Title: Tumble grinder with screen portion
Inventor: HOGAN PATRICK J
IPC: B02C21/02
Filed: 1993-02-02
Granted: 1997-10-14
Abstract: A tumble grinder is disclosed in which material which is already sufficiently small in size, primarily being abrasive aggregate or earthen material, may be discharged from the receptacle to bypass the comminution apparatus and thus substantially reduce wear thereto.  A portion of the cylindrical wall of the receptacle is provided with classifying openings, for example by providing a screened opening as a band around the receptacle.  The classifying openings permit material which is already smaller than the size of the openings to fall therethrough, thereby bypassing the comminution apparatus.  Preferably, a conveyor is positioned beneath the receptacle, to catch and discharge the material which falls through the screen or other classifying openings to a pile located away from the receptacle.          Sidewalls positioned on either side of the receptacle stop any material which is flung out to the side, and redirect it down onto the conveyer.  The apparatus may be advantageously mounted on a trailer, for towing from site to site.  In such an arrangement, it is advantageous to provide an integrated, transportable system, in which the receptacle is moveable between an operating position and a transportation position.

Abstract: A fluid pump with a rotary impeller is disclosed which comprises an electromagnetically-driven, bearing-free, seal-free rotary impeller (16) levitated by localized opposed, magnetic forces and by fluid forces, or by localized opposed magnetic forces only. Levitation by localized opposed magnetic forces alone or by a combination of magnetic and fluid forces of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping mechanisms, which can be of importance in pumping of physiological fluids such as blood. The levitating forces of the present invention are applied both axially and radially with respect to the impeller. The magnetic forces are provided by a combination of diamagnets or solenoids (70, 70', 75, 75'), opposed by permanent magnets, solenoids or electromagnets (70, 70', 75, 75'). The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.

Abstract: The present invention provides a transparent functional film comprising a transparent plastic substrate film and a hard coat layer provided thereon, wherein functional ultrafine particles are present in a highly localized form, thereby enabling the functional ultrafine particles to effectively exhibit their function and, at the same time, the hard coat layer to have a good adhesion to the functional ultrafine particle layer; and also an antireflection film and processes for producing the transparent functional film and the antireflection film. A functional ultrafine particle layer 2 is formed on a release film 1. Separately, a resin composition for a hard coat layer is coated on a transparent plastic substrate film 3. The coated release film is laminated by press bonding to the coated transparent plastic substrate film so that the functional ultrafine particle layer 2 faces the resin composition coating, thereby causing part of the functional ultrafine particles 5 to be embedded in the resin composition coating for a hard coat layer. The resultant laminate is cured, and the release film 1 is then peeled off. In the resultant transparent functional film, the functional ultrafine particle layer 2 is partly embedded in and fixed to the hard coat layer 4, and the functional ultrafine particles 5 are localized in the hard coat layer 4 on its surface side.

Abstract: Each information recording track has pre-formatted fore and rear header  sections containing  address  information identifying the track, which permit each of the recording tracks to be accessed from either of the header sections.          A predetermined synchronization signal is pre-formatted in a storing area for each frame having a predetermined data size, so that information can be non-rewritably recorded onto the storing area for a predetermined frame by referring to the  pre-formatted  synchronization  signal.    With  this arrangement, data can be recorded onto a selected information recording track in either of the directions of relative reciprocating  movement  of  the  recording  medium  to  a recording/reproducing head, and thus the recording speed can be increased.   The  arrangement  also allows data to be recorded even when one of the header sections has become unreadable due to some defect of the recording medium, and prevents occurrence of jitters in reproduced signals by allowing data to be recorded accurately at predetermined locations for each of the frames.
