Granted: 1992-03-03
Abstract: Apparatus whereby a filament web impregnated with resin in the unpolymerized state is fed to a pole (1) at a predetermined angle ( alpha ) with respect to a plane perpendicular to this latter. The pole (1) is drawn in rotation about its axis (X-X') and the filament web is displaced along the pole from the bottom end to the top end thereof in a direction parallel to the axis of the pole while this latter is being driven in rotation. A plurality of parallel fiber slivers (8, 9, 10) spaced a distance apart are fed simultaneously to the pole (1) in a plurality of layers. The spacing between the slivers is progressively increased during displacement of the slivers between the bottom end and the top end of the pole and progressively decreased in the opposite direction. Similarly, the angle of the slivers to a plane perpendicular to that axis is progressively increased and decreased in the same directions that the spacing is increased and decreased. The apparatus is useful for forming a reinforcement wound structure of filaments on a cylindrical pole (1) of plastic material, the wound structure of filaments having a density which progressively decreases from the bottom end to the top end of the pole in each layer.

Title: Drawing installation for a press
Inventor: BAUR SIEGFRIED
IPC: B21D24/08
Filed: 1987-11-26
Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE   A drawing installation for a press which has to produce the holding force for the counter-holding during the drawing.  The drawing ram displaces the sheet metal part and the sheet metal holder against the holding force to be produced by the drawing installation and must additionally overcome the inertia forces which occur as a result of the acceleration of the parts of the drawing installation at the beginning of the deformation of the sheet metal part.  In order to avoid the forces which occur thereby impact-like, the piston rod transmitting the holding force is pre-accelerated in the drawing direction prior to the contact of the drawing ram on the sheet metal holder.  The piston rod has an operating surface adapted to be acted upon in the drawing direction.  The pressure space coordinated to the operating surface is adapted to be connected with a pressure quantity space of a pre-acceleration cylinder and with a reservoir by way of a follow-up control.  The control with respect to time of the pre-acceleration cylinder and of the refill from the reservoir takes place in dependence on the movement of the drawing ram, controlled by the press.  The drawing installation is utilizable in presses with mechanically driven drawing ram and a sheet metal holder holding the sheet metal part.

Title: Photosensitive calcium chelators
Inventor: TSIEN ROGER Y
IPC: C07D317/50
Filed: 1988-05-03
Granted: 1992-03-31
Abstract: NEW PHOTOSENSITIVE CALCIUM CHELATORS               ABSTRACT The present invention discloses a new class of calcium chelating compounds which have a decreased affinity for calcium following illumination.  These new compounds contain a photolabile nitrobenzyl derivative coupled to a tetracarboxylate Ca2+ chelating parent compound having the octacoordinate chelating groups characteristic of EGTA or BAPTA.  However unlike EGTA or BAPTA-like compounds, in which the two halves of the chelator are linked by a simple 1,2-ethanediyl moiety, the compounds of the present invention modify the stereochemical conformation of this linkage by adding bulky substituents or incorporating the linkage into a carbocyclic or heterocyclic ring.  In a first form, the new compounds are comprised of a BAPTA-like chelator coupled to a single 2-nitrobenzyl derivative, which in turn is a photochemical precursor of a 2-nitrosobenzophenone.    In a second form, the new compounds are comprised of a BAPTA-like chelator coupled to two 2-nitrobenzyl derivatives, themselves photochemical precursor  of the related 2-nitrosobenzophenones.

Abstract: ABSTRACT      A freezing device is designed as a substantially closed container. The top side of the container has a feed opening (16) and a discharge opening. These ope-nings are located above a maximum level of a cooling medium in the container, which cooling medium in the gaseous state is heavier than air. A first tube extends through an additional opening in the top side of the container and forms an overflow. By means of this device, the level of the cooling medium is maintained constant in the container and excess cooling medium is removed by means of a second tube (32) and a pipe (36) connected to it.
