Patent number: 6640715Abstract: A process in which a scented ink is applied to an article. An oil-based scent is mixed with a plastisol-type ink and applied to an article, such as a t-shirt. All layers of the ink forming the design, including the base layer, the color layers and a top special effects clear plastisol ink, include the scent. The combination of a plastisol ink and the oil-based scent results in a design with a positive “hand”, where elevated temperatures activate the scent.Type: GrantFiled: August 31, 2001Date of Patent: November 4, 2003Inventors: Patrick L.

Patent number: 6627072Abstract: A paraffin filter system (10) includes an in-line low-profile particulate filter (20) connected to a suction tube (14) which is used as an inlet to the paraffin filter system (10). A paraffin pump (54) pumps the melted paraffin from a paraffin spa (12) through the particulate filter (20) to a transfer container (11) via a discharge tube (22). A heater (78) is controlled by control logic (146) to operate in certain modes to melt any residual paraffin in the filter (20) and pump (54) before operation of the pump (54). The control logic (146) provides various modes of operation of the filter system (10) to assure that the system is ready to operate, irrespective of the operation of a control panel switch (6) by the user. When the paraffin is transferred back to the spa (12) from the transfer container (11), the melted paraffin is carried through a bacteria filter (21) in the filter system (10).Type: GrantFiled: March 2, 2001Date of Patent: September 30, 2003Inventor: Robert A. Ridge

Patent number: 6588983Abstract: The apparatus and technique of the invention constitutes a hydraulic jack system for pushing sections of new pipe which, in turn, pushes a sleeve-cone expander arrangement to break up the old pipe and define a straight path for the new pipe. Apparatus is employed to determine the skin friction and the penetration friction, and to dispense a lubricant to reduce such frictional forces.Type: GrantFiled: August 31, 1999Date of Patent: July 8, 2003Inventor: Albert A. Tenbusch, II
-
Patent number: 6531717Abstract: A semiconductor thyristor device that incorporates buried regions centrally located on the chip with respect to the other semiconductor regions. By centering an upper and lower buried region, larger-area contacts can be realized, thereby increasing the current capability of the device. In order to achieve low breakover voltage devices, the buried regions are offset laterally with respect to the respective emitter regions. The low voltage thyristor devices can be incorporated into five-pin protection modules for protecting customer circuits.Type: GrantFiled: February 15, 2000Date of Patent: March 11, 2003Assignee: Teccor Electronics, L.P.Inventors: Kelly C. Casey, Elmer L. Turner, Jr.

Patent number: 6508607Abstract: A block having a semicircular male lobe and a semicircular female recess on opposing sides thereof. On other opposing sides of the block, there is formed a side edge shape such that when neighboring blocks are placed together, a circuitous water channel is formed between the blocks. The block includes cable channels formed therethrough, with the cable channels opening at the side edges into cable cavities. The cable cavities facilitate access to ends of the cables when the blocks are placed side by side.Type: GrantFiled: May 21, 2001Date of Patent: January 21, 2003Inventors: Lee A. Smith, Belinda F. Smith

Patent number: 6505281Abstract: A processor coupled by a high speed, wideband data bus to a plurality of slave data processing circuits. The data bus includes an N-bit set of master registers loaded by the processor and M number of slave modules, each slave module having an N-bit slave data register. The processor can sequentially load the master data registers and transfer the data to a selected slave module in a round-robin manner. A high speed transfer of data is thereby achieved.Type: GrantFiled: July 18, 2001Date of Patent: January 7, 2003Inventor: Raymond C. Sherry

Patent number: 6448589Abstract: A connector block formed in a semiconductor chip to provide all contacts on the same side of the chip. The connector block is preferably formed by driving a slow diffusing dopant deep into the chip from both sides until the diffused dopant overlaps in the middle of the chip. The connector block is metalized with a top contact and connected to circuits. The bottom of the connector block is metallized and connected to other bottom side contacts which, in turn may be connected to circuits. This arrangement effectively allows all contacts to be available from the top side of the semiconductor chip.Type: GrantFiled: May 19, 2000Date of Patent: September 10, 2002Assignee: Teccor Electronics, L.P.Inventors: Kelly C. Casey, Elmer Lee Turner, Jr.

Patent number: 6354596Abstract: A seal cap (10) for use in sealing an end (20) of a tendon (14) anchored to an anchor plate (12). The seal cap (10) includes a receptacle (32) for holding therein a sealing agent (37). The seal cap (10) further includes a push nut (34) that grips to the tendon end (20) when forced thereon. A foam washer (35) is held in the front part of the seal cap (10). When the seal cap (10) is forced, such as by hammering, on the end (20) of the tendon (14), the sealant is displaced onto the tendon (14), and the foam washer (35) is squeezed against the anchor plate (12).

Patent number: 6292909Abstract: Apparatus for monitoring and testing a transaction system, and controlled by enterprise automation equipment. The testing apparatus is programmed with various MIB structures to provide probe points and signals to the transaction system. Responses are received by the test apparatus via check points connected to the transaction system.

Patent number: 6288364Abstract: This invention concerns weld quality measurement. In particular it concerns an apparatus and a process for measuring on-line, while the welding process is under way, the quality of the resulting weldment. The invention is applicable to spray-transfer gas-metal arc welding, short-circuiting transfer gas-metal arc welding, pulse welding, radio-frequency resistance welding and submerged arc welding. It involves the measurement of voltage or current and the generation of an artificial signal for the other. A two dimensional signal analysis then produces data for comparison with data obtained from a high quality weld.Type: GrantFiled: November 2, 1999Date of Patent: September 11, 2001Assignee: The University of SydneyInventor: Stephen Walter Simpson
