Patent EP-0052348-A1 (EP)
Inventor: SCHILLER MICHAEL
IPC: A61B5/117
Filed: 1981-11-12
Abstract: A finger (F) pressed against a platen (32) provides a fingerprint object which is scanned by an interrogating beam of collimated light (30) in the form of a slit and that is linearly displaced across the platen. As the slit-beam scans across the back surface of the platen, the reflected light beam is modulated. The modulated beam is imaged onto a linear array of photodiodes (12) to provide a series of output signals indicative of modulation information. The outputs of the diodes are serially interrogated at each of successive scan positions to provide a set of signals containing fingerprint information. The platen has a transparent glass base (92). A layer of transparent, compressible, resilient epoxy (94) is on the back of the glass base (92). The epoxy layer (94) has a flat back surface. A thin silver reflecting layer (96) on the back surface of the epoxy provides a flat mirrored surface to reflect the light beam. A further epoxy layer (97) on top of the silver provides mechanical filtering. A lacquer layer (99) at the back protects the platen from wear. When a finger is applied to the back surface, the ridges of the finger distort the underlying layers sufficiently so that the reflected light at the ridge zones is scattered while the reflected light at the valley zones is collimated. This difference in scatter is transformed by an imaging lens (65) to a difference in intensity at the diode array (12).

Abstract: The present invention relates to an arrangement for controlling fluid flow through an aperture. 
     In one embodiment, the flow control arrangement, which may be used in association with a window to control the flow of ventilating air, comprises a strip brush composed of an array of resilient filaments (1) firmly mounted at their root region (2). The free end region (3) of the filaments (1) define, with a fixed flange (7), the effective area or width (9a) of an aperture (6) for the passage of ventilating air in the direction of the arrow (11). Variations in the strength of the air flow incident to the array of filaments causes changes in the degree of deflection of the filaments, thus altering the effective width (9a) of the aperture and controlling the air flowthrough the aperture.

Abstract: A system and method are disclosed for controlling blood flow or flow of biologic fluid in an artificial organ or extracorporeal blood circuit. Selected parameters relating to blood flow are sensed and used to automatically optimize blood flow while assuring proper and safe operation. Utilized in conjunction with a reciprocating dialyzer apparatus (21), the system controls blood flow into and out of the dialyzer apparatus by controlling pressure on a slurry around the dialyzer membrane package. Slurry pressure is controlled by an actuator (16), such as a bellows pump, the pumping action of which is controlled by an electric motor (21), which motor, in turn, is electrically controlled by a control unit (29) which receives sensed indicators of blood flow, pressure and/or motor current. Blood contamination is also monitored for assuring safe operation of the dialyzer apparatus.

IPC: E04G21/04

Abstract: When injecting concrete, the nozzle of the injecting device must perform a circular motion in order to avoid the formation of so-called beads. Since this is a laborious operation, the invention proposes an injecting device whose nozzle is provided with said motion by a mechanical drive. However, the feeding hose is not to perform said tumbling motion in order to the hazard of buckling, among other things. For said purpose serves a hydraulic motor (2) whose eccentric (1) provides the hose holding means (3) with a circular tumbling motion, said motion taking effect on the end of the feeding hose (6), said end being secured in hose holding means (3), and thus on the nozzle (7), whose mouth describes a circular motion. The hose holding means (3) is secured against twisting by the cross joint shaft (4). The four chains with links (8) arranged around the feeding hose with 90 degrees displacement against each other, jointly with the cross rings (9) prevent an excessive deflection of the feeding hose (6) and thus buckling of said hose, which would lead to increased wear and trouble during the injection of concrete. Said injecting device significantly facilitates the per-se laborious injecting of concrete, in particular of vaulted constructions.

Abstract: A device for vacuum tensioning films onto the drums of scanners. Modern scanners rotate very quickly; the film is subjected to great centrifugal forces and must be sucked on without deformation over its entire surface.

Abstract: A hydraulic reset mechanism is provided for an engine retarder of the compression relief type. The mechanism includes a pin valve and senses the force required to hold open an exhaust valve. When this force has decreased substantially from the force required to open the exhaust valve initially, the pin valve is opened in the hydraulic system to release the hydraulic pressure and permit the exhaust valve to close. The mechanism thereby assures that the engine exhaust valves are closed, or substantially closed, prior to the normal opening of the exhaust valves at the end of the power stroke of the engine without affecting the retarding horsepower produced by the engine brake.

Abstract: Systeme de commande de moteur a quatre cylindres (10) pour commander les fonctions d'allumage ou d'injection de combustible. Le systeme de commande comprend un appareil d'identification de cylindre (30, 50, 60) qui fonctionne conjointement avec un organe rotatif (11) mu en rotation par le vilebrequin du moteur ayant des saillies de distribution (14, 117) correspondant aux positions specifiques de rotation du vilebrequin. Une paire de detecteurs fixes (20, 21) detecte le passage des projections de distribution et envoie des signaux correspondants a un circuit de commande et de calcul de la distribution du moteur (40) qui envoie des signaux de commande qui sont achemines sequentiellement et selectivement pour commander l'allumage et/ou l'injection de combustible des cylindres du moteur dans une sequence predeterminee. Une saillie de distribution (14) comprend deux extensions radiales individuelles (15, 16) tandis qu'une autre comprend une seule extension (17). Un appareil d'identification des cylindres utilise des impulsions de detection (200, 201) fournies par les detecteurs fixes pour distinguer entre le passage de la paire d'extensions par rapport au passage de l'extension simple et produit une impulsion d'identification des cylindres (207) indiquant la position de rotation du vilebrequin du moteur. Ceci s'effectue par un premier circuit de rejet d'impulsions (60) qui fournit une sortie lorsque l'un des detecteurs produit deux impulsions avant que l'autre detecteur ne produise une impulsion ulterieure. Cette sortie est ensuite utilisee pour initier le portillonnage sequentiel des signaux de commande sur l'appareil de commande des cylindres.

Abstract: A dot matrix printer which makes use of multiple dot patterns distributed on the cylinder, belt, hand or drum of a line printer to provide an improved printing throughput for an all addressable line printer. In a dot helix matrix printer, different arrangements of the dots are used which can be varied in position and spacing to increase printing speed. On a belt, band or drum line printer, multiple dot patterns are given a predetermined distribution. More specifically, arrangements of dots are used which provide enhanced performance due to the fact that they are determined by an analysis of the statistical occurrence of a particular dot pattern in a character set. The higher statistical probability dot patterns are used more often on the belt, band or drum.
