Abstract: A material reducing apparatus includes a reducing head that includes a rotary reducing component that carries a plurality of cutters. The reducing head includes a thrown object deflector positioned proximate the rotary reducing component. The thrown object deflector is configured to limit at least one of a distance and a direction that objects can be thrown by the rotary reducing component.

Abstract: A sorbent material is disclosed for the one-step separation of bio-macromolecules in a single pass extraction of DNA from complex mixtures of molecules and chemicals. In one embodiment, the sorbent material comprises a silanized material at least partially coated or formed with a polymer selected from the group consisting of a poly(aryl methacrylate), a poly(aryl acrylate), a poly(heteroaryl methacrylate, a poly(heteroaryl acrylate) and a copolymer thereof.

Abstract: Fabrication of a microfluidic multi-temperature reaction device (MMR) and the design and fabrication of the equipment to drive various molecular biological methods on the device are provided. The device can be applicable, for example, to nucleic acid (DNA, RNA, cDNA, etc) amplification, cell lysis, reverse transcription and other enzymatic temperature sensitive and also temperature cycling reactions.

Abstract: Various embodiments of the present disclosure generally relate to molecular biological protocols, equipment and reagents for the extraction and fractionation of DNA molecules, from whole or lysed samples, in a single flow-through device.

Abstract: The present invention provides a leveling control system for a forestry machine (10) employing position sensors that relay information about the orientation of the carriage (12) in relation to the swing-house assembly (14) in order to control roll and pitch in a manner that maximizes the operating envelop of the leveling mechanism (38). The angles of pitch and roll of the swing-house assembly (14) in relation to the carriage (12) are measured and/or calculated and a controller (24) limits operation of the leveling mechanism (38) to an operating envelop that may be described in terms of pitch and droll. The cylinders (54, 56) are decelerated gradually as the operating envelop is approached. The controller (24) can include an automatic leveling mode. The controller (24) can change the function of the fore, aft, left and right operator controls so that they are true from the operator's frame of reference regardless of the rotary position of the cab relative to the carriage (12).

Abstract: An infeed chute that is configured to more effectively and safely guide brush into a chipper is provided. The infeed chute is configured to guide brush upwards, thereby minimizing the occurrence of branches inadvertently catching the bottom edge of the chute. The infeed chute is also configured so that operators can conveniently load the chipper while being along a side of the chipper.

Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.

Abstract: A foldable toothbrush having a self-contained storage compartment contiguous with the body of the toothbrush. A pair of storage compartments are connected to one another, one of which is, in turn, connected to an arm assembly. The arm assembly has a pair of members connected to each other. The toothbrush's bristles are attached to the outermost member of the arm assembly. In its fully folded position, the arm assembly's members fold down on one another to form a folded arm section which is folded into one of the storage compartments. The other storage compartment folds down onto the first storage compartment to yield a small, flat, cylindrical case which houses the toothbrush which can easily be stored in a purse or pocket. The foldable toothbrush is designed to be inexpensive enough to be disposable but sturdy enough to withstand repeated use.

Abstract: A toothbrush with a bristle head that has densely packed hexagonal tuft holes and hexagonal cross section bristles exhibits increased bristle retention. The increased bristle retention is achieved by increasing the anchored length of the tuft staple without increasing the overall length of the staple. Where the hexagonal tuft holes are of the same area as conventional round tuft holes, and the anchoring staples are of the conventional length, the "anchored" length of the staple is increased by 25%. Bristle retention is further increased by the increased friction of the flat surfaces of hexagonal bristles against each other and against the flat surfaces of hexagonal tuft holes.

Abstract: An improved toothbrush is provided with a flexible neck to avoid damage to teeth and gums due to excessive brushing pressure. The toothbrush has a bush head made of a semi-rigid material to adequately support bristles, and a handle and neck made of an elastic material. The elastic material of the handle is comfortable in the users hands. The elastic material of the neck provides the flexibility to avoid damage due to excessive brushing pressure exerted by the user on the handle. The flexible neck is reinforced by semi-rigid arms formed integral with and ending from the semi-rigid material of the brush head. The reinforcing arms are connected by a web with spaced-apart openings. The web openings are provided to receive a portion of the elastic material of the neck to further secure the neck and the handle to the brush head.
