Abstract: ABSTRACT            A device for applying lengths of adhesive coated tape from a supply length of tape to seal boxes driven along a path past the device.  The device includes an application roller initially positioned in the path and supporting an end of the tape for contact by a box to adhere the tape to its leading surface.  The application roller is mounted so that, subsequent to such contact, it will be revolved against the bias of a spring and will roll over tape being pulled from the device to press the tape against the surfaces of the box as the box is driven further along the path.  Cam and ratchet mechanisms operated by movement of the application roller manipulated a pinch roller (1) to engage and hold and end of the tape on the application roller prior to contact by a box, (2) to move around an edge of the tape being applied and re-engage the tape on the application roller in advance of the portion of the application roller adjacent the box subse-quent to engagement of a box with tape on the contact roller and before a knife on the device severs the tape between the application roller and the box, and (3) to hold the tape against the application roller as the spring returns it to its contact position subsequent to operation of the severing means, while the pinch roller moves along the tape on the roller to engage the newly severed end.

Abstract: FUSE HANDLING TOOL       ABSTRACT:  Disclosed is a tool for removing and installing fuses in metal-enclosed switchgear.  The switchgear includes one or more fuses and one or more isolating switches and operating mechanisms for isolating the fuses from a high voltage supply circuit.  The fuses are mounted between disengageable contacts that connect the fuse between the supply circuit and a load circuit.  Access ports are provided through a front panel of the switchgear and are aligned with the fuses for providing access to the fuses. A tool receiving recep-tacle is mounted on the front panel around the access ports.  The tool comprises a hollow metal housing having a hollow interior and having a flange on one end for being received and retained by the receptacle.  The receptacle aligns the hollow interior of the metal hous-ing with the access port, and makes grounding connection from the housing to the front panel.  The tool also comprises an operating portion including a handle mounted on one end of an insulator.  Mounted on the other end of the insulator is a fuse engaging arrangement that en-gages the end of the fuse when the engaging arrangement is placed against the end of the fuse and the operating portion is rotated 180°. Rotation in the opposite direction disengages the fuse.  The operating portion is adapted to be moved within the hollow metal housing so that the operating portion can be moved into the switchgear against the end of the fuse.  The handle is also grounded to the housing so that the handle is at ground potential.          Rotation of the tool also causes the isolating switch operating mechanism to open the isolating switch to isolate the fuse from the high voltage supply circuit so that the fuse can be removed from the switchgear for testing and/or replacement and then re-installed.          Also, the tool can be used to operate auxiliary appar-atus to indicate the condition of the isolating switch and the fuse.

Abstract: DUAL TEMPERATURE CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE         A temperature control system for providing an automatic reduction in the temperature of a room or a house during the nighttime hours which requires only the con-ventional two conductor wiring between the furnace and the thermostat thereby avoiding the necessity of adding to or replacing the existing wiring between the furnace and the thermostat.  A first embodiment of the system includes a temperature responsive element, a heater near the tem-perature responsive element for providing supplemental heating of the element, a conventional furnace control, a clock-operated current control for the heater, and a diode steering circuit for directing one portion of an alternating current waveform through the heater current control and the heater, and another portion of the alternating current waveform through the temperature responsive element and the furnace control for providing independent control of the heater and the furnace control.  The heater provides supplementary heating of the temperature responsive element during the night-time hours to establish an apparent room temperature which is higher than the actual room temperature so that the thermo-stat element will lower the room temperature during the nighttime hours.  A second embodiment of the system includes two temperature responsive elements, one for setting the low temperature and the other for setting the high temperature, a conventional furnace control, a clock-operated switch for activating either the high or low temperature responsive element, and a diode steering circuit for directing one portion of an alternating current waveform through the low temperature responsive element and the furnace control, and another portion of the alternating current waveform through the high temperature responsive element and the furnace control for providing independent control of the furnace by the low temperature element and the high temperature element in accordance with the timer switch. Accordingly, the low temperature responsive element may be set at the desired nighttime temperature and the high temperature responsive element can be set at the desired daytime temperature with each being activated for the appropriate time period by the timer switch.

Abstract: Abstract of the Disclosure A fuel vaporizer for internal combustion engines employs a chamber exposed to and directly below the underside of the engine carburetor and a heater wall at the bottom of the chamber to receive drops of fuel released from the engine carburetor into the intake manifold.  It also includes an apertured wall having an upperside forming the bottom of the intake manifold riser and an underside forming the top of the chamber. The heater wall may be heated by exhaust gases or by-passed water from the cooling system of the engine.          The chamber is shallow so that surface of the heater wall of volume of the chamber will be high enough for rapid evaporation of fuel.  The drops of fuel released from the engine carburetor drop down directly onto the heater wall and fuel vapor flows out of the chamber into the intake manifold.  The apertured wall is not formed with holes in the peripheral area thereof to prevent the drops of fuel from splashing and/or spil-ling out of the chamber into the intake manifold.

Abstract: ABSTRACT OF THE DISCLOSURE A lock for maintaining the pivotal connection between two parts of a pressure-distributing superstructure in a windshield wiper blade assem-bly in which the pivotal connection is effected by providing a pair of outwardly projecting lugs on the resilient side walls of one of the parts which nest in a pair of aligned openings in the U-shaped end portion of the other of the parts. The parts are assembled by deflecting the side walls of the one part inwardly into an open space in the one part to permit the U-shaped end por-tions of the other part to be fitted over the lugs. Thereafter, the resiliency of the side walls urges the lugs outwardly into the openings to pivotally con-nect the two parts. In order to prevent disconnection of the two parts, the lock is inserted into the open space to prevent the side walls of the one part from collapsing into the open space. The lock has enlarged portions to retain the lock within the open space which has been adapted to receive the lock. The enlarged portions of the lock have been formed to provide camming sur-faces which facilitate insertion and removal of the lock into and from the open space. The lock is also pivotally connected within the open space to permit the lock to swing between are operative position preventing disconnection of the two parts and an in operative position permitting disconnection of the two parts.

Abstract: Abstract of the Disclosure Phosphate ore matrix is treated to recover P2O5 values.  The matrix may be the phosphate ore as it is mined, or it may be residue formed upon dewatering benefication slimes.  Without being subjected to beneficiation, this matrix is slurried with an organic solvent in a slurry vessel.  When the slurry is mixed with a strong mineral acid, a system having a single liquid phase is formed with the organic solvent serving as a vehicle for distribution of the mineral acid which in turn solubilizes P2O5 values for their extraction from the matrix.  Thereafter the P2O5 values are separated from the solid phase and then removed from the organic solvent.
