Patent CA-2541793-C (CA)
Inventor: HAUPT DIETER
IPC: H04N5/91
Filed: 2006-04-05
Granted: 2013-12-31
Abstract: Various applications record or handle uncompressed video, where the amount of information needed for each frame or field is constant, based on the video frame rate and colour resolution of each pixel. Since various video frame rates and audio sample rates are defined and can be combined independently, the amount of audio samples per video frame may vary. The disclosed method allows packing audio samples and video samples into constant size containers, e.g. MXF containers, so that there is an integer amount of audio samples within the time period needed for one video frame, independent from the used video raster. The method includes generating constant length KLV encoded video packets (PicI), generating variable length KLV encoded audio packets (AudI) corresponding to the same time period as the video packets (PicI), generating variable length KLV encoded data packets (DatI), wherein the sum of the lengths of the audio packet and the data packet are constant, and generating from said packets a constant size content package (CP_1,...,CP_N).

Abstract: A method for determining the thickness of a dryable or curable film-forming coating by incorporating a fluorescent component into the coating. The fluorescent component is either a resin solid of the coating, a fluorescent dye or a fluorescent dye attached to a resin solid of the coating. The coating is exposed to ultraviolet or visible light which causes the fluorescent component to fluoresce. The intensity of the fluoresce of the coating is measured and the thickness or weight of the coating is determined from a known mathematical relationship between the fluorescence intensity of the coating when exposed to the light and the thickness or weight of the coating. Additionally, a curable or dryable film-forming coating composition including a curable or dryable organic resin reacted with a fluorescent tag is provided.

Granted: 2014-09-09
Abstract: According to the invention, a drill rod comprising an inner channel is drilled into the rock. A free-flowing, self-hardening mass is pressed through the inner channel of the drill rod, filling the drilled hole, so that it hardens with the drill rod remaining in the drilled hole. The hardening mass is a mixture of a hardenable plastic and a hardening plastic. Said plastics are supplied to the inner channel of the drill rod over a pre-determined transport time F which corresponds to the hardening time. The hardening time is defined by the selection of the plastics and the mixing ratio thereof such that the transport time essentially corresponds to the hardening time and leads essentially to the flow path of the hardened mixture being completely filled between the mixing point and the output of the drilled hole.

Title: Earth boring bit
Inventor: ENGSTROM ROBERT W
IPC: E21B10/42
Filed: 2007-10-11
Granted: 2011-04-05
Abstract: The earth boring bit 10 is designed to bore an angular non- vertical hole into underlying strata. The bit 10 includes a plurality of steeply inclined cutting faces or edges 22 that define a relatively narrow included angle A  therebetween. The bit's design ensures that the apex of the bit 10 will contact the surface S and/or other hard strata before the radially outwardly disposed gauge portion of the bit 10. This design reduces or obviates drill chattering or "walking" when the bit 10 is used to drill a hole at an angle that is not vertical relative to the surface or strata S. The bit 10 also includes an interchangeable flow control restrictor that optimizes the velocity of fluid pumped through the bit 10 and thus efficiently flushes debris from the hole as the hole is being drilled.
