Inventor: COTE PIERRE LUCIEN
IPC: C04B12/00
Filed: 1991-10-22
Abstract: L'invention se rapporte à un nouveau procédé pour enfermer de manière étanche une masse de déchets et qui consiste à: entourer la masse de déchets, de déchets stabilisés ou son côté de positionnement d'au moins une couche pratiquement continue de matériau poreuse, la couche définissant une face de contact pratiquement continue enveloppant les déchets, et à fournir une quantité suffisante d'un réactif interréactif de chaque côté de la face de contact pour que les réactifs, après le positionnement, se diffusent l'un vers l'autre et forment un précipité qui remplit les pores dudit matériau poreux sensiblement le long de ladite face de contact, ce qui produit une couche enveloppant les déchets de perméabilité réduite. L'avantage particulier de ce procédé est que, après une rupture de l'élément d'étanchéité, les réactifs interréactifs créent une nouvelle couche d'étanchéité, ce qui empêche la fuite de substances nocives à travers la fissure.

Abstract: Disclosed is a plasma torch in which the position of the center electrode (1) is adjustable relative to the orifice of the plasma torch (2). The invention is based on a construction in which the center electrode (1) is mounted to the body part (9) of the plasma torch by way of a pivotal ball joint (7, 23), whereby the electrode (1) can be pivotally rotated in said joint (7, 23), thus making it possible to align the electrode tip to the orifice center of the plasma nozzle (2). The spherical element (7) of the pivotal joint is attached to the bearing box (23) with the help of a tightening gland nut (11, 12). The depth of the center electrode (1) can be adjusted by rotating a depth adjustment gland nut (14), which is attached to the spherical element (7) by a threaded joint. Due to its versatile adjustability, the function of the plasma torch can be maintained in a stable range, thus significantly contributing to reduced wear and damage of the plasma nozzles.

Abstract: An accessory (61) for vehicles, such as bicycles, prams, etc, is shown, having a simplified attachment. The attachment consists of a positively engaging lock, the accessory initially being hooked onto the carrier rack, for example of the bicycle, and then locked. The locking takes place in a positively engaging fashion with a bar (62) which engages behind a carrier-rack rod (66). In order to remove the accessory, unlocking takes place independently of the actual process of removal by previously actuating a handle (60) which draws back the bar (62). In order to obtain better matching of the hooks (65), provided on the saddle-bag (61), to the distances between the transverse struts of the carrier racks, the hooks and, if appropriate, also the bar on the accessory, can be moved in the direction of the rod (66) on the carrier rack. <IMAGE>

Abstract: A method for forming interlevel contacts in integrated circuits includes the formation of a titanium nitride layer (26) prior to formation of an overlying conductive layer of a material such as polycrystalline silicon or a metal. In one approach, CVD titanium nitride (26) is deposited over a partially formed integrated circuit device and in a contact opening (20). The titanium nitride layer (26) is then exposed to an atmosphere containing oxygen, so that oxygen atoms diffuse into the titanium nitride layer (26). This may be done in conjunction with an annealing step. In another embodiment, layers of titanium (28) and titanium nitride (30) are sequentially sputtered onto the device. The nitride layer may then be exposed to an oxygen ambient, or the oxygen may be incorporated into the titanium nitride layer during the sputter deposition.

Abstract: This device is applicable to any engine of this type. It comprises an electronic unit (10) associated with an annular gear (12) of the inertial flywheel and with the variable-reluctance sensor (22), such as those used for electronic ignition engines. The instantaneous duration di of passage of the teeth (14-16) is worked out (26-30-32-34). From the signal di, the duration T4 of the fraction of a turn of the flywheel corresponding to one combustion cycle is calculate (36) and stored (38). A magnitude D%4 representing a projection of the varying component of the angular speed of the flywheel at the combustion frequency is also calculated (40-42). A calculation stage (44) combines (T4 and D%4) with constants A and B characteristic of the type of engine in order to produce measurement signals of the mean gas torque for each combustion of the gas mixture in the cylinders of the engine. The invention permits, in particular, optimised adjustments and the detection of combustion misfiring in engines of private or industrial vehicles. <IMAGE>
