摘要:
The present invention relates to a nut cracker (100). The nut cracker (100) includes a stationary die (1) and a movable die (11). The movable die (11) is designed as a falling weight. The falling weight is designed and arranged to fall down towards the stationary die (1) due to gravity to crack the nut.

A sensor element containing a porous layer is provided for detecting a physical magnitude of a measured gas, such as for determining the concentration of a gas component of an exhaust gas of an internal combustion engine. The porous layer includes pores of a first pore type whose diameters correspond to at least half the layer thickness of the porous layer.

The present invention provides a method of manufacturing metal air cell systems. The method includes a thermoset molding step to integrate the cell structure with necessary cell components. This method offers reliable, stable structure and, most importantly, good bonding with porous components (e.g., air cathode, charging cathode) to prevent potential leakage.

A method of making a multi-port nozzle having multiple tubular ports for dispensing liquids is provided. The method involves introducing a molten polymer composition into a connector device mounted on a die plate. The connector device has a plurality of plastic tubes projecting therefrom. The molten composition surrounds and bonds to the tubes. Subsequently, the connector device having tubes attached thereto can be removed from the die plate. The resulting connector nozzle can be used to discharge liquids in various applications such as industrial coating operations.
摘要:
A spiral-shaped lamp (10) is used for disk manufacturing processes, such as curing of coating or bonding, to provide uniform intensity of UV energy to the circular disk without requiring relative motion between the disk and the lamp during the curing process.
摘要:
A medical transfer or storage device for delivery or storage of a medicament, drug or vaccine, wherein a first component, preferably the major component, is formed of a cyclic olefin polymer, and a second component in contact with the first component is formed of a second polymer which does not chemically interact with the cyclic olefin polymeric component at elevated temperatures, including sterilization. More specifically, the relative energy distance Ra/Ro of the polymer selected for the second component relative to the cyclic olefin polymer is greater than 0.75 and the molecular weight of the second polymer is at least 5,000 to prevent adhesion of the second component to the cyclic olefin component and stress cracking at elevated temperatures. The most preferred embodiment is a syringe assembly having a cyclic olefin polymeric barrel and a resilient stopper formed of the second polymer.
摘要:
The invention discloses a method by which a fluid heat reactive resin system is formulated below the melting point of the resin. This permits the application of coatings and the formation of shapes and powders from the fluid heat reactive system. Liquefied gases are used to solvate resins so that curing agents, hardeners, pigments and flow control agents, and especially curing agents which are too reactive to be mixed with the resins above the melting point of the resins may be dispersed in the resins. After dispersion, the fluid heat reactive resin system remains in a deformable state under ambient conditions for a transient processing time. The transient processing time is established and maintained by the inclusion of plasticizers and high boiling solvents in the heat reactive resin system.
摘要:
A preferred process comprises providing a pre-formed, substantially transparent window for a cover of an electrical-energy meter, and molding the cover from a molten resin that, when solidified, is substantially opaque. Molding the cover from a molten resin comprises causing a portion of the molten resin to contact a periphery of the window and allowing the portion of the molten resin to cool and thereby solidify so that the portion of the molten resin, upon solidifying, is molded over the periphery of the window and thereby seals and secures the window to the cover.
