A lithographic projection apparatus includes conduits which supply utilities to components in a vacuum chamber such as object tables and/or associated motors and/or sensors. The conduits are shielded from exposure to the vacuum by conduit conducts having at least the same number of degrees of freedom as their associated object table.

An embodiment of the present invention discloses a highchair with adjustable seat, including a frame and support device, which are connected to the frame and which form a bearing plane for supporting the frame on a floor. The frame includes at least two substantially parallel uprights which in a position of use of the chair protrude at least partly obliquely above the bearing plane. Further, the highchair includes a part adjustable along the uprights, which is provided with an engaging device for engaging the two uprights, wherein the engaging device includes at least one receiving chamber for engaging part of the way round the upright.

The invention relates to a perambulator (1), comprising: a folding frame provided with wheels (9); and a carrying element (5) connectable to the frame for carrying the child to be transported, wherein the frame comprises a substantially horizontally extending undercarriage (2) and a pushing element (3), wherein the pushing element (3) extends as a rigid unit above and as far as the undercarriage (2) and is hindegly connected to the undercarriage and wherein the carrying element is connectable to the pushing element. As a result of these steps, because the cross-shaped part of the frame of the prior art perambulators is omitted, a perambulator is obtained with a much smaller number of components. A perambulator is furthermore obtained of which the appearance is largely determined by the structure of the frame, which is generally seen in a positive light. According to a preferred embodiment the pushing element (3) of the perambulator is provided with two rods (17), each connected hingedly to the undercarriage (2), and with a substantially U-shaped push rod (20) connected thereto for sliding in longitudinal direction, wherein the push rod is lockable with the rods (17) in at least one position.
