Patent EP-0456855-A1 (EP)
Inventor: YAMAMOTO KOZO
IPC: A23L1/304
Filed: 1990-05-16
Abstract: A liquid food additive having a relatively high content of calcium. The food additive is produced by mixing in water an ionizable calcium composition having an alkalinity with lactic acid. As the ionizable calcium composition, is preferably used a calcium composition which is produced by heating the powder of shells such that the powder is at least partially decomposed. Also, is preferably used lactic acid which is produced by lactic acid fermentation and purified. The food additive is effectively prepared by the steps of suspending the calcium composition powder in water; mixing the suspension with an aqueous solution of lactic acid; and stirring the mixture until the powder is completely dissolved. A processed foodstuff mixed with the food additive is disclosed.

Abstract: A digital D.C. control system includes a multiplexer (22), a digital-to-analog converter (24), a capacitor (30), offset generating circuitry (26,27,28) and clamping circuitry (33,34 or 42,44,46). A digital signal (from 20) to be D.C. controlled and a digital brightness control signal (from 16) are alternatively coupled by the multiplexer to the input of the digital-to-analog converter. The output from the digital-to-analog converter is coupled to a system output terminal via the capacitor. When the signal is applied to the digital-to-analog converter a fixed D.C. offset is applied to the interconnection of the converter and capacitor. During preselected intervals the D.C. control value is coupled to the digital-to-analog converter concurrently with the system output terminal being clamped (through 33 or 44) to a fixed reference and the D.C. offset circuitry being disabled (at 27). This combination of apparatus permits controlling the D.C. level of a digitally processed signal without affecting the dynamic range of the digital signal.

In elevation, each landing portion will be disposed in vertically spaced horizontal planes, and there will be a medial constant slope ascending or descending portion. Interconnecting each landing portion with the constant slope portion will be entry and exit transitional curved portions of varying slope as seen in the elevational view. To enable the steps to traverse the curved path successfully, the effective length of the outer of the step chains is varied at different points along the path of travel of the escalator.

Abstract: In the method of removing volatile substance according to the present invention, volatile substances formed during the bulk polymerization or solution polymerization are heated in a heating zone divided into a plurality of parts and having a temperature gradient of rising from an inlet of the heating zone toward an outlet thereof to a temperature at which the volatile substances are not substantially gasified in the portion of the heating zone which is on the side of the inlet, and to a gasification temperature in the second to last portions of the heating zone, and the heated substances are subjected to flash distillation in a gas-liquid separating step to separate gas from liquid. According to this method, the heating conditions for a polymerizing liquid, the residence time thereof in the heating step and the timing of the flash distillation can be controlled easily, and the polymerizing liquid as a whole can be heated uniformly and efficiently. Moreover, the temperature of the polymerizing liquid does not become locally higher than required level. The polymerization of a monomer in the polymerizing liquid can be suppressed, and the formation of a polymer of low molecular weight can be minimized. The apparatus for removing volatile substance according to the present invention has a heating zone (5) formed with a multi-tubular heat exchanger (1) having a polymerizing liquid passage and a heating medium passage. The heating medium passage of this heat exchanger (1) is divided into a plurality of heating chamber (5a,5b). This apparatus is suitable for practicing the above-described method according to the present invention.

Abstract: L'invention concerne un procédé d'amélioration de paraffine catalytique à lit fluidisé. En régulant de manière précise la granulométrie des particules catalytiques et leur densité, ainsi que la vitesse de la vapeur superficielle de la matière utilisée, le lit fluidisé est maintenu dans un régime d'écoulement turbulent. De manière surprenante, le maintien du lit fluidisé dans un régime d'écoulement turbulent éloigne la sélectivité du produit du méthane et de l'éthane en la rapprochant vers les produits plus précieux tels que l'hydrogène, des oléfines légères et l'essence C5+. Dans le mode de réalisation le plus préféré, le catalyseur contient un composant métallique de déshydrogénation tel que du gallium, du zinc, du platine ou du rhénium pour obtenir un produit d'essence C5+ riche en substances aromatiques. Des catalyseurs utiles dans le procédé de l'invention comprennent des zéolites tels que des matériaux silicieux en couches.

Title: Phosphine fumigation method and apparatus.
Inventor: WINKS ROBERT GORDON
IPC: A23K3/00
Filed: 1990-06-25
Abstract: Fumigation of grain in a storage facility having a plurality of grain silos (13) is effected from a single source (10) of a mixture of a carrier gas and a gaseous fumigant. The single source is connected to a single gas supply duct (11), to which gas inlet ports (16) of the silos are also connected. The connection between each gas inlet port and the duct is provided with a respective valve (14) and a respective orifice plate (15), which is adjusted so that the pressure drop across the orifice plate into the silo is substantially greater than the pressure drop across any other component between the gas source and the silo. With this arrangement, the flow rate of gaseous fumigant through the grain-containing silos in the facility suffers only a minor perturbation when a valve between the gas supply duct and a silo is opened or closed. This minor perturbation can be readily compensated by returning the gas pressure in the duct to its previous value. <IMAGE>

Title: A building structure, particularly a road bridge structure, and a method of making such a building structure.
Inventor: THYGESEN SOREN
IPC: E01D19/08
Filed: 1990-08-16
Abstract: A building structure, such as a road bridge, has a lower part, e.g. a reinforced concrete beam (2, 3, 4, 8), and an upper part (23, 24) separated from each other by means of a liquid-impermeable membrane (9) which consists of a non-adhesive, low friction sheet material and is formed with hood portions (16) tightly enclosing block-like elements (11) projecting upwards from the upper surface of the lower part (2, 3, 4, 8). The hood-clad elements (11, 16) again fit tightly in recesses formed in the upper part (23, 24). Horizontal forces are transferred from the upper to the lower part via the flanks of the block-like elements (11), thus perpendicularly to the membrane material. In a practical method of making the structure, the block-like elements (11) are first attached to the lower part on top of a full sheet of membrane material, and pre-formed hood portions (16) of the same membrane material are then applied to the block-like elements (11) and sealed to the sheet (9).
