Patent EP-0255451-A1 (EP)
Inventor: SAVAJOLS ARMAND
IPC: C25C1/12
Filed: 1987-06-22
Abstract: The present invention concerns a process for stopping for a prolonged period and restarting a series of tanks for the electrolytic refining of copper. The process comprises preparing for the stoppage by reducing the proportion of Cu2+ ions in the electrolyte, controlling the additive agents, regulating the level of the electrolyte, and slow crystallization of CuSO4 in the form of very fine crystals. Subsequent restarting comprises restoration of the circulation of the electrolyte with progressive heating, a progressive increase in the electrolysis current strength, and resumption of the addition of additives. Use of the invention makes it possible to obtain deposits of refined copper of commercial quality as from the first electrolysis cycle.

Abstract: in an optical disk device in which signals can be reproduced from both surfaces of the optical disk or signals can be recorded onto both surfaces of the disk, a pickup (31) that is to be correctly moved along the radial line of a disk is mounted on a support base (30) to which conveyer means is connected. The support base (30) moves while being guided by a U-shaped guide mechanism (5) which is correctly placed in position with respect to a chassis on which a disk drive motor is mounted. The guide mechanism (5) consists of a pair of linear motion guide portions that are arranged in parallel with each other with the rotating surface of the disk sandwiched therebetween, and arcuate guide portions that connect the two linear motion guide portions. When the signals are to be recorded or reproduced, the pickup (31) correctly moves reciprocally on the radial line of the disk along said linear motion guide portions. When the reproducing position is to be changed from one surface to the other surface of the disk, the pickup (31) rises quickly along said arcuate guide portions.

Abstract: Les agencements décrits permettent de générer un faisceau d'ondes progressives bien défini et non affecté par une dispersion par diffraction. Dans différents modes de réalisation, le faisceau peut être une onde électromagnétique, un faisceau longitudinal tel qu'un faisceau acoustique, ou tout type de faisceau auquel peut s'appliquer l'équation d'onde généralisée de Helmholtz. Conformément à la présente invention, un faisceau est généré en ayant une dépendance transversale d'une fonction Bessel, et une dépendance longitudinale qui est entièrement sous la forme d'un vecteur de mise en phase, ce qui donne comme résultat un faisceau ayant une profondeur de champ qui n'est pas affecté par une dispersion par diffraction. Dans des premier et second modes de réalisation, respectivement, un faisceau optique et un faisceau acoustique sont générés en plaçant une source de faisceaux annulaires (30, 40) dans un plan conjugué sur le plan focal de moyens de focalisation (32, 42), ce qui a comme résultat la formation d'un faisceau bien défini (38', 44') parce que la configuration d'intensité du champ éloigné d'un objet est sa transformée de Fourier, et la transformée de Fourier d'une telle forme annulaire est une fonction circulaire.

Abstract: A machine for forming large cylindrical bales of hay is provided, at the inlet (60) to its baling chamber (58), with a pick-up (74) which extends substantially beyond the sides (16, 18) of the machine. There is an auger (76, 78) at either end of the pick-up to feed crop inwardly to the inlet (60). Thus the arrangement can pick crop up from a windrow wider than the inlet (60). 
     In order to prevent wrapping of crop round the augers (76, 78) and the breakage of brittle crop which tends to cause plugging , the augers (76, 78) have scrapers (84, 86) which (in plan view) are disposed so as to diverge from the axis of their associated auger in the direction of feeding of the crop by the auger. In this way the crop pursues a smooth path (106) to the inlet (60).

Abstract: Honeycomb bodies for cleaning the exhaust gases of internal combustion engines function as carrier for a wash coat impregnated with a noble metal. The known honeycomb bodies exhibit square conduit cross sections with a cross-sectional area of approximately 1.1x1.1 mm2. The small cross sections result in high flow resistances which are amplified even more by deposits of rather thick layers of wash coat in the corner areas. A considerable diminution of the flow resistances is achieved without reducing the amounts of harmful substances converted while saving honeycomb material if the honeycomb bodies (1) comprise individual conduits (2) which exhibit a ratio of width (3) to height (4) of 1.5 to 15.

Abstract: A method for forming a high density body from a powder material of metallic and non-metallic compositions and combinations thereof comprising confining a quantity of the powder material in a compressible and expandable mold structure, subjecting the powder material in the mold structure to a predetermined pressure along one axis which confining the material against movement in directions normal to the axis so as to form a compacted body of the powder material and subsequently heating the compacted body to a predetermined temperature so as to further compact the body. A quantity of glass is heated so that it will flow and transmit pressure following which the heated body is immersed in the heated glass and the flowable glass is subjected to a pressure high enough to further compact the body. The resulting densified body is uniformly compressed in the directions of three mutually perpendicular axes extending through the body. The apparatus for forming the body includes a tubular member formed of foam material which is compressible in an axial direction and expandable inwardly in a radial direction so as to densify the powder material contained therein as a result of conventional piston and cylinder action in which the tubular member is contained within the cylinder and subjected to the action of the piston on one end.

Abstract: A low wear contact system, which allow for numerous insertions and withdrawals, comprises a female terminal (4) which has resilient members (16,18) having contact sections (30) provided proximate an end thereof. Wing means (36) are provided at the free end of the resilient members (16,18), such that as the terminal (4) is mated with the matable terminal (2), the wing means cooperate with the terminal (2) to force the resilient members to move apart. This motion insures that contact sections (30) of the resilient members will not slidably engage the contact areas of the matable terminal (2) as insertion occurs, thereby insuring that only minimal wear is effected on the contact areas of the terminals.
