Title: Method for treatment of oxidized metal surfaces
Inventor: SCHAFER I
Filed: 1977-10-28
Granted: 1981-05-25
Abstract: A rust-converting coating material was disclosed for application on rusted mild steel without any surface pretreatment to give a nonporous, strongly adhering layer containing no Fe oxides.  The coating material contained urea 5.3, CoSO4  0.5 H3PO4 (100 % basic) 58.0, and water 36.0 %.  When the rusted and coated steel was exposed to the atm. for 14 days with sprinkling twice daily little rust gathered similar results were obtained when tarnished brass, Cu, and Al were coated with the rust-converting material.

Inventor: TOWNS EDWARD J
IPC: B65D41/04
Filed: 1983-11-12
Granted: 1988-05-31
Abstract: The cap is transparent and carries depending teeth which engage a resilient pad when the cap is applied.  When the cap is removed for the first time, the teeth tear the pad and this can be viewed through the cap to provide a visual indication that the cap has been removed.  The torn section of the pad is retained within the cap and cannot be removed by a user.  In an embodiment, the pad is a laminate and provides a contrasting background aginst which the ruptures in the pad can be viewed.  The closure is applied to a container holding a medical prod. to provide evidence of tampering. The evidence of tampering is directly visible and does not require prior knowledge of the cap construction.

Filed: 1988-11-05
Granted: 1997-05-07
Abstract: A novel composition and method for solubilizing amphiphilic drugs in a small amount of organic solvent for use in improved liposomes is disclosed. A phosphatidylglycerol is acidified in a small amount of organic solvent. The amphiphilic drug, such as Amphotericin B, suspended in organic solvent is then added to the acidified phosphatidylycerol and a soluble complex is formed between the phosphatidylglycerol and the amphiphilic drug. When the liposome composition incorporating the soluble complex is hydrated, the final pH of the hydrating aqueous buffer is carefully controlled. The Amphotericin B liposomes formed have markedly reduced toxicity.

Abstract: The gear is equipped with a mechanism by which a steering wheel is rotated in accordance with the steering operation of a player and returns automatically to a neutral position. An end cam which receives the resilient force of a compression coil spring sets normally a steering wheel to a neutral position through a guide roller. When the player rotates the steering clockwise, for example, the guide roller rotates clockwise along with a steering shaft, so that the end cam moves in accordance with the rotating angle of the steering wheel in the axial direction of the shaft. When the wheel is released, the end cam returns the steering to the neutral position through the guide roller upon reception of the resilient force of the coil spring without the need of a reversing operation. The steering gear has a detector for the rotating angle and rotating direction of the shaft to operate a car on a display. @(21pp Dwg.No.2/6)@.

Abstract: 이 발명은 디지탈 오디오 신호를 처리하는 오디오 프로세서를 사용하는 모든 전자 및 전기기기에 관한 것으로서, 제어부를 이용하여 리모콘 또는 기기에 부착된 키 패널의 키눌림에 따른 오디오 데이타의 감쇄정보를 출력하여 오디오 신호의 음량이 제어되도록 하고, 제1 및 제2음량감쇄부를 이용하여 상기 제어부의 제어에 따라 입력되는 오디오 데이타의 음량을 상호 교대로 감쇄시키며, 멀티플렉서를 이용하여 상기 제어부의 제어에 따라 상기 제1, 제2음량감쇄부의 오디오 신호를 교대로 출력하도록 함으로써 디지탈 오디오 데이타의 음량제어를 종래와 같이 디지탈 아날로그 변환기를 사용하여 아날로그 신호로 변환하여 처리하지 않고 직접 디지탈 방식으로 처리하므로 별도의 아날로그 볼륨제어부를 구성하지 않아도 되므로 회로가 간단해지며 또한 볼륨제어시 음량차를 정확히 느낄 수 있어 단 한번의 조절만으로도 원하는 음량을 얻을 수 있게 되는 것이다.
