摘要： Conventional SCUBA diving equipment is heavy and cumbersome, mainly due to the mass and size of the breathing gas carrier, i.e. the pressure vessel. A preferred pressure vessel for SCUBA diving can be as light as possible and neutrally buoyant at all stages of the dive. To achieve such preferred characteristics, the pressure vessel volume can be adjusted in accordance with the change in its mass. The present invention provides SCUBA systems that provides for the preferred characteristics.

摘要： El equipo de inmersión de BUCEO convencional es pesado y engorroso, debido principalmente a la masa y el tamaño del portador de gas respirable, es decir, el recipiente a presión. Un recipiente a presión preferido para la inmersión de BUCEO puede ser lo más ligero posible y flotante de manera neutral en todas las etapas de la inmersión. Para lograr tales características preferidas, el volumen del recipiente a presión se puede ajustar de acuerdo con el cambio en su masa. La presente invención proporciona sistemas de BUCEO que proporcionan las características preferidas.

摘要： The present invention describes methods and apparatuses for the synthesis of 5-(chloromethyl)-2-furaldehyde (CMF) from saccharides in pure or crude form, the method comprising: (a) continuously contacting saccharides in pure or crude form, hydrochloric acid, and an organic solvent, by way of a continuous, biphasic-flow reactor assembly at a temperature from about 60 degrees C. to about 200 degrees C. and pressures from about 1 atmosphere to about 20 atmospheres, such that CMF is produced; (b) separating 5-(chloromethyl)-2-furaldehyde by liquid/liquid and solid/liquid phase separation; (c) producing at least five kilograms per day with at least 50% yield. Embodiments of the present invention can produce CMF in a continuous fashion, with high yield and without degradation of CMF to such side products as 5-(hydroxymethyl)furfural (HMF), 2-(2-hydroxyacetyl)furan (HAF) and levulinic acid (LA).

摘要： SCUBA diving equipment is composed of a heavy SCUBA pressure vessel, buoyancy compensation device and a heavy weight system. Together with a constricting exposure suit the current setup makes for a rather cumbersome system. Perfect buoyancy is a term used in SCUBA diving to describe the ability of the diver to maintain its vertical position in the water column. Doing so requires a thorough understanding of the governing physics principles as well as considerable practice time. Together, the cumbersome nature of standard SCUBA systems and the physical and mental requirements of operating said systems underwater are a commercial hurdle, preventing many individuals from entering the sport. The present invention provides systems that can significantly simplify both elements by allowing water to occupy some of the pressure vessel internal volume. Such a pressure vessel can be used as both the breathing gas source as well as a buoyancy control device, reducing or even eliminating the need for additional weights and a separate buoyancy compensation device. Embodiments of the present invention also comprise a control system and one or more sensors to provide an automatic buoyancy system.
