摘要:
In order to check hand luggage and other objects carried by persons, control stations are needed, which have a control unit, in particular an X-ray checking unit, a conveyor which extends through the control unit, a depositing point which is arranged ahead of the conveyor, and a removal point which is arranged behind the conveyor, for the objects and having transport tubs which can be placed onto the conveyor. Small objects and items of clothing are placed in the transport tubs and conveyed through the control unit for checking. A return conveyor for the transport tubs is arranged next to or below the conveyor which passes through the control unit, which return conveyor reaches from the removal point behind the conveyor at least as far as into the region of the depositing point ahead of the conveyor.

In an inspection device for inspecting objects for explosives and other items prohibited for travel, particularly in carry-on baggage, a transport shaft (101) where there is little space, has incorporated thereabout radiation sources (10, 20, 30), which generate at least three beams (FX1, FX2, FX3) at which are directed at corresponding linear detectors (11, 21, 31). This transport shaft (101) is extended by incorporation of equipment or system components (3, 4, 40) that are not part of the inspection system (100), or by additional system components (4, 40) being integrated into a housing (103) of the inspection device (100), with a necessary radiation protection for the inspection device in compliance with radiation protection regulations being provided by a shielding (102) placed on or around a piece of equipment or its system components (3) already existing in the transport system (1), ideally in front of the transport shaft (101).

For assembling/disassembling a printed circuit board, a specially shaped spring is to be integrated inside the device. The assembly/disassembly of the printed circuit board in the device is simplified by virtue of the fact that the printed circuit board has to be pressed only against the spring and a fixed supporting part of the device to which the spring is attached. In order to be able to press the printed circuit board, among other things, perpendicularly against the fixed supporting part, the specially designed leg spring is fastened underneath the fixed supporting part. The legs of this spring protrude outward on both sides beyond the top-side of the supporting part. During assembly, the printed circuit board is guided between the top-side and the protruding spring legs. The printed circuit board is fixed by additional supporting parts of the device.

To render a gear arrangement for a transmission as quiet as possible but nevertheless able to handle heavy loads, a first gear made of a first material and a second gear made of a second material sit loosely next to one another on a common shaft. The elasticity of the first gear, preferably made of plastic, is chosen to be greater than that of the second gear, preferably made of metal, while the strength of the second gear is chosen to be greater than that of the first gear. Because the second gear preferably exhibits a slightly smaller toothing than the first gear, only the first gear comes into engagement with another gear in normal operation. As the load increases, the first gear made of plastic yields in the elastic range so that now the second gear made of metal also comes into engagement in order to accept the forces occurring and thereby protect the first gear against overloading and fracture. The gear arrangement is generally suitable for transmissions, for example for planetary transmissions.

A revolving gear arrangement has at least two toothed wheels, which are lubricated with oil or grease and which mesh together in a rolling gap, wherein at least one of them is a revolving gear which is rotatably mounted by means a slip fit joint on a bolt. The bolt-mounted rotating gear is equipped with at least one radial bore, which connects the meshing space of the gear tooth systems with the slip fit joint.

A work station for an X-ray examining apparatus includes a seat-and-standing unit; a monitor disposed in a range of vision of an operator positioned in the seat-and-standing unit; a keyboard; a first device for securing the keyboard to the monitor for pivotal motion of the keyboard relative to the monitor; a second device for adjusting a height position of the seat-and-standing unit; a third device for adjusting a height position of the monitor; and a fourth device for providing for a turning motion of the monitor about a vertical axis, whereby the first, second, third and fourth devices provide the work station with ergonomic properties.
摘要:
An x-ray scanner for inspecting articles moving therethrough, such as on a conveyor, has a frame on which an x-ray source, a collimator for the x-ray beam, and a radiation detector are mounted. The frame resists flexural and torsional stresses so as to maintain the relative positions of the x-ray source, the collimator, and the radiation receiver in the presence of such stresses. The scanner is mounted in a rack in which the frame is seated by a resilient support. The conveyor which is used to move articles through the x-ray beam between the x-ray source and the radiation receiver is supported by the rack, so that mechanical stresses to the conveyor, such as the placement of heavy articles thereon, are not conveyed to the frame, and therefore do not disturb the alignment of the components mounted on the frame, due to the intervention of the resilient support.
