Abstract: A vacuum packaging machine for producing sealed vacuum packages is disclosed which includes an improved sealing station. The sealing station has a heatable sealing member and a backing member for co-operation therewith, and deflector means are associated with the scaling member to deflect the air and moisture sucked off from the evacuating chamber of the evacuating and sealing station in operation in order to direct said air and moisture away from the sealing member to avoid contact therebetween, so that the air and moisture contained therein will substantially not be heated by the sealing member which is heated in operation. As a result, the moisture contained in the air sucked off from the evacuating chamber will not expand under the action of heat from the sealing member, and a substantially better vacuum will be achieved with the same capacity of the evacuating system.

Abstract: When the rate of increase of the load on a gas turbine with time is higher than a reference value, the amount of fuel supplied to the turbine is temporarily increased whereas, when the rate of decrease of the load with time is higher than a certain predetermined value, the amount of fuel supplied to the turbine is temporarily decreased. However, for a certain predetermined time interval after this decreasing of the fuel amount has ended, an increase in the amount of fuel supplied to the turbine is suppressed to a minimum even if the load on the gas turbine increases.

Abstract: Fuel flow to a gas turbine engine is controlled in response to power lever position and CDP by a hydromechanical section. The hydromechanical section includes a torque motor which may be activated to modify the fuel flow to the engine in response to a control signal produced by an electronic control section. The electronic control section senses a number of engine and ambient parameters and generates engine operating limits from these parameters. The limit corresponding to the lowest maximum engine speed is selected and referenced to actual engine speed for generating the control signal, thereby providing a closed loop engine speed control. At least one of the computed limits is an actual maximum engine speed for steady state engine operation and is used to recompute the engine scheduled speed so that the actual maximum engine speed is obtained at the maximum power lever advance position; in this way power lever dead band is eliminated.
