Abstract: An apparatus for flow detection, measurement and control and method for use of same in a piping and/or fire sprinkler system. The apparatus combines a flow sensor for creating an electrical output proportional to flow through therethrough with a bypass means for allowing flow through an alternate flow path where a primary flow path is insufficient to supply the demand. The apparatus includes a moving orifice plate, which is displaced by flow through the sensor and creates an electronic output by the interaction of a moving magnet moving in tandem with the orifice plate with a normally closed Reed switch on an exterior surface of the sensor, which is opened when the magnet is displaced into sufficiently close proximity to the Reed switch. The apparatus can also be adapted to serve as a double check valve. A moving check is added with a sealing means thereon for providing one check, and sealing means on the orifice plate are provided to serve as a second check.

Abstract: An apparatus and method for a flow-based fire alarm. A bypass system is provided to allow sufficient water flow where a pressure drop, particularly in a residential or multi-purpose piping system such as a water softener is encountered, by providing an alternate, lower pressure flow path allowing additional flow when the pressure drop through the system becomes too great. Flow detection means are also provided with minimal pressure drop to insure that flow for fire protection need is not unduly restricted. The flow detection means includes either a differential pressure switch coupled to an orifice plate or a moving orifice plate having thereon a magnet, which communicates with a Reed switch in proportion to the flow therethrough. An integral system incorporating all of the elements discussed provides multiple levels of security for a fire protection system for use in a residence or other structure.

Abstract: A method is disclosed for resizing multi-dimensionally rendered graphical images. A first step in the method divides a graphical image into a plurality of predefined resizable and non-resizable sections. A second step in the method further divides the resizable sections into a plurality of stretch areas. A third step in the method divides each stretch area into a cell matrix. A fourth step in the method resizes the graphical image by duplicating or removing a row or column of matrix cells in one or more of the stretch areas.

Abstract: Recombinant mycobacterial vaccine vehicles capable of expressing DNA of interest which encodes at least one protein antigen for at least one pathogen against which an immune response is desired and which can be incorporated into the mycobacteria or stably integrated into the mycobacterial genome. The vaccine vehicles are useful for administration to mammalian hosts for purposes of immunization. A recombinant vector which replicates in E. coli but not in mycobacteria is also disclosed. The recombinant vector includes 1) a mycobacterial gene or portions thereof, necessary for recombination with homologous sequences in the genome of mycobacteria transformed with the recombinant plasmid; 2) all or a portion of a gene which encodes a polypeptide or protein whose expression is desired in mycobacteria transformed with the recombinant plasmid; 3) DNA sequences necessary for replication and selection in E. coli; and 4) DNA sequences necessary for selection in mycobacteria (e.g., drug resistance).

Abstract: A receiver implemented decoding of selectively processing channel state metrics to minimize power consumption and reduce computational complexity. The method involves disabling a channel state (signal strength) computation algorithm during decoding of information received on the control channel of a trunked communication system during static conditions. Because the bulk of a radio's power is consumed while in standby mode listening to data information transmitted over a control channel, and because control channel information is typically received while in a good channel quality environment, significant power consumption reduction is realized by disabling the channel state computation algorithm. When a poor quality channel condition is detected, such as may occur when a message error rate (MER) is above the MER quality threshold set for that radio, the radio will enable the channel state computation algorithm.

Abstract: Eukaryotic RNA polymerase II holoenzymes that contain RNA polymerase II and one or more regulatory proteins are described. These holoenzymes selectively initiate transcription in vitro when supplemented with general transcription factors. The regulatory proteins act positively and negatively to regulate transcription initiation, at least in part, via functional interactions with RNA polymerase II.

Abstract: A roller bracket apparatus includes a roller assembly which includes a carriage portion and a link portion projecting from the carriage portion. A push/pull assembly is provided, and a pivot assembly is connected between the link portion of the roller assembly and the push/pull assembly. The carriage portion includes a wheel-support portion and a plurality of axle/wheel assemblies supported by the wheel-support portion. Each of the axle/wheel assemblies includes an axle and a roller wheel connected to the axle. The link portion extends from the carriage portion at an acute angle with respect to a plane common to the top surface of the carriage portion. In an alternatively preferred embodiment of the invention, the push/pull assembly includes a first side portion connected to the article being moved (e.g. an overhead door panel) and an integrated gusset plate portion orthogonally connected between the first side portion and the pivot assembly.

A base defines a longitudinal axis along which the electrical cable is disposed. A plurality of terminals are mounted on the base and are spaced laterally of the axis for terminating the conductor wires. A cover is pivotally mounted on the base and includes a spreader structure for engaging and spreading the conductor wires automatically in response to mounting the cover on the base.

Abstract: A printer blank for a computer system printer is disclosed. The blank has a contiguous pressure adhesive backed label section and may also have a larger plain paper section separated from the label section by a perforation line. The label section is comprised of a plurality of adhesive backed labels and a backing sheet, including a main label portion and at least one smaller auxiliary label. A preferred blank comprises a plurality of auxiliary labels. In use, at least one, but preferably not all, of the auxiliary labels on such a preferred blank are simultaneously removed from the backing sheet with the main label portion. Any auxiliary label(s) simultaneously removed with the main label but not printed upon are readily separated from the main label.

Abstract: An improved surface-mount electrical wire connector includes a connector housing and electrical contacts. The housing supports the electrical contacts and includes an upper surface with openings to receive the stripped ends of electrical wire. The upper surface includes an enhanced bearing surface established between a pair of openings by selectively chamfering the perimeter of the openings. This enhanced surface accommodates a suction-cup head on conventional pick-and-place assembly equipment. The electrical contacts include an upper section for receiving and retaining a wire and a lower section, extending through a lower surface of the housing, for solderably affixing the connector to a printed circuit board. The lower section of the contacts preferably include two, parallel, spaced apart members which provide four exposed surfaces to receive and retain solder.

Abstract: An RNA polymerase II holoenzyme that contains, in addition to RNA polymerase, a subset of the general transcription factors together with nine SRB proteins is described. This holoenzyme will selectively initiate transcription in vitro when supplemented with TATA-binding protein (TBP) and factor a (TFIIE). The SRB proteins act positively and negatively to regulate transcription initiation, at least in part, via functional interactions with RNA polymerase II.
