Abstract: METHOD FOR IMPROVING HYDROLYTIC STABILITY OF THE BOND    BETWEEN STEEL SURFACES AND ORGANIC ADHESIVES     ABSTRACT  A method is disclosed for improving the hydrolytic stability of the adhesive bond between an RFL type organic adhesive and the steel reinforcing element in steel-rubber composite articles. This is accomplished by a pre-treatment of the steel surface before it is coated with the organic adhesive. The pre-treatment is conducted in a continuous operation which includes the sequential steps of: (1) cleaning the metal surface by a vapor degreasing method or by immersion in a detergent containing aqueous bath followed by a hot water rinse; (2) coating the surface with a crystalline or micro-crystalline zinc phosphate; (3) rinsing the phosphated steel surface with water; (4) subjecting the phosphated surface to a chromate or chromic acid rinse; (5) rinsing again with deionized water; and finally (6) drying the steel reinforcing element.

Abstract: ELECTRONIC TYPOGRAPHIC APPARATUS     ABSTRACT OF THE DISCLOSURE       An electronic typographic apparatus includes a multiline display, the top of the display being justified and the lower line constituting a data entry line.  Coded typographic data is stored in a character memory, the dot format for the display of charac-ters in different scan lines being produced upon application of stored character data to character generating read only memories.          The data entry position of the data entry line of the display is stored and new data is entered into the character memory with counting circuits being employed to keep track of the data entry line and position. The display is "rolled up" one line upon receipt of a carriage return signal, and in the backspacing function, stored data is deleted.  Backspacing may proceed into a line previously rolled up, in which case all of the lines are rolled down.  The characters are displayed with proportional widths, as a function of a Character Clock signal generated from a read only memory instantaneously responsive to coded signals of the character memory just prior to the display of elements of a character.  Word spaces of the top line of the display are counted to develop justification data for justifying the top display line, the justification data being stored in a separate memory and "stretching" the word spaces of the top display line by inhibiting the character clock, while the display scan continues, for the determined periods.  Once justification is complete, the afore-mentioned determined periods are digitized and directed to the hard copy printing device to define the amount of "stretching"     required.  Tab stops are stored in a separate memory, and a cir-cuit responsive to a tab signal stored in the character memory also inhibits continuation of the character clock signal until a tab stop signal is received from the tab stop memory.              -1a-

Abstract: APPLICATION OF                            JACK ELIAS               BATTERY BACKUP FOR AC POWERED DC SUPPLY              ABSTRACT     A battery backup system for an AC energized DC supply has an AC line monitor for producing a pulse signal having a pulse width dependent on rise time of the AC signal and a frequency dependent on zero line crossings of the AC signal.  The pulse signals are checked for frequency and pulse width by being used to control the charging time of a timing capacitor for a timer and to be compared with the pulse width of a predetermined reference pulse, respectively.  The occurrence of a defect in the pulse signals stemming from either pulse testing criteria is effective to trigger an SCR circuit into conduction to connect a backup battery to the load devices to replace the DC power formerly being supplied by the  AC line.  After restoration of the AC power, the backup battery is removed following a fixed time delay to allow the AC powered DC supply to stabilize.  A battery charging power supply is connected to the backup battery and is automatically switched between a battery "float-rate" and a "high-ratel" charging operation following an AC outage and when the charging current indicates that the backup battery is fully charged.

Abstract: Abstract of the Disclosure Disclosed is a bracket for supporting telephone directory informa-tion or the like, having an upwardly inclined flat portion that is solely supported on one side edge by a downwardly projecting side member.  The lower edge of the side member has a securing device for fitting under and behind the side of a telephone housing and being secured thereto, holding the inclined flat portion in a suspended, projected position for supporting the directory information.  A retainer on the upper end of the inclined flat portion holds the directory information and accepts, but yet positively holds, the directory information in position, by employing a U-shaped member having inwardly compressing surfaces, and in another embodiment has an attachment devices that wedges within the U-shaped member to hold the directory informa-tion in position.  Known devices for supporting directories comprise slide mechanisms that fit under the telephone housing and are pulled forward from underneath the telephone for use but these have the disadvantage of not being effectively within the user's view.  Also they provide little or no support for writing information on paper placed on the directory support.
