Abstract: Airborne transmitted pathogens, including severe acute respiratory coronavirus 2 (SARS-CoV-2) and similar infectious diseases, often spread through close contact between humans. One common form of transmission is that of saliva droplets that suspend in the air and are subsequently inhaled by another human, leading to pathogen transmission. The application is based on formulated confections (such as lozenges, cough drops, gum, candy, buccal films, and other consumable products) and/or medicinal drugs that alter fluid properties and/or reduce quantity of the saliva. As a result, the modified fluid properties of the saliva mitigates droplet breakup, resulting in larger droplets that travel shorter distances before quickly falling to a ground surface. The saliva reduction reduces the amount of saliva. As a result, the formulated confections reduce the prevalence of airborne transmitted pathogens (such as SARS-CoV-2) with a lesser/thickening saliva.

Abstract: A balloon inflating device includes a gas mixing device fluidly connecting a supply of pressurized lighter-than-air (LTA) gas and a supply of a second gas to a balloon interface nozzle via a gas shut-off valve. The gas mixing device includes an outer pipe including a closed first end, an inner chamber, an inner pipe that projects through the closed first end of the outer pipe into the inner chamber, a first fluidic inlet and an outlet port. The inner pipe includes a second fluidic inlet into the inner chamber. The second fluidic inlet fluidly connects to the supply of LTA gas. The first fluidic inlet is proximal to the closed first end and fluidly connects to the supply of the second gas. A second end of the outer pipe fluidly connects to the outlet port. The outlet port fluidly connects via the gas shut-off valve to the balloon interface nozzle.

Abstract: A seal for movable structural components, like piston rods or shafts, includes a carrier body made of thermoplastic material and a sealing member locked to said carrier body and made of polytetrafluoroethylene (PTFE) material. A form-lock connection is achieved by an undercut which is formed permanently in the sealing member and filled with plastic material of the carrier body.

Abstract: A seal for movable structural components, such as piston rods or shafts, includes a carrier body made of plastics and a sealing member made of polytetrafluoroethylene (PTFE) material and bonded to the carrier body. A plastic material may be mixed with the PTFE and fused to the plastic carrier body during injection molding.
