Patent CA-2001608-A1 (CA)
IPC: A61N2/02
Filed: 1989-10-26
Abstract: The  present  invention  relates  to  a  magnetic  field generating apparatus for medical treatment with a timer which comprises a timer for setting a time of operation,  and is configurated in a manner that displaying operation of the residual time by a numeric display 50 is changed-over blink-ing operation of predetermined numerals when a temperature sensor 54 disposed on a magnetic field generator 20 detects an unusual temperature,  and the blinking operation by the numeric display 50 is changed-over to the displaying opera-tion of the residual  time when the temperature sensor 54 detects clearance of the unusual temperature.   An unusual temperature of the magnetic field generating apparatus for medical treatment can be informed to the user by this blink-ing operation,  and therefore a special alarm component such as a conventional alarm buzzer or alarm lamp can be dispensed with,  and thereby a reduction in the number of parts and a reduction in the cost can be realized.

Title: Radiation scintillation detector
Inventor: RADTKE JEFFREY L
IPC: G01T1/203
Filed: 1989-11-10
Abstract: RADIATION SCINTILLATION DETECTOR                  ABSTRACT OF THE DISCLOSURE     A radiation scintillation detector which is particularly suited for X-ray detection is formed as a solid body of rotation about a central axis of a scintillator medium.  The body includes at least one internal reflective surface, and at least one substantially planar surface through which the light is substantially transmitted to a photomultiplier tube.  The curvilinear axial cross-section of the internal reflective surface is formed such that substantially any light originating from an area in proximity to a point of most probable emission within the body and intersecting the internal reflective surface is totally reflected internally.  The photomultiplier tubes will receive most of the light emitted, by virtue of the decreasing taper of each internal reflective surface as it approaches the planar surface.  A detector comprising two portions, which are joined integrally back-to-back to each other, and which each include an internal reflective surface, internally reflects substantially all photons striking the reflective surface to the photomultiplier tubes.

IPC: B22D31/00
Filed: 1990-07-17
Abstract: ABSTRACT         With a cleaning device that uses high-voltage discharges in liquids, it is possible to safely clean even clusters of preci-sion castings if a tubular processing chamber serves as shock wave reflector and the position of the component and of the electrode are variable.  Casting elements encrusted both with thin ceramic layers and with more ductile deposits are safely cleaned after they are lowered into the tubular chamber with sealable apertures on both sides, and after shock waves have been generated via the electrode positoned in the chamber.  The tubular configuration of the chamber, which is preferably positioned endless, makes it pos-sible in particular to utilize the reflection waves to clean the individual components.  By way of a hoist, the component configur-ed as a cluster as well as any other configured component is passed by the electrode, turned, and if necessary swivelled in order to thus ensure a uniform and rapid cleaning.  The chamber itself is filled with water in order to conduct the shock waves, whereby water and residue are continually diverted in the base area while new water is added at the top, preferably the recycled and purified water.
