  • Patent number: 5229121
    Abstract: A hunter's face is camouflaged by applying colored fluids which dry to form a peelable film. The fluids are used to produce a camouflage pattern which comprises splotches or stripes having colors comprising black, brown, green, yellow, white and gray. In addition, the camouflage pattern can be formed by applying colored fluids over a base layer of peelable film. The camouflage is easily removed by peeling it off the hunter's face.

  • Patent number: 5221556
    Abstract: The present invention relates to improved injectors for use in CVD reactor systems, and more specifically for use in epitaxial deposition systems for processing a single water-at-a-time. The improved injectors of the present invention are used to provide a predetermined desired shaped velocity profile for the injected reactant gases for insuring a more uniform deposition on a single wafer to be processed within the reactor system. In the first embodiment, the reactant gas is fed into a horizontal gas distribution manifold cavity and distributed horizontally in both directions. The gas then passes through a manifold wall having a pattern of predetermined sized and spaced apertures therein. The size of the apertures and the distribution of these sizes, shapes the resultant velocity profile to a desired pattern.

  • Patent number: 5217745
    Abstract: Method and apparatus for applying a programmable pattern to a succession of moving objects, comprising a microprocessor for storing a user defined value representing the length of the pattern, a clock for generating a series of pulses and a photo-eye for detecting the presence of the succession of moving objects. Upon detecting the presence of a first one of the moving objects, a set-up mode gate is enabled for transmitting the clock pulses to a first divider circuit. The first divider circuit divides the number of transmitted clock pulses by the user defined value and in response generates and stores a first count value. Upon detecting the presence of subsequent moving objects, a run mode gate transmits successive predetermined numbers of clock pulses to a second divider circuit. The second divider circuit divides the successive predetermined numbers of clock pulses by a first count value and in response generates successive further count values.

  • Patent number: 5217744
    Abstract: A kit and method for testing the color of paints to be applied to painted surfaces having primers or sealers thereon to determine if a paint color matches that of a painted surface. Preferably, the kit comprises a plurality of testing members removably mounted therein or thereon. The testing members have different primers or sealers thereon corresponding to those on different known painted surfaces. When a paint is to be applied to an area of a specific painted surface, the paint is first applied to one of the testing members having thereon the same primer or sealer as that on the painted surface. The painted testing member then is moved to a position adjacent the painted surface to compare the color of the paint on the testing member to that of the painted surface.

  • Patent number: 5213847
    Abstract: Electrostatic fluidized bed coating apparatus consists of an horizontal porous plate and a contiguous, vertical porous plate. Charged particles exiting the bed formed on the horizontal plate fall past the outer surface of the vertical plate, and are electrostatically recharged by ionized air issuing through it, thereby effectively extending the operative vertical length of the bed and substantially increasing coating efficiency.

  • Patent number: 5209369
    Abstract: A sealant membrane for preventing leakage of fluids from fluid-containing tanks and a method of application of the membrane. The membrane is deposited in a varying thickness atop surfaces of interconnected wall panels in the tank by spray application of successive coats of a sealant material, so that the coating thickness is a maximum where the greatest structural deflections can occur. The successive coats are applied with a predetermined lapse time between layers to prevent slumping of the sealant material.

  • Patent number: 5204055
    Abstract: A process for making a component by depositing a first layer of a fluent porous material, such as a powder, in a confined region and then depositing a binder material to selected regions of the layer of powder material to produce a layer of bonded powder material at the selected regions. Such steps are repeated a selected number of times to produce successive layers of selected regions of bonded powder material so as to form the desired component. The unbonded powder material is then removed. In some cases the component may be further processed as, for example, by heating it to further strengthen the bonding thereof.
