Patent SE-7704295-L (SE)
Inventor: ZANDER R
IPC: G01N21/75
Filed: 1977-04-14
Abstract: To measure the proportions of gases, a reagent solution is used which is specific for the gas whose proportion is to be measured and which discolours in a characteristic manner if the gas in question is present. The sample and the respective reagent solution are fed in and mixed together while maintaining a constant ratio of the amounts fed in or the mixing ratio of the sample and the reagent solution. The concentration of the substance producing the colour (O2, CO or CO2) is determined by measuring the absorbance in a photometer. Such a method makes it possible to carry out the measurement for three different gases in the same way and requires inexpensive chemicals only to be replaced in the process.

Abstract: A soil cultivating implement has an elongated hollow frame portion that houses an eccentric drive transmission to a row of soil working members mounted on respective upwardly extending shafts journalled on the frame portion. The eccentric drive includes two eccentric discs that are mounted out-of-phase on an upwardly extending driving shaft. The eccentrics are pivoted to radial arms on the member shafts of different alternate soil working members by connecting rods so that adjacent members are oscillated in relatively opposite directions. The shafts are located in a plane that is substantially parallel to the longitudinal center line of the frame portion and to the rear of that line and the rods. Each member has three radial arm supports with respective tines, two of the arms being shorter than a third. It is preferred that the longer arm support of alternate members extend rearwardly in the center of its oscillating path and opposite to the direction of the arm supports of adjacent members. The tines are positioned to work overlapping strips of ground.

Abstract: A tensioning device for tightening a band or chain over a load on a vehicle, especially railway wagon, exerts a leverage which varies over the stroke of the device. Manually operated lever arm (16) acts through a lever body (15) which, through a lost- motion linkage (17, 18) drives a transmission element (13) in rotation. The periphery of this is arranged as a cam surface around which runs a chain (12) which is secured to the element (13) at one end and to one arm of a two armed lever (10) at the other. The cam surface gives a progressively increasing mechanical advantage as the arm (16) goes through its stroke. The load-holding band or chain is attached, through a spring loaded shock-absorber known per se, to the other arm of the lever (10). A latch (22) is allowed to fall upon appropriate movement of the body (15) and can catch a nose (13a) in the element (13) when the latter's stroke is complete. The latch is released by opposite movement of the body (15) but only after it has gone through its lost-motion relative to the element (13). <IMAGE>

Abstract: A pressure tapping comprises first valve means selectively operable to be in an open or a closed setting, and second valve means connected to an outlet from the first valve means, which second valve means tends to be closed when fluid pressure acts on it from the said outlet, so that accidental leakage of fluid from the pressure tapping, by failure to close the first valve means when the adapter is removed from the pressure tapping, is less likely.

Abstract: A pressure container forms a shaft gasifier for receiving coarse coal in the form of a coal bed. A burner extends through the pressure container into a chamber therein and produces at least one primary gas jet directed against the coal bed, thereby gasifying the coal and generating a product gas and forming liquid slag. The liquid slag collects in a slag bath tank having an overflow weir over which the collected slag flows and falls freely toward a cooling water bath beneath the chamber. A water jet nozzle directs at least one water jet against the liquid slag as it falls freely between the weir and the cooling water bath. This atomizes the liquid slag, thereby cooling the slag and generating steam. At least a part of the steam is supplied as process steam to the coarse coal.

Abstract: The control ends of two pivotal braking arms have elbowed extensions rotatably mounted in bearings provided on or within an operating pedal. In the active braking position of the pivotal arms, the axes of the elbowed extensions form a V having a downwardly-directed point and the braking ends of the pivotal arms are outwardly displaced with respect to each other on each side of the ski. In the withdrawn position, the braking ends are close together and set back with respect to the sides of the ski. However a tension spring tends to produce a pivotal displacement of the operating pedal with respect to the pivotal arms to an angular position such that the braking ends are spaced at a sufficient distance to pass on each side of the ski.

Abstract: A hand pressing device includes a pressing die in the form of an open-topped rectangular box having a loose perforated bottom plate. The inner walls of the box are smooth. The box is filled with soaked waste paper, particularly old newspapers and a loose pressing plunger with a flat perforated bottom is pressed into the box down to a predetermined penetration depth, whereby water is squeezed out of the soaked paper and escapes both upwards through the perforated bottom of the plunger and downwards through the perforated bottom plate of the box to form a briquette of predetermined dimensions and predetermined density. Upon withdrawal and removal of the pressing plunger and inversion of the box to an upside down position, the briquette thus produced can readily be pressed out of the box by exerting thumb pressure on the loose bottom plate. The side and end faces of the briquette slide along the inner wall of the box with low friction and without being torn. After drying in air, the briquette forms an excellent fuel for fireplaces and stoves.

Abstract: A flash analog-to-digital converter includes 2N comparator circuits for an N bit resolution. Each comparator comprises a summing capacitor which is alternately connected to a reference ladder and to the input signal. The majority of the capacitors are substantially charged and discharged between input potential and reference potential each cycle. The charging/discharging tends to load both the reference ladder and the input signal source. The loading is reduced by including a D.C. biased FET between the input signal source and each summing capacitor. The FET's are biased to condition them to operate as source-followers with the summing capacitors as the load element for at least a portion of the input signal range. Respective ones of the summing capacitors are thereby precluded from charging/discharging over the full input signal excursion which in turn reduces loading on associated circuitry.

Abstract: An absorbent, chemithermomechanical pulp produced from lignocellulosic material with a wood yield above 88%, a low resin content <0.15%, a long fibre content above 70%, a short fibre content below 10% and a shive content below 3. The method for producing the pulp comprises the steps of impregnating, preheating, defibering, and washing the material. The impregnation and preheating of the chips are effected in one and the same vessel over a combined time period of a most 2 minutes, particularly at most 1 minute, preferably at most 0.5 minutes; using a warm impregnating liquid having a temperature of at least 100° C., suitably at least 130° C. and preferably having essentially the same temperature as in the preheating process; and preheating the chips at a temperature of 150-175°C., preferably 160-170° C. Defibering is carried out with an energy input which is at most half of the energy input required for defibering when the preheating and defibering are carried out at 135° C.
