A muscle energy converter for a patient. The apparatus includes a semiconductive wafer and electrical connectors attached to, preferably, one of the edges of the wafer. These cooperate with one another such that on rotating the rotary cap in the opening direction for the first time the self-opener sleeve firstly in the pour-out spout may be pushed vertically downwards and subsequently may be rotated by approximately 360\xb0 in the horizontal. The use of such DSLAMs provides the network service provider with flexibility in implementing and maintaining the network. Photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield dye images that have unexpected and substantial improvements in the stability of the formed image dyes.
