Abstract: ABSTRACT OF DISCLOSURE         Disclosed herein is an automatic fluid filling device for maintaining fluid at a desired level in one or more battery cells each having a cell opening.  The device comprises a plurality of members each removably insertable into a battery cell, and each including wall means having a first portion sealingly engaging a battery cell opening and also having a second portion located above the first portion, which second portion partially defines a generally air-tight chamber located above the battery cell opening, which second portion also includes an aperture and a removable cap which sealingly engages the aperture for allowing access to the fluid in the battery cell.  The wall means further includes a third portion which partially defines a passage located below and in communication with the chamber and in communication with the battery cell for affording fluid flow from the passage to the battery cell. Each member also includes a fluid level control tube having an upper opening extending into and being in communication with the chamber and having a lower opening extending into the battery cell to the general level at which the fluid is desired to be maintained in the battery cell.  Conduit means can be provided for connecting together the member passages in series, along with a reservoir connected to an end one of the series of connected passages for affording fluid flow through the passages and into the battery cells.

Abstract: LOOP EXTENDER                 Abstract of the Disclosure A loop extender is used in conjunction with a pair of telephone lines extending from a telephone central office to a subscriber location in order to insert a booster DC potential on the telephone lines in such a manner as to aid the flow of DC current produced on the telephone lines by a telephone central office battery.          A control circuit has one input terminal coupled to one of the telephone lines and a reference terminal, another input terminal coupled to the other telephone line and the reference terminal, and an output terminal coupled to a relay.  Whenever the input terminals are supplied with a specified potential from the telephone lines, an output from the output terminal maintains the relay in a nonenergized condition so that contacts controlled by the relay couple  a DC booster power supply in series relationship with one of the telephone lines.  In response to different potentials on the input terminals, the output at the output terminal energizes the relay such that the contacts insert the DC booster power supply in series relationship with the other telephone line. The DC booster power supply has a current sensor such that the booster DC potential is only supplied to the telephone lines when DC current is present on the telephone lines.  In addition, the DC booster power supply has a current limiter limiting the amount of DC current on the telephone lines.

Abstract: ABSTRACT OF THE DISCLOSURE       Support arrangement for supporting side frame of a vehicle bounding a loading area thereof. Two L-shaped supports each have a first leg adapted to be upstandingly disposed outside and adjacent one of the side frames. A second leg is for horizontal mounting adjacent the under side of the loading area. A single double acting pressure medium cylinder mutually connects the two L-shaped supports to enable a horizontal displacement of the latter to be brought about towards and away from each other. Two additional double acting pressure medium cylinders each have a piston rod adapted to be pivotably mounted at its outer end adjacent the under side of the loading area. A guide arrangement provides a pivotable mounting for an and of the cylinder remote from the outer end of its piston rod and is connected to and spaced below the horizontal second leg of each of the L-shaped supports. The additional pressure medium cylinders are thus able to effect individual pivoting of the supports about a horizontal axis while allowing unhindered horizontal displacement of the supports with the letter in arbitrary pivotal positions.

Abstract: APPARATUS FOR TESTING THE REFRACTIVE         POWER(S) OF LENSES                            ABSTRACT       The refractive power(s) of a lens which may possess cylindrical power are determined by retro-reflecting a particular target image through an optical system and varying the axial positioning of one or more elements in the system to bring the reflected image to one or two clear and unambiguous foci at a target plane.  By employing a small, intense diffraction image as the target image and further detecting only reflected light passing through a pinhole area on the optical axis at the target plane, a single significant light energy peak is observed at system focus for a lens possessing sphere power only and two significant light energy peaks appear at the respective foci of the principal meridians if the lens also has cylinder power. Means are provided for recognizing the existence, number, and/or relative size of light energy peaks and for correlating their occurrence with the position of the movable element in the optical system to determine respective refractive powers of the test lens.

Abstract: ABSTRACT OF THE INVENTION         Volatile borates and/or fluorides are removed from the hot stack gases of a glass furnace by passing the hot stack gases up through a layer of wet pellets containing ions of an alkaline earth metal or an alkali metal.  The pellets may contain solid borates and/or fluorides as part of the feed to the glass furnace, and still absorb volatile materials from the stack gases, so long as the borates and/or fluorides in the pellets are in, or are converted to, a less soluble and volatile form than are the volatile materials in the stack gases.  Ca(OH)2 is a preferred material for converting the volatiles into an essentially nonvolatile form. Ion exchange materials, such as clay, can also. he used to capture these volatiles.
