only is a puncture in the inner liner caused by a nail made smaller, but the puncture is rapidly made smaller after withdrawal of the nail so that the flowing out of air from the air chamber is delayed. The flexible inner liner can easily be deformed by the air pressure within the air chamber and the sealant within the sealant chamber is therefore rapidly pushed into a puncture of the tread by the air pressure, thereby effectively repairing the puncture.

Abstract: A differential gyrator based filter is disclosed that preferably has a first  gyrator connected to the positive input signal of the differential input signal and a second gyrator connected to the negative input signal of the differential input signal. A load capacitor is connected between the load terminals of the first gyrator and second gyrator, which minimizes the total  load capacitance required for the gyrator based filter. This implementation is believed to increase the overall density, reliability, yield, signal-to-nois e ratio and dynamic range of the gyrator based filter and related circuitry.</ SDOAB>

Title: Circuit interrupter with accessory trip interface and break-away access thereto
Inventor: HOOD TERESA I
IPC: H01H83/20
Filed: 2000-08-24
Abstract: A circuit interrupter including a housing having a cover connected to a base, separable main contacts within the housing, and an operating mechanism within the housing and inter-connected with the contacts. A trip mechanism is disposed within the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation. The trip mechanism includes a dual-purpose trip actuator biased upwards and positioned for vertical movement within the housing and having a top portion extending through the cover. The actuator includes a push-to-trip member and an interlock trip member. The trip bar assembly includes a multi-purpose trip member having a push-to-trip actuating region, an interlock trip actuating region, and an accessory trip actuating region. The push-to-trip member contacts the push-to-trip actuating region when the top portion is depressed, causing the trip bar assembly to rotate.  The interlock trip member contacts the interlock trip actuating region when the cover is removed from the base, causing the trip bar assembly to rotate.  The accessory trip actuating region is positioned to be contacted by the tripping member of the external accessory device and thereby cause rotation of the trip bar assembly.
