  • Patent number: 4496905
    Abstract: A testing device for electrically analyzing electrical failures in high pressure sodium lighting fixtures is disclosed. The testing device is inserted in the lighting fixture after the sodium lamp has been removed and contains three indicator lights. The user of the device compares the condition of the indicator lights with a chart on the label of the device to determine the type of failure. The circuit analyzer device will give distinct indications for a defective lamp, a defective circuit starter board, and a defective ballast and capacitor, thereby allowing the user of the device to make any necessary changes in order to return the lighting fixture to service. A pair of rectifier diodes are installed in a reverse direction so that the pulse to the lamp must be at least 2500 volts in order to break over the diodes PRV rating and to light the appropriate indicating lamps.

  • Patent number: 4481746
    Abstract: A mini-module for insertion into gaps between adjacent refractory fiber blanket modules lining a furnace. This mini-module is formed by folding the ends of a length of refractory fiber blanket toward each other, preferably forming a butt joint. This butt joint is positioned nearer the cold face of the module than the hot face thereby protecting the fiber ends exposed in the blanket ends from damage (e.g., shrinkage).

  • Patent number: 4456649
    Abstract: This invention relates to holt melt adhesives for use in coating and/or laminating paper. Conventional hot melt adhesives used to manufacture a coated or laminated product with good vapor barrier characteristics are based on ingredients compounded with significantly lower proportions of inert low cost filler materials. The present invention provides a hot melt adhesive/coating blend which not only provides a moisture vapor barrier and/or bonding but also significantly reduces the quantity of more expensive ingredients through the use of a large quantity of a lower cost ultra fine ground inert inorganic filler material and a low cost modifying hydrocarbon resin. The blend or composition consists essentially of, in parts by weight, up to about 25 parts of a hi melt point paraffin wax, 10-30 parts of a modifying hydrocarbon resin, 1-20 parts of an elastomeric copolymer, and 20-85 parts of an inert inorganic filler material.

  • Patent number: 4450873
    Abstract: A reinforced plastic composite structure, particularly a pipe, is disclosed herein. The composite pipe, which resists acid attack even in underground applications where the pipe is subjected to external loading stresses, typically includes at least an inner zone, e.g. a resin impregnated fibrous sheet and an outer zone including a layer or layers of fibers. A cured polymeric resin matrix bonds the fibrous sheet and the fibrous layers together in a laminar relationship. The improvement disclosed herein comprises incorporating into this polymeric resin matrix a particulate substance which has specific particle size limitations and which is selected from the group consisting of portland cement, marble dust or a mixture thereof.

  • Patent number: 4451762
    Abstract: A control circuit and system is disclosed for providing emergency lighting from a single source of electrical power which itself is capable of providing input power alternately in the form of a sinusoidal power signal and a square wave power signal during interruption of the sinusoidal power signal. In the preferred form of the invention, a high intensity discharge lamp (HID) and an emergency lamp are provided in the same lighting fixture. A control circuit in the form of a power source detector first detects whether a sinusoidal power signal or a square wave signal is being supplied from a power station onto a pair of input lines. The power station automatically supplies the detector with input power in the form of a square wave rather than the normal sinusoidal power signal when an emergency condition exists such as normal power failure.

  • Patent number: 4449633
    Abstract: A new and improved ovenable paperboard carton for use in a microwave and conventional oven is disclosed. The improved carton comprises a bottom tray having a plurality of side panels with gusset panels attached thereto and combines the bottom tray with a new and improved upper lid which has a central top panel and a plurality of side panels hingedly attached thereto. The upper lid contains a pair of strategically placed reverse cuts which form a tear-off portion for the carton. The tear-off portion is designed to provide corner reinforcement to the package. When the tear-off portion is removed from the upper lid, a pair of structurally supporting channels are formed along opposite edges of the carton to add stability, with the corner reinforcement, to the package upon removal of the lid. The upper lid is adhesively secured to the bottom tray to further enhance the rigidity of the package.

  • Patent number: 4439175
    Abstract: A machine for forming blocks of fibrous insulation from a continuous fibrous blanket. These folded blocks may be used in furnace linings or the like. A pair of oscillating folder vanes form folds which extend in alternating directions. The vanes are oscillated by a continuously driven motor through a crank linkage. A reciprocating support vane engages the newly formed folds and supports them while the folder vanes are being disengaged from the blanket. A feeder drum and bearing member co-act to form a material supply loop from which the folds are made. The same motor drives all moving parts making the controls simple and inexpensive.
