The guide plates being arranged radially, wherein at least one guide plate has a first section starting from a connection point and a second section starting from the connection point. Therein, the first section extends axially in a first direction, the second section extending axially in the opposite second direction. Therein the first section is designed to taper radially and/or the second section is designed to taper radially.

Abstract: A diffusion pump is provided that includes a housing and a boiling chamber connected to the housing. The boiling chamber has a heating element. The housing has a nozzle that is connected to the boiling chamber. The housing also has a condenser is arranged at an internal surface, where the condenser has a cooling system. The boiling chamber is thermally isolated from the condenser by an isolator. The cooling system is at least partially a water cooling system and is connected to the heating element via a heat pump such that heat from the condenser is supplied to the heating element.

Abstract: A diffusion pump, in particular an energy-efficient diffusion pump comprising a housing and a boiling chamber connected to the housing. In the area of the boiling chamber a heating element is arranged. Further, a nozzle is arranged in the housing which nozzle is connected to the boiling chamber. In the area of the nozzle a condenser is arranged at an internal surface of the housing, wherein in the area of the condenser a cooling system for cooling the condenser is provided. The boiling chamber is thermally isolated from the condenser by an isolator. Alternatively or additionally, the cooling system of the condenser is at least partially a water cooling system. Alternatively or additionally, the cooling system of the condenser is connected to the heating element via a heat pump such that heat from the condenser is supplied to the heating element.

Abstract: The invention concerns a method of controlling a flight obstacle lighting arrangement, wherein a receiver co-operates with a switching device for the flight obstacle lighting arrangement. According to the invention it is proposed that the receiver upon receiving a first predetermined signal controls the switching device in such a way that the flight obstacle lighting arrangement is switched off.

Abstract: The invention relates to waste material removal devices and related assemblies and methods. In certain aspects of the invention, a machining tool has a waste material removal device, which comprises a suction slide for carrying out a movement in a translational direction (x). The suction slide includes a suction arm support and a suction arm, and the suction arm is fastened pivotably on the suction arm support. In certain aspects of the invention, a waste material removal device has a suction arm having a suction opening and a separating device for separating solid waste material parts according to their weight arranged at the suction opening. The suction opening is oriented at an angle between 10° and 170° to a longitudinal axis of the suction arm.

Abstract: The present invention relates to improved methods and systems for manufacturing optical storage media from which information can be read out and/or into which information can be recorded by means of a beam of electromagnetic radiation. Furthermore, the present invention relates to an improved optical storage medium which can be obtained with the method and system of the present invention. The optical storage medium comprises various layers (1, 5, 7), wherein at least two of them are bonded by means of a pressure sensitive adhesive layer (4). At least the adhesive layer is cut by means of a laser beam so that the disadvantages of mechanical cutting tools are overcome.

Abstract: A pair of closed loop chains running in parallelism have uniformly spaced apart paddles on them for transporting an article such as a pad between each paddle to a pad ejection station. A shaft orbits about an axis which is parallel to the direction in which the paddle conveyor is moving. The shaft carries a plurality of ejector rods which are mounted on a sleeve that is slidable reversibly axially on the orbiting shaft. After the orbiting rods collectively eject a series of pads from the paddles, the shaft continues its orbital movement until it reaches the back side of the pads again. While the rods are passing through the paddles to eject the number of pads composing a stack, the sleeve on the orbiting shaft is translated axially in the same direction and at the same speed as the paddle conveyor is moving. The sleeve is shifted by having a cam follower thereon come into contact with a stationary cam when the rods begin their passage through the spaces between the paddles.

Abstract: Apparatus for turning pads through an angle of 90.degree. about an axis perpendicular to their plane as they are orbited with a drum from a pad pickup station to a pad transfer station. The drum has a plurality of circumferentially spaced apart supports inside of it. A hollow shaft extends radially out of each support and has a vacuum pickup shoe on it. A pinion is fastened concentrically to the hollow shaft and a gear in the support turns the pinion. A cam follower engages in the groove of a stationary circular cam. As the drum rotates the cam follower arrives in a part of the cam groove which turns the gear and results in the hollow shaft and the vacuum shoe being turned through an angle of 90.degree. as the shoe is orbited from the pad pickup station to the pad transfer station. Flexible tubes connect ports in the base of the drum to the hollow vacuum shaft.

Abstract: A vertically extending stripper bar is manipulated to strip a stack of articles from a conveyor while the conveyor is carrying the articles downwardly at high speed. A carriage is mounted for being vertically movable. A pneumatic cylinder is coupled to the carriage. The stripper bar is supported on horizontal guide rods which slide in the vertically movable carriage. A pneumatic cylinder moves the stripper bar horizontally in and out relative to the conveyor. When the correct number of articles has accumulated next to the bar, a stripping cycle is initiated. This involves activating one pneumatic cylinder which pushes the stripper bar horizontally across the path of the downwardly moving articles. A gear rack is mounted to the vertically movable carriage and it is engaged by a gear which begins to drive the carriage and stripper bar downwardly at the same speed that the articles are moving downwardly at the instant the stripper bar begins to move horizontally.
