Abstract: A security coating for business documents printed using noncontact as well as impact printing devices is provided which enhances the adhesion of toner particles and/or ink to a document substrate. Other security features may be also be added to the coating to provide a dual-function coating which also provides visible evidence of tampering, either by the application of solvents, mechanical abrasion, heat, or when pressure is applied.

Abstract: Solid membranes comprising an intimate, gas-impervious, multi-phase mixture of an electronically-conductive material and an oxygen ion-conductive material and/or a mixed metal oxide of a perovskite structure are described. Electrochemical reactor components, such as reactor cells, and electrochemical reactors are also described for transporting oxygen from any oxygen-containing gas to any gas or mixture of gases that consume oxygen. The reactor cells generally comprise first and second zones separated by an element having a first surface capable of reducing oxygen to oxygen ions, a second surface capable of reacting oxygen ions with an oxygen-consuming gas, an electron-conductive path between the first and second surfaces and an oxygen ion-conductive path between the first and second surfaces. The element may further comprise (1) a porous substrate, (2) an electron-conductive metal, metal oxide or mixture thereof and/or (3) a catalyst.

Abstract: The present invention is an envelope sheet capable of being automatically printed and formed into a standard business envelope using a high-speed separate sheet printer in line with high-speed separate sheet folding and pressure sealing equipment. The present envelope sheet comprises a front panel connected to a back panel along a bottom fold line, to a closing flap along a top fold line, to a left-side flap along a left-side fold line and to a right-side flat along a right-side fold line. The front panel, back panel, closing flap and both side flaps each have an upper surface and a lower surface. The back panel is adhered to the left-side and right-side flaps with a latent adhesive sandwiched therebetween. The present invention also includes a method and apparatus for automatically printing and forming an envelope from the present envelope sheet, as well as automatically stuffing the envelope while it is being formed.

Abstract: A phase-locked-loop (PLL) has a current controlled oscillator (ICO) whose gain varies with its input current. The PLL also contains a charge pump that controls the input current of the ICO and therefore the output frequency of the ICO. The charge pump has a gain that is controlled by the ICO input current in a manner which linearizes the combination of charge pump and ICO. This results in a substantially constant loop gain for a PLL.

Abstract: A siphonic flush valve for a toilet having a toilet tank and toilet bowl. The valve includes a housing supportable in the toilet tank and defines a chamber, an upleg open to the chamber and a downleg open to the upleg. The chamber includes a manually actuatable piston system slideably supported therein for forcing water in the chamber into the upleg. The flush valve also includes an adjustable check valve and a vent and reseal tube.

Abstract: A lug lid (10) which closes an open head pail (12) has lugs (31) that overlap the annular rim (19) of the pail and which are crimped thereabout to attach the lid to the pail. An annular expansion bead (38) is formed in the lid to enable the lid to expand to relieve some of the increases in internal pressure which might occur in the container. Sacrificial depressions (46) are formed in the lid (10) adjacent the expansion bead (38) with each sacrificial depression radially aligned with a lid lug (31). The sacrificial depressions selectively weaken the lid to control the formation of wrinkles (47) in the lid in response to increased pressure within the materials container, with such wrinkles being formed in radial alignment with the lugs of the lid, where the connection between the lid (10) and the pail (12) is strongest.

Abstract: An arrangement for interconnecting groups of users into collision domains in a Local Area Network such as an Ethernet comprises a plurality of repeater groups, with each repeater group being connected to a group of user stations. The arrangement also comprises an electronically reconfigurable switch matrix. The switch matrix comprises a plurality of segment lines (or other transmission media) each of which is used to form one collision domain or Ethernet segment. Switch elements under the control of a microcontroller selectively connect particular repeater groups (and the associated user groups) to particular segment lines to form Ethernet segments, each Ethernet segment being a single collision domain. Internetworking devices such as bridges and routers may also be connected to the switch matrix to interconnect particular collision domains.

Abstract: A method for calibrating topographic instruments, operating at sub-micrometer resolution levels, includes providing a calibration standard having a known one-dimensional power spectral density function. A roughness is calculated from the known one dimensional power spectral density function in relation to an atomic scale topographic dimension, .increment.z.sub.i. The roughness of the calibration standard is measured by detecting light scattering therefrom and computing an isotropic power spectral density curve over the effective spatial bandwidth of the topographic instrument being calibrated. The measured roughness is then compared against the calculated roughness to determine whether the two values of roughness coincide.

Abstract: Oil management apparatus for a refrigeration chiller includes a housing mounted to the head wall of an oil supply tank. The housing defines a series of ports and internal flow passages in communication with a valve cavity. A valve spindle disposed in the cavity is configured and positionable such that a plurality of oil flow passages within the chiller are capable of being setup in order to accommodate various chiller lubrication needs including those as they relate to both chiller operation and maintenance. The combination of an integral housing and single valve eliminates a large number of individual valves and the need to connect those valves and various chiller lubrication components, such as an oil filter and oil pressure regulator, with individual sections of difficult to fabricate piping. As a result, the likelihood of error in the setup of a chiller lubrication system is significantly reduced.

Abstract: A protective liftgate cover for covering and protecting the ground-engaging lower face of a liftgate platform includes a generally rectangular plate of a size and shape to fit over and generally complete cover the lower face of the liftgate platform. A lower flange and at least one side flange are mounted on the plate adjacent a respective lower and side edge for contacting the lower and side edges of the liftgate platform, thereby protecting those elements of the platform. At least one ground-engaging foot is mounted on the outer surface of the plate for contacting and engaging the ground surface and the plate is secured to the liftgate platform by one or more fastening devices. The liftgate cover thus provides protection for the lower face of the liftgate platform.

Abstract: A device for monitoring and modulating the admission of fresh air into a building. The device comprises a housing; a sensor associated with the housing and operable to measure airflow through the housing; and a damper including at least two damper blades. Each damper blade includes a shaft rotatably attached to the housing at least at a first shaft end. The shaft is located on the surface of the damper blade so as to divide the surface into first and second substantially equal areas.

Abstract: In a device for controlling a flow of metal from a casting vessel into a casting mould, the inflow of metal is to be controlled by means of a stopper, which may be lifted and lowered according to a preset program and/or by means of a bath-level measuring device. In order to prevent any manual operation of a control lever for the stopper, a lifting rod for the stopper is disposed in a module box together with a vertical guide and a computer-controlled electromechanical drive for the lifting rod. The module box is exchangeably fastened to the casting vessel by clamping elements. Before casting begins, a drive motor for the stopper (13) is to be connected by means of electric plug-and-socket connections to a control cabinet. From the start of casting, the stopper movement is controllable exclusively by means of the electric drive.
