摘要:
Fire sprinkler system comprising a network of CPVC pipe lengths in which at least some of the pipe lengths are interconnected with mechanical devices having resilient sealing members that are chemically compatible with the CPVC composition. Repairs and system modifications can be made without the use of solvent cement. In-line joints are formed with a coupling device including a pair of arcuate coupling segments having a first end, a second end, and an interior concave surface extending between the first end and the second end. A longitudinal channel extends along the concave surface. At least one mechanical fastener is operative to detachably connect the pair of coupling segments. A resilient annular seal is located within the longitudinal channel of each segment. A branching device connects a branch pipe to a main pipe through an orifice in the main pipe utilizing a saddle-like sealing member. The pipe assemblies are able to pass UL testing protocols for wet fire sprinkler systems.

The invention provides assay methods and reagents useful for evaluating the level of enzyme activities within living cells. Enzyme activity levels within living cells, such as Serine proteases, can be key determinates in assessing; 1) the presence of tumor (cancer) cells, 2) the predictive efficacy of a chemotherapeutic treatment regimen using a particular therapeutic agent or process, 4) the probability of graft rejection or acceptance, and 5) the disease state status of a cell. The identification of the up or down regulation relationships of serine proteases within living cell systems, provides a rapid, yet finely tuned mechanism for predicting the current and future physiological state of these cell populations.

A method and apparatus is provided for providing a fine delay by switching on a capacitor delay. A coarse delay and/or a fine delay are implemented upon a reference signal based upon a phase shift between the reference signal and a feedback signal. A fine delay is implemented upon the reference signal based upon a phase shift between the reference signal and a feedback signal. Providing the fine delay includes switching on a capacitive delay. A synchronized output signal is generated based upon the fine delay.

A surgical device includes a structural portion which is formed of a first element, such as titanium, which has an outer surface and an inner core. A second element, such as oxygen, is combined with the first element without creating a shear plane, to create a concentration of the second element in the first element which varies from the outer surface to the inner core. In an associated method, the second element is driven into the first element under other than ambient conditions to develop a concentration gradient of the second element between the outer surface and the inner core of the first element.
摘要:
A system for anonymously initiating communication between system-connected communications devices is provided wherein the initiation of communication results from comparison and priority matching of profile information shared between the devices. The system in one aspect comprises at least two communications devices connected to the system, the communications devices having at least a microprocessor, a data-input mechanism, a display screen, a wireless local-area-network protocol application enhanced with short-wave radio communication capability installed per instance to each of the devices, and a profile comparison and matching application installed per instance to each of the devices. When any two of the devices come into short-wave radio range of each other, the devices activated, a wireless local-area-network is established and the in-range devices swap profiles, which are compared to profiles held locally on each device such that a profile match registering on at least one device enables the device matching the profile to signal the sending device of the matched profile in order to request communication between the devices.

A stud wall framing construction comprises a lower track; an upper track aligned with and vertically spaced from the lower track; and a plurality of vertically aligned studs positioned between the lower and upper tracks. The lower and upper end portions of the studs are positioned within the lower and upper tracks, respectively. Each of the lower and upper tracks includes a channel with opposed track sidewalls and a track base wall. The track sidewalls have a plurality of inwardly projecting track protrusions formed from the sidewalls. Each of the track protrusions on one of the sidewalls is paired with another track protrusion disposed across the opposite sidewall. The lower and upper end portions of the studs has opposed stud sidewalls and plurality of inwardly projecting stud protrusions formed from the stud sidewalls. Each of the stud protrusions on one of the stud sidewalls is paired with another stud protrusion disposed across the opposite stud sidewall. The track and stud protrusions are adapted such that each of the pair track protrusions nest into a respective pair of stud protrusions, thereby locking the studs in the tracks.

An allergy testing system, for testing a patient for a plurality of allergies at substantially the same time, comprises a housing containing a plurality of packages or capsules containing an allergen and a needle, the needles being spaced apart from each other. The needles preferably carry the respective allergens on their tips. The housing is placed against the skin of a patient and an actuator is operated to engage the packages to move the needles to pierce or prick the skin of the patient, thereby applying the respective allergens to the pierced or pricked skin of the patient.

A mountable enclosure can include a base and a door pivotally connected along a vertical axis. The base and door can include electronic component mounting areas, horizontal cable management areas, and vertical cable management areas. A mounting system can include at least one enclosure and at least one bracket, the bracket having a rigid body with first, second, and third parallel surfaces wherein the first and third surfaces are on one plane and the second surface is on a different plane. The bracket can be fastened to the wall and the enclosure can be fastened to the bracket and the wall. Multiple enclosures can be installed in vertical alignment through a method that can require only one installer and the leveling of only the first bracket wherein notches in subsequent brackets are mated with pegs extending from the base of previously installed enclosures.
