Abstract: A hollow tube (138) attached to a container (12) of fluid is provided with an en d cap (144) in which is formed a fluid discharge opening (154). A slide valve (108) on the exterior of the tube is bias ed into a closed position, percluding fluid transfer until the discharge opening is inside a receiving vessel. An air vent tube (158) withi n the conduit admits air into the container. Fluid filling a receiving container closes the air vent tube when the receiving vessel is filled. The air vent tube includes one or more capillary sections (162, 166) of reduced inner diameter relative that of the air vent tube. A seal (186) is provided for closing the air vent tube when the slide valve is in its closed position. A relief passageway ( 192) with a one-way valve (194) permits fluid to drain from the vent tube following each fluid transfer.

Abstract: A Global Positioning System (GPS) commercial receiver is provided with a digital processor that can utilize to advantage P-code modulated L1 and L2 satellite signals which have been modulated with an unknown security code. Integration of the L1 and L2 signals, after demodulation by locally generated carrier and P-code signals, is repetitively accomplished over a duration that is estimated to be the period of the modulation code. The C/A-code L1 signal, which is not modulated with the unknown security code, is also used in locking the locally generated carrier and P-code generators in phase with the received L1 and L2 satellite signals. A interpolative technique is used for adjusting the phase of the locally generated carriers and code in increments much smaller than the period clock sources. Those locked phases can then be utilized to determine position, distance, time, etc., as is done in GPS receivers not utilizing the anti-spoofed signals but with increased accuracy and resolution. A novel structure of the GPS receiver radio frequency and intermediate frequency sections, having a specific combination of demodulating frequencies, is also disclosed.

Title: Threshold time dependent logic system for assigning elevator cars
Inventor: BAHJAT ZUHAIR S
IPC: B66B1/18
Filed: 1992-02-25
Granted: 1996-01-02
Abstract: The present invention is directed to notifying a user of an arriving elevator car in response to a hall call registered by the user, wherein notification occurs a threshold time value before elevator car arrival. In the preferred embodiment, an elevator car is assigned to a floor in response to a hall call. The amount of time required for the assigned elevator car to arrive at the floor is determined and compared with the threshold time value. If the arrival time is greater than the threshold time value, the system reexamines assignment, possibly reassigning a different elevator car to respond to the hall call. The arrival time of the assigned (or newly assigned) elevator car is again determined, and this process continues until the arrival time is less than or equal to the threshold time value. When the arrival time is less than or equal to the threshold time value, the hall lantern at the door of the assigned elevator car is energized, e.g., illuminated and/or sounded. Additionally, the hall call is removed from further consideration regarding reassignment to another elevator car, thereby fixing the elevator car assignment In the preferred embodiment the threshold time value can be a constant value determined by, e.g., the building manager. Alternatively, the threshold time value can be variable by the system, e.g., based on the intensity of the traffic as measured by user waiting time or user boarding and/or deboarding rates, whether actual or predicted.

Abstract: The use of the superoxide dismutase (SOD; EC 1.15.1.1) gene system as a target for the detection and differentiation of pathogenic and non-pathogenic organisms including bacteria, fungi and protozoans is described. More particularly, there are described oligonucleotides derived from the SOD gene family which oligonucleotides are capable of hybridizing to a single-stranded nucleic acid sequence (target sequence) which is obtainable by amplifying and maturing a part of a gene coding for a superoxide dismutase (SOD) using a polymerase chain reaction (PCR) and a pair of primers, the first primer containing the sequence 5'-AGC TTC ACC ACA GCA AGC ACC A-3' (Seq. Id. No. 1; Z205) as priming sequence and the second primer containing the sequence 5'-TCG      G(T)CC CAG TTC ACG ACG(A,T) TTC CA-3' (Seq. Id. No. 2; Z212) as priming sequence. These oligonucleotides in the form of primers and probes are useful for the amplification and detection of target sequences derived from SOD genes, especially, from SOD genes of pathogenic and non-pathogenic organisms including bacteria (e.g. mycobacteria), fungi and protozoans.

Abstract: The disclosure herein describes a needle assembly for use with a syringe which includes a needle device having a holder and a needle, and a needle guard which is defined by a hollow cylindrical sheath that partially surrounds the needle; the guard has a first end mounted to the needle holder and an opposite closed end in proximity to the needle pointed end. Elongated slots and pivot pins cooperate to anchor the needle guard to the holder. In one embodiment, the slots are provided on the needle guard and the pins on the holder while, in a~ second embodiment, the slots are provided on the holder and the pins on the guard. This cooperating arrangement of the slot and pins allows the sheath to be pivoted back at substantially 180° relative to its needle surrounding initial position thus removing the presence of the sheath as much as possible from the needle puncturing operation.
