Title: Tension rod for attachment to cables - using a shrink fitting plastics sleeve filled with casting resin
Inventor: SCHOENEBECK KARL-HEINZ
IPC: H02G1/08
Filed: 1975-03-07
Abstract: Tension rod is attached to a cable by inserting an end of the rod into the cable, and inserting the rod and cable end into the open end of a heat shrinkable cap containing a reservoir of casting resin. The upper portion of the cap is heated to shrink the upper sides of the cap into engagement with the cable, then the lower portion of the cap is heated to shrink the cap volume and press the coasting resin into the cable core. Method is for fitting a tension rod to a telecommunications cable to enable it to be pulled into a duct. Assembly bonds the rod to the cable so that tension applied to the rod is uniformly transmitted to both the core and jacket, preventing relative displacement during pulling. The assembly also seals the cable end preventing ingress of moisture.

Title: Dust remover for bulk goods trough - uses pivoted flap to close filling aperture
Inventor: SCHMIDT WILLI
IPC: B65G69/18
Filed: 1975-06-10
Abstract: The dust remover is for a receiving trough for bulk goods, esp. cereals and foodstuffs. The filling aperture (3) of the receiving trough (1) is closed by pivoted flaps (4). The flaps are pivoted by the weight of the bulk goods into an opening position corresponding to the amount of the goods.
