    摘要： A method detects the proportion of combustible gas in a mixture of air with a measuring device which operates by both the heat-tone and heat-conductivity methods. The method permits measurement in the full concentration range with a high degree of accuracy and the lowest possible energy consumption. The measuring device is made small and light and its sensor has a long service life. The method uses one single sensor which operates at a low temperature in the heat-conductivity mode or alternatively, catalytically active at a higher temperature in the heat-tone mode. If the measurement provides a result below a reference value or within a reference value window, measurement continues in the more accurate heat-tone mode. When the gas concentration increases during measurement, in order to avoid ambiguity of the measuring signal and damage to the sensor above a load-limit value, measurement again takes place in the heat-conductivity mode by reducing the temperature of the sensor.

    摘要： An adaptor for a three point hitch of a tractor allows the adaptor to attach to the hitch bar of a trailer without the necessity of vertical or horizontal adjustment of the position of the tractor relative to the trailer. The adaptor comprises a vertical post having an upper end attached to a centre arm of the three point hitch. A pair of side arms of the adaptor attached to the lower arms of the three point hitch. A J-shaped hook member has a longer leg projecting through a slot in the post and a shorter leg which abuts against a rear face of the post in the hitching position. The hook engages around a loop attached to the trailer. A cylinder coupled to a forward end of the longer leg can actuate pivotal movement of the hook about a pin attached across the post to move the hook from the hitching position to a release position.

    摘要： Paraffin alkylation using solid, particulate catalyst is carried out by preparing an alkane-catalyst mixture in a wash zone, passing the alkane-catalyst mixture to a plug flow reactor where a minor amount of olefin is introduced to contact the alkane-catalyst mixture and react to form alkylate and the alkane-catalyst-alkylate mixture is passed through the reactor with a minimum of back mixing to restrict the reaction of alkylate with olefin, thus substantially preventing polymerization. The alkane-catalyst-alkylate mixture, substantially free of olefin is passed to a disengaging zone where the liquid is removed and the solid particulate catalyst is recovered and returned to the wash zone for recycle. The alkane is present in the reactor in sufficient molar excess to react substantially all of the olefin. Any unreacted isoalkane is recycled to the reactor with make-up isoalkane added to maintain the molar excess. The preferred catalyst is an acid washed silica treated with antimony pentafluoride and more preferably treated with alkane at low temperature, e.g. -30.degree. to -160.degree. C.

    摘要： An optical phased array transmitter/receiver includes a plurality of waveguides each including an optical fiber and a light source coupled to the fibers in the waveguides. At least one grating is coupled to the fiber of each waveguide and at least one phase shifter coupled to the fiber of at least one waveguide. The phase shifter controls a phase profile of light passing through the fiber to control a profile of a laser beam reflected at the grating. The gratings reflect light passing through the fibers outside of the optical coder to form a laser beam shaped and directed by the grating and phase shifters. Further, a detector is coupled to the waveguides that is enabled to receive light reflected off the gratings. Other embodiments are described and claimed.
