Title: Ceramic cutting material reinforced by whiskers
IPC: C04B35/80
Filed: 1989-08-29
Granted: 1993-01-13
Abstract: The present invention relates to a ceramic cutting insert comprising whiskers for chip forming machining of steel and having improved mechanical, thermal and wear properties. The insert comprises besides the oxide based matrix 5-50 % by volume, preferably 10-40 % by volume, of homogeneously dispersed whiskers of a solid solution of nitride and oxide of aluminium preferably of the cubic aluminium oxynitride spinel (AlON). A part of the whiskers may be replaced by whiskers of silicon carbide. The properties of the composite material can be further modified by coating the whisker material with thin layers. The whisker reinforced cutting material shows an improved toughness behaviour.

Abstract: Le processeur d'amélioration de la présente invention comprend un canal gauche (10) et un canal droit (11) au travers desquels les composants du signal stéréo sont alimentés, et un canal latéral (12) qui reçoit un signal de différence provenant des signaux principaux du canal gauche et du canal droit. Ledit signal de différence du canal latéral est déplacé en quadrature (par exemple + ou - 90') par rapport aux canaux principaux du processeur, réglé au moyen d'une commande de gain variable (17), filtré à basse fréquence (36) et rajouté (18, 20) aux canaux principaux de gauche et de droite avant les sorties stéréo. Le processeur permet d'améliorer encore davantage les signaux en combinant l'effet susmentionné avec une alimentation transversale anti-phase à gain réglé (30, 32) entre le canal principal gauche et le canal principal droite pour produire un élargissement de l'image qui compense les perturbations indésirables de l'image dues au canal latéral dont la quadrature est déplacée. On peut obtenir un effet avantageux grâce à la combinaison du signal de différence à quadrature déplacée et des signax transversaux anti-phasés que l'on commande par un potentiomètresynchronisé à utilisateur unique permettant de modifier conjointement, et l'un par rapport à l'autre, le gain de ces effets combinés, selon une loi de commande unique décrite dans l'invention.

Title: Method and apparatus for manufacturing articles of an expanded thermoplastic synthetic material
IPC: B29K105/04
Filed: 1990-01-03
Granted: 1993-09-15
Abstract: In the manufacturing of substantially dry articles of an expanded thermoplastic synthetic material, during heating-up of the mould wall parts by means of steam, an air pressure which is equal to or slightly higher than the pressure of the steam used for heating-up is maintained in a mould cavity filled with preexpanded synthetic-material particles and connected via passage-openings to the steam chamber. Once the mould wall has reached the temperature of the saturated steam, the air pressure is lowered for fusing of the expanded synthetic-material particles, and the synthetic-material particles are heated to the temperature necessary for fusing or sintering by the steam flowing in. An apparatus (10) suitable for carrying out the method is to have at least one connecting line (30) which leads from the mould cavity (17) to the outside of the foaming device and is provided with a connected valve-controlled operating line (37), in order in this way to introduce compressed air for building up the counterpressure in the mould cavity and for sucking out steam. At least one of these operating lines can accommodate the means (31) for filling the mould.

Abstract: The invention concerns a suction roll (10) for a paper machine, on which the paper web is pressed towards the outer face of the roll mantle. The suction roll (10) is divided, in the axial direction of the roll, into at least three vacuum spaces (A1,A2,A3). In the interior of the suction roll (10), there are at least two partition walls (17a,17b), by means of which the suction space (13) is divided into separate zones of negative pressure. The lateral vacuum spaces (A1,A3) in the suction space can be subjected to a higher negative pressure than the vacuum space (A2) in the middle area of the roll, whereby the profile of negative pressure is formed such that the negative pressure increases across the width of the roll towards the lateral areas. The invention also concerns a method for producing a desired pressure profile for a suction roll. <IMAGE>

Abstract: A totally enclosed electric motor which is effectively cooled by means of an internal ventilation system and an external ventilation system. The internal ventilation system includes an internal fan (30) driven by the rotor which forces internal ventilating air into and along an annular series of longitudinal internal ducts arranged adjacent to the internal cylindrical wall supporting the stator. The internal ventilating air leaving the internal ducts enters a brush compartment where the air is directed axially over the commutator and through the stator-rotor arrangement and back to the internal fan. The external ventilation system includes an external fan (34) driven by the rotor which forces external ventilating air from the atmosphere into and along an annular series of longitudinal external ducts (90) arranged radially outwardly from the series of internal ducts and into exhaust compartments at the far axial end of the motor.

Title: Means for supplying gaseous fuel by an apparatus using the combustion of such a gas stored in a liquid condition
IPC: F24C5/02
Filed: 1990-08-29
Granted: 1992-03-04
Abstract: An apparatus which is heated by a gasified liquid fuel has between the liquid fuel reservoir and a burner, a flow regulator/evaporator consisting of two porous masses separated by a recondensation chamber, the valve for cutting off the combustion being provided between the burner and the downstream mass. Liquid fuel can accumulate in the recondensation chamber so that, for startup of the system, there is an increased flow of fuel through the downstream porous mass to the burner to allow rapid heat up of the heat-distributing member. After the initial heating period the flow to the burner is determined by the porosity characteristics of both masses in series.
