Latest Patents

One of Gerritsen's latest inventions is a mortar transport apparatus. This apparatus consists of a rotor with cylindrical mortar transport chambers, which is positioned between stationary sealing plates and driven by a motor. The design includes a feed hopper above the rotor that fills the transport chambers through a filling hole in the upper sealing plate. Additionally, a blow-off chamber is located beneath the lower sealing plate, allowing for the connection of a transport hose. The blow-off chamber is designed to be filled via a mortar discharge opening, and it features a duct for supplying air under pressure to facilitate the pneumatic transport of mortar through the hose. Notably, the slit-shaped opening for air supply is formed by a series of separate spray openings arranged in a semi-circular pattern, enhancing the efficiency of the mortar transport process.

Another significant patent by Gerritsen involves a cathode ray tube that includes means for vertically extending the spot. This invention features an electron gun within an evacuated envelope that generates an electron beam focused on a display screen. A four-pole magnetic structure is integrated around the focusing lens to extend the spot in the vertical direction, thereby reducing phosphor saturation, particularly in blue projection tubes.
