Abstract: A dolly for attachment to inclined augers of existing manufacture, which allows the auger intake end to be raised from the ground and supported by a caster wheel, using the winch already present on the auger and a telescoping shaft attached from the doily to the auger. If the shaft length is locked and the augers upper end is lowered with the winch, the lower end is raised from the ground, and supported on the caster wheel. The operator can then manually move the auger around the work area more easily.

Abstract: A valve operating system in an internal combustion engine is disclosed, wherein the operational characteristic of an engine valve which is an intake valve or an exhaust valve, can be changed in accordance with the operational state of the engine. In the valve operating system, a power transmitting means comprises an inner wheel, an outer wheel surrounding the inner wheel, and a carrier on which a planetary rotor is rotatably carried. The inner wheel is operatively connected to a cam shaft, and the outer wheel is connected to the engine valve. A rotational-amount control device is connected to the carrier for controlling the rotational amount of the carrier in accordance with the operational state of the engine. Thus, the size of the valve operating system can be reduced, and moreover, the operational characteristics of the engine valve can be finely changed.

Title: Extrusion die
Inventor: HUANG YEN-CHIEH
IPC: B29C48/92
Filed: 1997-05-13
Granted: 2004-08-24
Abstract: An extrusion die (10) includes a die body (30) having an upstream face (32) and a downstream face (34) with an extrusion profile (22) passing through the body (30) from the upstream face (32) to the downstream face (34). The walls of the extrusion profile (22) being the bearing (46) of the die (10). A pocket (40) having tapered sidewalls (70) is formed in the upstream face (32) of the die (10) and surrounds the extrusion profile (22). The configuration of the pocket (40) improves the material flow through the die (10). The configuration of the pocket (40) depends on the configuration of the extrusion profile (22). The width of the pocket (40) is small at the fast areas of the extrusion profile (22) while being large at the slow areas of the extrusion profile (22). The pocket (40) alters the entry angle of material as it enters the die (10) thus reducing friction in the die (10) and allowing increased extrusion speeds. In conjunction with the pocket (40), the die (10) has a continuous bearing (46) having a length depending on the configuration of the extrusion profile (22).

IPC: F27B9/24
Filed: 2000-04-07
Granted: 2007-07-03
Abstract: An apparatus and method for changing pallet cars on-the-fly in a traveling grate machine. The pallet cars have supporting wheels for travel on spaced-apart outer and inner guide rails of the traveling grate machine along a top strand to a bottom strand and along intermediate curved end portions joining the top and bottom strands. The traveling grate machine includes space-apart drive sprockets positioned at one end of the intermediate curved end portions for engaging and driving the supporting rollers of the pallet cars and for causing movement of the pallet cars along the top and bottom strands of the machine. The apparatus for changing pallet cars includes first hinged sections of outer guide rails located at the drive sprockets adjacent to the bottom strand of guide rails. The first sections of hinged guide rails are moved from a locked position to an open position whereby in the open position a selected pallet car requiring replacement is removed from the drive sprocket means and outer guide rails as the drive sprocket continues to turn. Second hinged sections of outer guide rails are provided at the top of the drive sprocket adjacent to the upper strand of guide rails. The second hinged sections of outer guide rails are selectively moved from a locked position to an open position whereby in the open position a replacement pallet car is inserted on the sprocket means and against the inner guide rails in a position previously occupied by the aforementioned first pallet car as the drive sprocket rotates. The second hinged sections of outer guide rails are then moved back into the locked position. The procedure is repeated as necessary to replace damaged or otherwise worn pallet cars requiring maintenance.
