Patent EP-0237840-B1 (EP)
IPC: F16H48/30
Filed: 1987-02-24
Granted: 1990-12-12
Abstract: A control device for a friction clutch of a lockable differential for motor vehicles is described, in which, in the power flow from a longitudinally movable control element to a pressure plate 14, a power increasing element is arranged on the clutch 11 which is housed inside the differential housing 3, which power increasing element acts on a pressure piece which loads the pressure plate 14. In order to be able to engage and retain the clutch 11 with the aid of a relatively weak, physically small electromagnet, the power increasing element and a plurality of rocker arms 15a forming the pressure piece interact in the manner of a bell crank. In this way, the axial force required to close the clutch 11 can be generated by a relatively small control force to be applied by the electromagnet. <IMAGE>

IPC: H01L21/316
Filed: 1987-12-08
Granted: 1991-10-30
Abstract: A method of producing a defined arsenic doping in silicon semiconductor substrates is provided. Preferably, the arsenic doping is produced in the sidewalls and floors of trenches having high aspect ratio which are etched into the substrates. An arseno-silicate glass layer is deposited into these trenches to be used as a diffusion source, the glass layer being removed after the diffusion. The arseno-silicate glass layer is deposited by thermal decomposition from the vapor phase of tetraethylortho silicate Si)OC2H5)4 and triethylarsenate AsO(OC2H5)3. A steep and reproducible doping profile having constant, maximum penetration depth and high arsenic concentration in the substrate surface which is needed for VLSI semiconductor circuits is obtained through the process of the present invention.

Filed: 1988-08-31
Granted: 1994-03-23
Abstract: The corrosion damage, particularly that due to local pitting, which occurs on hard-drawn copper tubes used in the sanitary sector is generally caused by carbon-containing films but also by oxide films. A carbon film on the inside of the tube is formed, for example, if the drawing compound added when drawing the tube is subjected to excessive heat. To avoid these damaging films and to improve the pitting resistance of hard tubes made of copper or copper-based alloys, the tubes are first of all degreased. In a further process step, the inner surface of the tubes is then treated with a blasting abrasive in order to establish a minimum roughness. A mean roughness of 0.8 to 1.0  mu m has proven particularly advantageous. The hard-drawn tubes treated by the method according to the invention have none of the films which promote pitting, even after brazing and/or hot bending.

Abstract: FIGs. 3A-3F illustrate a method in a radio communications system of measuring signal quality from a remote unit having a voice operated transmitter (VOX) to execute a handoff of the remote unit. The signal quality of a signal received from the remote unit at a fixed station is measured (422, 424, 426, 428, 452, 454, 456, 458) to determine whether a handoff is to be conducted based upon said signal quality of the signal received from the remote unit. If so required, a handoff request is then sent from the fixed station to at least one surrounding fixed station. In response thereto, an audit request is transmitted (438) to the remote unit from said fixed station. In response to said audit request, a response signal (503) is transmitted at the remote unit for a predetermined period of time. A measurement of signal quality of said response signal is made (454, 456, 458) from said remote unit after said audit request transmission at the at least one surrounding fixed station. The remote unit is then handed-off from the fixed station to the at least one surrounding fixed station. <IMAGE>   <IMAGE>   <IMAGE>   <IMAGE>   <IMAGE>   <IMAGE>

Abstract: The torque-absorbing support consists essentially of four identical rings (10), of rectangular cross-section, in a coaxial arrangement. The two inner rings (10b) are rigidly connected to each other by a hollow shaft (16). The two outer rings (10a) are screwed tightly, one to the fixed machine housing (1a) and on the other hand to the gearbox housing (2a). In each case one inner and one outer ring are elastically connected in a rotationally fixed manner by an intermediate bearing consisting of spring straps (13), arranged in the form of a polygon, which are in each case screwed, parallel to the axis, with one end to one ring (10a) and with the other end to the other ring (10b). This results in the reaction torque of the machine housing being absorbed without lateral forces. <IMAGE>

Abstract: Glass is made from a feed consisting of batch materials and cullet in a furnace that is both electrically and gas fired. A batch-only hopper (1) discharges through a blanket conveyor (2) to a batch melting chamber (16) that is electrically fired and is connected via a submerged throat (6) to a fritting chamber (17) where the at least partly molten batch materials are mixed with cullet fed from cullet-only hoppers (10) by blanket feeders (9). The fritting chamber (17) is fired by a combination of electricity and roof-mounted flat flame burners (11). Material passes from the fritting chamber (17) to a secondary reheating and refining chamber (19) which is heated by regenerative gas burners (13). The separation of batch materials from cullet and separate melting thereof in a pre-melter (16) means that the feed to the secondary refining and conditioning chamber (19) is relatively free of fines and requirement to melt only cullet in the fritting chamber (17) and secondary refining chamber (19) enables those chambers to be operated at a lower temperature than the batch melting chamber (16). The resulting furnace makes efficient use of gaseous combustion and electrical energy and has low emissions of fines and oxides of nitrogen.

Abstract: Afin de réduire les oxydes d'azote contenus dans les gaz de fumée d'une installation de combustion, on introduit dans le courant de gaz de fumée de l'ammoniac liquide frais, c'est-à-dire une solution ammoniacale aqueuse (NH3), ce qui fait que pour atteindre un degré élevé d'élimination des oxydes d'azote, il faut ajouter une quantité sur-st÷chiométrique d'ammoniac (NH3). Dans une installation de lavage humide (6), l'ammoniac en excès (NH3) est éliminé en grande partie par lavage. On ajoute à l'eau de lavage, dans une conduite (10) de raccordement avec une colonne de stripage (11), une lessive alcaline, par exemple du lait de chaux (Ca(OH)2), afin d'obtenir un pH supérieur à 9,5. L'ammoniac physiquement dissous (NH3) est alors désorbé de l'eau de lavage dans la colonne de stripage (11). Le mélange de vapeur d'eau et d'ammoniac qui sort de la colonne de stripage (11) est condensé dans un condenseur (17) et le condensat sous forme d'ammoniac liquide est ajouté à l'ammoniac liquide frais dans la conduite (3). On peut ainsi économiser entre 10 et 50 % environ d'ammoniac liquide frais, selon le degré de réduction des oxydes d'azote.
