Title: Underground power cable system - uses silica gel to keep earth moist thereby increasing power loading by increased cooling
Inventor: HEUMANN HEINZ DR RER NAT
IPC: H02G9/00
Filed: 1974-08-27
Abstract: The underground power cable system uses silica gel around the cable assembly to keep the earth in that region moist, thereby increasing the loading that the power cable can carry. The silica gel can be mixed with other moisture retaining substances. The advantage of this method of preventing the ground from drying out around the cable, and thereby increasing the load that the cable can carry, lies in its simplicity when compared to existing methods that require either specially graded sand to be placed around the cable of a suitable cooling tube for the cable.

Title: Stabilised suspension for articulated vehicle - has separate systems for unit and trailer having dual dampers on driving axle
Inventor: MERKLE JOSEF
IPC: B60G21/067
Filed: 1976-04-15
Abstract: The towing unit has dampers on the front and rear axles (9, 12) linked by compensating lines so that when the one damper is moved in one direction the other one moves in the opposite way. The trailer rear axle has similar, but separate dampers, which are linked to a second set of dampers (13) on the rear axle of the towing unit. The effect of the two systems is that the whole unit operates as a semi rigid structure w.r.t. road irregularities. The magnitude of flexing about the coupling joint is considerably reduced, thus providing a smoother ride and less wear on the coupling. Dynamic stability is enhanced, enabling the unit to be braked more effectively.
