Abstract:
A REMOVABLE CLEAR PROTECTIVE SIDE SHIELD FOR SPECTACLES IS DESCRIBED IN WHICH A SINGLE UNIVERSAL SIDE SHIELD TYPE IS COMBINED WITH ONE OF SEVERAL SHAPES OF SUPPORT SLIDEABLY MOUNTABLE ON THE SPECTACLE TEMPLE SO AS TO GIVE A CUSTOMER CHOICE IN FINDING A SHIELD SUITABLE FOR MOUNTING ON HIS PARTICULAR SPECTACLE DESIGN. ONCE A CHOICE OF SUPPORT HAS BEEN MADE, A SHIELD IS ATTACHED TO THE CHOSEN SUPPORT. SEVERAL ATTACHING MEANS ARE DESCIRBED INCLUDING A MECHANICAL SNAP LOCK THAT PREVENTS SUBSEQUENT SEPARATION OF THE TWO PARTS.
Abstract:
A REDUCED OPERATING TEMPERATURE FOR A SODIUM-SULFUR BATTERY IS ACHIEVED WITH A NEW ELECTROLYTE COMPRISING SODIUM POLYSULFIDE, ALUMINUM SULFIDE OR ALUMINUM POLYSULFIDES AND FREE SULFUR WHEN THE ELECTRODES ARE IN THE CHARGE CONDITION. THE ELECTROLYTE, WHICH HAS A MELTING POINT IN THE RANGE OF APPROXIMATELY 200*C., PERMITS THE BATTERY TO BE SEALED WITH POLUTETRAFLUOROETHYLENE SEALING MATERIALS. BASED ON PRESENT LIMITED DATA, IT APPEARS THAT THE REDUCED MELTING POINT TEMPERATURE OF THE ELECTROLYTE CAN BE OBTAINED WITH SOLUTIONS IN WHICH THE RATIO OF THE MOLE PERCENT OF SODIUM POLYSULFIDE TO THE MOLE PERCENT OF ALUMINUM SULFIDE OR ALUMINUM POLYSULFIDE VARIES CONSIDERABLY.
Abstract:
PATCHES OF ADHESIVE ARE IMPREGNATED INTO BATTERY SEPARATOR MATERIAL, EACH PATCH BEING IN THE FORM OF A CLOSED LOOP INSIDE OF WHICH IS AN AREA OF SEPARATOR MATERIAL NOT IMPREGNATED WITH THE ADHESIVE. ELECTROLYTE IS THEN IMPREGNATED INTO THE AREA INSIDE EACH PATCH OF ADHESIVE, AFTER WHICH THE SEPARATOR SEGMENTS ARE ASSEMBLED INTO BATTERIES WHERE THE ADHESIVE PATCHES SERVE AS SEALS.
PREFERABLY THE ADHESIVE PATCHES ARE NONCONDUCTIVE AND ARE IMPREGNATED ALONG CONTINOUS STRIPS OF SEPARATOR MATERIAL, AND A FURTHER PREFERENCE IS TO ASSEMBLE THE SEPARATOR SEGMENTS INTO THE BATTERIES WHICH ARE STRUCURALLY CONNECTED TOGETHER BY THE CONTINUOUS STRIPS. AFTER ASSEMBLY OF THE BATTERIES THE CONTINUOUS STRIPS MAY BE CUT BETWEEN PATCHES OF ADHESIVE TO OBTAIN STRUCTURALLY UNCONNECTED BATTERIES.
Abstract:
A receiver apparatus adapted to have coupled thereto intentionally transmitted signals, each being characterized as having a predetermined number of pulsations, which are transmitted over a communication link such as the standard switched telephone network and, at times, noise signals which are introduced into the communication link. The receiver includes measuring means arranged to measure the time interval between successive signals coupled thereto, and signal verification means to verify that each signal coupled to the receiver is either an intentionally transmitted signal or a noise signal. In the event that a noise signal is coupled to the receiver, the signal verification means is arranged to abort measurements of the measuring means. Measurements not aborted are indicative of the time interval between each two successive intentionally transmitted signals coupled to the receiver.
Abstract:
AROUND EACH CELL OF A MULTICELL BATTERY IS A WINDOW, BOTH SIDES OF WHICH ARE ADHESIVE. THE ISIDE PERIMETER OF EACH WINDOW, WHICH OVERLAPS A PORTION OF THE INTERCELL CONNECTOR BETWEEN TWO ADJACENT CELLS, PROVIDES A FIRST SEAL AROUND A CELL TO PREVENT LIQUID FROM ONE CELL FROM MIGRATING EITHER OT ANOTHER CELL OR TO THE EXTERIOR OF THE BATTERY. THE OUTSIDE PERIMETER OF EACH WINDOW EXTENDS BEYOND THE EDGES OF THE INTERCELL CONNECTOR TO PROVIDE A SECOND SEAL WHICH ALSO PREVENTS LIQUIDS FROM MIGRATING FROM THE INTERIOR TO THE EXTERIOR OF THE BATTERY. THE WINDOWS MAY BE ELECTRICAL INSULATORS WHICH SERVE THE ADDITIONAL FUNCTION OF KEEPING ELECTRICALLY CONDUCTIVE INTERCELL CONNECTORS AND/OR LIQUID IMPERVIOUS LAYERS FROM COMING INOT ELECTRICAL CONTACT WITH EACH OTHER.
Abstract:
A process is described for the removal of residual nitrate from battery plaques impregnated with cadmium hydroxide by thermal decomposition of the nitrate after the normal impregnation processing is completed.
Abstract:
A STORAGE BATTERY WHOSE CONTAINER HAS HEATING ELEMENTS FORMED ON THE EXTERNAL SURFACES THEREOF. THE HEATING ELEMENTS ARE CONSTRUCTED AND ARRANGED FOR OPERATION EITHER FROM THE VEHICLE POWER SUPPLY OR FROM AN EXTERNAL SOURCE.
Abstract:
Battery electrodes are cycled in bulk in a conductive container by depositing the container in an electrolyte (or alternatively, by depositing the electrolyte in the container) and then passing a current between the container and another conductor present in the electrolyte. The electrodes are then removed from the container and assembled into batteries. Preferably the electrodes are agitated while the current is being passed. Cylindrical rotating containers may be used for the cycling.
Abstract:
A lantern having a cantilevered handle swivelly mounted on the casing of the lantern is disclosed. The handle and casing are moveable relative to each other to any of a plurality of adjusted positions. A portion of the handle serves as a support for the lantern when used as such as well as a lens guard moved to a position in front of the lens of the lantern.
Abstract:
A method for detecting mispositioned parts in assemblies of parts wherein the orientation of one of the parts of an assembly of parts is to be controlled relative to at least one other part in the assembly of parts. The method includes applying a lightreflective-marking pigment to a part whose orientation is to be controlled. The marking pigment is applied to the part at a time when its orientation is known and prior to its assembly with at least one other part of the assembly of parts. An examination of assembled parts is made by a light-sensing device, and by the response of the light-sensing device to the presence or absence of light reflected from the marking pigment, mispositioned parts in the assembly of parts are detected. In particular, the method disclosed is applicable to checking the orientation of storage battery cell elements in their containers.
