Filed: 1985-01-18
Abstract: A device for preventing air contamination when transferring a substance from a vessel (24) to a second vessel (10; 15) and further to the desired application, for example injection into a patient or other application. The device is attached or connectible to said vessel (24) and comprises a first member (10), in which a puncturing member (16), e.g. a needle provided with a passage is enclosed. The first member (10) has a sealing member (18), e.g. a membrane through which the needle can be passed. The device further comprises a second member (20), which is detachably connectable to the first member (20) and which also has a sealing member (19), e.g. a membrane. When the first and second members (10, 20) are connected to each other the two sealing members (18, 19) are located in a position with respect to each other so that they can be penetrated by the puncturing member (16), which is movable with respect to the sealing members (18, 19).
Patent NO-161309-C (NO)
Inventor: HOYER PETER
IPC: B66C1/48
Filed: 1985-06-21
Abstract: The hoist clamp has a coupling eye (7) which has a gimbal-type connection by means of the shafts (5,6) to clamp operating crank (14). When a diagonal pull is exerted, the neck (42) of the coupling eye (7) engages against a bracing point (3,4) which is sufficiently high above the shaft (6) to ensure that the lever action provides extra clamping force between the clamps (11,12). When the coupling eye (7) swings about the shaft (5), the coupling eye engages against the upper edges (1,2) of the casing (8), said edges curving outwards, so that additional clamping force is also obtained when the pull exerted is diagonal. Said additional clamping force is only marginally affected by the load (32) held in the load aperture (37).

Title: Compound laminate containing diffraction elements
Inventor: MINNETIAN OHANNES
IPC: B42D25/328
Filed: 1990-04-30
Granted: 1999-11-02
Abstract: A compound laminate containing a diffraction element which, for the purpose of rendering the falsification of a document, for example, more difficult, is glued to a substrate by means of an adhesive layer, using heat. The compound laminate includes a transparent stabilizing layer which uniformly distributes the heat, during the gluing process in the compound laminate, until the adhesive layer softens. Upon cooling, the adhesive layer forms a firm joint with the substrate. By means of an intermediate layer, the stabilizing layer is joined to a first layer of lacquer having engraved diffraction elements. A second layer of lacquer masks the diffraction elements and serves as a carrier for the adhesive layer. Tags in which the diffraction elements have a conspicuous, optically variable composition may be stamped or cut from the compound laminate.

Abstract: The light receiving or back-side surface (22) of an indium antimonide  (InSb)  photodetector device  (10)  sub-strate (12) is cleaned to remove all oxides of indium and antimony therefrom.  Passivation and/or partially visible light blocking layers (26, 28) are then formed thereon of a material which does not react with  InSb to  form a structure which would have carrier traps therein and cause flashing.
