摘要： A spout for a spill-proof beverage container has a side wall defining an outer surface and an inner surface defining a discharge passage. A valve in the discharge passage includes two flanks formed integrally with the side wall and projecting from opposite sides of the inner surface of the spout. The front end faces of the flanks mate with one another along a slit that extends generally parallel to the longer axis of the spout. At least the front portions of the flanks are inclined away from the mouth of the spout such that pressure within the container acts to urge the flanks against one another so as to maintain the slit closed. Deformation of the side wall when the spout is held between the lips of a drinker acts to open the slit and create an opening between the flanks to allow the beverage to be discharged.

摘要： The invention relates to a casting machine for producing a product intended for human consumption from a castable material, in particular a fat material such as chocolate, for example, having a heatable material container for receiving the castable material; at least one nozzle which is in fluid connection with the material container interior, and a pressure source for generating an overpressure in the material container interior. According to the invention, the nozzle has a nozzle orifice or a nozzle constriction, the open cross section or flow cross section of which is flexible. A process according to the invention for producing a product intended for human consumption from a castable material has the following steps: providing a heated castable material in a material container; generating an overpressure in the material container interior; forcing the material through a nozzle in fluid connection with the material container with simultaneous changing of the flow and/or open cross section of the nozzle.

摘要： The present invention presents various novel approaches to solving the problems inherent in measuring biological pressures in high pressure systems. Thus, to protect a pressure transducer exposed to fluid flows at higher pressures than its overpressure rating, a novel valve is used that closes a protected leg in which the transducer is located. The various exemplary embodiments of such valves each have a high pressure input, one or more low pressure inputs, and an output. In operation, when a high pressure fluid flow occurs at a high pressure input, such valves automatically close the low pressure inputs. Alternatively, a novel transducer system is presented, which automatically limits the effective pressure sensed by a transducer to a certain maximum.

摘要： A blood seal having a spring-biased septum is provided for preventing the leakage of blood during the placement and use of vascular catheters and similar devices. The structure of the blood seal includes a housing with an internal channel. A spring-biased septum is placed securely within the channel such that it substantially blocks blood flow through the channel. The spring-biased septum includes an elastic plug having a pre-slit or pre-molded hole and a biasing element disposed about the elastic plug. A needle or other object may be withdrawn through the slit or hole, after which the biasing element forces the hole closed, preventing blood leakage.
