Abstract: Apparatus for processing a liquid comprising a target substance, preferably a biomolecule, is provided.

Abstract: A column assembly for use in conjunction with a test machine, for inducing high-cycle fatigue (at kilohertz vibration rates) in a specimen of a material under test. The column assembly has isolation masses, a specimen grip, and two actuators, the latter for imparting dynamic forces to the test specimen. The actuators are arranged on the column assembly asymmetrically relative to the test specimen.

Abstract: A test machine (10, 40, 60) for inducing high-cycle fatigue (at kilohertz vibration rates) in a specimen of a material under test. Each test machine (10, 40, 60) provides both dynamic and static loading. One embodiment is an SEM-compatible machine (10), having an inner frame (11) containing symmetrical components on either side of a stationary node. The specimen is placed at this stationary vibration node. Dynamic loading is the result of vibrations provided by two piezoelectric actuators (16) inside the frame (11), one on each side of the node. Static loading is provided by means of two stress rods (12), each extending from an end plate (11a) into the frame (11). A pair of cylindrical couplers (14) is also inside the frame, one coupler (14) on each side of the node. Each coupler (14) is attached to an associated piezoelectric actuator (16) and stress rod (12) such that the static and dynamic loads are transferred to the couplers (14).

Abstract: A brake system control for use in a vehicle that calculates a wheel slip for at least one wheel, wherein the brake system control comprises the steps of: monitoring the calculated wheel slip; imposing a discriminating criteria on the monitored wheel slip wherein the discriminating criteria determines whether or not the calculated wheel slip accurately reflects an actual operating condition of the wheel; implementing ABS control using an adjusted wheel slip for the wheel when the discriminating condition determines that the calculated wheel slip does not accurately reflect an actual operating condition of the wheel; and implementing ABS control utilizing the calculated wheel slip when the discriminating condition determines that the calculated wheel slip accurately reflects an actual operating condition of the wheel.

Abstract: This invention relates to a road barrier, particularly to a road barrier for separating traffic lanes on a bridge. In the preferred embodiment, the barrier is made up of beams formed from steel three-beam guardrail sections. Steel tubes or flanges are welded to the top and bottom of the guardrail sections and a transverses stiffener is welded to one side. The barrier's sections are removable mounted by pins in anchors attached to the bridge deck.

Abstract: Longitudinally extended printing of all types of computer output for reading in the direction in which the paper was caused to flow during printing is provided for instead of the conventional printing for reading across such direction. Existing hardware is utilized, with the imprinting characters having their reading axes disposed transversely to the axis of paper flow. Imprinting of the advancing print-out form is by means of a succession of transverse rows of the transversely orientated characters, and in each imprinted row there is added a respective character to each of a plurality of longitudinally extended lines of data to be read at completion of the print out in the direction of paper advance during printing and across the rows of imprinted characters.

Abstract: A hydraulically actuated collet type grip with an elastic support structure to allow for the axial bending needed to compensate for diametral dimension changes in the specimen gage section to be accomodated within the grip rather than within the tubular specimen. The tabbed end of the tubular specimen is gripped in the annular region of the loud transfer section of the collet. Load transfer is achieved by normal pressure on the collet and the frictional interface between the collet and the bonded end tabs on the specimen.
