Title: Procede de fabrication d'articles composites ou encapsules
IPC: B29L31/34
Filed: 1984-09-04
Granted: 1990-01-24
Abstract: Procédé de moulage d'articles composites ou d'encapsulation d'un article selon lequel un article à encapsuler ou à mouler et une résine thermodurcissable et thermopolymérisable sont chargés dans la cavité d'un moule qui a été préchauffé à la température de polymérisation de la résine. Ensuite, on fait le vide dans le moule jusqu'à une pression subatmosphérique pour exposer le moule à un vide de manière à imprégner l'article avec la résine et à dégazer le contenu du moule. Le vide est ensuite libéré pour faire éclater les éventuelles boules de gaz restant dans le contenu du moule. Une pression suratmosphérique est ensuite appliquée au contenu du moule pour que la résine encapsule l'article. Les conditions de température et de pression suratmosphérique sont maintenues pendant un temps suffisamment long pour polymériser partiellement la résine et former une structure unitaire qui est ensuite démoulée. La structure éjectée du moule est soumise à un cycle de chauffage ultérieur pour polymériser entièrement la résine. Des articles composites ainsi formés sont utiles comme structures, guides d'ondes d'antennes, et pour des applications spatiales. Des composants électriques encapsulés par le procédé de la présente invention possèdent une couche de passivation de haute fiabilité.

Abstract: A photographic enlarger or copying machine for colour prints, with a measurement device to determine the density of a test copy, which is exposed with the enlarger by means of a reference specimen selected for testing the equipment. Light guides (15) convey light from the copying light source of the enlarger into a measurement plane outside the copying beam path, which takes the copies to be measured; a photoelectric measurement recorder (25) receives light reflected from the test copy. Depending on a difference in density between the test copy and a reference copy, the correction to the exposure valves are determined in such a way that a copy which is exposed under the new exposure conditions displays the density values of the reference copy.

Abstract: A connector of the nut-and-bolt type with a bolt that has an external thread and/or a nut that has an internal thread. The connector has a locking device that provides a moment of friction that counteracts the unscrewing moment. The pitch of the external thread differs from that of the internal thread. The external thread is screwed far enough into the internal thread or vice versa for the moment of friction of the locking device to result, once the flank clearance between the two threads has been completely occupied and exceeded, from the forces that occur during resilient deformation.

Title: Apparatus for raising and tipping or for tipping a receptacle, especially a refuse receptacle, to discharge its contents into a collecting container
IPC: B65F3/04
Filed: 1987-11-04
Granted: 1991-03-13
Abstract: The device comprises an essentially triangular gripping and supporting plate 12 for the container 55. It can be improved for reliably holding the container 55 to the extent that the gripping and supporting plate 12 is connected with limited mobility, by means of at least one hinge arrangement 36 having associated restoring means and blocking means, to a gripping arm 37 in such a way that when the gripping arm 37 is moved into its normal starting position for the discharging process, the gripping and supporting plate 12 is also brought into a fixed normal starting position for the discharging process with respect to the gripping arm 37 and is blocked in this position. For this purpose, the gripping and supporting plate 12 can, on the one hand, be movably connected to a transverse carrier 21a, 21b, for example via an articulated lever and restoring spring, and be guided for example by means of a cam arrangement for a simultaneous vertical displacement relative to the transverse carrier and a swinging movement towards and away from the said carrier, to be precise in such a way that, in the unloaded state, the gripping and supporting plate has its tip directed opposite to the container to be received and upon lowering into the normal starting position for the discharging process is swivelled towards the transverse carrier. On the other hand, instead of or in addition to this, a transverse carrier 21a, 21b which carries the gripping and supporting plate 12 can be attached to the gripping arm 37 via a bracket which can be rotated in a limited manner about a vertical axis, in order to make the gripping and supporting plate 12 swivellable with respect to the gripping arm 37 and give it limited forward and rearward mobility so as thus to avoid shocks when the gripping and supporting plate is brought up to a container. This limited mobility has particular importance for the receiving and discharging of large containers or smaller containers standing next to one another. For this purpose, the transverse carrier 21a, 21b can be mounted in the manner of a two- armed lever on the bracket 36 and carry a gripping and supporting plate 12 on each lever arm.

Abstract: Covering a rigid but pliable, smooth surface with a one-sided matte embossed polyethylene film, where the non-embossed smooth side of the film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when a drop of water is placed between two sheets of glass. The embossed side of the film forms microscopic air pockets when rolled upon itself which prevents blocking. This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.
