Patent CA-2237012-A1 (CA)
Title: Independent brake handle assembly
Inventor: SANTORO RALPH JR
IPC: G05G9/047
Filed: 1998-05-06
Abstract: A handle assembly of the type used in railway locomotives has been improved. The handle assembly includes a base plate, a cam mount attached to the base plate, a cam disk, and a shaft assembly interconnecting the mount and disk to allow rotation of the disk. The improvement includes a yoke, a bail bar, first and second bearing members anchored to the plate, and first and second switches attached to the plate. Pivotally connected to the disk and accommodating a handle, the yoke rotates along with the disk as the handle is moved along its range of motion and tilts as the handle is moved perpendicularly thereto. The bail bar is rotatable between the first and second bearing members. A first mechanism imparts a rotational force to the bail bar so that its middle section presses against an upper portion of the yoke. A stop limits rotation of the bail bar to a point at which the yoke and handle attain an untilted state. Operating against a lower portion of the yoke, a second mechanism provides a counterbalancing force to normally bias the yoke in the untilted state. No matter where the handle is positioned along its range of motion, when it is tilted by a preset amount, the yoke overcomes the rotational and counterbalancing forces so that a third mechanism causes both the first and second switches to change state.

Title: Chroma keying studio system
Inventor: TZIDON AVIV
IPC: H04N5/272
Filed: 1997-01-29
Abstract: A video system is described which creates a virtual shadow of a foreground object filmed in front of a blue screen with a main video camera. The virtual shadow is created using a second video camera located as a virtual light source. Images from both cameras are processed by a chroma keyer to separate the foreground object. The video image from the second camera is processed to create the virtual shadow and both video images are combined with background image. Object location and actor prompting systems are described to enable an actor to easily find his way around the set, and to focus his gaze on the virtual objects appearing in or disappearing from the studio. The prompting system gives the actor the timings for various events taking place in the studio. The special markings are completely invisible to the camera and to the home viewers because they are either projected in a chroma-key color, or are only active during virtual blanks of the camera such as the vertical blanking interval or the horizontal blanking interval in an NTSC, PAL, SECAM or other video signal format.

Patent CA-2245368-A1 (CA)
Inventor: HENNIG GREG E
IPC: E21B29/06
Filed: 1998-08-19
Abstract: An assembly, mountable below a whipstock, for engagement into an anchor packer is disclosed which has a valve member as a principal component. The assembly is stabbed into the anchor packer in a manner that isolates the main wellbore from the lateral to be created using the whipstock. An equalization feature facilitates the stabbing in of the assembly into the anchor packer. Upon concluding the stabbing in, the equalization opening closes and locks in the closed position. Thereafter, the lateral is created by milling a window (in the case of a cased wellbore) and drilling the lateral. Liners may be used within the lateral and are insertable by use of the whipstock. At any desired time when production is to resume from below the whipstock, the valve member is actuated while the anchor packer remains in position to hold the whipstock. The valve member can be actuated by mechanicallyshifting a sleeve or by dissolution with chemical attack of a dissolvable plug or by other techniques. The opening of the valve member can also be accomplished by a signal from the surface which travels through the wellbore, such as an acoustic signal, which is received downhole which ultimately actuates the valve member to the open position. Provisions can also be made to subsequently close the valve should it become necessary to isolate the main wellbore below the whipstock at a future time. This can be accomplished with the use of previously mentioned methods or the use of battery-powered activated memory metal technology.
