Patent GR-3004975-T3 (GR)
IPC: F41A9/72
Filed: 1992-06-18
Abstract: The present invention relates to smooth-bore guns having a tubular magazine and an operating system either semiautomatic indifferently of the inertial type, of the gas intake type or of the recoiling barrel type, or manual pump-operated or convertible from one system to the other, relating essentially to a new cartridge feed system adapted to these types of firearms. The invention comprises a new cartridge descent lever (1) which causes the cartridges (15) to pass from the magazine tube (16) into the barrel (22), either automatically or manually. For the feeding with semiautomatic operation of the firearm, part of the energy of the spring of the hammer (18) of the firearm is used to cause the vertical rotation of the cartridge descent lever (1) so that a cartridge (15) exits from the magazine tube (16). For the feeding with manual pump operation of the firearm, the same movement is caused by the bolt (31) when it opens manually, by means of the cocking rod, for the expulsion of the case in the barrel (22). Finally, for the manual change of the cartridge (15) in the barrel (22) the same movement can be caused by the hand of the shooter which, with the finger which presses the trigger (17), finds, in an easily accessible position, a tab (44) of the cartridge descent lever (1) protruding from the lower level of the body of the firearm. In all the cases described above, the successive passage in the barrel (22) of the cartridge (15), exiting from the magazine tube (16), occurs in a conventional manner for the type of firearm considered. In the various operating systems all the movements of the new cartridge descent lever (1) are in any case synchronized and compatible with the used operation without the need for adjustments.

Title: Conveyor device with a strand of links
Inventor: HAERTEL NORBERT
IPC: B65G35/08
Filed: 1997-06-26
Abstract: A description is given of a conveyor device having a strand of links driven while lying one against the other via end faces (71, 72) and held by means of guide rails, on the opposite sides of which links there are arranged grooves for receiving guide and drive means, which grooves extend in the longitudinal transport direction. A bore (5) passes through the link in the transverse direction for receiving a driver bolt. In order to provide such a link in which, as well as exact guidance of conveyed workpieces, precise positioning under individual processing stations and a good cleaning possibility of the links, heating has no disadvantageous consequences even in heavy-duty operation, it is intended that a metal piece (10) which extends in the longitudinal transport direction is fastened on a link, which has at least one first plastic part (12), in such a manner that the end face (71, 72) of the at least one first plastic part (12) projects beyond the metal piece (10) in the longitudinal transport direction and that the total length of the link is greater than the total length (l) of the metal piece (10). <IMAGE>

Patent GR-3025260-T3 (GR)
Title: Injection-moulded single-edge plastic container with a snap-on lid
Inventor: KEMMERICH HERBERT
IPC: B65D43/06
Filed: 1997-11-05
Abstract: The invention relates to a container characterized in that the interior (14) of the lid (2) when closed lies below the upper edge (3) of the container (1). The inside (15) of the lid edge surrounding the lid interior (14) has a reinforcement bead (16) running round it with a multiplicity of inwards-facing parallelepipedal projections (17) which connect the lid interior (15) to the inside of the lid edge. The outer part (6) of the lid edge running round the outside of the plastic container wall (4) has an ouwards-facing inclined slide surface (10) merging in an approximately vertical zone (11) which is located at a large distance from the container wall (4) and terminates close to the edge (8) running round the container. The aim of the invention is to increase the ability of the containers and their lids to resist damage when they are stacked one on top of the other, thus considerably facilitating the stacking process and avoiding damage to the edge of the lid by adjacent containers during stacking or transport on pallets for instance.

Abstract: A new lens blocking material (adhesive composition 78) is proposed that essentially overcomes the drawbacks of previous blocking materials. This new material combines traditional UV and/or visible light (VIS) curable polymer materials with specially selected filler(s) as a non polymerizing solid in order to achieve or improve certain desirable material properties, including those of low shrinkage, low exothermic heat of polymerization, and improving the ability to deblock, while simultaneously reducing the high cost associated with such UV/VIS radiation curable materials. The new material is being used in methods for blocking a lens blank (54) onto a lens block (62) with a lens mounting face (64) that has a pre-determined block curve, in which the number of different block curves required to cover the full range of standard lenses is minimized.
