  • Safety electrical tap
    Patent number: 4867693
    Abstract: An electrical power tap is provided with at least one shutter mechanism to block spurious insertion of a foreign object through one blade slot short of the power circuit contacts of an adjacent pair of plug receptacles. This mechanism includes a pair slides supported for independent movement between closed-latched and open positions. Access to the contacts of either power tap plug receptacle requires that its slide first be unlatched by a blade penetrating one slot and then cammed to the open position by another blade penetrating the other slot, as occurs incident to the insertion of a standard electrical plug.

  • Xenon lamp particularly suited for automotive applications
    Patent number: 4868458
    Abstract: Disclosed is a xenon lamp used for lighting applications and which is particularly suitable for automobile applications such as headlamps. The benefits of such usage, relative to incandescent lamps commonly employed for automotive forward lighting applications along with discharge lamps for lighting application, are primarily related to the size, shape, quality and concentration of the light generated by the xenon lamp and the ability to selectively move the position of the generated light relative to the reflector in which the xenon lamp is housed. The xenon lamp also provides the ability for the light to be generated by excitation of a D.C. source so as to be first positioned relative to the reflector to serve as the light source for low beam applications and then moved to a second position relative to the reflector to serve as the light source for high beam applications.

  • Forward illumination lighting system for vehicles
    Patent number: 4868718
    Abstract: A lighting subsystem is disclosed that uses optical devices to alter, the actual or apparent optical position of the ends of optical fibers coupled to a high intensity light source so as to provide all of the forward illumination needs for a vehicle. In one embodiment, optical wedges are interposed between a rectangular array of optical fibers and an array of lens elements mountable on the front of a vehicle from which the forward illumination is transmitted therefrom. The imposition of the optical devices alters the actual or apparent optical position of the fibers relative to the lenses and thereby changes the forward illumination from its low to its high beam pattern, to a fog beam illumination or to a cornering illumination pattern. In another embodiment, flat shaped optical members are rotated to provide the various forward illumination needs of the vehicle.

  • Ceramic lamp end closure and inlead structure
    Patent number: 4868457
    Abstract: The life and performance of high pressure sodium vapor lamps using double wire ceramic seals and no exhaust tube is improved by an end closure and inlead structure which prevents condensation of sodium-mercury amalgam on sealing frit. One end of the arc tube has a plug portion which forms an integral part of the alumina tube without any sealing frit or glass intervening between portions. The plug portion includes a pedestal portion which projects inwardly from the outer region which is joined to the tube. The pedestal defines with the tube wall a ring chamber in which excess amalgam collects out of contact with any sealing frit. The other end of the tube is conventionally sealed by using sealing frit to cement an alumina plug but it is designed to run hotter to prevent condensation of amalgam at that end.

  • Monolithic microwave phase shifting network
    Patent number: 4857777
    Abstract: A phase shifting network with multiple outputs between which a constant phase difference is maintained over a large frequency range. The configuration consists of a four branch all pass network which in turn consists of four similar all pass networks one in each branch. An in phase and an out of phase input signal are applied to this network and four signals in phase quadrature, 0.degree., 90.degree., 180.degree., and 270.degree. may be obtained from the network. The network is designed for operation at frequencies of micro and millimeter wavelengths and may be realized from resistive and capacitive elements fabricated upon a common monolithic substrate. A suitable substrate is gallium arsenide, permitting both passive and active elements to be formed and interconnected by lithographic techniques.

  • Current interruption operating circuit for a gaseous discharge lamp
    Patent number: 4857810
    Abstract: A power supply system for discharge lamps employs a current interruption circuit to control current flow through a discharge lamp. A power switch is connected in series with the lamp and controls the current level in the lamp by controlling lamp current on-time. The current on-time is maintained for a relatively very short time period allowing control of lamp current by controlling the integral of the lamp current or controlling the charge delivered to the lamp during each pulse rather than controlling peak current value. Since the voltage impressed across the lamp generally exceeds the conventional value observed when using a passive current limiting means, for example a series reactor, non radiative losses associated with operating the lamp are reduced.

  • Rapid restrike metal halide lamp and a method of operating such
    Patent number: 4853597
    Abstract: A rapid restrike metal halide lamp and method of operating such a lamp are disclosed which are particularly suitable for sports stadium lighting applications. The rapid restrike metal halide lamp has an arc tube containing constituents which require a waveform having a relatively high voltage and at a relatively high current in order to rapidly restrike the arc tube after the lamp has experienced a power interruption so as to initiate a sustaining arc condition of the arc tube. The relatively high waveform in the form of a series of pulse trains is routed to the arc tube by means of a two path arrangement comprising a conductive base at the bottom of the lamp and a insulative cap at the top of the lamp. This two-way path substantially reduces and even eliminates any arcing condition within the confines of the lamp.

  • Low pressure mercury discharge fluorescent lamp utilizing multilayer phosphor combination for white color illumination
    Patent number: 4847533
    Abstract: A low pressure mercury discharge fluorescent lamp is disclosed utilizing a particular phosphor blend deposited on a calcium haloapatite phosphor base layer to achieve white color lamp illumination efficiently with improved color rendition. The surface phosphor layer is a blended mixture of a first phosphor which is divalent europium barium and/or strontium magnesium aluminate having a hexagonal crystalline structure and which further includes coactivation by divalent manganese ion sufficient to produce substantial green color emission with a second phosphor which is trivalent europium activated rare earth oxide having a rare earth ion selected from yttrium, gadolinium and lutetium, including mixtures of these rare earth ions. The underlying calcium haloapatite layer also exhibits emission at approximately the same color point as achieved with the surface phosphor layer.

  • Method of forming a channel
    Patent number: 4845014
    Abstract: A method of forming a variable width channel in a body comprises the steps of forming a surface grating having a photoresist layer thereon. The photoresist layer has a plurality of depressions and a planar photomask is then positioned over the photoresist layer. The photoresist layer is subsequently exposed and developed and due to the divergence of light into the depressions covered by the photomask, forms a variable width opening. A portion of the body exposed in the opening is removed to form a channel with a sidewall having a surface contour corresponding to an edge of the opening.
