Le processus s'opère sous adduction d'air contrôlée et en présence d'une dépression de 0,5 à 0,95 bar (500 à 50 mbar absolue), générée par une pompe à vide. Les produits réactionnels gazeux sont ensuite refroidis à une température comprise entre 10 et 25  C, afin d'éviter que la pompe à vide (6) ne soit endommagée. Les produits réactionnels gazeux refroidis sont ensuite aspirés à l'aide de la pompe à vide.

Abstract: A device for accurately delivering aerosolized doses of a medicament disperses a measured amount of drug (40) in a measured volume of carrier gas (22) and transfers the resulting aerosol to a chamber (42) prior to inhalation by a patient. The chamber (42) is filled efficiently with the aerosol, and inhalation by the patient draws the aerosol dose into the lungs. This is followed by the inhalation of atmospheric air (96) that will push the initial dose well into the lung interior. The apparatus optimally includes a dose regulator (13a), a counter (13c), a clock (13e), a dose memory (30) and a signal (32) to indicate when a dose is ready by inhalation. Optimal chamber designs are disclosed.

Abstract: Disclosed is apparatus for enhancing the surface cleaning of a swimming pool having a skimmer inlet in a wall of the pool and the pool having peripheral water movement generally along the wall.  A first rigid plate, having an upper and lower edge and inner and outer ends is supported by a support generally vertically adjacent the skimmer inlet such that an upper edge of the first plate is above water level, the inner end of the first plate extends generally vertically downward intermediate the sides of the skimmer inlet and the plate extends inwardly at an angle with the pool wall in a direction opposite the direction of water movement.  The lower edge of at least the inner end of the first plate is substantially adjacent the bottom edge of the skimmer inlet.  A second plate extends outwardly from the first plate at an angle thereto such that when the apparatus is in operative association with the skimmer inlet, the second plate slants in the direction of water flow, has its lower edge below water level and its outer end downstream of the outer end of the first plate.  Debris on the surface of the water or close to it is directed by the first plate to the skimmer inlet.  The two plates also cause eddy currents behind the first plate, which current further directs water carrying debris toward the wall of the pool and to the downstream path of the skimmer inlet.  With the end of the first plate intermediate the sides of the skimmer inlet, water can still enter the skimmer from behind the first plate as well as in front of it.  The speed with which the surface of a pool is cleaned is significantly enhanced.

Abstract: For illuminating a reflector dish with two well-separated wavebands, two axially-directed, radially-spaced chokes are provided. One of the chokes is folded co-axially, and its profile includes a reltively large box. The box provides good control of matching, to minimise back-reflection, and also the box allows the choke grooves to be effectively deep, and yet the overall axial length of the chokes is small. Several configurations are shown, illustrating how one, or both, chokes may be axially folded.

Title: Synchronizer with self-energizing
Inventor: NELLUMS RICHARD ALEXANDER
IPC: F16D23/06

Granted: 2000-01-18
Abstract: A baulkring-type synchronizer (18) includes cone clutch friction surfaces (24,48 and 26,50) and jaw clutch teeth (36b,28 and 36c,30) for frictionally synchronizing and positive connecting gears (14,16) to a shaft (12). A torque ring (63) is mounted in a shift sleeve (34) for limited rotation relative thereto and non-axial movement relative thereto. The ring defines self-energizing ramp surfaces (74a,74b,74c,74d), blocker surfaces (76a,76b,78a,78b), and reaction surfaces (76c,78c). The ring self-energizing ramp surfaces engage self-energizing ramp surfaces (70a,70b,72a,72b) defined on an outer circumference of a hub (32) affixed to the shaft. The ring blocker surfaces engage blocker surfaces (44a,44b,46a,46b) affixed to baulkrings (40,42). The ring reaction surfaces engage reaction surfaces (44c,44d,46c,46d) affixed to the baulkrings. Synchronizing torque produced by friction surfaces is partly reacted across the blocker surface, the remainder is reacted across the reaction surfaces, and the sum of the total synchronizing torque is reacted across the self-energizing ramp surfaces. A shift sleeve (34) is slidably splined to the hub (32) and is moved by an operator shift force (F o) and an additive force (F a) provided by the self-energizing ramp surfaces. Both forces (F o and F a) react against the blocker teeth to engage the friction surfaces.

Abstract: An erasable writing medium composition suitable for use in porous tip pens and roller-ball pens is provided. The erasable writing medium comprises an emulsion having a continuous water phase and discontinuous phase that is comprised of a rubber. Pigment particles are exclusively associated with the discontinuous phase. Although the emulsion composition has a very low viscosity, very low surface tension, and very small rubber particle size, it is stable before use. Upon application of the composition to the highly ionic surface of standard stationary-type paper, the emulsion becomes unstable and the rubber agglomerates, and does not penetrate the paper. Upon drying, the pigment remains within the rubber phase thereby preventing the pigment from being absorbed by the writing surface. The rubber phase therefore forms a pigmented layer on the writing surface. The layer can be removed by erasure so that no pigment remains on the writing surface.
