Abstract: The precision smoothing tool for the superfinishing of bores, shafts or the like with any cross-section and made of very hard metallic material has grooves (18) between concentrically stepped working areas (17), the transition areas from the grooves to the working areas running approximately tangentially. The precision smoothing tool does not work by cutting but by material compaction on the workpiece to be treated. The basic body is made of a high-alloy pressure-sintered material, a thin nickel coating is applied to this in the working area for the purpose of adhesion, and a hard coating of titanium, in particular TiN or TiC2N, is applied to the nickel coating. In this way, maximum dimensional accuracy and smoothness of the treated part is obtained. …<IMAGE>…

Abstract: A wireless communications network includes a local area network connected to a plurality of nodes (12) which perform bidirectional wireless communication with mobile stations (10) as controlled by a controller (3). Each node has a geographic area, termed a cell, within which mobile stations can communicate with the node associated with the cell. A cell interference graph is read into the controller, and a maximal independent set of nodes is determined. Each node in the maximal independent set of nodes is pint in a set termed ACTIVE for performing wireless communication with mobile stations in their respective cells. Nodes which are not in the maximal independent set of nodes is put in a set termed WAITING to wait for permission to enter the set ACTIVE. A node in the set ACTIVE which has completed communications sends a completion signal to the controller. The controller then examines which of the nodes in the set WAITING is not adjacent to another node in the set ACTIVE, and such nodes are entered in a set termed CANDIDATES. Nodes in the set CANDIDATES are moved to the set ACTIVE according to a predetermined criteria.

Abstract: An optical system for reading and reproducing recorded information from an optical waveguide recording medium (1) is characterised in that an optical frequency modulating element (33) for modulating light emitted from a super luminescent diode (SLD) as a light source (35) is provided between the SLD and a beam splitter (36). The optical frequency modulating element (33) may comprise an ultrasonic light modulating element (33a) with a frequency-modulated drive voltage to diffract the light from the SLD (35) and a slit (33b) which limits the spatial spectrum of the diffracted light. As the voltage to drive the ultrasonic light modulating element is frequency-modulated, the pitch of an elastic wave formed in the ultrasonic light modulating element will be modulated. This varies the diffraction angle of the light of the same frequency, thus changing the frequency of light that passes through the slit. Alternatively, the optical frequency modulating element (33) may comprise an acoustooptic modulating element (33c) driven at a high frequency, and a movable slit (33d) to select the desired diffracted light.

Abstract: A nozzle and valve assembly (100) comprises a cylinder (102) having an open end and a piston (104) having a conical deflecting surface (140) on its lower end. A first supply pipe (114) is connected to the interior of cylinder (102) through an aperture (110) in its wall. A second supply pipe (120) is connected through a bore (119) formed in the wall of the cylinder (102) to an inwardly directed orifice (130) positioned at the bottom of the cylinder (102). In use, with the piston (104) in a raised position, a solid product is supplied through the first supply pipe (114) and discharged through the open end of the cylinder (102) into a container. The piston (104) is lowered, thereby closing off the aperture (110) in its wall and hence the first supply pipe (114), until its lower end is level with the inwardly directed orifice (130). Liquid is then supplied through the second supply pipe (120). The liquid washes away any solid on the conical deflecting surface (140) and is formed by the conical deflecting surface into a smooth slow flowing column of liquid.

Abstract: Known quartz crystal resonators, such as flexural mode or length extensional mode, suffer from many drawbacks including high series resistance and the inability to be miniturised. 
     The present invention provides a torsional quartz crystal resonator overcoming the above disadvantages and moreover operating in the frequency range 200-600 kHz with a zero temperature coefficient and can be manufactured cheaply and easily using an etching process. 
     This is achieved by the plate quartz crystal which is normal to the z or optical axis being rotated about the electrical axis by a cut angle ø where -90° < ø < 90° and then further rotated around the rotated z′ axis by a further cut angle ϑ where - (10° to 80°) < ϑ < + (10° to 80°).

Abstract: A time-dependent record depicting the motion of one or more selected atoms with a time resolution equal to or shorter than 10⁻¹² second is generated by applying an electric field to a field emission tip (10). Electrons emitted from the selected atoms are focused into a beam which is swept over a spatially resolved electron detector (14) for sensing the intensity of the beam as a function of the for creating the record. One- or two-dimensional records can be generated without signal averaging. The electrons can be directed onto a spot on a surface where dynamics are to be probed, and the electrons scattered or emitted from said surface are then focused into the electron beam. This method can also be used for transmitting information to a remote location at high frequency.

Abstract: Procédé et appareil destiné à réduire les émissions de NOx des brûleurs à mélange préalable en remettant en circulation les gaz de fumée. Les gaz de fumée sont extraits du haut-fourneau, en empruntant un ou plusieurs conduits, par l'effet aspirant du gaz combustible et de l'air de combustion passant à travers une partie venturi d'un tube de brûleur. Les gaz de fumée se mélangent à l'air de combustion dans une chambre d'air primaire avant la combustion de manière à diluer la concentration de O2 dans l'air de combustion, ce qui abaisse la température de la flamme et, partant, réduit les émissions de NOx. Le système de remise en circulation des gaz de fumée peut être adapté sur des brûleurs à mélange préalable existants ou incorporé aux nouveaux brûleurs à faible production de NOx.

Abstract: Even when a bucket is changed to an optional special bucket, a path control as intended by an operator can be automatically performed without making correction for the nose angle of the original bucket. For this purpose, in an operation mode determining section (9), there is calculated the possibility (U2) of an operation mode being a nose fixing mode depending on how much a bucket attitude angle (γ) is deviated from a predetermined angle, and there is also calculated the possibility (U1) of an operation mode being a mode for fixing an angle to the ground depending on a magnitude of a value for computing an allowable angle held with respect to the ground, whereby an operation mode during the automatic path control can be automatically determined through the comparation between these two possibilities (U1, U2).
