Abstract: Various traveling wave grids and electrophoretic systems, and electrode assemblies using such grids, are disclosed. A configuration in which a voltage potential is used to load a biomolecule sample against a grid is disclosed. A unique strategy of using multiple, reconfigurable grids in such systems is also described. The strategy involves initially conducting a broad protein separation and then selectively tailoring one or more grids, and conducting one or more secondary processing operations. Related strategies and specific methods are additionally disclosed for separating samples of biomolecules and components thereof using the noted systems, assemblies, and grids.

Abstract: A splice connector includes a first IDC terminal, a second IDC terminal, a body receiving the first and second IDC terminals, and a cover connected to the body such that the cover selectively slides with respect to the body in the first linear direction from first position to a second position. The body defines a first seat configured to receive an associated first cable and second seat configured to receive an associated second cable that is to be electrically connected to the associated first cable. The first and second IDC terminals each include a portion that extends into a region adjacent a respective wire seat. The cover is configured to cooperate with the body where a portion of the cover engages a portion of the body at a third position between the first position and the second position such that in the third position movement of the cover with respect to the body in a second direction, which is opposite the first, is inhibited.

Abstract: The coating device (10) for coating a metal band or strip (12, 12?) in a melted metal mass (14 ) comprises a shaft (16, 18) rotatably supported in the melted metal mass (14) by a slide bearing (261, 262) is formed by a bearing housing (32) and an open bearing shell (34) held therein, with two bearing surfaces (36) . Between the two bearing surfaces (36), the bearing shell (34) comprises a deformation zone (40) with a deformation element (44) . With high radial forces of the shaft occurring, the two bearing shell halves (381, 382) are slightly spread. The flexible deformation zone ensures that the two bearing shell halves remain interconnected and resist breaking in this area.

Abstract: A nuclear camera (10) includes a plurality of detector heads (12) which have collimators (14) for fixing the trajectory along which radiation is receivable. A rotating gantry (22) rotates the detector heads around the subject collecting less than 360° of data, e.g., 204° of data. A zero-filling processor (50) generates zero-filled projection views such that the actually collected projection views and the zero-filled projection views span 360°. A smoothing processor (56) smooths an interface between the zero-filled and actually collected projection views. The zero-filled and smoothed views are Fourier transformed (60) into frequency space, filtered with a stationary deconvolution function (62), and Fourier transformed (64) back into real space. The resolution recovered projection data sets in real space are reconstructed by a reconstruction processor (68) into a three-dimensional image representation for storage in an image memory (70).

Abstract: Apparatus for conducting geophysical surveys comprising a multiplicity of intelligent electrodes provided on a multi-conductor cable, for receiving a command signal in response to which predetermined electrodes are connected to selected conductors in the cable. Each intelligent electrode is identical in all respects, including its programming, resulting in simplified construction of the cable and easy replacement of the intelligent electrodes. Instead of assigning a unique address code to each switch in a series of take-outs on a multi-conductor cable, each electronic switch is programmed with the same address code. That is, each switch is programmed to be activated when it receives a code command that, for example, is prefaced with a particular address, e.g. the number 1. The second part of the code (y) instructs the switch as to which conductor in the multi-conductor cable is to be connected to the local electrode at the location of the switch.

Abstract: A vaporizer (14) supplies hydrogen peroxide and water vapor to a high level disinfection or sterilization region (20). Mid-infrared light detectors (32) detect light in the mid-infrared range which has traversed a region of the treatment chamber in a first narrow spectrum centered at 8,000 nanometers which is absorbed by the hydrogen peroxide vapor, a second narrow spectrum which is absorbed by the water vapor, and a third spectrum that is absorbed by neither the hydrogen peroxide vapor nor the water vapor. From these measurements, an absorbance or transmittance is determined (40) from which the concentrations of hydrogen peroxide and water vapor are determined (42). Monitored temperature (44) and the determined concentrations are converted into a percent saturation (54). The supply of hydrogen peroxide and water vapor to the chamber is controlled (60) in accordance with the determined percent saturation.

Abstract: A multi-chamber installation (1) treats objects under vacuum. An evacuation system (5) is connected to a plurality of chambers (2, 3, 4). To reduce the complexity of the evacuation process, a forepump (5) has several stages (11, 12, 13). Each of said stages is connected to one of the chambers (2, 3, 4).

Abstract: A vehicle (1) includes a chassis (2) which has a steering assembly (3) at one end and at least one wheel at the other end. The steering assembly includes a pair of steering wheels (4a, 4b) and an interconnecting steering carriage (4) for turning the wheels about a steering or turning axis (ZZ?). An extensible cylinder (6) is connected between the chassis and the steering linkage for rotating it about a transverse axis (YY?) which, in turn, inclines the steering axis (ZZ?). Preferably, the extensible cylinder is controlled in accordance with the speed of the vehicle.

Abstract: A vacuum pump (10) comprises at least one rotor shaft (12) having a rotor section (14) with a rotor (16), a bearing section (18) with a bearing (20), and a shaft sealing system (22) that is axially situated between the rotor section (14) and the bearing section (18). The shaft sealing system (22) axially comprises, on the side of the rotor, a gas seal (32) and, on the side of the bearing, an oil seal (34). The shaft sealing system (22) additionally comprises, between the gas seal (32) and the oil seal (34), a separating chamber, which surrounds the rotor shaft (12) and is ventilated by at least one separating chamber ventilation duct (60, 62). This enables the pressure difference that decreases via the gas seal and the pressure difference that decreases via the oil seal to be adjusted. An appropriate adjustment can prevent oil on the bearing side from passing through the oil seal toward the separating chamber.

Abstract: A vacuum cleaning system for a vehicle includes a console (12), which may be centrally positioned between the front seats (16) of the vehicle. A canister (10), in the form of a drawer to the console, is selectively removed, when vacuuming is to be commenced, and a flexible hose (96) unclamped from a side compartment (112) of the canister. The canister, with the hose attached, is carried by a handle strap (58) to a part of the car to be cleaned. A motor fan assembly (70) within the canister is powered from the vehicle's battery by means of a power cord (84) to draw dirt into a dirt cup (90) in the canister. Entrained air passes from the dirt cup through a filter (94) and is directed by the fan to an exhaust outlet (82) in the canister.

Abstract: A grill cover device includes a flexible cover defining a hollow recess having an open mouth. The recess is adapted to receive an associated grill therein when the flexible cover is in an expanded condition. A flexible resilient frame is connected to the flexible cover. The frame exerts a biasing force on said flexible cover to bias the cover into its expanded condition. The frame and the flexible cover are selectively resiliently deformable as a unit against the biasing force of the frame into a collapsed storage configuration in which the frame and cover are folded upon themselves.

The panels can also define half I-beam post/cross-members so that adjacent abutted panels cooperate to define additional full I-beam post/cross-members.
