20210331007 · 2021-10-28 ·

A filter cartridge includes a first end component, a second end component, and filter media positioned between the first end component and the second end component is provided. The filter media maintains separation between the first end component and the second end component to allow for air flow through the filter media. The first end component includes at least two receptors and the second end component includes at least one protrusion configured to interface with the at least two receptors to hold the first end component and the second end component in the same relative position with respect to each other when a torque is applied to the filter cartridge. The cartridge is assembled together by adhesive binding the filter media to the first end component and the second end component.

A method for controlling display of information on a display device includes storing information corresponding to a broadcast program guide. When a signal is received based on activation of a specific key while the first broadcast program is displayed on a screen, information on the first broadcast program and information on a second program to be broadcast after the first broadcast program is detected. The first broadcast program is then displayed in a first region of the screen simultaneously with the information on the first broadcast program and the information on the second broadcast program in a second region of the screen.

Filter element with an oblique sealing plane

A filter element for a filter for filtration of a fluid is insertable along an insertion direction into the filter. The filter element is provided with a filter medium to be flowed through along a main flow direction. The filter element has a clean side and a raw side. A sealing surface surrounds the filter medium, wherein the sealing surface, interacting with a filter housing of the filter when the filter element is in an installed state in the filter housing, separates the clean side from the raw side. A support edge exerts a force on the sealing surface by interacting with the filter housing of the filter when the filter element is in the installed state in the filter housing. The sealing surface and the support edge are positioned at an acute angle relative to each other.
