The system is such that flexible conductors can be connected between the socket contacts and the terminal block contact screws. As shown, the terminal block is in two relatively movable parts which can be relatively locked by a screw passing through an elongate aperture in one part. Hooked flanges on the terminal block engage over lips formed in the rear wall of the duct so that the terminal block can be slid along the duct before being locked in position. When in position the bared end of a flexible conductor can be inserted between a contact screw in the terminal block and a conductor in the rear wall of the duct and the screw tightened to clamp the conductor. The other ends of the three conductors so clamped can be connected to the socket terminals. The socket is screwed in position after the cover for the duct front has been cut and snap fitted into position and after the two socket mounting brackets have been placed in the correct position. The screw receiving centre arm of each bracket is vertically adjustable on the bracket to receive the screws. The outer arms of each bracket engage behind lips in the duct. A series of couplings is described whereby the duct can be continued around external or internal corners or make turns through 90 degrees in its own plane.

Title: Improvements in or relating to filament-wound chambers having multiple off-axis ports
IPC: F17C1/16
Filed: 1963-10-30
Abstract: 996,450. Rocket motors. UNITED STATES RUBBER CO. Oct. 30, 1963 [Dec. 24, 1962], No. 42785/63. Heading F3A. [Also in Division B8] The invention relates to structures such as rocket motors that are wound with filaments to reinforce them and in which such structures have at least one oblate end 14, Fig. 1, formed with off-axis ports 16. The structures are reinforced by girth windings 12 and end-over-end axial windings 34, Fig. 3. According to the invention the endover-end axial windings 34 are reinforced by reinforcement rings 36 of filamentary material extending around each off-axis port 16 and by what are called " zonals 40 " of filamentary material, the filaments of which follow the latitudinally - extending principal lines of circumferential stress on the oblate end and connect the left half of one ring 36 with the right half of another ring 36. The zonals 40 are initially wound on specifically designed mandrels and to facilitate stripping of a completed zonal from its mandrel a layer of polyethylene is first applied to the mandrel, followered by a layer of cloth and then the filamentary windings embedded in an epoxy resin binder. The resin binder is dried and partially cured before removal from the zonal mandrel by cutting across the filaments. The cloth helps the resin maintain the filaments in fixed relative position after removal from the zonal mandrel. The oblate end 14 may be reinforced by a number of filamentary layers according to the following sequence:-axial windings 34, rings 36, zonals 40, rings 36, axial windings 34, rings 36, zonals 40, rings 36 and so on. The zonals 40 may be applied in sets of four, each zonal commencing 90 degrees ahead of the other and extending over half of the circumference of the end to be covered. This results in two layers of zonals each layer covering the end circumference once. The zonals may overlap.
