Abstract: The present invention relates to a pre-filled disposable injection device and a needle cannula in combination. The prefilled disposable injection device (1) is made from a housing (2) containing a non-exchangeable cartridge (10) for storing a liquid drug sufficient for a number of injections. The proximal end of the pre-filled injection device (1) carries the dose setting button (3) and the distal end carries the needle cannula (20) having a lumen (21) through which the settable dose is expelled. The distal end (23) of the needle cannula (20) is covered by a telescopic needle covering shield (30) which shield (30) can operate between a first position covering the tip (24) of the needle cannula (20) and a second retracted position allowing an injection to be performed.

Abstract: The invention relates to an indirectly heated fluidized bed dryer (1) for drying moist, fine-grained bulk materials. The fluidized bed dryer (1) comprises a housing (2) with a gas-injection bottom (6) with built-in heat exchanger parts extending above the gas-injection bottom (6) and at least one discharge device, provided below the gas-injection bottom (60), for the dried bulk material. The fluidized bed dryer (1) according to the invention is distinguished in that the usable flow cross section of the housing (2) increases in the region of the built-in heat exchanger parts while the cross-sectional area of the housing remains the same over the height of the built-in heat exchanger parts in the direction of flow of the fluidizing medium. In this way, an inadmissible expansion of the stationary fluidized bed is reliably prevented.

Abstract: The protective covering for a marquee consists of a casing (22) carrying a winding shaft and having a discharge opening extending along the entire length of the casing, which can be closed tightly by a top flap (42) and a bottom flap (46). Top flap (42) is pivoted upward during the discharge of the marquee by its outer tube (14) counter to the force of gravity and following the re-entry of the marquee drops back into its closed position. Bottom flap (46) drops during the discharge of the marquee by its own specific gravity into open position and is drawn back into closed position at the end of the re-entry movement by means of closing levers (76) remaining in the movement path of the outer tube. The quite small top flap (42) cleans off the marquee, but loads it with only a slight weight. The pressure of the outer tube (14) against the closing levers (76) holds flaps (42, 46) dependably closed tightly in the re-entry position/closed position.
