Title: Long distance transport of fossil fuels - portion converted to methanol and recombined with remainder
Inventor: GRUBER KURT DR ING
IPC: F17D1/00
Filed: 1974-10-25
Abstract: Long distance transport of fossil energy sources (fuels) by converting a portion of the fossil fuel to methanol before transport and then combining this with the fuel to be transported. More especially, where the fossil fuel is coal, that part not converted to methanol is converted to liquid hydrocarbons which are mixed with the methanol prior to transport. Where the fossil fuel is petroleum or products produced from this and/or natural gas, a part of the petroleum and/or at least part of the natural gas is converted to methanol and mixed with the remainder of the petroleum, the mixture then being transported over long distances to a refinery for subsequent separation of the methanol. In the case of solid fuel such as coal, pipeline transport is achieved without the pipeline wear involved in transporting a suspension of coal in water, while in the case of natural gas, the costs of refrigeration and insulation of the pipeline or the high costs of compressed gas transport are eliminated.

Title: Cylinder lock operated by magnetic key - rotary magnets prevent radially moving locking bar moving
Inventor: BOEVING EGON
IPC: E05B47/00
Filed: 1974-03-21
Abstract: Permanent magnets (34) embedded in the key rotate the cylinders (17, 18, 19) about pivots (16) by action on the associated magnets (21). When all magnets are aligned the slots (22) face the projections (23) on the locking bar (11) which can then slide radially inwardly against the pressure springs (24). The inward movement of bar (11) is produced by the rotation of the barrel which brings the chamfered edge (10) of the bar into contact with the internal surface of the cylinder (1). Returning the key and withdrawing it rotates the cylinders (17) so that the projections (23) do not register with slots (22) and the locking bar cannot move inwards to release the barrel. Any attempt to force the lock causes the projections to press on the magnetic cylinders which cannot then turn.
