Patent EP-0576604-A1 (EP)
Inventor: KAMEN DEAN L
IPC: A61M5/152
Filed: 1992-03-20
Abstract: The invention provides a system for dispensing fluid at relatively constant pressure. In a first embodiment, the invention dispenses a fluid from a chamber of varying dimension defined by a pre-tensioned resilient membrane. In a second embodiment, the invention dispenses a fluid from a chamber defined by a dispensing membrane, which is substantially surrounded by another fluid contained within a pressure chamber of varying dimension defined by a pre-tensioned resilient membrane. In a third embodiment, the invention dispenses multiple fluids, a first fluid from a first dispensing chamber of varying dimension defined by a pre-tensioned resilient membrane, and a second fluid from a dispensing chamber of varying dimension defined by a dispensing membrane substantially surrounded by the first fluid. In a fourth embodiment the invention dispenses multiple fluids from at least two dispensing chambers of varying dimension each substantially surrounded by the pressure fluid contained within a pressure chamber varying dimension defined by a pre-tensioned resilient membrane. In a preferred embodiment, the resilient membrane is pre-tensioned beyond the point at which, as fluid enters the volume contained by the membrane and the volume increases, the first derivative of pressure over volume becomes zero for the first time.

Title: Immersion casting pipe for thin slabs
Inventor: HOFMANN GEORG
IPC: B22D41/50
Filed: 1992-06-22
Abstract: The invention is directed to an immersion casting pipe for feeding molten steel from a casting vessel into a mold having wide side walls and narrow side walls for the production of flat products. The immersion casting pipe has a pipe piece which adjoins the casting vessel and expands in cross section in the direction of the narrow side walls of the mold. The pipe piece is provided with a central base member at the lower end which allows for outlet openings for the melt. For the purpose of developing an immersion outlet which allows higher slab withdrawal speed of up to 6 m/min with slabs measuring 50 to 100 mm in thickness and 600 mm to 2000 mm in width, the inner wall of the portion of the immersion casting pipe which widens in cross section forms flow channels in conjunction with the opposite wall parts of the base member. The axes of the flow channels enclose an angle  alpha  between 10 DEG  and 22 DEG , where the smaller angle corresponds to a distance of approximately 600 mm between the narrow side walls of the mold and the larger angle corresponds to a distance of 2000 mm or more between the narrow side walls of the mold. The distance between the wide side walls of the mold is 50 to 100 mm.

Title: Power conductor rail.
Inventor: PLICHTA DIETMAR G
IPC: B60M1/30
Filed: 1992-11-09
Abstract: In accordance with the present invention, a power conductor rail structure is provided using a multi-metallic construction. The composite rail of the invention includes an asymmetrical steel portion having a top flange thickness greater than that of the bottom flange in a generally I-shaped configuration with spaced apertures along the length of the web. Aluminum cladding is cast onto both sides of the web with a cold rolled high conductivity layer, such as copper disposed between the aluminum and steel on either side of the web and having holes corresponding in size and shape to the apertures of the web. The aluminum cladding extends through the web apertures producing a multi-metallic sandwich construction. The high conductivity layers provide a mechanical bond between the steel and aluminum and reduces transfer resistance and increasing overall conductivity. In an alternative embodiment of the invention, the top flange is formed with openings with the aluminum cladding filling the openings so that the aluminum cladding forms part of the electrical contact surface.

Abstract: A method for a minefield simulation includes a number of troops (30) and vehicles (31,32) each including a player detection device or vehicle detection device (51-57) respectively. The player detection devices and vehicle detection devices determine and transmit their respective locations to a central computer (10). The central computer or player determines whether the player is within an activation radius (20) of a mine in the minefield. The central computer or player has established a bit map (40) of the minefield with indications of the exact placement of the mines within the minefield. If a player (troop or vehicle) is within the activation radius of a mine (70), the central computer or player records (72) the identity of the expended mine in the minefield bit map by changing its indication from active (44) to inactive (43). Either central computer (10) or the player detection device (51-57) may determine the effects of the expended mine upon the troop (30) or vehicle (31,32).

IPC: G02B6/44
Filed: 1993-12-14
Abstract: A method for monitoring the thickness of a hermetic coating on an optical waveguide fiber is provided in which an interference pattern is produced by illuminating the fiber with a laser beam. A spatial frequency spectrum is generated for the interference pattern and a first component of that spectrum, corresponding to the outside diameter of the fiber, is identified. The magnitude of this component is inversely related to the thickness of the coating, i.e., the magnitude decreases as the coating thickness increases, and thus this magnitude can be used to monitor the thickness of the coating during, for example, the coating process. Effects of fluctuations in the power of the laser beam and/or movement of the fiber relative to that beam can be minimized by normalizing the magnitude of the first component by the magnitude of the PC component of the spatial frequency spectrum.

Abstract: The device (1) for admixing a pourable component to a liquid based composition contains a vessel (2) which has at least one stirrer (10, 11) rotatable about a vertical axis (3). The device (1) further has a line (14) which is connected to an inlet (6a) and an outlet (8) of the vessel (2) and through which at least part of the liquid based composition is passed. During operation of the device, the pourable component, for example a pulverulent drug is admixed particulately, via a solids introduction appliance (17) arranged in the line (14), to the liquid base composition passed through the line (14). This manner of solids uptake has the advantage, compared to previously known methods, that the pourable component is dispersed relatively rapidly and uniformly in the material and that no agglomerates of solid particles are formed when this component is introduced. Moreover, the components of the material being mixed are blended optimally as a result of the fact that the material flowing back into the vessel (2) is homogenised gently by a turbulence tube (vortex tube) (18) and is dispersed uniformly in the interior (7). <IMAGE>
