Abstract: The disclosure illustrates and describes a sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are effective through the mandrel assembly on which the container bottom closures are formed and sealed. This is accomplished by forming longitudinal channels through each mandrel and connecting same to separate compartments formed within the hub, and providing means for communicating a suitable sterilant fog through respective compartments and channels at the station where each bottom-formed container is stripped from its respective mandrel. The usual fast stripping action tends to create a vacuum within the container which aids the dispersement of the fog onto the entire inside surface of the container, sterilizing it prior to the subsequent filling operation.

Presence of articles sensed at approximately the bottom of the open side of the fill box cause the fill box to be incrementably lowered into the storage box so that articles entering the fill box enter at a level with minimum fall to the bottom wall of the fill box or to a previously deposited layer of articles. As the fill box is lowered a curtain wall closes the open side below the point of entry of the articles.

Abstract: An electronic engine control for a gas turbine monitors a plurality of speed and temperature parameters. For each of the parameters a setpoint signal is produced that can be either fixed or variable and which is compared against the parameter signal to produce a difference signal proportional to the amplitude and rate of change of the difference between the parameter and setpoint signal.A gas generator minimum control signal is high selected with a power turbine minimum speed signal. The resulting high selected signal is then low selected with the power turbine average temperature and gas generator control signals. A low selection provides for fuel control to drive the most extreme variable parameter back to its setpoint by means of a feedback loop to an output driver circuit within a fuel valve card.

Abstract: A cold trap for removing contaminants from a vapor stream has a coolant expansion chamber extending the length of the cold trap housing and a stack of spaced-apart, perforated disk-shaped baffles mounted about the outside of the expansion chamber. A coolant feed tube is mounted inside, and extends the length of, the expansion chamber. Coolant exits the feed tube into the expansion chamber through a small tangential outlet hole in the bottom of the feed tube to increase coolant turbulence and heat transfer efficiency. The cold trap causes the vapor stream to pass through one or more centrifugal separation and condensation stages defined by the baffles to remove solid particles, mists and condensates. A reversible refrigeration system is used both to cool the cold trap and to rapidly defrost it. This permits the rapid liquification and drainage of collected contaminants.

Abstract: A system for minimizing the energy consumption in a central air conditioning unit incorporating a refrigeration unit which is normally in operation to supplement or substitute for the cooling effect of outside air.

The energy content of the discharged washer air may be modified by modulating dampers controlling the proportion of outside and recirculated air, and also by modulating the washer which provides evaporative cooling and, in addition, cooling by refrigeration.

Abstract: A method and control system for operating a refrigeration unit to permit random loading and unloading sequences of multiple compressors and unloaders. The random loading and unloading sequences of the two circuits of compressors and unloaders is performed by a microprocessor. A random sequence is selected at start-up and the selected sequence loads the compressors to full load, where upon another random sequence is selected to unload the compressors.The compressors are also loaded in response to the water temperature leaving the chiller. The leaving water temperature is compensated for by a return water temperature which determines the temperature drop through the heat exchanger. The temperature drop is divided by the number of active stages to determine the drop/stage, which is an indication of how the leaving water temperature will change when a capacity stage is either added or subtracted.

Refrigerant pressure at the evaporator outlet is used to control on/off cycling as well as capacity cycling, and the rate of decrease of such pressure is used as an indication of the air conditioning load.

Abstract: An absorption type heat transfer and thermally powered temperature pressure potential amplifier system for storing energy by distilling and separating solute from a solution of the solute and a solvent at a low temperature, then amplifying and recovering the temperature and/or vapor pressure potential difference between the solute and the solution at a higher temperature in the form of heat transfer or its mechanical power equivalent. One working fluid is a solute having a low boiling point, the other a solution of the solute in a solvent having a high boiling point such that mutual solubility is poor at low temperatures as indicated by a small vapor pressure difference between solute and solution, and in which the vapor pressure difference between solute and solution greatly increases at higher temperatures. This permits the vapor pressure potential difference to be released in the form of mechanical work when vapor from separated solute is reabsorbed into solution in an absorber at the higher temperature.

Abstract: In a security door lock a pivoted detent deadlocks the bolt by engagement of a stump in pockets provided in the bolt. The detent is normally held in its locking position by a cam surface on the thrower and by a pack of detainers. Rotation of the correct key aligns notches in the detainers with a probe on the detent and also positions a second cam surface of the thrower adjacent to the detent, so the detent can pivot to its unlocking position under the action of a spring, and thereby free the bolt. After the bolt is shifted the final rotation of the key re-engages the cam surface against the detent to drive the detent positively back to its locking position. If required, the bolt can be double-thrown by a second ("master") key which lifts the detainers to higher positions so that second notches in the detainers now align with the detent probe. This higher lifting of the detainers also lifts a dogging slide so that the stump of the latter can pass over a projection on the bolt tail.
