Abstract: Separator wheel for an air separator which at its periphery has channels through which separation air loaded with fine material flows into the separator wheel from the outside to the inside. The separation air loaded with fine material is discharged from the separator wheel in axial direction. Channels in axially different radial planes have different angles (.alpha.) of incline to the radial direction of the separator wheel. The angle of incline (.alpha.) of the channels near the outflow end of the separator wheel is greater than the angle of incline (.alpha.) of the channels remote from the outflow end. The incident flow of separation air which is loaded with fine material toward the outer port of channels is influenced by the slope of the channels relative to the radial direction of the separator wheel. The channels are aligned in axially different radial planes at different angles (.alpha.) to the radial direction of separator wheel. This results in more uniform separation properties.

Abstract: A liquid discharging method which employs a liquid discharging head consisting of a liquid discharging port, a bubble generating region where the bubble generates in the liquid and a movable member that can move between a first position and a second position which is located at a point farther from the bubble generating region compared with the first position, wherein the movable member moves from the first position to the second position by the pressure of the bubble generated by the bubble generating energy in the bubble generating region, and at the same time the bubble expands farther toward the downstream direction compared with the upstream direction by the displacement of the movable member in order to discharge the liquid out of the liquid discharging port by the liquid discharging energy applied to such liquid.  The movable member has its free end in the downstream side with respect to its fulcrum and the liquid is discharged by applying the discharging energy corresponding to a saturation domain where the amount of the liquid to be discharged out of the liquid discharging port is substantially saturated in accordance with the increase of the discharging energy.

Abstract: A turnable lock (10) operable with driver (15u) and tumbler (15l) pins when positioned by a key (16) at a shear line (18) in which shearable assembly pins (15a) are assembled in the lock (10) and thereafter sheared to form such driver (15u) and tumbler (15l) pins for operation thereon. Each assembly pin (15a) is selectively weakened at a plurality of locations (17) which correspond with notched depth heights of the family of keys (16) capable of insertion in the keyhole. Such weakening is controlled so that pin shearing can be accomplished by application of rotational or linear forces applied to any part of the lock (10) except the key (16). When linear forces are used the tumbler or plug (13) may be indexed to employ a driver pin (15u) as a plug lock.

Title: Modulated backscatter sensor system
Inventor: SHOBER R ANTHONY
IPC: A61B5/024
Filed: 1997-10-27
Granted: 2002-12-10
Abstract: In accordance with the present invention, a radio communication system includes an Interrogator for generating and transmitting a radio signal. One or more Tags contained within the radio communication system receive the radio signal. ABackscatter Modulator modulates reflection  of the radio signal using  a subcarrier signal, thereby forming a reflected modulated signal. The Interrogator receives and demodulates the reflected modulated signal. Based upon the characteristics of the demodulated signal the Interrogator can determine the identity of the Tag, and the relative velocity of the Tag with  respect to the Interrogator. The Interrogator can also determine if motion exists in the vicinity of the Interrogator, even no Tag is present, without the need for a separate motion detection system. The characteristics of the demodulated signal, can also be used to determine the characteristics of motion of the Tag, such as the vibrational frequency. Alternate embodiments allow the Interrogator to transmit a first information signal to one or more tags, specifying which Tags should respond using Backscatter Modulator means, so that the characteristics  of only particular Tags can be determined. Further alternate embodiments allow the Tag to input analog data, and perform analog to digital conversion of that data. This data may be then transmitted  to the Interrogator using Modulated Backscatter. Alternately, this data may be used as input to calculations performed in the Tag in order to analyze the frequency characteristics of the analog input. The Tag can also, based. upon the results of these calculations, identify an abnormal condition and notify the Interrogator of the existence of such a condition.

Abstract: An automatic toilet seat having two electric drives functioning independently of one another is provided. One motor is connected to the seat and the other operates a paper gripper. Both motors are controlled by appropriate sensors and by an intelligent microprocessor control device. This particular technological model has the advantage that, due to the separate arrangement with one drive motor for the pivot drive of the seat and, independent of that, one drive motor for seizing the protective cover, it is possible to operate both drives completely separately from one another and thus to link the drives by an intelligent microprocessor control.  With the intelligent microprocessor control unit, it is possible to adjust the two drives independently of one another and to adjust both of them to the site conditions (i.e., the location where the toilet seat is installed).

Abstract: Biofilm/debris is removed from interior and exterior surfaces of small bore tubing by passing an aqueous cleaning solution of water, one or more surfactants and preferably a hydrogen peroxide source, optionally including small inert solid particles, together with a gas under pressure, to create a turbulent flow within the tubing which loosens the biofilm/debris so it can be flushed from the tubing. When the exterior tubing surfaces are cleaned, the tubing is inserted in a sleeve fitted with an adaptor providing a pressure-tight seal between the tubing and the sleeve. The figure schematically shows an apparatus for cleaning interior and exterior walls of endoscopy tubing: Compressor (100) carries air in line (102) through pulsation control nozzle (104) to mixing chamber (106); air flow is controlled by pressure regulator (108).  Chamber (110) stores cleaning solution, passing it through line (112) to mixing chamber (106), and the resultant turbulent mixture passes through line (114) to adaptor (116) providing a pressure-tight fitting to a port of tubing (120), while line (115) carries cleaning solution to the exterior tubing surfaces.
