The second mask defines a second interior space and is configured to be adjustably secured to the post and to form a substantial seal around the user's oral cavity when pressed against a portion of the user's mouth. The post is coupled to the oral appliance arch and is configured to adjustably secure the first mask relative to the oral appliance arch.

A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

The present invention relates to an improved process for preparing polyalkenylsuccinimides having a sediment level less than 0.1 vol % comprising the steps of:

    • (i) reacting a polyalkylene with an unsaturated acidic reagent in the absence of a strong acid until at least 25% of the polyalkylene is converted to a polyalkenyl derivative of an unsaturated acidic reagent;
    • (ii) continuing the reaction with an excess of the unsaturated acidic reagent in the presence of a strong acid to convert at least some of the unreacted polyalkylene to additional polyalkenyl derivative of an unsaturated acidic reagent; and
    • (iii) removing the unreacted unsaturated acidic reagent;
  • (b) reacting the unfiltered product of step (a) with a polyamine having at least one basic nitrogen atom;
  • (c) diluting the product of step (b); and

A two-stage switching power supply includes a first-stage power circuit, a second-stage power circuit, an output detecting circuit and a power control unit. The first-stage power circuit includes a first switching circuit. By conducting or shutting off the first switching circuit, an input voltage is converted into a bus voltage. The second-stage power circuit includes a second switching circuit. By conducting or shutting off the second switching circuit, the bus voltage is converted into an output voltage. The output detecting circuit generates an output detecting signal according to the output voltage. The power control unit controls operations of the first and second switching circuits according to the output detecting signal. A first-stage voltage gain value of the first-stage power circuit and a second-stage voltage gain value of the second-stage power circuit are altered with the output detecting signal, so that the output voltage is maintained at a rated value.

This invention relates to a method (and a corresponding system) of creating a cylinder oil, the method comprising modification of at least one initial fluid (101) by determining the TBN(s) of the at least one initial fluid, determining a desired TBN of a cylinder oil (102) and adjusting the TBN(s) of the at least one initial fluid (101) accordingly by blending the at least one initial fluid (101) with suited additive(s) (103). In this way, a method (and system) for modifying initial fluid(s) to create a cylinder oil by adjusting TBN is obtained. This provides significant economical benefits since lubricants that otherwise would have to be disposed of can be re-used as a total-loss cylinder lubricant. Further cylinder oil does not have to be purchased. The oil(s) used to blend the cylinder oil is/are of more consistent quality as it is replenished contrary to the traditional practice which reduces machinery wear, etc. Thus, the replenishment of the initial fluid(s) provides enhanced and consistent performance of the initial fluids resulting in greatly reduced component wear and equipment lifecycle cost. Even further, a more environmentally friendly method/system is provided since waste, in the form of spent oil(s) that is discarded after prolonged use, is reduced as it is converted into a cylinder oil.

An improved thin film PV module and simplified fabrication process are provided that achieve higher PV module efficiency, while eliminating expensive process steps, and reducing the capital cost of thin film processing equipment. A lamination material, characterized by high reflectivity as well as thermal conductivity and emissivity, is provided directly adjacent the active region of a thin film stack, eliminating the need for complex sputtering or deposition process steps ordinarily required for providing a reflective layer. The lamination material reflects unabsorbed light back into the thin film stack, thereby increasing photocurrent generation, and obviating the need for a reflective metallization layer. The lamination layer and back sheet for sealing the light-absorbing stack against the ingress of moisture also can be applied in a single process step.
