Abstract: Particles incorporating a surfactant and/or a hydrophilic or hydrophobic complex of a positively or negatively charged therapeutic agent and a charged molecule of opposite charge for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the particles are made of a biodegradable material and have a tap density less than 0.4 g/cm3 and a mass mean diameter between 5 .mu.m and 30 .mu.m, which together yield an aerodynamic diameter of the particles of between approximately one and five microns. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of poly(lactic acid) or poly(glycolic acid) or copolymers thereof. Alternatively, the particles may comprise a therapeutic, prophylactic or diagnostic agent and a material selected from the group consisting of surfactant and a molecule having a charge opposite to the charge of the agent and forming a complex thereto. The particles have a tap density less than 0.4 g/cm3 and a mass mean diameter between 5 .mu.m and 30 .mu.m. Exemplary surfactants include phosphoglycerides such as dipalmitoyl phosphatidylcholine (DPPC). The particles are administered to the respiratory tract to permit systemic or local delivery of a wide variety of therapeutic agents. Aggregation of particles before or during administration to the respiratory tract results in particles having an aerodynamic diameter larger than that of the fully dispersed particles. Aerodynamic diameters between three and five microns are advantageous for delivery to the central airways.

Title: Arc fault detector responsive to average instantaneous current and step increases in current and circuit breaker incorporating same
Inventor: RAE THOMAS CHRISTOPHER
IPC: H02H9/02
Filed: 2001-02-14
Granted: 2012-04-24
Abstract: An arc fault detector includes an average instantaneous current generator which averages the current over the fundamental period and produces a substantial output only where there are substantial variations in waveform between half cycles which is indicative of an arc. To discriminate over inrush currents, a pulse generator generates a pulse in response to the step increase in current caused by striking of an arc. An output circuit generates an arc signal when the time attenuated accumulation of pulses occurring in half-cycles in which the average instantaneous current is above a selected threshold reaches a predetermined level. To further discriminate over dimmers during turn on of a cold tungsten bulb, the ANDing with the average instantaneous current is delayed until a time attenuated accumulation of the pulses reaches a threshold value. The average instantaneous current can be approximated by a bandpass filter with a center frequency below the fundamental of the ac current. A second bandpass filter with a center frequency above the fundamental can be used as the pulse generator.

Granted: 2003-10-21
Abstract: Cette invention se rapporte à un parasol de jardin qui est associé à une table et à un système de chauffage radiant brûlant un combustible, ce parasol étant conçu pour éviter tout suréchauffement de la toile supérieure (20) grâce au montage du support (24), sur lequel repose la toile supérieure, dans la partie abritée par un réflecteur (28) qui converge vers le haut pour former une partie cheminée (34). Le réflecteur est fixé au logement de la chambre de combustion (18) par des pieds (32). En plus de réfléchir la chaleur radiante vers le bas sur la table et sur les personnes attablées, ledit réflecteur protège le support de toile supérieure (24) de la chaleur radiante et forme un conduit (34) pour la mise à l'air libre des produits de la combustion. Lorsque ces produits montent à travers la partie cheminée, de l'air plus frais est aspiré dans l'espace (30) compris entre le réflecteur (28) et le support de toile supérieur (24), empêchant ainsi l'air chaud d'y stagner. Le support de toile supérieure est monté sur le réflecteur et maintenu à distance au-dessus de lui par un certain nombre d'éléments d'espacement en céramique isolante (26).

Abstract: A suction hose assembly for an upright type vacuum cleaner including a flexible hose connected to an air inlet of a cleaner body with one end thereof, a suction pipe connected to the other end of the flexible hose with one end thereof and connected to an extension hose of the suction brush with the other end thereof, and a connection portion for movably connecting the suction pipe to the flexible hose so that the suction pipe can rotate relative to the flexible hose in a rotational direction. The connection portion includes a pair of connection protrusions preferably formed on one end of either the suction pipe or flexible hose, and spaced from each other by a predetermined distance, a pair of connection grooves formed on one end of whichever the flexible hose or suction pipe that the connection protrusions are not formed on, to receive the pair of connection protrusions, and at least one guide protrusion provided between a contact surface defined between the connection protrusions and a contact surface defined between the connection grooves, to reduce area of contact defined between the contact surfaces. Since the suction pipe and the flexible hose are rotatably connected with the other while presenting minimum relative contact due to the guide protrusions, thereby decreasing the frictional resistance during the rotation of the suction pipe relative to the flexible hose. As a result, the suction pipe rotates more smoothly, and a user can more easily use the cleaner with added convenience.
