Abstract: A pipe support for supporting pipes on a building surface comprising a strut vertically movable on supporting rods for changing the vertical spacing of a pipe above the building surface and spring clips connecting the strut to the rods, the spring clips having a locking position securing the strut in a fixed position and a release position that permits the strut to move along the rods.

Abstract: A pipe support for supporting gas lines and the like on a roof comprising a generally unitary member formed from a rubber-like material resistant to water and sunlight, the support including a triangular body formed by a base, converging legs and a connecting portion at the apex of the body, and clamping arms that extend from the connecting portion to form a pipe receiving and supporting chambers into which a pipe can be engaged by pressing the legs together to spread the arms apart, the pipe being clamped in the chamber by releasing the legs so that the arms close on the pipe.

Abstract: A lamp with improved safety features, to avoid fire and burn hazards, includes an electrical circuit having a thermostat connected in series with the bulb of the lamp. The thermostat is mounted in close proximity to the lamp's bulb and, upon the ambient air temperature in the vicinity of the thermostat reaching a predetermined temperature, the thermostat effectively opens the electrical circuit, shutting the lamp off. Once power is turned off for a period of time, the thermostat resets and the lamp may be operated again. A protective guard is positioned over at least a portion of the bulb of the lamp to prevent accidental burning. Alternatively, the electrical circuit further includes a detector for sensing an object being placed within the lamp shade and generating a signal in response thereto. The detector is electrically connected to a switching device which terminates power to the lamp in response to the detector signal.

Abstract: A method and apparatus for detecting flaws in web material such as fabric comprises an array of optical sensors arranged in closely spaced relationship into at least one row spanning the web to be inspected. A light source is mounted in spaced parallel relationship relative to the sensor array and the web passes between the light source and the sensors. Each sensor produces a voltage signal that is proportional to intensity of light falling thereon and, therefore, to the amount of light transmitted by the portion of the web passing adjacent the sensor. The sensors are connected to a microprocessor that is programmed to compare their signals to standards representing signals produced by flawless fabric. A predetermined number of comparison results are combined and transformed into a single representative value that is compared with a preselected threshold value. If the representative value exceeds the threshold, a signal indicative of a flaw is produced by the microprocessor.
