  • Patent number: 6387332
    Abstract: A safety system for a gas process or facility for measuring the concentration of a specified gas in an area or chamber and determining whether it is safe to allow access to such area or chamber. In particular, the safety system is adapted for use in a gas sterilization facility having one or more sterilization chambers, wherein the safety system measures the concentration of the sterilizing gas and unlocks the door of the sterilization chamber if the level of the sterilizing gas in the sterilization chamber is below a predetermined limit. The safety system further limits access to the sterilization chamber after a predetermined period of time if the door of the sterilization chamber is not opened due to the possible continued desorption of the sterilizing gas from the articles into the sterilization chamber.

  • Patent number: 5458776
    Abstract: A centrifuge for dewatering a fluent aggregate material such as sand. Sand slurry is conducted into a rotating cylindrical drum which has a perforated lateral wall against which a screen is placed. The drum is oriented with the axis disposed vertically. When the centrifuge operates, centrifugal action slings slurry poured into the drum outwardly. Upon contacting the lateral wall, the slurry builds up. When a certain quantity of the slurry has built up at the bottom or floor of the cylinder, additional material cannot resist migrating upwardly. Thickness of the trapped layer varies, being greater at the floor, near the source of the incoming slurry. This trapped layer forms a bed having an inclined wall. Thickness of the bed at the top of the cylinder is determined by a circumferential, inwardly projecting flange or dam located at the top of the cylindrical drum. The sand bed protects metal parts of the centrifuge from abrasion, and also enables water to diffuse therethrough.

  • Patent number: 5398448
    Abstract: The welding frame (3) of a film-welding device (2) is at the start of its pivoting movement motor-driven in positive manner over a few radians and is then released from the drive, so that only on the basis of its flywheel energy and weight force is it moved on to the locked closed position. Thus, accident risks can be avoided without separate control means, because for stopping the welding frame (5) it is essentially only necessary to dissipate the relatively low flywheel energy.

  • Patent number: 5280754
    Abstract: A system for detecting objects in the path of a power operated, movable door operating in a mass transit vehicle, which would obstruct door closing. The system also includes an integral method for detection of a "free wheeling" door occasioned by failure of the door mechanical drive. Method and apparatus disclosed utilize door handle locating devices such as electrical switches located at predetermined points along the door closure track. A combination of door locations along the closure track centrally define positions signaling either door linkage failure with attendant "free wheeling" door, and/or door obstruction, in each case, the system disclosed prevents train motion until the improper door condition is remedied. The combination provides a reduction in passenger hazards occasioned by train movement with defective operator linkage and/or door obstruction due to trapped passengers or other impediments to door closure.
