20220152430 | DOOR BREACHER - A door breaching device includes a longitudinal chassis having a first extremity, a piston assembly with a piston rod adapted for linear displacement within a piston chamber, a hydraulic pump operatively connected to the piston assembly, and a two-part head assembly with a fixed jaw attached to the first extremity of the longitudinal chassis and a moveable jaw operatively connected to an end of the piston rod proximate to the first extremity. When the device is in a rest position, the piston rod is in a retracted position within the piston chamber to allow portions of the fixed jaw and the moveable jaw to fit between a first surface and a second surface. Upon actuation of the door breaching device, the piston rod is linearly displaced from the retracted position and the movable jaw applies a force to increase a distance between the first surface and the second surface. | 2022-05-19 |
20220152431 | Hood For Powered Air Purifying Respirator - A respiratory device for covering a head of a wearer can comprise a head engagement element. A hood can define an interior and a rim. The hood can comprise a rim that is configured to bias against the head of the wearer to inhibit air communication therebetween. At least a portion of the hood can be transparent. A hose fitting can be operatively coupled to the hood to provide air therethrough into the interior of the hood. The hood can be configured to be releasably coupled to the head engagement element at a plurality of positions. The plurality of positions can comprise a forward position and a rear position that is spaced from the forward position by at least one inch along an anteroposterior adjustment axis. | 2022-05-19 |
20220152432 | FACE MASK - An improved face mask includes a plastic face shield that is formed from a material with sufficient flexibility to confirm to the face of the user. The face mask has a first, distal, open end configured to cover the mouth and nose of the associated user, and a second, proximal end having an enlarged opening therethrough. A cage is secured to and extends outwardly from the proximal end of the face shield. A filter is mounted to the face mask via the cage. An amplifier and microphone is secured to the cage. | 2022-05-19 |
20220152433 | REUSABLE FILTERING FACE MASK - A reusable, protective face mask has two detachable filter trays that attach on each side of the mask, a soft elastomeric face seal, and straps to go around the user's head. Exhalations and inhalations can pass through the same filter material. The filter trays can accept arbitrary filter media. A forward-facing port can be used to increase speech intelligibility by transmitting sound through a diaphragm without a prohibitive amount of distortion. Manufacture of the mask is facilitated because the mask body and the other mask components can be produced by injection molding. Decontamination and sterilization are facilitated because the mask can be fully disassembled. | 2022-05-19 |
