Abstract: A system for accurately determining whether a work piece such as a plastic molded bottle cap is defective from quality norms and removing those defective pieces from a stream of work pieces includes a feed conveyor for serially delivering work pieces where adjacent work pieces are in contact with each other. The feed conveyor delivers these work pieces onto an inspection conveyor with a plurality of air holes. Air is forced through the air holes to impinge upon the work piece and thus rapidly accelerate them away from the adjacent work piece it was in contact with and move through an inspection station. An air blower provides pressurized air through the air holes to continue accelerating and separating the work pieces as they move. The inspection station includes a camera to image each work piece. The camera communicates these images to a processing unit such as a computer that can rapidly compare the image to a set of quality control standards each work piece should meet.

Abstract: A piece of material that includes low-Z elements is classified based on photonic emissions detected from the piece of material. Both XRF spectroscopy and OES techniques, for example, Laser-Induced Breakdown Spectroscopy (LIBS) and spark discharge spectroscopy, may be used to classify the piece of material. A stream of pieces of material are moved along a conveying system into a stimulation and detection area. Each piece of material, in turn, is stimulated with a first and second stimulus, of a same or different type, causing the piece of material to emit emissions, for example, photons, which may include at least one of x-ray photons (i.e., x-rays) and optical emissions. These emissions then are detected by one or more detectors of a same or different type. The piece of materials is then classified, for example, using a combination of hardware, software and/or firmware, based on the detected emissions, and then sorted.

Abstract: A flow cytometer subsystems monitors a particle sensing zone within a fluid transport chamber for the presence of a particle (e.g., blood cell) traveling therethrough, and produces an output pulse, whose width is representative of the trajectory and thereby the length of time that the particle is within the particle sensing zone as it travels through the fluid transport chamber. This output pulse is then processed in accordance with geometry parameters of successive time delay zones of the particle fluid transport chamber through which the particle passes, in order to derive a composite time delay between the sensing of the particle to the time at which a fluid droplet containing the particle will break off from the carrier fluid. The composite time delay is employed to accurately establish the time at which the particle is controllably charged as the particle breaks off from the carrier fluid.

Abstract: The present interdependent group of inventions pertains to methods of and devices for lump separation of raw material and may be used in ferrous and non-ferrous metal ore dressing, concentration of mining and chemical raw materials, processing secondary raw materials and technological wastes. The method and the device are based on the idea that a lump comprises a useful component and refuse, and such lump is exposed to ultrahigh frequency (UHF) electromagnetic field. The frequency selected is such that electromagnetic wave penetration depth will exceed the maximum linear size of a lump under conditions of maximum damping of electromagnetic wave, which depends upon characteristics of such lump material. The energy of UHF electromagnetic radiation absorbed by a lump material causes heating of the lump components. A component with higher electric conductivity will absorb UHF energy higher than UHF energy absorbed by a component with lower electric conductivity during the same period of time.

Abstract: Use of more exotic laying patterns in connection with establishing paving stones of concrete blocks for e.g. paving on yards, are not widely used for cost reasons, as the automated laying machines laying the said paving stones in large surfaces at a time require the stones to be delivered in palletised formats which are handled by machine. The only way in which the said stereotype formats can be laid by machine is, if the paving stones are supplied manually, patterned layers on pallets. There is thus indicated a method for automatic sorting of paving stones (2) of different size from bulk condition to e.g. patterned laid palletisable layers in a standard out format, as the stones (2) after being guided into a row (3) are registered by size by a vision based system and guided into arraying lanes (34) from where these may selectively be dispensed in the preferred laying patterns in the said out formats (22).

Abstract: A counting system for a poultry processing plant that uses conveyors is disclosed. Two types of conveyors are addressed, one where poultry hang from the conveyor and one where the carcasses are supported above the conveyor. The sensors are located at different levels to sense elements of the carriers as well as poultry. Logic within the system compares the readings of the sensors to determine whether a chicken is present and whether to increment the total. Additionally, the sensors are recessed in steel tubing on mounting plates which support their own cover plates. The sensors can thereby be adjusted for alignment while the cover plates move with the sensors. The cover plates are easily removed for cleaning and put back into position without blocking the sensors. Air is blown through the steel tubing to keep a positive air pressure in the tubing to prevent dirt from entering the openings.

The micromechanical actuator thereby sorts the cells individually, with an operation rate of 3.3 kHz, however with the massively parallel 1024-fold device described herein, a throughput of 3.3 million events/second is achievable.

The subsystem is operative to illuminate a respective droplet monitoring location along each of one or more droplet travel paths with a respective beam of light, such as that sourced from a common laser. In response to backscatter reflection from a droplet passing through the respective beam of light at a respective droplet monitoring location, the amplitude of the beam of light is increased. Then the droplet is monitored for the presence of a particle therein exhibiting detectable fluorescence as a result of the increase in the amplitude of the respective beam of light.

Abstract: A micromechanical particle sorting chip uses an actuator divided into two parts to direct a component of interest into one of a plurality of possible exit paths, based on detection of a fluorescent signal emanating from the component of interest. The two-part actuator may include a force-generating portion and a microactuator portion. The microactuator portion may be disposable, whereas the force-generating portion may be reuseable.

The force-generating portion and the microactuator portion may be optimized and fabricated separately, thereby leading to faster, more reliable and less expensive particle sorting.
