Abstract: A low pressure drop device for personal protection against toxic industrial chemicals and chemical warfare agents has a flexible polymer hood impermeable to toxic challenge molecules, a neck seal for sealing the hood about the neck, a half mask for connection to a canister and a low pressure drop canister for chemical protection. The canister contains carbon monoliths of 5- 40 mm diameter, length 1-3 cm, open area 30-60%, surface area ?700 m2/g optionally activated to >30 wt % weight loss and optionally impregnated with metallic additives and/or triethylene diamine. The monoliths have square channels of size 100-2000 ?m and wall thickness 100-2000 ?m. It also contains a resiliently flexible closed cell foam with holes slightly smaller than the monoliths so that flow through the canister is through the monoliths.

Abstract: The nature of a volume hologram limits its use in security and sensing applications. Accordingly, a volume hologram segregated into a first and second region recording a first and second image, respectively, and wherein the second region is responsive to stimulus while the first region is protected physically from stimulus is provided. Also provided is a volume hologram with a functional cover disposed thereon to regulate how the volume hologram interacts with the stimulus when in the presence of stimulus. A volume hologram with a removable cover disposed thereon to permit a first recorded image to be viewed, to protect the volume hologram from physical damage, to prevent the volume hologram from interacting with the stimulus, and to be removed, thereby permitting the volume hologram to interact with the stimulus is provided as well. In these ways, the usability of volume holograms in security and sensing applications is increased.

Abstract: A jar cap is formed with an orifice through its flat top surface and an adhesive coated closure tab is placed over the orifice. The closure tab has a non-adhesive portion for being grasped. The jar is closed with the cap and vacuum sealed. When the cap is to be removed, the non-adhesive portion of the closure tab is grasped and the closure tab is pulled off the orifice, allowing ambient air to enter the jar and relieve the vacuum so as to make the removal of the cap easier.

Abstract: Apparatus and method for facilitating the opening of vacuum-sealed jars by punching a hole through the jar cap and removing the implement to relieve the vacuum. The apparatus has a pin mounted on a plunger that is supported on a compression spring. The compression spring serves to raise the pin and plunger after use. A magnetic pad is affixed to a lower surface of the apparatus for attaching to a jar cap during use.
