Patent EP-0002945-A1 (EP)
Inventor: SMITH EDGAR CHARLES
IPC: G03B35/00
Filed: 1978-12-21
Abstract: An apparatus and method of making a parallax stereogram, i.e., free vision stereogram, and particularly for the accurate registration of a plurality of film images in order to ensure stereographic reproduction. Each film frame having the image thereon includes marks which are used in a projection printing apparatus (13) to register the image in a desired position. The registration is accomplished by mechanical alignment according to the mark or by optically sensing the mark. A comparator-servo can adjust the film frame to the desired position. After registration each film frame is exposed onto a photosensitive material (95) using a movable line grid (97). A lenticular screen is superimposed over the developed picture to form the stereoscopic photograph.

Abstract: The present invention relates to a communications transmission system wherein there is superposed, on the conventional analog telecommunication network, a digital network whose digital local exchanges are connected with digital subscriber stations. Both networks are interconnected between the analog and digital local exchanges by way of analog/digital converters and digital/analog converters. In each digital subscriber station, a data transmission is possible simultaneously with voice transmission due to an automatic sub-channel formation by means of a multiplexer and a demultiplexer. An arrangement is provided for data clock pulse recognition to determine at which bit rate the respective data terminal operates, and causes a suitable sub-channel for the data to be arranged with a bit rate which is obtained from the voice channel.

Abstract: Um eine homogene kristalline und gut reproduzierbare Abscheidung von Chromogenen in Kapillaren, insbesondere für die Serienfertigung zu erzielen wird die Auskristallisierung des Chromogens aus einer Lösung zunächst durch eine relativ starke Übersättigung ausgelöst und läuft danach bei einer demgegenüber gering übersättigten bzw. gesättigten oder nicht übersättigten Lösung ab. Die Verdunstungsgeschwindigkeit wird beispielsweise durch die Wahl der Lösungstemperatur und/oder eines Lösungsmittelgemisches aus einer das Chromogen lösenden und einer das Chromogen nicht lösenden Komponente so gewählt, dass die Lösung in einen zwar gesättigten, eine langsame Kristallisierung ermöglichenden Zustand, nicht aber in einen stark übersättigten Zustand gelangt. Dadurch steht ausreichend Zeit für eine ungehinderte Kristallisation zur Verfügung. so dass sich das Chromogen nicht als amorphes Öl, sondern in kristalliner Form und ohne Pfropfenbildung abscheidet, wodurch die Saugfähigkeit der Kapillare erhalten bleibt.

Une soupape d'etagement (S), egalement disposee dans le passage d'induction est fermee pendant la mise en route d'un moteur, ce qui permet une alimentation appropriee en un melange air-combustible du moteur pour le faire demarrer. La soupape d'etagement se deplace vers une premiere position ouverte lorsque le moteur demarre et vers une position grande ouverte au fur et a mesure que le moteur chauffe. Des moyens (29) limitent le mouvement d'ouverture de la soupape d'etagement sur une seconde position ouverte qui est intermediaire entre sa premiere position ouverte et sa position grande ouverte. Ceci limite la capacite utilisable d'air du carburateur. Des moyens d'etagement (35) sensibles au mouvement du papillon au-dela d'une position ouverte predeterminee permettent a la soupape d'etagememt de se deplacer librement entre sa seconde position ouverte et une position plus ouverte seulement en reponse a la demande en air du moteur. La soupape d'etagement peut se deplacer librement vers sa position grande ouverte lorsque le papillon est totalement ouvert et ceci augmente la capacite utilisable d'air du carburateur jusqu'a son maximum.

Abstract: The present invention is directed to flexible polyurethane foam compositions and methods of preparation thereof, characterized by improved heat degradation properties, which are prepared by the reaction of an organic polyisocyanate with a polyol in the presence of a small but effective amount of a lower alkanediol. It is preferred that the alkanediol have from 2 to about 5 carbon atoms. Lower alkanediols that may be employed include 1,2-ethanediol (ethylene glycol), the propanediols, the butanediols, most preferably, 1,4-butanediol, and the pentanediols. By incorporating the alkanediol, improved resistance to heat degradation is achieved. Further, it has been discovered in accordance with the present invention that, with the incorporation of the alkanediol, the addition of conventional flame retardants does not increase foam degradation but, in fact, the combination improves resistance to heat degradation.

Abstract: This invention discloses an abnormal cell detecting device having at least a pair of electrodes (2a, 2b) to be attached to a portion of a body. At least one electrode (2a) of the pair of electrodes (2a, 2b) is constituted by a plurality of independent electrodes cells. One voltage at a frequency is applied between the pair of electrodes (2a, 2b), and another voltage of a different frequency is applied between them. As a result, electrostatic capacitances corresponding to the two frequencies are measured between the electrodes as voltages by a capacitance measuring unit (3). The ratio of the voltages is calculated by a division unit (7), and the resultant ratio is digitally sent out through an A/D converter (8) to a memory unit (9). Digital signals corresponding to a plurality of electrode cells are stored as image data in the memory unit (9). A dispay unit (10) displays the position and size of abnormal cells, based on the image data of the memory unit (9).
