Abstract: Abstract of the Disclosure A vertical filing system is provided wherein documents are filed in the spaces between a plurality of filing bars contained in a cabinet by hanging the documents on pins extending through the bars and outwardly into the spaces. In the closed, filing position, the pins extending from any one bar extend into the space between bars and overlap the pins extending into the space from an adjacent bar. In the open position, any two adjacent filing bars are separated such that the oppositely coacting pins on adjacent bars do not overlap and documents can be either inserted and filed or removed therefrom. In a preferred embodiment, openings are provided in each filing bar through which pins from adjacent bars can extend, the preferred pin-opening sequence on the filing bars being pin-opening-opening, pin-opening-opening, and so on.

Abstract: SPRING ASSEMBLY            Abstract of the Disclosure A spring assembly for mattresses, innersprings, and the like.  The assembly comprises rows of coils, each row com-prising a continuous length of wire formed into a plurality of coils interconnected by Z-shaped wire segments alternately dis-posed at the top and bottom of the coils.  Adjacent rows of coils are connected by a helical wire wound through overlapping Z-shaped wire segments.  The overlapping connected segments on opposite sides of each coil are located in a common diametrical plane of the coil so that complete compression of the coil does not result in the coil being pulled laterally, twisted and dis-torted.

Abstract: ABSTRACT    A reflection sensing apparatus detects the prior exposure history of individual frames of an annotatable archival microfiche film card (20).  A light source used to expose the microfiche to the record image is positioned to convert a reserved sensing area (296, qrst), which is outside the record image but within the frame, from an opaque and reflecting area to an irreversibly clear and transparent area upon exposure.  The reserved area (236, qrst) of the microfiche film card frame is interrogated by automatic photoreflection sensing immediately prior to exposure of a given frame to disclose its prior exposure history.  Suitable warning systems indicate the imminence of multiple exposure, and an automatic disabling feature pre-vents accidental re-exposure.  A manual override means controlled by the operator must be actuated to allow re-exposure of a previously exposed frame.          An alternative pre-exposure sensing of the re-served area by optical transmission methods is described.  The apparatus also serves to detect failure of the light source on initial exposure of a chosen frame by a second photoreflection sensing after exposure, or alternatively by transmission sensing during exposure.

Abstract: Abstract Collector-Output for Hollow Beam Electron Tubes In a microwave electron tube such as a gyrotron, a hollow beam of electrons passes thru the inter-action cavity into an output waveguide carrying the generated energy in a mode with circular electric fields.  According to the invention, the beam is caused to expand, passing thru a gap in the wave-guide to be collected on a larger, surrounding col-lector.  The collector energy is thus reduced.  The wave energy jumps the gap and continues down the waveguide.  Wave energy leaking into the collector may be absorbed by lossy material therein or be carried off by waveguides to external loads.

Abstract: ABSTRACT     A crystal diffraction instrument or diffraction grating instrument with an improved crystalline structure or grating spacing structure having a face for receiving a beam of photons or neutrons and diffraction planar spacing or grating spacing along that face with the spacing increasing pro-gressively along the face to provide a decreasing Bragg diffraction angle for a monochromatic radiation and thereby increasing the usable area and acceptance angle.  The in-creased planar spacing for the diffraction crystal is pro-vided by the use of a temperature differential across the crystalline structure, by assembling a plurality of crystal-line structures with different compositions, by an individual crystalline structure with a varying composition and thereby a changing planar spacing along its face, and by combinations of these techniques.  The increased diffraction grating element spacing is generated during the fabrication of the diffraction grating by controlling the cutting tool that is cutting the grooves or controlling the laser beam, electron beam or ion beam that is exposing the resist layer, etc. It is also possible to vary this variation in grating spacing by applying a thermal gradient to the diffraction grating in much the same manner as is done in the crystal diffraction case.

Abstract: RESISTIVITY LOGGING SYSTEM ABSTRACT OF THE DISCLOSURE       In the preferred and illustrated embodiment of a downhole oil well resistivity logging tool having a focused electrode, the current ideally flows from the electrode radially outwardly in a thin sheet deep into the earth's formation adjacent to the well.  There is an undesirable vertical current component along the electrodes which distorts the measurement of resistivity.  First and second alternate embodiments are set forth which utilize additional balanced electrodes in the electrode array. They establish a vertical current  in the adjacent formation.  The vertical current is varied by means of an oscillator connected to the balanced electrodes, and the voltage of the electrodes is monitored to detect zero crossing.  Zero crossing is indicative of reduced vertical current flowing in the formation.  At this instant, the entire current flow from the electrode array is radially into the formation whereby measurements of the current flow and voltage of the current emitting electrode enables calculation of the formation resistivity.
