Title: Tape reel
Inventor: ELLIOTT JAMES P
IPC: G11B23/037
Filed: 1987-06-19
Granted: 1992-05-26
Abstract: ABSTRACT    A tape cassette is described having top and bottom cassette halves, tape reels and low frcition washers between the tape reels and the cassette halves.  Each tape reel is made of a plastic hub connected to two plastic flanges, each flange having intentionally curved circumferential edges.          Each flange also has a raised, annular centering ring abutting and rotating only on the washers for rotatably supporting the tape reels relative to the tape cassette.  These centering rings minimize friction, prevent skewing of the tape reels relative to each other and, along with the curved edges of the flanges, permit the tape to be wound without damage.

Title: Method and means for reading electronic signal patterns stored on a movable image recording surface
Inventor: KUEHNLE MANFRED R
IPC: H01J31/28
Filed: 1988-05-10
Granted: 1993-05-04
Abstract: ABSTRACT OF THE DISCLOSURE      A scanning system for optoelectronically recorded signal patterns stored in a plural layer medium consisting of inorganic materials throughout and featuring a dielectric storage layer at the surface which faces an electron beam source.  The source beam first searches for a position mark associated with an image frame on the medium in order to establish a precise home position of the beam and associated coordinate axes prior to commencing the scan operation on that medium frame.  Then the beam scans a raster on the medium spending a certain dwell time at each resolution element of the raster.  Each time a frame is reached, the system is capable of altering the beam current in response to a pre-recorded exposure code in order to achieve the optimal retrieval of all information stored image-wise within said frame.  The system then collects electrons emitted from the medium due to the scanning beam in a collector, which incorporates a highly sensitive amplifier, for further processing, with the medium being movable frame by frame as desired.  In another system version, the electronic image on the medium as read using a sensing needle array that scans close to the medium surface making it possible to extract tunnelling electrons through the natural electron surface cloud as a result of an external electrical field applied between the needle and the medium.          The "tunnelling current" is modulated by internal, image-wise electrical field domains and the amplitude of the current is representative of the electronic image stored in the medium.

Abstract: DOUBLE-SIDED SANDING BLOCK       ABSTRACT OF THE DISCLOSURE         Conventional sanding blocks have the abrasive surfaced paper extending  from side to side and being secured  to  the  sides  which inhibits heavy lengthwise sanding  and the  surface of  the block upon which the abrasive paper is  secured is generally planar.   Some blocks permit the abrasive material to extend from one end to the  other but anchoring same against movement during  the  heavy  sanding  action  is  difficult.    The present block has a double-sided configuration enabling two different types of abrasive paper or the like to be secured one on each side thereof.  Blind slots are formed in each end of the block into which the ends of the upper and lower abrasive paper or material engage and which is held in place and tensioned upon the block surface by a resilient clip engaging within each  slot  frictionally holding  the  abrasive material  in position.    The  end portions of the upper and lower surfaces of the block incline  outwardly  and  towards  one  another  with  the central portion of the surfaces being spaced and parallel to one another.  A resilient pad may be secured to one or both  surfaces  of  the  block  to  cushion  the  abrasive material detachably spanning same.

Abstract: Abstract of the Disclosure A cleaning and treating apparatus which employs a series of nozzles or guns for propelling abrasives onto interior and exterior exposed surfaces of components.  The forces required to propel the abrasive materials are provided by fluid pressure supply sources which can be adjusted separately to deliver a wide range of high and low pressures to each individual nozzle outlet.  Having available these variably selectable fluid pressure sources at each individual nozzle, combined with means for directing each nozzle relative to the machined component being cleaned or treated, enables this apparatus to perform its intended function without distorting the surfaces upon which the work is being performed.  Furthermore, it allows an operator of the unique apparatus to correct any existing surface disconfigurations or otherwise control the shape of the component as desired.

Abstract: A plasma air purification device for producing a breathable effluent from contaminated air is disclosed which overcomes the limitations of known air purification devices.  The present invention comprises an alternating current plasma device with a porous spherical or granular material packed into the plasma zone.  The device of this invention provides air purification by decomposiing and deactivating toxic contaminants.          The contaminants that can be successfully processed include toxic vapors, gases and aerosols.  In addition, the air by-products such as NOx, O3 and CO are controlled to below toxic levels.  The presence of the porous packing enhances the performance of the device by further reducing air by-products formation, maximizing processing efficiency reducing power consumption, and increasing volume flow rate (i.e. reducing carrier gas residence time).

Abstract: ABSTRACT           A method and apparatus for the continuous casting of steel, for example, is described.  The method involves forming a continuously cast strand in a continuous casting mold which defines a casting passage having an inlet end and an outlet end.          The forming step includes admitting molten material, e.g., molten steel, into the inlet end and at least partially solidifying the molten material in the mold. The strand is withdrawn from the casting passage via the outlet end in a first direction and the mold is oscillated by alternately moving the latter in the first direction and in a second direction counter to the first direction.          Oscillation of the mold is regulated in such a manner that the oscillation frequency increases as the strand accelerates in a first range of speeds to a predetermined speed equal to or less than about 1.2 meter per minute and, perferably, in a first range of speeds extending from standstill to a predetermined speed be-tween about 0.8 and about 1.2 meter per minute. Oscillation of the mold is further regulated such that the oscillation frequency remains substantially constant while the oscillation stroke in-creases with strand speed as the strand accelerates from the predetermined speed in a second range of speeds.  The method described improves the surface quality of the strand.
