Title: Procédé et dispositif de combustion de schistes bitumineux humides à faible pouvoir calorifique
Inventor: QUESNEL GUY
IPC: F23K1/00
Filed: 1982-06-01
Abstract: Procédé de combustion de schistes bitumineux humides dans une chambre de combustion (24), où ils sont broyés (6) en présence d'un gaz chaud de séchage, les grains broyés les plus gros sont criblés (17A, 17B) pour en séparer et recycler la fraction la plus grossière, puis introduits dans de l'air primaire (25A, 258) dans la chambre de combustion (24). Après le broyage le gaz chaud et les grains broyés passent dans une chambre de détente (8), d'où les grains les plus fins sont entraînés (9) par le gaz de séchage vers des filtres (10), puis réunis aux grains relativement plus gros criblés. Le gaz de séchage est un mélange en proportions dosées de gaz chauds prélevés à la chambre de combustion (24) et de fumées refroidies prélevées à l'entrée de la cheminée.

Abstract: An L-aspartyl-L-phenylalanine lower alkyl ester of which the amino group of the aspartyl residue is protected with a formyl group can be deformylated under selected conditions, i.e. in a strong acid, having a specific normality range at a specific elevated temperature range, and the splitting of the formyl group from the aspartyl moiety amino group can be effected selectively and efficiently in a short time (e.g. as short as 15 seconds to 60 minutes), while the splitting of the ester bond or the peptide bond is suppressed. The deformylation is useful in the production of a-L-aspartyl-L-phenylalanine methyl ester, a dipeptide sweetener.

Abstract: The invention provides a method of and apparatus for preparing a substantially uniform thermoplastic foam extruded from an extruder, the molten thermoplastic resin having uniformly distributed therein a foaming agent. A cooling-mixer (3) receives the extruded mass of resin and foaming agent from a supply extruder (1) and intimately mixes and substantially cools the mass. A substantially adiabatic zigzag mixer (5) is connected to the cooling-mixer and divides the mass into a plurality of separate streams which are at least partially separated and recombined. A die (61) is connected to the zigzag mixer and extrudes the uniformly cooled mass into a lower pressure zone to produce a substantially uniform thermoplastic foam.

Abstract: The disclosure is directed to an apparatus and method for analyzing gem specimens. In the disclosed embodiment, a small cabinet (12) includes a source discharge lamp (21) for radiating electromagnetic energy over a broad spectrum of wavelengths. A gem specimen (G) is placed in a small drawer (19) that, upon closure, becomes an optically sealed chamber in communication with the radiation source (21). Also upon closure, a mechanical shutter mechanism (58-62) permits registration between the radiation source (21), gem specimen (G) and a photocell detector (71) that senses radiation emitted from the gem specimen (G) as a result of its interaction with the spectrum of wavelengths from the radiation source (21). This interaction comprises the combined processes of transmission of and absorption by the gem specimen of the source radiation, internal reflection and internal excitation (e.g., fluorescence), the latter of which produces a frequency shift to a narrow spectrum of energy which the photocell detector (71) is specifically designed to sense. The output of the photocell detector (71) is an analog signal that is processed by electronic circuitry (Figures 11-16) in one of two manners. First, the signal is digitized through an analog to digital converter (91) and is displayed as a numerical digital readout (96). In the second manner, the analog signal is compared with one or more groups of reference values corresponding to different species of gems. If the analog signal falls within a first arbitrary range of values, it is determined to be "natural". In a second arbitrary range, it is determined to be "synthetic". A third range falls between the first and second ranges, and a value within this range is indicative of a gem of indeterminate origin or an operational malfunction. Another group of reference values is used to determine either of two abnormal conditions; viz., a blockage of radiated energy to the detector or the absence of a gem from the specimen holder. The apparatus readout comprises a liquid crystal display (Figure 17) that selectively indicates the mode of operation, the natural, synthetic or indeterminate nature of the gem specimen, and a digital readout of a unitless, arbitrary number which may be used to determine gem quality.

Abstract: Polyamines containing from 0.19 to 20.3 wt % primary amino groups are produced by hydrolyzing in a single stage an isocyanate with an excess of water, a relatively weak basic compound and a water-miscible polar solvent at a temperature from 50 DEG  to 165 DEG C. The hydrolysis is conducted in a manner such that the reactants are substantially homogeneous during the reaction. The isocyanate should have an NCO-content of from 0.5 to 40 wt %. The weakly basic compound may be a carbonate or hydrogen carbonate of an alkali metal or an alkali or alkaline earth salt of a monocarboxylic or polycarboxylic acid or mixtures of such materials. The polyamines produced by this process are particularly useful in the production of polyurethanes.

Abstract: @ An integral wood veneer strip 10 having first, second 62 and third 64 portions with the second portion disposed at less than 180° to the first portion and the third portion disposed at less than 180° to the second portion is produced simply and easily. A number of similarly shaped thin strips of wood 11, with adhesive 12 between them, are placed together to form a linear laminate. Before curing of the adhesive, the laminate is placed in contact with a particularly contoured female die surface 25, with a flexible band 13 over the laminate. A male die surface provides a pressing force at a central portion of the band to press the laminate into close conformance with the female die surface, and the ends of the band are attached up to roller 17, 18. The rollers are rotated to tighten the ends of the band, also bringing the ends of the laminate into tight contact with the female die surface. The adhesive is cured while the laminate is in the bent position (the curing may be facilitated by using microwaves from source 57), and then the laminate is released after curing, and may be utilized as decorative molding for furniture 66.

Abstract: The application relates to a mould assembly (10) including a plurality of individual moulds. Presently such assemblies are made by joining smaller wax patterns together and coating the assembly with ceramic. The layered structure of the ceramic produced by this process can cause flaking and parts of the assembly cannot be replaced if one is faulty. In addition, for casting directionally solidified parts ceramics of greater refractoriness are required. 
<??>The mould assembly (10) of the present application is made by separately transfer moulding a starter base (16), a plurality of moulds (12), a downpole (14) and pouring cup (19), providing each with mechanical locking features, such as screw threads, and joining them together into the assembly. Much greater flexibility is thereby achieved in materials and wall thicknesses which can be different in different parts of the assembly to suit strength and heat transfer requirement, individual bits can be replaced, and the transfer moulding produces a compact homogeneous ceramic structure.

Abstract: Recent proposals to use multiple solid state amplifiers to energise different elements of an antenna array are accompanied by problems in providing the required amplitude control at the individual elements. 
     This can be improved by having twelve antenna elements (2) driven from a common line (1) from which is taken a signal at line (3). This is passed via phase shifters (9 and 10) and identical amplifiers (11 and 121 to a hybrid (13). One output of this is transmitted via phase shifters (19 and 20) to another hybrid (21). The outputs of the hybrids are used to power three antenna elements (2A,2B and 2C). A similar process is applied to signals taken from lines (4,5 and 6). 
     By adjusting the phase shifters (9,10,19 and 20), the required control can be obtained over the power distribution across the antenna aperture.
