Abstract: The invention relates to a high-voltage generator which is proportioned so as to realize a particularly low weight in combination with a high output power and is suitable notably for use in rotating X-ray systems such as computed tomography apparatus. To this end, the high-voltage generator is provided with a hybrid insulation which is formed as far as possible by a high resistance foam (30 to 35) and an insulating liquid (50). The foam is shaped and arranged in such a manner that there are formed channels (40 to 45) wherethrough the insulating liquid (50) can flow in areas requiring a discharge of heat or an electric strength stronger than can be endured by the high- resistance foam alone.

Abstract: The power supply stage is used to supply the X-ray tube (4) via a HV transformer (3) with 2 groups of primary and secondary windings (16, 31; 26, 32) which are wound on the same transformer core. The coupling factor between the primary windings (16, 26) of the different winding groups is less than the coupling factor between the primary and secondary windings of the same winding group. Each of the primary windings is coupled to a respective current regulator (1, 2) with a fixed operating frequency and an individually regulated pulse ratio, providing overlapping voltage pulses.

Abstract: A method for manufacturing a molded structure includes the provisioning of a first mixture which includes microparticles and a liquid-phase mixture of resin and curing agent. The first mixture is centrifuged to extract a volume of the liquid-phase resin and curing agent mixture from the first mixture, the centrifuging process resulting in the formation of a liquid-phase matrix of microparticles which are at least partially- coated with liquid-phase resin and curing agent. The liquid-phase matrix of at least partially coated microparticles is cured to form a solid-phase matrix of microparticles, thereby providing the molded structure.

Abstract: The invention relates to a method of manufacturing a hard foam that can be used as a high-voltage insulating material in high-voltage generators and other high-voltage applications. The invention further relates to a device for carrying out such a method. In accordance with the method, a filling material (5) comprising substantially ball-shaped, preferably hollow particles is fed to a container (1). Subsequently, the filling material (5) is compressed by means of a high pressure (Pi). Subsequently, a liquid binder material is injected under high pressure (P2) into the compressed filling material (5) via an injection orifice (7) and is hardened. Preferably the filling material (5) comprises a mixture of relatively large particles having a diameter between 30 and 100 µm and of relatively small particles having a diameter between 5 and 30 µm. The method results in a hard foam having a relatively high density of the ball- shaped particles and a good binding between the ball-shaped parts. As a result, the hard foam is very light, has a high mechanical stability, and has good insulating properties.

Abstract: The tube (2) has a protective casing (1) with a heating convertor connected to the cathode (3). The transformer has two primary coils (14,16) and two secondary coils (15,17) in a coaxial arrangement. Preferably both sets of coils are wound on a support (10) constituted by the high-voltage connection (10), or on the neck (5) of the tube itself. The tube provides compensation for disturbances of the tube and for stray field losses from the heating transformer.

Abstract: The invention relates to an X-ray tube which includes a device for at least substantially protecting an object to be examined against the incidence of undesirable X-rays (E) which can be produced notably by the decay of a residual or surplus charge present in a high-voltage circuit after an X-ray exposure. To this end there is provided at least one device ( 341, 342 ) for deflecting and/or defocusing the electron beam (E) produced by the residual and/or surplus charge in such a manner that at least it is not incident to a significant extent on a region ( 22 ) of an anode ( 2 ) wherefrom X-rays excited thereby are directed towards an object to be examined.
