  • Patent number: PP8266
    Abstract: A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive double long-lasting blossoms which are Cream Yellow shaded with Buff Orange in coloration. The blossoms are very stable and maintain their coloration well throughout the blooming process and possess a slight fragrance. The plant exhibits an upright growth habit, forms vigorous vegetation, and is particularly well suited for cut flower production since it exhibits an excellent ability to be forced under greenhouse growing conditions. Additionally, the plant exhibits excellent disease resistance.

  • Patent number: PP8273
    Abstract: This new Poinsettia cultivar, designated `268 Marble`, is a vigorous plant with large, erect, bicolored pink and white flower bracts. Cultivar `268 Marble` is a sport of the red bracted cultivar `268` (U.S. Plant Pat. No. 7,275). `268 Marble`, like its parent `268`, is unique because the flower bracts remain erect and do not droop, even after commercial shipping and handling or as the flowers mature. It always looks "fresh" which adds to its beauty and increases its value as a consumer product. Poinsettia `268 Marble` has the same flowering response time and cultural requirements as its parent `268`.

Opposite end panels of the plurality are attached, respectively, to the door and casing on the side opposite the hinge, while inner panels of said plurality are articulably connected with the end panels and with each other in such manner that, when the door is closed, the panels automatically fold to lie in close proximity to the door so that the shield appears to be an integral part of the door trim.

  • Patent number: 5220709
    Abstract: A device (10) to assist manual tightening of a rope passed over a load on a vehicle. In use, the device (10) is first attached to the rope by passing the rope from the upper side of the device (10) through guide (12) to the lower side, then passing the rope up into the lower notch (15) and over the upper side of the device (10) and into the upper notch (14) so that pulling the rope downwardly will secure the device (10) to the rope. Tensioning may then be achieved by forming a loop in a portion of the free end of the rope, passing the loop around a fixed anchorage site on the vehicle and locating a portion of the loop over the pair of arms (16) and (17). The free end of rope is then passed behind and over the portion of rope extending between the pair of arms (16) and (17) and pulled downwardly, thereby urging the rope that extends between the pair of tensioning arms downwardly and causing tension to be applied to the rope. The taut rope is then secured by tying the free end thereof to a fixed anchorage site.

  • Patent number: 5220710
    Abstract: A clamping assembly constructed to hold an electrical cable or tube in a fixed position includes retaining and clamping members. A first surface of the retaining member, which may be made from a compliant material, has raised and lowered portions in a particular pattern. One end of the retaining member has a face transverse to the first surface of the retaining member with raised and recessed portions defining a mating relationship with the raised and recessed portions on the first surface of the retaining member. The clamping member may be made from a springlike material and may be disposed in an open loop in an unconstrained relationship. The clamping member may be disposed in a longitudinal slot in the retaining member so as to be encased by the retaining member. The retaining member may be slitted to communicate with the slot for facilitating the disposition of the clamping member in such slot.

  • Patent number: 5220712
    Abstract: A component with an unlock mechanism is unlockably locked with respect to another component by a resilient snap tooth engaging in a hole defined in the other component. To unlock the components from each other, the unlock mechanism is pulled between the components to force the snap tooth out of the hole against its resiliency. The unlock mechanism has a slant surface that slides against a slant surface of the snap tooth to displace the snap tooth out of the hole in response to the movement of the unlock mechanism.

  • Patent number: 5220713
    Abstract: An improved apparatus for interconnecting safety belts includes a buckle member which receives a tongue member to interconnect the safety belts. An indicator and ejector assembly has a visually readable indicia which changes from red to green as the tongue and buckle members are interconnected. As the tongue and buckle members are disconnected, the indicia changes from green back to red. The indicia is disposed on an indicator member which transmits force to eject the tongue member at least partially from the buckle member as the tongue and buckle members are disconnected.

  • Patent number: 5220714
    Abstract: An apparatus for removing a residual roving attached to a roving bobbin to obtain a blank bobbin, including a rotary driving device for rotating the roving bobbin alternately in a forward direction and a reverse direction, and a device for completely removing the residual roving strongly attached to a roving wind assisting cloth provided on the blank bobbin. A suction nozzle for sucking the roving bobbin is moved to a position where a tip of the suction nozzle comes close to the roving wind assisting cloth, so that the residual roving strongly attached to the cloth can be completely removed by the suction nozzle as rotating the roving bobbin.

  • Patent number: 5220716
    Abstract: Tools for the disassembly of a universal joint comprise two embodiments, a pull-type tool and a push-type tool. In the pull-type tool, a pulling force is exerted on a yoke member other than the yoke member from which a journal bearing is to be removed, an opposite pushing force is exerted on that end or collar portion of the yoke member containing the journal bearing to be removed, and a cylinder/piston combination interposed between the pulling assembly and the pushing assembly operates to cause the exertion of the pulling and pushing forces, so that the journal bearing is forced out of the collar portion adjacent to the pushing assembly. With respect to the push-type tool, a cylinder/piston combination is mounted on a pushing or support assembly, and the cylinder/piston combination is operated to force the piston downward so as to exert a pushing force via the pushing assembly on the universal joint cross, thus forcing the far side journal bearing out of its yoke member.
