Title: Sealing device for hydraulic fluid channel - has at least two spheres, preventing abrasive particles from interference fit of first sphere reaching hydraulic fluid
Inventor: PFEIFFER BERND
IPC: F16L55/10
Filed: 1990-12-07
Abstract: The hydraulic fluid channel (6) has an obstruction, whereby a first sphere (1) works in conjunction with at least one other sphere (2).

Title: Rotary drum bearing race securing system - incorporates mating faces on race and claws inclined towards rotation axis
Inventor: SCHEPP MARTIN
IPC: F27B7/22
Filed: 1990-12-13
Abstract: The system secures bearing races to a rotary drum, e.g. a tubular furnace, each race being pressed by its bore face against the drum by claws at the sides.

Title: Measuring keying ratio of clock signals - quantising signal to be evaluated in series binary form several times by triggering flip=flop by noise generator
Inventor: BRINKER KLAUS
IPC: G01R29/027
Filed: 1991-01-07
Abstract: The clock signal with a ratio, theta, is serially binary quantised n-times, each time quasi-randomly. To realise the random variable, X, the probability at which theta (1-theta) assumes the valve 1(phi) is ascertained. The relative frequency of the realisation of X=1 (X=theta) with increasing trail range, n, converges in probability against theta (1-theta). The signal to be evaluated (f(t)) is applied to the data input of a bistable flip-flop (FF) strobed via its clock inplut (C) by a pseudo random bit sequence (phi R) produced by a binary noise generator (RG). USE/ADVANTAGE - High resolution. Can evaluate h.f. pulse signals. Short time measurements.

Title: Process and appts. for min. start=up loss in cold-fed extruder - comprises adjustable throttle controlled by pressure in feed zone, avoiding incomplete melting and porosity and start=up without die
Inventor: MEIER GUENTER
IPC: B29C48/92
Filed: 1991-02-04
Abstract: Process and equipment for minimising start-up loss with extruder cold-fed with rubber or thermoplastic, in which a throttle unit (16), consisting of at least ten fluid-operated rams (5) arranged in a plane circumferentially around the barrel (1) and projecting radially inward between a gap in the screw flight (3), is controlled by a computer (9) which compares with a pre-set value, the signal from a pressure sensor (10) upstream of the throttle (16) in the extruder feed zone. When the pre-set value is reached, the rams are gradually withdrawn. ADVANTAGE - By creating a back pressure on the feed material during start-up, inhomogeneous and porous product, resulting from trapped air and incompletely melted particles, is avoided, reducing waste of scrap material. Process makes unnecessary a preliminary start-up without a die for safety reasons, making even greater material saving and saving prodn. time wasted in subsequent fitting of die. The additional residence time, homogenising and mixing in the feed zone due to back pressure from the throttle permits sealable material to be extruded from very early in the operation.

Title: Glidant contg. X=ray contrast agent - useful in facilitating and controlling catheter
Inventor: SACHSE HANS E PROF DR MED
IPC: A61K49/04
Filed: 1991-07-31
Abstract: A glidant (A) contg. an X-ray contrast agent for insertion into hollow organs of the body. The contrast agent is pref. loxitalamic acid, meglumine salt, sodium amidotrizoate and meglumine amidotrizoate. In catheterisation, e.g, of the ureter, the catheter tip is introduced and (A) is sprayed through the catheter until it exits from the tip and forms a depot at the tip region of the catheter. Upon further insertion, this depot lubricates the tip and external surface of the catheter and thus facilitates its passage and simultaneously applies the X-ray contast agent to the inner lumen of the ureter. As a result of the latter, the movement of the catheter can be followed on a screen. USE/ADVANTAGE - (A) is used in conjunction with the introduction of catheters and similar instruments and provides not only a lubricating effect, but also enables the introduction to be controlled and documented. (A) avoids the problems associated with conventional introduction of X-ray contrast fluids using a plastic tube. Further (A) can be readily adapted to the required viscosity, which is usually low in the case of pure X-ray contrast agents.

Title: Determining radiation dosage in hollow organ, esp. rectum - determining coordinates of points on surface of multiple detector probe and performing spatial transformation
Inventor: GUENTHER ROBERT DR
IPC: A61N5/10
Filed: 1991-11-21
Abstract: The coordinate triplets of the radiation detector positions (6,7,8,9,10) in a multi-detector probe (3) are converted from an applicator (12) based reference frame (x,y,z) to a probe reference frame (x',y',z') in which the curved probe (3) lies in a plane y' = constant.

Using these variables, the tip radius (5) of (4), the diameter of (3), the distance (4) to the first detector (6) and the transform (x,y,z) to (x',y',z'), the coordinates of points on (3) are determined. Further, according to the irradiation plan, the close rate at these points are determined, and by simulation calculation, the maximum dose at the surface of the hollow organ is found. An inverse square law is used for the radiation intensity due to the applicator sources. USE - For gynaecological afterloading therapy with stepped radiative source.
