Abstract: The method makes it possible to prevent deterioration of safe efficiency caused by malfunction of a compressor and eliminates unpleasant feeling caused by an excessive temperature difference between indoor and outdoor. Upon selecting a heating mode with a remote controller(100), a receiver(200a) of an indoor device(200) applies an optical signal according to the heating mode to a first micom(200c). Thus, the first micom(200c) reads data according to the heating mode and senses the indoor temperature through an indoor temperature sensor(200b). The first micom(200c) calculates a difference between a predetermined temperature entered from the remote controller and the sensed indoor temperature and drives an inverter compressor(300b) according to input data for heating operation. Thereafter, the first micom(200c) drives an internal timer to sense an elapse of time and performs a heating operation when a predetermined time is not elapsed.

A quenching operation is provided at the end of the process to embrittle the particles and before the particles are ground. The ground grit which is produced may then be sorted by size and used as an abrasive compound, or, alternatively may be further ground and annealed in a subsequent operation to provide suitable powder for forming sintered parts. Prior to annealing the grit may be further ground in a partial oxidizing atmosphere to preoxidize the powder, in order to provide oxygen directly within the powder to react with any residual carbon so that the carbon monoxide gas can be formed and the powder can be substantially free of both carbon and oxides when the reaction is complete. Alternatively, the powder may be preheated in a controlled atmosphere prior to annealing to preoxidize the powder.

Title: Composition containing buprenorphine and the use thereof for reducing heroine and alcohol consumption
Inventor: TICE THOMAS R
IPC: A61K47/14
Filed: 2000-08-25
Abstract: The invention relates to an injectable composition of partially opioid agonist or opioid antagonist, with sustained release, which contains a partially opioid agonist or antagonist in a poly(D,L-lactide) excipient with a small residual amount of ethyl acetate. After intramuscularly injecting the composition, the partially opioid agonist or the opioid antagonist is released in a controlled way over a period of time. The compositions may be used for treating heroin- and alcohol-addicted consummers in order to reduce the consumption of excessively used substances. For this purpose there may be administered: buprenorphine, methadone and naltrexone.
Patent RO-121516-B1 (RO)
Title: Machine for making recipients by blowing
IPC: B29C49/28
Filed: 2003-05-22
Abstract: The invention relates to a machine for making recipients by blowing, especially recipients made up of thermoplastics, such as polyethylene-terephthalate (PET) by processing some previously heated pieces. The machine for making recipients by blowing, by both axial and radial spatial deformation, for this purpose using previously heated pieces, consists of a fixed semi-die (22) and a mobile semi-die (23), the actuation being carried out by a knee mechanism, inside of the die cavities there being located the pieces characterized in that, the axial deformation is carried out by using some blowing pipes (34), provided at the lower side with a termination (35) and at the lower extremity with blowing orifices (a), at a low blowing pressure p1 with the value of 3-9 bar, the machine being also provided with a cross-beam (42) driven by a pneumatic cylinder (40), the cross-beam carrying two high pressure sealing-blowing heads (45) provided with joint packings (46) and the high pressure supplying nozzles (48) wherethrough there is introduced a high blowing pressure p2, with a value of 15 to 25 bar.
