Patent EP-0326303-A1 (EP)
Inventor: BRUNEA ROBERT W
IPC: B41M5/165
Filed: 1989-01-23
Abstract: Method for preventing or reducing the likelihood of successful alteration of information printed on a document, wherein a detectable substance is released from ruptured microcapsules onto the document in image areas. The substance penetrates through the document to form a confirming image on the reverse surface. Another detectable substance of lesser penetrating ability simultaneously may be released onto the document in the image areas. Spreading of the first substance outside the boundaries of the image area created by the second substance may produce a halo effect around the image area. Documents as treated by the methods are disclosed, as well as articles comprising a document to be treated in contact with a sheet coated with the detectable substance. The first substance is microencapsulated, the second substance may or may not be microencapsulated.

Patent EP-0325558-A1 (EP)
Inventor: AMREIN JURG DR
IPC: B07C5/34
Filed: 1989-01-04
Abstract: The bodies drop through a space (5) between a radiation source (11) and a horizontal series of radiation receivers (7), for example phototransistors. The output signals of the radiation receivers (7) for each body dropping through the space (5) are read into a memory. After the passage of the body, the memory contains a data matrix for the body which indicates the perviousness to radiation of the body over its entire surface. A processor calculates from the stored values the average perviousness to radiation, the homogeneity of the perviousness to radiation and the size of the body. These calculated values are then compared with values stored in a table. As a function of the results of the comparison, the processor produces a decision signal which indicates whether the body is to be considered as a body which is pervious to radiation or as a foreign body. If the body is to be considered as a foreign body, the decision signal can actuate a separating device (17). The invention is particularly suitable for separating foreign bodies from a stream of old glass pieces which are to be re-used (molten). <IMAGE>

Abstract: Maleic anhydride is produced by the catalytic vapor phase partial oxidation of a nonaromatic hydrocarbon having at least four carbon atoms in a straight chain with molecular oxygen or a molecular oxygen-containing gas in the presence of phosphorus-vanadium mixed oxide oxidation catalyst. The catalyst is diluted with an inert solid material in an amount sufficient to form a catalyst-inert solid material composition effective to stabilize the maleic anhydride yield such that the average yield decay is less than 0.30% of the established initial maleic anhydride yield per month over an extended period of sustained operations.

Abstract: Les moteurs diesel actuels dotés d'ensembles à pistons en aluminium sont limités à des pressions de chambre de combustion d'approximativement 12.410 kPa (1.800 psi), tandis que les efforts de recherche ont pour objectif d'augmenter ces pressions jusqu'à une plage de 15.170 kPa (2.200 psi). Afin d'atteindre ces niveaux l'ensemble à piston (76) de l'invention comprend un élément de piston (78) en acier ayant une partie cylindrique supérieure (96) d'un diamètre ''D'' et une hauteur de compression ''CH''. Le rapport entre la hauteur de compression ''CH'' et le diamètre ''D'' étant situé dans la plage comprise entre 60 % et 45 %. Ledit élément de piston (78) est de préférence forgé puis usiné à des dimensions pouvant être commandées avec précision. De plus, l'ensemble à piston (78) est de préférence du type articulé et comprend une jupe (80) de piston en aluminium forgé, reliée à l'élément de piston (78) par l'intermédiaire d'un maneton commun (82). Les constructeurs de moteurs cherchent également à réduire la taille du moteur tout en maintenant la puissance, ainsi qu'à améliorer la consommation de carburant et à réduire les émissions. L'élément de piston (76) de l'invention constitue une solution simple et économique satisfaisant la relation entre la puissance accrue et une taille réduite. Afin de produire un ensemble de moteur de taille réduite, ledit élément de piston (78) a un rapport entre la hauteur de compression et le diamètre maximum situé dans la plage comprise entre 60 % et 45 %. Ledit élément de piston (78) est de préférence en acier forgé afin d'assurer une porosité réduite par rapport à celle des pièces coulées standard existantes.

Abstract: Un dispositif de mesure du couple d'une pièce mécanique en rotation comprend un élément de torsion formé d'une roue à rayons (11). Les rayons (16) sont reliés à des premier et deuxième manchons (22 et 27) pourvus de fentes longitudinales (23, 28) dans le sens axial. Un troisième manchon (25) assujetti au moyeu (17) de la roue à rayons (23, 28) est agencé entre les deux autres manchons (22, 27) et se déplace par rapport à ceux-ci (22, 27). Lors de la flexion des rayons (16) qui servent de barres de flexion, les manchons (22, 25, 27) se déforment les uns par rapport aux autres, modifiant l'impédance de bobines (35, 37) traversées par un courant alternatif de haute fréquence, selon le principe dit des courants de Foucault. Le signal de mesure ainsi généré dépend du couple d'entrée. L'utilisation de ce dispositif de mesure est particulièrement avantageuse dans des aides directionnelles électromotrices de véhicules à moteur.

Abstract: The sales package for sewing needles consists of a bearing plate (11) which has a folding edge (17) for bending the upper plate portion in the region of the level of a holder for the sewing needles. A covering sheet (10), formed from transparent film material, is attached to the bearing plate permanently by its lower sheet part but detachably in the upper region in order to be able to remove the sewing needles from the holder. In order to achieve convenient handling of the package, it is proposed that an area (23) with an undulating profile be provided in the covering sheet and/or in the bearing plate, which area is bounded in the manner of a frame by flat adjoining edge surface zones (24, 24', 25, 25'). Sheaths for accommodating the needles individually are produced between the wave crests of this profiled area. Only the regions (24, 24'), situated below the folding edge, of the edge surface zones of the covering sheet and of the bearing plate are connected to one another and form a dimensionally stable closed semi-frame while the other edge surface zones (25, 25') lie only loosely adjacently.

Of the respectively circular paths of the receiving places (8) and of the pressure elements (14, 15), that of the pressure elements (14, 15) is smaller in diameter and arranged inclined in relation to the receiving places (8) in such a manner that the lifting movement of the pressure elements (14, 15), which is necessary for the pressing process, results directly from the inclined circular path. At the same time, as a result of the inclination of the circular path which is smaller in diameter, its projection onto the circular path which is greater in diameter is enlarged and the desired adaptation of the circular paths is achieved. …<IMAGE>…
