029522100 | Radially expanding part in cavity, aperture, or hollow body | 43 |
20090070984 | METHOD AND DEVICE FOR MECHANICAL COUPLING - A coupling between a device and a mating part includes an elastic material and perhaps a tensioner coupled to the elastic material. The elastic material is wrapped around at least part of the device. The tensioner or other method is used to stretch the elastic material, thereby reducing the thickness of the elastic material. With the thickness of the elastic material reduced by the stretching, the device is inserted into a hole in a mating part. Then the tension on the elastic material is removed, allowing the elastic material to increase in thickness, so as to fill at least part of the gap between the device and the mating part. The coupling may act as an effective heat transfer device for transmitting (by conduction) heat produced by the heat-producing device, to the mating part, which may act as, or be thermally coupled to, a heat sink. | 03-19-2009 |
20090199390 | Article for preventing items from falling behind furniture - The device prevents the loss of articles otherwise susceptible to falling behind furniture, appliances, fixtures or equipment or other large objects placed next to a wall which are not easy to move or reach under such as, but not exclusively, couches, wardrobes, desks, washers, dryers, refrigerators, filing cabinets and dressers. The compressible and flexible device is fitted from above into the crevice between the furniture and the wall. It is held in place by friction created by the pressure caused by the deformation of the device between the furniture and wall. The device, when flexed or compressed, creates a u-shaped channel which catches valuables such as jewelry, makeup, currency, papers, office supplies or other items which are left on top of furniture and which without such invention, may otherwise fall behind the furniture where it would be difficult or impossible to retrieve. Because it uses pressure and friction to maintain its placement, the article does not require fastening by means to the wall or furniture, so it does not damage the furniture or wall. Objects which are caught in the device can be removed easily by the user with the need to remove the article from the crevice. | 08-13-2009 |
20090293258 | Anchor insertion rod - An anchor insertion rod is disclosed for use with an anchor insertion tool removable secured therein for the installation and setting of anchors.

Upper and lower stop members are positioned on the insertion rod, along with a slide hammer surrounding a portion of the insertion rod that moves along the insertion rod between the upper and lower stop members. To install an anchor, the insertion rod is raised to align an anchor within the anchor insertion tool with a pre-drilled hole in the surface in which the anchor is to be mounted. The slide hammer is moved to forcibly contact the upper stop member to impart an impacting force to insert the anchor. The anchor is set by moving the slide hammer to contact the lower stop member and impart a setting force to the lower stop member. Once the anchor is set, handles on the insertion rod are then rotated to disengage and separate the anchor from threaded engagement with the insertion rod and the anchor insertion tool. | 12-03-2009 |
