Abstract: 본 발명은 액체를 밀봉한 2개의 가요성 용기의 한쪽이 공이 되면 다른쪽에 자동적으로 전환하는 공급 방식일 때, 각 용기 더불어 공 내지 공에 가까운 상태로 되었다는 것을 검지하고 필요한 처리를 강구할 수 있게 한다. 
     액체를 밀봉하는 2개의 가요성 용기가 전환 밸브를 거쳐서 액체 흡인 수송용 펌프와 접속되며, 펌프를 제2소정시간 만큼 동작시켜서 그 동작 종료시점에서 제2소정 시간후의 전환 밸브 펌프사이에 배관 압력의 값이 설정 값 이하인 것에 의거하여 한쪽에서 다른쪽으로 전환 밸브가 전환됨과 더불어 이 전환 동작이 제3의 소정 시간 내에 2회 계속해서 행해진 것에 의거해서 각 용기는 공 내지 공에 가깝다고 판정된다.

Granted: 1999-09-01
Abstract: The invention relates to a device for applying dot-shaped coatings to metal or metallized bands by means of an electrolysis process or by means of currentless metal extraction, said device being provided with a wheel-shaped guide means, along which a metal or metallized band can be passed, and with an endless masking means, which co-operates with said band during operation and which is provided with passages, whose shape is adapted to the desired dot-shaped coating. The masking means is built up of independent masking segments, which are each provided with at least one passage and which are mutually coupled in such a manner that they can move with respect to each other in the longitudinal direction of the masking means. Inner boundary planes of the masking segments co-operate with a circular supporting surface of the wheel-shaped means, and measured in the longitudinal direction of the masking means the total length of said inner boundary faces is larger than the length of the circular supporting surface of the wheel-shaped means. <IMAGE>

Title: Improved method for nucleic acid amplification
Inventor: TIM KIEVIZ
IPC: C12Q1/6844
Filed: 1993-08-23
Granted: 2000-12-15
Abstract: The present invention relates to an improved method for the amplification of nucleic acid. The invention is characterized in that ribonucleotides are introduced during amplification that weaken normal basepairing. Preferably the ribonucleotides are inosine-triphosphate nucleotides which partly substitute guanine-triphosphate nucleotides normally present in the amplification reaction mixture. The incorporation of nucleotides, during amplification, that weaken normal base pairing prevents the formation of secondary structures in the amplificate. The efficiency of the amplification is thereby increased. The introduction, during amplification, of nucleotides that weaken normal base pairing also results in an improved sensitivity during detection of the amplified nucleic acid, when the detection method comprises the hybridization of the amplified nucleic acid to a complementary sequence.

According to the invention, the device comprises a support (1) mounted on a broach-holding housing (2) of the boring and milling machine-tool, which exhibits at its outer part, in the vertical plane, a circular T-shaped groove, a grinding-stone-holder (3) being mounted on said support (1) in a horizontal or vertical position, and being locked by means of some screws (8), while inside there are two bevel gears (4) transmitting the grinding-stone planetary motion from a broach (5) of the boring and milling machine, the rotation motion of the grinding stone being performed by an AC motor (7) supplied through a rotative collector (17), while inside the stone-holder (3) there are two eccentric axles (9 and 10), the modification of the relative position thereof by using a worm gear (11) ensuring a maximal adjusting stroke (22).
