Abstract:
A method for starting and operating a preheat type fluorescent lamp includes a source of alternating current, a fluorescent lamp having a low impedance starting mode wherein current passes through one or more starting filaments and a high impedance operating mode wherein current passes through the length of the lamp, a starting switch directing current through the starting filaments in the lamp starting mode, and an inductor ballast having a magnetically permeable core operating in a saturated condition when the lamp is in the low impedance starting mode and in a non-saturated condition when the lamp is in the high impedance operating mode.
Abstract:
A bow saw useful for camping, backpacking, tree pruning, wood cutting, and like outdoor usages particularly, which comprises a rigid tubing having opposed differentially dimensioned distal and proximal ends defining opposed saw blade receiving slots in a common plane, a saw blade having differentially proportioned distal and proximal end portions singularly orienting the blade relative to the bow in the bow slot received condition of the blade, and blade retaining apparatus carried by the blade within the bow tubing in blade distal and proximal end portion defining relation.
Abstract:
A fluorescent lampholder fitting has a preheat type circular fluorescent lamp with its ends in proximity and having a first end provided with a starting filament with a first and second filament terminal wire, and a second end provided with a second starting filament with a first and second filament terminal wire. A male screw base electrical connector extends axially along the lamp circle centerline from a housing which supports the lamp in a plane normal to the axis of the screw base. The screw base is provided with three electrical input connections which are adapted to be used in a three-way lampholder of a portable lamp or light fixture. A lamp starter is connected between the first lamp filament and the second lamp filament. A first ballast is connected between a center connection of the screw base and the second lamp filament, and a second ballast is connected between an intermediate ring connection of the screw shell and the second lamp filament; whereby the lamp will start and operate on the first ballast with input power applied to the screw shell and the center connection of the screw base, the second ballast with input power applied to the screw shell and the intermediate ring connection, and both ballasts in parallel with the input power applied to the screw shell and both remaining connections of the screw base.
Abstract:
A lampholder-socket is attached to a housing having a smaller cross section than a circline lamp. The housing is preferably block-shaped, having four edges parallel to the axis of the circline lamp when installed. The diagonal distance between the edges is almost as large as the diameter of the circline lamp. The lampholder-socket extends partially inside the housing and partially outside the housing. Its terminals are adapted at one end to engage the circline lamp pins outside the housing when the circline lamp surrounds the housing and are adapted at the other end to receive connecting wires of components inside the housing, preferably with a poke home connection. A support, preferably a pair of stationary fingers extending from the housing at points spaced from each other and from the lampholder-socket, hold the circline lamp in place together with the lampholder-socket when the pins of the circline lamp engage the terminals.
Abstract:
A flashlight has one or more batteries disposed in a first tubular housing section, a switch disposed in a second tubular housing section, and a lamp assembly with a light bulb disposed in a third tubular housing section. The first and second housing sections are joined by a threaded connection. The second and third housing sections are joined by a threaded connection, either directly or indirectly through a fourth tubular housing section in which one or more batteries are disposed. The switch has an elongated switch post supported to extend between two holes on opposite sides of the second housing section and to move axially toward one hole or the other without protruding substantially beyond the surface of the housing. An electrical circuit for the batteries and the bulb is opened and closed responsive to axial movement of the switch post. Diaphragms adjacent to the ends of the switch post seal the two holes. A baffle separating the lamp assembly from the batteries transfers axial inertial battery forces in the direction of the lamp assembly directly to the housing to isolate the bulb from such forces except as transferred through the housing, attenuating means, a bulb supporting reflector, and spring contacts
Abstract:
This invention integrates energy saving lighting with energy saving HVAC (Heating, Ventilating and Air Conditioning). This system is termed by the inventor “ILAC” (Integrated Lighting and Air Conditioning). An ILAC system includes light fixtures mounted in a ceiling and, emitting lamp heat into a plenum and visible light into a room. A central computer controls both lighting and HVAC systems. In a COOL mode an HVAC unit cools the room through a supply air duct and return air duct, and the lamp heat exits the plenum through an exhaust duct. In a HEAT mode the HVAC heats the room through the same supply air duct, a ceiling-to-plenum duct carries the heated room air into the plenum, and an HVAC return air duct carries room and plenum heat back into the HVAC unit that uses less power to heat the lamp-warmed return air. In a thermostat-controlled OFF mode, warm room air convects through the ceiling duct into the plenum and exhausts through a plenum exhaust duct along with lamp-heated plenum air. Optionally, plenum exhaust duct may include a radiator to transfer plenum heat to pre-heat water entering a remote hot water heater.
Abstract:
A convection-cooled recessed downlight fixture for an air-tight ceiling, having a reflector, (preferably bright aluminum) held in a hole in a ceiling with knock-outs bent down against the upper surface of the ceiling; a lamp housing (preferably black-anodized aluminum), removably attached to the upper end of the reflector, and a bezel assembly including a decorative trim element, is removably installed in the lower end of the reflector and held therein with screws removably engaging the reflector, whereby the bezel and decorative element may be removed from the fixture for re-lamping.

Abstract:
A lighting fixture has a proximal end fixture adapter connectable at a proximal end to a mounting device attachable to a ceiling. The mounting device may be an elongated track, a fixed canopy or a ceiling ring permitting a proximal portion of the fixture to be above the ceiling. The lighting fixture has a generally cylindrical housing with first and second resilient rings partially engaged into first and second external grooves around the distal end of the housing. A decorative shade has a fitter slidable on the housing and retained between the first and second resilient rings.
Abstract:
A substantially sealed case for enclosing objects has at least one openable surface and an inlet-outlet port through a surface of the case, permitting the ingestion and expulsion of air during case thermal expansion and barometric pressure changes. The inlet-outlet port has an inlet passage and an outlet passage therethrough, with a check valve in the inlet passage permitting ingestion of air into the case through an inlet filter and blocking the expulsion of air therethrough. The inlet-outlet port also has a check valve in the outlet passage permits the expulsion of air from the case through an outlet filter and blocks the ingestion of air therethrough. A flexible membrane bag encloses the inlet and outlet filters, and may optionally include air treatment means for controlling the relative humidity and the oxygen content of air in the bag.
