  • Publication number: 20240203676
    Abstract: In an embodiment, a multi-switch contactor assembly includes an array of two or more switches, each switch comprising a moveable contact and a fixed contact; wherein the moveable contact is configured to contact a first end of the fixed contact in a closed switch state; and wherein the moveable contact and the fixed contact are oriented such that current passing between the moveable contact and the fixed contact induces an electromagnetic field that acts on the moveable contact in the direction of the first end of the fixed contact; and an actuator assembly configured to actuate each movable contact simultaneously, the actuator assembly including a shaft, wherein the respective switch states of the two or more switches are changed in dependence upon rotation of the shaft.

  • Patent number: 9549974
    Abstract: The invention relates to the field of vaccines against microbial infections and especially bacterial vaccines, in particular to pneumococcal vaccines. More in particular, the invention relates to means and methods to identify, select and isolate a vaccine component for passive and/or active immunization against a microorganism that can be killed by opsonophagocytic cells. The invention relates to a method to identify an opsonophagocytosis inducing antigen as a vaccine component for immunization against a microorganism. The invention describes three pneumococcal proteins SlrA, IgA1 proteinase, and PsaA, and their use as a vaccine component with or without PpmA. The invention also discloses the use of antibodies against said proteins for passive immunization and diagnosis.

  • Patent number: 7337657
    Abstract: A pressure glow plug for a diesel engine has a glow plug body 2 for being inserted into a cylinder of the diesel engine, a heating rod 1 that is arranged in the glow plug body 2 and a pressure sensor 9 that is arranged between the heating rod 1 and the glow plug body 2 in such a way that the pressure in the combustion chamber of the cylinder that is transmitted by the heating rod 1 influences the pressure sensor 9. The heating rod 1 is arranged in the glow plug body 2 such that it can be displaced in an axially sliding fashion, namely by a corresponding sliding element, for example, a membrane 7 or seals 3.
