Title: Method for protecting a large number of articles during storage and preservation periods, by using the evacuation of air followed by the introduction of an inert gas in a closed cycle
IPC: A23L3/3418
Filed: 1988-12-16
Abstract: The invention relates to a novel method for preserving and protecting a very large number of articles of any type: chemical, medical, dehydrated food products, any type of fabric, paper, antiques and works of art, wood, leather, explosives, cereals and starches, fodder, etc., against oxygen in the air, humidity, insects, rodents, aging, self-explosion, fires, etc. This invention consists in placing the articles to be preserved in hermetically closed preservation chambers from which air has been sucked out as much as possible, then replaced by any inert gas coming from a gas tank joined to the preservation chamber. This inert gas remains mixed with the articles throughout the preservation. In order to add or withdraw articles, the inert gas is first withdrawn from the preservation chamber by means of a pump and compressed into the same above mentioned tank, then air is let in in order to replace the gas, after which the chamber is opened. This method also allows the use of the same quantity of gas an infinite number of times, and in addition does not cause any pollution of the surrounding air.

Title: Procede et appareil pour attenuer la diffusion de gaz a travers une structure
Inventor: GRUMSKI JOSEPH T
IPC: B05D5/00
Filed: 1989-03-28
Abstract: Il est réalisé un procédé et un appareil pour atténuer la diffusion de radon gazeux et de produits de décroissance radioactive à travers une structure 10. La structure 10 est enduite pour former une enveloppe continue 22 qui empêche le gaz de diffuser à travers la structure 10. L'enveloppe 22 est de préférence en mousse de polyuréthane rigide ayant une structure à cellules fermées avec une masse volumique comprise entre 40 et 56 kg/m**3 (2,5 et 3,5 livres/pied cube). Le faible coefficient de vitesse de diffusion dans la masse de la mousse sert à piéger le gaz dans les cellules de la mousse en empêchant le gaz de passer à travers la structure 10. A mesure que le gaz est piégé dans les cellules, il se désintègre en particules solides contenues en permanence dans la structure à cellules fermées de la mousse.

Title: Screw fastener member
IPC: F16B13/02
Filed: 1989-07-03
Abstract: The invention relates to a fastener member which can be installed simply by driving it into a hole, but which can then be screwed or unscrewed. This member is composed of a tubular peg 5 with an external screw thread 12 and of a blocking element 6 having a diameter slightly greater than that of the central passage 11 through the peg. The element 6 has a head 8 similar to that of a screw or of a bolt, a conical tip 7 and a central shank 16 provided with longitudinal ridges. The peg 5 is inserted into a hole 3 bored to the external diameter of the screw thread 12, then the element 6 is placed in the peg, which dilates it radially and embeds the screw thread 12 in the elements 1 and 2 to be assembled. The ridges on the blocking element secure it to the peg in terms of rotation which allows subsequent screwing or unscrewing. Such a member can be used advantageously for assembling panels and other elements, particularly made from reconstituted wood, and in particular facilitates the mechanised assembly of furniture.

Title: Fishing lassoo or fishing hoop
Inventor: PATRICE DERICK
IPC: A01K73/12
Filed: 1990-03-21
Abstract: This is a round fishing net, which is thrown in the fashion of a lassoo or of a hoop, possibly serving as a game on the beach, the net being intended for fishing at the seaside or elsewhere. It is characterised by the method of operation; the retaining cord (1) is attached by its handle to the stop. The shackle (2) is there so as not to entangle the net when throwing it, drawlines (3) are attached to the lower part of the shackle, a grommet (4) spaces its lines apart and locks the swivel to the bottom of the ring (5) through which the drawlines pass and where the net is attached at its centre, the net being of any mesh, the outer circumference of which is formed by a weighted cord (8) and, at the centre of the net, a hoop which is thrown. When it sinks into the water, it draws in the fish and when the cord is pulled, the lines rise from the traps formed by the net, imprisoning the fish. This system is particularly interesting for its sporting throw, beach sport, lassoo fishing.

Title: Connection device forming drain and interceptor for the evacuation of waste water of sanitary apparatuses
Inventor: RONDA ROBERT
IPC: E03C1/29
Filed: 1991-02-12
Abstract: The invention related to drain, interceptor and practical parts concerns the installation and connection for the draining of waste waters. The mounting is carried out by simple pressure of joints (5) housed in grooves (4) of neck (3) which slides on the male pipe (1) of the drain. The securing is done either manually by means of the knurled screw or with a screw driver. All drawings show that the characteristics of each drain element are identical. Those of drawings (1; 2 et 3) represent the most common parts: drains, interceptors and pratical parts. The drain pipe (1) has a diameter slightly smaller than that of neck (3) of interceptor (2). Its length is variable. The interceptor neck is reinforced due to the presence of semi-circle grooves which receive O-rings (5). The latter will provide for the perfect tightness of the assembly. The passage or ''play''(6), of interceptors or siphons, as a diameter sufficient to allow the pipe (1) to be housed therein. The screw (8) is provided with a knurl which will facilitate the installation or disassembly by hand. Said knurl may also be provided with a slit at its middle point to provide for the utilization of a screw driver. The holes (9) have a diameter corresponding to screws tapped to mechanical pitch. The diameter of tube (7) corresponds to the standards in force. Its length varies with the model. The sleeve (10) (figure 1), as well as the connection parts (figures 2 and 3) have the same references as those of interceptor (2).
