A free-standing frame for a photo, a printed painting or any other sheet having decorative or informative data to be displayed. The frame is formed by a pair of superposed flexible plastic panels, at least the face panel being transparent, the sheet to be displayed being sandwiched therebetween. Threaded through holes in the panels is a cord which in the flat state of the frame has overlying the face panel a pair of parallel vertical cord sections on either side of the sandwiched sheet, and a pa...

The present invention relates to a floor standing treatment device that has a front panel and a mainframe assembly adapted to be removably attachable to the front panel. The mainframe assembly has an integrally molded latching mechanism having a latch and one or more L shaped guides configured to cooperate with one or more pairs stops for limiting lateral movement of the latch. The latch is adapted to engage a portion of the front panel for securely attaching the front panel to the mainframe ass...

An upright, self-standing paint roller formed of a stiff wire bent into a roughly squared U-shape, with one leg being about twice the length of the other and extending through the center of and rotatably supporting a paint applying roller, with the other, short leg having an integral long handle forming extension portion extending roughly parallel to the base of the U-shape, and a support member secured to said base near the bend between the base and short leg so that the paint roller may be sup...

An interlocking roofing panel is disclosed. The panel has longitudinal edges and large and small dikes extending along these edges. These dikes interlock to form a standing seam. Upon installation, the top wall of the small dike is sufficiently spaced below the top wall of the first dike of an overlapping longitudinally adjacent panel, defining an "upper gap," to interrupt movement of water between the dikes. Also, the small dike features a concave portion which opens towards the primary panel p...

The standing current in series connected complementary transistors of a push-pull power stage is stabilized against fluctuations in temperature, supply voltage and/or changes in component use, by placing a current resistive element in series with the transistors in the path of the standing current. Voltage variations are developed across the resistive element in response to changes in the standing current caused by one more of the fluctuations. An electrode of an auxiliary transistor is connecte...

A free-standing package of the blister type includes an article containing enclosure formed of a single piece of self-supporting plastic material. The enclosure is in two mating sections integrally joined along a fold line traversing what becomes the base of the completed package. The free edges of the sections have flanges which meet when the sections are closed to envelop the article and the sections are sealed together along the flanges. At the same time, the initially folded base portion is ...

The apparatus is a child's stroller that maintains all the wheels on the ground while it is being folded. The rear legs are interconnected with but separated from the armrests and move on circular paths, the centers of which are pivot points on the armrests. Therefore, the tops of the rear legs move around to a height different from the position of the front leg pivot point, and the location of the tops of the rear legs are determined by the position of the attached wheels rather by the pivot po...

A system and a method for determining the impedance of a given microwave device by measuring the standing wave in a transmission line is disclosed. A section of transmission line having a plurality of field-sensing probes therein is disposed between an RF signal source and the device. The output signals of these probes are sampled by the system, and the device impedance in terms of the reflection coefficient and the standing wave ratio are calculated using a mathematical process and a digital co...

An apparatus for in-situ baling of trees is provided. The apparatus includes a first frame which supports a rotatable second frame. A tree trunk is inserted into the first and second frames. The second frame is rotated by a motor as the frames are elevated toward the top of a tree. During elevation, string is dispensed from a cannister on the second frame, baling the tree. The dispensed string is then secured completing the operation.

A free-standing outdoor enclosure is disclosed. The enclosure includes a frame having a lower section that engages the ground, a side section mounted to and extending upwardly from the lower section and a roof section attached to the side section. The side section includes a plurality of elongate support segments that are arranged about the periphery of the enclosure. The roof section has a like plurality of elongate, flexible support elements interconnected in a radial arrangement. A distal end...
