Vehicle safety devices, heat shields used in such devices and related methods are provided. The heat shield for use in vehicle airbags can include a woven base substrate and a needlepunched nonwoven substrate comprising silicon-containing fibers. The needlepunched nonwoven can be needlepunched to the woven base substrate such that, when the heat shield is positioned within an interior space of an airbag, the needlepunched nonwoven substrate faces apertures of an inflator within the airbag.

Provided is a monitoring system for a milling facility, which includes a plurality of grinders including roll mills for grinding a material to be milled and sifting machines for sifting, according to grain size, the material to be milled as ground by the roll mills; and a plurality of pulverizers including roll mills for pulverizing the material to be milled and sifting machines for sifting, according to grain size, the material to be milled as pulverized by the roll mills. The material to be milled is milled by each of the grinders and pulverizers. A plurality of flow rate measuring devices are provided on respective flow paths for product flours discharged from the respective sifting machines in the respective grinders and pulverizers, and a monitoring device capable of monitoring presence or absence of an abnormality based on measurement results on respective flow rates of the product flours is provided.

A grain pipe valve assembly maintains a desired level of flow restriction through a grain pipe. The assembly includes a valve couplable to a downspout. The valve is positionable proximate a lower end of the downspout. The valve has a swivel gate selectively extendable into the downspout wherein the swivel gate inhibits flow of grain through the downspout. A sensor is couplable to the downspout in spaced relationship to the valve towards the upper end of the downspout to detect when backflow of grain reaches a predetermined level in the downspout. The sensor is operationally coupled to the valve wherein the swivel gate is controlled and extended into the downspout to maintain backflow of grain to the predetermined level in the downspout.

The present invention provides a coffee capsule machine, comprises a housing, a grinding unit disposed on the housing and including a grinding container, and an arcuate powder compacting unit. The arcuate powder compacting unit comprises an arcuate powder compacting channel extending upward from bottom to top, a tamping hammer slidably disposed within the arcuate powder compacting channel, and a driving mechanism configured to drive the tamping hammer to slide along the arcuate powder compacting channel. The arcuate powder compacting channel comprises, from top to bottom, a driving end, a transition section, and a powder outlet end. The powder outlet end is located below the grinding container, and the transition section is arranged to bypass the grinding container. This configuration results in a more compact internal layout within the housing, thereby reducing the overall size of the coffee capsule machine and lowering packaging and transportation costs.
