Abstract: TOOL-OPERATED FLUSH-MOUNTABLE LATCH   Abstract of the Disclosure A tool-operated latch has a body which is mountable on the back side of a door panel adjacent an elongate opening and a hole formed through the door panel.  An elongate latch lever is pivotally carried by the body and is movable between a latched position wherein the latch lever is nested with respect to the elongate door opening, and an unlatched position wherein the latch lever is extended with respect to the elongate door opening.     A tool-operable actuator is journaled by the door panel hole and by the latch body, and is movable by a specially configured tool between locked and unlocked positions.  A pawl is pivotally carried by the body for movement between a retaining position wherein it engages the latch lever to releasably retain the latch lever in its nested, latched position, and a releasing position wherein the pawl releases the latch lever thereby permitting  he latch lever to be moved to its unlatched, extended position.  The tool-operable actuator provides a cam member which cooperates with the pawl to effect movement of the pawl from its retaining position to its releasing position as the actuator is moved from its locked position to its unlocked position.

Abstract: 43-4578A METHOD OF PREPARING ULTRAPHOSPHORIC ACID ABSTRACT Ultraphosphoric acid containing a phosphorus to hydrogen ratio of greater than 1 can be prepared by bringing together in a reaction zone elemental phos-phorus and a sufficient amount of oxygen in a free-oxygen containing gas to form phosphorus pentoxide, and a sufficient amount of water to form ultraphos-phoric acid. The mole ratio of water to phosphorus pentoxide is maintained less than 1:1. Heat is removed from the product stream of the reaction zone to condense at least some of the ultraphosphoric acid which is then collected. In the preferred embodi-ment, a heat exchange fluid such as pressurized water is circulated through a cooling coil positioned to remove heat from the product stream of the reaction zone. The ultraphosphoric acid can be combined with water to provide polyphosphoric acid.

Abstract: RCA 76,288 ABSTRACT OF THE DISCLOSURE         A high voltage generator of a television display is responsive to an alternating voltage, such as a retrace pulse voltage, for developing an ultor voltage at an ultor terminal.  A protection circuit for the high voltage generator includes a comparator that develops a television display disabling signal when activated.  A circuit that develops a sense voltage representative of the ultor voltage is coupled to an input terminal of the comparator so as to develop the disabling signal when the ultor voltage exceeds a predetermined level.  To provide an overload disabling capability, an ultor beam current sensing circuit is coupled to the input terminal of an operational amplifier. The output terminal of the amplifier is coupled to a bias voltage source and to an input terminal of the comparator. When the ultor beam current exceeds a predetermined level indicative of high voltage generator overload operation, the operational amplifier applies the bias voltage to the comparator input to energize the comparator into developing the disabling signal.  The magnitude of the bias voltage is such as to activate the comparator in substantial independence of the value of the ultor voltage sense voltage.

A high voltage protection circuit includes a comparator that, when activated, disables normal television display.  A sense voltage representative of the ultor voltage is coupled to an input terminal of the comparator so as to activate the comparator when the ultor voltage exceeds a predetermined threshold level.  A sense voltage representative of the ultor beam current is also coupled to an input terminal of the comparator so as to vary the threshold ultor voltage level at which the comparator is activated in accordance with beam current variations. When the ultor beam current exceeds a level indicative of high voltage generator overload, a switch that is coupled to an input terminal of the comparator  changes states to activate the comparator and shut down the high voltage generator.
