  • Patent number: 5698328
    Abstract: Doped and undoped polycrystalline and noncrystalline diamond films produced by plasma enhanced chemical transport emit electrons into a vacuum in response to an applied electrical field. The field required to create emission is less than 20 V/.mu.m for doped polycrystalline films, can be in the range of 5 to 8 volts/.mu.m for undoped nanocrystalline films and may be 3 volts/.mu.m or less for doped nanocrystalline films. These materials exhibit emission properties which are continuous across the whole surface of the film.

  • Patent number: 5687641
    Abstract: This invention relates to a method and apparatus for handling stretchable sheet material, to form a stack of leaves of such material. In particular, although not exclusively, the invention concerns the handling of dough sheets in the manufacture of biscuits or other baked foodstuffs. A first conveyor carries leaves of the material which are transferred to a second conveyor where the leaves are transported in a stacked configuration. Transfer is accomplished by use of an overhead permeable, suction surface movable between the first and second conveyor.

  • Patent number: 5682330
    Abstract: A method of observing and comparing the visual and textual record of repetitive or related events, such as behavioral activities, recorded on a viewable media, which includes converting the visual record into a digital format, storing the digital record in a database at an identifiable location, establishing and storing a textual database comprising written descriptions of the visual record and a glossary of key words identifying repetitive events, the stored information constituting an information library. The library is stored in a microprocessor system, the microprocessor being programmed so that a user can search and retrieve multiple images of a selected event, precursor visual images of events prior to the event in time, responsive activity showing events subsequent to the selected event and contemporaneous events, all retrieved visual images including textual information.

  • Patent number: 5666531
    Abstract: The Recording Technique provides a directory which indicates the location of only the last version of any stored information or modified entry of stored information, prior versions being transparent to the operating system. The Recording Technique further provides a directory recorded on the CDROM which is transportable to other computers having the Recording Technique installed thereon. As a result, the user of a computer with a CDROM reader will interface with the CDROM in the same manner as with a non-volatile memory device that is read only.

  • Patent number: 5617719
    Abstract: A vapor-air steam engine is described which operates at high pressure and utilizes a working fluid consisting of a mixture of compressed air, fuel combustion products and steam. In the new cycle described working fluid is provided at constant pressure and temperatures. Combustion air is supplied adiabatically by one or more stages of compression. Fuel is injected at pressure as needed. From 40% to all of compressed air is burned. Water is discretely injected at high pressure to produce steam and thus provide an inert high specific heat diluent required for internal cooling of an internal combustion turbine or other type system. The use of extensive water injection inhibits the formation of pollutants, increases the efficiency and horsepower of an engine, and reduces specific fuel consumption. The new cycle may also be operated open or closed; in the latter case, water may be recouped via condensation for regenerative reuse.

  • Patent number: 5611169
    Abstract: A clip for attaching a fishing hook to an elongated line, the clip having a first portion configured to clamp onto the line, the hook being attached to the clip at a second end spaced from the first portion. The clip further includes first, second and third legs extending from the first portion, the third leg having a camming portion such that pressing the line against an external surface of the camming portion and pulling the clip toward the hook attachment point results in the line becoming inserted into the first portion and pressing the line against an internal surface of the camming portion and pushing the clip in a direction opposite of the hook attachment point results in the line being released from the clip.

  • Patent number: 5581499
    Abstract: A device for optically storing and retrieving information incorporating a cadmium fluoride crystal. Using focused ionizing radiation, patterns can be formed in the crystal by the creation of color centers and/or intrinsic luminescence quenched areas. The stored information can then be retrieved by irradiating the crystal with visible light, ultraviolet light, ionizing radiation or combinations thereof. The device and the storage technique allows the storage of various different levels of information, the different levels being retrievable by using different irradiating media and magnifications of the retrieved information. The device and technique also allows the information to be stored for a predetermined period of time.

  • Patent number: 5553328
    Abstract: Device for rapidly and automatically deploying and retracting a combiner attached to a visored helmet. A combination of opposing springs, one made from conventional materials and the other from shape memory alloy (SMA), effects a detent mechanism and the retracting and deploying mechanism. The conventional spring normally exerts a greater force than the SMA spring, but the latter exerts the greater force upon being heated, preferably by means of an electric current passing through the spring. Alternative deployment and retraction means include a solenoid-conventional spring combination or an electrical motor which used in conjunction with a locking and unlocking means incorporating a SMA spring.

  • Patent number: 5537858
    Abstract: A sensitive to a change in the physical dimension(s) of the exterior surface of a pressure vessel transducer and attached to the exterior surface thereof the pressure vessel may be a vacuum chamber. The transducer measures exterior dimension change, representing interior pressure change information, without intrusion. The measurements are displayed using distinctive lights or audible alarms which signal if the pressure inside the vessel is within a predetermined range. If the pressure within the vessel varies outside of the predetermined range, a more precise display device such as a meter, is provided to aid facility personnel in deciding when repairs are necessary.
