Title: Liquid-cooled hollow anode in an X-ray tube
Inventor: BERGER ENGELBERT
IPC: H01J35/12
Filed: 1983-09-01
Abstract: The conical inner cooling space (13), which is provided in the anode body (2) for base-side cooling of the electron target plate (8), is connected by means of a plurality of cooling channels (19) running in the axial direction to an outer cooling space (16) which encloses the cylindrical anode body (2), including the beam outlet window (11), in an annular shape. The cooling channels (19) are arranged around the anode cavity (5) in order to cool its outer surface, which is heated by electrons scattered at the focus point (12). The inner cooling space (13) and outer cooling space (16) as well as the cooling channels (19) are dimensioned such that a turbulent flow passes through them with a predetermined minimum coolant flow rate. For specified cooling channels (19), the diameter (d) of the anode cavity (5) is selected to be a maximum for absorption of scattered electrons remote from the focus point, and the diameter (D) of the cooled outer surface (17) of the anode body (2) is selected to be a minimum for short thermal-conduction paths. In comparison with known high-power X-ray tubes for a maximum power of approximately 6 kW, an X-ray tube which is equipped with such a hollow anode which is optimised to reduce the focus point temperature can be operated at a power of approximately 9 kW with approximately the same life. <IMAGE>

Title: Crystal oscillator for temperature measurement - counts oscillations during period determined by time base using second quartz crystal
Inventor: WEISE EDGAR
IPC: G01K7/32
Filed: 1986-12-03
Abstract: A quartz crystal (1) whose frequency varies as a linear function of temperature is included in an oscillator circuit (2) which maintains the oscillation. A second quartz crystal whose frequency is independent of temperature in the temperature range under consideration is included in a time base circuit (8). The output is transmitted to a counter (3) with several stages. The counter counts the number of oscillations of the oscillator frequency in the time intervals determined by the time base. A start load circuit (4) fixes the number of oscillations from which the counter starts to count. A preselection memory (6a) preserves this information while a second memory (6b) preserves information from a circuit (5) which signals the division ratio of the counter. The counter gives the temperature reading as a digital word. ADVANTAGE - No effects of adverse signal/noise ratio as in analogue circuit.

Title: Lamellar blind made of light metal
Inventor: ISLER HEINZ
IPC: E06B7/086
Filed: 1978-07-10
Abstract: The blind frame (1) is assembled from two vertical frame legs (1.1) and two horizontal frame legs (1.2 and 1.3) and consists of rectangular hollow profiled bars. The lamellae (2) are double-walled hollow profiled bars which are designed round on the narrow sides. The lamellae (2) are mounted rotatably on pins (8) which on the other hand are likewise mounted rotatably in bearing rails (9). The bearing rails (9) are pressed against the lamella ends (2.2) by springs (10) which are accommodated between the bearing rails (9) and the vertical frame legs (1.1), as a result of which a frictional resistance arises in the rotation points, which prevents the lamellae (2) rotating without mechanical influence. A rotation of the lamellae (2) is achieved when the inner rail (4) of two which form an adjustment rail (3, 4) and are mounted approximately in the central axis of the blind is displaced. The inner rail (4) is connected to each lamella by rotatable couplings and at the same time fastened slidably in the outer rail (3). The outer rail (3) can, by pushing downwards, engage on the blind frame (1) with two transverse bolts (11.1 and 11.2) in two tabs (7.1 and 7.2) on the horizontal legs (1.2 and 1.3) and thus prevent any rotation of the lamellae (2). <IMAGE>

Title: Device for determining the hit position in a target
Inventor: FISCHER ERICH
IPC: F41J5/06
Filed: 1978-11-22
Abstract: In the case of the device for determining the hit position in a target, the target has a group of acoustic sensors (a-d) which are arranged in the plane of the target and occupy a defined position with respect to a reference co-ordinate system. In order to determine the hit position, these sensors (a-d) have connected downstream of them an electronic evaluation device having a computer (R) which calculates the hit position on the basis of the time interval between the arrival of a shock wave at the various sensors (a-d). In order that changes in the speed of sound propagation within the target do not lead to incorrect indications, the group has at least one more sensor than is necessary for being able to calculate the hit position when the speed of sound propagation is known. <IMAGE>
