Abstract: A plasma reactor, in which particulate matter is caused to nteract with low temperature plasma (i.e. below 100,000 K) comprises spaced stationary electrode structures 2, 11 of which at least one is annular, between which an arcorarcs7 is established by a power supply which may include a thyristor (SCR) 9. The arc is pulsated and caused to orbit or circulate round the or each annular electrode structure to form a conical plasma zone between the electrodes, while particulate solids are introduced through inlets 5 to enterthe plasma zone and interact with the plasma therein. Extended dwell periods and highly effective interaction are brought about by circulation and pulsation of the arc and a high particle population density.The arc can be circulated at high speed by electrical means, for example by sequential energization of plasma torches 1 in an annular array or of the segments 8 of a segmental anode, or by electromagnetic circulation of the arc attachment round an annular cathode or round a segmental anode with the help of coils 10 fitted between the segments. Examplesof reactions that can be efficiently conducted by this method include the reduction of metal ores, beneficiation of low grade chromite ores, recovery of energy values from low grade carbonaceous matter such as colliery wastes and the formation of pozzolanic material and cements from siliceous minerals.

Abstract: Les agents d'impression ("toners") utilises pour l'impression dans des procedes electro-photographiques tels que la xerographie ou l'impression au laser sont extraits du papier de reproduction. Dans le procede, le papier est reduit en pate pour former une boue aqueuse. Le "toner" est extrait du papier avec un systeme double constitue par un collecteur et une substance chimique de recuperation. Les meilleurs collecteurs ont des parametres de solubilite semblables aux "toners" de telle sorte que le "toner" soit adouci legerement soluble dans le collecteur. Ceux-ci comprennent le polystyrene, le chlorure de polyvinyle et les polyacrylates p.ex. les methacrylates de polymethyle. D'autres collecteurs moins satisfaisants sont le polyurethane et le polypropylene. Le collecteur se presente sous la forme de pastilles, granules ou feuilles. Le collecteur specifique depend des substances chimiques specifiques du "toner". La substance chimique de recuperation doit remplir plusieurs conditions. Elle devrait etre sensiblement insoluble dans l'eau. Elle devrait avoir un point de fusion identique ou inferieur au point de ramollissement approximatif du "toner" ou du recuperateur. Elle devrait etre un alcool primaire aliphatique sature, un melange de tels alcools, un alcool primaire aliphatique non sature, un melange de tels alcools non satures, un alcool secondaire sature, un hydrocarbure primaire aliphatique sature, un melange de tels hydrocarbures, ou un melange d'hydrocarbure et d'alcool. Le procede peut etre applique a une temperature egale ou superieure au point de fusion de la substance chimique de recuperation, et a une temperature a laquelle le "toner" se ramollit generalement entre 38 et 75 C.

Abstract: In a roof for a house heated by solar energy, an air collection room (6) is provided for heating air by heat absorption from the solar energy radiated onto the roof. In order that the external appearance of the house is not impaired by collectors and none of the heat produced in the house is lost, the air collection room (6), which is arranged under the roof ridge (2) and covered with moulded plates (3) which let light radiation through towards the inside, contains a solar collector made of special tubular collectors (11) with a closed fluid circuit system and is connected to the inside of the house via air supply channels and outgoing air channels (9, 16). The tubular collectors (11) consist in each case of a transparent tube and, mounted coaxially therein and flowed through by the fluid, a blackened tube. Air channels can be divided in half in the longitudinal direction by a film and flowed through in the halves (211, 212) by air of differing temperature, so that they can serve as fresh air heat exchangers. <IMAGE>

Abstract: Roll for a double two-high reversing mill for rolling down preliminary sections or semi-finished products, which has adjacent live and blind grooves, the blind groove/s permitting passage of the rolling stock between a continuously driven pair of rolls counter to the rolling direction of the latter. In order to provide the rolling stock with additional guidance in the region of the blind groove, the roll is of multi-part design and has a core shaft (30) to which at least one roll ring (31, 32) is connected in a manner fixed in terms of rotation, which ring, with its groove cut (24, 28), forms a live groove, whereas the adjacent blind groove (25, 27) is cut into a blind-groove ring (33, 34) freely rotatable on the core shaft. As regards their cuts, the exchangeable blind-groove rings can be designed in such a way that they are capable of guiding the rolling stock coming from an aligned live groove (24 and 28 respectively) of an upstream pair of rolls, in that, due to contact with the rolling stock, the blind-groove rings take on the direction of rotation corresponding to the rolling direction. <IMAGE>

Abstract: A seat suspension system, which includes a height adjustment valve for positioning a seat at a desired height in response to manual positioning of a height adjustment lever by controlling the amount of hydraulic fluid supplied to a cylinder having a piston therein coupled to the seat, provides damping of vertical motion of the seat by an accumulator coupled to the cylinder via a conduit so as to receive the hydraulic fluid from the cylinder and two different valves disposed in the conduit. A manually adjustable flow control valve has an adjustable orifice within the conduit for providing the seat with a nominal amount of damping. The damping of the suspension system is increased beyond the nominal amount in response to seat velocity in a downward direction by the second valve which responds to the pressure of hydraulic fluid flowing from the cylinder to the accumulator so as to restrict the flow of the fluid by an amount dependent upon the fluid pressure and thereby the rate of change of downward movement of the seat. At the same time the second valve is generally unresponsive to the pressure of fluid flowing in an opposite direction from the accumulator to the cylinder so as to be unidirectional in nature.

Due to this feature, forces (F,; µF 1 ) are introduced which are circumferential directed along the ball (3'). in case of upcoming instability, forces (F 2 ; µF 2 ) in radial direction between the cage pockets (5) and balls (3) are generated which urge the cage (4) to take in its stable position.
