摘要:
The invention relates to a method and an apparatus for cleaning ambient air by means of an adsorption unit (8) arranged in a vehicle, which vehicle includes a combustion engine (1) and a ventilation system (5, 6, 7, 8, 9, 10, 11) for a passenger compartment. Adsorption takes place whether the engine (1) is running or switched off. In adsorption mode, a fan (11) is operated to force ambient air from an inlet (6) to the ventilation system in a first direction, through an adsorption unit (8), and out of an outlet (10) of the ventilation system. In desorption mode the engine is running and air is supplied to a first heating means (13). The heated air is passed through the adsorption unit (8) to release the pollutants and regenerate said unit. The air containing the pollutants is passed through a second heating means (4, 16) and is then passed through the first heating means (13) to heat the said ambient air. Finally, the polluted air is drawn from the heat exchanger (13) to an intake conduit (3) of the combustion engine (1).

Method and a device (1) at a motor driven line winch (2) for sailing boats comprising a rotatably mounted line drum (3) around which a line (4) for sail and halyard is windable. According to the invention, more than one electrical motor is arranged in order to in different manners in different engagement patterns be possible to be coupled together in order to thereby actuate the winch (2) by different desired power and be able to optimize the total efficiency of the device.
摘要:
A duct system, especially an intake manifold for an internal combustion engine, having flap valves (13) for selective opening and closing of at least some of the ducts. The valves should be continuously adjustable in position in order to produce a swirl in the combustion airflow. To achieve this a high degree of angular precision is required in the positioning of the valves. Intake manifold manufacturing tolerances need to be compensated during assembly of the valves. Valve adjusting mechanisms are provided on the axles of the valves or in the mechanical connections of the valve gear pertaining to the valve drive mechanism.

A face mask is provided which is adapted to be mounted an inhalation device, e.g., an inhaler or spacer, having a body. The mask includes an annular adaptor part which is to be connected to one end of the body, and a funnel-shaped face engaging portion having a narrow end that is joined to one end of the adaptor part. The wide end of the face engaging portion has a free edge that is adapted to engage the face of an infant around the infant's mouth and at least a part of the infant's nose, and is resilient so that it is adaptable to the shape of the infant's face. The free edge of the wide end of the face engaging part is provided substantially entirely in a plane which forms an angle of about 10.degree.-25.degree. with a plane perpendicular to the extended longitudinal axis of the adaptor part.
摘要:
A method for controlling power to at least one power consuming device includes detecting at least one first operational parameter and at least one second operational parameter, establishing a power value based on the detected values of the first and second operational parameters, and controlling the power consuming device in response to the established power value.
摘要:
A method (and device) of removing material residues, from cores to make possible reuse of them in the same manner as new and unused cores a number of times wherein cores with material residues in the form of a number of material turns are processed using a mechanism for lifting and tearing the material residues for subsequent simple removal thereof, the mechanism for lifting and tearing of the material residues is displaced along the core and the mechanism for lifting and tearing of the material residues is displaced from a position in on the core out towards and past the ends of the core.

The present invention relates to a magnetic resonance imaging (MRI) method, in particular to a MRI method enabling early detection of myocardial ischemia and to compounds for use as MR contrast agents in the method.
摘要:
A flow control valve including a movable part and a housing for accommodating the movable part may be produced by molding the components in sequential steps. Preferably, the housing is molded in a first step and the movable part is molded in an at least partially closed position in a second step in the same mold. This method enables the surface of the housing to serve as at least a portion of the mold for forming a substantially sealing portion of the movable part such that a very close tolerance between these components is achieved. The movable part is preferably a butterfly disc and the housing is preferably a butterfly valve housing.
