Title: Systeme de conditionnement d'air pour faible refroidissement ambiant
Inventor: SHAH RAJENDRA K
IPC: G05D23/12
Filed: 2007-01-22
Granted: 2013-12-24
Abstract: La présente invention concerne un système de conditionnement d~air comprenant un régulateur en liaison électrique avec un compresseur, un ventilateur de condenseur, un capteur de température qui mesure la température de l~air ambiant, un capteur de température qui mesure la température d~un serpentin de condenseur du système de conditionnement d~air, et un commutateur basse pression qui mesure la pression d~un frigorigène contenu dans le système. Un algorithme résident du régulateur commande le passage de ce dernier dans un mode de faible refroidissement ambiant lorsque la température de l~air ambiant est inférieure à une valeur fixée. L~algorithme commande également le régulateur pour imposer une fréquence de cycle de fonctionnement minimale et/ou maximale au ventilateur de condenseur. L~algorithme commande enfin le régulateur afin qu~il ne réagisse pas à un déclenchement du commutateur basse pression pendant la phase initiale d~un cycle de refroidissement dans des conditions de température extérieure basse, ce qui risquerait de ne pas indiquer correctement un incident du système, mais arrête néanmoins le compresseur suite à un déclenchement dans des conditions indiquant réellement un incident.

Abstract: A composite barrel for a firearm and method for forming by forging. The barrel includes at least two materials joined together by forging. In a preferred embodiment, at least one material is preferably lighter in weight than the other material. The barrel may include an inner tube and an outer sleeve. The inner tube defines a bore that provides a bullet path and in one embodiment may be made of steel or alloys thereof. The outer sleeve surrounds the inner tube and in some embodiments may be made of aluminum, titanium, or alloys of either thereof. The tube preferably includes an exterior surface containing recessed areas therein for receiving material displaced from the outer sleeve by the forging process. The preferred barrel forming method generally may include inserting the tube into the sleeve, striking an outer surface of the sleeve, and deforming the sleeve to force material to flow into the recessed exterior surface of the tube to bond the tube and sleeve together. The method of forming may be used to produce long and short barrels for rifles and handguns respectively, and more broadly to produce other composite components unrelated to firearms.

Abstract: Disclosed is a system and a method for providing a Visual ARS (VARS) service by using a call control function of a mobile communication terminal. In the system and the method, a user of a terminal can select an existing voice guidance service or an available visual guidance service when trying a call connection to a telephone number of an existing call center. When selecting a visual guidance service, an originator receives an ARS service on a screen of the terminal of the originator. Accordingly, the user can receive and use the VARS service according to the user's selection by using a mobile communication network, so that the user can handle a task requested on a screen of the terminal. Hence, it is possible to overcome the disadvantage of a limited voice guidance-centered ARS service that a call center currently provides in a stereotyped manner regardless of the generation development of terminals. Also, it is possible to provide various VARS services with the development of mobile communication terminals.
