Abstract: Abstract of the Disclosure Glass lenses or lens blanks, containing all the ingre-dients necessary to produce phototropic or photochromic behavior, are treated in a conventional production furnace to produce a locally variable heat treatment, wherein at least one portion there-of is raised to a temperature exceeding the glass strain point but not the softening point, and other portions are heated to variable temperature decreasing from the strain point.  The treatment causes development of phototropic or photochromic be-havior only in those portions of the lenses or lens blanks ex-posed to the temperature above the strain point.

Abstract: REINFORCED PAPERBOARD CAN ABSTRACT OF THE DISCLOSURE       A reinforced paperboard can is constructed from a pair of rectangular, superposed paperboard blanks each of which is transversely scored to form side and end walls of the can.  Those panels of each blank which are to constitute the side walls are uniform in size and those panels which are to constitute the end walls also are uniform in area.  Each of the blanks is scored longitudinally whereby flaps are formed along one edge of the panels of one blank and which are separated by slits so as to enable the flaps to form a bottom closure for the can. The other blank has a smaller area than the first blank so that the other blank has tabs of less area than the flaps and which are separated from one another by slits so as to enable the tabs to overlie the flaps.          The can thus produced has double thickness side and end walls, and the closure flaps adjacent the side and end walls also are double thickness.  A top closure for the can may be pro-vided by flaps similar to the first mentioned flaps or by a separate top member which may be crimped to the side and end walls.

Abstract: ABSTRACT OF THE DISCLOSURE              The user of the camera moves an input component to supply film-transport force. A rotary transmission transmits film-transport force from the input component to the film in the camera, and includes first and second output components. When the input component is moved, the first output component is arrested and the second non-arrested, and then the second output component is ar-rested and the first non-arrested. A locking structure moves from a locking position arresting the first output component and an un-locking position releasing the first output component. A sensing mechanism responds to film frame advancement by entering into a film perforation, causing the locking structure to move to the un-locking position and causing the second output component to become arrested by the resistance of the film to transport. The transmissio includes a gear driven by the input component and driving the second output component and a displaceable mounting member mounting the gear for both rotation and displacement. The displaceable mounting member constitutes the first output component of the transmission.

Abstract: ABSTRACT OF THE DISCLOSURE             A method of rebuilding the eroded area of an ingot mold such as used in casting steel ingots places a metal producing exothermic compound in a cleaned eroded area of the ingot mold to be rebuilt, ignites the compound and confines the molten metal produced by the exothermic reaction to the eroded area where it forms a welded bond with the metal of the ingot mold and fills the eroded area.  A protective metal coating of a suitable welding rod metal may be deposited by electric arc or flame welding on the metal patch formed of the exothermic material.  This invention is distinguishable from other inventions by reason of the steps of cleaning the eroded ares in the ingot mold,placing a metal producing material including an exothermic compound in the cleaned area and igniting the material, confining the material in the eroded area to restore the ingot mold cavity and its original configuration.

Abstract: ABSTRACT OF THE DISCLOSURE      A system selectively provides a selected program, such as a movie, to viewers who select the program by pushing a button as an attachment to a television set.  The selected program is carried on a standard television channel unused in the area for regular programming having a carrier frequency fc.  This signal is mixed with the second harmonic of the master oscillator at the input of the master antenna TV system to translate the selected program channel to a midband channel between the standard high and low VHF television bands.  The master oscillator  signal is also injected into the input of the MATV system and used for providing remote control of the room box and as an input to a frequency converter which converts the midband channel back to the standard TV channel when the user presses the selector button on the room box.  A command carried by the master oscillator signal produces a pulsed radio frequency signal having a width that signifies the state of the room box in a time slot indicating the room in which the box is located.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure describes a process for the production of an attenuated strain of measles virus effective for the production of an attenuated measles virus vaccine.  The starting material is an Edmonston strain of measles virus which has undergone a plurality of culture passages in various culture media.  A sample of the last culture passage is taken and a plurality of culture passages of the sample is effected in primary cultures of fibroblasts of chicken embryos.  A sample from the last culture passage is inoculated and a culture pas-sage is effected in a primary culture of fibroblasts of chicken embryos thereby obtaining clones of virus.  Clones of measles virus obtained in the last culture passage are isolated and one selects those which are thermosensitive at a temperature between about 32°C and 37°C.  Among the thermosensitive clones which have been selected, another selection is made of the ones with moderate cytopathic effect, and finally one isolates from the latest selection, the one which shows highest seroconversion on monkeys, thus producing an attenuated strain of measles virus.
