Abstract: A shock-activated shut-off valve including a housing having an upper chamber and a lower chamber separated by a flap-gate pivotally connected to the housing, the lower chamber comprising an inlet orifice, and outlet orifice and a flap-gate stop means; a weight; a shock-actuated retainer defining a weight-passable opening and a latching means comprising a receptacle arm pivotally connected to a counter-weight and a flap-gate actuator, wherein, in one position, the counter-weight maintains the receptacle arm and the flap-gate in a horizontal position and the weight rests on the retainer and wherein, in another position, upon shock-actuation, the weight disassociates from the retainer and, subject to vertical acceleration, engages the receptacle arm, exerting a force which exacts pivotal movement of the counterweight to allow release of the flap-gate from a horizontal position to a position engaging the flap-dash gate stop means, thereby closing the inlet orifice from the outlet orifice.

Abstract: By the use of two picks without weft yarn (5, 6) during the pile change for three-weft pile fabrics, the same tying off is achieved as in a pile change for four-weft pile fabric. A three-weft terry cloth consequently has a fabric appearance which resembles the fabric appearance of a four-weft terry cloth.

Abstract: The cloning and characterization of a new binding protein class, cyclophilin C (cyp C) and homologous proteins, is provided which is capable of binding to, e.g., the immunosuppressive drug cyclosporin A (CsA). The pattern of cyp C mRNA expression differs from that of cyp A mRNA expression, with cyp C being expressed in a more restricted subset of tissues, including those tissues reported to be most affected by CsA therapy. A fusion protein containing, e.g., amino acids 16-212 of cyp C has peptidyl-prolyl-isomerase activity (PPIase), and CsA inhibits this activity. Most significantly, these cyp C fusion proteins can be used as ligands for the identification of intracellular proteins which together form high affinity associations. For example, the cyp C fusion protein binds specifically to a protein of 77 Kd in the absence of CsA, while in the presence of CsA it no longer binds to this p77, but instead binds specifically to a protein 55 Kd, identified as calcineurin.

Abstract: Viable bacteria may be detected in biological samples by exposing bacterial cultures obtained from the samples to transducing particles having a known host range. Such transducing particles carry a heterologous gene capable of altering the phenotype of the bacteria in a readily detectable manner. For example, the transducing particles may carry an ice nucleation gene and the alteration of phenotype may be detected using an ice nucleation assay. By employing a panel of phage, unknown bacteria may be typed based on the pattern of reactivity observed. The method is particularly useful for detecting viable bacteria which may have been debilitated by exposure to sterilizing conditions, such as in food processing. The method is also useful for tracking a target bacteria in the ambient environment.

Abstract: A computing system, having an input/output bus for communicating data thereon, is connected to a network by a pair of network controller devices. Each of the network controller devices, in turn, connect to a corresponding one of a pair of multi-ported network repeater elements which are, in turn, connected to one another by a pair of network links. At least one workstation is connected to each of the network repeaters. One of the network controllers is initially selected as a primary data communicating path from the computing system to the network. The network controllers periodically transmit messages to one another, and if receipt of those messages by the primary network controller is noted, the selection of the primary controller will be switched to the other.

Abstract: A transmission line driver circuit for use in data communication transmitters that is capable of meeting the return loss specifications as well as the electrical interface specifications as defined by C.C.I.T.T. standards for E1/T1 transmission. The line driver circuit of the present invention maintains minimum output impedance during the entire dynamic range of the transmit signal while meeting the pulse shape template requirements. The circuit includes a predriver stage that controls the slew rate of the transmit signal within the constraints of the pulse template. This allows a subsequent output driver stage to enjoy fast slew rates, large gain and dynamic range, and very small output impedance to meet the return loss specification.

Abstract: A content-addressable memory wherein match transistors are prevented from discharging a match line by either placing transistors in series with the match transistors and only turning them on during a match sensing period, or a match sense line which is driven near the precharge voltage of the match line until the match sensing period. The match sensing line also provides charging current to recharge the match line. For some applications, a differential match line amplifier is used to detect matches and mismatches. The match sense line can be used with a CAM having a four-transistor comparator. The invention is also applicable to match lines in programmable-array logic (PAL) cells, and for either NMOS or PMOS circuits.

Abstract: A unitary syringe assembly including a diluent syringe and a jell syringe stores and enables convenient transport of isolated components required for injection. A valve is placed between the two syringes. Immediately before required injection, the valve is opened and intermixing injection and reception of the diluent and jell between the two syringes occurs to thoroughly intermix the diluent and jell. The valve aperture size is selected to provide viscous resistance by the jell until thorough mixing has occurred to provide the user with a tactile indication of sufficient mixing. Upon complete mixing, a needle is attached and injection occurs. Paired side-by-side unitary syringes are utilized with an interconnecting mixing manifold with injection occurring from one syringe only to enable higher needle injection pressure.
