Title: Hydrotorting of oil shale with synthesis gas in the presence of added
IPC: C10G1/06
Filed: 1971-02-01
Abstract: Oil is recovered from oil shale by injecting into the oil shale reaction zone a H2-rich gas (at least 45 vol. H2) at 850-1000 degrees F and 300-1000 psig and 0.01-0.6 tons of water per ton of oil shale, the H2 rich gas being fed in an amount to supply sufficient heat to pyrolyse the oil shale and to hydrogenate the shale oil produced. Water is recovered from the effluent and part at least of it is recycled to the reaction zone. The oil shale may be present in a fractured underground formation, so effecting the pyrolysis and hydrogenation in situ. The H2 rich gas is suitably a synthesis gas produced from the being oil product, 3-13 vol. % of the shale oil product being sufficient to supply all the H2 required for the process. The process gives a hydrogenated, desulphurised and dinitrogenated shale oil at relatively low pressure and in a yield above 110% of the Fischer assay.

Title: Fresh air ventilation system for buildings - has intake automatically controlled by intensity of daylight solar radiation
Inventor: VETTER HARALD ING GRAD
IPC: E06B7/28
Filed: 1974-08-17
Abstract: A damper (1) is formed by a series of aluminium profile blades (2) linked together by a rod running along their whole length and held in a rectangular aluminium frame (3). They are pivoted on axes through their centres and are all moved together by the rod linking them. A bimetal strip (4) pivoting on a shaft (5) is contained in a box (6) which shields it from extraneous thermal effects and has a window (6a) through which daylight enters and heats the bimetal strip. The free end of the strip is connected to the linkage rod joining the blades and as the bimetal turns it moves the rod and thus turns the blades to close the damper progressively as the daylight intensity rises.
