The arrangement includes a support structure configured to hold an image detector at a first end and an X-ray source at a second end, with a connection line in between on which an Iso-centre is located. The support structure connects to a primary supporting beam in a first pivotable connection point; the primary supporting beam connects to a secondary supporting beam in a second pivotable connection point; and the secondary supporting beam connects to a mounting arrangement in a third pivotable connection point. A rhombus shape is defined by: (i) a connection line between the first and second pivotable connection points; (ii) a connection line between the second and third pivotable connection points; (iii) a connection line between the third pivotable connection point and the Iso-centre; and (iv) a connection line between the Iso-centre and the first pivotable connection point.

Abstract: The present invention relates to the mobility of an X-ray system. In order to provide X-ray imaging systems with improved mobility, a base (10) for a mobile X-ray imaging system is provided that comprises a carriage (12), a mounting structure (14) mounted to the carriage and a wheel base (16) with a wheel arrangement (18) of at least three wheels (20) mounted to the carriage, and a wheel controller (15). The mounting structure is configured to movably hold an X-ray imaging device. The carriage comprises a first end portion (22) and an opposite second end portion (24). The first end portion is configured as a front end arrangeable closer to an object during X-ray imaging, and the second end portion is configured as a rear end arrangeable away from an object during X-ray imaging. The first end portion and the opposite second end portion are arranged along a longitudinal center line (17) of the base.

Abstract: The present invention relates to mobile X-ray imaging. In order to provide a mobile display system for X-ray imaging with improved space requirements, a mobile medical imaging viewing station (14) is provided. The mobile medical imaging viewing station comprises a mobile support stand (30), a display device (32) movably mounted to the support stand, and a docking arrangement (34). The display device is movable to provide adapted positioning of the display device in relation to the mobile support stand. The docking arrangement comprises a docking interface attached to the support stand. The docking arrangement is configured to interact with a counter-interface of a mobile medical X-ray imaging station for docking the mobile medical imaging viewing station to a mobile X-ray imaging station for at least transport purposes. The mobile support stand is provided with wheels (38) that are retractable when the docking to a mobile medical X-ray imaging station is provided.

Abstract: A process (10) for synthesising hydrocarbons includes feeding a gaseous feedstock (18) comprising hydrogen and carbon monoxide, into a first Fischer-Tropsch reaction stage (12) which is a three-phase low temperature catalytic Fischer-Tropsch reaction stage, and allowing the hydrogen and carbon monoxide partially to react catalytically in the first reaction stage (12) to form hydrocarbons. At least a portion of a tail gas (32) which includes unreacted hydrogen and carbon monoxide obtained from the first reaction stage, is fed into a second Fischer-Tropsch reaction stage (42) which is a two-phase high temperature catalytic Fischer-Tropsch reaction stage. The hydrogen and carbon monoxide are allowed at least partially to react catalytically in the second reaction stage (42) to form gaseous hydrocarbons.

Abstract: A device for processing a disc-shaped substrate, which device comprises a plurality of stations arranged in side-by-side relationship, whereby the substrate can be moved into and out of the device in a first station and be subjected to a processing step in a second station, said device furthermore being provided with a transport mechanism for transporting the substrate between the various stations, whereby each station comprises two side walls and an intermediate plate extending between said side walls, which intermediate plate is provided with a guide section extending between the sides of said side walls that face away from each other, whereby stations positioned adjacently to each other are attached together by means of the side walls facing each other and whereby said stations are positioned with respect to each other in such a manner that the intermediate plates and the guide sections are in line, whereby the transport mechanism is capable of movement between the various stations over said guide sections

Abstract: A two-head recorder in which information is read from recording tracks which are substantially parallel to each other and which make an angle with the longitudinal axis of a tape-like recording medium. The recorder comprises two heads which are each mounted on a transducer for moving the head as a function of tracking signals for the two heads which appear alternately so that the two heads are alternately centered relative to the recording track. The tracking signals are also applied to a tape speed control circuit in order to control the speed of the tape-like recording medium depending upon the average value of the tracking signals.

Abstract: A phase comparison circuit for comparing first and second pulse trains applied to first and second inputs (1 and 2) respectively, comprises a sawtooth signal generator (11,3) which is phase-locked to the first pulse train (V.sub.A) by means of a frequency control loop comprising a first sampling circuit (4,5) and an amplifier (12). The output signal of the sawtooth generator is sampled when each pulse occurs in the second pulse train (V.sub.B) by means of a second sampling circuit (8,9). In order that a phase difference of zero between the two pulse trains can be accurately determined, whatever their actual repetition frequency, the output signal of the arrangement is formed by means of a differential amplifier (10) as the difference between the output signals of the two sampling circuits.

Abstract: A magnetic tape drive arrangement without pressure roller, having a signal generator which generates a signal T, derived from the capstan motor current and the capstan speed. The is proportional to the instantaneous torque exerted on the magnetic tape by the capstan, which signal T controls the supply and/or take-up motors in such a way that this signal is minimized, so that a slip-free magnetic-tape drive without pressure roller is possible.

Abstract: A servo system for controlling the position of a magnetic reading head relative to the center of a selected information track. During recording a long-wave positioning signal is recorded below the data signal in the tracks. Upon reading out, the head not only reads the information of the selected track but, as result of cross-talk, also the positioning signals of the adjacent tracks. After filtering out and processing the positioning signals, a control signal for controlling the head is obtained.
