Abstract: In a new process for the preparation of a supported catalyst for the polymerisation of  alpha -olefins, first a support gel (1) is prepared by introducing a sodium water glass or potassium water glass solution into a swirling stream of an aqueous mineral acid optionally containing aluminium ions longitudinally and tangentially to the stream, spraying the resultant silicic acid hydrosol in drop form into a gaseous medium, and allowing it to solidify to form a hydrogel, and freeing the resultant hydrogel, without prior ageing, from salts by washing and optionally from some of the water by extraction with alcohols and/or ketones, and then drying the hydrogel. This gives the support gel (1), which is ground and fractionated according to particle size. In a second process step, the support gel (1) is charged with chromium trioxide or with a chromium compound which can be converted into chromium trioxide, after which the resultant chromium-containing support gel (2) is heated at from 400 to 1100 DEG C for from 10 to 1000 minutes in an anhydrous gas stream containing oxygen in a concentration greater than 10% by volume. It is essential for the process according to the invention that the drying of the hydrogel to form the support gel (1) takes place in a high-speed drier within a maximum time of 300 seconds at an inlet temperature of from 200 to 600 DEG C. The supported catalyst prepared in this way gives homopolymers and copolymers of ethylene having excellent low-temperature toughness.

Abstract: In the case of a compensator (1) for the electrical connection of two parts of an electrical high-voltage switching installation, two mutually opposite tulip contacts (2, 3) are provided with sprung contact laminates (9) which hold a conductor element (6) between them. The conductor element (6) produces the electrical connection between the tulip contacts (2, 3) and, if necessary, compensates for any offset of the tulip contacts (2, 3) with respect to one another at right angles to their connecting axis. Such an offset can arise, for example, as a result of thermal expansions of busbars, or as a result of production and assembly tolerances. <IMAGE>

Abstract: The invention relates to a method for measuring the concentration of a heavier gas of low concentration in a gas stream which comprises said gas and a lighter gas of high concentration, using a gas detector. The invention comprises     setting the gas stream into rotation, separating the stream into a first fraction enriched with the heavier gas and into a second fraction depleted of the heavier gas,   supplying the first fraction to the measuring point and   subsequently recombining the two fractions.   In this manner it is possible to measure very low concentrations of the heavier gas in the gas mixture. <IMAGE>

Abstract: An inner surface shaper comprising, on a bed (10), a first reciprocating stock (1) having a first working spindle (2) and a drive screw (8) aligned with each other; a first reciprocating drive (5) having a servomotor (4) to drive said drive screw for making a linear reciprocating motion of said first reciprocating stock (1); a second reciprocating stock (17) having a second working spindle (21) in opposite relation with said first working spindle; a second reciprocating drive (20) having a hydraulic cylinder (15) to drive said second reciprocating stock (17) toward and apart from said first reciprocating stock (1); and a tool rest placed between said first working spindle (2) and said second working spindle (21) to permit a tool to cut and shape the inner surface of a workpiece, said first reciprocating stock (1) and said second reciprocating stock (17) being arranged and movably fixed to said bed (10) with said first working spindle (2), said second working spindle (21), said drive screw and said hydraulic cylinder arranged along the centre line of said bed; said hydraulic cylinder and said first reciprocating stock being connected by two joint rods (141, 14b) which are arranged symmetrically with respect to the centre line of said bed. 
     This arrangement has the effect of directing undesired counter force to the joint rods (14a, 14b) and the longitudinal axis of the drive screw. Thus, there is no fear of causing any distortion as would bend either working spindle or would injure the threads of the drive screw.

Abstract: Particles of glass or silica type material are added to pellets of gas generating material as the gas generating material is being loaded into the combustion chamber of a gas generator or inflator (10). When the inflator is fired, the liquids and gases produced by the resulting rapid combustion process are cooled and condensed by the particles of glass or silica type material to a solid inside the combustion chamber near the exit ports or outlet holes (38, 40, 42) thereof. This dramatically reduces the amount of combustible particle residue or particulates that leave the inflator.

Abstract: Buffer lines and corresponding buffer tags and buffer valid/dirty registers in conjunction with buffer control circuit are provided to a DMA controller enabling the DMA controller to conditionally pre-fetch data from memory while data being read are transferred from the DMA controller to the I/O device during read operations and to conditionally write data back to memory while data being written are transferred from the I/O device to the DMA controller during write operations, thereby improving asynchronous read/write throughputs. Read requests, random as well as sequential, are satisfied with pre-fetched data if they are validly stored. Write requests, random as well as sequential, are deferred, batched and optimized. The improved throughput is achieved in a manner completely transparent to system software.

Abstract: On a découvert que le 8-exo-formyl-2,6-exo-tricyclo[5.2.1.02,6]décane présentant la constitution et la stéréochimie de la formule (I) possède des propriétés olfactives particulièrement utiles qui sont nettement supérieures à celles des 8-endo-épimères et qui se font déjà bien sentir si le composé (I) est enrichi avec des mélanges de 8-exo/endo-épimères. Le composé (I) peut donc s'utiliser avantageusement, sous forme pure ou enrichie, comme matière odorante ou comme constituant de compositions de parfum. Pour fabriquer un mélange d'épimère enrichi, un mélange obtenu de manière connue (US-PS 3 270 061) et présentant un rapport exo/endo de 1,45:1 est amené en équilibre par catalyse basique, de préférence par l'action d'hydroxides alcalins dans une solution alcoolique, afin de donner un rapport exo/endo de 5,25:1. En variante, le mélange d'épimère enrichi peut être préparé à partir de 8-formyl-2,6-exo-tricyclo[5.2.1.02,6]décène-3(4), soumis à une hydrogénation catalytique par exemple avec du charbon palladeux et ensuite éventuellement amené en équilibre. Ou bien du 2,6-exo-tricyclo[5.2.1.02,6]décène-8 peut être hydroformylé et éventuellement encore amené en équilibre. Pour préparer le composé pur (I), de préférence un mélange de 8-exo/endo-épimères obtenu de manière connue en soi est réduit en un mélange d'alcools correspondant, à partir duquel le méthylol à configuration 8-exo est isolé par chromatographie ou distillation et oxydé pour obtenir à nouveau l'aldéhyde (composé I).
