Abstract: A method and a equipment for processing of particularly finely divided material. The material is fed by means of a mechanical feeder device (2) and a pressurized equalization tank (4) into a fluidization chamber (5). A fluidized gas-solids suspension received is accelerated through acceleration nozzles (20) into a grinding chamber of a counter-jet grinder (19) so as to grind the solid particles. The ground gas-solids suspension is passed through connecting pipe (7) into a centrifugal classifier (8). A fine fraction is removed as a gas suspension through an opening (9). Additional air of low pressure is passed into the connecting pipe (7) and the coarse fraction is removed from the centrifugal classifier through a removal opening (10) in the peripheral face of the classifier into a pocket (12) outside said peripheral face, whereby the coarse fraction in the pocket (12) is removed batchwise by means of a closing device (13).

Abstract: The use of an alkoxylated stabiliser containing polyoxyalkylene chains to impart a core-sheath structure to particles of film-forming polymer to enable them to form a stable aqueous coating composition wherein the core contains film-forming polymer and the sheath contains the polyoxyalkylene chains which contain 6 to 40 oxyalkylene units some of which are covalently bonded to the core and which are provided by an alkoxylated C18 fatty alcohol containing more than one non-terminal and non-pendant ethylenic double bond. The stable aqueous coating composition can be formed even when the particles are very small (ie average diameter below 100 nm) without having to employ aromatic moieties or multiple terminal or pendant double bonds which either produce aromatic biodegradation products or are difficult to bio-degrade.

Title: Micromachined valve with polyimide film diaphragm
Inventor: SITTLER FRED C
IPC: F15C5/00
Filed: 1989-12-08
Granted: 2000-05-02
Abstract: A micromachined miniature valve used for gas chromatography has very low valve and interconnection dimensions to reduce the fluid volume inherent in other gas switching valves to thereby provide accurate measurements involving small gas flows. In order to reduce actuating diaphragm size, without encountering excessive stress concentrations in the diaphragm, the diaphragm can be polyimide film actuated in connection with a silicon valve body having valve seats with ports that are opened or closed by deflection of the diaphragm. Silicon wafers can be micromachined using batch fabrication techniques to provide the necessary valve seats and passageways for operating. The valve assembly is produced as a layered sandwich made up of individual wafers, including an actuator layer, a stop layer, a valve seat layer, and a layer which has flow channels receiving gas from the valve seat layer and making the necessary interconnections to provided outlets.      The diaphragm film is positioned between the valve seat layer and the stop layer, and is deflected or displaced to control passage of gases through the valve openings. The diaphragm layer is sealed to the silicon valve body by a process which involves fusing, such as glass frit or solder sealing.

Title: Optical head device
Inventor: MIYAKE TAKAHIRO
IPC: G11B7/1398
Filed: 1991-05-28
Granted: 1996-03-19
Abstract: An  optical  head  device  having  an  optical  system provided with at least a light source, a shaping prism, an diffracting element and a photodetector.  The light source emits light whose intensity distribution has an elliptic shape in its cross section orthogonal to the optical axis.          The shaping prism directs the light to a recording medium after shaping the intensity distribution thereof into a circular shape.  The diffracting element has diffracting regions formed by at least one division line substantially parallel to a reference direction.  The light reflected from the recording medium forms an elliptic bright portion on the diffracting element.  The photodetector is divided by a plurality of division lines, at least one of which is parallel to the reference direction.  When there is no focus  error,  the  diffracting  element  diffracts  the reflected light so as to converge it on the division line substantially parallel to the reference direction in the photodetector.   For example,  when the shaping prism is adapted to shape the elliptic intensity distribution with respect to its minor axis direction, the optical system is arranged so that the major axis of the bright portion is parallel to the division line of the diffracting element.          Thus,  it  is  possible  to  suppress  offsets  in  focusing control due to wave-length variations of light.

Title: Apparatus for comminuting solid waste
Inventor: FLAMENT GREGORY J
IPC: B02C18/18
Filed: 1991-09-10
Granted: 2003-02-25
Abstract: Apparatus for crushing, grinding and shredding solid waste material in which two interacting stacks of cutting and shredding elements are positioned on two substantially parallel shafts and mounted transversely with respect to the directions of waste material fed into the apparatus. Cutting members on one stack interact with cutting members on the other stack. In each stack adjacent cutting members are spaced from each other by a spacer. The spacers in the apparatus differ from those used in prior comminutors of this type in that they also have cutter elements on their periphery and thereby serve as cutters or shredders as well as spacers. This double function of the spacers increases the efficiency of the comminuting apparatus.      Most importantly there are cutting edges from the bottom to the top of each stack so that there are no intermediate elements on which strings or wires can be wrapped without encountering a cutting edge. While this is important in the shredding of relatively soft or easily shredded material, this is even more important in the comminuting of tires which have been reinforced with nylon cord or steel wire which have a tendency to wind around sections not having cutting edges. The process of effecting the difficult task of comminuting automobile and truck tires is also described.
