Abstract: A process is disclosed for manufacturing solid fuel which includes the steps of mixing a biomass, a heavy hydrocarbon and a sorbent to form a hydrocarbon-biomass slurry, the biomass being characterized by a particle size and distribution of about 50% between about 250-2000 .mu.m and about 50% less than about 250 .mu.m, and more preferably as follows:______________________________________ distribution particle size ______________________________________ 10-20% 1250-2000 .mu.m 10-20% 500-1250 .mu.m 10-20% 250-500 .mu.m balance .ltoreq.250 .mu.m ______________________________________compacting the slurry to form a solid fuel agglomerate; and baking the agglomerate so as to form a solid fuel briquette having a resistance to compression of at least about 22 kg/cm.sup.2. The mixing step includes the step of mixing the biomass, hydrocarbon and sorbent in the following proportions, by weight: ______________________________________ biomass 50-70%; hydrocarbon 30-45%; and sorbent 5-10%.

Abstract: A lockable lock is disclosed, particularly for drink distribution trolleys in aircraft, comprising an additional latch (20) for locking the sliding bolt (7) whose movement is dependent on the pivoting movement of an operating and unlocking lever (8) which also displays, through the aperture (13), the provisioned state of the trolley, the lever (8) being actuated by a key fitted on its shaft (9).

Abstract: Device for ensuring the vertical suspension of the chassis of a bogie and the longitudinal and transverse coupling of each box of the chassis in a driving or carrying railway bogie, comprising a vertical suspension spring through which the bogie frame is supported on the axle box, thereby creating a rotary torque on this box, and including two flexible couplings mounted spaced in altitude between the frame and the axle box so as to be compressed when the axle box tends to rotate under the effect of the rotary torque.
