Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to novel interconnecting means for selectively connecting a pushbutton slide on a tuner with either an AM tuning slide or an FM tuning slide.  Each of the tuning slides carries a resilient interconnecting member, the other end of which is received in a slot in a shift plate.          The interconnecting members each have a lateral pin which may be received in a notch in the pushbutton slide.  When the shift plate is moved laterally one of the lateral pins on one of the resilient interconnecting members is engaged in the notch on the pushbutton slide to connect that tuning slide with the push-button slide.  This improved apparatus is simple in structure and thereby may be easily manufactured and assembled and provides satisfactory operation over a long period of time.

Abstract: ABSTRACT         A treatment is disclosed for organic biodegradable, polymeric materials, such as organic synthetic resins and cellulosic materials, with monochloroacetate esters of chlorinated phenols.  This treatment not only renders such materials less susceptible to degradation by microorganisms but does so without appreciable deterioration of other desirable properties of the materials such as occurs from treatment by chlorinated phenols.  The ability of the monochloroacetate ester to effect such improved results is surprisingly unique and not shared by even closely related compounds, such as the dichloroacetate and trichloroacetate of chlorinated phenols.

Abstract: THERMOPLASTIC DUPLICATION PLATE MANUFACTURING APPARATUS  Abstract of the Disclosure An apparatus for manufacturing thermoplastic duplica-tion plates having a relief image thereon from thermoplastic resin sheets.  To this end, the apparatus includes a cylinder heated to a predetermined temperature onto the surface of which a sheet is fed and by which the resin sheet is, while clinging thereto, transported towards a transcription clearance.  A movable platen supported for movement between a standby position and an operated position cooperates with the hollow cylinder to define the transcription clearance and supports a matrix having a relief pattern thereon.  During the transportation of the thermoplastic resin sheet towards the transcription clearance, it becomes substantially semi-fluidized so that, as the sheet engages the matrix in the transcription clearance, the thermo-plastic resin penetrates deep into the indentations in the matrix forming the relief pattern, thereby producing a thermo-plastic duplication plate, when the resin sheet cools.  This apparatus has the advantage that the matrix is not curved so that the relief image transferred to the thermoplastic sheet is not distorted.

Abstract: A B S T R A C T     For drivingly connecting the external cylindrical surface of an inner machine element to the internal cylindrical surface of an outer machine element, such as a shaft to a pulley, forward and rearward clamping rings are spaced axially apart from one another and have cir-cumferentially spaced aligned bolt holes disposed parallel to the axis of their internal and external cylindrical surfaces. One ring has smooth bolt holes and the other ring has threaded bolt holes, these holes re-ceiving threaded clamping bolts. Mounted in the space between the two clamping rings are pairs of alternately oppositely facing resilient coup-ling rings of substantially Z-shaped cross-section having bolt holes aligned with the clamping ring bolt holes. Each coupling ring consists of radially-spaced inner and outer annular rims connected at acute angles to the opposite ends of an annular web inclined at an oblique angle to the axis of the cylindrical outer and inner surfaces of these coupling rings. tightening the clamping bolts urges the clamping rings toward one another, thereby compressing the coupling rings so that their obliquely inclined webs are deformed into more nearly radial positions to the axis of the clamping rings, consequently forcing the inner and outer annular rims to simultaneously expand and contract in opposite directions into frictional coupling engagement with the external and internal sur-faces respectively of the inner and outer machine elements.

Abstract: ACCESS TO FLOPPY DISK STACK               ABSTRACT OF THE DISCLOSURE    A method and associated apparatus for positioning an auto-sustaining split precisely and quickly in a rotating stack of floppy type storage disks. Such split permits access to otherwise inaccessible storage surfaces facing the split and constrains these surfaces to circumferentially uniform rotational paths suitable for highest density storage.          The ventilation pressure between the disks is set initially to a level above the threshold for formation of the auto-sustaining split.  An externally transported air nozzle, positioned initially to estimated (coarse) coincidence with an axial component of a target cylindrical address, emits a pulsed jet of air into an aligned interface.  This forms a partial split having a circumferentially irregular shape inappropriate for storage transducing access.  The partial split forms more quickly than the auto-sustainable split and provides a wide relatively unvarying positional reference, by comparison to an unsplit interface.  The partial split is thereby useful for precisely determining the displacement between said split and the target interface position.  If a null displacement is detected the partial split is transformed into the auto-sustaining configuration by reduction of the ventilation pressure.  Otherwise, the partial split is repositioned in small corrective increments, in the appropriate direction for nullifying the displacement, and the displacement is redetermined.  The time required to form a partial split is much less than the time required to form an auto-sustaining split, and the average increment of access delay due to the corrective repositioning of the partial split is also relatively small.   Progressively differentiable indicia on Successive disk edges facilitate determination of the split displacement.

Abstract: "CAPACITANCE SYSTEM FOR HEAVY PHASE DISCHARGE OF SECOND STAGE CENTRIFUGAL SEPARATION CIRCUIT"                 ABSTRACT OF THE DISCLOSURE       A single capacitance vessel is provided to receive the excess heavy phase discharges (normally water) from a bank of disc-nozzle centrifugal separators. The vessel has a reservoir chamber with a weir at one end.  The heavy phase streams are delivered into the reservoir of fluid retained in this chamber.  In the event there are any hydro-carbons in the heavy phase fluid, the former rise to the surface of the reservoir fluid and pass over the weir, together with some water.  An inert gas blanket within the vessel pressurizes the reservoir so that a fluid backpressure is maintained at the discharge outlets of the separators.  By use of this system, any fluid returned from the reservoir to the separators (which occurs when the feed to the separators is low in water) is substantially free of hydrocarbons which, if present, would deleteriously affect the operation of the separators.  In addition, the fluid passing over the weir is separated by a downstream weir system into hydrocarbon-rich and water-rich fractions which are separately recovered.

Abstract: Abstract of the Disclosure Method for isotope separation or enrichment in a vaporous mixture of compounds containing the isotopes to selectively excite the group of mole-cules containing one isotope by means of coherent, polarized electromagnetic radiation (lasers) in which a frequency shift is prevented or greatly reduced and the excitation state can be driven very high to beyond the dissociation limit.  This is accomplished by adjusting the frequency and field strength of the radiation so that the dipole moment of the group of molecules to be ex-cited, oscillates, at least at the final amplitude, mainly in phase opposition to the exciting field, and the other group of molecules mainly in phase with the exciting field.  In another procedure the radiation has a frequency closer to the resonance frequency of the group of molecules to be separated and is of the order of magnitude of the isotope-determined frequency difference, and both groups of molecules operate in phase opposition.
