Abstract: Syringe/conduit combination with a syringe part (1) and a conduit part (2). The parts have a male slip fitting (4) and a female slip fitting (5) for press fitted connection. The syringe part (1) has a hollow barrel (22) and a plunger (23) inserted into the barrel (22). The plunger (23) and the hollow barrel (22) have abutments (25, 27) defining a maximally inserted position of the plunger (23). The male slip fitting (4) fits in the female slip fitting (5) such that the male slip fitting (4) is at an axial distance of less than 0.1 mm from an internal end of the female slip fitting (5). The plunger (23) in its maximally inserted position is then at an axial distance from an opposite one of the slip fittings (5) that is equal to or less than the axial distance between the male slip fitting (4) and the internal end (9) of the female slip fitting (5).

Abstract: A vehicle, provided with: at least an optical passage situated at a vehicle exterior for passing on optical signals; a number of elongate optical signal guides, extending between said passage and at least an optical signal processing unit situated in the vehicle, wherein the optical processing unit is provided with a transmitter for transmission of diverging optical signals; wherein an optical system is arranged to pass on light between the signal processing unit and proximal ends of at least a number of the optical signal guides, wherein the optical system comprises a collimator to collimate optical signals coming from the transmitter.

Abstract: Vehicle, provided with: —at least an optical passage (1) situated at a vehicle exterior for passing on optical signals (S1, S2); —at least an elongate optical signal guide (2), extending between said passage (1) and at least an optical signal processing unit (U) situated in the vehicle. The invention further provides a system for transmitting and receiving optical signals, as well as methods.

Abstract: Mattresses for cots and infant beds include a mattress core having first and second faces. Each face is overlayered by a comfort layer and a cover layer. The mattress core includes a relatively firm core layer and a relatively soft core layer. Suitably, the firm core layer includes an array of helical springs or a foamed polymeric or fibrous material.

Abstract: A lithographic projection apparatus with a chuck in which a dielectric element of the electrostatic chuck has a specific resistivity of at least 1016 ?cm so that once the potential difference between electrodes of the chuck is removed the force on the article to be clamped reduces below a predetermined minimum level quickly. The dielectric element also has a coefficient of thermal expansion of less than 0.02×10?6K?1. A method of manufacturing a chuck includes joining a first glass ceramic element with a second glass element with an electrode therebetween in which a current is passed through the second glass element.

Abstract: A lithographic projection apparatus with a chuck in which a dielectric element of the electrostatic chuck has a specific resistivity of at least 1016 SE cm so that once the potential difference between electrodes of the chuck is removed the force on the article to be clamped reduces below a predetermined minimum level quickly. The dielectric element also has a coefficient of thermal expansion of less than 0.02×10−6K−1. A method of manufacturing a chuck includes joining a first glass ceramic element with a second glass element with an electrode therebetween in which a current is passed through the second glass element.
