Refrigeration fluid compositions for refrigeration and air-conditioning circuits include a usual refrigerant fluid together with a liquid, hydrolyzable organosilane which remains in the liquid phase throughout the air-conditioning circuit, and which is capable of removing moisture from the interior of the circuit and sealing leaks.
摘要:
Leaks in a vessel or pipeline or the like adapted for containing a fluid, are sealed by means of a volatilized polymerizable aminosilane supplied to the interior of the vessel under sufficient pressure and for a sufficient period of time to permit contact thereof and react in the presence of moisture or sand at the situs of the leak to provide a solid polysiloxane seal.

Refrigeration fluid compositions for refrigeration and air-conditioning circuits include a usual refrigerant fluid together with a liquid, hydrolyzable organosilane which exists as a liquid in the liquid phase of the air conditioning or refrigeration circuit, and which is capable of removing moisture from the interior of the circuit without forming a solid upon hydrolyzation.
摘要:
Leaks in a vessel or pipeline or the like, adapted for containing a fluid, are sealed by means of a volatilized polymerizable organosilane comprising a mercaptosilane, an acyloxysilane, or an alkoxysilane taken on conjunction either with acetic acid anhydride or an amine, or mixtures thereof, the organosilane being supplied to the interior of the vessel or pipeline under sufficient pressure and for a sufficient period of time to permit contact and chemical reaction thereof in the presence of moisture or sand at the situs of the leak to provide a solid polysiloxane seal.

The jukebox for casino gaming machines provides a casino gaming machine that has at least one device for playback of audio, and may include a video display for playback of multimedia files. A separate central server in operable communication with a gaming machine client has access to player account information, as well as music, graphics and themes. The client communicates with a jukebox player. The jukebox player accepts and responds to user commands via a user interface. Earphones and earphone plugs are provided. The earphones and plugs host a debit/credit and player tracking system. The earphones and plugs communicate with an enabling device in the casino to allow a user to experience a selected entertainment program in its entirety while the user is operating the gaming machine.

A hollow capillary tube or cartridge is received within the interior of a hollow tubular syringe-like device to collect a blood sample. A fluid inlet means of the capillary cartridge connects in a fluid conductive relationship with a hypodermic needle attached to the syringe-like device to conduct a blood sample to the interior of the capillary cartridge. A fluid outlet means of the capillary cartridge allows the blood sample to fill the capillary cartridge by expelling air from the interior of capillary cartridge. The fluid outlet means includes a removable piece of fluid conductive fibrous material which allows the air to escape as the blood sample is received and which conducts a small amount of blood sample when the capillary cartridge is completely filled. Means for creating a pressure less than ambient pressure at the fluid outlet means of the capillary cartridge may be employed when the arterial blood pressure of the individual from whom the blood sample is collected is less than sufficient to naturally fill the interior of the capillary cartridge. Crystalline heparin deposited on the interior of the capillary tube prevents clotting of the collected blood sample.
