Title: High load-carrying turbo oils containing amine phosphate and 2-alkylthio-1,3,4-thiadiazole-5-alkanoic acid
Inventor: KIM JEENOK T
IPC: C10M169/04
Filed: 1996-12-06
Abstract: This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives. The S-containing additive of the present invention is 2-alkylthio-1,3,4-thiadiazole-5 alkanoic acid (ATAA) obtained by reacting 2,5-dimercapto-1,3,4 thiadiazole (DMTD) with alkyl bromide and subsequently reacting the intermediate with haloalkanoic acid. The P-containing additive is one or more amine phosphate(s). The turbo oil composition consisting of the dual P/S additives of the present invention achieves a superior load-carrying capacity over that obtained when each additive was used alone at individual treat rates higherthan the total additive combination treatrate, and also meets or exceeds US NavyMIL-L-23699 requirements including Oxidation and Corrosion Stability and Si seal compatibility.

Abstract: A squeeze and turn child resistant package including a container having a finish (46) and a closure having a base wall (26) and an outer peripheral flexible wall (28) depending from the base wall. The wall has an internal thread on the inner surface thereof, the finish has an external thread thereon. The closure has an internal surface with spaced flexible chordal lugs (70) extending circumferentially in the direction of removal of the closure. The container finish has opposed radially extending abutments (52). Each abutment includes a radial abutting surface (54). The finish of the container includes an integral radial projection (56) adjacent the radial abutting surface of the abutment which has a lesser radial extent than the abutment. The radial projection has a chordal surface extending to the intersection of the radial abutting surface on he finish such that the chordal lug (70) on the closure is forced toward the intersection when a closure is rotated in a retrograde direction to remove the closure without flexing the peripheral wall. The finish has stops (50) below the threads engaging a blunt end leading end (51) of the thread on the closure to limit the movement of the closure and orient the closure. <IMAGE>

Patent CA-2204324-A1 (CA)
Inventor: HART JAMES E
IPC: B60T13/66
Filed: 1997-05-02
Abstract: A regulating valve device is provided for utilization with an end-of-train unit in order to reduce a train brake pipe pressure from the rear end in accordance with a pressure reduction initiated at the locomotive on the front end.  A stepping motor under control of a microprocessor controls the compression of a spring to establish a target pressure corresponding to a pressure command signal transmitted from the locomotive to the end-of-train unit.  The service exhaust valve device regulates the brake pipe pressure to the target pressure corresponding to the spring compression set by the stepping motor and includes  an arrangement for overriding the motor control in the event of a fault condition that prevents the motor from resetting the spring to its initial compression when it is desired to recharge the brake pipe to release a brake application.

Title: Method and device for error control in video compression
Inventor: LEVINE STEPHEN N
IPC: H04N7/50
Filed: 1996-08-27
Abstract: The present invention provides a method (200) and device (300) for error control of a video compressed sequence in which error protection for both random and burst channel errors is provided. The error control syntax (100) applies a fixed length packet synchronization system to variable length coded compressed video data, which provides the capability to limit error propagation within the decoded video bit stream. The fixed length packet control information provides information to decode compressed video data in both forward and reverse directions to allow for the recovery of correctly decoded video data within a decoded frame after long bursts of channel errors while reducing the overhead for error control. The error control method also provides video error detection which may be used for error concealment.

Title: Method and apparatus for detecting eye location in an image
Inventor: SWAIN CASSANDRA TURNER
IPC: G06T7/00
Filed: 1998-04-27
Abstract: Method And Apparatus For Detecting Eye Location In An Image A simple method for segmenting eyes and extracting parameters enables further processing of the image to enable a person to appear to be making eye contact with another via a video conferencing system. This method is a first step for eye synthesis and gaze detection because it can automatically extract select eye parameters useful to these processes. Its advantage is that no a priori information is necessary to segment eyes, unlike modeling and neural network methods. The method of the present invention first blurs the image to make it easier to determine the location of the two eye regions in the image. The eyebrows are then eliminated based on the located eye regions. The eyes are thensegmented and the eye parameters are extracted from the resulting image. According to the present invention, the process applies a Gaussian filter, h(~,.gamma.),where g(~,.gamma.) is the resulting image and(~,.gamma.) is the original image.

Title: Container sealing surface area inspection
Inventor: SHEPHERD WILLIAM T
IPC: G01N21/00
Filed: 1998-05-08
Abstract: Apparatus for inspecting the sealing surface area of a container finish that includes a structured light source positioned to direct a collimated line-shaped light beam onto the sealing surface area of a container as the container is moved relative to the light source. The line-shaped light beam at the container sealing surface area has a long dimension orthogonal to the container axis that extends chordally across the sealing surface area, and a narrow dimension tangential to the container axis. A light sensor is disposed to receive portions of the line-shaped light beam reflected from the sealing surface area, and provides an electrical output signal that varies with height or level of the sealing surface with respect to the light source and sensor. The sensor is coupled to associated electronics for providing information indicative of sealing surface height. The elongated dimension of the line-shaped light beam at the container sealing surface area accommodates wobble or misalignment at the sealing surface with respect to the light source and sensor. Furthermore, the elongated radial dimension of the line-shaped light beam at the container sealing surface area produces a reflection on the sensor from any wire-edge or over-press within the container mouth, thus producing at the sensor information indicative of both existence and height of any such wire-edge or over-press.
