Abstract: Abstract of the Disclosure A maximum liquid level control valve for limiting the flow of liquid petroleum gas into a tank having a valve body, a float pivotally attached to the valve body, a closure flap, a spring acting between the valve body and the closure flap, and a cam device movable by the float.  The control valve which is mounted to a flange welded to the side wall of the tank has a valve seat and a passage for liquid to flow through the valve body into the tank.  The closure flap is movable toward the valve seat to a closed position and away from the valve seat to an open position.  The closure flap is movable to the closed position under incoming liquid pressure.  When the liquid level in the tank is below the maximum liquid level, the cam device acts on a stem which is attached to the closure flap.  with the cam acting on the stem, the closure flap cannot be moved to the closed position in response to incoming liquid pressure. When the maximum liquid level is reached, the cam device rotates unblocking the stem, the spring constant of the spring is overcome by incoming liquid pressure, and the closure flap is moved to the closed position.  When the tank is filled, the source of liquid petroleum gas is shut off and any pressure trapped within the control valve and working against the closure flap is re-leased through a bleeder hole.  Then the spring returns the closure flap from the closed position to the open position.

Abstract: A SLIDER WITH A BUILT-IN LOCKING DEVICE IN A SLIDE FASTENER                   ABSTRACT OF THE DISCLOSURE        The slider of a slide fastener has a locking device built in the front half of the slider body with a key hole open upwardly and a lug for a pull tab composed of upright leg portions disposed at or near the rear and the front ends of the slider body.  At or near the front end, the lug is provided with key guide means leading to the key hole of the locking device.  With this structure of the locking device and of the lug for the pull tab, advantages are obtained in that the slider body is raised always at the leading end of it by pulling the tab obliquely so that the sliding move-ment of the slider is smooth.  The structure is relatively light and enables a reliable connection between the pull tab and the slider.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for indicating a quantity of electrical informa-tion in decimal notation.  An input signal having a voltage level proportional to the quantity to be indicated is compared with a plurality of decimally related reference voltage levels to generate a separate decade enable signal for each reference voltage level.  The input signal and the decade enable signals are utilized to generate a units signal having a voltage level proportional to the difference between the input signal voltage level and the voltage level of the largest reference voltage for which a decade enable signal has been generated.  The units signal voltage level is compared with the reference voltage levels to generate a separate units enable signal for each of the reference voltage levels which are equal to or less than the units signal voltage level.  The decade and units enable signals drive a display which typically includes a plurality of light emitting diodes for indicating the quantity of the electrical information.  This display can have the decades indicating LEDs positioned in a semi-circle and the units indicating LEDs posi-tioned in a straight line for improved readability.

Abstract: IMAGING DEVICE     Abstract of the Disclosure A device for flash imaging, through an imaging mask at an imaging film plane, a dry-process imaging film having a layer of an energy dispersible image forming material on a surface thereof.  The device comprises a solid, electromagnetic energy transmitting body advantageously in the form of a quartz prism having a generally frusto-pyramidal configuration.  The energy transmitting body is associated with a source of electro-magnetic energy, and acts to collect, direct, collimate and shape the energy emitted by the source to provide maximum utilization and substantially uniform distribution of the energy at the imaging film plane.  The device is especially adapted for flash imaging microfiche cards comprised of pre-formed areas or zones of an energy dispersible image forming material, and enables an electromagnetic energy source such as a Xenon flash tube to be operated at lower energy levels for shorter time periods thereby appreciably reducing energy costs and prolonging the useful life of the flash tube, while at the same time pro-viding excellent image resolution in all directions in the imaging film.

Abstract: ABSTRACT OF THE DISCLOSURE Filtering, cleaning and grading apparatus The invention relates to apparatus suitable for filter-ing or washing of lumpy materials, having a rotatable hollow body which is covered at least in part with a filter or sieve.  The hollow body has two sections, the first section having a horizontally or near horizontally arranged truncated pyramid or cone-frustrum type drum rotatable around the hori-zontal or near-horizontal longitudinal geometrical symmetry axis.  Its side is formed, at least in part, by a sieve or filter.  A feeder pipe leads through a smaller end-plate of the drum into the interior, while a larger end-plate has an opening eccentrically arranged in relation to the symmetry axis.  The second section of the hollow body in co-rotation with the first section joins this opening, and has at least three prismatic members connected with each other.  Their sides, at least in part, are formed by a filter or sieve. The geometrical longitudinal axes of the members together form a zig-zag or similar line, intersecting the symmetry axis of the drum, which is the common axis of rotation of the two sections of the hollow body, outside the drum.
