Abstract: USE OF SILICONE OIL AS A POLYETHYLENE OXIDATION RETARDANT IN A TONER IMAGE FUSING APPARATUS     ABSTRACT OF THE DISCLOSURE     A contact fuser assembly for use in an electrostatic re-producing apparatus including an internally heated fuser roll struc-ture comprising a rigid or non-deformable, thermally conductive core capable of interacting with a material applied thereto in such a manner as to form a thermally-stable interfacial coating intermediate the surface of the core and a release coating also formed thereon.  The interfacial coating strongly adheres to the core surface and prevents toner material from contacting the outer surface of the core.  The combined coatings have a sub-micron thickness and therefore present a minimal thermal barrier to the energy being conducted outwardly by the core.  The fuser assembly is characterized by the provision of means for controlling the in-teraction between the core and the material.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for analyzing an illuminated subject.  In the preferred embodiment, the subject is a stained blood smear.  A first signal is produced which represents a first predetermined wavelength band of the subject modified illumination at a region in the subject.  A second signal is produced which represents a second predetermined wavelength band of the subject modified illumination at the region.  The two wavelength bands are selected to produce differential contrast between at least two different regions in the subject.  The two signals are algebraically combined with thresholding to classify the subject regions in at least one of a predetermined number of categories.          Further, signal processing is employed to compile partial and complete features for a predetermined region or cell.

Abstract: ACTUATOR MECHANISM FOR DISK STORAGE APPARATUS     ABSTRACT     The invention relates to an actuator mechanism suitable for positioning a recording head over the surface of a recording disk.  The actuator consists of a planar coil etched from a copper laminated board.  The board is pivoted at one end and carries a recording head supported on an extended arm.  Magnets produce a flux perpendicular to the plane of the laminate so that current through the coil produces limited motion of the board about its pivot.  The actuator mechanism is located in relation to the disk so that the limited motion of the board moves the head over the disk from one transducing position to another.  The mechanism is included in a closed loop servo system which derives position information from servo tracks on the disk and enables track access and track following operations to be conducted.

Abstract: IMPROVED EXHAUST SYSTEM FOR    INDUSTRIAL PROCESSES     Abstract of the Disclosure A textile or other industrial machine, of the type where one or a plurality of operations generate a gaseous dis-charge at a work station, is provided with at least one wall leaving at least one open side and includes an exhaust hood on the top which communicates with the air space above the work station.  A first fan communicates with the exhaust hood to withdraw smoke, fumes, vapors and steam from the air space and deliver it to the outside.  A second fan draws in fresh, un-conditioned outside air and delivers it to a delivery nozzle extending along the front edge of a work table in said work station.  An air curtain is thus formed between the delivery nozzle and the aforementioned exhaust hood, whereby the smoke, fumes, vapors and steam are confined within the air space above the work table until withdrawn through the exhaust hood.  Further the delivery nozzle provides a source of fresh air to replace the air withdrawn so that the conditioned air in the workroom surrounding the textile machine is substantially unaffected.  In a preferred embodiment, a portion of the exhausted air is recirculated through the air space above the work table prior to being treated by some type of cleaning apparatus, so that the volume of air per unit time passing through the cleaning operation is reduced.  Further the amount of outside air drawn into the system is kept to a minimum to prevent air turbulence in the air curtain and rapid temperature changes in and around the work table, which might lead to a fogging problem.
