  • Patent number: 5084171
    Abstract: An oil recovery mop has a floating carriage, a handle, and a number of oil-absorbing pads or squares suspended from the carriage. The carriage has a pair of tubular pontoons that support a crossbar at a clearance over the surface of the water, and the pads are removably attached to spring clips on the crossbar. When the oil mop is pushed out, one side of each pad faces the surface to absorb spilled oil. When the oil mop is pulled in, the pads reverse themselves and the other side faces down to absorb oil.

  • Patent number: 4222840
    Abstract: A readily manufacturable heated solid electrolyte oxygen sensor. The sensor includes a generally planar heater supported on a tubular reference electrode terminal in desired position normal to the longitudinal axis of said terminal and parallel to a generally planar solid electrolyte member within a cylindrical housing. The heater and terminal form a subassembly readily assemblable in concentric relationship with the planar solid electrolyte member and the cylindrical housing.

  • Patent number: 4178222
    Abstract: A readily manufacturable heated solid electrolyte oxygen sensor. The sensor includes an elongated heater supported on a tubular reference electrode terminal in desired position relative to a solid electrolyte member within a cylindrical housing. The heater and terminal form a mutually electrically isolated subassembly in which the heater is in predetermined disposition with respect to the solid electrolyte member. An elongated heater is disposed within one or more ceramic sleeves that are in turn disposed within the electrode terminal tube. The heater, sleeves, and the terminal tube are vitreously bonded together to form a subassembly.

  • Patent number: 4169778
    Abstract: A readily manufacturable heated solid electrolyte oxygen sensor having an elongated heater supported in subassembly with a tubular terminal for a reference electrode of the sensor. The heater is coaxial with the electrode terminal for predetermined disposition with respect to the sensor solid electrolyte member. The heater includes a rod coaxially in a ceramic tube and a resistance heating coil and crimped outer connector around the ceramic tube. Fused glass, directly bonded to the ceramic tube, supports the heater in the electrode terminal.

  • Patent number: 3962692
    Abstract: A silicon solid state temperature responsive switching device having a thermally dependent P-N junction. The thermally dependent P-N junction is at the interface of a thermally invertible region and a non-invertible region. The thermally invertible region is doped with both P-type and N-type impurities. The P-type impurities have a concentration which is at least about 10 times the concentration of the N-type impurities. The P-type impurities also have an activation energy which is at least about three times the activation energy of the N-type impurities. Below a predetermined temperature, the doping effect of the N-type impurities predominates, and the invertible region is N-type. However, above the predetermined temperature, the doping effect of the P-type impurities predominates. A device insensitive to voltage source polarity is formed by sandwiching the thermally invertible region between two non-invertible regions.
