Abstract: Apparatus and method for treating sensitive surfaces, in particular of sculptures Abstract An  apparatus   for treating,   for  example  cleaning, sensitive, in particular highly contoured surfaces such as those of sculptures of wood, plaster, bronze and the like,  comprises  a  mixing  head  (1)  for  mixing  media supplied  to  the  mixing  head  (1)  and  for  spraying  a treatment jet (50) formed therefrom.  The mixing head (1) comprises a mixing chamber (30) into which under pressure a first jet with a liquid treating agent is introduced via a first supply conduit (10) through an inlet (12) and a second jet is introduced, the jet axis (22) of which is inclined at an angle  (?)  to the  jet axis  (11)  of the first jet  and extends  eccentrically thereto.   In  this apparatus the inlet  (12)  for the first jet comprises an inlet opening  (14) which is so formed and/or orientated that the jet axis  (22) of the second jet intersects the first jet.   The treatment of sensitive highly contoured surfaces is carried out according to the invention,  in particular using this apparatus, by means of a treatment jet (50) rotating about its generating jet axis (11)  and containing at least a treating agent liquid before its atomization.

Title: Drop detection method and apparatus
Inventor: YERLIKAYA DENIS Y
IPC: G01V8/14
Filed: 1992-03-31
Abstract: A drop detector system and method are provided for a drop detector of the type including a drop chamber (30) and an electro-optical sensor (40).   The detector system detects drops passing through an optical sensing path between a detector (40) and at least one light source (38). In response to the detection of a drop passing through the optical path, the detector produces an output signal. A capacitator is connected between the detector and an amplifier to block the DC component of the output signal. After amplifica-tion, the signal is passed through a low pass filter to further block signals caused by undesirable factors. The cutoff frequency of the low pass filter is controlled by a microprocessor that controls the pump that pumps liquid from the drop chamber. The detector and light source or sources are ar-ranged to detect drops falling in the drop chamber at virtually any angle and is virtually any ambient light condition.

Title: Flushing device for toilet
Inventor: MARTELL STEVE
IPC: E03D5/10
Filed: 1992-12-23
Abstract: A tank toilet (10) with a ball cock, flap valve (26), or other type of flush valve that is opened manually by lever (30) operating a chain (28) or the like is retrofitted and also made to operate electrically by installation in the tank of the toilet of a float (52) that rides on a substantially vertical shaft (56) that constrains motion of the float. The float (52) is connected by a floating chain (50) to the flush valve. When the flush tank is empty, the float (52) sinks near the bottom of the shaft, where it is held in place by a sear (64) as the tank fills. A solenoid (70) located above the water level is connected to the sear (64) by a lever (66). When the solenoid (70) is energized, the sear (64) is withdrawn, permitting the float (52) to rise on the shaft (56), pull the chain (50) and operate the flush valve (26). The electrically-operated flushing system does not interfere with manual operation of the flushing lever of the toilet.

Patent CA-2116506-A1 (CA)
Inventor: RINKER KARL
IPC: E02F5/00
Filed: 1994-02-25
Abstract: The invention relates to a dredger for the planned taking up of suction material, particularly for removing soil from underground pipes. The dredger has a pneumatic elephant trunk for taking up the suction material and which issues into a storage tank for the sucked up material and to which is connected an exhaust fan. In the storage tank the section material is separated from the suction air flag and is subsequently passed through a filter means positioned between the elephant trunk opening and the exhaust fan. In order to ensure a good separation on the part of the filter means for a long period of time, said filter means is formed by a coarse filter and a fine filter connected to the latter. The coarse filter is formed by a labyrinth or cascade-like flow channel, which is bounded by reciprocally displaced partitions and whose flaw cross-section increases in the flow direction. On the tank bottom can be provided a conveying means by means of which the suction material separated from the air flow can be removed continuously or at intervals from the storage tank.

Title: Automatic ultrasonic localization of targets implanted in a portion of the anatomy
Inventor: LEWIS JUDITH T
IPC: A61B8/00
Filed: 1994-10-20
Abstract: ABSTRACT OF THE DISCLOSURE In a coordinate system defined by a coordinate space digitizer, the location of an implanted symmetric object may automatically be determined based on differences between the characteristic acoustic impedances of at least a portion of an implanted object and one or more materials surrounding that object. An A-mode ultrasound transducer may be attached to a coordinate space digitizer or pointing device such that an attached computer tracks the position and orientation of the ultrasound transducer. The reflected radio-frequency (rf) ultrasound signals may automatically be analyzed along with the transducer position and orientation corresponding to each received rf signal to detect the position of the implanted object. The time delay between received ultrasound echoes is used to compute the depth of the object from the transducer. This allows for an accurate determination of the three-dimensional coordinates of the implanted object.

Title: Bar code incorporated into holographic display
Inventor: KATZ JOSEPH
IPC: G06V30/224
Filed: 1994-06-07
Abstract: In order to improve security for holographic labels which are positioned on a substrate base, a bar code symbol with regions of different light reflective properties is holographically recorded on the base.  The base may be, for example an information card, such as a credit card, a label, or a container for a product.  The bar code symbol can be recorded so that it is visible to the eye in white light (e.g., as a rainbow hologram) or 50 that it requires an appropriate reference beam for reconstruction.  A reading apparatus (e.g., a bar code reader) directs light at the holographic bar code symbol and detects the reflected optical information with a detector such as a CCD array. The reading apparatus can be a stand-alone device or, in the case of a credit card, can be incorporated into a conventional swiper for reading magnetic information on a strip on the card.  A non-holographic bar code symbol can also be provided on or near a holographic display element, e.g., a rainbow hologram.  The bar code can be positioned adjacent the display, or placed in a window within the display, or etched or embossed on the display.  A system is also provided for authenticating a holographic display on an information card such as a credit card.  A display is illuminated and a reflected beam directed at a holographic record which was previously produced from a signal, known to be authentic, and a reference.  The reflected beam is used to reconstruct a reference beam.  A sensor receives the reconstructed reference and it is then determined if the display is authentic.
