Abstract: A mold for forming a synthetic resin tray (20) to be used in molding chocolate bars comprises a female mold portion (32) defining a mold cavity (34) and a male mold portion (36) including a skirt (42) projecting into the cavity. A plate (50) is disposed in the male mold portion and engages an inwardly extending lip (48) at the free end of the skirt. The plate is provided on a side facing the mold cavity with an inscription and is pressed against the lip by a pressure block (56) disposed in the male mold portion. The pressure block is shiftable to enable a substitution of another inscription plate. The inscription plate may be provided with a projection (100, 174) on the inscription side for forming an opening (80') or a recess (80'') in the injection molded tray.

Abstract: Un système de réduction du bruit servant à améliorer des signaux vocaux perturbés effectue une décomposition spectrale sur le signal, fait passer chaque composant spectral à travers un étage non linéaire qui atténue progressivement les composants spectraux d'intensité inférieure (bruit sans corrélation) tout en laissant passer les composants spectraux d'intensité supérieure (signaux vocaux avec corrélation) en ne les atténuant relativement pas, puis reconstitue le signal. Des blocs de signaux perturbés sont transformés en domaine de fréquence par un dispositif à transformation accélérée de Fourier (dispositif FFT) (1), avec fenêtrage (1a). Chaque bloc transformé est ensuite traité (2) pour présenter une caractéristique de transfert non linéaire, dont la courbe est linéaire au-dessus d'une région coudée à courbe douce, dont la pente change au-dessous de cette région et qui est transformée à nouveau en un signal de domaine temporel reconstitué avec réduction du bruit par un dispositif à transformation accélérée de Fourier inverse (dispositif IFFT) (3), avec chevauchement (3a). Une commande de niveau (4, 4a) fait correspondre le signal avec cette caractéristique. Dans d'autres modes de réalisation, la caractéristique peut varier entre des bandes de fréquence et peut être appariée à des formants de signaux vocaux par poursuite des formants au moyen d'une technique utilisant des paires de raies spectrales (technique LSP).

Abstract: A process for resistance diffusion junction, which can be accomplished in a short time using simple equipment without exerting thermal influences on base metals to be joined and in which a high junction strength is attained by sufficient diffusion of an insert material provided between the surfaces of the base metals to be joined. The process involves a step of providing an insert material between the junction surfaces of a set of base metals to be joined present in close proximity, a step of melting the insert material between the junction surfaces and expelling excess insert material to form a thin-film insert material liquid phase by resistance heat generated by applying voltage across electrodes provided on the other side of each base metal and an applied pressure, and a step of diffusing the insert material at the junction surfaces. In order to prevent generation of Joule heat from the electrodes, an electroconductive heat-insulating material is provided between at least one of the base metals and the corresponding electrode. In addition, displacement during junction of the base metals is measured to control the pressure and quantity of electricity supplied through the electrodes based on the measured displacement value.

Abstract: A method of automatically adjusting the die thickness is characterized in that an inexpensive lock comprising a general-purpose motor for adjusting the die thickness is employed to adjust the die thickness in a short time and to simultaneously prevent an excessive current from passing through the motor. When a crosshead reaches the lock-up position before the die-touch condition is reached thereby or when the die-touch condition is established in the crosshead position ahead of a position (LO) where the set locking force can be produced, the crosshead is moved back from the position involved (LO). The die thickness adjusting motor is otherwise driven in a direction in which a rear platen is moved back (S14) after the platen is moved forth until the die-touch condition is reached. A servo motor is driven in a direction in which a movable platen is moved forth at the same speed as the rear platen moving back speed obtained by multiplying the overriding value corresponding to the position to which the crosshead has moved by the programmed speed so as to make the crosshead reach the aforementioned position (LO). (S12, S13, S15-S18).

Abstract: In the control linkage of a centrifugal governor of a fuel injection pump (15), the transmission length of the inserted adjusting element (19) between the centrifugal weights (14) and the delivery feed adjustment member (32) is variable, the linking of a switch lever (62) designed as a starting delivery disengaging lever also being influenced at the same time. To this end an actuating element (58), via which a stop bolt (53) connected to the switch lever (62) can be axially displaced, has locking teeth (68) which under the frictional force of a slip spring (36) engages with a counter toothing (69) of a supporting section (44) fitted in the adjusting element (19) so that it cannot rotate, thereby forming a locking device (67). By means of a rotary movement imparted to the actuating element (58) a sensitive self-locking positioning of the switch lever (62) is achieved, isolated from the linking of the control linkage (24) and the centrifugal weights (14), and a precisely adjustable centrifugal governor is created. <IMAGE>

Abstract: Starting from a mixture of at least a hydrophobic polymer and a hydrophilic polymer, these polymers are first dissoved in a suitable solvent or mixture of solvents and subsequently coagulated in a coagulation bath. According to the invention a more or less hydrophilic membrane is prepared by removing the membrane so obtained from the coagulation bath and subsequently by leaching at least a part of the hydrophilic polymer from the matrix, alternatively followed by hydrophobisation. 
     Said leaching of the hydrophilic polymer occurs by treatment of the membrane with an oxidising/hydrolising agent. 
     The invention furthermore comprises microporous membranes, flat or tubular or in the form of hollow fibers, having a good chemical resistance and good mechanical strength.

Abstract: A lightning resistant composite structure, particularly for aircraft, in which a composite skin panel, (10) for example of carbon fibre, is attached to an inner composite structure (11) by one or more lightning resistant fastener assemblies (12). The fastener assembly comprises a nut (21) and bolt (13), the bolt being in good conductive contact with a conductive sleeve (25) engaging the skin panel (10) and a non-conductive sleeve (20) engaging the inner structure (11). The nut is contained within a capped nut assembly (14) located to the undersurface of the inner structure (11). 
     The non-conductive sleeve (20) and the capped nut assembly isolate the inner structure (11) from the effects of lightning strike, the conductive sleeve (25) providing a high quality conductive interface between the bolt and the skin panel. By this means adverse penetration of lightning current into the inner structure is prevented.

Abstract: L'invention concerne une vanne de vidange et une méthode ayant pour objet d'éliminer les produits de condensation et les impuretés dans le réservoir d'air comprimé du système de freinage pneumatique d'un véhicule. Dans un mode d'exécution préféré, la vanne de vidange comprend un piston cylindrique disposé de manière à glisser dans le sens longitudinal à l'intérieur de la cavité d'un corps de vanne conçu pour être monté sur le véhicule et comportant sur sa paroi latérale deux orifices communiquant avec la cavité, d'une part, un orifice d'entrée raccordé en amont au réservoir et, d'autre part, un orifice de sortie raccordé en aval pour faire ofice de système de vidange. La sortie est bloquée dans une première position (position fermée) du piston lorsqu'on déclenche l'allumage du moteur. Lorsqu'on coupe l'allumage, le piston passe de la première position à une deuxième position, de manière à ouvrir simultanément les orifices d'entrée et de sortie dans la cavité pour purger le réservoir. Lorsqu'on déclenche l'allumage, le piston revient à la première position dans la cavité, de manière à fermer la vanne de vidange.
