Abstract: ABSTRACT       For the measurement of the transverse dimensions of a hole (50) in a well, one moves a sonde (52) on which is mounted an electro-acoustic transducer (42) in an offcentered position in relation to the axis (65) of the sonde.  This transducer has two opposite active faces (60,61) so as to simultaneously transmit acoustic pulses in diametrically opposite directions from the sonde (52).  When the sonde is centered in the hole, the transducer picks up the echos retransmitted by the wall (50) of the hole in the two directions at different times.  A recording is made of these times and preferably also of an indication of the amplitude of each of these echos to obtain both a diameter measurement and an indication of the condition of the hole surface (50).  Several transducers (42) are provided, superposed and oriented along diameters distributed around the axis of the sonde.          (Figure 3).

Abstract: ABSTRACT OF THE DISCLOSURE             A process for comminuting a porous or fluid-permeable hydrocarbonaceous solid, such as coal, containing an admixture of mineral matter and hydrocarbonaceous matter, into a shattered product is disclosed. In this process, the hydrocarbonaceous solid is comminuted to convert the hydrocarbonaceous matter in the coal into discrete particles having a mean volumetric diameter of less than about 5 microns without substantially altering the size of the mineral matter originally present in the coal.  As a result of this comminution, the hydrocarbonaceous particles can be fractionated from the mineral particles to provide a hydrocarbon fraction having a lesser concentration of minerals than in the original uncomminuted material and a mineral fraction having a higher concentration of minerals than in the original uncomminuted material.  A preferred method for comminuting the porous or fluid-permeable hydrocarbonaceous solid, i.e. coal, is to first form a slurry of coal and a fluid such as water.  This slurry is then heated and pressurized to temperatures and pressures in excess of the critical temperature and pressure of the fluid.  The resultant supercritically heated and pressurized slurry is then passed to an expansion zone maintained at a lower pressure, preferably about ambient pressure, to effect comminution or shattering of the solid by the rapid expansion or explosion of the fluid forced into the coal during the heating and pressurization of the slurry.

Abstract: ABSTRACT OF THE DISCLOSURE A method of making pneumatic tires substantially reduces or eliminates sidewall indentations in the inflated tire.  An overlapping splice is made between the ends of each layer of ply fabric to form the generally annular shape of the ply layer.  A portion of one end of the ply layer is removed from the area in which the beads are placed to form an abutting splice in this area.  The single layer of ply fabric beneath the beads prevents undertensioning of the ply cords in the reinforced overlapped layer which otherwise would result in sidewall indentations.

Abstract: ABSTRACT     The operation of gas turbines in combined cycle or cogeneration plants utilizing circulating fluidized beds is improved by increasing the temperature of the air supplied them.  The temperature of bed solids circulating through an external heat exchanger is raised by combusting fuel in a combustion-augmenting zone through which the circulating solids pass.  The gaseous products of combustion from that zone are introduced into the fluidized bed combustor.  Thus the fluidized bed combustor operates at temperatures affording optimum sulfur removal by sulfur absorbing materials, the combustion-augmenting zone operates at an appreciably higher temperature to provide increased heat transfer to the compressed air for the gas turbine, and the off gases from the combustion-augmenting zone, which may be high in sulfur, are cooled in the combustor so as to bring about their desulfurization therein.  Suitable apparatus is provided.

Abstract: Abstract Elevator Governor A flywheel or disc rotates around a circular stationary surface, for example, a shaft, the disc is configured relative to the stationary surface so as to define the tapered area or gap at diametrically opposite positions.  Two flyweights that are mounted on the disc and mechanically interconnected pivot on the disc radially outward as the disc speed increases.          A pair of rollers are located in the space between the disc and the stationary surface, and, as the weights move radially outward, are progressively forced into the tapered area or gap, eventually contacting the stationary surface where they are wedged in the gap, abruptly stopping the rotation of the disc.  The counterweights' center of masses and the pivot points are such that the centrifugal force of one weight is slightly greater than the other.  An overspeed switch is operated by the weights at a certain speed.

Abstract: ABSTRACT     A heat cooking appliance which utilizes a Roberval mechanism for effecting changes in the frequency of vibration of a turntable (8) with varying weights of the food thereon.  The vibration is transmitted to outside of the heating chamber by use of a magnetic field to produce an electric pulse signal outside the heating chamber.  In order to positively extract this magnetically detected electric pulse signal, a yoke (24) is used in a magnetic circuit and a detector coil (10) is provided near the magnet by raising the heating chamber bottom plate, thereby strengthening the magnetic coupling.  Further, for removal of electric wave noise, etc., a filter circuit (27) is provided to ensure exact extraction of the electric pulse signal corresponding to the vibration of the turntable.  Then for preventing influence of other magnetism producing equipment on the electric signal, either the vibration measurement is taken while such equipment is shut down or a magnetic shielding means is provided.  The weight of the food is calculated from the detected frequency of vibration of the turntable and in correspondence with the detected weight, the heating time, output and mode are controlled.  The cooking appliance is particularly useful in promoting ease of operation thereof and cooking with very fine adjustments.
