摘要： A pair of hollow elongated leg sections are disposed in one or more of the nozzle vane cavities of a nozzle stage of a gas turbine. Each leg section has an outer wall portion with apertures for impingement-cooling of nozzle wall portions in registration with the outer wall portions. The leg sections may be installed into the cavity separately and support rods support and maintain the leg sections in spaced relation, whereby the designed impingement gap between the outer wall portions of the leg sections and the nozzle wall portions is achieved. The support rods are secured to the inner wall portions of the leg sections by welding or brazing.

摘要： An accessory filter for enhancing the operation of a HVAC panel filter, the HVAC panel filter having a peripheral frame that is receivable in a filter mount of a forced air HVAC system. The accessory filter includes a filter sheet having planar dimensions matching the frame; and adhesive attached near the edges of the filter sheet operable to adhere the filter sheet to the frame. The filter sheet has a thickness substantially thinner than that of the HVAC panel filter. The filter sheet thickness allows the HVAC panel filter and the accessory filter to coextensively fit in the filter mount.

摘要翻译： 一种用于增强HVAC面板过滤器的操作的附件过滤器，HVAC面板过滤器具有可接收在强制空气HVAC系统的过滤器支架中的外围框架。 附件过滤器包括具有与框架匹配的平面尺寸的过滤片; 并且附着在过滤片边缘附近的粘合剂可操作以将过滤片粘附到框架上。 过滤片的厚度基本上比HVAC面板过滤器薄。 过滤板厚度允许HVAC面板过滤器和附件过滤器共同安装在过滤器支架中。
