METHOD OF MAKING PRECISELY POSITIONED COMPOSITE STRUCTURE UTILIZING NON-PRECISE FIBERGLASSING TECHNIQUES

摘要

A water tight protective casing which includes an outer fiberglass box with an inner metal frame in which four electronic logging panels, for example, can be placed, two to either side of the main central division in the frame, for transportation particularly in a marine environment. The casing also includes a fiberglass top having a generally pyramidal shape in order to evenly distribute the sealing stresses and pressures from the central top point along the gasketed, sealing interface between the top and the bottom of the casing. The inner frame comprises six, peripherally spaced, vertical channel iron members, the inner one being doubled, fastened to a lower and upper box-like auxillary frame. The inner frame itself contains the four electronic panel boxes which are situated within and between the chanel iron members which define the panel chambers. Centrally located within the frame is a vertical support terminating in a threaded male member or stud to which is attached the top of the casing by means of a special locking nut.
