Abstract:
A universal cross belt sorter system (1) consisting of four major components: a monorail track (26), a drive car (20), multiple cross belt cars (24) and system controls. The drive cars (20) pull multiple cross belt cars (24) along the track (26). The cross belt cars (24) are typically loaded with material, which is then discharged into outlets. An outlet may be a chute, a bin, a conveyor, a truck, etc. Sortation systems are typically used to consolidate material according to selected parameters, such as zip code, customer order, to replenish a specific store and many other identifying information. The cross belt cars (24) are loaded with material at induction areas (3). The types or methods of inducting material onto the cross belt cars (24) range from manual to semi-automatic to fully automatic.
Abstract:
A method and apparatus for fractionation of charged macro-molecules such as DNA is provided. DNA solution is loaded into a matrix including an array of obstacles. An alternating electric field having two different fields at different orientations is applied. The alternating electric field is asymmetric in that one field is stronger in duration or intensity than the other field, or is otherwise asymmetric. The DNA molecules are thereby fractionated according to site and are driven to a far side of the matrix where the fractionated DNA is recovered. The fractionating electric field can be used to load and recover the DNA to operate the process continuously.
Abstract:
An apparatus for doctoring a cylindrical rotating surface, comprising a doctor back mounted for rotation about a first axis, and a blade carrier assembly mounted on the doctor back for rotation about a second parallel axis. A doctor blade is removably supported by the blade carrier assembly and is loaded against the rotating surface by a force applied to rotate the doctor back about the first axis. A liquid filled flexible walled tube extends along the second axis between the doctor back and the blade carrier assembly. The blade angle is adjusted by expanding and contracting the liquid filled tube to rotate the blade carrier about the second axis.
Abstract:
Improved paint brush bristles formed of synthetic materials are hollow and tapered with a central axial hollow. The tapered hollow bristles are characterized by their consistent wall thickness, i.e., ratio of cross-sectional hollow area to cross-sectional wall area remains consistent from one end of the bristle to the other; and by their consistency in neck-down location.
Abstract:
Flying electric generator aircraft that include groupings of four rotors mounted to booms extending fore and aft of a fuselage structure wherein the rotors are placed so that when the aircraft is facing the wind, each rotor has a direct path to an undisturbed flow of air, regardless of pitch angle and during all flight maneuvers of the aircraft. The rotors are placed in counter-rotating pairs with the booms preferably angled so that the rotors in the front of the aircraft are spaced at a distance from one another that is different than a spacing of the rotors at the rear of the aircraft.
Abstract:
The disclosure relates to obstacle array devices (also known as bump array devices) for separating populations of particles by size. Improvements over previous obstacle array devices are realized by causing the fluid velocity profile across gaps between obstacles to be asymmetrical with respect to the plane that bisects the gap and is parallel to the direction of bulk fluid flow. Such asymmetry can be achieved by selecting the shape(s) of the obstacles bounding the gap such that the portions of the obstacles upstream from, downstream from, or bridging the narrowest portion of the gap are asymmetrical with respect to that plane. Improvements are also realized by using obstacles that have sharp edges bounding the gaps. Other improvements are realized by selecting obstacle shapes such that the critical particle dimensions defined by the gaps in two different fluid flow directions differ.

Abstract:
A device for detecting impurities in a noble gas includes a detection chamber and a source of pulsed ultraviolet light. The pulse of the ultraviolet light is transferred into the detection chamber and onto a photocathode, thereby emitting a cloud of free electrons into the noble gas within the detection chamber. The cloud of electrons is attracted to the opposite end of the detection chamber by a high positive voltage potential at that end and focused onto a sensing anode. If there are impurities in the noble gas, some or all of the electrons within the cloud will bond with the impurity molecules and not reach the sensing anode. Therefore, measuring a lower signal at the sensing anode indicates a higher level of impurities while sensing a higher signal indicates fewer impurities. Impurities in the range of one part per billion can be measured by this device.
Abstract:
The invention is directed to an interacting microhabitat array for microorganisms having more than one microhabitat in a substrate in which at least two microhabitats are connected in series by at least one corridor. The corridor is of sufficient size to allow the microorganism to move between microhabitats in a restricted manner. The invention is also directed to uses of the device for screening for method of modulating biofilms and identifying drug candidates.
Abstract:
The invention is a monotract conveyor which has a pivotal tray which is selectively lockable to either pivot to either side of a track which the conveyor runs on, or to stay in an upright position. The tray is mounted to an upper portion of the conveyor unit which is mounted to the main body of the unit by a male/female key member connection. This connection enables one end of the upper portion to be lifted from lower portion, while the key members lock the upper and lower portions of the other end together.
