  • Publication number: 20240133194
    Abstract: An enclosure system for a building includes an entryway for the building defined by opposing left and right frame-side jambs and a frame-side transom extending between the left and right frame-side jambs, and a temporary enclosure system removably installable within the entryway. After removing the temporary enclosure system from the entryway, the enclosure system further includes a left door-side jamb attachable to the left frame-side jamb to form an assembled left jamb, a right door-side jamb attachable to the right frame-side jamb to form an assembled right jamb, and a door-side transom attachable to the frame-side transom to form an assembled transom. One or more doors are hung within the entryway and extend laterally between the assembled left and right jambs and vertically to the assembled transom.

  • Publication number: 20240026732
    Abstract: A door system includes a doorframe having opposing vertical jambs, a door pivotably coupled to the doorframe, a threshold extending between the opposing vertical jambs and providing an upper surface that defines a valley, and a dam removably mountable to the threshold at the valley. A valley seal interposes the dam and the threshold at the valley when the dam is mounted to the threshold and thereby generates a sealed interface between the dam and the threshold.

  • Publication number: 20230078998
    Abstract: A door assembly includes a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, a cylinder lock mounted to the second surface at the hole, and a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface. The cylinder dry lock assembly including a main body that defines a central orifice, a low-friction member received within the central orifice, and an actuation mechanism extending from the low-friction member and engageable with the cylinder lock. Actuating the cylinder lock rotates the actuation mechanism, and the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

  • Publication number: 20160236688
    Abstract: A method is provided for controlling a machine having a continuously variable transmission travelling on a ground surface. The method receives signals indicative of an inclination of the ground surface and a payload carried by the machine through an inclination sensor and a payload sensor respectively. The method further includes determining a retarding capability of the machine. The method determines a maximum allowable operating speed for the machine based at least on the inclination of the ground surface, a mass of the machine, the payload carried by the machine and the retarding capability of the machine.

  • Publication number: 20160186857
    Abstract: A method is provided for controlling a machine having a continuously variable transmission travelling on a ground surface. The method includes receiving signals indicative of a speed of the machine and an inclination angle of the surface on which the machine is travelling. The method further includes receiving a shift signal indicative of a desired change in a direction of travel of the machine. The method selectively activates at least one supplementary retarding device based at least on one of the inclination angle and the speed of the machine.

  • Patent number: 8821506
    Abstract: A bone screw comprises an interior channel and at least one opening extending from the interior channel to an exterior of the screw shaft. A head is connected to the screw shaft. A fluid delivery probe comprises an interior channel. The fluid delivery probe is locked to the head so that the fluid delivery probe does not separate from the head under extremely high pressures when a fluid is pumped through the fluid delivery probe and into the screw shaft. Also, a leak-free seal is formed between the fluid delivery probe and the screw shaft so that the leak-free seal does not leak under extremely high pressures when a fluid is pumped through the fluid delivery probe and into the screw shaft.

  • Patent number: 8747411
    Abstract: A fluid delivery and bone screw driver apparatus attaches to a bone screw. An inner sleeve joins a material delivery source connected to one end of the inner sleeve to the bone screw connected to the other end. A removable liner communicates the material through the inner sleeve and into the bone screw. An outer sleeve seals the outer sleeve to the head of the bone screw. Rotating the outer sleeve tightens the seal and rotates the bone screw.

  • Publication number: 20100030135
    Abstract: An improved method and apparatus for anchoring bone screws into bones of living beings includes a cannulated screw or bone anchor that is provided with at least one discharge opening in the distal end thereof. The head of the screw is configured to receive therein a material delivery probe in sealing relationship therewith. A fluid insertion device is connected to the material delivery probe and pumps a highly viscous material through the material delivery probe and into the interior of a bone in which the distal end of the screw has been inserted. The screw can be anchored proximally in bone to prevent backpressure from dislodging the delivery cannula and aides in achieving the high pressures necessary to cause the positive effects of materials previously not injectable in the bone or surrounding areas with the current methods and apparatia.
