Abstract: A process for humidifying a gas stream in a humidifier chamber by passing heated water downwardly through the humidifier and passing gas upwardly through the chamber to transfer water vapor to the gas stream. One or more portions of the water is removed at an intermediate stage in the chamber and the remaining portion of the water collected at the bottom is removed. The intermediate portion and final portion may have make-up water added thereto and the portions are reheated either separately or as a combined mixture. The process provides an improved economic method for humidification with good energy savings.

Abstract: The invention relates to a device in a machine for trimming vegetables, especially Brussels sprouts, by means of a rotary cutter forming the bottom of a trapezoidal groove (3), which is formed by the inclined sides (2) of a pair of rotary flanges, the vegetables being caused by the action of the rotary flanges and stationary holding means (5-12) to perform a rotary movement around themselves at the same time as they follow the rotary flanges in the groove (3) between them, and projecting parts of the vegetables are exposed to the cutter and trimmed off. According to the invention the holding means consists of a number of substantially planar plates (5-12), which are arranged resiliently and elastically pivotable around axes (13-20), which are substantially parallel to the rotary shaft of the cutter and of the flanges, which overlap each other like roof tiles substantially along the groove (3) between the flanges with the free ends of the plates pointing in the direction of rotation, and which form a ceiling of the groove along a part thereof (FIG. 1).

IPC: C10G35/12
Filed: 1986-12-22
Abstract: Regeneration of a spent hydrocarbon conversion catalyst is accomplished by means of a moving bed of catalyst, where catalyst is passed through several treatment zones, in a unique regeneration vessel. The catalyst is first contacted with a hot oxygen-containing gas stream in a burning zone in order to remove coke. The catalyst is then passed into a drying zone for removal of water formed in the combustion zone by passing a hot dry air stream through the catalyst. This hot air stream is produced by exchange of heat with catalyst, thereby effecting cooling of the regenerated catalyst and by use of an air heating means located in the vessel. After passing through the drying zone, the air stream provides oxygen for combustion in the combustion zone.

IPC: G01N27/72
Filed: 1989-10-02
Granted: 1995-03-14
Abstract: Oxygen sensing apparatus and methods utilize a sensing cell including two pairs of electrically heated thermistors and a source of an inhomogeneous magnetic field.  One thermistor of each pair is positioned inside the magnetic field, and the second thermistor of each pair is positioned adjacent to the respective first thermistor of each pair, substantially outside the magnetic field.  When oxygen is present in the sensing cell, the thermistors inside the magnetic field generate a gas flow in the direction of the adjacent thermistors of each pair positioned outside the magnetic field, thus tending to reduce the temperature of the thermistors inside the field and increase the temperature of the thermistors outside the field.  The thermistors are connected in a measuring bridge circuit including elements for maintaining the temperature of the thermistors at a substantially constant level, thereby providing a signal that can be used to compensate for changes in the thermal characteristics of the background gases.

Filed: 1990-04-26
Granted: 1994-11-08
Abstract: An air detector according to the present invention utilizes a unitary type sensor for detecting air bubbles or columns  in an infusion solution flowing through a tube. Because of a unique design for a tube-receiving groove and a cooperating abutting member, the difficulty in loading a tube heretofore encountered with the use of unitary type sensor is avoided.  Thus, the tube can be loaded in the air detector easily with good reliability.

Title: Preemptive demount in an automated storage library
Inventor: HARTUNG JOSEPH CHARLES
IPC: G06F3/06
Filed: 1991-03-28
Granted: 1995-08-29
Abstract: A method for selecting data storage media for demount in an automated storage library,  and an automated storage library  and  program  product  therefor  are  disclosed. Preemptive demount of storage media is permitted when all peripheral storage devices in the library are occupied and one or more of such devices remains inactive for a predetermined time.   Storage media may be demounted to service existing mount requests, provided the peripheral storage  devices  in  which  the  media  are  mounted  are inactive.  There is also a need, however, to ensure the availability of an empty device to service future mount requests, particularly in libraries having only a single gripper mechanism. Thus, even when no mount requests are pending, the status of the peripheral storage devices is continually monitored.  If the peripheral storage devices are all occupied, and one or more of such devices remains inactive for the predetermined time, the least recently used storage medium is demounted and transferred to a storage cell in the library.

Title: Line scanning apparatus using staggered linear segments with adjoining overlap regions
Inventor: ERHARDT HERBERT J

Granted: 1995-07-25
Abstract: A linear sensor (30) composed of substantially like-sized segments (40a, 40b, 40c, 40d) generates a high definition television signal from a line scan of a motion picture film (12).  By staggering the linear segments and overlapping adjoining ends (41) thereof, the sampled signal outputs of the several segments can be applied to a series of digital filters (78, 80, 82, 84) that operate independently to provide filtered output signals that can be grouped together without processing artifacts at the crossover points.  More particularly, the overlapping regions (41) of the linear segments are configured in relation to the processing kernal required by the digital filters such that contiguous, processed samples on either side of each crossover point (c) are derived from sample strings wholly within a respective linear segment.

Title: Barrel clamp
Inventor: ROULEAU GILLES
IPC: B66C1/62
Filed: 1991-05-15
Granted: 1995-06-20
Abstract: There is disclosed a lifting device particularly suited for lifting plastic drums or barrels while maintaining the same vertically upright and transporting the same to another location.          The lifting device is unique in that it employs a locking bar which is capable of locking the device in both the open position preparatory for securing the barrel, and the grasping/lifting position.  It maintains either of these locked positions regardless of whether an upward force is exerted upon the pair of pivotal tongs.  Unlike other pivoted lifting devices or tongs, the present invention uses a minimal amount of friction force to lift a barrel, such that the fragile resilient sides of a plastic barrel are not damaged.
