Abstract: A hydraulic lifting-lowering-system for a working table, a couch or lying furniture or another heavy object allows the height level or position to be frequently adjusted or changed. The system includes a predetermined amount of hydraulic fluid, a hydraulic fluid accumulator, the fluid pressure of which on the hydraulic fluid side is adjustable, a single acting hydraulic cylinder with two end caps, a piston pressure chamber and a piston rod which, via a piston rod sealing ring, extends sealingly out through the one end cap of the cylinder. The piston pressure chamber is pressure fluid connected to the hydraulic fluid side of the accumulator. The hydraulic cylinder is of the plunger piston type, and the cylindric tube of the hydraulic cylinder is slideably and telescopically mounted in a cylindrical guiding tube, which surrounds the piston rod in its entire length and is rigidly secured to the one end of the piston rod via a cross plate or similar construction part. Thus, a simple, stable and reliable system is achieved without the need for crank handles, and by which new system the force applied from the plunger piston rod will be essentially constant in all positions of the piston rod at a given load, seeing that the operational manual force necessary for height adjustment of the heavy object becomes low.

Abstract: The invention provides an efficient way to store multiple tickets on smart cards. According to the present invention, a ticket (20) comprises a validation count field (26) for registering by way of a validation count the number of times the ticket may be used. Preferably, the validation count is lowered each time the ticket is validated, the validation being effected by writing validation data in the validation field (22) of the ticket. In this way a single ticket can thus be used as a multiple ticket, thus saving memory space. The validation count is also effective in limiting the number of tickets validated, thus limiting the extent of possible fraud. <IMAGE>

Abstract: A method for manufacturing a resin-impregnated endless belt structure having a texturized outer surface requires the use of a support structure, either a cylindrical mandrel or a pair of carrying rolls, having a texturized surface. An endless, permeable base structure is placed about the support structure, which is adapted to place the base structure under tension in a longitudinal direction. A polymeric resin material is dispensed onto the outside of the base structure on the support structure. The polymeric resin material totally impregnates the base structure and passes therethrough to coat the texturized surface of the support structure. A layer of polymeric resin material is also built up on the outside of the base structure. The polymeric resin material is then cured, and may be ground to provide the layer of polymeric resin material with a smooth, uniform surface, and the belt structure thus obtained is removed from the support structure. The belt structure is finally turned inside out, placing an impression of the texturized surface of the support structure on the outside of the belt structure, that texturized surface having a plurality of indentations for the temporary storage of water pressed from a fibrous web in a press nip.

Abstract: A method for purifying a minority constituent and concentrating it in a majority constituent of a gas mixture that also contains one or more other minority constituent(s) employs (i) a selective permeation step, (ii) next, a purification step, and (iii) finally a concentration step. In the selective permeation step, an initial gas mixture is passed through a membrane to yield a gas mixture that is enriched in the first minority constituent. In the purifying step, the first minority constituent is absorbed by a solid adsorbent which has a strong affinity for the first minority constituent, then following an elution step, a gas mixture that contains essentially only the majority constituent and the first minority constituent is formed. Finally, in the concentrating step, one or more successive adsorption and elution operations on a solid adsorbent, which has a strong specific affinity for the first minority constituent, are employed until an end gas mixture having the desired concentration of the majority constituent and the first minority constituent is obtained. This end gas mixture is highly enriched in the first minority constituent relative to the initial gas mixture. The procedure is particularly suited for detecting rare gases, e.g., xenon, and especially for detecting the natural and radioactive species in the atmosphere. The procedure can be employed in association with nuclear spectrometry to detect and monitor the presence of trace gases in the environment around nuclear installations.

Title: Method and device for measuring the flowing speed of fluids
Inventor: Schäfer Burghard
IPC: G01F1/66
Filed: 2005-06-01
Abstract: The invention relates to a method which is used to measure the flowing speed of fluids according to the transit time difference method (?T = T2 - T1), in addition to a suitable measuring circuit. In a first measuring step, an ultrasonic measuring path (11) which is arranged between two ultrasonic transducers (10, 12) is transversed in the forward direction. An emitting transducer (10) is excited with a limited number of excitation impulses (burst 1) in order to emit an ultrasonic wave train. A receiving transducer (12) receives the ultrasonic wave train as an analog signal train (W1) which is subsequently digitalised in order to form a pulse train (D1) and is counted in an impulse counter (4). The period of time extending between a determined pulse of the excitation impulse (burst 1) and an n-th pulse of the pulse train (D1) is the first period of time (T1). Subsequently, the ultrasonic measuring path (11) is transversed by means of a defined number of excitation pulses (burst 2), which have the same frequency, in the reverse direction. The wave train received by the transducer (10) as an analog signal train (W2) is digitalised in order to form a pulse train (D2). The impulse counter (4) remains inactive for the duration of a door time (TGate) which is connected to the first period of time (T1). The period of time between a defined pulse of the second excitation impulse (Burst 2) and the first pulse of the pulse train (D2), which is detected after activation of the impulse counter (4), is the second period of time (T2). The flowing speed (v) of the fluid can be calculated from the time difference (?T) between the first and the second period of time (T1, T2).
