Abstract: A step drill bit includes a body with a plurality of cylindrical steps of increasing diameter from a front end toward a rear end, a flute extending from the front end toward the rear end, and cutting edges at junctions between each step and the flute. A cutting insert with a hardness greater than the hardness of the body is coupled to the front end portion and at least partially defines a cutting head portion. The cutting head portion includes a center cutting tip, a cutting edge extending radially outward from the cutting tip, a rake face extending from the cutting edge toward the rear end portion, a relief face extending from the cutting edge in a circumferential direction opposite a rotational cutting direction of the drill bit, and a chip clearing recess in communication with the flute, with the rake face facing the chip clearing recess.

Abstract: A reciprocating saw blade includes an elongated blade body extending along a blade axis and having a rear end, a front end, a cutting edge having a plurality of teeth, a non-cutting edge opposite the cutting edge; and a tang coupled to the rear end and configured to be received in a blade holder of a powered reciprocating saw. The cutting edge includes inclined and declined cutting edge portions. The inclined cutting edge portion extends away from the blade axis and toward the front end at an acute first angle and extends from a first tooth to a second tooth. The first tooth is closer to the rear end and closer to the blade axis than the second tooth. The declined cutting edge portion extends toward the blade axis and toward the front end at an acute second angle that is greater than the first angle and extends from a third tooth to the first tooth. The first tooth is closer to the front end and closer to the blade axis than the third tooth.

Abstract: A hole cutting accessory for a power-driven tool may include an arbor that provides for quick release of an annular saw blade component of the accessory, and for quick release of a pilot drill bit component of the accessory. The quick release of the annular saw blade component from the arbor may be accomplished separately from the quick release of the pilot drill bit component from the arbor.

Abstract: For use in all wheel drive vehicles with a rear electronic differential, a device containing a switch for making and breaking an electrical connection in a ground line of a differential harness. When the circuit is broken and the rear electronic differential is not powered, the rear electronic differential does not power the rear axles. A wireless remote control has buttons that when pressed send a wireless signal to a receiver connected to the switch. When the first button in the remote control is pressed, the switch breaks the connection in the ground line. When the second button in the remote control is pressed, the switch completes the connection in the ground line.

Abstract: An accessory includes an attachment portion with a central opening configured to be coupled to an oscillating power tool and defining a first axis generally parallel to a power tool axis. An intermediate portion with a first side edge and a second side edge has a proximal end portion coupled to the attachment portion and extends away from the attachment portion to a distal end portion. A working portion is coupled to and extends away from a distal end portion at an angle to the intermediate portion and at an angle to the first axis. The working end portion has a non-cutting third side edge continuous with the first side edge and a cutting fourth side edge continuous with the second side edge. The intermediate portion wraps at least partially around an obstruction located along the first axis so the working portion can cut a workpiece located behind the obstruction.

The balm mixture includes a carrier portion and an active ingredient portion which will cause tears to form in the eye of a user adjacent the application thereof, thereby alleviating a dry eye condition.

Abstract: A control system for a hybrid vehicle. The system comprises a controller configured to cause a net negative drive torque to be applied by an engine or an electric machine of the vehicle to the input shaft of a transmission in a direction opposing travel of the vehicle to effect braking, determine when a transmission gear shift is about to occur requiring a non-negative torque to be applied at the input shaft, and when the gear shift is about to occur, temporarily cause a net non-negative drive torque to be applied to the input shaft by causing the electric machine to apply a positive drive torque to the input shaft to compensate for negative torque applied by the engine, and cause brake force to be applied by a braking system to compensate for a reduction in negative drive torque applied to the input shaft, while the gear shift occurs.

Abstract: Compositions and methods for encoding and retrieving data into nucleic acid memory for storage. More specifically, data is encoded into spatial locations within a nucleic acid architecture, which allows the data to be retrieved using super resolution microscopy. The data is then interrogated for errors, the errors corrected, and the data is then decoded.

Abstract: A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially-elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.

Abstract: A system for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors comprises a single point lifter base and an accessory mounted onto a free end of a support. The support is electrically insulated and comprises one or two tiers of elongate insulators extending away from the base. The base is for mounting the support onto a distal end of a boom.

Abstract: A method and system for controlling a tourniquet establishes a set of values for a characteristic of an induced pressure pulse in the tourniquet while the tourniquet is inflated to a working pressure which is at a predetermined offset above the limb occlusion pressure. Maximum and minimum thresholds for this characteristic value are established, such that during the working phase of application of the tourniquet the induced pressure pulse is continually monitored and the value of the characteristic is compared to the thresholds. If a threshold is reached the tourniquet is inflated or deflated accordingly to restore the value of the characteristic to within the thresholds. The characteristic of the induced pressure pulse, which may be e.g. pulse height, area under pulse or pulse width at a percentage of peak height, may also be used to determine behaviour of the pressure pulse by noting a variation in the rate of change as the tourniquet is inflated past the limb occlusion pressure.
