Abstract: A hydrotreating process comprises contacting a substantially liquid hydrocarbon-containing feed stream, which contains compounds of sulfur and metals (preferably Ni and/or V), in the presence of a fixed catalyst bed comprising (a) at least one layer of impregnated substantially spherical alumina-containing particles which have been prepared by a process comprising the steps of impregnating specific starting material with at least one dissolved magnesium compound and then heating the thus impregnated material at abut 500-900°C for improved crush strength retention. In a preferred embodiment, the fixed catalyst bed further comprises at least one layer (b) of catalyst particles comprising a refractory inorganic carrier and at least one hydrogenation promoter. A composition of matter comprising the impregnated, spherical alumina-containing particles described above, and a process for preparing them are also provided.

Abstract: To manufacture a compact setting-up device, stationary plates (1) are arranged approximately parallel to the setting-up surface of the skittles (2) with formation of chambers (3). Arranged in the core region of the plates (1) are cord pulleys (5) which extend into the region of the chambers (3) formed and are connected in each case to a cord (6). The cord (6) is wound up in one direction of rotation undertaken via a drive (16, 29, 32) to raise the attached skittles (2) and in the other direction of rotation to lower and set up the skittles (2). At the same time, a free cord loop (15) is placed on each plate (1) in the direction of rotation for setting up the skittles (2). <IMAGE>

Abstract: Although the previously known processes for the preparation of styrene polymers by suspension polymerisation allow a certain amount of control of the particle size, the distribution curve is, however, always relatively broad, i.e. the proportion of oversize and/or undersize particles is still too high. 
<??>It is proposed to add from 50 to 500 ppm, based on the aqueous phase, of carbonates or bicarbonates to the polymerisation mixture. 
<??>The process gives non-expandable styrene polymers for hard processing or expandable styrene polymers for the production of foams, usually for packaging purposes.

Abstract: An arrangement for suppressing audible noise occurring when audio equipment is switched on and off, in which a first electronic switch is connected to the output of an amplifier that has a negative feedback loop formed between the amplifier output and an inverting input of the amplifier. The output of the amplifier is connected to a load impedance through the first electronic switch. A second electronic switch is connected to a junction between the load impedance and the first electronic switch, and to the inverting input of the amplifier. A joint control line permits the two electronic switches to be turned on and off simultaneously. The two electronic switches can be connected in parallel through a feedback resistor in the negative feedback loop.

Title: Improved rim repair process for mis-shapen car wheel drillings.
Inventor: MARKELJ ZLATKO
IPC: B23K9/02
Filed: 1987-11-24
Abstract: Process and corresponding apparatus, in the form of a swing frame for centring and securing the plate-shaped head (101) during repairs to mis-shapen rim drillings. The process involves making circular cutouts in the crown of the straight section (102) of the plate-shaped head, carrying out peripheral conical shaping on both sides and making the new crown plate (109). The rim is then centred and secured by support elements (13) to the swing frame by means of a conical pusher (27) clamped to the thread shoulder (2). The new crown plate is secured between the section support and the plate-shaped pusher before welding. Said support and pusher are height-adjusted on the thread shoulder. The rim is centred and clamped in a tilted position to the frame with a shortened thread shoulder. End welding, grinding to tolerances, making of holes and conical hole reaming may be carried out on the tilted frame or on the shortened thread shoulder frame, according to the rim position. In the positions envisaged, the rim is always secured centrally, the rim repair thus allowing the same properties to be achieved as in a new, industrially produced rim.

Abstract: Apparatus for center notching an insulated electrical conductor includes two pairs of cutting blades that circumferentially slice the insulation at predetermined locations along the insulated electrical conductor to thereby define a slug of insulation. A jaw with a knife edge is located in each of the four quadrants about the insulated electrical conductor axis. The jaws travel in respective rectangular paths in a four stroke cycle. During the first stroke the jaws are translated toward a first plane passing longitudinally through the insulated electrical conductor axis with the knife edges in a separated configuration. During the second stroke the jaws translate toward a second plane perpendicular to the first plane to close the jaws and cause the knife edges to longitudinally penetrate the insulation slug. During the third stroke the jaws are translated away from the first plane with the knife edges in the closed configuration to thereby strip the insulation slug from the conductor. During the fourth stroke the jaws translate away from the second plane to return the knife edges to the open configuration.

Abstract: A plant growth bed (10) for growing plants includes a bag (20) formed of a relatively thin plastic sheet material impervious to passage of liquids and air therethrough with a relatively high loft bedding of crimped textile fibers (31) substantially filling the bag (20). The major portion of crimped textile fibers (31) are hydrophobic staple fibers and the remaining minor portion of the crimped textile fibers (31) are hydrophilic fibers intermixed or blended together. The high loft of the textile fibers (31) provides open spaces (32) around the fibers (31) to allow for optimum air for proper root development and plant growth. The bedding is readily compressible as for compact shipment to about 1/5 the thickness of the uncompressed high loft bedding. In an uncompressed condition the bedding has an overall thickness of at least about 3 inches and a density of 0.5 to 2 pounds per cubic foot. The bedding of fibers (31) has the ability to retain amongst the fibers (31) forming the bedding at least about four times its weight of a liquid (25).

Abstract: L'invention concerne les postes téléphoniques numériques, et plus particulièrement ceux qui sont à écoute amplifiée et les téléphones mains libres. Pour réaliser la fonction d'antilarsen nécessaire dans ces téléphones, on a besoin d'un détecteur d'enveloppe de signal qui fournit une mesure du niveau moyen du signal émis ou reçu sur la ligne. Selon l'invention, on se sert du cofidec présent dans les téléphones numériques pour établir une détection d'enveloppe avec compression logarithmique. Cela évite de faire une détection logarithmique sur le signal analogique de parole, détection qui nécessiterait des diodes tête-bêche pratiquement réalisables seulement en technologie bipolaire. Un convertisseur série/parallèle (S/P), un comparateur numérique (COMP), et un compteur (CNT) ayant une fréquence de décomptage beaucoup plus lente que la fréquence de comptage, réalisent la fonction de détection d'enveloppe de signal.
