Patent EP-0328501-A1 (EP)
Inventor: DIMATTEO JOSEPH HOWARD
IPC: G11B7/09
Filed: 1989-02-07
Abstract: A focus acquire circuit for use in optical systems, such as optical data recorders and players, uses up to three parameter signals to indicate an in-focus condition. The zero crossing of a focus error signal is combined with a signal indicating that the focus error signal has approached a peak value and with a signal indicating a change in laser drive signal amplitude to indicate an in-focus condition. Various circuit details are illustrated showing how the three parameters can be combined together for indicating an in-focus condition.

Abstract: Cette invention concerne un appareil permettant d'aligner des groupes de plaques et de séparateurs dans un groupe utilisé dans une batterie d'accus, et plus généralement un appareil d'alignement d'ensemble. Dans un mode de réalisation l'appareil d'alignement (19) comprend une table (20) montée sur un cadre que l'on peut lever à l'aide d'un vérin hydraulique (21) et faire vibrer au moyen d'un vibreur (22) à basse fréquence, agissant verticalement, et d'un vibreur (23) agissant horizontalement par cycles. Une tête (24) comporte des parois (25, 26) d'alignement de cosse alignant les plaques (31), tandis que les parois (17 et 18) alignent latéralement les séparateurs (30). Des poids (27 et 27A) agissent sur le dessus des plaques (31) et des séparateurs (30) respectivement pour assurer l'alignement vertical. Les vibrations combinées produites par les vibreurs (22, 23) libèrent les plaques et les séparateurs afin de permettre à ces alignements d'avoir lieu.

Abstract: Un appareil (100) et un procédé de spectrométrie en masse par chromatographie gazeuse pour le contrôle de la proportion d'isotopes permettent une analyse en direct de compositions d'isotopes avec une grande précision. En utilisant l'appareil et le procédé de l'invention, on introduit des échantillons dans un gaz porteur d'hydrogène dans un chromatographe à gaz (1), ces échantillons étant décomposés en composés discrets. Les composés discrets sont ensuite introduits dans un séparateur à membrane sélectivement perméable (10), en utilisant du palladium, un alliage de palladium ou autre matériau approprié, pour séparer le porteur d'hydrogène. Un gaz porteur de remplacement est introduit simultanément pour amener l'échantillon chromatographique dans un réacteur de combustion (30), un séparateur d'eau (60) et un spectromètre de masse (80) de contrôle des proportions d'isotopes. Le gaz porteur de remplacement est introduit à un débit plus faible que celui du gaz porteur d'hydrogène, permettant ainsi d'introduire dans le spectromètre de masse (80) des débits plus faibles de manière à améliorer sa précision. Les débits dans le spectromètre de masse (80) sont ainsi réduits sans aucune perte de fractionnement de l'échantillon. Un système de combustion amélioré est utilisé pour réduire le volume du système et égaliser la pression du système tout en asurant une combustion quantitative.

Title: Laminated frame assembly and method for using.
Inventor: LIEBERMAN AARON
IPC: B44C5/02
Filed: 1989-08-30
Abstract: Framing apparatus for framing snap shots and the like, including a flexible rectangular-shaped transparent sheet having an opaque frame printed about its perimeter. A pressure sensitive adhesive coating is coextensive with the aforementioned opaque frame. A transparent sheet of much thinner gauge than the first-mentioned sheet is releasably secured to the pressure sensitive adhesive coating. The unassembled frame is moved about the snap shot or picture to be framed. The transparent nature of the assembly facilitates viewing of the picture therebeneath, enabling the user to select any portion of the picture. A writing instrument may be employed to form an outline of the frame on the picture, or the thin gauge cover sheet may be removed and the photograph pressed against the heavy plastic sheet. The portion of the picture extending beyond the frame is cut away from the part of the picture being framed. The heavy gauge flexible sheet serves as an excellent guide for cutting the photograph about the frame without any danger of damaging the frame. When the picture is cut out before mounting, the thin gauge cover sheet is then removed and the photograph pressed against the heavy gauge plastic sheet. The opaque frame conceals the possible rough edged perimeter of the photograph providing a nicely finished laminated photograph and frame assembly. An alternative embodiment provides a foldable flexible transparent sheet for mounting and framing plural graphic material in a back-to-back fashion.

In order to be able to eliminate disturbing influences on the accuracy of the time at which the components are injected into the mixing chamber arranged in the mixing head and on the mixing ratio of the components, it is proposed to combine the mixing head and the proportioning device, comprising proportioning pistons and proportioning cylinders, into one constructional unit. <IMAGE>

Abstract: By means of this method and the arrangement, in the case of an automatic door, especially in the case of lifts with a controlled door drive which moves doors of a cabin door by means of a motor with a reduction gear and a mechanical drive, and moves doors of a shaft door via mechanical coupling elements, protection against being caught, responding up to the last few mm of a door closing movement with constant force levels, is provided. In this case, this is done by a control error dV being continuously compared during the door closing movement with a maximum permissible control error dVmax produced by a nominal value sensor (3.5) and, if this maximum control error is exceeded, the door is stopped with subsequent reversing. The response levels for an external disturbing force (3.9) are kept constant by a calibration trip computer (3.11) determining values for mass compensation (3.12) and values for friction compensation (3.13) during periodic calibration trips and supplying these values as a compensation value Vk to a second comparator (3.2). In consequence, the magnitude of an external disturbing force (3.9) is also known, or can be measured precisely, with a defined gain of the controller (3.8) and a known torque characteristic of the DC motor (2.1), which creates the precondition for safe protection against being caught.

Abstract: An individual tooth implant with a conical retention part 1, which is provided with displacement extensions 3. It is desirable for the implant to be introduced into the prepared alveolus and held therein without drilling deeply into the jaw bone. This is achieved by the displacement extensions being designed as wedge-shaped, sickle-shaped retention wings 3 which are provided lying opposite one another on the retention part 1. Since the retention part is conical and the retention wings have an oval cross-section, the individual tooth implant can be introduced dimensionally stable into the prepared alveolus and, by means of a maximum rotation about 90 DEG , can be given a primary stability in the interradicular alveolar bone.
