Title: Process for recovering condensable compounds from inert gas-condensable compound vapor mixtures
Inventor: DINSMORE HAROLD L
IPC: B01D53/04
Filed: 1993-10-04
Granted: 2004-03-30
Abstract: An improved process for recovering one or more condensable compounds from an inert gas-condensable compound vapor mixture is provided. The inert gas-condensable compound vapor mixture is flowed through a first bed of solid adsorbent whereby the condensable compounds are removed from the mixture and a residue gas stream comprised of substantially condensable compound-free inert gas is produced and disposed of, e.g., vented to the atmosphere. A second bed of solid adsorbent is evacuated by vacuum pumping using a cooled liquid seal vacuum pump. As the resulting inert gas-condensable compound vapor mixture is contacted with the cooled seal liquid of the liquid seal vacuum pump, a major portion of the condensable compounds are condensed. The condensed compounds are recovered and a portion thereof are cooled and recycled as cooled seal liquid for the vacuum pump.

Abstract: Devices (10), such as filters, catalytic converters and the like, for separating selected substances from a stream of fluid. The device is made of continuums (23A, 24A, 31, 32, 33, ...) made of filter material and arranged so that substantially all of the fluid passing through the filter must pass through the separation material. In one emb odiment the continuums, typically textile yarn, are arranged parallel to each other in planar arrays, such arrays are then super imposed to form a laminated grouping with each continuums in each array angularly oriented with respect to and in contact with continuums in each adjacent array. Two distinct patterns of internal distribution paths for the fluid being processed are thereb y formed by spacing between continuums, In preferred embodiment, the constituent continuums in each array cross those in ea ch next adjacent array channels formed by the aggregations of crossovers substantially at right angles to the plane of array a nd/or intra-array channels, that translaminar channels provide substantially straight channels that are at right angles to the planes of the arrays. Some translaminar channels are adapted for use as inlets (X) and others as egress (O) channels.

Title: Oxygen consumption meter
Inventor: MAULT JAMES R
IPC: A61B5/08
Filed: 1991-06-27
Granted: 2001-09-04
Abstract: An indirect calorimeter for calculating the metabolic rate of a subject by measuring the oxygen consumption during respiration over a period of time includes a gas flow meter (42) providing output electric signals to a microprocessor (20) which drives a display and printer. The output of the flow meter (42) is connected to a mouthpiece (12), The exhaled gas passes through a CO2 scrubber (30) and then through the flow meter (42).     The difference in volume be-tween the inhaled gas and the exhaled gas is proportional to the oxygen consumption of the subject and the micropro-cessor (20) integrates that sig-nal over the time of the test, and multiples it by a constant to provide a metabolic rate display. The temperature and water vapor content of the in-haled air are adjusted to that of the exhaled air either by passing both the inhaled and exhaled gases through the scrubber (30) before their volume is measured, or by preheating the inhaled air and employing a water absorbent member to add moisture to the inhaled air and remove it from the exhaled air.

Abstract: A centrifugal fan includes a housing that defines an air inlet leading to an air chamber defined within the fan impeller and an air exit port coupled to an air passageway. The housing includes a shroud that defines a two zone air passageway in the housing. The first zone, commencing adjacent to the base of the exhaust port, is a conformal portion that is conformal to the exterior diameter of the centrifugal fan and spaced slightly apart therefrom.  The second zone of the shroud is a scroll portion wherein the angle of expansion is capable of expanding between 10° and 15°.  An air restrictor plate is supported inside the air chamber of the centrifugal fan.  At ` the greatest width of the air restrictor plate, the air restrictor plate subtends an arc that is substantially coextensive with the arc subtended by the first conformal zone of the shroud.  The restrictor prevents the flow of inlet air through the centrifugal fan in the region of the conformal shroud.

Granted: 1999-09-28
Abstract: Establishing a multimedia telecommunication conference call with reduced bandwidth if not all participants are available to be part of the conference call by telecommunication terminals. When one telecommunication terminal is initiating a conference call, the initiating telecommunication terminal first establishes low speed data links with each of the other telecommunications terminals that are to be part of the conference. When all users of the other telecommunication terminals are ready for the conference, the other telecommunication terminals signal the initiating telecommunication terminal which then adds the necessary bandwidth to the conference call to establish the multimedia telecommunication conference call. Since the conference call is already set up, the initiating telecommunication terminal only has to add the necessary bandwidth to conference call. Each participant in the telecommunication conference call designates when they are ready to have the conference call start. In addition, each participant can choose not to take part in the conference call.

Abstract: A pear processing method and apparatus is provided which includes several mechanisms for properly orienting the pear prior to coring, peeling and seed celling of the pear.  Each pear is  tumbled between a pair of orienting rolls to a position wherein the stem of the pear is oriented downwardly. Whiskers  on one of the rolls speed up this orienting of the pear.  A friction clutch on the other roll helps maintain the pear in its proper position, once the proper alignment  has been attained.  The pear is dropped downwardly into a transfer cup having four resilient fingers which tend to orient the pear.  The pear is then pushed out of the transfer  cup downwardly  into a feed cup having a concave receptacle  for centering the stem of the pear and three upwardly  extending arms which grasp and center the blossom end of the pear.  The pear is then transferred to a station wherein the  pear is cored and thereafter peeled and seed celled simultaneously. The stem and blossom are also trimmed.  The pear is  thereafter passed into a slice cup having a design which more effectively separates the waste from the processed pear.
