Abstract: A multistage cementing assembly is used for cementing casing in a borehole. A subsurface tool on the casing holds a subsurface plug therein using a temporary retainer. The subsurface plug is located in a subsurface location below one or more stage tools or cementing collars on the casing. First stage cement passing down the casing can pass through a passage of the subsurface plug to flow out of a float valve. A wiper plug passed through the casing behind the cement is then engaged with the subsurface plug. Pressure buildup can release the two plugs as a unit from the temporary retainer. Before reaching the float valve, a deformable ring on the subsurface plug can engage in a locator ring on the casing to indicate the plug unit's location during operations. Eventually, additional stages can be cemented using the one or more stage tools uphole on the casing.

Abstract: A method and apparatus for supporting and controlling a candle in an candelabra and other candle holders is disclosed. A candle support apparatus includes an outer shell or tubular body and inner shell or tubular body. The outer shell is typically a rigid casing that attaches to the candelabra or other candle holder. The inner radius of the outer shell is typically larger than the candle. The inner shell is typically resilient and has a radius smaller than the candle. The inner shell includes a substantially cylindrical portion having a longitudinal axis. The inner shell further includes a number of prongs sharing a common longitudinal axis with the substantially cylindrical portion. The end of the outer shell that is adapted to connect to the candelabra is a closed end with a hole adapted to receive a screw, bolt or other device used to attached the support apparatus to the candelabra.
