Abstract: A sequential air sampler is provided having a rotatable carrier adapted to support filter cassettes received from a supply magazine at a load station, transport them to a sampling station where gas flow is directed through that cassette, and then be transported to an unload station to be received by a storage magazine. A Geneva driver operated by a single motor provides intermittent rotation to the carrier between fixed positions. A cam rotates in concert with the Geneva driver so that a follower in reciprocating motion pushes up and then pulls down a pair of plungers for simultaneous cassette loading and unloading whenever the carrier is at one of its fixed positions. Magazines have magnetically actuated stoppers to keep the stack of cassettes in place until released. Magazines may also have a retaining lid with a position-adjustable piston to secure cassettes for transport.

Abstract: Methods and devices for etching patterns on interior surfaces of hollow objects are described. The method may include preparation of the interior surface of the object, such as pre-cleaning, and coating the interior surface of the object. A pattern may then be generated on the interior surface of the object by any of mechanical or manual scribing and peeling, laser ablation, or photoresist coating and laser exposure, development and hardening. The pattern is then etched using chemical etchants, and finished to remove remaining coating, provide surface passivation and/or protectant application. Mechanical and laser devices which may facilitate pattern generation are also described.

Abstract: A pulsation and particle suppressing continuous air flow system for air sampling instruments, particularly particle counters. An air pump occupies a portion of a sealed vacuum housing, with the other portion of the housing forming a surge chamber used to damp surges as the air pump attempts to pump air towards an air outflow port through an outflow pipe. The unoccupied volume of the surge chamber dampens or dilutes the surges at an air inflow port of the housing that is associated with an air sampling instrument, such as a particle counter. The air outflow port is associated with a filter for trapping particles originating inside of the air pump and associated motor while the interior of the housing itself traps particles originating outside of the air pump and motor.

Abstract: This invention provides a new category of inertial sensors (linear and angular accelerometers, gyroscopes, inclinometers and seismometers) called Molecular Electronic Transducers (MET). Unlike other inertial sensors, MET sensors use a liquid electrolyte as their inertial mass. The sensors do not contain any precision mechanical parts or springs, and are relatively simple and inexpensive to manufacture.

Abstract: Method to manufacture a personalized mattress (1) from a basic part (2) with a recess (2) and inserts (3, 4, 5), which comprises the following steps: determination of the anthropometric data of a person; determination of the optimum distances over which the mattress (1) has to be deformed in a number of positions so that the spine of the person in this position has the same shape, insofar possible, as when the person is standing upright; determination of the deformation characteristics that a mattress (1) must have at these positions; selection of inserts (3, 4, 5); fitting of the inserts (3, 4, 5) in the basic part (2).

Abstract: A particulate mass measuring device of the beta attenuation type featuring a sheath air plenum from which a radial sheath airflow pathway extends which is in fluid communication with an ambient air chamber. The radial sheath airflow from the radial sheath airflow pathway merges with an axial ambient airflow from the ambient air chamber deflecting particulate matter from surfaces of the ambient air chamber thereby increasing the accuracy of particulate mass measurements. The radial sheath airflow is particle free or substantially particle free. In other embodiments, the radial sheath airflow is used to deflect particulate matter in other particulate mass measuring devices, such as those that measure particulate mass in liquid and gas samples.

Abstract: Method for removing all types of particulate matter with exclusion of biological multiplying microorganisms in indoor environments characterized by comprising the following two steps:—the atomization of compounds that oxidize particulate matter to form complexes and to precipitate them;—the atomization of a liquid containing a mixture of spores of Gram-positive aerobic and/or of facultative anaerobic spore formers to act as nuclei for extra precipitation, to cover the precipitated particulate matter; and to metabolize precipitated particles and to take up precipitated particles by the Gram-positive bacteria/thereby preventing the precipitated particles to become airborne again;—whereby the drop size in both atomization steps is held between 5 and 50 ?m to yield a dry nebula.
