Abstract: A glass breaking tool includes an elongate plunger which has a pointed head (i.e. ram member) at one end. The plunger, including the pointed head, is normally arranged within a housing. A contact block may be secured to the plunger at the second end thereof A coil spring may surround the plunger and may extend between the contact block at the second end of the plunger and a portion of the housing which may be substantially adjacent the first end of the plunger near the pointed head portion. The plunger is adapted for movement from its rest position where the pointed head is arranged within the housing to an extended position where the pointed head extends outside of the housing. Suction cups or adhesive is used to attach the tool to the portion of glass to be broken.

Abstract: A casino gaming table provides a smoke-free environment for the casino operator by discharging an air curtain or air barrier of purified filtered air. The gaming table includes a filter assembly which withdraws smoke contaminated air from ashtrays and smoking patrons who are playing the casino game. The purified filtered air is discharged adjacent the casino operator to provide a breathing zone free of cigarette smoke and related pollutants.

Abstract: A self-contained, portable air purification device is designed to continuously cleanse airborne particulates which include infectious respiratory organisms such as tuberculosis bacilla. Contaminated air is drawn into the device about 360.degree. from the breathing or working zone to capture the airborne infectious respiratory organisms. The airborne microbial particulates are extracted by a high efficiency particulate air filter capable of eliminating 99.97% of all airborne particles that are 0.3 microns in size or larger. The filter is permanently sealed within a filter cube that is disposable in its entirety for replacement purposes. The filter cube is releasably secured within the device to provide a leak-free air tight seal eliminating any potential air bypass. Clean filtered air is discharged at the bottom of the device in a 360.degree.
