Abstract: ABSTRACT OF THE DISCLOSURE      A machine and method for evacuating sealed packages formed from flexible sheet material and for flushing or filling, as required, the evacuated package with an inert gas.  The product enclosed within the package is preferably a food product such as luncheon meats, sausage, cheese, or the like.  In constructing the package, one or more spaced apart apertures are formed in one sheet and a slit if formed in the other sheet so that preferably the slit will be on the opposite side of the package from the apertures.  An initial peripheral seal is made between the two sheets to enclose the slit, apertures and product.  The package is then evacuated through the slit with the sheets being separated and then the slit is sealed and gas introduced through the apertures, or, for a gas flushed package, the slit may be sealed after gas is introduced.  Next the apertures are sealed thus forming a gas flushed or filled package.

Abstract: Abstract of the Disclosure Wall sections for prefabricated buildings are constructed so that they have one stud and one short bottom plate whose length is equal to the design stud spacing at 90° forming an "L".  The sections are covered inside and outside with inside and outside finish.  Each section is insulated with fiberglass insulation in batt form.  The above description is meant to indicate ordinary building construction.  The new sections would be similar except that the stud and plate would be split in two in the plane of and between their covering coats with one part being fixed to the outside finish and the other part being fixed to the inside finish.  The fiberglass insulation would not be cut and would be left adhered to the inside surface.  For shipping purposes and to cut bulk, one section half would be spun around 180° and offset so that the two "L" shaped framing members would form a rectangle and then it would be crushed against the other half section, compressing the resilient fiberglass insulation to less than a small fraction of the wall thickness and fastened tight in this manner for shipment.  After shipment, the half sections are set in their proper relation allowing the insulation to expand fully and the sections are fixed into the building.

Abstract: TITLE OF THE INVENTION     "CUSHIONED VIBRATING MEANS"     ABSTRACT OF THE INVENTION     This invention is directed towards the combination of a pressure-switch operated vibrating motor, enclosed within a cushioning material, such as synthetic or natural foam, having an enlarged surface area relative to that of the motor.  As a person applies pressure on said enlarged cushioning means, as by leaning on the cushion, the pressure switch is engaged to close a circuit thereby starting the vibrating motor enclosed within the cushioning means.  The cushioning means acts as a damping means for the vibrating motor for greater comfort than would otherwise occur if the vibrating motor were not so enclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           A burner nozzle for feeding the combustion zone of a vapor generator with a mixture of pulverized fossil fuel and air in a controlled, turbulent flow.  The fuel pipe for the burner nozzle has a relatively small diameter so that a relatively small amount of primary air is sufficient to carry the fuel to the burner nozzle.  An atomizer is fitted to the outlet of the fuel pipe for introducing atomizing air in a generally tangential direction relative the the axial flow of the fuel.  The air creates turbulence to swirl the fuel and distribute it in a controlled manner to provide for even burning of the fuel in the combustion zone.  A pipe of smaller diameter may be concentrically positioned within the fuel pipe so that alternative fuels, such as gas and oil, may also be efficiently used with the burner nozzle.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and process for automatically measuring and controlling the instantaneous flow rate of a liquid in a piping system by varying the speed of a centrifugal pump in response to a flow rate signal determined indirectly by sampling two flow-related parameters associated with the pump and pump motor and then converting in an on-line computer the two measurements to the corresponding unique flow rate value by the use of previously determined mathematical relationships stored in the computer.          The mathematical relationship are derived from data correlating flow rate with the two flow-related variables, which data is taken with a flow meter and control valve temporarily installed in the piping system during the "shake-down" testing of the piping system.  A third flow-related variable is sampled, a pair of flow rate values determined, and an alarm activated in response to the difference between the values to provide the additional feature of pump mechanical performance monitoring.          A viscosity-related property of the fluid also is determined indirectly by the use of a mathematical relationship whenever three flow-related variables are monitored, the mathematical relationships having been derived from data taken by running fluid of different but known values of the viscosity-related property through the piping system during the "shake-down" testing.

Abstract: ABSTRACT OF THE DISCLOSURE     An alarm system is disclosed for generating alarms when torsional oscillations of a rotating shaft exceed predetermined limits and fail to subside at a predeter-mined rate.  The alarm system receives a torsional oscillation input signal developed by measuring the deviation of instantaneous shaft angle from a uniformly increasing value.  The input signal is converted to a direct current torsional oscillation signal representative of the magnitude of oscillation.  The torsional oscillation signal is com-pared against a first adjustable reference voltage re-presentative of a first maximum magnitude of oscillation.          A low level alarm signal is generated when the oscillation signal exceeds the first reference voltage for a pre-determined length of time.  The oscillation signal is also compared against a second reference voltage repre-sentative of a second maximum magnitude of oscillation.          An output signal is generated when the oscillation signal exceeds the second reference voltage.  The output signal is then employed to activate a rate of decay circuit which generates a signal representative of the rate of decay of the oscillation signal. This representative rate of decay signal is compared against a third reference voltage re-presentative of a minimum acceptable rate of decay.  If the representative rate of decay signal exceeds the third adjustable reference voltage a high level alarm signal is generated to indicate that the second maximum magnitude of oscillation has been exceeded and that the minimum required rate of decay has not been attained.
