Abstract: A brake mechanism for a beam trolley on a beam has a body member on the beam trolley adjacent the beam. The body member has a recess and axially aligned bores and a rotatable lateral pin extends through the aligned bores. The lateral pin has a rotatable elongate cam portion extending across the recess, and a brake pad is in the recess adjacent to the beam and abutting the cam portion. A handle is connected to the lateral pin for rotating the pin and the cam portion to displace the brake pad against the beam. The brake pad frictionally secures the beam trolley on the beam and locks the rotatable cam in place. Rounded end portions on opposite ends of the lateral pin and sleeve-like bushings between the axially aligned bores and rounded end portions permit rotation of the cam portion by the handle.

Abstract: The invention in one variation is a pressure vessel having a pair of hemispheres with a wall and a circular edge, a pair of sealing elements, and an intervening mounting plate with circular groove on both sides of the plate. The hemispheres are mounted on opposite sides of the plate. Each groove has an sealing element and the circular edge. A seal is formed between the plate and a hemisphere when the hemisphere is pressed against the sealing element. Pressure can be generated by creating a partial vacuum in the sealed hemispheres or by using clamps. When exposed to higher pressures, such as when the vessel is used underwater, the pressure on the hemispheres is conveyed to the sealing element forming an even tighter seal. The vessel has interface connections that enable communication to and from devices mounted inside. The vessels are modular and can be ganged to provide redundancy or different functions.

Abstract: The present invention is a self contained, portable security case or container. The case is secure in its locked condition by locks which are preferably operated by an electronic key. The electronic key can be programmed to open the case or container dependent upon various different conditions, for example, location, time, identification of operator, etc. In addition to the electronic key, a biometric identification device can be employed. The exterior of the case or container is made from different materials which are impermeable and resistant to heat, drilling and ballistic impact. A GPS type of location device located within the case enables the case to be tracked from remote locations.

Abstract: The present invention provides a standardized mechanical interface (SMIF) reticle pod that is configured to provide a controlled environment for supporting a reticle wherein the controlled environment is maintained substantially free of crystal growth causing contaminants. Accordingly, there is provided a layered filter with filter elements capable of filtering particulates and adsorbing gaseous contaminants. The filter has an inwardly facing face generally planar shaped with a surface area that is substantially half or more of the area of the reticle face. The inwardly facing face is placed in close proximity to the reticle patterned surface and has an area that is a significant fraction of the reticle patterned surface area. The SMIF pod is also provided with a purge system configured to inject a very dry gas within the controlled environment to flush the controlled environment of contaminants as well as to regenerate the filter.

Abstract: The present invention is directed towards a container for transporting of valuables in a first compartment; particularly towards a container having a second compartment containing an alarm system. The alarm system includes an air bladder, i.e. airbag, for instantaneous and rapid deployment when triggered by a remote activator or other devices present on the container. After being triggered the air bladder inflates to a volume much greater than the second compartment and the container, such that the thief cannot easily transport the container into a car or through a doorway, or at the very least without being noticed.

Abstract: A wafer carrier for carrying a plurality of axially aligned thin circular wafers. The wafer carrier has a framework portion formed from a pair of end members connected by a plurality of side support members. A pair of opposing sidewall assemblies is positioned between the pair of end members, and is attached to at least one side support member. Each sidewall assembly has a plurality of shelves defining a plurality of slots for receiving a wafer. The sidewall assemblies are formed from a plurality of stacked together individual shelf members. Each shelf member has a body portion with an upper surface and a lower surface. The lower surface has a plurality of pegs which are positioned to be received by a plurality of apertures formed in the upper surface of an immediately adjacent individual shelf member.
