Title: Method of initiating the premature replacement of a roll of material
Inventor: JUEHE HANS-HELMUT

Filed: 1995-04-07
Granted: 2000-06-20
Abstract: A process for initiating a premature roll change of a web to be unwound from a spool, the process including the steps of measuring temperature at an end of the spool in a zone up to 150 mm away from a surface of the spool in a radial direction during a time that the roll has between 100% and 60% of its fully wound weight, using a non-contact measuring device, determining a radial distance from the spool surface when a temperature difference 0.5 .degree.C is found between temperature measurement locations in the zone and cooler adjacent areas, and storing the determined distance for triggering a signal that initiates a replacement of the roll when that distance is reached.

Abstract: The present invention relates to a fastener and clip for use in attaching a button to a garment or a piece of fabric. In one embodiment, the fastener (11) comprises a U-shaped flexible filament (13) and a pair of transverse feet (15-1, 15-2) disposed at opposite ends of the U-shaped flexible filament (13). The U-shaped filament (13) is generally rectangular in cross section, has a substantially uniform width, a thickness greatest in its arcuate region and least towards the feet. The feet (15-1, 15-2) are sized and shaped to fit through a button hole and securely engage a garment. To minimize contact with a person's skin, the feet (15-1, 15-2) are preferably shorter that the transverse bars of existing button fasteners and comparable in overall size to a knot of thread conventionnally used to secure buttons. The feet (15-1, 15-2) have rounded ends (21-1/21-2, 23-1/23-2), a flat top surface (19-1, 19-2) and a contoured bottom surface (25-1, 25-2) to minimize irradiation of a person's skin.

Abstract: La présente invention concerne une thérapie génique ciblée mettant en oeuvre des vecteurs recombinants, en l'occurrence des vecteurs adénoviraux. L'invention concerne plus particulièrement des vecteurs fonction du mode de réplication ainsi que des procédés permettant de les utiliser. De tels vecteurs sont capables d'une réplication sélective dans un tissu cible apportant ainsi une amélioration thérapeutique imputable au vecteur en tant que tel ou imputable aux produits géniques hétérologues exprimés depuis le vecteur et se distribuant à travers le tissu. Dans ce type de vecteurs, un gène essentiel du processus de réplication est régi par une séquence de régulation de la transcription spécifique d'un tissu hétérologue. Il en résulte que la réplication est conditionnée par la présence d'un ou plusieurs facteurs induisant la transcription ou par l'absence d'un ou plusieurs facteurs bloquant la transcription de ce gène en raison de la séquence de régulation de la transcription accompagnant ce vecteur. Cette spécificité permet de traiter de façon sélective un tissu cible.

Abstract: Stored thermal energy absorbed by a working fluid (22) from hot thermal-energy-storage material (16) energies an open-Brayton-cycle automotive power-generation unit (10).      Sealed ceramic tubes (28), filled with a material that melts within thermal-energy-storage material's operating temperature range provides thermal energy storage. A rotary impeller (36) draws the flow of working-fluid (22) into the unit's compressor (32) from the surrounding atmosphere for discharge into a heat regenerator (56).      The regenerator (56) warms working fluid (22) using thermal energy extracted from hot turbine exhaust that is then discharged into the atmosphere.      Working-fluid (22) from the compressor (32) flows from the regenerator (56) through a heating vessel (12) into the turbine (76). The unit (10) includes an alternator (102) which generates electricity for powering an automobile's electric drive motors (194). Stored thermal energy may be regenerated either by a combustible-fuel burner (174) and/or an electrical heated (112) located within the heating vessel, or by an automated regeneration station (124).

Title: Air flow system for refrigerator freezer compartment
Inventor: TUNZI SCOTT T
IPC: F25D17/06
Filed: 1998-05-22
Granted: 2004-08-10
Abstract: An air flow system for the freezer compartment of a refrigerator includes air inlets located at an upper rear portion of the freezer compartment which direct a supply of cooling air forward and against both top and side walls of the compartment. The air then flows along an upper portion of the compartment toward a front thereof where it is redirected downward and rearward. The bottom wall of the freezer compartment is provided with a plurality of upstanding, laterally spaced ribs upon which food items can be supported.      Since the ribs are spaced, numerous channels are formed which extend from the front portion of the compartment to adjacent the rear wall. A gap is preferably created between the rear wall and the ends of the ribs such that air is permitted to flow laterally along a lower rear portion of the compartment. Air outlets or returns are also provided in the lower rear portion of the compartment for recycling of the air. With this arrangement, an effectively distributed and enhanced circulating flow of cooling air is created to efficiently maintain stored food items at a desired temperature.
