Title: Method of and device for removing volatile contaminants from the soil
IPC: E21B43/00
Filed: 1988-08-06
Granted: 1993-05-12
Abstract: Driving of volatile impurities from a ground by mans of air is performed by aspirating an afterflow air and impurities containing gases which penetrated through a permeable wall of a shaft in a ground, at one or several locations in regions of expected high gas contents, air afterflow passages are extended to these regions for supplying the afterflow air, and an adjustable afterflow resistance is arranged in the passages for influencing a negative pressure value and a flow speed in these regions.

Abstract: The invention proposes a multicomponent hot-melt adhesive, in contrast to a known polyurethane hot-melt adhesive which crosslinks in the presence of moisture and consists of a single reactive component which crosslinks in an uncontrollable manner in the presence of moisture after cooling. The hot-melt adhesive described consists of at least two components which react with each other. The remaining chemical crosslinking therefore occurs in a controllable manner and does not depend on the fortuitous presence of moisture.

Abstract: The operation sensor of a steam trap is used for judging the operating condition of a steam trap used in various installations using a steam and consists of an oscillation detection portion (1) and an operation processing portion (50) for operation processing the signals detected by the oscillation detection portion and outputting the results. The detection portion (1) includes a detection needle (2) brought into contact with an object of detection at a predetermined pressure urged by a flexible member and detecting mechanical oscillation of the detection object resulting from the steam flow and condensation flow in the object, an oscillation plate (21) for generating ultrasonic oscillation by the mechanical oscillation detected by the detection needle (2), an oscillation sensor (16) disposed so as to oppose the oscillation plate (21) and converting the ultrasonic oscillation to an electrical signal and a circuit substrate (20) including an amplification circuit for suitably amplifying the output from the oscillation sensor (16) and transmitting it to the outside. The operation processing portion (50) includes memory (M) for storing data corresponding to steam traps of various types inclusive of the detection object, a central processing unit (CPU) for performing operation by comparing the output of the detection portion transmitted from the detection portion (1) with predetermined data obtained selectively from the stored data of memory (M) and output portions (D; S) for displaying the result of operation by the central processing unit (CPU) and/or generating an audible output with an audio frequency. The operation sensor includes a temperature sensor (10) added to the tip of the detection needle (2) of the detection portion and can detect the temperature and/or steam pressure of the detection object. Accordingly, the operating condition of the steam trap can be judged more accurately.
