Patent EP-0399279-A1 (EP)
Inventor: ETZBACH KARL-HEINZ DR
IPC: C09K19/10
Filed: 1990-05-07
Abstract: Novel laser-optical recording elements in which information can be repeatedly deleted and reentered contain recording layers (a) which have enantiotropic, ferroelectric smectic liquid-crystalline (Sc) behaviour, as a result of which they can be switched back and forth between two thermodynamically stable, optically distinguishable, ferroelectric smectic liquid-crystalline Sc ordered states upon irradiation with a laser beam of sufficient light output by applying an external electric field. The recording layers (a) themselves mainly or exclusively comprise novel polymers P having chiral mesogenic side groups. The novel polymers P are prepared by using the novel monomers of the general formula I <IMAGE>  in which R denotes a hydrogen or chlorine atom or a methyl group, A denotes a flexible long-chain molecule portion which maintains the spacing,  C denotes an optically active chiral molecule portion and B denotes a mesogenic molecule portion composed of at least three aromatic rings which are linked with one another linearly or approximately linearly, or they are prepared by using novel monomers I which contain specifically selected molecule portions B in a novel combination with selected molecule portions C.

Abstract: The cover (1), made of elastically deformable plastic, has a hollow section (1b) at the bottom of which a slit (4) is provided which is inclined with respect to the general plane of the said cover. Because of this inclination, a forward edge (1c) of this slit (4) covers the other, rear edge (1d). A pressure applied to a portion (1e), in relief with respect to the forward face (3) of the cover (1), produces a deformation of the edge (1d) of the slit (4), which opens the latter. When the cover is used on a cup containing a drink, the user automatically applies this pressure by means of the upper lip when taking the cup to his mouth and this allows him to drink straight out of the said cup. <IMAGE>

Abstract: The invention relates to a device for strain relief for flexible printed-circuit boards which are soldered directly to conductor track connections on rigid printed-circuit boards. The transmission point from the solder region to the wiring region is always at risk of fracture in the case of flexible printed-circuit boards. This is prevented by means of the invention in that, on the side of the flexible printed-circuit board (4) provided for connection to the rigid printed-circuit board (6) a clip (7) of rigid material, such as fibre-reinforced epoxy resin, is laminated on, which is cut away in the region of the solder point (5) and is additionally provided with flaps (13) in which there are holes (12) for mounting screws (8). <IMAGE>

Abstract: Device for cutting off a workpiece, with a periodically moving tool holder (1), at least one blade-like tool (2), a tool support, and a drive (4) acting on the tool holder (1). The drive (4) imparts a rocking motion with parallelogram-link kinematics and a predetermined oscillation radius to the tool holder (1). The tool (2) has a non-rectilinear cutting edge (6) which produces a cutting-off gap in the workpiece and generates in the cutting-off gap a base surface corresponding to the width of the cutting-off gap and having a predetermined cut contour (7). The cutting edge (6) is constructed in a circular arc shape with a circular-arc radius Rb  and generates a circular-arc cut contour (7) with the cut-contour radius Rw. Rb is greater or less than Rw. The oscillation radius Rs is selected such that working contact in the form of quasi-point contact takes place between the cutting edge (6) and the cut contour (7).

Abstract: A microscope is provided with a supplementary means for producing a light spot in the object plane of the microscope objective lens. The supplementary means comprises a light source from which a collimated light beam is derived, a focusing lens receiving the collimated beam and a coupling lens disposed between said first lens and the objective lens. The supplementary means has the following features: 
(i) the focal point of the focusing lens is in the plane of the image of a specimen in said object plane as obtained through the objective lens and the coupling lens, 
   (ii) the light beam fills the clear aperture of the objective lens without substantial light loss and (iii) the focusing lens is movable in a plane perpendicular to its axis to the light spot in the object plane of the objective lens, the parameters of the system are such that the axial ray of light from the light source always passes through the second principal point (i.e. that on the object side) of the objective lens. In one embodiment the focusing lens and the light source are movable together perpendicularly to said axis. In a second embodiment the focusing lens is movable perpendicularly to said axis relatively to the collimated light beam.

Abstract: The invention relates to a metal barrier which can be adapted to all differences in level and to all angles between the frames and it permits minimum-cost opening. It consists of vertical posts (1) to which are welded linking elements (4) holding the frames (3) in the groove by means of small bars (5) with a tamper-proof headed screw. In order for a frame string to move, it suffices to add a flat washer to one of the sides, onto the screw (6) between the elements (4) and (5) so as to give the frame play and to replace the small bar (5), on the side opposite the frame, by the small bar (7) together with its screw (10) and its spring (11). This small bar, by pivoting one quarter of a turn, releases the frame, which thus becomes a gate. <IMAGE>

Abstract: Packaging, partic. food in dishes, with a special heat sealable paper is by using a machine with at least one transversal (6) and at least one longitudinal (6') treated element, mounted at a work station. Elements have a lower (5) bar fixed to a chassis and an upper (6) tilting bar which together function as a vice able to fasten the edges of the continuous paper sheets in the desired position around the article to be packaged. Mating faces of the upper and lower bars have corresp. teeth and channels to assure the deformation of the double paper layer. Other faces have channels in which are located electric-resistance heating elements. The transversal element has double bars (5',5") or (6',6") between which slides a cutting blade, in syncronism with the other mechanism, to cut the sealed paper sheet(s).

Abstract: In a window or windscreen arrangement on a vehicle body (11), the opening for the window or the windscreen (18) has a mounting flange (12) which is stepped towards the inside of the vehicle. The pane (18) is bonded in an edge region to a mounting flange component (13). Along the edge, facing away from the window opening or windscreen opening, of the mounting flange component (13), a slit seal (15) is bonded securely in position. The latter is formed by an elastically deformable hollow profile body which is continuous or of specific length, essentially corresponds to the circumference of the pane (18) to be bonded in, can be bonded securely to the mounting flange (12) and is enclosed on all sides. In addition to other technical and optical advantages, the use of the proposed slit seal (15) is substantially cheaper than conventional sealing or covering designs and covers the slit from below between pane (18) and mounting flange (12) reliably even given the presence of all the constructionally conditioned size tolerances.

Abstract: The present invention relates to a method to increase the strength of an element for percussive drilling, said element being made of hardened steel and transferring impact energy in its axial direction, said method involving deep rolling of the surface layer of the element, at least in certain sections. The invention also refers to an element worked in accordance with the method of the invention. 
     Fatigue cracks in elements of the above mentioned kind are initiated in areas having an intensive dislocation motion. Such areas are originated near notches and parts having sharp-edged corners. 
     The aim of the present invention is to remedy the influence that "poor surfaces" have upon the fatigue strength. 
     The main characterizing feature of the invention is that said deep rolling of elements for percussive drilling creates a surface finish ≦ Ra 1.0.

C'est ainsi que la durée de 60-75 secondes requises pour le traitement au Plastisol des bouchons, utilisé par l'ancienne méthode, se réduit aux quelques secondes nécessaires pour le traitement des bouchons faits à partir d'un polymère. Les bouchons ont été conçus avec des nervures de renforcement pour minimiser la quantité de polymère nécessaire tout en continuant à maintenir une force de bandage suffisante pour retenir le réseau en place.
