Super-cooled extraction techniques are taught. Likewise, according to embodiments methods provides 100% grain ethyl alcohol extract with a concentration of chlorophyll that is below 1%.

Abstract: There is provided a fuel oil amount indicator of a measuring apparatus in which a lifetime of the indicator can be prolonged, maintenance work can be omitted, and visibility can always be improved. In the indicator of the invention, a plurality of light emitting elements are arrayed in a matrix form, and as the light emitting elements, high-luminance LEDs are used. An outside light sensor provided in the vicinity of the indicator detects brightness of outside light, and a light emission intensity of the light emitting elements is changed in accordance with the thus detected brightness. The light emitting elements have a plurality of luminous colors predetermined to correspond to a type of fuel oil. The indicator is provided with inclination means for inclining a display surface in response to an operation of an angle adjustment operating portion. The indicator is further provided with a diffusion plate for diffusing light to a front face of the light emitting elements.

Abstract: An illumination apparatus and an image production apparatus including a plurality of laser beams are disclosed wherein a variation of the intensity distribution caused by a secular change or the like can be compensated to obtain illumination light having a high degree of uniformity even if some laser beam exhibits a drop in intensity or misses. The illumination apparatus includes a light source section including a laser light source, an optical system into which a plurality of laser beams are introduced, and a detection section for directly or indirectly detecting a light intensity distribution on a focal plane of the optical system. The illumination apparatus further includes an adjustment section for varying the light intensity distribution on the focal plane based on the detection information of the detection section.

Abstract: An apparatus and method for cycling power to a HID ballast and amp in order to reduce the possibility of arc tube rupture or non-passive end of life light source failure with a warning indicator indicating impending momentary power outage. The apparatus comprises a lamp, a ballast, and a microcontroller operable to generate a warning indicator after expiration of a pre-selected period of time. The warning indicator indicates termination of power to the lamp for a predetermined period of time, by alternatively dimming and increasing the light output of the lamp. After expiration of the pre-determined period of time, the microcontroller restores the power to the ballast. The above described process is repeated periodically in order to reduce the risk of arc tube rupture.

Abstract: A hand held lighting device having a luminescent body for providing a light source in the absence of light. The hand held lighting device includes a housing having an outer curved wall surface and an end wall. The housing includes an attached lamp assembly having a light bulb, a reflector member and a lens therein. The housing also includes a battery cover and an interior compartment having a battery section for receiving one or more batteries for supplying power to the lamp assembly. The hand held lighting device includes a switching device in the housing for switching the lamp assembly to battery power in order to energize the lamp assembly.

Abstract: A drive mechanism for revolving the turret of a searchlight assembly. The turret is rotated in an oscillating manner over an arc of less than 360.degree.. It is particularly characterized by smooth reversal allowing the driving of a high inertia turret without rapid motor overload and failure as characterized by other prior art methods of driving such mechanisms. A partial cylindrical track is concentrically disposed about the axis of rotation and attached to the turret. In the preferred embodiment, a link chain is welded along the bottom of the track, being folded back on the ends in a tear-drop shape. A drive sprocket on a swing arm is held into engagement with the chain and driven by a constant speed motor. The sprocket alternately drives along the inside of the chain and the outside of the chain smoothly traversing between the positions around the tear-drop ends to cause a smooth deceleration and acceleration.

Abstract: An easy-to-assemble, self-locking, low brightness louver for a fluorescent lamp lighting fixture is comprised of a plurality of longitudinally-extending light baffles which are aligned at right angles to a corresponding plurality of transversely-extending light baffles. The baffles are assembled and locked with snap-type action in a criss-crossed grid-type lattice arrangement to form a unitary structure.

Abstract: A light projector for providing uniform surface area illumination of the type utilized in motion picture studios or the like, employs a housing having a reflector arranged at one end and a Fresnel lens arranged at the other end. At least two linear light sources are located in the interior of the projector at right angles to the optical axis and are electrically connected to a three-phase energization circuit. The lamps are arranged in a star-shaped pattern, relative one to another, and each is a single, self-operating, interchangeable unit, such that by replacing only one of the lamps in the light projector the color temperature of the illumination may be maintained approximately at the desired value.

Abstract: A light projecting apparatus consists of a concave, substantially prolate-spheroidal reflector having a major axis coincident with the optical axis of the apparatus and a metal halide high intensity discharge source positioned at a first focal point of the reflector and inclined with respect to the optical axis of the apparatus at an angle of approximately 30.degree.. .Iadd.
