Title: Extended life traveling grate side plate
Inventor: FORESMAN JAMES D
IPC: F23H11/18
Filed: 2001-03-12
Granted: 2008-03-11
Abstract: An extended life traveling grate side plate having a heat transfer opening formed in a front portion of the side plate. The side plates are attached to the lateral side surfaces of each chain in a traveling grate conveyor. The front portion of each side plate overlaps the back portion of the preceding side plate such that the ba ck portion of each side plate is covered and prevented from radiating heat away from the side plate. The heat transfer opening formed in the front portion of each side plate facilitates greater heat transfer from the overlapped area of the side plate. The front portion of the side plate is generally planar and does not include any gussets, thereby eliminating the heat transfer properties of the gussets and creating a more uniform thermal expansion of the side plate (147).

Title: Heat staking head with radiant heat source
Inventor: VANKLOMPENBERG ANDREW
IPC: B29C65/18
Filed: 2001-03-20
Granted: 2009-12-22
Abstract: A head (10) for use in a heat staking machine utilizes an infrared heat lamp (40) and reflectors (38, 48) to di-rect radiant energy onto a plastic stud (16) to heat and so soften it prior to the staking punch (42) impacting the stud. The lamp (40) is disposed within a parabolic primary reflector (38) which directs the lamp's output toward a secondary reflector (48). The secondary reflector is concave and has a central aperture at its vertex through which the stud (16) projects such that all of the radiant energy emitted by the lamp (40) is focused radially in-ward onto the stud. The punch (42) is slidably mounted to the primary reflector (38) for reciprocal movement along the axes of the reflectors, and is extended to impact the stud.

Patent CA-2460298-C (CA)
Inventor: KUMAR SURINDER
IPC: H03K7/10
Filed: 2004-03-09
Granted: 2008-02-12
Abstract: The present invention provides a means to implement amplitude and phase modulation digitally and directly at an RF frequency that benefits from high output power without the use of amplifiers. This is accomplished by the combination of two varying amplitude and phase vectors. A reference oscillator produces a carrier signal, which is supplied to two digital delay lines composed of a sequence of delay banks. The delay lines are controlled by lookup tables that are updated by the vector control circuit, used to determine the delay of each digital delay line. The output of each delay line is multiplexed to a switching bank which is also controlled by the vector control circuit. The output of the switching bank, in combination with a summer, is used to produce discrete amplitude adjustment of the vector. The delay of the lines and the summation adjustment are set in such a way as to produce two vectors with the desired phase shift and magnitude the summation of these two vectors produces a resultant vector with the desired phase and amplitude characteristics.

Granted: 2012-12-18
Abstract: Described is a hierarchical index that captures the hierarchical relationship of a hierarchy emulated by a relational database system. The hierarchical index is implemented, using a database table which contains rows that serve as entries of the hierarchical index. Another table has rows that are associated with nodes in the hierarchy. Each entry in the hierarchal index maps to a row that corresponds to a node in the hierarchy. A node in the hierarchy may be a parent node with one or more child nodes. In this case, the corresponding entry in the hierarchical index contains identifiers which identify other entries in the index, where the other entries correspond to rows associated with child nodes of the parent node.
