Abstract: A low-cost safety valve for gas lines and similar supply lines that can be remotely activated via a secure wireless link employing a low leakage sealing mechanism that is compatible with low energy actuators to for extended battery life. A miniaturized controller and wireless electronics assembly provides the control mechanism for actuating the valve, as well as reporting data regarding the valve status to wireless interrogators or external networks via an ad hoc wireless network. A variety of simple magnetic valve operating mechanisms can be implemented with the miniaturized electronic control circuits and the valve body. Such control actuation mechanisms enable automatic resetting or manual resetting valves. The gas line shut off valve can provide important safety benefits at an affordable price. An RFID transceiver may be included to enable low-power operation and communications using RFID technologies as well as an automatic antenna tuning capability to maximize radio range.

Abstract: An apparatus is set forth including spaced, vertical support members releasably mounted to a top horizontal frame member. Side vertical frame members include stabilizer legs pivotally mounted thereto to secure the organization in a vertical orientation for support of venetian blinds thereon. The top frame member includes a series of orthogonally and fixedly mounted pegs directed forwardly of the frame member to secure a venetian blind arrangement thereon. Plate bars are scissored and secured between the vertical frame members to enable collapsing of the organization when the top frame member is removed therefrom.

Abstract: a propulsion and steering apparatus generally for a boat having a unitized construction comprising an engine, propeller, rudder and protective cage for the propeller, all mounted on a rotatable pylon adapted to be secured to the transom or other portions of the boat. A rudder is attached to the pylon and projects into the water to facilitate steering of the boat if the engine should die or be at idle speed. An ice break can be substituted for the rudder for use of the vehicle on snow and frozen water such as for ice fishing and rescue work. If desired, the apparatus can be mounted forwardly of the transom on transversely extending beams in the boat to provide a large open area that will be kept available for fishermen and equipment in the rear of the boat. The entire propulsion means is adaptable to be hinged to the mounting so it may be laid down to present a low profile for moving under bridges, storing in garages and while being transported on the highways.

Abstract: Apparatus adapted to be mounted on a vehicle frame for the purpose of increasing traction comprises an L-shaped framework, a first shaft rotatably mounted on the upper portion of the framework, a second shaft rotatably mounted on the framework and disposed below and spaced from the first shaft, spaced third, fourth and fifth shafts rotatably mounted on the framework and extending outwardly from the second shaft, a power source operable to rotate the first shaft, means interconnecting the first and second shafts to impart rotation to the second shaft, multiple wheels fixed in coaxial relationship respectively on the second, third, fourth and fifth shafts, track means mounted on the peripheries of the wheels, brake means associated with the first shaft and operable to fix the framework to the vehicle, and a second brake means operable to fix the framework to the second shaft.

Abstract: A radiation detection device comprises a radiation source and a plurality of detectors and crystals positioned thereabout to simultaneously detect certain known wavelengths. Each detector emits a signal representative of the intensity of the detected wavelength and a summing means adds the signal intensities together to give a unitary output signal. This summed output signal can then be used as a material sorter through a direct read out or can go into a function circuit which compensates an X-ray thickness gauge for changes in composition. In the latter situation, a function circuit output can be fed forward to control the machinery responsible for producing the thickness obtained.
