Patent CA-1122161-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         A child-resistant, safety closure for a container having a dispensing end including a threaded neck portion onto which the closure is adapted to be be threadably assembled.          The closure includes an interiorly threaded sidewall having a flexible and resiliently distensible distal end portion provided with at least one interlocking member on its interior surface adapted to automatically interlockingly engage at least one complementary interlocking member on the dispensing end of the container when the closure is in either a fully closed or in at least one additional, partially removed position on the container neck portion.  Removal of the closure requires manual compression of the flexible distal end of the sidewall, applied at locations straddling the interlocking members, coupled with concurrent retrogressive movement of the closure which ordinarily must be repeated at each interlocking position of the closure, and, therefore, requires both manual dexterity and knowledgeable intent beyond the capability of young children or other persons of comparable capabilities.  Moreover, as  a further safety factor, the interlocking members are inaccessibly and unobservably secluded within the interior confines of the closure when it is interlocked on the container.          The safety closure especially features a frictional, fluid-tight seal, such as plug seal or bead seal, between the safety closure and the neck portion of the container which inter-cooperates with the aforementioned safety features to prevent leakage of the container's contents even though the closure is partially removed from its fully closed position, or which is operative to prevent leakage of the container's contents at and between both the fully closed and the succeeding partially re-moved interlocking locations of the closure on the container end.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for removing appendage tissue from avian species such as domestic fowl and principally from commercial chickens and turkeys is disclosed.  When the appendage is the beak, the method is known as debeaking and the invention is a method comprised of the step of burning and simultaneously cauterizing a hole through a portion of a bird's beak in order to damage the tissue and precipitate eventual rejection thereof out-wardly from the point of damage, and apparatus which includes means adapted to position the bird's beak between and in contact with opposing electrodes projecting into the apparatus which effect the burning as aforesaid.  A power source for the electrodes provides an open circuit voltage of suffic-ient magnitude to initiate current flow through the beak when opposing sides of the beak contact the electrodes.  With current flow initiated, the power source current increases toward a maximum short curcuit value sufficient to cause burning of the portion of the beak between the electrodes, while the voltage drops to a value sufficient to maintain the desired current.  The preferred control for the power source determines a time integral of current flowing through the bird's beak and, upon reaching a predetermined time integral of current value, the control de-energizes the power source.

Abstract: DIGITAL REMOTE CONTROL SYSTEM                       ABSTRACT         First and second redundant command signals are formulated in parallel-by-bit digital format by two ganged wafer switch sets in a control unit.  The first redundant command signal is stored in a shift register and subsequently strobed out, by clock pulses received from a remote unit, and transmitted to the remote unit in serial-by-bit format where it is stored and used to control the remote unit.  The command signal is subsequently clocked out of the remote unit and returned to the control unit in serial-by-bit format where it is compared against the second redundant command signal to insure that the remote unit has responded to the proper command.         A renewable timer is reset by the clock pulses.  If the clock pulses are interrupted for more than a predetermined time the renewable timer times out and indicates a fault.

Abstract: Abstract:            A process for the efficient production of power from non-gaseous carbonaceous fuels, such as coal, or heavy fuel oil, in a steam power plant in which the carbonaceous fuel is first gasified at relatively high pressure and tempera-ture by partial oxidation with oxygen to produce a fuel gas, the fuel gas from the partial oxidation reaction is expanded to a lower pressure in a turbine.  Undesirable compounds, e.g., sulfur compounds, are removed from the fuel gas, and the fuel gas supplied to a steam boiler for the production of power.            The process of this invention provides an effective means for conversion of gas fired steam generation facilities to coal or heavy fuel oil while at the same time increasing the power generating capacity of the installation, all with minimal atmospheric pollution.  The process is effective for the conversion of other types of gas-fired heaters and boilers to coal or heavy fuel oil.
