  • Patent number: 9522070
    Abstract: An adjustable spinal fusion intervertebral implant including upper and lower body portions each having proximal and distal surfaces at proximal and distal ends thereof. The implant can include a proximal wedge member disposed at the proximal ends of the respective ones of the upper and lower body portions, and a distal wedge member disposed at the distal ends of the respective ones of the upper and lower body portions. First and second linkages can connect the upper and lower body portions. Rotation of an actuator shaft can cause the distal and proximal wedge members to be drawn together such that longitudinal movement of the distal wedge member against the distal surfaces and the longitudinal movement of the proximal wedge member against the proximal surfaces causes separation of the upper and lower body portions.

  • Patent number: 6935893
    Abstract: An electrical connector includes a housing having a front mating end, a rear terminating end and at least one terminal-receiving passage extending in a direction defining an insertion axis extending between the ends. The passage has a rear open end communicating with the rear terminating end of the housing. A TPA device is engageable with the housing at the front mating end thereof in a pre-load position. The TPA device includes a through passage communicating with the terminal-receiving passage in the housing. The TPA device is movable rearwardly from the pre-load position to a locking position. A terminal is insertable through the rear terminating end of the housing into the rear open end of the terminal-receiving passage along the insertion axis and into the through passage in the TPA device. The terminal moves conjointly with the TPA device from the pre-load position to the locking position.

  • Patent number: 6290539
    Abstract: A connector component includes a housing portion and an insert portion. The insert portion includes a plurality of terminal-receiving passages. Conductive terminals may be inserted into the passages, and a ramped fixed shoulder is formed on each passage surface for retaining the terminals in the passage. Additionally, a flexible finger is provided for each passage for holding the terminals in position in the passage. A terminal may be loaded into each passage and disposed in front of the shoulder. The housing portion of the invention includes a generally box-shaped casing having a hollow cavity for receiving the insert portion of the invention.

  • Patent number: 6234826
    Abstract: A connector includes a first housing half and a second housing half, with one of the connector halves being a socket half, and the other connector half being a plug half. A latching mechanism is provided so that when the connector halves are assembled, they are latched together in the assembled position. A CPA device is also provided which is independent of the connector halves. The CPA device may be securely mounted on one of the connector halves prior to assembly of the connector halves. Following latching of the connector halves into the assembled condition, the CPA device may be slid forward to a final position to lock the latching mechanism to prevent the connector from being inadvertently unlatched. Also, if the connector halves are not fully and properly assembled, it is not possible to slide the CPA device into the final position.

  • Patent number: 5385572
    Abstract: A trocar has an elongated shaft, and a cutting element is attached to a distal end of the shaft. The cutting element can be a transparent puncturing head formed integrally with the shaft, and a distal portion of the puncturing head is configured as a regular triangular pyramid having three sharpened cutting edges. Alternatively, the cutting element can be three or four metal cutting blades which are attached to the distal end of the shaft. In either case, a pathway for light communication is established from the cutting element through the shaft, a portion of which is transparent. The shaft has a cavity, and a rigid endoscope is positioned in the cavity to collect light from the distal end of the shaft. A video monitor is connected to the endoscope for displaying an image of the path of advancement of the trocar.

  • Patent number: 4113007
    Abstract: A rapid heat recuperative heat exchanger particularly adapted for use with large gas turbine engines, including a heat exchanger core which is composed of a plurality of spaced plate members. The core is supported within a skeleton framework by hanger members, the lower ends of which are slidably attached to horizontal control rods which extend through aligned openings in the core plates and which guide movement of the plates in an axial direction to the rods due to thermal expansion. Pressurized air is introduced to the core by inlet and outlet fittings on the end of the core which are of significantly greater thickness than the plate members. It is undesirable to join active heat exchange members of widely varying masses and differing cross-sections. Therefore, the end plate of the core is made of material having the same thickness as the inlet and outlet fittings. Progressing from the relatively thick end plate, the plates are gradually decreased in thickness until a desired plate dimension is achieved.

  • Patent number: 4098330
    Abstract: A recuperative heat exchanger for gas turbine engines having an annular configuration with the air and exhaust gases, respectively, passing through the axial faces of the recuperator in counterflow relationship. The recuperator is formed by stacking a plurality of individual plates one against another about a circular form which corresponds to the inner diameter of the annular recuperator. The primary or main body of the plates are involutely curved in the radial direction and an edge extends laterally from this surface. A shoulder formed in the edge engages a portion of the next adjacent plate to space the plates one from another a given predetermined distance. The axially facing edge portions of every other plate is recessed or cut back at a radially inner location to form and inlet an outlet opening for air. Likewise, alternate plates have edge portions which are recessed near a radially outward location to form inlet and outlet openings for exhaust gases.
