Abstract: An extrusion die head (10) for producing multiple layer tubular plastic bodies is disclosed in which the size of the tubular resin flow passage for at least one of the resin layers is infinitely adjustable at the point where two or more resin layers merge together to form a multiple layer stream. The adjustable passages are formed by two spaced inclined surfaces at the downstream end of the passages. The thickness of the passages is varied by axially moving one surface relative to the other. The moveable inclined surface (60) is carried on an annular ring member (62) mounted in the die head (10). In one embodiment, the ring (62) is replaceable with another ring member to axially move the surface, thereby adjusting the layer thickness. In another embodiment, the ring member (62) is threadably mounted in the die head so that rotation of the ring causes axial movement of the surface to adjust layer thickness. In the preferred embodiment the ring member is rotated by a drive mechanism operable from outside the die head for adjustment without disassembly of the die head. Adjustability of the gap sizes in the die head widens the range the relative thicknesses of the layers and widens the range of relative viscosity values that can be used. The versatility and usefulness of the die head is thus increased over that of die heads employing fixed gaps. <IMAGE>

Abstract: Procédé de commande de la fréquence de glissement d'un moteur à induction présentant d'excellentes caractéristiques de réponse. Lors de la détermination d'une fréquence de glissement (Fs) et d'une fréquence de flux excitateur (φ0) en utilisant des éléments matériels, on réduit l'erreur de commande et le retard de commande en déterminant ces deux paramètres par un traitement par logiciel utilisant un processeur de commande vectorielle. A cet effet, dans les sous-programmes de commande de vitesse (101 à 104) on calcule une quantité de glissement (A) et un reste (α), obtenu par l'activité précédente du sous-programme, en divisant par une fréquence de début de sous-programme (CV) la valeur obtenue par l'addition du reste (α') calculé par l'activité précédente du sous-programme et une fréquence de glissement qui est obtenue en divisant le produit d'une instruction de courant secondaire (I2) et une constante proportionnelle (K2) par l'instruction de flux d'excitation (Ζ). Dans le sous-programme de commande de courant (201 à 205) exécuté pendant une période plus courte que celle du sous-programme de commande de vitesse, on calcule des données de distribution de glissement (φ) et un reste (β) actuel en divisant la valeur obtenue par l'addition d'une quantité de glissement à calculer et du reste (β') précédent par le nombre (n) de débuts du sous-programme de commande de courant. En outre, les données (φr) qui représentent la vitesse réelle du moteur sont ajoutées aux données de distribution de glissement calculées, afin d'obtenir une fréquence de flux d'excitation (φ0).

Abstract: A cushioned shipping assembly includes a corrugated carton and foam inserts which are returned by an end user to the fabricator. In some embodiments, the carton collapses to a diminished size for return. The fabricator refurbishes the components, recycling aged or spent pieces. Preferably polyolefin foams, olefin-based adhesives and coatings, and wood fiber-based corrugated material make up the cushioned system, and one component is compatible with recycling processes of others. The fabricator may perform on-premises pelletizing of reclaimed polymer, thus providing a more efficient, environmentally clean system.

Abstract: For supporting of formwork in constructing buildings, use is made of steel post shores (props) having a pin 15 with recessed areas thereon. When the prop has to be brought from the loaded to the unloaded position, such pin is changed of position in the prop so as to allow the inner tube to be lowered within the outer tube of the prop. The invention provides a new pin-design such that after assembling the prop it can be clearly seen wether the pin finds itself in the correct position or not. For that purpose, use is made of a pin (15) having a recess (27) and a flattened portion (29); by axial displacement of the pin this portion rests (in fig.2,10) on ring (12) or on inner tube (3) under changing its angular position, which is well visible for the user. Alternativily the cylindrical pin (35) of fig. 4 has two cams (39, 41) resting on ring 12; by axially displacing this pin, it will rotate over 90 DEG  and the inner tube (3) will be lowered in the outer tube (1), which position is clearly visible for the user. <IMAGE>

Abstract: The present invention relates to a pseudoplastic fluid composition including water, a mixed metal layered hydroxide dispersed in the water to impart preselected rheological properties to the fluid and a fluid loss additive composition including one or more of a carboxymethyl substituted vegetable starch, a carboxymethylated cellulosic compound or mixtures thereof in an amount effective to inhibit loss of fluid and with the degree of substitution being selected so that the carboxymethyl substituted compound is soluble in the fluid at the concentration of use without materially adversely affecting the rheological properties of the fluid and so that the fluid is resistant to fermentation. The improved composition includes a crosslinked carboxymethylated vegetable starch which has a degree of substitution in the broad range from about 0.3 to about 0.8 and in a narrower range of about 0.4 to about 0.7 and an uncrosslinked carboxymethylated vegetable starch or a carboxymethylated cellulosic which has a degree of substitution in the broad range from about 0.3 to about 0.57 and in a narrower range from about 0.4 to about 0.5. The drilling method includes drilling while circulating the drilling fluid with the improved composition therein.

Abstract: Process for the isolation and purification of free acids, starting from their salts, by electrodialysis which involves the use of:   i) an electrolytic cell of four compartments, in which the two compartments adjacent to the two electrodes are separated from the central compartments by means of cationic membranes (2) and the central compartments are separated from one another by means of an anionic membrane (1); or, alternatively, ii) a module formed by an array of cells of 4 compartments separated from one another by alternating anionic membranes and cationic membranes.   By means of this process, the simultaneous presence of the isolated free acids and their salts in the same compartment is prevented, which increases their purity. A large number of acids and amino acids can be isolated and purified. In a preferred embodiment, the purification and isolation of IDA is described. <IMAGE>   <IMAGE>

Abstract: The in vivo chemotherapeutic treatment of cancer cells in a living animal is improved by first administering to the animal an antagonist specific for intracellular histamine in an amount sufficient to inhibit the binding of intracellular histamine in normal cells. An enhanced toxic effect on the cancer cells from the chemotherapeutic agent is obtained while any adverse effect of the chemotherapeutic agent on normal cells is inhibited. In addition, long term continuous administration of the antagonist following administration of the chemotherapeutic agent results in at least amelioration of the adverse side effects of chemotherapy. The treatment of cancer cells using DPPE specifically illustrates the invention.

Abstract: Recombinant host cells are obtained that comprise (A) a heterologous, polypeptide-encoding polynucleotide segment, stably integrated into a chromosome, which is under transcriptional control of an endogenous promoter and (B) a mutation that effects increased expression of the heterologous segment, resulting in enhanced production by the host cells of each polypeptide encoded by that segment, relative to production of each polypeptide by the host cells in the absence of the mutation. The increased expression thus achieved is retained in the absence of conditions that select for cells displaying such increased expression. When the integrated segment comprises, for example, ethanol-production genes from an efficient ethanol producer like Zymomonas mobilis, recombinant Escherichia coli and other enteric bacterial cells within the present invention are capable of converting a wide range of biomass-derived sugars efficiently to ethanol.
