Abstract: A device for manually loading, moving and discharging material such as snow, sand or the like. The device (10) has a carriage (12) and a bucket (22). The carriage has a yoke (14), defined by a pair of forwardly-extending yoke arms (20) and a pair of rearwardly-extending handle arms (16), as well as a pair of wheels (18). The bucket is rotatably positioned between the yoke arms on a pivot axis. The bucket is selectively rotatable about the pivot axis between a first position, in which rotation of the bucket is prevented, and a second position, in which rotation of the bucket is also prevented. The first position is used for loading the bucket and the second position is used for discharging the bucket contents. Some embodiments have a third position, which is used to secure the load in the bucket during transport.

Abstract: A programmable atmospheric stabilizer uses one or more sensors for detecting the condition of potentially hazardous materials within a container or some other enclosed atmosphere. The sensors connect to a first threshold detector which activates a first order correcting device when the sensor detects a first order hazard. The sensor also connects to a second threshold detector which activates a second correcting device when the sensor detects a second order hazard. The first correcting device may be a fan, and the second correcting device may include an alarm. A variety of different sensors can be connected to one monitoring unit and a variety of different correcting devices can be activated by the monitoring unit. Each monitor can be connected to a central location where the sensed levels and the activity of the correcting devices can be monitored.
