Title: Pipe coupling
Inventor: ZEIDLER SIEGMUND
IPC: F16L21/06
Filed: 1988-03-31
Granted: 1991-11-19
Abstract: ABSTRACT         The non-profiled end portions of two pipes can be coupled to each other by a ring-shaped band which has at least one axially parallel gap and circumferentially extending corrugations defining two outer chambers and at least one median chamber.  Each chamber is open toward the peripheries of the pipes and each outer chamber surrounds a different pipe. Such outer chambers contain arcuate safety devices with radially innermost portions in the form of claws serving to penetrate into the material of the respective pipes when the band is tightened around the end portions of the pipes by a clamping unit which is designed to reduce the width of the gap. The median chamber of the band confines a deformable annular insert which has marginal sealing lips and serves to establish a seal between the internal surface of the band and the peripheral surfaces of end portions of the pipes when the clamping unit is actuated to reduce the diameter of the band.  Each safety device includes several arcuate sections which are connected to each other and whose median portions can be movably secured to the adjacent portions of the corresponding outermost corrugations of the band.

Title: Radio wave leakage diagnosing system for intelligent building
Inventor: TAKAHASHI TAKESHI
IPC: G01R23/00
Filed: 1988-05-18
Granted: 1991-09-10
Abstract: ABSTRACT    Disclosed is a radio wave leakage diagnosing system for use in an intelligent building which is constructed using an electromagnetic shielding material for the skeleton and openings such as windows and doorways so that the whole of the building is formed into an electromagnetic shielding structure.  The system has radio wave detecting means disposed outside the building for detecting a predetermined radio wave transmitted from each floor of the building, so that a floor, together with a specific position, where there is a leakage of radio wave is detected on the basis of the intensity of the detected radio wave.  With this arrangement, a predetermined radio wave is transmitted from each floor of the building and the transmitted radio wave is detected by the radio wave detecting means.  Accordingly, the degree at which the radio wave leaks from each floor can be checked on the basis of the intensity of the received radio wave, and when the electromagnetic shielding is broken, the floor and specific position where the shielding abnormality occurs can be found on the basis of the intensity of the received radio wave.  When the electromagnetic shielding performance has deteriorated, it is possible to know the degree of deterioration by making a comparison with the diagnostic result  obtained in the past.
