Title: Open pit mining method for minerals - has overburden strip spoil passed out through galleries to winding road for surface dumping
Inventor: PARASCHIV PAUL DIPL ING
IPC: E21C41/16
Filed: 1975-06-30
Abstract: The open pit mining method employs underground removal of the overburden arising during the period in which the mineral deposit is being opened up for extraction. The method enables the pit to go deeper whilst retaining the angle of repose on the stops either side of the pit. The spoil arising during opening-up operations is removed by a system of link galleries to a winding road placed out of the area affected by stripping operations and which carries the spoil, i.e. overburden, to the surface for disposal. Using the galleries enables the benches to be kept narrow as compared with conventional bench areas. The angle of repose of the rock is similarly held.

Patent DE-2602035-A1 (DE)
Inventor: KRAUS HEINZ ING GRAD
IPC: H04N3/18
Filed: 1976-01-21
Abstract: The output transformer (8) of the horizontal deflection generator carries the effective power necessary to supply the receiver circuits. The horizontal deflection generator is controlled by a horizontal oscillator (14) at line frequency. When the device is switched on, the voltage for the horizontal oscillator (14) is supplied by an output transformer (21) of a free-running (i.e. it cannot be synchronised) oscillator (18). The voltage at the output transformer (21) of the free-running oscillator (18) is rectified before it is supplied to the horizontal oscillator (14). Perturbing phase jumps when the device is switched on are avoided because only the horizontal oscillator is synchronised. <IMAGE>

Title: Heat pump for space heating - uses high thermal capacity building walls to prevent icing of heat exchangers
Inventor: WEISS HANS
IPC: F24D11/02
Filed: 1976-02-10
Abstract: The building external wall has an outer leaf of high thermal capacity and a structural inner leaf also of high thermal capacity. The space between them is filled with insulation. The refrigerant circuit of a heat pump runs through a plate heat exchanger between the insulation and the inside of the outer leaf. This forms an evaporator which takes heat from the cold outer leaf but is not exposed to the atmosphere and therefore does not ice up. A heat pump transfers the heat absorbed in this way to a heating medium which flows through a similar heat exchanger between the insulation and the outside of the inner leaf of the wall to give up heat when cooling is required.
