Abstract: This invention relates to a device for releasably mounting thin walled cylindrical members in a machine involving rotary working operations, such as rotary screens used in rotary printing presses. The device comprises cylindrical end members adapted to be mounted on the rotary machine and adapted to fit within and engage inner peripheral flanges at the ends of the cylinder. The end members comprise an annular slot which contains a ring member expandible by suitable pressure means. Each ring member contains an outer annular groove adapted to engage the inner flange at each end of the cylinder upon expansion of the ring member thereby securing the ends of the cylinder on each end member. The ring member can be a steel band expandable by the action of a pressurized air tube mounted in the annular slot, or alternatively, the ring member can be an outer wedge ring disposed in the annular slot with an inner wedge ring in the slot which can be axially moved and thus radially moving the outer wedge ring.

Abstract: The invention relates to devices removably mountable by magnetic means on a metallic hood of motor vehicle for deflecting air currents containing bugs, road grime, etc., to prevent contact thereof with the windshield of the vehicle. The deflecting devices generally comprise a horizontal base member containing semi-rigid, flexible, strip, permanent magnet members, and a transparent shield canted backwardly and connected to the base. The device is molded of a semi-rigid, flexible plastic material which permits the shield and base to flex with the air currents produced when the vehicle is in motion.

Abstract: The invention concerns a safety ski binding for the toe and/or heel with a spring loaded holding jaw that pivots around an axle with the other end of the spring attached to the housing which is mounted on the ski.

Abstract: The invention relates to a doll house having an A-frame design, e.g., a doll house typifying a hunting or mountain lodge. The doll house is of the collapsible type having a novel design in its construction. It is constructed of a small number of individual panels which comprise the walls, floors, roof, etc. The panels are provided with grooves and slots so that all the panels slide together easily and support one another. No tools or screws are required for construction and the parts are locked tightly together in a rigid structure by the simple insertion of several small pegs in matching holes provided in the various panels. The doll house has a unique roof assembly comprising two panels, which can easily be removed to expose the interior rooms.

Abstract: The invention relates to a doll house having a unique front wall, which is split and hinged to side walls, and which can be opened to expose the rooms within. The doll house is of the collapsible type having a novel design in its construction. It is constructed of a small number of individual panels which comprise the walls, floors, roof, etc. The panels are provided with grooves and slots so that all the panels slide and fit together easily and support one another. No tools or screws are required for construction and the parts are locked tightly together in a rigid structure by the simple insertion of several small pegs in matching holes provided in the various panels.

Abstract: A buoyant, flexible, resilient aquatic mat for use on water surfaces adapted to support one or more persons. The mat comprises an elongated slab and a headrest formed of the same material. The material of the mat comprises a unicellular, non-water absorbent, plastic foam having a tough plastic coating over the entire surface. The headrest comprises a transverse void which provides additional buoyancy. Several embodiments of the aquatic mat are described, and in addition, a modification applicable to all the embodiments, wherein the void of the headrest is enclosed at both ends to provide a closed air chamber and alternatively, the closed air chamber can have vent holes communicating therewith through the bottom of the headrest.

Abstract: An auxiliary gun sight adapted to be fitted and used around either one barrel or double barrel guns as well as the gun stock. The auxiliary gun sight comprises a cylindrical elastomeric member having three adjacent projecting sights at angles to each other on its outer periphery. The projecting sights are used to provide a lead in sighting and aiming a gun at a moving target. Several modifications are disclosed.

Abstract: Sulfolene, a typical conjugated diene cyclic sulfone, is prepared by emulsifying butadiene in water in the presence of an antioxidant, and thereafter reacting the emulsion with sulfur dioxide under high pressure, for a period sufficient to complete reaction with the butadiene, whereby yields approaching quantitative are obtained.

Abstract: The invention relates to a doll house having columns in the front, e.g., a doll house typifying Mount Vernon, George Washington's home. The doll house is of the collapsible type having a novel design in its construction. It is constructed of a small number of individual panels which comprise the walls, floors, roof, etc. The panels are provided with grooves and slots so that all the panels slide together easily and support one another. No tools or screws are required for construction and the parts are locked tightly together in a rigid structure by the simple insertion of several small pegs in matching holes provided in the various panels. The doll house has a series of decorative columns and fence on the front of the house and a unique assembly thereof is disclosed.
