Abstract: A PVC heating blanket preferably includes a power unit, a heating blanket portion, and a fastening device. The power unit preferably includes a thermostat and a power cord. The thermostat controls the flow of electrical current to the heating blanket portion. If the heating blanket portion gets too hot, the thermostat will stop the flow of electrical current to the heating blanket portion. The heating blanket portion preferably includes a heating element and a flexible outer cover. The heating element is retained within the flexible cover. The fastening device extends from a middle of one edge of the heating blanket portion. The power unit is located adjacent the one edge of the heating blanket portion.

Abstract: A concrete vibrator adapter preferably includes an adapter housing, a drive shaft and at least one rotary bearing. The adapter housing preferably includes a bearing bore formed in one end and a shaft hole formed through a bottom of the bearing bore. A ring thread is formed on an outer diameter of the adapter housing at a bore end to threadably receive a threaded retention ring of a vibrator cable. The drive shaft preferably includes a bearing portion, an input portion and an output portion. The bearing portion includes a first bearing diameter, a bearing flange and a second bearing diameter. The first bearing diameter receives a first bearing and the second bearing diameter receives a second bearing. The input portion extends outward from the second bearing diameter. The output portion extends outward from the first bearing diameter.
