Title: Electrode fixed and stabilised by vacuum
Inventor: LUNDBAECK STIG
IPC: A61B5/296
Filed: 1984-10-25
Granted: 1991-08-08
Abstract: The invention relates to an electrode intended, for example, for electrocardiogram examinations, and capable of being held in position by suction. Vacuum conditions are created through a hose or tube (8), through which a measuring conductor (7) is drawn. The electrode comprises an inflexible backpiece (3), an intermediate component (2) made of an elastomeric material, and an electrode plate (1), preferably made of a silver-coated plastics. The intermediate component (2) includes a relatively inflexible sealing ring (9) which, in the operative state of the electrode, supports against the skin of a patient via a sealing lip (13) and against the opposing side of the backpiece (3). The electrode plate (1) is firmly connected to the backpiece, while the sealing ring carried by the intermediate component (2) is movable and can be readily sprung away from the backpiece (via resilient means 17). When no load is exerted on the lip-side of the ring and the ring is thus urged outwardly, a vacuum valve is closed automatically through the intermediate component (2), and is re-opened when the electrode is pressed against the surface of the skin, whereupon the electrode is held firmly by suction.

Abstract: 이산 및 1,4-부탄디올 사이의 직접 에스테르화 반응 속도를 증가시키고, 유기-티타늄, 유기-주석 및 유기-지르코늄 화합물들로부터 선택된 촉매 화합물, 이산, 1,4-부탄디올을 임의의 순서로 혼합시켜 반응 혼합물을 형성시키고나서(이때, 디올 : 이산의 비는 적어도 2 : 1이다) 190℃-240℃의 평균온도 범위에서 60분을 넘지않는 시간동안 반응 혼합물을 반응시켜 이산의 산 말단 95% 이상을 직접 에스테르화시키기 위한 방법. 
     동일 방법은 1,4-부탄디올대신 에틸렌 글리콜로 대치시키는 것에 따를 수 있고, 이때 촉매 화합물은 순수하게 첨가되고, 평균 반응 온도는 190℃-200℃의 범위이고, 반응 혼합물은 70분을 넘지않는 시간동안 반응된다. 상기 방법으로부터 결과되는 생성물은 중축합되거나 더 처리되어 고 분자량 중합체를 형성시킬 수 있다.

Abstract: The apparatus continuously and automatically forms the gutter mounted on the eaves of house for covering the sunshine or receiving rain water. The gutter has curling section (71), primary slanted section (72), curved section (72), seconday slanted section (73), elongated from the left side of horizontal groove section (75); primary vertical section (76), horizontal section (77), secondary vertical section (78) elongated from the right side of the section (75). The apparatus comprises upper/lower rollers (10A,10B-50A,50B) necessary for first-fifth processes. First rollers (10A)(10B) have flat surface in axial direction, second rollers have round surface (23) at a side of slanted surfaces (22A)(22B), vertical surface (24) right-angled with horizontal surface (21), third rollers have semicircular groove ring (31) for forming semicircular groove ring, forth rollers have curved groove ring (41) on slanted surface (22A), fifth rollers have curved groove ring (51) on slanted surface (52).
