Abstract: The invention relates to a stretcher, especially for ambulance vehicles. The stretcher (1) has a retaining cushion (4) for retaining purposes in the event of abrupt movements in the longitudinal direction of an ambulance, which cushion (4) holds the patient. The retaining cushion (4) is connected to a retaining belt (5) which is in turn operatively connected to the catch (10) of an automatic roll-up system (3). The automatic roll-up system itself includes a safety belt (7) which is connected, preferably automatically, to the vehicle floor (11) on loading the stretcher into a supporting device of an ambulance. The relationships are such that in the event of a sudden tensile force in the retaining belt, for example on braking or in a collision with an obstacle, i.e. on exceeding a predetermined deceleration value, the belt locks the automatic roll-up system (3) via its catch (10), so that patient and stretcher are reliably retained. <IMAGE>

Abstract: In screening a fibre suspension, an accept and a reject are tapped off, tapping the reject being controlled by a valve (6). According to the invention, the pressure drop across the screening means is measured, and when this drop exceeds a predetermined first value the valve (6) is opened from a first to a second position and when the pressure drop falls below a second predetermined value or when a given predetermined time has passed the valve is returned to its position prior to opening. In this second position the reject valve (6) is preferably completely open. The accept flow may possibly also be constricted when the reject valve is in the second position.

Abstract: A metallurgical ladle furnace has a ladle for containing the melt, an arcing electrode positioned on the ladle's axis, and a melt electrode in the ladle's lower portion and substantially symmetric with respect to the arcing electrode. DC power applied to the electrodes results in an arc between the arcing electrode and the melt for heating the melt and incidentally causing the melt to stir in vertical directions, the melt moving downwardly in the middle below the arc, upwardly along the walls of the melt and inwardly towards the arc. A DC powered coil surrounds the ladle horizontally at half the ladle's height or higher, around the upper portions of the melt. The field of this coil in cooperation with a DC flow in the melt caused by the current flow between the electrodes, provides a substantially tangential stirring force on the melt which is in addition to the stirring force of the electrode current in the melt. This additional force results in the surface of the melt acquiring a concave shape surrounding the arc and protecting the ladle's wall from the arc flare while increasing the melt's energy absorption from the arc.

Abstract: A new process for the preparation of 6-deoxyanthracyclinones of general formula I:   <IMAGE> I  wherein R represents a hydrogen atom, a hydroxy group or a lower alkoxy group is described. The process provides a total synthesis of the 6-deoxyanthracyclinones of formula I using 1,2,3,6-tetrahydro-phthalate as starting material. The obtained racemic mixture of the compounds of formula I, if desired, can be submitted to optical resolution by the conventional method of conversion to diastereomeric derivatives using a chiral resolving agent. Alternatively, the racemic mixture can be used as such for the condensation with a suitably protected halosugar derivative to obtain alpha glycosidic derivatives of formula XV:    <IMAGE> XV  wherein R1 represents a hydrogen atom or a hydroxy group, one of R2 and R3 represents a hydrogen atom, the other of R2 and R3 represents a hydrogen atom or a hydroxy group and X is a hydrogen atom or a trifluoro acetyl group. The N-trifluoroacetyl 7S:9S and 7R:9R derivatives of the  alpha -glycosides of formula XV can be separated by chromatography on silica gel to obtain, after mild alkaline hydrolisis the wanted 7S:9S  alpha -glycosides (R1=H) as free bases and can eventually be transformed into their corresponding doxorubicin derivatives (R1=OH) by known procedures.

Abstract: Apparatus is disclosed for the distribution of logs into the supply shafts of a plurality of successive grinders from a conveyor line consisting of several belt, chain or other conveyors placed in succession and carrying the logs transversely thereon. The logs are passed from one conveyor to the next and distributed into supply shafts through gaps between the conveyors, which are automatically started for moving the logs on the conveyor line so as to fill the supply shafts. The equipment previously known and used for this purpose has several disadvantages, e.g. the need for sorting of the logs, unnecessary operation of the conveyors, overfilling of the line, etc. The present invention obviates these drawbacks in that the line is provided with sensors for sensing the height of the stack of logs on the conveyor line above each grinder supply shaft, at least two sensors being located above the level of the conveyors so as to control the conveyors adjacent to the shaft, so that they will be started, in motion either simultaneously or separately towards the supply shaft therebetween to ensure that there is always a sufficient supply of logs at the grinder.

Abstract: The invention relates to the glueing method at the manufacturing of fibre bodies, disks, profiles, panels, insulating carpets, packing material etc - according to the dry method. It consists in the fact that the glue is composed of water glass powder, which is mixed with the fibres which have been somewhat moistured before or during the blending and then, together with the fibres are blown into the moulder to be die-pressed to intended fibre body. During the process the glue powder is dissolved in the water present, transcending into plastic or liquid form so as to aggluminate the fibres, whereupon it dries and hardens into a solid bond during the die-pressing. To make the method work satisfactorily the silicatepowder ought to contain some water, bound as gel-liquid or water of crystallization in the alcali silicate. Thus, spray-dried water glass is appropriate as glue powder. To improve the water resistance of the fibre bodies a hardener transcending the alcali silicate to water insoluble silicates can be added. Suitable hardeners are magnesium oxide, zinc oxide or titanium dioxide.
