| 6966443 | Paraffin filter element A paraffin filter for a paraffin spa includes a first end cap and a second end cap with a filter medium sandwiched therebetween. Each end cap is disk-like body having a respective tubular connection for the input or output of melted paraffin, thus providing a low pr... | 11/22/2005 |
| 6901271 | Determining the last digit of a dialed number A technique for determining the last digit of a dialed sequence. Different interdigit time-out periods are pre-assigned to each digit received. If the time-out period expires, it is considered that a full complement of digits has been received, whereupon the receive... | 05/31/2005 |
| 6781161 | Non-gated thyristor device A semiconductor device with two epitaxial layers formed on a substrate. The middle layer of epitaxial material can be formed thin and with an appropriate doping concentration to provide a low avalanche breakdown voltage with a negative resistance characteristic. The... | 08/24/2004 |
| 6739797 | Interlocking erosion control block with integral mold A block (11) formed with a mold (10) integral thereto. The mold (10) is constructed as a mold top half (12) and a mold bottom half (14) and filled in situ with cement (16). The mold halves (12,14) are constructed with... | 05/25/2004 |
| 6696709 | Low voltage protection module A semiconductor thyristor device incorporates buried regions to achieve low breakover voltage devices, and the buried regions are offset laterally with respect to the emitter regions. The low voltage thyristor devices can be incorporated into five-pin pro... | 02/24/2004 |
| 6671959 | Tool for extracting a bearing A tool for extracting a bearing race from a bearing support structure. The tool is sufficiently narrow for sideways insertion into the bearing race. The tool can then be rotated within the race so that the tool engages with an annular flange of the bearin... | 01/06/2004 |
| 6640715 | Wearing apparel with scented ink 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 s... | 11/04/2003 |
| 6631886 | Winch housing with integral fairlead A winch constructed with a fairlead frame providing a mounting base for the winch and providing a rotational support for a cable drum. Loads exerted on a cable and through the fairlead rollers and cable drum are transferred to the unitary fairlead frame m... | 10/14/2003 |
| 6627072 | Filter system for a paraffin spa 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) th... | 09/30/2003 |
| 6588983 | Trenchless pipe replacement apparatus and technique 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 ... | 07/08/2003 |
| 6531717 | Very low voltage actuated thyristor with centrally-located offset buried region 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 cu... | 03/11/2003 |
| 6508607 | Erosion control block adapted for use with cellular concrete mattresses 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 i... | 01/21/2003 |
| 6505281 | Hard disk drives employing high speed distribution bus 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 ... | 01/07/2003 |
| 6448589 | Single side contacts for a semiconductor device A connector block formed in a semiconductor chip to provide all contacts on the same side of the chip.
