Abstract: An exterior room for a trailer in which front, rear and side panels cooperate with an external frame connected to the trailer body to provide an external screen room. The front and side panels are joined at the junctures thereof by zippers to provide entry and exit to the screen room. The front panel is maintained under tension by means of a cable between supports for the side panels. Each of the front, rear and side panels is provided with an envelope at the bottom thereof which contains a watertight container. Water in the watertight container provide ballast to prevent the panels from flapping in the wind.

Abstract: A device for communicating in which a hollow frustum extending outwardly from a flat base has tabs at the ends thereof for holding a relatively rigid diaphragm having spaced apart apertures therein. A pair of these devices are interconnected by a cord or string, whereby conversation or sound projected into one of the devices is reproduced at the other device. Two devices are molded as a single integral unit and merchandised as an in-pack item with children's breakfast cereals.

Abstract: A device for producing multidirectional visual displays in which a refracting member having a plurality of elongated lens elements and a design member generally parallel thereto are rotated with respect to each other to provide multidirectional visual displays. The refracting member may be flat or arcuate to form spheres or cylinders so long as the design member is complementary in shape. Rotation is generally provided to the design member.

Abstract: A door closure apparatus is provided for automatically closing a bifold door of a storage cabinet for combustible materials in the event of elevated temperatures. A guide assembly hingedly mounted on the free end of the folding door includes guide fingers which ride along a guide path in a channel guide track at the top of the cabinet. At one end of the track there is mounted a bracket slidably carrying a latch member movable between a latching condition in the guide path and a release condition out of the guide path. The latch member is normally held in its latching condition by a spring and fusible link combination which override a smaller spring urging the latch member toward its release condition. Upon melting of the fusible link the latch member is moved to its release condition by the smaller spring. The latch member is shaped to permit the guide member to cam past it as the door moves to its open position but prevents return movement of the guide member to hold the door in its open position.

Abstract: There is disclosed a trophy plaque comprising a slightly flexible plastic base adapted to be supported in an upright position and having an obverse surface with a recess formed therein. A decorative member is adapted to be press-fitted into the recess, the decorative member in turn having a second recess in its front face for receiving therein an adhesive-backed indicia label covered by a lens press-fitted into the second recess.

Abstract: A system for introducing a predetermined amount of particulate matter to a continuous flowing stream of material. The system consists of a hopper connected via a tube having a screw drive positioned therein to a flowing stream of plastic material to be injection molded or extruded. The hopper and tube are constructed and arranged so that dye material in the hopper contacts only the hopper and the inside of the tube, thereby facilitating easy changing of the hopper and tube to permit the introduction of a different colored dye to the plastic material to be injection molded or extruded. The motor mechanism used to drive the screw can be swung out of the way to permit motors to be changed and also to permit the easy changing of both the hopper and the tube containing the screw drive.

Abstract: A multisport practice device for defining a target for and arresting the flight of a ball or other projectile includes a base supporting a pair of laterally spaced-apart upright posts carrying a net closing the space therebetween. Adjustable crossbar members carry eyelet screws for removably hanging the crossbars from vertically spaced-apart hook screws on the upright posts to define a variable-height target area.

Abstract: A charging bar for loading or reloading small arm type shells or cartridges. The charging bar comprises adjustment means for incrementally varying the volume of a powder or shot measuring chamber of the charging bar. Such adjustment means may include a rotational means which causes the volume of the measuring chamber to increase when rotated in one direction and the volume to decrease when rotated in the opposite direction.

Abstract: Scarifying or abrading apparatus is designed for attachment to a hand-operated single-shaft rotary floor maintenance machine, the apparatus including a circular attachment plate having a plurality of pairs of radially spaced-apart rectangular holding members, there being rotatably mounted between the members of each pair of members a plurality of cutters disposed for rotational scarifying engagement with the floor when the disc is rotated by the machine.

Abstract: A load spacing mechanism for a load conveyor in which an actuating member is mounted on the conveyor and pivotable between an extended position and a retracted position. The actuating member is connected by linkage to a support mechanism which in one position thereof supports a stop mechanism in the raised position, thereby to stop a load on the conveyor from advancing toward the actuating mechanism. When a load is lifted from the actuating member, the linkage operates, as the actuating member moves to the extended position thereof, to move the stop support away from the stop thereby permitting the load at the stop mechanism to force the stop mechanism downwardly and pass thereover toward the actuating mechanism. All of the actuating mechanism, the stop mechanism and the support mechanism are pivotly mounted to the conveyor thereby obviating the need for toggle mechanism and enabling the foregoing load spacing mechanism to operate with either heavy or light loads without adjusting the mechanism.

Abstract: The pen comprises an elongated housing having a light aperture at one end. A plurality of light-emitting diodes is mounted in the housing, and means are provided for focusing the light from such diodes at the light aperture. In use, the pen is held against a coded label and moved therealong. Light from the light-emitting diodes strikes the coded information, so as to produce a light pattern. Lenses in the housing focus the reflected light onto a detector which produces electrical signals in accordance with the light pattern.

Abstract: An improved method of relieving severe itching associated with conditions such as Hodgkin's Disease, mycosis fungoides, intractable pruritis and the like comprising administering an effective dosage of naloxone to a patient suffering from such itching.

Abstract: A toy object such as a submarine or the like with a ballast chamber and an air chamber dimensioned such that normally in a static position the body floats in water with only a small portion of the body extending out of the water. The ballast chamber is filled with water and the air chamber is buoyant and causes the top object to float. Diving planes extend outwardly from the body such that when a motor is activated the toy moves forward, submerges and stays submerged so long as there is forward motion. When the motor stops the toy object rises to its static position.

Abstract: A one-piece seamless unidirectional rotary knitted anti-embolism stocking comprises a seamless tubular body integrally knitted and having varying lengths of yarn in the courses thereof resulting in a varying cross section such that the circumferential tension of the stocking decreases from the toe end to the upper end thereof. Specifically, constant cross section portions are interconnected by transition portions of gradually varying cross section in a pattern to produce on the wearer's leg a pressure which decreases substantially uniformly from the ball of the foot to the top of the stocking. Each end of the tubular body has a two-ply welt portion, and a heel patch is inlaid in the foot portion of the tubular body. The toe end of the tubular body terminates in a toe portion which is folded back on itself and seamed at the side edges of the fold.
