Abstract: 48, 439 ABSTRACT OF THE DISCLOSURE          A support  structure  for unitizing coil  turns into a single member and bracing each coil of a multi-coil stator dynamoelectric machine.  Each stator coil includes several  turns  relatively  concentrically disposed.   Each coil turn constitutes two longitudinal conductor portions and two end turn conductor portions.  One end turn portion serially connects two longitudinal portions and the re-maining  end  turn portion  serially  connects one of the longitudinal  portions with  a longitudinal portion of a concentrically adjacent coil.  Each coil preferably lies in a plane defined by a portion of a cylinder and the coils are disposed in a cylindrical arrangement having a longitudinal axis therethrough such that one longitudinal portion of the outermost coil turn lies along the outer radial  extent  of  the  cylindrical  arrangement  and  the remaining longitudinal portion of the outermost coil turn lies radially nearer the longitudinal axis of the cylin-drical arrangement.  A rigid foundation member is situated in the plane of each coil within the concentrically inner-most turn.  Turns of each coil are structurally connected either directly to the foundation member or indirectly to the foundation member by being intermediately joined to a turn already joined to the foundation member.  The concen-tric turns of each coil are separated by a predetermined distance  through  the use  of  interposed  spacer members situated at desired axial and circumferential locations. Such coils present a spiral pancake appearance and are cooperatively  disposed  in  the  cylindrical  arrangement 13           48,439 between radially inner and outer supporting structures. Appropriately shaped wedges are disposed between selected coils and internal/external supporting members to account for the skewed or spiral manner in which each of the coils is arranged in the substantially cylindrical arrangement. Radial tie rods extending between the radially internal and external support members structurally integrate those members so as to insure structural integrity of the cylin-drical arrangement.  The radially external support member is preferably configured to extract load components from individual coil turns exposed at the cylindrical arrange-ment's outer periphery by either having radially inwardly directed struts extending between adjacent turns or having notches within which the radially outer conductor turns, when canted, are receivable.

Abstract: LOGIC FOR COIN OPERATED OFFICE COPY MACHINE VENDER     Abstract of the Disclosure In a wet cycle copier of the small tabletop mounted variety, conversion is made for vending in the absence of frequent key operator attention.  Incidence of power interruption provides for a soak cycle to occur wherein the liquid toner is cycled through the machine without drum rotation.  Rotation of a glass selenium coated drum against a dried and abrading liquid applicator is avoided.  After the soak cycle and assuming uninterrupted power, a cleaning cycle is initiated once every 24 hours.  Assuming a lack of machine use, this cleaning cycle lubricates both toner application roller and drum to assure a wet toner applicator.  Dispersant replenishment is supplied from a large volume reservoir under logic control with provision made for automated machine shutdown where dispersant on demand is not supplied.          Provided modes of operation include coin vending, countermechanism vending and direct owner access vending with a tamper proof interface between the provided modes.  Multiple copies are provided in the countermechanism and direct owner access modes with positive memory cancel upon where these modes are charged.  Coin operation includes a system of logic controlled directives and selected flashed warning with a resultant information interface to enable virtually any unskilled operator to run the machine.  This same coin vending also includes priority of events logic to prevent both the retention of a coin without the machine ready to copy and to require vending once a coin is retained.  In the absence of coin, vending is prevented to destroy the relatively low profit margin of the machine.  Vending of two discrete sizes of paper is provided with supervision and control logic interlocks to detect both jamming of the paper and exhaustion of paper supply with automatic indication and machine switching function to the remaining available paper supply.

Abstract: DEPOSITED FILMS WITH IMPROVED MICROSTRUCTURES AND METHODS FOR MAKING               ABSTRACT OF THE DISCLOSURE       Methods  for  improving  microstructures  of line-of-sight  deposited  films  are  described.   Co-lumnar  growth  defects  (228,  230)  ordinarily  pro-duced by geometrical shadowing during deposition of such  films  are  eliminated  without  resorting  to post-deposition  thermal  or  mechanical  treatments. The native, as-deposited coating qualities, includ-ing homogeneity,  fine  grain  size,  and  high  coat-ing-to-substrate  adherence,  can thus  be  retained. The preferred method includes the steps of emitting material from a  source  (124a)  toward  a substrate (200)  to deposit a coating  (201)  non-uniformly on the substrate surface,  removing a portion  (212) of the  coating  uniformly  over  the  surface,  again depositing  material  (215)  onto  the  surface,  but from a different direction, and repeating the fore-going steps.   The quality of  line-of-sight depos-ited  films  such  as  those  produced  by  sputtering, progressively  deteriorates  as  the  angle  of  inci-dence  between  the  flux  and  the  surface  becomes increasingly  acute.   Depositing  non-uniformly,  so that the coating  (201)  becomes progressively thin-ner as quality deteriorates,  followed by uniformly removing some of the coating, such as by resputter-ing,  eliminates  the  poor  quality  portions  (201b, 201c), leaving  only  high  quality  portions  (201a, 201d) of the coating.  Subsequently sputtering from a different direction applies a high quality coat-ing to other  regions of  the surface.   Such steps can be performed  either  simultaneously or  sequen-tially to apply coatings  (350, 360) of a uniformly high  quality,  closed  microstructure  to  three-di-mensional or large planar surfaces.

Abstract: VAPOR MASS FLOW CONTROL SYSTEM             Abstract A chemical vapor delivery system comprises a bubbler partially filled with liquid to be vaporized by passing a  carrier  gas stream through  the  liquid.   To  reduce error in supplying a continuous, uniform mass flow of vaporized liquid to a using system, the pressure in the bubbler is sensed and compared with a reference pressure to provide a signal representing a pressure differential which is used in a computation by a flow controller to control the flow of carrier gas.  A similar temperature differential is  assessed by the flow controller which also monitors the level of liquid  in the bubbler to further  refine the accuracy of  supplying  the uniform mass flow of vaporized liquid.

There is thus obtained a reaction product containing (A) a methanol phase having dissolved therein the nickel ylide catalyst and (B) an alpha olefin phase.  These two phases are then separated from each other to recover the alpha olefin phase.   The use of methanol as the solvent medium causes the reaction product to resolve itself into two phases,  an upper phase containing most of the oligomer product and a lower methanol phase carrying the catalyst dissolved therein.   This permits easy separation of the product from the reaction mixture and also permits effec-tive recycle of methanol with dissolved catalyst.   The product obtained contains normal alpha olefins having from about four to about 100 carbon atoms, generally from about four to about 50 carbon atoms.
