Abstract: An improved filling system for containers of mixtures of liquid and solid material where the liquid/solid ratio is critical is disclosed. A prior art problem was that sticky solid material would adhere to the receptacle or bucket in which it was delivered to a filling chute or funnel and it would also stick to the funnel. This problem is solved by putting the sticky solid in the buckets and by using the liquid to flush the funnel and by using an air jet to remove any remaining particles from the buckets which are upturned over the funnel. Alternately, a part of the liquid may be placed in the delivery bucket and when it is tilted or turned upside down to fill the container the remaining part of the liquid is used to rinse the receptacle. The filling system is especially useful for soups containing noodles or other pasta products.

Abstract: A refrigerant recovery and purification system particularly applicable to automotive air conditioning systems employs a centrifugal separator connected directly to the disabled automotive air conditioning system and which connects to a slack-sided accumulator and to a condenser chamber, all operating at near atmospheric pressure in a low pressure section. Oil and contaminants are separated by centrifugal action from the incoming refrigerant vapor stream and removed by gravity from the separator chamber. Condensing of the refrigerant vapor in the condenser produces a vacuum pressure for causing vapor to flow from the slack-sided accumulator to the condenser. A conventional refrigeration system supplies refrigerant liquid under pressure to a first evaporator coil within the condenser. The conventional refrigeration system also supplies high pressure liquid refrigerant to a second evaporator coil surrounding a liquid receiver connected by a conduit in series with the condenser and the accumulator.

Abstract: Containers (such as metal, glass, plastic, fiber, but not limited thereto) are sterilized in a section of the apparatus having a helical or spiral belt conveyor within an insulated casing through which air above atmospheric pressure at up to about 500.degree. F. is circulated by means of a heater and blower, in a recirculation path. The containers then travel along a straightline encased conveyor where sterile air above atmospheric pressure prevents ingress of non-sterile ambient air. During part of the path through the straight-line conveyor, the containers are driven by a helical screw which forces the containers into close proximity (in fact the out-turned flanges of the containers preferably overlap). Pre-sterilized, preferably cooled, product is delivered into the containers preferably through a curtain, slit-type filler. Other fillers, such as rotary fillers, may be used. The speed of the containers is timed to deliver the desired product volume into the containers.
