Abstract: Polychloropyridines containing chlorine substituents in the 2, 3, and 6 positions and, optionally, in the 4 and 5 positions, are prepared from polychloro-2,3-lutidines containing at least one chlorine substituent in each methyl group and, optionally, a chlorine substituent in the 6 position by liquid phase chlorination. Lewis acid metal halide catalysts are, optionally, employed. 2,3,5,6-Tetra­chloropyridine is, accordingly, prepared by chlorina­tion at 200 to 260°C in the presence of ferric chloride catalyst of a mixture of polychloro-2,3-lutidines obtained by the vapor phase chlorination of 2,3-­lutidine.

Abstract: A pre-mixed burner fired at or above atmospheric pressure by a gaseous fuel or a fuel that is liquid at ambient temperature or a liquid fuel completely evaporated prior to combustion comprises a mixer wherein the fuel, combustion air and a cooling fluid are blended prior to combustion downstream of a burner plate. The combustion forms a flame at or near the limit of flame stability. The ionization current which is a characteristic property of each flame is measured by two electrodes which transmit signals to a controller controlling the flow of at least one of the fluids flowing to the mixer by corresponding valve actuation for safe burner operation at or near the limit of flame stability.

Abstract: A low temperature phase separation, dephlegmation and distillation process is described for resolving a light hydrocarbon gas stream to recover and purify C₃₊ and/or C₄₊ hydrocarbons. The phase separation bottoms stream is segregated from the dephlegmation bottoms stream and both streams are expanded to produce refrigeration for the feed stream. Both streams are then separately introduced into a distillation column for final purification of the heavy hydrocarbon product.

Abstract: L'utilisateur de l'appareil agit sur des organes de commande solidaires d'un cylindre (6) se déplaçant dans une colonne verticale (1). Un tube fixe (12) pénètre dans le cylindre (6). Un compresseur (16) permet de produire une surpression à l'intérieur du tube (12) et du cylindre (6). Une force antagoniste fonction de la valeur de cette surpression et de la surface de la section du tube (12) s'oppose aux déplacements vers le bas du cylindre (6). Cette force antagoniste est sensiblement constante, le volume de la partie du tube (12) engagée dans l'enceinte (6) étant négligeable par rapport au volume total de cette dernière. Ainsi, contrairement à ce qui est le cas avec les appareils de culture physique de ce type dans lesquels la force antagoniste est produite par un ressort ou par le déplacement d'un piston à l'intérieur d'un cylindre, cette force reste constante tout au cours du déplacement de l'organe mobile sur lequel agit l'utilisateur de l'appareil.

Cette machine supporte de façon rotative une électrode (20) à une distance prédéterminée (d) du centre d'un disque (25) qui effectue un mouvement circulaire rotatif et, en même temps, supporte cette électrode au niveau de sa partie supérieure qui lui sert de point de support, imprimant ainsi à l'arc produit à partir de ladite électrode un mouvement circulaire rotatif grâce à la rotation dudit disque. Selon la présente invention, dans ladite machine, bien que la partie inférieure de l'électrode effectue un mouvement circulaire, l'électrode, elle, ne tourne pas, un courant électrique pouvant ainsi directement alimenter l'électrode.

Abstract: Un commutateur électromagnétique, en particulier pour appareils de démarrage de moteurs à combustion interne, comprend des contacts de courant principal (13, 14) dont les surfaces de contact tournées vers l'axe longitudinal (40) du commutateur présentent des protubérances arrondies (17). Le commutateur comprend également un contact arrondi rotatif à pont (33) ayant une surface de contact (39) qui fait partie d'une calotte arrondie dont le rayon de courbure est inférieur à celui des surfaces arrondies (17) des contacts de courant principal (13, 14). Cette conception des parties de contact (13, 14; 33) diminue la tendance du commutateur à rebondir et à se souder lors de hautes performances, tout en améliorant sa capacité à dissiper la chaleur, étant donné que le contact essentiellement ponctuel se fait toujours lorsque le contact à pont (33) et les contacts de courant principal (13, 14) sont dans la position voulue, grâce entre autres à la possibilité de compenser des variations dimensionnelles.

Abstract: A contact piece (7) which is capable of translatory movement is connected to mutually parallel first spring sheet-metal strips (14), while second strips (11) assigned to the first strips in each case and provided adjacent thereto are immovably fixed. Mutually assigned first and second strips are assembled at the end by cross pieces (13) of the same material and have the same effective lengths. When the contact piece moves, mutually assigned first and second strips are symmetrically spread apart more or less strongly transverse to their flat sides, or are pressed together from an initial spread position. The contact piece is thereby held on a track of travel extending precisely transverse to the beam direction of the optical signals. <IMAGE>

Abstract: In an improved process for the preparation of 1,6-di(N<3>-cyano- N<1>-guanidino)hexane from alkali metal dicyanamide and a hexamethylenediammonium salt in alcoholic solution or suspension, the reaction is carried out in the presence of a limited amount of water and a catalytic amount of a base, preferably a tertiary amine and the pH of the reaction mixture is 8 to 10 at the beginning of the reaction. After the reaction is complete, water is added to the reaction mixture in the heat, above 80 DEG C, and the coarse-crystalline product formed is separated off from the liquid phase. 
<??>Preferably, sodium dicyanamide and hexamethylenediamine dihydrochloride, preferably formed in situ from aqueous 1,6-diaminohexane and aqueous hydrochloric acid, are reacted in n-butanol in the presence of 0.1 to 20% by weight of water, relative to the solvent including water, at a pH of 9-9.5.

Abstract: A nonvolatile static random access memory cell (110) includes a pair of cross-coupled transistors (T1,T2) which function as a bistable circuit to store data states. Variable threshold transistor (M1,M2) are respectively connected in series between the driver transistors (T1,T2) and load devices (R1,R2). A control node (97) is driven to a high voltage state to cause one of the variable threshold transistors (M1,M2) to be driven to have a higher threshold voltage and thereby store the data state held in the cross-coupled transistors (T1,T2). The data state is thus stored in nonvolatile form. Upon recall the memory cell (110) is reactivated and the threshold differential between the variable threshold transistors (111,112) causes the driver transistors (T1,T2) to be set at the stored data state. The data recalled by the memory cell (110) is in true rather than in complementary form.
