Abstract: ABSTRACT            The invention relates to a cargo pallet preferably intended to transport corrugated cardboard containers and the like.          The pallet is characterized in that it is assembled of two components in the form of struts 1,2 provided with blocks and capable in carrying position to be interlocked by action of gravity, one said strut 1 entering a groove in said second strut 2. The struts are pivotal relative one another so as to be located in parallel with each other in a trans-port position, the pivotal movement occurring about a central block 3 on one strut 1.          At a particularly favourable embodiment a locking means is provided between the pallet and a loose deck or the lower surface of a cardboard packing or the like by means of two or four upright short cylindric guides (8) located on the upper surface of the pallet (1), which guides preferably have the same diameter as the pallet feet (4) and are intended to co-operate with corresponding holes (9) in the lower surface of the cardboard packing or the like, in order to prevent the packing (11,13,14) to slide to either side in relation to the pallet.

Abstract: RIBBON FEED AND LIFT MECHANISM FOR A TYPEWRITER       Abstract In a daisy wheel or rotary print wheel typewriter, a single motor is employed to accomplish both ribbon lift and feed for typewriter ribbon and correction ribbon loaded in a cartridge assembly.  A single motor drive moves the cart-ridge assembly support about an axis to present the type-writer ribbon or the correction ribbon to the print point at the print line.  When the elevation of the cartridge assembly about the axis is such to permit normal typing upon the typewriter ribbon, only the feed ratchet for the ribbon is engaged.  Alternatively, when the rotation is greater, for example, for typing on the correction ribbon, the added elevation of the cartridge assembly effects disengagement of the normal ratchet feed for the typewriter ribbon while allowing advancement of the correction ribbon.

Abstract: ABSTRACT The invention relates to a training projectile stabilized by its own rotation and which comprises a conical nose section, a cylindrical intermediate portion and a tail section and which is provided with aerodynamic surfaces in the form of fins or grooves on the cylindrical intermediate portion.  The fins or grooves are substantially radially directed and parallel to the symmetrical axis of the projectile.  By the fins or grooves arrangement a braking effect is imparted to the projectile to reduce its rotational velocity after launching, so that the projectile at a specific, critical rotational speed becomes unstable and tips or tilts.  This means a substantial increase of air resistance and a corresponding reduction of the projectile velocity forwards.  By an appropriate adjustment of the fins or grooves it is possible to locate the instability just behind the target distance when training.  The ballistic properties of the training projectile are maintained up to the target distance but the maximal firing range is reduced compared with normal live ammunition.

Abstract: ABSTRACT OF THE DISCLOSURE Raw shale is supplied to a pyrolyzer where it is pyrolyzed by fuel gas and hot spent shale derived from a gasifier.  Typically, the raw shale is Eastern U.S. shale and the pyrolyzer includes a fluidized bed.  The pyrolyzed shale having given up its oil and volatile hydrocarbons, rises to the top of the fluidized bed of raw shale whence it is transferred to the gasifier.  Oxygen and steam are supplied to the gasifier.  This composite gas reacts with the carbon of the pyrolyzed shale in a fluidized bed to produce synthesis or fuel gas.  The oxygen is supplied in such quantities as not to react completely with the carbon in the pyrolyzed shale.  The steam reacts with the excess of carbon.  Predominantly hydrogen and carbon monoxide are produced;  in  addition  there  is  a  smaller quantity of carbon dioxide and methane. This hot fuel gas is trans-ferred to the pyrolyzer.  In addition, hot spent shale is transferred to the pyrolyzer.  The hot fuel gas fluidizes the raw shale in the pyrolyzer.  The hot gas and the hot spent shale heat the raw shale separating the shale oil and product gas including volatile hydrocarbons.  The oil is condensed and collected, the fuel gas is collected for utilization in the above process and also for other pur-poses.
