Abstract: An integral, lightweight, animal feeding device is disclosed. The device has a first bottom, bowl-shaped section joined to a narrower second section which, in turn, is joined to a wider third section. A tray is located at the top of the device. The tray contains a continuous flange comprised of least three substantially linear sides, one of which is longer than the other two; the longer, substantially linear side is coplanar with a portion of the bowl-shaped bottom section.

Abstract: A visual signaling apparatus including an enclosure having an aperture, and defining a cavity, a light source for emitting light in predetermined wavelengths borne by the enclosure and positioned in the cavity; and a semi-transparent dichroic mirror borne by the enclosure and disposed in substantially occluding relation relative to the aperture, the semi-transparent dichroic mirror adapted to selectively reflect ambient light and transmit the predetermined wavelengths of light emitted by the light source.

Abstract: A heads-up display for moving vehicles such as an airplane or automobile and which includes a transparent sheet which may be the windscreen or windshield of the vehicle. An extremely thin enhancing film is secured in intimate contact with the transparent sheet and disposed within the sheet, if it is a laminated sheet such as a safety glass sheet or on that side of the sheet which is on the interior of the vehicle, or which may be made integral with the composition which makes up the transparent sheet. The enhancing film is an absorber or blocker of selected lightwaves which match the lightwaves of a display of indicia projected against the interior side of the windscreen. The assembly of film in sheet eliminates the need for a separate, independent indicia reflector to replace between the windscreen and the operator of the vehicle.
