  • Patent number: 6854586
    Abstract: A conveying device with a diverter having a curved path for conveying lightweight unstable articles, such as plastic bottles having a neck portion with a neck ring thereon. The unstable articles are conveyed along a first path to different ones of plural second paths through a third path at the diverter with the third path having first and second ends alignable with the first path and different ones of the plural second paths and a middle portion maintained in a curved configuration that is varied during aligning movement of the second end. A controller controls the aligning movement of the second end, preferably along a straight path, and the unstable articles are supported by engaging members in actuating guides to urge the unstable articles along the article paths.

  • Patent number: 6736573
    Abstract: A selective conveying device is disclosed for conveying unstable articles, such as plastic bottles, having a neck portion with a neck ring thereon. Neck ring supported unstable articles are conveyed in single file along an article conveying path established by first and second guide units with the guide units having spaced connectors with neck ring engagable elements thereon spaced different distances from one another to receive the neck portions of unstable articles having different size neck portions. A first actuator, such as a pneumatic or mechanical actuator, causes relative movement between the guide units so that unstable articles are conveyed along the article conveying path on the neck ring engagable portions of the first guide unit when in a first operating position or are conveyed along the article conveying path on the neck ring engagable portions of the second guide unit when in a second operating position.

  • Patent number: 6150039
    Abstract: Method and structure are disclosed for forming a protective and/or reflectivity enhanced over coating layer, or layers, on a noble metal. A metallic binder layer, capable of forming a metallic bond with the noble metal and exhibiting good adhesion to the over coating layer, is deposited on the noble metal, utilizing physical vapor deposition, and the over coating layer is thereafter deposited on the metallic binder layer, again utilizing physical vapor deposition. The noble metal is preferably gold, but may be silver or an alloy of gold or silver, and may be deposited on a substrate. Each metallic binder layer is a thin layer, such as a layer of chromium, titanium, tantalum, nickel, cobalt, or an alloy thereof, and over coating is formed as a single dielectric layer of material or as a stack of alternating low and high indices of refraction dielectric layers.

  • Patent number: 6105359
    Abstract: An efficiency enhanced turbine engine and method are disclosed for a turbine engine having a rotor and a fluid flow path that extends through compression, combustion, and expansion or turbine stages with fluid flowing through the fluid flow path driving the rotor. The turbine engine has one or more stator-rotor-stator assemblies, and use of a flat rotor disk with turbine blades provides simplicity in fabrication and operation. Increases in pressure during combustion above the pressure at the compression stage are prevented from flowing back to the compression stage and/or capturing of fluid during combustion enables elevation of the temperature and pressure while maintaining the fluid at near constant volume during combustion, both of which enhance the efficiency of the turbine engine.

  • Patent number: 5971699
    Abstract: This invention pertains to load forming systems, especially those designed to place cased product on e.g. a pallet. The invention contemplates receiving cases at a high rate of input, and fragmenting the input, sending it to parallel processing elements of the load forming system. A layer creating subsystem has parallel processing elements, and preferably has sufficient designed throughput capacity to continue processing cases at the overall rated capacity of the case loading system when any one of the parallel processing elements in the layer creating subsystem fails. The case loading subsystem also can incoroporate parallel layer transfer elements and load forming elements.

  • Patent number: 5920388
    Abstract: Small particle identification is disclosed. A high intensity light source provides light at a sensing region for contact with small particles at the sensing region to cause resulting light that includes scattered light and emitted light due to heating of optically absorbing particles to incandescence with the resulting light terminating if vaporization of the optically absorbing particles occurs. A laser, having a laser cavity with the sensing region within the laser cavity, preferably provides high intensity laser light in the laser cavity for contact with the small particles at the sensing region. Utilizing optical detection, predetermined particle characteristic determination is enabled, including particle size and composition of optically absorbing particles.

  • Patent number: 5907575
    Abstract: Apparatus and method are disclosed for minimizing performance degradation in a laser device having a laser cavity operating in a predetermined spatial mode having predetermined light beam wavefronts within the laser cavity mode. An optically transmissive unit is placed within the laser cavity and has at least one intracavity optical surface that may be positioned at or provides one end of a laser medium that is within the laser cavity with the intracavity optical surface being coincident with the laser mode wavefronts in order to minimize power losses in the laser device due to contamination buildup at the intracavity optical surface. The optic unit may also include a second optical surface that is less exposed to contamination and has a configuration suitable for providing needed focal properties for the optic unit, and one or more of the optical surfaces may have a reflection coating thereon.

  • Patent number: 5889589
    Abstract: Intracavity particle detection is disclosed using optically pumped laser media. A laser medium, positioned within a laser cavity, is end-pumped by an optical pump source to excite the laser medium to provide laser light within the laser cavity, and a detecting region, also positioned within the laser cavity and capable of having particles, or particle-containing fluid, therein, is exposed to the laser light whereby light is affected, as by being scattered, by particles in the detecting region with the scattered light being indicative of particles, such as small particles having a size of between 0.05 and 10 microns, causing the light to be scattered so that the scattered light, when collected, can be used to provide an output indicative of particles at the detecting region.

  • Patent number: 5819907
    Abstract: Apparatus and method are disclosed for conveying different types of force responsive articles, such as steel and aluminum cans, and particularly for efficiently conveying different force responsive articles between first and second positions, including positions at different elevations. A conveyor, such as a chain, moves the articles along a predetermined path between the first and second positions with the articles maintained in engagement during movement along the predetermined path and with the conveyor using different applied forces for different ones of the types of articles to be conveyed, such as a magnetic force for conveying steel cans and a negative pressure (vacuum) force for conveying aluminum cans. A support face for the conveyor has magnets mounted thereat to establish the magnetic force and apertures communicating with an adjacent plenum to establish the negative pressure force.

  • Patent number: 5805281
    Abstract: Noise reduction is effected by multiplying together electrical signals that include pulses embedded in noise, with the pulses being indicative of the same event, such as light scattered by particles, occurring at a viewing area, and with the signals being processed prior to multiplication so that the pulses and the variance of the noise in the electrical signals are multiplied by one another. A detector in each of a plurality of channels detects the events occurring at the common viewing area and provides pulses indicative thereof, and the output from each detector is amplified, passed through matched low-pass filters to enhance pulse detection, and then passed through a baseline restorer to remove DC components from the noise then present in the signal, prior to coupling of the signals to a multiplier.
