Abstract: The lower profile element is substantially of a U-shaped section and includes wings having each a median zone with a semi-cylindrical channel prolongated by a bent-over portion provided for covering V-bent vertical ends of side branches of the upper profile element. A wing of the lower profile element is cut out in order to form a row of teeth having each a trapezoidal shape prolongated by a rectangular shape in order to cooperate with an L-section latch-comb formed with rectangular openings and freely mounted on a pin which is displacable by a control of the slide.

Title: Phase adjustable metering pump
Inventor: PINKERTON DENNIS
IPC: F04B13/00
Filed: 1991-03-05
Granted: 1995-07-11
Abstract: A valveless, positive displacement metering pump is provided by the invention. Such a pump includes a housing (22), a working chamber (24) within the housing (22), a piston (82) within the working chamber (24), the piston (82) including a duct (86) defined by a portion of its outer surface, one or more inflow ports (96) communicating with the working chamber, one or more outflow ports (96) communicating with the working chamber (24), and a drive cylinder (66) for simultaneously rotating the piston (82) and causing it to move in back and forth strokes within the working chamber (24). The housing (22) is rotatable with respect to the piston (82) to adjust the timing of the fluid communication between the duct (86) and the inflow and outflow ports (96), respectively. Such adjustments in timing allow the flow rate of the pump to be fine tuned, and allow each port (96) to experience a partial suction as well as a partial discharge. It also allows backflow to occur in an inflow line (96) to the pump, thereby cleaning any filters within the inflow line (96) or agitating a suspension from which the inflow line (95) draws fluid. It also permits suction to be applied to an cutflow line (96) at the end of a discharge stroke, thereby preventing hanging drops or strings from forming at the discharge end of the outflow line. In addition, timing adjustement allows the manufacture of relatively inexpensive pumps in which the axes of the drive cylinder (66) and working chamber (24) are maintained in fixed positions relative to each other. A method for adjusting the flow rate of a valveless, positive displacement metering pump is also provided which includes adjusting the phases at which the piston duct (86) communicates with each of the ports (96) of the pump. <IMAGE>

Abstract: 전압 변환 회로 또는 부하 구동 회로를 갖는 반도체 집적 회로 장치로서, 외부 전원 전압의 변동에 대한 내성이 저하하는 것을 해소하기 위해서, 외부 전원 전압과 접지 전압의 중간의 전압을 발생하는 중간 전압 발생 회로와 이 중간 전압을 기준으로 해서 안정화된 내부 전원 전압을 발생하는 2개의 전압 리미터 회로를 마련한다. 
     이러한 반도체 집적 회로 장치를 사용하는 것에 의해, 외부 전압이 변동하여도 회로간에 논리 스레쉬홀드 불일치가 발생하지 않아 회로의 신뢰성이 향상하고 저논리 진폭에서도 고속 동작이 가능하게 된다.

Title: Liquid membrane modules with mininal effective membrane thickness and methods of making the same
Inventor: PRASD RAVI
IPC: B01D63/02

Granted: 1995-08-03
Abstract: Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness. The modules [10] have a module case [C] and at least one pair of superposed fabric sheets [12,14] disposed within the case [C], the fabric sheets being pleated and nested in the lengthwise direction of the case. Each fabric sheet [12,14] contains warp-wise extending hollow fiber membranes [Ff, Fs]. The hollow fiber membranes [Ff] within the folds of one fabric sheet [12] will therefore form alternating rows with the hollow fiber membranes [Fs] within the folds of the other fabric sheet [14] by virtue of the length-wise nested pleating. As a result, the effective membrane thickness value of the module is minimized thereby enhancing the efficacy of fluid separations. <IMAGE>

Title: Error correcting method for shading data reading
Inventor: LEE KWAN-JOONG
IPC: H04N1/00
Filed: 1992-05-28
Granted: 1996-10-15
Abstract: A facsimile using the method has a contact image sensor, a white roller and a memory for storing a shading data. The method comprises the steps of; setting up reading repeat number of shading data and initializing a shading data, detecting and rotating white roller, reading a pixel value according to quantity of reflecting light, revising shading data and returning to the second step.
