摘要： A pre-smoke detector and system for use in early detection of developing fires whereby vapors of marker chemicals generated during the melting and/or smoldering of common household materials are detected before detection by conventional smoke detectors. Vapors resulting from heating and resultant vaporization of substances are detected as well as vapors resulting from their breakdown, decomposition, or pyrolysis during the pre-combustion stage. Conventional smoke detectors focus on particle detection and are most effective after a developing fire has produced smoke. To minimize false alarms caused by common household odors, the pre-smoke detectors focus on detecting medium temperature pyrolysis products using sensor coatings that can be consistent with a 10 year operational lifetime and multiple orthogonal detection processes. Since virtually all marker chemicals of interest for pre-smoke detection are heavier than air, a system is described that appropriately integrates with smoke detector alarm systems present in most homes.
摘要翻译： 用于早期检测发展中火灾的烟雾前检测器和系统，其中在常规烟雾探测器检测之前检测到在普通家用材料的熔化和/或阴燃期间产生的标记化学品的蒸气。 检测由物质的加热和所得蒸发产生的蒸气以及在预燃烧阶段由它们分解，分解或热解产生的蒸气。 传统的烟雾探测器专注于颗粒检测，并且在发生火灾产生烟雾之后是最有效的。 为了尽量减少普通家庭臭味引起的假警报，烟雾探测器集中在使用传感器涂层检测中温热解产物，这可以与10年的使用寿命和多个正交检测过程保持一致。 由于几乎所有用于预烟雾检测的标记物质都比空气重，所以描述了适合与多数家庭中存在的烟雾探测器报警系统集成的系统。

摘要： The aim of the invention is to provide a commercially usable and inexpensive device and method with which a sorption enthalpy can be measured in a simple manner. This is achieved by a device for calorimetrically measuring sorption processes, comprising a sorption cell for receiving a sample, the sorption cell having a volume for filling with a sorption gas, and comprising a reference cell likewise for filing with the sorption gas. A measurement gas volume is arranged around the sorption cell for receiving a reference gas, and the reference cell is surrounded by a reference gas volume, which is likewise provided for receiving the reference gas. A gas connection is provided between the sorption cell and the reference cell in order to conduct sorption gas into the sorption cell and the reference cell such that a sorption reaction occurs with the sample in the sorption cell. Furthermore, a device is provided for measuring pressure differences between the measurement gas volume and the reference gas volume in order to carry out a calorimetric measurement of the sorption process on the sample in the sorption cell on the basis of a volume change of the reference gas in the measurement gas volume.

摘要： Triglyceride oils having one or more populations of asymmetric triglyceride molecules are provided. Asymmetric triglyceride molecule populations are triglyceride molecules that consist of a C8:0 fatty acid or a C10:0 fatty acid at the sn-1 position and the sn-2 position, and C16:0 or C18:0 at the sn-3 position. Another population of asymmetric triglyceride molecules are triglyceride molecules that consist of a C16:0 fatty acid or a C18:0 fatty acid at the sn-1 position and the sn-2 position, and C8:0 or C10:0 fatty acid at the sn-3 position. Methods of producing triglyceride oils and using the same are provided using sucrose invertase and hydrogenation of the triglyceride oil. Triglyceride molecules are produced by using recombinant DNA techniques to produce oleaginous recombinant cells.
