摘要:
A method of uniformly breaking glass fibers in a bundle of fibers in which the apex of a cone is inserted into the end of the bundle. The fibers in the bundle are distributed in a single plane about the surface of the cone with the free ends of the fibers extending beyond the base of the cone. A sleeve on the bundle is shifted forwardly toward the base of the cone to firmly grip the fibers therebetween. The outer surfaces of the fibers are then scratched and a compressive force is exerted to the free end of the fiber bundle to cause the fibers to bend and break at the base of the cone.

A vehicle heater adapted to be plugged into a conventional car cigarette lighter. The vehicle heater includes an adapter for plugging the invention into a cigarette lighter, a switch for turning the heater on, a clock for setting a timer to turn the heater on at certain times and indicator lights for indicating when the unit is turned on when the battery power is low and when the air temperature is too high. The heater contains conventional heating elements and can be used in connection with any car cigarette lighter socket.
摘要:
A radio frequency modulator/demodulator (modem) and method for receiving and transmitting data over a radio frequency data link. The modem has a transmitting section which includes a modulator which modulates a radio frequency signal in response to data provided by, for example, an associated processor. The transmitting section further includes a watchdog or enable circuit which monitors a request-to-send signal produced by the associated processor, with the request-to-send signal being present when the processor is generating data to be transmitted over the data link. The enable circuit will disable the modulator should a transmission exceed a maximum predetermined time period, thereby preventing the associated processor from monopolizing the data link in the event of a processor failure.

A contact assembly for installation in an electrical connector, provides effective electromagnetic filtering in a simple, compact, and rugged construction that facilitates in-field replacement of a damaged contact assembly. The contact assembly includes a signal conductor, a diode for diverting high voltages on the signal conductor to ground, and a "pi" filter for filtering out unwanted frequencies. The "pi" filter includes a ferrite bead inductor coupled to the signal conductor and a first capacitor coupling a location of the signal conductor on a first side of the inductor to ground. The other capacitor of the "pi" filter is formed by the capacitance of the diode, with the diode connected to a signal conductor location on a second side of the inductor, and with the capacitance of the diode similar or equal to that of the first capacitor. The diode is mounted in a notch of the signal conductor, the ferrite bead inductor lies immediately forward of the notch, and the first capacitor lies immediately forward of the ferrite bead. A ground conductor has a sleeve portion that immediately surrounds both the first capacitor and the ferrite bead, and has a finger contacting the diode. Solder holds the finger of the ground conductor in place both mechanically and electrically. A quantity of epoxy fills the remaining notch area and forms the middle of the assembly with a cylindrical periphery to facilitate insertion and removal from a long narrow hole in the connector.
摘要:
A contact retention clip is provided with a B-stage epoxy resin coating. The clip is installed in the contact cavity of a plastic body under heat and pressure to cause the coating to form its final resin. The resin becomes impregnated into the wall of the cavity to seal micro cracks in the wall which otherwise may lead to voltage breakdowns.
摘要:
An electrical connector in which conductive rubber rods are mounted in a nonconductive substrate. The rods extend above and below the upper and lower surfaces, respectively, of the substrate for electrically interconnecting conductive traces on a pair of electronic components, such as a display panel and logic circuit used in a digital wrist watch. A method for making the connect is disclosed.
摘要:
The present disclosure is directed to a device for displaying the estimated drying time of an applied layer of a coating composition that is based on the input of several process variables that can include temperature, humidity, film build, air velocity, altitude, the type of coating composition or a combination thereof. The disclosed device provides an input for one or more of the process variables, a network or algorithm for computing the estimated drying time based on the input process variables, and an output device for displaying the estimated drying time.
摘要:
A process for producing building materials, such as asphalt, cement, concrete, mortar, or plaster board from liquid paint sludge containing water and paint solids produced from overspray in commercial paint booth operations. The preferred embodiment comprises adding the liquid paint sludge as the hydrating agent directly to the building material mix.
