  • Publication number: 20070257134
    Abstract: The invention relates to a nozzle system for a delivery device for liquids, wherein the nozzle system comprises a nozzle and a device which fixes the nozzle in the delivery device. The delivery device, an atomizer, has a liquid reservoir from which a liquid is forced through the nozzle under pressure. The nozzle fixing means may itself be secured by a second fixing, e.g., in the form of a check nut, or the fixing may itself be a check nut. According to the invention the fixing means on the nozzle outlet side has a specific geometry which minimizes the proportion of dispensed liquid deposited on the fixing means. Preferably, the present invention is part of a propellant-free device for nebulizing pharmaceutical liquids.

  • Publication number: 20050263151
    Abstract: The invention relates to a powder inhaler (1) with mouthpiece (2) for dispersing pharmaceutical medicament formulations, which comprises an auxiliary energy source in the form of a pressure medium system (3), having a device for supplying (6) a powder formulation (7), while on activation of the pressure medium system a gaseous pressure medium (8) released by the pressure medium system (3) forms an aerosol (9) with the powder formulation (7) such that the powder particles are present in the gaseous pressure medium (8) in dispersed form. This is achieved by means of a powder inhaler (1) comprising a multi-channel nozzle, the channels of which are inclined to one another at an angle such that the aerosol jets flowing through them meet one another downstream behind the nozzle (10).

  • Publication number: 20050150378
    Abstract: Using a high pressure rotary adsorbent wheel, a high value compressed gas feed can be purified by concentrating the impurity such as water, condensing it out, before final purification. Instead of exhausting gas from the system, the effluent can be put back into the feed at a point prior to condensation of the high value gas feed, and therefore the entire feed is purified without any high value gas feed going into a waste stream.

  • Patent number: 5142864
    Abstract: This invention relates to a process for minimizing hydrocarbon emissions from the exhaust streams of engines when the engines are first started, i.e., cold start. The process involves sequentially flowing the engine exhaust stream, which typically contains hydrocarbons, carbon monoxide and nitrogen oxide pollutants over a catalyst, the turbine side of a turbocharger and an adsorbent bed before discharging it into the atmosphere. The initial low temperature of the exhaust stream necessitates the use of the adsorbent bed. When the adsorbent bed (containing one or more molecular sieve beds) warms up (about 150.degree. C. to about 200.degree. C.), the majority of the exhaust stream is diverted around the adsorbent bed, while a minor portion is used to desorb the hydrocarbons adsorbed on the adsorbent bed and flowing these hydrocarbons through the compressor side of the turbocharger and then into the engine exhaust stream in front of the catalyst.
