Patent EP-0651859-A1 (EP)
Title: Rotary compressor with stepped cover contour.
Inventor: TANG PETER YAO
IPC: F04D29/44
Filed: 1993-07-15
Abstract: A compressor assembly includes a housing, and a rotatable impeller within the housing which includes a hub and blades extending from the hub. A ring circumscribes the leading edge of the blades, and cooperates with a groove in the housing to define a clearance therebetween which is larger than the clearance between the connecting edge of the blades and a corresponding conforming portion of the housing. This permits free flow of gas around the ring to enhance the operating range of the compressor wheel. The ring also stiffens the blades, permitting the thickness of the hub to be reduced, thereby further enhancing the operating range of the compressor wheel.

Abstract: L'invention concerne un procédé de division de la teneur en sulfure de liqueur verte en une partie riche en sulfure et une partie pauvre en sulfure par cristallisation de carbonate de sodium (Na2CO3). On procéde à la cristallisation du carbonate de sodium par évaporation de la liqueur verte avec un taux d'ions hydroxide [OH-] et d'ions sulfure [HS-] tel que la liqueur obtenue après évaporation de la phase solide présente un taux de sulfure élevé et une teneur faible acceptable d'ions carbonate [CO¿3?2-]. Avant l'évaporation, on augmente la teneur en ions hydroxide dans la liqueur par addition de chaux-vive (CaO). On dilue la phase solide (carbonate de sodium et carbonate de calcium) que l'on a séparé avec de l'eau de manière que les cristaux de carbonate de sodium forment une solution et en même temps on donne à la solution une teneur en cations favorisant la caustification entreprise ultérieurement. On procède à la caustification dans une installation de caustification classique. Après séparation de la boue de caustification (CaCO¿3?) formée pendant les processus de caustification, on obtient une liqueur blanche à faible taux de sulfure et faible teneur en carbonate que l'on utilise dans le processus de cuisson, et après oxydation, ainsi que dans la délignification à l'oxygène avant blanchiment final de la pâte.

Abstract: Efficient paving operation requires that the levelling operation of asphalt be carried out accurately along a reference line (A) which follows a given direction along a roadside. A simple and effective automatic control device for controlling the steering direction in conjunction with adjustments of the screed (6) for an asphalt finisher (1) (shortened to finisher) is presented. The control device automatically regulates the extension or contraction of the screeds (6) on both sides of the finisher (1) in reference to a visual display of the reference line (A) following some objects along the roadside. The visual detection system of control is simple and economical and provides an accurate control over the direction of paving.

Abstract: In order to develop a laser cutting device in a simple manner with regard to an improved work result, for example in respect of the edge quality achievable, the minimising of burr and the saving of rework, it is proposed to arrange a gas-mixing device (5) upstream of a conventional cutting head (1) which is provided with a nozzle chamber (3) for directing a gas. The output line (6) of the gas-mixing device (5) is connected to the cutting head (1). The gas-mixing device (5) is provided with an inlet line (7) carrying the main gas, for example N2, and further inlet lines (8, 9, 10) which serve to carry auxiliary gases which, either individually or in combination, can be added in a defined manner to the main gas flow flowing via the inlet line (7), so that a gas mixture of defined composition always flows via the outlet line (6) in the direction of the cutting head (1). To mix the auxiliary gases, each inlet line (8, 9, 10) has an injector nozzle (14, 14', 14'') allocated to it, the cross-section of flow of which is adjustable and which is connected on the outlet side to a line element which directs the main gas flow. <IMAGE>

Deflection from the main stream is brought about using the Coanda Effect. The hydraulically working channel, i.e., the main stream channel has an upstream corner in common with the branch stream channel which corner is rounded in the form of an arc of a circle between the upstream channel and the branch channel and which converges toward the corner and extends opposite that wall of the upstream channel leading toward the corner and forms with the corner an outflow gap, such that the momentum of the main stream flow which emerges, creates the Coanda Effect, thereby deflecting the controlled flow of water into the branch channel.

Abstract: A frame relay protocol-based earth station interface architecture provides full mesh connectivity for a relatively small number of network stations. The fundamental component of the architecture is a frame relay protocol-based switch (110), which employs a network interface "frame relay" standard to define the muliplexing of multiple virtual ports across single physical communications port. Through address and control fields of its connectivity control software, the frame relay protocol-based switch (110) can be dynamically configured to provide multilayer addressing and device selectivity, thereby enabling point-to-point connectivity of multiple terminal devices, such as a plurality of audio circuits (170-1...170-N), to be effected via a single port. Dial codes on the station side of an audio signal muliplexer link (135) are translated into frame relay addresses (data link connection identifiers) that are added to each frame of data for routing though the network. <IMAGE>
