Abstract: A sensing apparatus is provided for use downhole, comprising a housing and sensing means with the housing containing a plurality of separable elements to which data acquired by the sensing means is transferred. The separable elements are releasable from the housing to convey the acquired data to surface. The separable elements have a spherical outer casing of around 1 to 10 cm diameter which surrounds a memory chip. The casing has a sealable aperture so that electrical connection to the chip can be established within the housing.

Abstract: A hinge type drop-leaf support includes a table hinge plate, a leaf hinge plate, and a slotted strut. Both the table hinge plate and the leaf hinge plate are hingedly coupled to each other and each are provided with respective depending legs. One end of the strut is hingedly coupled to table hinge plate leg and the other end of the strut is provided with an L-shaped slot. The leaf hinge plate leg is provided with a pin which engages the L-shaped slot. The L-shaped slot and the depending legs are dimensioned so that the use of a detent is obviated. If desired, a coil spring may be provided at the hinged coupling of the strut and the table hinge plate leg to bias the strut in a downward direction. The L-shaped slot has a long portion and a short portion which form an angle between them which is preferably acute.
