Abstract: An elongate anchor arm is rotatably secured to the side of a boat so that the arm may be rotated down from the floating boat and locked into engagement with the water bottom. An anchoring and/or orienting effect is achieved by rotating and locking the arm such that a portion of the side of the arm is forced into and held against the water bottom. For anchoring in water deeper than the length of the anchor arm, one end of a flexible anchor line is secured to a conventional line-deployed anchor and the other line end is attached to the far end of the anchor arm. The arm is rotated to achieve the anchoring and/or orienting effect of attaching the anchor line at different points on the boat.

There is a fluid guide operatively connected to the drill bit and disposed above the end of the bit body, where the fluid guide includes at least one nozzle disposed therein that is in fluid communication with a fluid cavity disposed in the drill bit, and where the fluid guide is configured to induce distribution of fluid flow in a flow regime above the drill bit.

Abstract: An automatic luminous device whose use does not require an external manual switch, which is substituted by another internal automatic switch, which activates the device only when it is placed on a sufficiently dense metal surface, nor does it require a connecting cable to an external power source, which is replaced by a preferably rechargeable battery. It was designed as an emergency light for police vehicles, and as a back-up light and is fitted with a base or casing (1) and a translucent shade (2), which, when coupled together, form a single body. Externally, the base of the casing (1) is fitted with two or more permanent magnets (3) in order to block the said casing (1), when it is placed on a sufficiently dense metal platform (4).

Abstract: The present invention provides an oily mixture based on natural bioactive ingredients to be used to prepare an enriched food product that includes salmon oil enriched with EPA and DHA, alpha-tocopherol and supercritical rosemary extract. Optionally, this mixture can contain the microalga Dunaliella salina. The invention also provides a food product enriched with this oily mixture based on natural bioactive ingredients. This enriched food product has great benefits for human health owing to its stable contents of polyunsaturated fatty acids with a ?-3 to ?-6 ratio lower than 5, of alpha-tocopherol, phenolic diterpenes derived from supercritical rosemary extract and, optionally, carotenoids derived from the microalga Dunaliella salina. Finally, the invention also refers to a method to prepare this enriched food product.

Abstract: The invention relates to a device comprising one left electrochromic filter (3) and one right electrochromic filter (4) controlled by an electronic device (12). Said electronic device has means for controlling at least one filtering parameter, said means being actuatable by the user and programmed by a professional ophthalmologist, or a combination of the two. The aim of the invention is to provide variable filtering for the vision of a user of the device.

Abstract: A rotary rock bit includes a lubricant reservoir with a pressure compensation assembly disposed therein. The pressure compensation assembly is adapted to permit selective adjustment of the relief pressure set by the assembly through the selective adjustment of one member in the assembly with respect to another member in the assembly.

Abstract: An device including a fastener. In some embodiments, the device is an electronic device that includes a circuit board, a support structure, and a resilient conductive clip. The circuit board may include a slot extending between opposite faces. The resilient conductive clip may couple to the support structure and be removably inserted through the slot so that it is disposed at least partially about the opposite faces. The resilient conductive clip may include lower and upper grounding portions engaged against the opposite faces of the circuit board.

Abstract: A latch mechanism comprising a frame having an insertion axis therethrough. A first latch spring is disposed on the frame and is biased to an extended position. A handle is connected to the frame and is movable along the insertion axis between a first position and a second position. A first cam is disposed on the handle and moves the first latch spring to a retracted position as the handle moves toward the second position.

Abstract: A computer chassis comprising a chassis base and first and second drawers removably engaged with the chassis base. An interface board is mounted to the first drawer so as to couple to a first electrical component when the first electrical component is located in the first drawer. The second drawer has a connector mounted so as to couple to a second electrical component when the second electrical component is located in the second drawer. The connector engages the interface board so as to couple the first electrical component to the second electrical component when the first and second electrical components are located in the respective first and second drawers.

Abstract: Control lines extend vertically through lateral spaces formed between a rig floor and a pipe holding assembly supported on the rig floor. A pipe string held by an elevator extends vertically through the pipe holding assembly into the well. The pipe holding assembly is raised vertically off of the floor, about the pipe string, to allow the control lines to be clamped to the pipe string below the pipe holding assembly. The invention permits the control lines to be clamped to the pipe string without passing through the pipe handling assembly to prevent damage to the control lines when the pipe handling assembly is closed to secure the pipe string.
