Abstract: A ceiling insulation system for commercial buildings. The present invention provides an attractive ceiling panel system with a functional insulation and water vapor barrier system with an insulating R-value of 44 and a perm rating of 0.4. A hat-shaped channel is suspendable from bar joist, steel purlin, or wood joist by using one of three different suspension fasteners. A C-shaped clamp with locking ring, a cylindrical rod and two spring clamps complete the suspension subassembly. Channel junction clips and board edge clamps are used to insure the integrity of the system and enable a high insulation value and a low perm value.

Abstract: A sleeve-style beverage carton for use on a carton filling machine having traveling flight bars is disclosed. The carton may be formed in various models for use in packaging either cans or bottles and contains a novel first cut-out formed in the dust flaps of the carton. The first cut-out is sized a predetermined length to provide a cut-out area so that the dust flaps can be revolved during the filling operation to clear the traveling flight bar used in the carton filling machine. A second pair of cut-outs may be formed in the dust flaps for similar purposes. A third and fourth pair of cut-outs may be formed in the dust flaps to minimize drag in combination with the first and second pair of cut-outs on one version of the carton. A fifth and sixth pair of cut-outs may be used with one of the models shown to aid in proper alignment of the carton end panels.

Abstract: An improved method of gluing a package in an in-line packaging machine. The package is of the type having a plurality of leading and trailing end flaps which are glued to be together during the packaging process. The novel method comprises in part providing at least two glue nozzles in the line of the packaging machine direction with one glue nozzle facing downwardly and upstream while the other glue nozzle faces downwardly and downstream so that the glue is applied to a pair of the end flaps by one nozzle in an upwardly direction and by the other nozzle in a downwardly direction as the package is moved through the packaging machine past the glue nozzles. Subsequently thereafter, the other pair of end flaps are turned inwardly and are held in position after being glued until the glue sets. The four flaps of the package are turned inwardly by a first and a second flap closing means.

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.

Abstract: Mounting means for thermal insulation blocks or modules are described. The means comprises a rounded member adapted to fit into and cooperate with a C-shaped channel member attached to the block, with the rounded member itself being secured by a securing member to the wall of a furnace or like device. The mounting member allows the block to be easily secured to the wall even in locations of limited access.

Abstract: A method for measuring the concentration of a gas. The method includes circulating an electrolyte solution between an electrode and a gas-permeable, ion-impermeable membrane spaced from said electrode. The ionic concentration is measured after the circulating electrolyte has been stopped.

Abstract: An improved luminar having an adjustable lamp socket is disclosed. The adjustable socket comprises a generally cylindrical shaped socket shield which is fixed to the ballast housing of the luminar and is positioned around the lamp socket with the socket shield having formed therein a bracket channel and a guide channel. A generally U-shaped bracket is fixedly attached to the socket and has identification means formed thereon designating the relative position of the socket within the socket shield. The bracket also has formed thereon at least one protuberance for positioning in the guide channel means formed on the socket shield. The generally U-shaped bracket is positioned within the bracket channel means and is designed for movement within the channel in the desired position of the lamp in the reflector of the luminar. Locking means are provided for locking the U-shaped bracket within the socket shield at the desired pre-determined position.

Abstract: A new and improved luminaire combination is disclosed having a novel lens structure formed with a generally horizontal first lens surface and a generally vertical second lens surface with a generally horizontal flange formed on the second lens surface. The first lens surface is designed to refract a beam of light downwardly and outwardly in a predetermined pattern to form a beam having a cross section approximating the predetermined pattern at a predetermined distance below the lens. The second lens surface is designed to diffuse a beam of light outwardly in a direction perpendicular to the second lens surface.

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.

Abstract: A stepper motor positioning control utilizing phase detection of the stepper motor windings. The device utilizes crude positioning apparatus to position the attached turntable or the like in an approximate position. The phase detection of the stepper motor windings is then used to position the attached turntable in the exact location desired.

Abstract: An automated pipette employing a device to ensure exact volume pickup and delivery. An optical device senses the presence of a liquid in the tip of the pipette. By intaking the volume past the optical device stream continuity is determined.

Abstract: A container for comparative testing of a sample substance. The container includes a plurality of side-by-side compartments into which a sample substance may be injected. A cover and seal protect the compartments from the outside atmosphere. A sample substance may be injected through the cover and the seal which then reseals itself upon withdrawal of the injecting probe. Level indicator lines on each compartment provide an indicator to ensure the exact amounts of substance being placed in each compartment.

Abstract: A magnetic stirring arrangement for stirring sample material held within a cylindrical glass sample container for assay.
