Abstract: Starting from a synthesis process for ammonia in which converter parts heated in the process by the hot gas are cooled by colder gas, a solution is provided which in particular makes possible thinner-walled components and/or less expensive material for the converters and other components. According to the process, this is achieved by repeatedly recirculating the process gas over the ammonia converter(s), separating the ammonia at the end of a cooling space as condensate and passing the fresh gas as cooling gas in the area of hot process gases without contacting the latter. The device having at least one converter and one heat exchanger is distinguished in that a second converter (3) is additionally provided essentially in a parallel arrangement to the first converter (2) with an intermediate steam generator (4) as a heat exchanger in the floor area of both converters (2, 3), a fresh gas supply being arranged as a cooling gas supply in an antechamber (12) of the heat exchanger (4) and a twin pipe connection (11) to the first converter being provided for rinsing a hot gas pipe (9) coming from the first converter (2). <IMAGE>

Abstract: Es wird ein Verfahren und ein Ofen zur Gewinnung von Kupfer aus oxidischen und/oder silikatischen Kupfererzen auf pyrometallurgischem Weg beschrieben. Das Verfahren besteht darin, daß in einer durch Plasmastrahlen erhitzten Reaktionszone, die auf einer Temperatur von mindestens 1500°C gehalten wird, die Kupfererze niedergeschmolzen werden. Bei der hohen Temperatur in der Reaktionszone findet ein thermischer Zerfall der oxidischen bzw. silikatischen Kupferverbindungen statt, wogegen ein solcher Zerfall von Begleitmetalloxiden nicht stattfindet. Die Reaktionszone bzw. der Reaktionsofen ist gegenüber der Atmosphäre abgedichtet, um den Zutritt von Sauerstoff zu verhindern. Als Plasmagas wird ein inertes Gas, vorzugsweise Argon, verwendet. Der Ofen besitzt eine feuerfeste Auskleidung aus kohlenstofffreiem Material, bestehend aus einem Dauerfutter und einem Verschleißfutter aus Feuerbeton.

Abstract: L'inefficacité de la section d'extraction de l'azote d'une installation de distillation d'air produisant de l'oxygène de grande pureté est réduite. Ceci permet une meilleure récupération de l'argon sousproduit et dans certains cas une meilleure récupération du travail de réfrigération également. L'amélioration est obtenue par évaporation du liquide d'un bouilleur avec condensation de la vapeur de rectification d'argon dans deux étages séquentiels pour produire des courants de vapeur ayant une teneur en O2 respectivement supérieure et inférieure à celle du liquide du bouilleur, et on les achemine séparément à la colonne d'extraction de N2. L'amélioration s'applique tant au procédé à pression double qu'au procédé à pression triple. En référence à la Figure (I), le liquide du bouilleur est amené via la vanne (11) au sommet du contacteur (18), et le condenseur de reflux de tête (13) du rectificateur d'argon (14) rebout le fond du contacteur (18).

Abstract: In manufacturing a semiconductor structure, a sacrificial oxidation is performed on monocrystalline silicon (40) between introduction of boron (38) into the silicon and subsequent deposition of tungsten (44) on the silicon. The sacrificial oxidation entails growing an oxide (42) from part of the silicon and then removing at least a part of the so-grown oxide to expose the silicon where the tungsten is to be deposited. Use of he sacrificial oxidation substantially reduces tunnel formation during the tungsten deposition.

Abstract: The invention provides a fastener which somewhat resembles a slide fastener but which can be made at least substantially fluid-resistant. It comprises a first component (1), of flexible and resilient material, having an engagement formation having a longitudinal groove (6) and longitudinally spaced mating formations (10), and a second component (2), of similar material, having a rib (16) and longitudinally spaced mating formations (19). The components can be progressively engaged by the introduction of the rib into the groove and the interengagement of the mating formations. The latter prevent significant relative longitudinal movement between the components. Each component can be made by extrusion of a blank followed by the formation of the mating formations by a rotary die (123). The components can be engaged and disengaged by means of a slide (52) like that used in a conventional slide fastener. To prevent the inadvertent disengagement of the components, the component may have longitudinal retaining or locking formations (7,17) and/or interlocking mating formations (10,19). Numerous other examples are illustrated.

Abstract: The composite material, consisting of a thermosetting resin, reinforcing fibres and a filler, contained in a hollow cylinder (1) is, in the first instance, compacted by means of a piston (2) movable in the said cylinder until a predetermined level of compacting is obtained. At the end of the compacting phase, the position of the piston (2) is referenced by means of a position sensor (15). The compacted composite material is then injected into a mould (13) by giving the piston (2), from its position referenced at the end of the compacting phase, a displacement corresponding to the injection into the mould (13) of the quantity of composite material strictly required for making the moulded part. Thus wasting of composite material is avoided. <IMAGE>

(b) analyz­
ing the predicted secondary structure to determine if either or both of the AUG initiation codon and the 
Shine-Dalgarno 
sequence is contained in a double stranded portion of a stem-loop region of the predicted secondary structure; 
(c) calculat­
ing a free energy value for the stem-loop region; and (d) if the calculated free energy value is in the range 
of from zero to 
about -10.0 kcal/mole, modifying the DNA sequence for the mRNA so that when the modified sequence is 
transcribed it 
produces a modified mRNA sequence which has a predicted secondary structure wherein the AUG initiation 
codon and 
the Shine-Dalgarno sequence are not included in a double stranded portion of a stem-loop region of the 
predicted secon­
dary structure. By means of this method, ten-fold increases in protein production have been achieved.

Abstract: A process for preparing a T-gate (24) utilizes four layers (32, 34, 36, 38) of resist material on a substrate 
(12), which 
typically includes the remaining components of a field effect transistor. The first three layers (32, 34, 36) on the 
substrate 
(12) are photosensitive to deep ultraviolet light, while the fourth (38) or top layer is photosensitive to mid-range 
ultraviolet 
light. A narrow slitlike opening (42) is first formed through the top layer (38) by exposing with mid-range 
ultraviolet light 
and developing the exposed region. A pattern is formed in the three underlying layers (32, 34, 36) by exposure 
with deep 
ultraviolet light, using this opening (42) in the top layer (38) as a mask, and an opening (46) through the three 
underlying 
layers is formed by sequentially developing the pattern. The width of the opening (46) in the layer (32) 
contacting the sub­
strate (12) is narrower than the width of the slit (42) in the top layer (38), but somewhat wider in the other two 
underlying 
layers (34, 36). Upon metallizing this structure and lifting off the metallization, the resulting T-gate (24) has a 
short gate 
length but a massive head (30) to reduce parasitic resistance losses.

Abstract: A concentric tube ozonator which is designed from theoretical considerations to produce ozone efficiently with minimum electrical power consumption. Concentric tube assemblies in the ozonator are designed for ease of construction and replacement of the components thereof, with each concentric tube assembly providing for the relatively precise positioning of the components therein as is required for proper and efficient operation of the ozonator. Each concentric tube assembly is constructed with an outer tubular metal electrode and an inner tubular metal electrode positioned concentrically within the outer tubular electrode. A glass dielectric tube is positioned concentrically and centrally between the outer and inner tubular electrodes. This construction provides an inner concentric annular electrical field discharge gqp between the glass dielectric tube and the inner tubular electrode, and an outer concentric annular electric discharge gap between the glass dielectric tube and the outer tubular electrode, in which the feed gas is converted into ozone. The efficiency of the ozonator is optimized by constructing the ozonator such that the inner and outer annular discharge gaps are maintained in the range of .45 mm to .55 mm, preferably at .5 mm, to provide a minimum discharge gap to convert oxygen to ozone to minimize the voltages required during operation thereof.
