Abstract: The spacer possesses carrying legs (1) which are arranged in a first plane and supporting legs (3) which are arranged in another plane, the two planes forming an acute angle. At the junction of the two legs, a web (5) is fastened in order to carry the upper reinforcement mat. Carrying limbs (6) with hooks (7) are arranged in the plane of the supporting legs (3) in order to receive the lower reinforcement mat. In order to increase the stability of the holder when loaded by the lower mat, the supporting legs (3) are bent inwards at the bottom, the bends (10) lying somewhat above the apex (8) of the hooks (7), as a result of which the resulting force acts on the carrying legs (1) in the direction of the bearing surface. To increase the carrying capacity of the hooks (7), the supporting legs (3) and the carrying limbs (6) are connected to one another by a strut (9). Such a spacer exhibits, with the same wire thickness, improved stability and a higher carrying capacity than previously known holders, and additionally facilitates the laying of the upper reinforcement mats. <IMAGE>

tivateur rétroviral et, d'autre part, pourvu d'un marqueur hétérologue placé sous le contrôle du promoteur, en l'occurrence 
le LTR 5′ , normalement associé aux séquences codant pour les protéines  gag, pol  et  env . La présence de rétrovirus infectieux

     Abstract 
     The invention concerns means (products 
and processes) applicable to the  in vitro  detec­
tion of the presence of an infectious retrovirus 
in a biological specimen, in particular of an 
AIDS virus (HIV). These means consist, in par­

tion by HIV and which include a recombinant 
gene containing a DNA corresponding essen­
tially to the totality of the genome of rotrovi­
rus having a gene which can be activated by a 
retroviral transactivator controlled by a promo­
ter. Said DNA, however, does not contain the coding sequence for the retroviral transactivator but does contain a heterol­
ogous marker controlled by a promoter, in this case LTR⁵, which is normally associated with the coding sequences for the 
 gag, pol  and  env  proteins. The activation of the marker indicates the presence of infectious retrovirus in the specimen.

Abstract: Multilevel interconnections for high density integrated circuit devices are described which have reliable low resistivity contacts suitable for sub-­micron semiconductor technologies including NMOS, CMOS and biFET. First level interconnections are achieved by the use of a multilayer metallurgical structure com­prising a first layer of titanium and a second layer of aluminum containing 3.5 to 10 percent copper and an unexpectedly high content of silicon (2.5 to 8.0 per­cent). Second and subsequent levels of interconnection are provided using metallurgy including a first layer of titanium and a second layer of aluminum-copper. Prior to deposition of the second level conductors, multiple cleaning steps in oxygen plasma and hot aqueous chromic-phosphoric acid baths ensure that extremely low resistance contacts are formed in sub-micron contact regions.

Abstract: Protective gas for the heat treatment of metals is frequently produced in generators. This type of production is expensive. It is simpler for producing a protective gas to burn a hydrocarbon- containing fuel gas such as natural gas or propane in a jacketed jet tube. This is not possible, however, if the combustion is to be less than stoichiometric, that is to say a sooty endothermic gas is to be produced with an external heat supply. In order to allow the production of protective gas nevertheless in such cases, the combustion is carried out stoichiometrically and a mixture of nitrogen and methanol is sprayed into the combustion chamber (3). In this case, the combustion temperature should not fall below 750 DEG C. <IMAGE>

Abstract: In a float-actuated control device for changing the flow section of an outlet opening of a compensation basin for regulating the discharge of waste water and/or rainwater, for example of a retention basin, as a function of the height of the liquid level, a throttle slide (12) which can be guided via the outlet opening (3) is motionally connected to a float (14) by means of an articulated lever system (23, 25, 28) actuated via a link control (18, 19). The float (14) is situated in a gas-filled housing (30) which is open solely at its lower side and in which the liquid level is set as a function of the volume of the enclosed gas, which is determined by the pressure corresponding to the height of the liquid level in the container. As a result of the construction of the guiding slot (18) of the link control and also the design, assignment and arrangement of the individual parts (23, 25) and pivots (24, 26, 27) of the articulated lever system, it is possible to obtain a highly uniform discharge characteristic over the entire duration of a rainfall occurrence. <IMAGE>

Abstract: An etching method whereby a sufficiently high etching rate is attained, in a uniform surface treatment that is very gentle on projecting edges of the substrates. Also the substrates are held at or brought to a sufficiently high temperature by the etching process. The method for etching substrates with a magnetic-field supported low-pressure discharge is characterized in that the magnetic field is decoupled from the substrates such that the magnetic field strength at the substrates is less than 6000 A/m. In the space between the substrates and the magnet system at least one electron emitter is disposed at a location at which a magnetic field strength is present that is greater than the field strength at the substrates but equal to or less than 12,000 A/m. On the side of the substrates facing away from the at least one electron emitter, at least one anode is disposed with an anode potential of +10 to +250 V with respect to ground. An etching potential between -100 V and -1000 V with respect to ground is applied to the substrates. The ratio of the gaps between the substrates and the surfaces of the substrates projected onto a projection plane carried through the gaps amounts to at least 0.1. The potential difference between the at least one emitter and the at least one anode is selected so high that an electron current (primary and secondary electrons) flows through the substrate gaps to the anode.

Abstract: A circuit arrangement for detecting the crossings by an applied alternating voltage of two separate threshold levels respectiveiy above and below a fixed reference voltage level comprises: 
the series combination of two resistances(1 and 2) in an electrical path between the applied alternating voltage and the dc reference voltage which includes voltage com­parators (VC1 and VC2) having two possible logic output states to compare the voltage at the junction (P) of the two resistances with the reference voltage (5) so that the logic output state of the comparators at any instant is determined by the voltage at the junction relative to the reference voltage, and logic means (G1) in which the logic output state of the comparators is combined so that a pulse span­ning each instant of cross-over by the applied alternating voltage of the reference voltage is produced thereby having a leading edge and a trailing edge which respectively correspond with the instants of crossing by the applied alternating voltage of the two separate threshold levels. One threshold level is determined by the magnitude of the reference voltage (5) and the other threshold level is determined by the ratio of the resistance values of the two resistances (1 and 2) and the dc supply voltage. A circuit in which a resistor is replaced non-linear network is also described. This circuit is particularly fit for application in an integrated circuit.

Abstract: A technique for assembling semiconductor devices in which semiconductor elements, especially lasers or LEDS, are mounted on a first packaging element such as a heat spreader that is mounted on a second packaging element such as a heat sink. Handling of solder preforms is avoided by coating at least one of each of the pairs of surfaces to be brought into contact with a layer of solder and heating the assembly to melt both solder layers in a single operation. In a preferred embodiment a heat spreader is coated in solder on both sides and interposed between a semiconductor element and a heat sink and the assembly is heated. Molybdenum may be used as a layer to aid wetting and adhesion and gold/tin solder may be used. Slightly different solidification temperatures and compositions for the layers may result from different take up of metallisation layers from the components into the solder.
