Abstract: ENERGY-RECYCLING SCISSORS LIFT     ABSTRACT OF THE DISCLOSURE         A scissors mechanism supports a platform, and is coupled to a sealed gas cylinder or other energy-storage device in such a way that the cylinder tends to lift the platform, and an article on the platform -- such as a television set, a bar, office equipment, a tabletop, etc.          The lift may be enclosed in a compact cabinet so that the article on the platform is concealed when down, and accessible when up.       Energy released in lowering the article is stored in compression of gas within the storage device, and subsequently reused in raising the article.  Compensation is provided for the strongly varying mechanical advantage provided by the scissors mechanism, so that the stored energy can operate smoothly on the article throughout the entire operating range of the scissors, making possible the use of the energy-recycling system.       In one embodiment the stored energy alone is made capable of raising the article through the entire range of the mechanism, but the article can be easily lowered by manual application of light downward force -- even though, for mechanical simplicity, the energy-storage device remains connected to raise the article.       In another embodiment this manual application of controlling force is replaced by a remote-control actuator, such as a small motor or a small hydraulic or pneumatic cylinder.  Such a remote-control actuator applies pilot forces upward or downward to control the direction of operation, while the sealed gas cylinder generally bears the weight of the platform and the article on it.

Abstract: ABSTRACT OF THE DISCLOSURE           A particle fuel burning furnace has an upper combustion chamber for holding a pile of particle fuel and  burning  the  same  from  the  bottom  thereof.  The furnace  also  includes  a lower combustion chamber for afterburning combustible gases given off by the burning of  solid  fuel  in  the  upper  chamber and a series of spaced apart vertically-extending passageways arranged in a  row  and  interconnecting  the  upper  and  lower chambers for communicating the combustible gases from the upper to the lower chamber. A first improved feature relates to a particle fuel delivery control device which operates  an auger for filling the upper chamber with particle fuel  to a desired level. A beam of light is transmitted and reflected between a photoelectric cell and  reflector  respectively  of  the  device.  When  the particle fuel pile has grown in height during filling to the  desired level  the  light  beam  is  interrupted and filling is terminated. A second improved feature relates to  a particle  fuel  diversion structure positioned in spaced  relationship  above  and  overlying  the  row  of passageways. The structure forms a horizontal slot which extends  laterally from the passageways which prevents particles of fuel from falling through the passageways and relocates  the flame which burns the particle fuel pile  from  the  bottom  to  a region  away  from  the passageways.

Abstract: Method and Apparatus for Applying Sealant to Insulating Glass Panel Spacer Frames Abstract Partially assembled spacer frames formed by a plural-ity of joined spacer frame segments are advanced past a sealant applying station defined by first and second sealant extrusion nozzles positioned for applying sealant to opposite spacer frame segment sides and a third sealant extrusion nozzle positioned for applying sealant to the exterior spacer frame side.  Extrusion nozzle controllers render the nozzles operative to apply sealant to the spacer frame segments in response to control signals. A spacer frame detection system produces signals indicat-ing the presence of the spacer frame at the sealant application station.  A signal processor coupled to the detection system and to the nozzle controller produces control signals for intermittently operating the third extrusion nozzle in response to the presence of the leading end of the spacer frame segments at said station, and the approach of the junctures of subsequent spacer frame segment ends and the trailing frame end.  The signal processor also provides signals for operating the first and second nozzles continuously while the spacer frame is at the station.

Abstract: ABSTRACT OF THE DISCLOSURE     A two piece dispensing closure for a container in which one piece is a cylindrical cap which is attached to the container by thread  molded in the inner surface of a skirt portion of the cap cooperating with complementary threads on the neck of a container.  The first piece of the closure is a cap which has an orifice or nozzle opening through which the contents of the container is dispensed. The second piece of the closure is a lid which acts to close the dispensing opening.  A plug on the lid engages the dispensing opening on the cap to sealingly lock the lid and cap together.  A hinge is formed in the cap and lid in a manner permitting the closure to be taken apart for cleaning and to be easily reassembled.  The cap has a pair of upward-ly extending posts having facing spherical projections. The lid is provided with a pair of complementary slots to receive the posts and complementary spherically concave indentations to receive the projections on the posts. This hinge permits movement of the lid between an open and a closed position with friction retaining the lid in any intermediate position. No portion of the hinge projects from the cap which facilitates easy-handling and allows the closure to be formed in a symmetrical manner improving the appearance over a projecting or cut-away hinge design.

Abstract: INTERLOCKING ROOF TILE            ABSTRACT OF THE DISCLOSURE            The present tile is adapted to cooperate with similar tiles to form a tiled surface, and is formed from a relatively thin sheet having a periphery disposed symmetrically about a central axis. When the tile is installed the central axis coincides with a line defining free water flow down the tile between upper and lower tile portions. The tile has first and second raised ribs extending symmetrically as mirror images of each other on each side of the central axis. Each rib has upper and lower rib portions which are interconnected so as to extend continuously between the upper and lower tile portions to increase stiffness of the tile. The stiffened tile is better able to resist weight of a person walking on the roof, and also resists a tendency for the lower portion of the tile to lift when wind blows onto the roof. The upper rib portions are smaller than, and complementary to, the lower rib portions so that the lower rib portions of an upper tile can fit over upper rib portions of a lower tile. When so fitted, the edges of the tiles are interlocked and this increases accuracy of installation of the tiles, as well as reducing a tendency of water seepage past edges of the tiles.
