    摘要： A method and apparatus is provided for cleaning and rejuvenating septic tank sewage systems. Where the septic tank has a drainfield associated therewith, the method comprises penetrating the ground near a drainfield lateral, and agitating the area near the drainfield lateral while simultaneously applying suction to the drainfield lateral. Accumulated scum and waste is thereby removed from the drainfield lateral. Where the septic tank system has a dry well associated therewith, the method comprises penetrating the bottom of the dry well and agitating the area underneath the dry well to form accumulated scum and waste into a froth or malt at the bottom of the dry well, and removing the froth or malt by suction. The apparatus of the present invention comprises a penetrating nozzle attached to an articulated boom assembly for penetrating the ground near a drainfield lateral or underneath a dry well to apply forced air or fluid or suction to agitate the area near the drainfield lateral or underneath the dry well.

    摘要翻译： 提供一种清洁和恢复化粪池污水系统的方法和装置。 在化粪池具有与之相关联的排水场的情况下，该方法包括在排水区侧面附近穿透地面，并且在排水区侧面附近搅动区域，同时向排水区侧面施加吸力。 因此，积聚的浮渣和废物从排水区侧面移除。 在化粪池系统具有与之相关的干井的地方，该方法包括穿透干井的底部并搅动干井下面的区域，以形成积累的浮渣和废物进入干井底部的泡沫或麦芽，以及 通过抽吸去除泡沫或麦芽。 本发明的装置包括连接到铰接式起重臂组件上的穿透喷嘴，用于在干井的侧面或下方穿过排水区附近的地面，以施加强制空气或流体或抽吸来搅动干井外侧或下方的排水区附近的区域 。

    摘要： An improved IR radiation source is provided by the invention. A radiation filament has a textured surface produced by seeded ion bombardment of a metal foil which is cut to a serpentine shape and mounted in a windowed housing. Specific ion bombardment texturing techniques tune the surface to maximize emissions in the desired wavelength range and to limit emissions outside that narrow range, particularly at longer wavelengths. A combination of filament surface texture, thickness, material, shape and power circuit feedback control produce wavelength controlled and efficient radiation at much lower power requirements than devices of the prior art.
