Title: Apparatus and method for air drying with reduced oxygen enrichment
Inventor: SCHOOFS GREGORY R
IPC: B01D53/26
Filed: 1991-07-18
Abstract: APPARATUS AND METHOD FOR AIR DRYING   WITH REDUCED OXYGEN ENRICHMENT                    ABSTRACT OF THE DISCLOSURE Adsorbers used to dry air frequently contain 4A or 13X molecular sieve zeolites, which are intermittently reactivated by thermal regeneration.  When a thermally regenerated adsorber is repressurized, nitrogen adsorbs preferentially relative to oxygen in activated 4A and 13X molecular sieve zeolites.  This produces an oxygen-enriched, high pressure gas within the adsorber vessel which emerges immediately after the adsorber is brought on line.  The oxygen-enriched, high pressure gas can cause fires, explosions, and other deleterious effects in and downstream of such adsorber vessels.  This invention provides thermally regenerated air driers, adsorbent chambers and air drying processes using adsorbent compositions that do not adsorb nitrogen preferentially to oxygen.  Thermally regenerated air driers, adsorbers and drying processes using such adsorbent compositions prevent the problems associated with transient oxygen enrichment.

Title: Filling assembly for doll with liquid reservoir
Inventor: LAUER DANIEL J
IPC: A63H3/00
Filed: 1991-08-07
Abstract: DOLL Abstract of The Disclosure A newborn infant doll is disclosed which has a head, neck, arms, torso, and legs, and the body of the infant doll is realistic in feel, compressibility, and flexibility.  The infant doll includes a contiguous reservoir consisting of an empty cavity formed in the neck, the torso, the legs, and the arms of the infant doll.  The reservoir is capable of being filled with a liquid medium, such that when the reservoir is filled, hydraulic interactive force is created from the neck down of the infant doll.  The doll neck can simulate the weakness of a newborn infant's neck.  The infant doll further includes a filling mechanism which allows the reservoir to be filled with the liquid medium, and further prevents the liquid medium from spilling out of the reservoir.  Temperatures simulating that of living infants can be created by filling the reservoir with water at selected temperatures.

Title: Rotary heat exchanger of improved effectiveness
Inventor: PRAVDA MILTON F
IPC: F28D19/00
Filed: 1991-09-27
Abstract: ABSTRACT OF THE DISCLOSURE      A Perkins tube type rotary heat exchanger of improved efficiency wherein the Perkins tube evaporation sections are outwardly  displaced  from  the  condensation  sections  by offsetting and/or  splaying,  to  substantially  occupy  the evaporation sections with Perkins tube working fluid while substantially eliminating the presence of fluid from a major portion of the condensation sections during operation of the heat exchanger.   This has the effect of maximizing the internal evaporative area within the evaporation sections and also of maximizing the internal condensing area within the condensation sections of the Perkins tubes, thereby materially increasing the energy recovery and effectiveness of the heat exchanger.

Abstract: En plongée sous-marine, le plongeur porte une veste gonflable qui lui permet de contrôler sa flottaison. La présente invention est une veste à deux compartiments. Lorsque les compartiments sont vides, la masse volumique du plongeur est supérieure à celle de l'eau et il coule vers le fond. Quand les compartiments sont gonfles, la masse volumique du plongeur est inférieure à celle de l'eau et il flotte vers la surface. Si seule le premier compartiment est plein d'air, la masse volumique du plongeur est égale à celle de l'eau et il reste en suspension. Par l'automatisation du compensateur de flottaison, le plongeur n'a plus besoin d'ajuster manuellement sa flottaison et peut porter son attention vers son environnement. En facilitant ainsi le contrôle de la flottation, la plongée est plus agréable et plus sécuritaire.

Title: Container scale
Inventor: WIRTH JOHANNES
IPC: B65F3/02
Filed: 1991-12-05
Abstract: The present invention concerns a process and a device for carrying out the process for weight determination of the contents of containers (5), for example for garbage.  Two swivel arms (2) that are lifted by hydraulic devices (3) are mounted on a garbage collecting vehicle (1).  The container (5) is carried by a fork (4).  Integrated into the swivel arm (2) is a force measuring apparatus that comprises two flexural members (7) supporting the main load, two spring tongues (8), and a force transducer (11) that is installed between two stilts (12) between the spring tongues (8).  The flexural members (7) and the spring tongues together form an elastic stepdown; the force transducer (11) thus only measures that part of the total load flowing through it as given by the stepdown. Further, a gradient meter (16) is mounted on the swivel arm (2), that has the same action line W as the force measurement device integrated in the swivel arm (2).  In this manner, the measurement of the weight of the container (5) is very extensively independent of the gradient. The weight of of container (5) is calculated in known manner by two "total weight - tare = net" weighings.  In order to exclude the influences of elastic prestresses, the angle range over which it is measured is limited to a preset degree.  The container (5) is inserted in the fork (4) in the position ?, position ? is the measuring position, and the container (5) is emptied in position ? (Figure 1).
