The invention relates to X-ray diagnostic systems for angiographic examinations. The invention lies in the fact that the passage of the contrast medium is detected by its physiological effects, such as the rise in temperature of the cutaneous tissues, by means of thermocouples C1 to Cn arranged on the body of the patient. The signals from the thermocouples are processed in a device 31 which s...

The process comprises the steps of creating three reference points at an object and taking a tomogram of the object such that the three reference points define a first set of positional data in the tomogram. The object is then non-rigidly placed on a support for operation thereupon by an instrument which is mounted at a flexible arm containing sensors for sensing the movements of an instrument tip...

The invention relates to an electrical solenoid having a pole which ends in a cone and having a tubular yoke, which is opposite said pole, for holding an essentially cylindrical armature, in the case of which the cone is connected to the yoke by means of a material which cannot be magnetised. In order to be able to produce such a magnetic path for electrical solenoids easily by dispensing with the...

The adjustment device uses the calculated cutting force obtained from a number of sensor signals, provided by sensors (7,8) along at least one of the co-operating cutting blades (3,5), as in P4214675.5. The sensors are arranged along a line which is offset from the rotation axis of the cylinder carrying the movable cutting blade (3). Pref. the blade holder (6) for the fixed blade (5) is displaced ...

The outer yarn layers on the circumferential surface of the yarn bobbins, which are wound, for example, on a winding machine or on a spinning machine, run the risk of damage during their subsequent handling and during transport. The risk described is present particularly when these bobbins have to be transported, for example, from a spinning mill to a weaving or knitting mill. It is therefore prop...

There is disclosed a hydro-dynamic separator incorporating a solids interceptor (21) upstream of the overflow (19) for intercepting solid matter above a predetermined size entrained in liquid flowing towards the overflow (19), the solids interceptor (21) comprising: (a) a wall (51) terminating in an upper edge (51a) which constitutes a weir in the flow path of liquid flowing to the overflow (19); ...
