Abstract: Well apparatuses with device for preventing their relative rotation with respect to adjacent well apparatuses and anti-rotation devices for well apparatuses, including, but not limited to, plugs, float shoes, float collars, jars, and clutch devices for packers. In one embodiment self-aligning non-rotation devices are provided with body members having protrusions extending from recesses therein, the protrusions and recesses configured and disposed so that two opposed devices which initially misalign will co-act to align themselves. In another embodiment an intentional "sloppy fit" is provided between two opposed devices to facilitate device contact and co-action. In various embodiments unwanted separation of two devices is prevented due to the configuration of protrusions.

Abstract: A drinking vessel retainer for use upon a seat cushion of an automobile. The retainer has a wedge shaped base to hold the vessel upright on sloping seats, and is anchored into the space between the seat and backrest cushions by a flat extension. An open ended, reversible insert, flanged inwardly at one end, enables the holder to support both large and small vessels. According to one aspect of the invention, the retainers are adapted for use in pairs connected in tandem across the seat to save space.
