Patent EP-0460331-A1 (EP)
Inventor: DESJOYAUX JEAN LOUIS
IPC: B28B7/34
Filed: 1990-06-05
Abstract: The element is characterised in that it is made from an injectable material which is shaped to delimit a hollow internal impression (1a) corresponding to the dimensions and shapes of the product to be obtained after casting the concrete, constituting a dead mould thereof. In order to allow stacking of the dead moulds and to solve the problem of drying the stacked products, the moulds comprise a peripheral edge (16) formed as a projection and vertical wings (1c). The wings (1c) are supported on the peripheral edge (16) of the mould situated below projecting from the bottom (1a), thus ensuring good circulation of air between the stacked elements. <IMAGE>

Abstract: Procédé de fabrication de papier selon lequel on prépare une charge à l'aide de matière en fibre de cellulose contenant du sulfate de calcium (gypsé), ladite matière étant désintégrée dans un milieu aqueux pour faire partie de la charge permettant de produire le papier. Les traits caractéristiques du procédé sont que (a) des ions de carbonate et/ou des ions de carbonate d'hydrogène (CO32-) ou resp. HCO3-) sont transmis au milieu aqueux, et (b) le pH dans le milieu aqueux est ajusté à une valeur alcaline de sorte que le carbonate de calcium forme un précipité et fasse partie de la suspension. Ledit procédé comporte des avantages généraux considérables dans le contexte d'application de couches de gypse sur le papier, en ce sens que l'on peut réutiliser les déchets sans aucune précipitation gênante du gypse. L'invention concerne en outre une nouvelle qualité de papier enduit, le trait caractéristique de ce papier étant que la charge du papier de base se compose entièrement ou partiellement de carbonate de calcium précipité (CCP), et que le pigment de la couche de revêtement se compose entièrement ou partiellement de sulfate de calcium.

Abstract: A precision sigma-delta A/D converter having a desired number of cascaded stages is disclosed herein. The multi-stage sigma-delta analog-to-digital converter (10) of the present invention is operative to convert an analog input signal X(z) to an output sequence of digital words. The converter (10) of the present invention includes a first sigma-delta converter stage (14) for generating a first sequence of digital words and a quantization error signal in response to the analog input signal X(z). An interstage amplifier (34) then amplifies the quantization error signal by a first gain factor G. The present invention further includes a second sigma-delta converter stage (18) for generating a second sequence of digital words in response to the amplified quantization error signal. The first and second sequences are next filtered by a digital noise cancellation network (31, 32) and the filtered second sequence is divided by the first gain factor G via a divider circuit (38). A summing circuit (40) provides the output sequence of digital words by summing the filtered first sequence and the divided second sequence. The digital noise cancellation network (32) is also used to compensate for errors due to analog component imperfections, e.g., capacitor mismatches and finite operational amplifier gain.

Abstract: A hollow article of polybutylene terephthalate is efficiently obtained by blending and kneading l00 parts by weight of polybutylene terephthalate with 0.0l to 5 parts by weight of an alkoxysilane (selected from vinylalkoxysilanes, epoxyalkoxysilanes, aminoalkoxysilanes, allylalkoxysilanes and mercaptoalkoxysilanes) and blow-molding the blend into a hollow article. The blend may further contain 0.5 to 30 parts by weight of an olefin copolymer of an α-olefin and α,ß-unsaturated glycidyl ester or its graft copolymer on a vinyl (co)polymer. The process prevents parison drawdown and breakage in the course of blowing. The hollow article is improved in respect of uniform wall thickness and appearance and is useful for automobile and car components.

Abstract: A pin-type, double-acting synchronizer mechanism (22) with friction clutches (24,36 and 26,38), jaw clutch (28,14b and 30,16b) and self-energizing ramps. The ramps act between a shaft (12) and a shift flange (32). The shift flange is rotatable relative to the shaft and jaw clutch members 28,30, and defines three sets of self-energizing ramps (32k,32m,32n,32p) which act against three sets of ramps (35c,35d,35e,35f) defined by elongated members (35). Members (35) are fixed against rotational and axial movement relative to the shaft. Three circumferentially spaced pins (40) include blocker shoulders (40c,40d) for preventing asynchronous engagement of the jaw clutches and pre-energizer surfaces (40e,40f) which each cooperate with a pre-energizer and neutral centering assemblies 42. The angles of the self-energizing ramps may be varied to provide substantially the same synchronizing time for several or all of the ratio gears in a multi-ratio transmission.
