IPC: B26B19/14
Filed: 1993-09-20
Granted: 1999-03-09
Abstract: Method and apparatus for opening slits of uneven lengths in the concentric circular shaving sections of an external cutting member that is used in an electric razor using a rotary cutter that cuts the shaving sections of the external cutting member in radial directions as the external cutting member is rotated around its axis by a predetermined angle with a use of an index device.  The differences in the length of the slit are obtained by changing the cutting angle of the rotary cutter relative to the external cutting member.

Abstract: An instrument for cutting, ablating; and coagulating tissue has a rod (4) of fer romagnetic material fusion welded to the base of a conical tip (2) of copper with the rod adjacent the base of the conic being of lesser diameter than the base to provide a region to accept a potted coil (8) of wire about the rod whereby when the coil is conne cted to a constant current high frequency source the rod and tip are heated to a temperature approaching the Curie temperature of the ferromagnetic rod. As Curie temperature is approached the rod becomes essentially non-magnetic, heating decreases to produc e a temperature below Curie temperature and the cycle repeats. As a result of the excellent heat exchange interfaces produc ed by fusion welding the energy delivered to the tissue or other load which may be non-biological is closely controlled by temper ature which is self regulated. A ferromagnetic sleeve is placed about the coil to concentrate magnetic flux in the rod. An outer sleev e spaced radially from the ferromagnetic sleeve and of relatively non-heat conductive material extends from the base of the tip away from the tip to provide a handle for the instrument.

Title: Christmas-tree stand
Inventor: KRINNER KLAUS

Filed: 1992-04-15
Granted: 1999-01-19
Abstract: A Christmas-tree stand (2) essentially consists of a housing (6)  in  which  two  clamping  bars  (18,  20)  are  rotatably supported so as to allow a swivelling movement around two support pins (22, 24). The activation of the clamping straps (18,  20)  takes place via a central clamping device which essentially  consists  of  a  threaded  rod  (26)  with  two inversely threaded sections  (32,  34)  constructed thereon. When rotating the threaded rod (26), the free ends of the clamping straps  (18, 20) are moved along by the nuts  (30, 30') running along with the threaded sections (32, 34), so that a christmas-tree trunk can be fixed or fastened between the clamping straps (18, 20).

Abstract: A pick-up roll apparatus (10) is disclosed for picking up a tail (T) of a web (W) from a forming wire (12) and for transferring the tail (T) to a press felt (14) wrapping around a portion (16) of the apparatus.  The apparatus includes a perforate rotatable shell (18) which is disposed adjacent to the forming wire (12), the shell (18) having a first and a second end (20, 22). A  stationary core (24) is disposed within the shell (18), the core (24) defining a tail box (26) which is bounded by the shell (18).  The tail box (26) is disposed adjacent to one of the ends (20, 22) of the shell (18) and is selectively connected to a source of partial vacuum (52) such that when the tail (T) of the web (W) is cut on the forming wire (12), the tail (T) is drawn from the forming wire (12) onto the press felt (14) which wraps around the rotatable shell (18).  The core (24) alsodefines a downstream chamber (27) which extends between the first end and the second end (20, 22) of the shell (18).  The chamber (27) is bounded by the shell (18) and is connected to the source of vacuum (28) such that during wid-ening of the tail (T) to a full-width sheet (FNS), a flow of air through the press felt (14) and through the perforate shell (18) towards the downstream chamber (27) urges the widened tail (T) towards the press felt (14).  The tail box (26) and the downstream chamber (27) are in fluid communication with each other so that any tendency of the tail (T) to detach from the press felt (14) in the vicinity of the tail box (26) during the widening of the tail (T) is inhibited.

Abstract: This invention provides method and apparatus for an improved pattern recognition wheel slide protection system for passenger transit  type  railway  vehicles.    It  receives  as  inputs  the rotational velocities of all the axles on the vehicle, and the acceleration rates for the axles.  It also receives signals for brake  cylinder  pressure.    The  system uses  the  velocity  and acceleration data to determine whether the wheels on an axle are slipping, and determines the severity of the slip.  It calculates a timeout value based on the severity of the slip, and times a slip correction until the timeout value is reached, whereupon the slip correction is terminated. The system uses a simplified logic for providing brake control signals.  A cascade logic method is used in which  the  brake  control  signal  starts  out  indicating  full application, then, based on signals indicating change in sign of acceleration  rate,  and  acceleration  rate  in  excess  of  a predetermined value, changes the brake control signal to pulsed brake application.  Further indications based on axle velocity and acceleration cause the signal to change to a hold signal, then to a release pulse signal, and finally to a signal for release.  This cascaded logic provides signals for brake valve control which have five values, APPLY, APPLY PULSE, HOLD, RELEASE PULSE, and RELEASE. Information obtained from axle rate signals is also used to specify for the RELEASE PULSE mode the duration of release and the duration of hold.

Granted: 2005-07-05
Abstract: A system is provided for ultra-analysis of water for trace impurities. An effective trapping media (4) having internal surfaces which bear active hydroxyl groups thereon functions by binding gels that carry ultratrace analytes and contaminants on their surfaces. An X-ray source (28) may be located adjacent to the trapping medium (4) in situ. The X-rays (29) penetrate the media (4) and are reflected back into a combined emitter/receiver (30) which detects the fluorescence generated in the media (4) by the X-rays (29). The receiver (30) provides an output (31), optionally at a remote location (32) via a communication link (33), which provides data on the identity and quantity of analyses, typically heavy metals, present in the trapping media (4). By including in the transmitted data sent to the receiver (30) the output of the water meter (21, 21A) the display at the output (31) can be formatted in terms of the concentration of the measured analyzes within the sampled water stream (1).

Abstract: A method for reprocessing dialyzer cartridges (13) used with kidney dialysis machines is provided. The method involves filling the blood (19, 21) and dialysate (23, 25) compartments of the dialyzer (13) with an aqueous solution containing citric acid at a concentration of 1.0-5.0 wt. %, e.g., 1.5 wt. %, and then b; g the dialyzer (13) to an elevated temperature above 90 .degree.C and below 100 .degree.C, e.g., 95 .degree.C, for a period of at least 15 hours, e.g., 20 hours. Although citric acid is non-toxic and the temperature used is below the boiling point of water, the process has been found to produce a fully sterilized dialyzer (13). After reprocessing, the aqueous citric acid solution is preferably left in the dialyzer (13) where it acts as a bacteriostatic agent during storage. Essentially no damage to the dialyzer (13) and, in particular, to its semipermeable membrane (11) results from either the reprocessing or storage procedures.

Abstract: A master/slave discharge valve assembly for pressurized fluid containment systems includes a primary valve chamber, for connection to a fluid pressure source, formed by an eccentrically disposed first longitudinal bore and a secondary valve chamber defined by a second bore generally parallel to that of the primary chamber, communicating at one end with the primary valve chamber and at the other end with a discharge port.  A displaceable primary valve member is positioned within the primary valve chamber.  A slave valve member and an actuating piston are positioned within the secondary valve chamber.  A predetermined pressure in the discharge port displaces the actuating piston to open the slave valve member and permit a holding portion of pressurized fluid to vent to the atmosphere, thereby permitting the pressurized fluid to open the first valve member and allow pressurized fluid out the discharge port.  A master/slave valve assembly according to the invention is of lower cost to manufacture as well as simpler and sturdier in construction than known valves for carbon dioxide fire suppression systems.
