20100162940, Jul 1, 2010

Filed:

Dec 30, 2008

Appl. No.:

12/346560

Inventors:

Stephen A. Hill - Brisbane CA, US
Eric R. Hill - Brisbane CA, US

International Classification:

G01N 21/81

US Classification:

116206

Abstract:

A ‘Blue Dot’ stick-on moisture indicator system that includes a stick-on transparent, polypropylene film patch with a sticky, pressure sensitive, hot melt, rubber-resin that applies on one surface, a dimensionally smaller, ‘Blue Dot’ indicator patch and a dimensionally larger, silicon treated, release (peel) liner strip to which a plurality of stick-on film patches with ‘Blue Dot’ indicator patches, are affixed to such that functionally isolates both the moisture sensitive ‘Blue Dot’ (cobalt chloride treated paper) from moisture and the surrounding sticky surface of the stick-on film from debris before the indicator is applied or deployed (adhered) onto a surface.

International Classification:

H04M 900

US Classification:

179 99A

Abstract:

A multi-link intercom system having a large number of stations selectively connected to one of eight links by respective station controllers. When a calling station goes off-hook, its station controller connects the station to the first available link during the one of four link access periods corresponding to that link. The calling station then applies appropriate signals to the link identifying the called station. These signals are decoded by a link controller for the link which generates called station address signals during its corresponding link access period. All of the link controllers generate called station address signals on the same bus, but the signals are time multiplexed to occur during a portion of each link access period corresponding to each link. The station controller for the called station recognizes its address and connects its station to the link corresponding to the portion of the link access period in which the station address was received. Two-way communication between the calling and called station is then effected.

Inventors:

Stephen M. Hill - Buckley WA, US

International Classification:

F16B 13/12
F16B 13/06
F16B 35/00
F16B 39/02

Abstract:

In implementations of a pressure lock retention fastener, the fastener assembly includes an insert sized for insertion into a fastener hole in a first panel. The fastener assembly has a threaded collet sized to slide in the insert and has expandable flanges that extend below the insert. The expandable flanges are sized for insertion into an aligned hole in a second panel. The fastener assembly also includes a screw installable through the insert to engage the threaded collet. The screw exerts a force that pushes the expandable flanges outward as screw rotation drives the screw into the threaded collet, and ridge locks of the expandable flanges seat up against the second panel effective to fasten the panels together. In implementations, a plate is installable between the panels with slotted holes having anti-rotation tabs that prevent a fastener assembly from spinning in the panel holes.
