  • Patent number: 10920934
    Abstract: A mobile dispenser may be used to at least partially fill hydrogen tanks of fuel cell-powered vehicles. The dispenser uses a purely mechanical control of the fill using an orifice plate across which a pressure differential is maintained through use of a backpressure regulator whose reference pressure is controlled by a differential pressure regulator. Because it does need or use electrical power, it may be used in situations where no electrical power is available or convenient.

  • Patent number: 7212896
    Abstract: A vehicle control system (10) including a vehicle motion control subsystem (12) that has an input receiving an intended driving demand (14) and a plurality of coordinator subsystems (16) for coordinating actuators of the vehicle. The vehicle motion control subsystem (12) communicates with the coordinator subsystems (16) to determine whether a single coordinator subsystem (16) can carry out the intended driving demand (14). The vehicle motion control subsystem (12) will distribute demand signals among one or more of the coordinator subsystems (16) to allow the vehicle to implement the intended driving demand (14).

  • Publication number: 20050156070
    Abstract: A wear part (5) for detachable mounting on a supporting part in an impact-type multi-action crusher is at least partly manufactured by hot isostatic pressing. The wear part (5) has a body (19) for mounting of the wear part (5) on the supporting part and a crushing layer (20) which is attached to the body (19) and which is adapted to be brought, during operation of the crusher, into repeated contact with a raw material that is to be crushed. The body (19) is made of a substance which is easy to machine to narrow tolerances, and the crushing layer (20) is made of a material (27, 28) of high abrasive resistance. In a method of manufacturing the above wear part (5), the following steps are carried out: introducing at least one powder material (27, 28) into a capsule, degassing and sealing the capsule, subjecting the material (27, 28) in the capsule to hot isostatic pressing to form a crushing layer (20), and then after treatment of the wear part (5).

  • Publication number: 20030144646
    Abstract: The invention relates to a method and an apparatus for collecting and transporting liquids, for example blood, into one or more closed packages, for instance so called transfer bags (11, 12), or alternatively, directly transfering the blood into another liquid system, for instance a heart-lung machine, without any admixture of air or any other gas or gas mixture. The blood is collected without contact by human hand and without contamination of the blood and under sterile conditions. The apparatus comprises a suction nozzle (4) for sucking up the liquid or a liquid/air/gas mixture, a suction hose (5) for directing the liquid to a defoaming separator (7) for separating air from the liquid, and a recipient (8) in which the deacrated liquid is filtered and collected. When a certain volume has been collected, the liquid is directed without introducing air into said closed packages (11, 12) or communicated to another liquid system.

  • Patent number: 6468807
    Abstract: The invention relates to a method for carrying out mixing in a thin liquid layer, which is arranged between essentially parallel walls at a capillary distance from each other. The mixing is carried out by subjecting the walls to a motion essentially in the plane of the liquid layer, balancing the motion against the capillary force exerted by the walls on the liquid, and selecting the interface between the liquid layer and the surrounding medium so that it functions as an elastic membrane. The invention also concerns a cuvette which is designed for mixing according to the method.

  • Patent number: 6333007
    Abstract: A photometer for determining the transmission of a liquid sample in a microcuvette (7, 20, 22) has a cavity for a capillary layer of the liquid sample with a free liquid surface extended transversely of the principal plane of the cavity. The cavity is initially prepared with a reagent to achieve a reaction, which affects the transmission of the liquid sample for indicating its contents of a predetermined substance. The photometer has a holder (6) for the microcuvette and measuring means (9, 10) for measuring the transmission of a bundle of rays directed towards the microcuvette. The cuvette holder (6) is mounted on bearings for vibration in a direction having a component, which extends in the plane of the free liquid surface and is parallel with the principal plane of the cavity, thereby achieving a mixing to accelerate the dissolution and the reaction.

  • Patent number: 5387204
    Abstract: A method and a device designed to suck and to convey various types of liquids through a suction hose (45) and at the same time does (4) an additive to the liquid in an accurate proportion to the amount of the sucked liquid. A liquid or a liquid/air/gas mixture is sucked by means of a suction nozzle (2,45), which is influenced by a certain pressure P2 with a moderate suction action, and is passed through the suction hose (45). A dosage device (4), which includes a flexible dosage container (20), which is enclosed in a rigid casing (21), and which is influenced by a certain relatively lower pressure P3 (providing a stronger suction action) than the pressure in the suction hose (45), is connected directly to the suction hose (45).

  • Patent number: 4386261
    Abstract: A gas heating apparatus for divers comprises an electrical heating cartridge (1) which is replacably inserted with close fit into a gilled pipe (2) having an external helical flange (3). The pipe (2) is surrounded by a mantle (4) which is connected to a hood (8) with an outlet nozzle (9). The hood (8) and the pipe (2) is with a substantial play inserted into a pressure vessel (5,6,10). The vessel has an end cap (6) through which the hood nozzle (9) extends. The end cap (6) has also an inlet nozzle (7) for cold gas, which thus can flow through the gap (12) between the mantle (4) and the vessel wall (5) to the pipe end opposite the hood (8), and from there the gas flows in a helical path through a channel section defined by the flange (3) and the mantle (4) to the outlet nozzle (9) and is heated during passage along said path. The vessel also comprises an openable sealable compartment (19), wherein an electrical connection between the cartridge (1) and a power supply cable can be sealed from the ambient water.
