Title: Parking brake system
Inventor: GURLEY ANTHONY G
IPC: F16D65/28
Filed: 1998-10-07
Abstract: A parking brake system for applying the brakes 64 of a vehicle includes a hydraulic portion and a mechanical lock portion. The hydraulic portion includes a cylinder 70 for receiving fluid under pressure, and a rod 72 which is movable within the cylinder 70 by the pressurized fluid. The rod 72 is in mechanical communication with the brakes 64 of the vehicle, and the rod 72 may be moved in a first direction for applying the brakes 64 and in a second direction for releasing the brakes 64. The hydraulic portion also includes a control valve 106 that may be activated for preventing fluid from exiting the cylinder 70, whereby when the control valve 106 is activated, the rod 72 is prevented from moving to release the brakes 64. The mechanical lock portion may be activated independently of the hydraulic portion, and allows the rod 72 to be moved in the first direction for applying the brakes 64, but prevents the rod 72 from being moved in the second direction to release the brakes 64. The mechanical lock portion and the hydraulic portion act as backups to eachother so that if one of the portions fails, the other portion will still hold the brakes 64 in the applied position.

Title: Improved electroplating method and apparatus
Inventor: ZHANG MING JASON
IPC: C25D5/06
Filed: 1998-10-07
Abstract: The present invention provides an improved method for electroplating metallic ions onto a conductive substrate. In one embodiment, the method comprises at least partially covering a selected surface of the conductive substrate with an electrode wrap that includes a pad having an abrasive surface. The metallic ions are electrically depositing onto the selected surface through the electrode wrap while the conductive substrate is moved (e.g., rotated) relative to the electrode wrap. A substantially constant frictional force is controllably applied from the abrasive surface onto the selected surface while the metallic ions are being deposited. In this manner, a substantially constant abrasive force is applied to the selected surface as the thickness of the deposited metallic coating increases to create a relatively smooth, uniform, thick deposition that is substantially free of defects.

Abstract: A self-verifying temperature sensor and method for measuring and verifying the true thermodynamic temperature of a system. The sensor is constructed of various combinations of the following temperature-dependent elements:  thermoelements, resistive elements, capacitive elements and other inductive elements. In the preferred embodiment, the sensor is constructed of resistive element connected between four thermoelement wires. A fifth thermoelement wire is connected to the resistive element. The sensor produces a data signature from various voltage, resistance, inductance, and capacitance measurements.  Measurement electronics collect and condition the data signature. A computer analyzes the data signature and provides the system operator with a verified sensor temperature, thus, allowing the system operator to recognize and account for drift or decalibration of the sensor. The self-verifying temperature sensor can also be recalibrated in situ, thereby eliminating the necessity of sensor removal to verify recalibration.

Abstract: The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating a cationic amidoamine into the fiber furnish at the wet end of the tissue machine prior to formation and/or by topical addition to the tissue web. One or more softeners/debonders can be added to the furnish and/or topically applied to the tissue web after the tissue web is dried. The result is a tissue product with added bulk and a smooth surface feel, both properties contributing to improved softness characteristics.

Abstract: The phase modulator in the laser resonator requires both at the input and at the output defined linearly polarized light which has to be generated.  Hitherto, this was brought about in a complex and expensive manner using polarization actuators. The invention provides a combination of dispersion compensation and definition of the linear polarization state in a dispersion compensation fibre (PM-DC fibre) which is birefringent at such a high level that only the two orthogonal linear polarization states can be diffused therein. The invention can be used for mode-locked fibre lasers in which the time pulse width has to be as small as possible.

Title: Objective lens having constant focal length in visible and ir range
Inventor: NOYES GARY R
IPC: G02B9/16
Filed: 1998-09-02
Abstract: The focal length of an objective lens system is substantially equal at two wavelengths: one within the visible spectrum and one within an eyesafe IR spectrum centered about 1.54µm; the lens is essentially achromatic throughout the entire visible spectrum (0.45µm-0.70µm) and is well-corrected for other monochromatic aberrations (spherical aberration, coma, astigmatism, field curvature, and distortion). By having an objective lens (12) that is common to both optical paths (visual 36, 42 and laser 36, 44) and has the property of having essentially the same focal length and essentially the same angular deviation for the two optical paths upon lens decentration, then a practical mechanism can be included in the opto-mechanical design of a laser rangefinder to adjust the x and y decentration of the objective lens to accomplish a corresponding x and y adjustment of the system boresight. One specific embodiment is a cemented triplet (14, 16, 18; 14', 16', 18') in which the front lens element (l4, 14') is bi-convex and is formed of a crown glass having a relatively high index of refraction (n) and a moderately high inverse relative dispersion (V); the rear element (18, 18') is substantially piano convex and is formed of a crown glass having a relatively low index of refraction and a relatively high inverse relative dispersion; and the middle lens element (16, 16') is bi-concave and is formed of an anomalous dispersion flint glass having an index of refraction intermediate that of the front and rear elements and an inverse relative dispersion that is substantially below that of those other two elements, with partial relative dispersion being displaced from the "normal" line by at least twice and preferably at least six times the distance associated with the normal glasses forming the two convergent elements (14, 18; 14', 18').

Abstract: This invention is a method for incorporating concurrent delivery of a bactericidal agent into water intended for supply to a dental unit. A  reservoir (23) adapted to contain a liquid bactericidal agent is connected to a variable rate pump (22) having an inlet line (24) extending from the reservoir to the inlet of the pump. An outlet line (26) extends from the pump outlet and provides a bactericide supply line. A water supply line (10) is adapted to be connected to a source of water under pressure which provides a flow path through the system to a suitable outlet adapted to be connected to a dental unit. A mixing junction (20) interconnects the water supply line and the bactericide supply line so that bactericide can be mixed into the water supply line. A flow sensing unit (28) is responsive to fluid flow in the water supply line, and generates an output parameter representative of this flow rate. A flow control system (29) responds to this measured parameter to vary the pumping rate of the pump. An elarged mixing chamber (34) is located between a mixing junction and the water supply line outlet with the sensing unit interposed between the mixing chamber and the mixing junction. A water filter (12) is interposed between the water supply line between the inlet thereof and the mixing junction. Check valves (18, 30) are located in the water supply line upstream/downstream of the mixing junction. The mixing chamber is interposed between the second check valve and the outlet of the supply line.
