Title: Explosive charge operated tool for fastening elements
Inventor: GASSNER THEO
IPC: B25C1/18
Filed: 1987-03-11
Granted: 1992-02-20
Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.

Abstract: Regenerated adsorbent particles, such as activated carbon, are recovered from a wet oxidation-regenerated mixed sludge liquor from a wastewater treatment system by diluting and settling a blowdown slurry (20) from the wet oxidation reactor (12) to obtain a first aqueous phase (32) containing primarily regenerated adsorbent particles and fine ash particles and a first solids phase (28) containing primarily grit particles. The first aqueous phase (32) is combined with a portion (16) of the regenerated adsorbent particle slurry withdrawn from the upper portion of the wet oxidation reactor (12) and, after treatment with a dispersing agent (36) and then an anionic flocculating agent (44), the resulting mixture (46) is settled to obtain a second aqueous phase (54) containing primarily fine ash particles and a second solids phase (50) containing primarily regenerated adsorbent particles. The second solids phase (50) is recycled to the wastewater treatment system for re-use and, after treatment with a cationic flocculating agent (58), the second aqueous phase (54) is settled to obtain a substantially particle-free third aqueous phase (66) and a third solids phase (64) containing primarily fine ash particles. Slurries (28) and (64) containing the grit and fine ash particles are combined and dewatered prior to disposal.

Abstract: 본 발명은 접속이 이루어짐에 따라 전선의 둘레에서 압축되는 내측 밀봉 물질을 갖는 절연 변위 접속기에 관한 것이다. 이 접속기는 전선을 수용하기 위한 복수개의 채널과 상기 전선 사이에 전기접속을 제공하는 적어도 하나의 금속 요소를 갖는다. 상기 채널은 복수개의 함몰부와 유체 연통하고 있으며, 이들 함몰부는 매스틱 또는 실리콘 그리스 등과 같은 밀봉물질로 충전되어 있다. 접속기가 개방위치에서 폐쇄위치로 되면 상기 금속요소는 전선 간의 접점을 형성하고, 이어서 피스톤 또는 포스트는 상기 함몰부로 진입함으로써 밀봉제를 전선 및 접점의 둘레에서 채널 내로 유동시킨다.

Title: Process for manufacturing stable chlorine dioxide acqueous solution
Inventor: KANG HAN-CHOL
IPC: C01B11/02
Filed: 1990-11-05
Granted: 1993-05-08
Abstract: This method prepares stabilized chlorine dioxide solution containing free ClO2. Chlorine dioxide is a strong oxidizer used as deodorant, disinfectant or bleaching agent, but it is so unstable that many methods have tried to stabilize it. In the production, 0.6-0.9 wt. pts 10 % sulfuric acid is added to 5-10 wt. pts sodium chlorite solution and pH of solution is controlled by absorbing ClO2 gas. The pref. pH of solution absorbing ClO2 is 7.5-8.5. The conc. of stabilized ClO2 solution is 3-5 %.
