Abstract: A cable closure end cap arrangement is provided, to achieve a sealing between a cable splice closure, and a cable end in communication therewith. The arrangements according to the invention may be adapted to accommodate more than one cable extending into an end of a cable closure. Preferred arrangements comprise a composite of inner and outer members, each having a bore therein. Each bore is preferably defined by an arrangement of concentric rings, or a circular ridge/trough arrangement. The circular rings include transverse walls extending therebetween, in a preferred manner permitting an accordion-like flexibility. The accordion-like rings accommodate: cables of different sizes; cables at various angles relative to the end cap arrangement and the cable closure; and, movement of the cable closure, for example upon an aerial messenger wire. End cap arrangements according to the present invention are mounted by means of a slit in communication with each bore.

Abstract: A splice closure for environmental protection of aerial cable splices is provided. The splice closure includes a double-wall construction facilitating closure strength, construction and operation. A preferred construction is provided which facilitates extension of an intact closure, by means of a one-half section cut from a second, identical, closure. A trough and drain arrangement facilitates drainage of water from an interior of the closure, to the environment. Preferred orientation of an opening hinge in the closure, facilitates access to an enclosed cable splice area. A preferred arrangement is provided, for association of end cap arrangements with the closure.

Abstract: A diazo developer is described which is useful for both ammonia vapor developing and for thermal developing. A heated chamber is provided with inlet and outlet slots through which the sheets pass during operation. Adjacent the inlet slot is a pair of inlet rollers that carry the sheets through the chamber. Adjacent the outlet slot is a pair of outlet rollers. At least some of the rollers are driven by a motor and one or more are preferably yieldably biased toward its mating roller, e.g. by the provision of a thin ribbon-shaped sealing strip engaged against the roller at a point opposite the nip or contact line between the rollers to yieldably bias them together while at the same time sealing the chamber against the leakage of vapor when used. Side plates are provided at the ends of the rollers and resilient gasket sheets formed from elastomeric material are compressed between the roll ends and the fixed side plates to seal the chamber.
