  • Patent number: 5374191
    Abstract: An enhanced deck for generating live fire simulations of fuel spill and chemical fires and the like includes a receptacle for receiving a volume of fluid such as water within which is mounted a fuel burner array. Gaseous or liquid fuel is delivered to the burner assembly under pressure, resulting in the expulsion of fuel into the liquid, where the fuel transforms into vapor and rises to the surface of the receptacle. A support surface such as a metal grating or other rigid temperature resistant structure is provided at the upper end of the liquid receptacle and is at least partially immersed in the liquid so as to be in heat transfer relationship with the support surface. The fuel vapor is ignited at the support surface to generate a training fire. Preferably, a flow of liquid is provided to the receptacle to replace liquid that evaporates from the heat of combustion to maintain the support surface at or below a predetermined temperature.

  • Patent number: 5372508
    Abstract: A training device for the graphic representation of the fluidic processes and functions for basic and advanced fluidics training, with an essentially vertically oriented panel, on which fluidic practice devices are mounted in a systematic arrangement and are controllable by means of directly or indirectly operated directional valves through permanently installed tube connections to create various functional flow path patterns, is improved upon with regard to its handling characteristics and its instructional utility. Toward this end it is provided that each practice device is coupled with a movable symbol plate (12) on the face of which the flow-path alternatives (13) of the practice device are indicated, and that the movement of the symbol plate (12) is directly translatable into the hydraulic loading of the practice device.

  • Patent number: 5362240
    Abstract: An apparatus and method for language teaching is provided, which includes use of a microphone for receiving a statement by a person in the language sought to be learned. A first signal is created, and the first signal is subjected to a first processing step to create a second signal. The second signal contains the first signal in a modified form, in a predetermined manner according to the envelope curve derived from selected pass bands of the language sought to be learned. The first signal is subjected to a second processing step to create a third signal which contains the first signal modified according to the harmonic content of the statement and according to the characteristics of the language. Finally, either the second or third signal is sent to the person, depending upon whether the amplitude of the first signal is above or below a predetermined threshold.

  • Patent number: 5358407
    Abstract: A selection of scaled photographic images of appearance modifications are printed with opaque backing on clear transparent overlay sheets. An instant color photograph of a user is removably attached by Velcro to an opaque carrier page. The overlay sheets each overlay the carrier page one at a time to view what the user would look like with the appearance modifications. Overlay sheets are bound together in a spiral binder to permit ease of use and storage and updating with replacable pages. A scaled viewing guide slides removably into a slotted U-shaped holder around the camera viewfinder. Additional views of the appearance modifiers viewed from different angles and information and images of products related to the appearance modifiers may be printed on each overlay sheet.

  • Patent number: 5354203
    Abstract: Apparatus for training an operator in use of hydraulic and electrohydraulic fluid power systems that includes a vertical panel upstanding from a wheeled base. A first plurality of electrohydraulic devices are mounted on one side of the panel, and second plurality of hydromechanical devices are mounted on the opposing side of the panel. Both of the device pluralities include fluid flow control valves that are distinct from each other between the respective pluralities, and fluid load devices such as rotary hydraulic motors and linear hydraulic cylinders that are shared by the respective pluralities. A fluid power source is carried by the base, as are a multiplicity of hoses for connecting the fluid power source to the devices among either or both of the first and second pluralities. Thus, a hydromechanical trainer and an electrohydraulic trainer are provided in a single device with shared components for loading the valves of the respective training sections, which may be used simultaneously.

  • Patent number: 5346396
    Abstract: A wax pattern is built up on the surface of the other end of a post comprising pure titanium. The wax pattern is used to produce a casting mold. While the casting mold is kept at a predetermined temperature, a crystallized glass having a thermal expansion coefficient falling within the range of .+-.5.times.10.sup.-7 with respect to that of pure titanium is melted and cast in the mold. The resultant mold product is heated and crystallized to obtain a dental prosthesis. A post comprising pure titanium is chemically bonded to a core comprising the crystallized glass. This invention provides a dental prosthesis which is easy to manufacture and nontoxic to the human body.

  • Patent number: 5342201
    Abstract: There is disclosed a method of manufacturing artificial tooth restorations for natural teeth or implants comprising a ceramic densely sintered, high-strength individual core B with dental porcelain A by powder metallurgical manufacturing methods. The inner surface I of the core B, which will fit against one or more prepared tooth surfaces P or artificial abutments, is manufactured by forming a ceramic powder mixture against a surface of a body at which this mentioned surface is manufactured by registering the surfaces of the prepared teeth or artificial abutments and their mutual relationship with a three-dimensional optical or mechanical reading method directly in the mouth or on a model of, e.g., plaster, after which the registered surfaces are reproduced in an enlarged size, e.g., with a computer-controlled milling machine. The amount of enlargement is calculated from the shrinkage of the ceramic material during sintering to full density and considering the gap for cement.
