  • Patent number: 4141592
    Abstract: A hard compact material, such as rock, is broken by maintaining a column of relatively incompressible fluid, such as water, extending from outside into at least one hole which has been pre-drilled in the material to be broken. A shock wave is generated in the column outside the hole and is transmitted through the column into the hole. Due to the energy of the propagated shock wave, cracks are initiated and driven to a free surface of the material to break same. Breakage by the effect of the shock wave may be facilitated by means of an explosive. The explosive is delivered into the hole prior to the admission of fluid thereinto and is initiated by means of the transmitted shock wave.

  • Patent number: 4141795
    Abstract: In a dry type method and apparatus for quenching coke wherein hot coke charged in a coke quenching installation is cooled by circulating cooling gas in the installation through a closed circulating system including a blower and a heat exchanger, the composition of the cooling gas is analyzed and compared with a reference gas composition and air or nitrogen gas is supplemented to the closed circulating system in accordance with the result of comparison. A portion of the circulating gas is discharged to the atmosphere when air or nitrogen gas is supplemented. Air is supplemented on the high temperature discharge side of the circulating cooling gas while nitrogen gas is supplemented on the low temperature inlet side. The cooling gas is discharged to the atmosphere before the supplementation of the nitrogen gas.

  • Patent number: 4141529
    Abstract: A flat body portion of a holder for bunched bananas is suitable for application of a label and is suspended by an upper hook. Flexible arms extend downward from the body portion and each carries a barb or a cross arm at its extremity. In the case of a cross arm, in the unloaded condition, it hangs obliquely to facilitate insertion into a banana bunch. After insertion of the arms into the banana bunch, the arms are bent, so that the cross arms approach a horizontal position and support several bananas of the bunch, distributing the support, to avoid dropping the bunch by the breaking off of a single banana.

  • Patent number: 4142187
    Abstract: An electrical or supersonic wave having a predetermined frequency is emitted as a monitor wave from an emitting device into a zone to be monitored. When a moving object having an inherent velocity range intrudes into the zone, a reflected wave of the monitor wave from the moving object is received by a receiver and an alarm signal is issued when the frequency deviation of the reflected wave relative to the frequency of the emitted monitor wave is within the frequency range corresponding to the velocity range. The alarm device has a circuit for producing a first alarm responsive to the alarm signal, a circuit for changing the frequency of the monitor wave when the first alarm is issued, and a circuit for producing a second alarm when a further alarm signal is obtained from the monitor wave with changed frequency within a predetermined time after change of the monitor wave frequency.

  • Patent number: 4139883
    Abstract: A pivot support element is fixed in position to extend essentially vertically, and carries a horizontally projecting pivot pin. The movable pivotable member on which the weight is suspended is pivoted and connected to the pin by means of a plate-like pivot rod secured laterally to the pivotable member, so that the pivot pin will form the pivot axis for the plate-like element. The pivot pin additionally has fixedly attached thereto a link element, such as a short plate-like member to which a balance rod is pivotally attached which is connected with an intervening spring, typically a compression spring, to the weight-supporting member. Two plate-like pivot rods may be used, one on either side of the support member to provide for balanced attachment. The entire assembly is readily encapsulated in shell-like housing halves, to be essentially dust and contamination-proof, with minimum handling in assembly, or for cleaning and maintenance.

  • Patent number: 4139847
    Abstract: Ground clutter is automatically eliminated from echo signals in a weather pulse radar system to provide signals having an amplitude corresponding to the average intensity of the weather echo over a number of pulses. The reflected waves received in the receiver are linear-detected to provide echo signals. Each one of successive echo signals is compared with another later one which is apart from the each one echo signal by a predetermined time period during which fluctuation of weather target becomes independent, to derive an AC component signal corresponding to the fluctuation. The variance of the amplitude of the derived signal is proportional to the mean power of the weather echo. Thus, the ground clutter and the DC component of the weather echo are eliminated. The AC component signals are unipolarized and, thereafter, averaged. The averaged signals have an amplitude corresponding to the average intensity of the weather echo.
