摘要： There is disclosed a cable closure which includes a central closure body and a pair of end caps preferably made from structural foam situated at each end of the closure body. There is also disclosed a cable block which includes void filling material selectively inserted among the insulated conductors of the cable and a directional control device which consists of a conduit also selectively inserted among the insulated conductors of the cable. Together the cable closure, cable block and directional control device make up the splice closure system. There may also be provided a heat recoverable seal adhesively attached to the cable closure in which case there will also be provided means for preventing milk-off of the seal from the cable closure. finally, there is disclosed a method for forming the cable block.

摘要： The invention relates to the production of silica reinforced rubber incorporating a novel azo-silane coupling agent which does not depend on the vulcanization reaction to effect coupling to the rubber. The novel coupling agents are of the general formula:Y -- X -- CO -- N .dbd. N -- CO -- X.sup.1 -- Zwhere X and X.sup.1 are the same or different and each is an imino group, an oxygen atom, or a substituted or unsubstituted methylene group; Y is a substituted or unsubstituted alkyl, aryl or aralkyl group or is the same as Z; and Z as an alkyl, aryl or aralkyl group which has an substituent at least one silane group of the formula: --Si(OR).sub.3 or --OSi(OR).sub.3 in which R is a straight or branched chain alkyl group. The azo-silane is typically used in amounts of from .1 to 10 pphr. Silica reinforced rubber vulcanizates produced using the azo-silane can have improved properties e.g. abrasion resistance, scorch resistance and resilience as compared with vulcanizates made using conventional coupling agents.

摘要： A gel and container means capable of protecting a binding post and drop wire from moisture and corrosion is provided which will effectively prevent the exposure of the drop wire and binding post cap and screw from moisture and corrosive atmospheres without the need for a pressure maintaining means other than the combination of the cap and gel. The pressure of the gel is maintained on the binding post through the extraction of plasticizers from the container means causing a shrinkage.
