Abstract: ABSTRACT:                "CARTRIDGE FOR ROCK-BOLTING"          A frangible cartridge for anchoring a reinforcing element such as a rock-bolt in a borehole drilled in rock strata, for example an underground mine roof, contains as separate constituents (A) an aqueous liquid and an alkali metal silicate and (B) a gelling agent for the alkali metal silicate, the gelling agent being capable of forming a gel from the alkali metal silicate when brought into contact therewith as a result of the reinforcing element being caused to break the cartridge and mix together the constituents (A) and (B) within the borehole so as to form a grouting composition around the reinforcing element, the grouting composition when hardened serving to anchor the reinforcing element in the borehole.  In a preferred embodiment, a hydraulic substance such as a hydraulic cement is incorporated in constituent (B) and is hardened by the aqueous liquid present in constituent (A) when the contents of the cartridge are mixed by the reinforcing element.  The cartridge of the invention is safer for use, particularly in coal mines, than the conventional resinous cartridges.

Abstract: ABSTRACT OF THE DISCLOSURE   A plug contact assembly, comprising a female plug member and a corresponding male plug piece, is provided with an inter-locking means utilizing a locking tongue member which is protected from deformation and mechanical stress within the confines of an annular surrounding socket wall.  The tongue is a free-extending, resilient member having at least one detent hump formed thereon and arranged to engage into an associated detent recess formed along a generally flat base wall surface of the other plug section to establish a locking inter-connection of the plug contact members.  The tongue is spaced beneath an ad-jacent edge of a plug head portion to define therebetween a groove into which the base wall of the other associated plug section slides during interengagement of the plug members.  The groove and base wall are of approximately equal heights such that a tight-fit passage of the base wall into the groove is afforded, thereby assuring proper alignment of connector pins and plug contact holes during the joining together of the male and female plug members.

The introduction of the above derivatives into the backbone of polyester/polyether copolymer chain increases the photostability of the copolymerized product and increases the durability of these stabilizers toward further processing, such as dyeing and finishing, and toward normal use operations such as washing.  Copolymerization also minimizes any toxological effects which might arise from the use of the piperidine derived stabilizer additives.  Preparation of certain additives is also disclosed.
