Abstract: An apparatus is useful for wrapping a wrapping film over an elongate load, which has a generally cylindrical exterior and two generally circular or generally annular ends.  Two blocker rollers cradle the load with its axis extending horizontally and are arranged for rotating the load about the load axis.  A dispenser mounts a roll of the wrapping film with its axis extending vertically.  The dispenser is mounted on a rotatable arm, which is rotatable about a vertical axis.  A carriage is provided for mounting the dispenser and for carrying the dispenser and the roll back and forth along the cradled load.  Thus, the roll is moved along an oblong path, whereby the film pulled from the roll is wrapped over the near side of the load, one end of the load, the far side of the load, and the other end of the load, as load is rotated.  The roll remains at an elevation above a central portion of the load so as to permit the central portion to remain unwrapped.                                      -

Abstract: A crop harvesting header includes a reel mounted on a pair of forwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes bats with fingers which pivot each about a respective bat axis so the angle of the fingers varies as the reel rotates. The angle of the fingers can be varied to increase and decrease the angle at the knife. The arms include a forward portion which is arranged at an angle to a main portion so as to be inclined downwardly and forwardly therefrom. As the reel supports on the arms is moved forwardly along the arms and engages onto the forward portion, the reel is moved downwardly and forwardly which simultaneously changes the angle to provide a more aggressive action as the reel is moved forwardly of the knife.

Filed: 1996-10-21
Granted: 2001-04-24
Abstract: A communication device locates a wireless service provider in a multi-service provider environment using a frequency band search schedule. The frequency band search schedule has a first or home band and a several other frequency bands in a predetermined order. The order of the frequency bands may be programmed by the user or by a home service provider over the air. The communication device searches for an acceptable service provider by examining the home band and then the other bands listed in the frequency band search schedule. The bands are examined in the order specified by the frequency band search schedule. An acceptable service provider is identified by comparing the identity of a service provider specified by an identifier received from a band being examined with a list of acceptable service providers.

Title: Roofing termination device
Inventor: CHAMBERS ALAN

Granted: 1999-03-30
Abstract: A device (10) for terminating a roof surface at a vertical edge in a waterproof and airtight manner may serve as a flashing strip at a parapet wall, a wall cap, a roof edge, an expansion joint or in other roofing applications. The device comprises a relatively rigid member (12), typically of sheet metal or the like, and a flexible member (14), typically of modified coal tar bitumen, EPDM, or other suitable roofing material. The device has a channel (16) formed in the rigid member alonga longitudinal edge that receives the flexible member in an airtight and watertight manner. In this configuration, the flexible member provides a covering for the fastening surface (24) on the rigid member, which is fastened by conventional means (108) to the roofing surface (100) and the underlying support structure (110). The preferred channel is formed from a pair of longitudinal bends (18, 20) made in opposite directions such that a "Z" shape cross section is formed. The first edge (28) of the flexible member is coated with an appropriate sealant, positioned into the channel and compressed into place. In some applications, at least one portion (90) of the rigid member near the first bend forming the "Z" shape cross section is pressed into the first edge of the flexible member, as achieved by a metal press brake, with the press brake in some instances perforating the rigid member at the point of impressing.

Title: Thermal shield for a gas turbine combustion chamber
Inventor: SCHMID ACHIM
IPC: F23R3/10
Filed: 1995-07-17
Granted: 2006-11-07
Abstract: A heat shield for the head area of a combustion chamber has as usual a through-hole for the burner. A continuous collar with air passage holes projects from the back side of the heat shield at the edge of the through-hole.   Cooling air can flow through the holes into a ring-shaped channel arranged between the heat shield and the burner, then into the combustion chamber. This cool air flow lies as a cool air film on the surface of the heat shield. For that purpose, the cool air flow or cool air film swirls in the same direction as the combustion air supplied through the burner. To generate this swirling motion, the air passage holes in the collar are inclined in the radial direction. The heat shield is further provided with appropriate inclined effusion holes.

Inventor: BOUCHER YVES
IPC: G06T13/40
Filed: 1997-07-29
Granted: 2007-06-26
Abstract: A method of and a system for controlling an inverse kinematics generated animation of an articulated chain is described. A resolution plane in a default orientation is computed by determining a root-effector vector extending from a root of an articulated chain to an end effector of the articulated chain and letting the resolution plane extend through the root-effector vector. A control icon representative of a position relative to the root is visually displayed. The resolution plane of an articulated chain is manipulated by manipulating the icon and re-determining the resolution plane using the root-effector vector and a root-control vector extending from the root to the icon. The animation of the articulated chain is constrained relative to the resolution plane and a solution of positions and orientations of all limbs of the articulated chain in achieving a goal is computed and displayed.

Abstract: The present invention is directed to a method and apparatus for startup of extruded film tubes. A controller member is utilized to provide control signals to a supply blower which supplies air to the extruded film tube in an amount corresponding to a supply control signal, and an exhaust blower which exhausts air from the extruded film tube in an amount corresponding to an exhaust control signal. The controller member executes program instructions which define at least one control routine for automatic and coordinated control of the supply blower and the exhaust blower during starting of the extruded film tube, by directing a series of supply control signals to the supply blower and exhaust control signals to the exhaust blower. When a valve is utilized to control the flow of air from the supply blower to the extruded film tube, the controller is also utilized to adjust the supply blower and the exhaust blower in order to optimize operation of the valve by placing the valve in a substantially linear operating range. Additionally, the controller member may be utilized to execute program instructions in order to implement a bubble break detection routine which utilizes software timers in combination with monitoring of a position signal in order to determine collapse or break of the extruded film tube.

Abstract: A bleed valve is in fluid communication with the compressor fluid flow path and the bypass fluid flow path whereby a piston extends radially of the valve and includes a piston head radially remote from the compressor fluid flow path. A pneumatic chamber surrounds a portion of the piston head, and air from a source downstream of the impeller is introduced into the chamber. The piston including a valuing member and a rigid sleeve connecting the piston head to the valuing means opens or closes the communication between the compressor flow path and the bypass flow path. A precompressed spring is associated with the piston to normally urge the piston radially outwardly relative to the compressor fluid flow path to a valve open position, and when the pneumatic pressure in the chamber surrounding the piston head overcomes the precompressed spring, the valve is closed.
