Title: Method and apparatus for injection moulding rubber soles having at least two layers
Inventor: DREWINSKI HUBERT
IPC: B29C44/08
Filed: 1993-04-22
Abstract: Process for injection moulding rubber or rubber-mixture soles having at least two layers and connecting them to one another and if required to a shoe upper. First the rubber mixture for the bottom sole layer is injected into an enlarged mould cavity and the latter is made smaller to match the volume of the bottom sole layer; once the rubber mixture has partially solidified the upper delimitation means for the bottom sole layer is removed and is replaced by a last. The rubber mixture for the inner sole layer is infected into the thus created mould cavity. By displacing the bottom sole layer upwards, the mould cavity is made smaller to match the size of the inner sole layer; after partial solidification of the rubber mixture the lower delimitation means of the inner sole layer is lowered by a certain distance and the inner sole is allowed to expand in controlled manner with the mould cavity enlarged. The apparatus according to the invention (Fig. 6) provides an intermediate piece (1) which is arranged between lateral mould parts (16a) and the bottom die (2) and can traverse both horizontally and vertically.

Abstract: SUMMARY:   In this method for the integral manufacture of an internal structure of coach bodies with a self-supporting box structure (18), channels (10) in a ceiling region  and shape-determining insulatiion bodies  (12)  in corner regions are glued together with an inner winding layer (8) shaped and carried by a winding core.   Heating fabrics serving as floor heating and well heating and metal rails extending longitudinally in a base region and in the side wall regions are arranged at the inner winding layer (8).  The unevennesses arising thereby at the surface are levelled out by insulating foam so that a stepless surface arises, which can be wound over and is wound over with an outer winding layer  (16).   After the setting of the resin-irpregnated winding layers (8; 16), the internal structure is removed from the shape-determining winding core and cut open by a longitudinal cut (20) in  the base  region.   After  the  insertion  of  the  elastically deformed internal  structure into the box structure (18), the internal structure is moved upwardly in arrow direction (P2; P3) and sidewards in arrow direction (P4; P5) by means of a tensioning device (24).  In that case, the bands (25) laid  in  between  the  internal  structure  and  the  box  structure  (18)  aredeformed elastically. In a further assembly step, the internal structure is provisionally  screwed  together  with  the  box  structure  (18)  from inside through bores and connected from outside with the base plates (23) by means of screws engaging into the metal rails in the base region.

Inventor: VOGEL HANS-GUENTER
IPC: B03B9/06
Filed: 1993-07-19
Abstract: ABSTRACT            In order to process residual materials that are generated during reconstruction or the removal of roofing materials with bituminous sealing properties, the roofing materials that are stripped off are reduced in a shredder to a size of 6 to 20 mm and the granulate is divided into fractions in a wind sifter.  The light fraction, which contains only insulating materials, is compacted and re-processed into new insulating materials by the manufacturer of such insulating materials.  The heavy, bituminous fraction, which contains at most 5% insulating materials is ground to a grain size of 0.5 to 2.0 mm and has conventional fillers added to it and is then used to manufacture bituminous masses.

Filed: 1993-11-12
Abstract: Lors de l'émission d'un signal audio par multiplexage dans une période synchrone d'un signal vidéo, une mémoire tampon permettant de régler l'axe des temps du signal audio est contrôlée. Le nombre d'échantillons du signal audio en mémoire tampon est détecté pour tous les n champs (n étant un entier positif) du signal vidéo, et lorsqu'il diffère d'une valeur particulière, l'adresse de lecture ou d'écriture de la mémoire tampon est prédéfinie, de sorte que le nombre d'échantillons de signal audio en mémoire tampon est tenu constant au moment de l'inspection pour tous les n champs. De plus, l'inspection du nombre d'échantillons de signal audio en mémoire tampon pour un champ ou plus permet de stocker une ligne contenant une valeur maximale ou minimale du nombre d'échantillons, et ainsi de tenir constant le nombre d'échantillons de signal audio en mémoire tampon pour cette ligne de manière à exploiter efficacement la capacité de la mémoire tampon. Pour rétablir l'isochronie des signaux vidéo et audio, du côté émission, le retard du signal audio par rapport au signal vidéo d'une ligne vidéo prédéterminée est tenu constant, et, du côté réception, le signal vidéo est retardé en fonction du retard du signal audio par rapport au signal vidéo de cette ligne.

Abstract: In a line accommodation circuit for use in combination with a cell exchange apparatus to carry out a conversion operation of a sequence of input data signals into a sequence of asynchronous transfer mode cells sent to the cell exchange apparatus, first and second function systems which are identical in structure with each other are supplied with the input data signals in parallel and are switched from an active system to a standby system by a switching operation indicated by a system controller.      During the switching operation, the active system stops the conversion operation and produces the asynchronous transfer mode cells left therein while the standby system starts the conversion operation to produce a following asynchronous transfer mode cell. A test cell is inserted in the active system after a last one of the asynchronous transfer mode cell held in the active system and placed in the standby system before a following asynchronous transfer mode cell following the last asynchronous transfer mode cell. The test cell is at first detected by the standby system and thereafter detected by the active system. When the test cell is detected by both the active and the standby systems, the next asynchronous transfer mode cells succeeding the following asynchronous transfer mode cell are sent from the standby system which is rendered into a new active system. The active system which interrupts the conversion operation is rendered into a new standby system.

Abstract: Débitmètre massique à effet de Coriolis servant à mesurer le débit massique d'un matériau dans un conduit. Le débimètre présenté peut être monté directement sur un tuyau existant ou un autre conduit sans que l'on ait à dévier le flux de matériau. Le débitmètre comprend un mécanisme (20) tel qu'un dispositif d'attaque magnétostrictif, servant à faire osciller une section du tuyau entre deux support (12, 14). Le dispositif (20) est monté sur un ventre d'ondes ou près d'un ventre d'ondes du second mode d'harmoniques de la fréquence naturelle de la section du tuyau. Un capteur (30) monté à côté dudit dispositif d'attaque est actionné par l'intermédiaire d'un circuit de commande (Fig. 5) pour commander la fréquence d'oscillation de la section du tuyau. Un deuxième capteur (32), tel qu'un accéléromètre, est monté au niveau du noeud du second mode d'harmoniques de la fréquence naturelle de la section du tuyau au moment où le débit est égal à zéro (noeud de débit zéro). Le deuxième capteur mesure l'amplitude du déplacement du noeud de débit zéro due aux forces de l'effet de Coriolis résultant de la masse de matériau s'écoulant à travers le tuyau oscillant. Cette mesure donne une indication du débit massique du matériau s'écoulant à travers le tuyau. Le débitmètre est indépendant de la détection de décalage de phase et il n'est pas sensible au bruit étranger. Ce débitmètre ne nécessite pas en outre un montage compliqué. Dans d'autres modes de réalisation, le débitmètre est préfabriqué sur une section de tuyau qui peut ensuite être installée dans une tuyauterie et constituer un article disponible sur stock. ur image.

Title: Method and Apparatus for Fracturing Connecting Rods and the Like
Inventor: JONES JOEL W
IPC: B23D31/00
Filed: 1994-03-25
Abstract: A process and apparatus for fracturing, into a bearing cap and a connecting rod, an integral preform which defines a cylindrical aperture and two spaced-apart bolt seat shoulders. A guide member defines a first guideway along which moves a first slide member, the latter in turn defining a second guideway parallel to the first, along which a second slide member moves. A split mandrel has an upper part fixed with respect to the first slide member and a lower part fixed with respect to the guide member. The split mandrel halves define an internal taperedpassageway for receiving a wedge capable of forcing the mandrel halves apart. Projections on the second slide member contact the bolt seat shoulders when the cylindrical aperture of the preform receives the split mandrel, and means are provide for urging the second slide member toward the mandrel. When the wedge member enters the tapered passageway, forcing the mandrel parts apart and fracturing the preform, the bearing cap's contact with the projections and the upper part of the split mandrel securely holds the bearing cap in place. Furtherpositional security is provided by static and dynamic locators which have a lateral pinching action on the bearing cap and on the connecting rod.
