Abstract: 1. Agricultural distributor, more especially a sowing machine or fertilizer broadcaster, including adjustable metering members which are driven by at least one wheel, which travels along the ground, or one roller etc , wherein a distance measuring arrangement for determining the distance actually covered is disposed on the distributor, and the metering members are adjustable, in dependence on the instantaneous speed or distance per period of time, which is determined by the distance measuring arrangement, in such a manner that the desired amount for distribution or the number of grains of the seed material or fertilizer to be distributed can be distributed in dependence on the distance covered, characterised in that a displacement transducer (9) is disposed on the wheel which drives the metering members, and in that the values, which are picked-up by the wheel (7) and the distance measuring arrangement (11) either in parallel or during the same period of time, are constantly compared with each other, and in that, if the difference between these two values changes, the adjustable metering members are adjusted in accordance with the change in the difference.

Abstract: Sheet material especially useful in forming wrappers for smokeable articles such as cigarettes that results in reduced sidestream smoke. The sheet is formed by incorporating as a filler in a cellulosic web an amount of high superficial surface area filler in the range generally of from about 5 to 50 percent by weight in the finished sheet. The cellulosic material may be flax fiber or other natural cellulosic fibers conventionally used for such wrappers. Additional fillers may be used up to a total of about 50 percent, and burn modifier salts included. Examples of salts include the sodium or potassium salts of acids such as carbonic, formic, acetic, propionic, malic, lactic, glycolic, citric, tartaric, fumaric, oxalic, malonic, succinic, nitric, and phosphoric. The sheet can be formed by any conventional papermaking method. When such papers are used as cigarette wrappers (4), they effect a reduction of the total particulate matter in sidestream smoke (7) of up to about 70 percent without serious deterioration of other desirable properties. In addition the sheet of the invention provides normal ash (2) appearance in a smoking article.

Abstract: A method and apparatus for producing hollow glass fibers is described in which the glass from a bushing tip and the gas used to provide a lumen in fibers as they are drawn from the tip are fed from passages in the tip sized to provide desired inside to outside diameter in the fibers drawn at the tip. This ratio is established inside of the tip by sizing the gas column having the tip and the glass column leaving the tip such that the ratio of the gas column to glass column is substantially the same ratio desired in the hollow fiber being drawn. Apparatus used to produce this ratio is also shown.

Abstract: Système de régulation de l'écoulement d'un premier fluide à travers une conduite (14). Un organe de distribution (131, 132, 141) isole un région (141) du premier fluide dans la conduite (14) des effets de la pression dans la conduite (14) à l'extérieur de la région (141). L'organe de distribution (131, 132, 141) délivre de manière répétitive des incréments du premier fluide à l'intérieur et à l'extérieur de la région (141). Le fluide de mesure est stocké (13) en communication avec la région (141) de sorte que la distribution d'incréments du premier liquide à l'intérieur ou à l'extérieur de la région (141) provoque une variation de la pression du fluide de mesure. Un organe de déplacement (161, 162) déplace un incrément de volume prédéterminé de fluide de mesure à l'intérieur et à l'extérieur du logement (13) du fluide de mesure, de sorte que le déplacement de l'incrément de volume prédéterminé provoque une variation de la pression du fluide de mesure lorsque la région est isolée par l'organe de distribution (131, 132, 141). Un organe de mesure de la pression (15) mesure les variations de la pression du fluide de mesure. Un organe de commande (81) en communication avec l'organe de mesure de la pression (15), avec l'organe de déplacement (161, 162) et avec l'organe de distribution (131, 132, 141), fait en sorte que ce dernier distribue le premier fluide par incréments en fonction des données provenant de l'organe de mesure de la pression (15), de sorte qu'au moins un des incréments de volume prédéterminés du fluide de mesure déplacé sert de référence pour les incréments de volume du premier fluide émis.

Plusieurs aubes coulissantes (31) sont prévues de façon à former avec le logement (11) et le rotor (23) plusieurs chambres (35) dont le volume varie lors de la rotation relative entre le rotor et le logement. Le rotor (23) peut être déplacé par rapport au logement (11) dans un sens transversal à l'axe de rotation du rotor, afin de faire varier la capacité volumétrique de chaque chambre (35) dans n'importe quelle position de rotation. L'organe servant à déplacer sélectivement le rotor (23) par rapport au logemement de machine (11) comprend des paliers soutenant de façon rotative le rotor et montés dans des logements de palier respectifs. Lesdits logements de palier tournent de façon sélective autour d'un axe excentrique par rapport à l'axe de rotation du rotor, la rotation desdits logements de palier provoquant ainsi le déplacement du rotor par rapport au logement de machine. Est également décrit un ensemble de joints d'étanchéité qui sont disposés sur le rotor et qui servent à préserver l'étanchéité des chambres tout en suivant les déplacements du rotor.

Abstract: The apparatus for improved connection and better use of ion exchangers in treatment processes for industrial water allows a series connection of exchangers so that, after the water from the first exchanger has reached the upper hardness limit which meets the technological requirements, it is not necessary to remove the exchanger from the process for regenerating it, but instead, as a result of the additional installation of valves (1, 2 and 3) on the first exchanger and valves (10, 11 and 12) on the second and the valves (19, 20 and 21) on the third exchanger, it becomes possible to connect the second exchanger in series, so that extreme softening the water within the allowed limits is achieved with reduced loading of the second exchanger, since a part of the water hardness is already reduced in the first exchanger. The water from the first exchanger is not sufficiently softened, so that it cannot be used in the further process because of excessive hardness. However, after passing through the second exchanger, the degree of hardness meets the requirements. The ion exchangers are better utilised, the regeneration process is simpler and the costs of the regeneration and the water consumption for flushing are lower. <IMAGE>

Abstract: A field deflection amplifier (21) generates a field deflection current in a field deflection winding (Lv). An LC resonant circuit (22) is coupled to the deflection winding (Lv) and to an output switching amplifier (Q4). A control circuit (26) switches conductive states of the amplifier (21) at a line rate, 
to excite the LC resonant circuit (22) into provid­ing a line rate correction current for the field deflec­tion winding (Lv). The control circuit (26) varies the modulation envelope of the field deflection current at a field rate in a generally sawtooth manner to provide north-south pincushion correction. When used in con­junction with raster scanning in a square-planar pic­ture tube (SP), the modulation envelope is nonlinearly waveshaped to take into account the aspherical nature of the picture tube faceplate.
