Title: Refrigerant recovery system
Inventor: RICKETTS WILLIAM H
IPC: F25B45/00
Filed: 1993-05-26
Abstract: ABSTRACT           A circuit for recovering refrigerant from a disabled refrigeration unit combines a vacuum pump, vapor pump or compressor in series with a compressor for drawing gaseous refrigerant from the disabled unit.  The series arrangement of the vacuum source and the compressor provides approximately -29 inches of mercury at the suction side of the vacuum source. A condenser in series with the compressor converts the gaseous refrigerant into a liquid refrigerant and a storage tank in series with the condenser receives liquid refrigerant from the condenser.  In one preferred arrangement a valve system connected in series between the condenser and the storage tank allows the storage tank to be disconnected from the circuit without release of refrigerant from the tank to the atmosphere.  The circuit may also include a coil in parallel with the condenser and the compressor and helically disposed around the storage tank for cooling the storage tank.  A separator may be connected in series between the vacuum source and the compressor for removing impurities from the gaseous refrigerant and another coil connected in series between the compressor and the condenser and helically disposed around the separator may be used to heat the separator.  In addition to the gaseous refrigerant recovery line, a liquid refrigerant line in series between the unit and the storage tank drains liquid refrigerant from the unit into the storage tank prior to operation of the gaseous refrigerant recovery line.

Abstract: ABSTRACT OF DISCLOSURE       The present invention discloses a system for protecting copyright  of  a  software  to  be  supplied  to  a  compound communication terminal device including a communication unit and an information processing unit; further for automatically starting a program depending where the compound communication terminal device locates.       A protection key to protect the copyright is generated in accordance with communication information relating to the compound communication terminal device and it is embedded into the software together with a detection unit.       The compound communication terminal device holds  a correspondence  table  indicating  correspondence  between notification information received from a base station and a program  to  start,  and  a  start  unit  for  receiving  the notification information and starting a program corresponding to the received notification information in the correspondence table.   Accordingly, a program to start can be selected in accordance with location of the compound communication terminal device.  Validation of operation of a software is determined as referring to validation of a source number or a destination number over the communication network and user registration information.  Data and a part of a program are taken from the software beforehand, so that operation of the software cannot complete itself unless transmission request from the compound communication terminal device is validated and receives the missing data and the missing part of a program.

Abstract: Grâce à l'invention du CHARIOT POUR TAILLE-HAIES dont il sera ici question, il est possible de tailler mécaniquement une haie ou un arbuste, avec un taille-haies ordinaire, sans recourir aux services de professionnels. Il s'agit en l'occurance d'une méthode inédite qui consiste à a) adapter un taille-haies de façon qu'il puisse être fixé à un CHARIOT POUR TAILLE-HAIES et b) faire rouler le chariot sur une "voie métallique" ins tallée au-dessus du sol, le long de la haie ou autour de l'arbuste. MEMOIRE DESCRIPTIF CHAMP D'APPLICATION La présente invention se rapporte à une méthode inédite de tailler les haies et les arbustes; selon cette méthode et, grâce à une installation appropriée incluant le CHARIOT POUR TAILIEHAIES, il est possible de tailler des haies et des arbustes de toutes formes, de toutes dimensions raisonnables (entre 2 et 12 pieds) et de toutes les essences (conifères ou autres) qu'un taille-haies coupe normalement. La seule restriction à l'énoncé qui précède concerne les haies qui sont courbées et qui exigeraient une "voie métallique" tellement irrégulière qu'elle ne serait pas pratique. BUTS DE L'INVENTION Le but premier de l'invention est de permettre aux propriétaires de tailler eux-mêmes leurs haies et arbustes, Plusieurs sont empêchés de le faire pour différentes raisons: 1- Ils ont peur de "tailler tout croche"; c'est là la prin cipale caractéristique du CHARIOT POUR TAILLE-HAIES: il permet une coupe égale et constante. 2-
