Abstract: The invention relates to a process for the preparation of polyglycerols (containing more than 50% by weight of diglycerol), which are low in cyclic components, by reaction of chlorohydrins. In this process,  alpha -monochlorohydrin and epichlorohydrin are reacted at temperatures of 20 to 120 DEG C, preferably of 50 DEG C to 100 DEG C, in a molar ratio of epichlorohydrin to  alpha -monochlorohydrin of 0.8:1 to 1:2.5 in the presence of acids or acid-reacting compounds and an alkaline-reacting medium, preferably an alkaline-reacting aqueous solution, is added to the unseparated reaction mixture obtained at a temperature of 50 DEG C to 120 DEG C, preferably of 80 DEG C to 95 DEG C, corresponding to the content in the reaction mixture of organically bound chlorine. The reaction mixture is desalted after addition of water by means of one or more cation exchangers and subsequently using anion exchangers, water is removed by distillation and the diglycerol/polyglycerol mixture (containing a proportion of glycerol) is separated into diglycerol, higher polyglycerols and optionally glycerol by fractional distillation.

Abstract: A method and apparatus for automatically controlling the depth of earth grading for utilization with a grader or paver (30,180) is disclosed. The method includes determination of time taken for an acoustic pulse to travel from a transducer to a reference surface and back, with this value being used to calibrate a microprocessor-controlled distance-measuring device (100). As the grader moves over a surface to be graded, the distance to the reference surface is constantly detected by a repeated emission and detection of such acoustic pulses. The timing of the echoed pulses is converted to addresses in a look-up table which contains control words symbolizing commands to be given to hydraulic rams (50,60) carried by the grader. By implementing these commands, the depth of the blade (40) relative to the reference surface is constantly updated, compensating for variations with the height of the reference surface. A thermistor is provided to automatically compensate for temperature variations as the grading takes place. Displays are provided for the operator of the vehicle to show what type of adjustments are being made to the blade, and whether the height of the reference surface is outside the range of sensitivity of the follower. The follower is automatically calibrated for a given blade depth by repeated incrementation of a delay time variable until a zero adjustment command is generated for the blade control.

Abstract: A compiler for generating code for enabling multiple processors to process programs in parallel. The code enables the multiple processor system to operate in the following manner: one interation of an outer loop in a set of nested loops is assigned to each processor. If the outer loop contains more iterations than processor in the system, the processors are initially assigned an earlier iteration, and the remaining iterations are assigned to the processor one as they finish their earlier iterations. Each processor runs the inner loop iterations serially. In order to enforce dependencies in the loops, each processor reports its progress in its iterations of the inner loop to the processor executing the succeeding outer loop iteration and the waits until the processor computing the preceding outer loop is ahead or behind in processing its inner loop iteration by an amount which guarantees that dependencies will be enforced.

Abstract: Des constituants et appareils dentaires n'imprimant aucun effort ou passifs possèdent non seulement une rigidité et une résistance accrues mais également des caractéristiques mécaniques généralement supérieures à celles présentées par les polymères de qualité dentaire couramment utilisés. Ils sont également plus esthétiques et plus faciles à mettre en oeuvre, à former et à ajuster que les alliages métalliques à usage dentaire, permettant ainsi des configurations supérieures et exceptionnelles. Les appareils dentaires ou constituants structuraux passifs sont fabriqués à partir d'un matériau composite efficace armé de fibres, constitué essentiellement d'une matrice polymère et d'un constituant fibreux noyé dans la matrice. Le constituant fibreux du matériau composite représente plus de 20 % en poids de ce dernier et le module d'élasticité du composite est supérieur à 0,5 x 106 psi. On produit les constituants passifs en mélangeant initialement un matériau composite efficace armé de fibres présentant les caractéristiques de rigidité, de résistance et l'orientation des fibres nécessaires, en procédant au mouillage sans bulles des fibres et ensuite au formage du composite pour réaliser le dispositif dentaire, afin d'obtenir une esthétique améliorée alliée à une facilité de mise en oeuvre et à une stabilité structurale.

Abstract: Digital image data is encoded using a variable-length code which is described by a group of parameter values. Each parameter value describes a set of code values; each code value corresponds to a possible value of the data which is to be encoded. When the data is encoded, the parameter values are appended to the encoded data. A decoder stores the parameter values into a memory and then combines data values derived from the encoded data with parameter values from the memory to generate decoded data values. Each code word includes a prefix which indicates a number of successive parameter values which are to be summed, and a population index which is to be added to the summed parameter values to produce a decoded data value.

Abstract: The invention relates to the purification and characterization of growth stimulatory and inhibitory protein factors produced by various organs which appear to play a role in the successful formation of metastatic colonies of tumor cells. In particular, it has been found that syngeneic organs secrete protein growth stimulatory and inhibitory factors which can, at low concentrations, affect metastatic tumor cells. The ability of a malignant cell to respond to these factors is believed to be related to tumor cell metastasis to specific body organs. In particular a lung growth stimulatory glycoprotein having a molecular weight of approximately 66,000 daltons has been found to stimulate growth of lung-metastatic rat and human mammary tumor cells in serum deprived medium.

Abstract: Afin de commander un embrayage qui forme un embrayage de pontage (WK) d'une unité hydrodynamique ou un embrayage de changement de vitesses (K) dans une transmission entre un moteur d'entraînement (M) et un engrenage de changement de vitesse (G) d'un véhicule à moteur, on prévoit des dispositifs qui déterminent la vitesse de rotation du moteur (n-M) et la vitesse de rotation à la sortie de l'engrenage (n-ab), ainsi qu'un dispositif régulateur du glissement (1) qui détermine la pression exercée sur un entraînement de réglage (3) de l'embrayage (K) ou de l'embrayage de pontage (WK). Les déviations par rapport à la règle déterminées sur la base de la comparaison (par le comparateur 4) entre des valeurs prédéterminées prescrites du glissement (w) et les valeurs du glissement (s) déduites des vitesses de rotation sont converties en pression par le régulateur (6) selon un algorithme prédéterminé de réglage. La vitesse de rotation à la sortie de l'embrayage (n-K, n-WK) nécessaire pour déterminer le glissement est obtenue à partir du degré de multiplication des vitesses (G-x) et de la vitesse de rotation à la sortie de l'engrenage (n-ab). Pendant le changement de vitese (t-0 à t-3), on détermine une vitesse de rotation virtuelle à la sortie de l'embrayage (n-Kvir) qui sert à assurer la régulation du glissement, ou on fait varier la pression exercée sur l'entraînement de réglage (3) de l'embrayage (K, WK) en fonction de paramètres prédéterminés.

Abstract: A compressed gas container for spraying liquid from an essentially pressureless, compressable product receptacle which is enclosed by an elastically prestressed hollow cylinder made of elastomeric material. The hollow cylinder is able to expand in one direction only and is acted upon by a pressurized gas provided in a clearance space between the product receptacle and the hollow cylinder. The clearance space is hermetically sealed to the outside and is filled, while the product receptacle is empty, with the pressurized gas having a pressure of approximately Pmin. The liquid to be sprayed is fed into the product receptacle in such an amount that the gas contained in the free space reaches a pressure of approximately Pmax. The pressure of the gas in the free space varies, as a function of the amount of product in the product receptacle, between the minimum pressure Pmin and the maximum pressure Pmax.

Abstract: An aggregated-Group Ib metal colloid is prepared, which may be used to form stable color-differentiated images, by the selective application of thermal energy thereto. The metal aggregates, when exposed to thermal energy, revert either to the unaggregated metal or to an aggregate of lesser dimension. This change induces a color change in the material, which is clearly visible against those areas not so exposed. The metal aggregates, when dispersed in a polymeric matrix, are stable in the absence of heat.

Abstract: A washer is described for cleaning the interiors of tanks that hold milk, beer, chemicals and so on. A main body 2 reciprocates relative to a substantially surrounded and relatively fixed piston 19. The body 2 oscillatably supports three nozzles 7 each of which is movable through an arc of 60 DEG  and which arc is angularly spaced from those corresponding to the other two nozzles 7 by further angles of 60 DEG . However, the body 2 and nozzles 7 are also indexed, during operation, in steps, around a further axis which is perpendicular to the axis of oscillation and which substantially corresponds to the longitudinal axis of the tank washer itself. Thus, each nozzle 7 cleans not only on arc of 60 DEG  but rotates that arc through 360 DEG  so that the whole of the interior of a tank is both washed and subsequently rinsed by the three nozzles 7.
