Abstract: An instrument preferably employable for a vehicle includes a dial and at least one pointer for indicating the present operative state of the vehicle such as a running speed, an engine speed or the like through a window glass. The dial is illuminated from the rear side by activating a dial illuminating unit, while the pointer is illuminated indirectly via a reflective coating film formed thereon by activating a pointer illuminating unit. The pointer is rotated in a normal direction via a stepping motor when an ignition key is shifted to ON, while it is rotated in a reverse direction when it is shifted to OFF. The instrument is additionally provided with a pointer mask plate made of an opaque plate-shaped material and placed between the window glass and the pointer. The pointer mask plate is located below a zero calibration on the dial and at least the window glass side of the pointer mask plate is blackened without any optical brightness like a frosted glass.

Abstract: A line-of-light illuminating device includes an optical lightpipe for receiving and transmitting light by internal reflection and an integral optical lens located at an emission portion of the lightpipe for focusing the reflected light into a collimated line-of-light beam. The lightpipe and lens are preferably injection molded in a single shot as a unitary device. The lightpipe preferably has an isosceles triangular cross-sectional shape with an apex formed at the point where the two equilateral sides join. A reflective surface is formed along the apex on the emission portion of the lightpipe, and the lens is located on the side opposite the apex. The internally reflected light striking the reflective surface is reflected perpendicularly therefrom to the lens. The lens focusses the reflected light into the collimated line-of-light beam.

Abstract: An exterior framing projector is adapted for use in all weather conditions and includes a hermetically sealed housing with the clear cover over one end through which the light image is projected. The components of the projector are mounted and sealed within the housing and may be positioned on a base carried in the housing with the various components mounted in a manner to be adjusted relative to one another to control focus and image size. A lamp positioning system is provided for assuring accurate alignment of the lamp with the ellipsoidal reflector of the projector.

Abstract: A lantern having a base, a globe, and a top is provided with a slidable shutter which is movable between an open position in which light can shine through the globe throughout 360.degree. and a closed position in which the shutter blocks light from shining through a portion of the globe. The globe has a generally rectangular transverse cross section provided by a pair of generally flat front and back surfaces and a pair of generally flat side surfaces. The shutter is slidable within a pair of tracks which are provided by ribs which extend along the sides of the back surface. The shutter is releasably latched in the closed position by a pushbutton latch on the top of the lantern.

Abstract: A light guidance system for the illumination of an interior area with a light deflection device which reflects daylight coming from outside of the interior area as well as artificial light coming from inside of the interior area. The light deflection device comprises several elements disposed parallel to one another and spaced apart from one another such that light from outside of the interior area can penetrate through the space into the interior area, and each of said several elements has at least one reflector surface and is impervious to light.

Abstract: A dual mode exterior lamp for an aircraft includes a higher intensity anticollision light, a lower intensity recognition light, a power supply for the lights, and means for activating the anticollision light when the aircraft is airborne and for activating the recognition light when the aircraft is on the ground. In the preferred embodiment the activating means is responsive to a landing gear position switch.

Abstract: The invention concerns a lamp having a reflector, a glass lid and a filament which is supported by supply wires. The supply wires pass from the interior of the lamp to the outside through the connecting area between the reflector and the glass lid. The reflector is thus almost 100 percent effective because there is no space required for a material collection marking a passage of supply wires or a socket for receiving a bulb. The light performance of the lamp is thus an optimum.

Abstract: A headlamp for motor vehicles has a reflector, a gas discharge lamp, a front plate covering a light exit opening of the headlamp, and a filter arranged in a beam path of light beams reflected by the reflector and light beams transmitted directly to the front plate and at least partially absorbing light in a UV wavelength region.

Abstract: A lubricating arrangement for an automatic power transmission has a lubricant circuit for communication between a pressurized fluid source and a component of the automatic power transmission to be lubricated. A flow restriction means is disposed within the lubricating circuit. The flow restriction means incorporated in the lubricating arrangement introduces a twin choke construction for providing sufficient magnitude of flow restriction for the lubricating fluid supplied from the pressurized fluid source for preventing excess fluid from flowing through the lubricating circuit which causes a drop of supply pressure and/or flow rate in the pressurized fluid source and blocking of the fluid flow path due to accumulation of foreign matters, such as dust, dirt and so forth. The flow restriction means comprises a first choke and a second choke arranged in tandem fashion across a fluid reservoir provided therebetween.

Abstract: A combination flashlight-baton has a head assembly connected at one end of a flashlight barrel which houses a substantially parabolic reflector, a planar lens, a lamp bulb receptacle, and a lamp bulb. A battery source of power is contained within the barrel and a switch on the barrel energizes the lamp bulb. A baton assembly carried in the tail end of the flashlight barrel has telescoping tubular members movable between a retracted position substantially within the barrel and an extended position extending outwardly therefrom. The innermost tubular telescoping member has a small mass at the distal end. With the baton retracted, the combination flashlight-baton can be carried, stored, and used as a conventional flashlight. To extend the baton, the user holds the flashlight by the handle with the tail end pointing away and sharply snap the wrist forward in a slinging action and the telescoping members are extended outwardly due to centrifugal force.
