摘要:
A sliding door in a van is mounted on tracks for sliding movement between open and closed positions. At the closed position a weather strip is compressed and a door latch is latched. A cable is attached to the door and routed through the vehicle body via pulleys so that pulling the first cable end opens the door and pulling the second cable end closes the door. A motorized drive mechanism includes first and second reels mounted concentrically and having the cable ends wrapped respectively about the reels in opposite directions. A motor drives in one direction rotating the first reel to open the door and is reversible to rotate the second reel to close the door. Each of the reels has a large diameter portion for winding the cable to provide relatively high speed and low force door movement over the greatest portion of travel and a small diameter portion for winding the cable to provide relatively low speed and high force movement of the door during the lesser portion of travel of the door closest to the closed position. The reels have cable set grooves to receive the cable and a spiral ramp groove to connect the large and small diameter portions. A tension retaining spring acts between the two reels to always maintain the cable under tension.

An actuating means for a vehicle body closure latch includes a driver or passenger controlled electric motor driving a reciprocable rack through a gear train. The rack is resiliently biased to a neutral position and shifts an actuator from neutral to an operating position when the rack is moved from the neutral position to a driving position. The actuator is engageable with a latch operator to control movement of the latch bolt to unlatched position when the actuator moves to an operating position. When the actuator reaches the operating position, the actuator is positively stopped to stall the motor or power operator. When the power is removed from the stalled motor or power operator by the driver or passenger releasing a switch, the bias of the resilient centering means returns the rack to its initial neutral or starting position and back drives the motor through the gear train.

A door lock actuator having unlock, lock and superlock modes includes a rotary input member that positions a pivotally mounted output lever in an unlock position, a lock position or a superlock position. The door lock actuator also includes a pivotally mounted superlock lever that has a bypass position and a block position. The rotary input member maintains the superlock lever in the bypass position when the actuator is changed between lock and unlock modes so that the output lever can be moved back and forth between the locked and unlocked positions and moves the superlock lever from the bypass position to the block position when the actuator is changed to a superlock mode so that the superlock lever is moved to the block position to prevent the output lever being moved to the unlock position.

A tool 10 and a method for creating the tool 10 which is comprised of several selectively coupled sectional members 12, 16, and which includes at least one cooling channel 14. In one embodiment, each sectional member 12, 16, which is to be used to form the at least one cooling channel 14, has respective indented channels 18, 20. Channel 18 of member 12 registers with a unique one of the channels 20 of member 16 to which member 12 is coupled, thereby forming the unique cooling passage 14. Other embodiments are disclosed which also provide desired cooling paths 14.

An apparatus and a methodology 200, 350 for producing a tangible item 120 by the use of a plurality of sectional members, such as sectional members 10 and 14. In one embodiment, each sectional member 14 includes a protuberance 16 and these protuberances are selectively nestled to allow the various sectional members 14 to be connected and to cooperatively form a tangible item, such as tangible item 120. In an alternate embodiment of the invention, a first sectional member includes an opening 12 which receives a protuberance 70 from another sectional member. Other sectional members may thereafter be coupled to this assembly by the use of nestled protuberances, thereby allowing the coupled sectional members to cooperatively create a tangible item.

A methodology 40 for producing a laminated tool 10 having desired dimensional accuracy. The tool 10 is produced by the use of several sectional members, such as sectional members 14, 16 which are selectively coupled and which are measured. The measurement is used to determine whether to selectively press these previously coupled sectional members 14, 16 to ensure that their coupled arrangement has a desired dimensional accuracy. Additional measurements and needed pressing operations are accomplished each time a new sectional member is added to the previously coupled sectional member combination.

A mold block includes a tool body with a contoured finished surface adapted to receive a tool insert having a forming surface for forming a bottle neck in a molding operation. The tool body defines an internal channel for heat transfer with the forming surface. At least a portion of the channel is offset generally equidistant from the finished surface to provide a path contoured for conformal cooling of the insert. The tool body has a pair of ports intersecting the channel. Several methods for forming a mold block are disclosed and include machining a contoured finished surface adapted to receive a tool insert on a tool body, forming a heat transfer channel within the tool body, and forming a pair of ports into the tool body. At least a portion of the channel is offset generally equidistant from the finished surface for conformal cooling of the insert.

In one embodiment, a tool for forming an article in a molding operation has a tool body formed from a non-particulate material, with a particulate material bonded to the body. The body provides a forming surface for forming the article. The particulate material, or the particulate material and the tool body collectively provide a duct for conveying a fluid for transfer of heat with the forming surface. In another embodiment, the tool has a tool body formed from a non-particulate material with a cavity and the particulate material is disposed within the cavity. A heat transfer material is disposed in the cavity bonding the particulate material to the tool body. Methods for manufacturing such tools are also disclosed.
