Title: Resin impregnated composition
Inventor: MATSUO TOMOSHI
IPC: G01N31/22
Filed: 1991-12-24
Abstract: PURPOSE:To make remedy and to maintain stability by compounding an indicator making a coloration reaction with iron ions and an org. acid or its salt with the resin impregnated compsn. to be used for impregnation adhesion of cast iron, etc., thereby early knowing that the stability of the compsn. is lost. CONSTITUTION:The resin impregnated compsn. essentially consisting of (meth) acrylic ester and a polymn. initiator is gelatinized and thickened when the iron ions are incorporated thereon. The impregnation process is then not progressed any more. A metal ion capturing agent is, therefore, previously added to the compsn. to prevent the influence of the iron ions. The capturing agent needs to be replenished when the capturing agent is consumed as the amt. of the iron ions incorporated into the resin is too large. The indicator exhibiting the coloration reaction with the iron ions is previously compounded with the resin impregnated compsn. in order to early know whether the capturing agent is consumed or not. This consumption is known by the coloration. The org. acid. or its salt is added to the resin in order to assure the coloration reaction. The indicator is preferably compounded with 0.01 to 3wt.% mixture composed of 1:5 to 5:1 potassium ferricyanide: potassium ferrocyanide.

Abstract: PROBLEM TO BE SOLVED: To prevent a liquid drip phenomenon by setting a water film forming means to seal the upstream washing water in a passage with forming a water film in the state of crossing the passage at the time of stopping water on the passage for washing water including a washing water outlet in a water injection hole. SOLUTION: When a water supply cock is opened, washing water flows into an introduction pipe part 14 through its water intake pipe to be circulated in an internal passage 34 of a cylinder member 30. The washing water flows into an annular space 13a through an opening 38 to be injected from a water injection hole 28 to the inside of a urinal, thereby washing the inside of the urinal. When a water supply cock is closed, water injection from the water injection hole 28 is stopped. At this time, a water film is formed according to the surface tension of water at a part of a mesh 40 provided in the opening 38 of the forward end of the cylindrical member 30, whereby the washing water in the upstream part of the mesh 40 is sealed in the internal passage 34 and the inside of an intake piping. Accordingly, washing water remaining in the inside of the water supply pipe after stopping can be prevented from being dripped in the urinal, and the dirt of the urinal due to such liquid dripping can be prevented.
