Abstract: The atmospheric pressure actuated alarm of the present invention comprises a pressure transducer which senses the atmospheric pressure and produces an electrical transducer signal in response thereto. A difference amplifier is connected to the pressure transducer for measuring the transducer signal and for producing an output signal whenever the transducer signal is of a magnitude outside a predetermined range. An operational amplifier is connected to the difference amplifier for amplifying the transducer signal. A latch is connected to the operational amplifier for receiving the amplified signal. A signal alarm and a power source are connected in series with the latch. The latch is changeable from an open condition to a closed condition in response to the amplified signal being greater than a predetermined magnitude. When the latch moves to the closed condition, it connects the power source to the alarm signal and causes actuation of the alarm signal.

Abstract: A dispensing head having a plurality of prong-like nozzles is useful for impregnating meat with tenderizing and flavoring liquids. It may be fitted onto a pressure dispenser of the conventional type containing a bag to hold the liquid, a gas pressure space thereabout, and a reciprocable dispensing valve. The head so utilized has an inlet leading to a flushable chamber communicating to several prong-liked nozzles which project on parallel axes from a meat pressing surface, preferably having a rim. Pressing this surface so spreads the meat against the sides of the nozzles as to seal them against the escape of liquid dispensed under superatmospheric pressure, thus forcing it to impregnate the meat. The dispensing head is readily flushed; and provisions are made for re-mounting on the valve stem without discharging the contents of the container.

Abstract: A dispenser head having a plurality of prong-like nozzles is useful for impregnating meat with tenderizing and flavoring liquids, and similar purposes. It may be fitted to a conventional pressurized dispenser of the type having a tubular stem. Preferably constructed in two parts, the lower or manifold part has a bottom inlet; the upper or outlet part has a number of prong-like nozzles on parallel axes; and interfitting portions provide sealed passages to distribute the dispensed liquid to the nozzles.
