Title: Seal assembly for a high speed machining system
Inventor: KOSTRZEWSKI RICHARD ANTHONY
IPC: F16J15/34
Filed: 1990-06-07
Granted: 1999-12-21
Abstract: A high speed machining system (10) including a machine tool (16) mounted on a hollow shaft (14) rotatable at high speeds and the tool (16) being operable at high feed rates. Liquid cutting coolant (22) flows to the tool (16) through the hollow shaft (14) to flush away debris from the tool (16) and for cooling the system (10). Drive means (18) including windings rotate the shaft (14), which is supported by bearings. The windings and bearings have the characteristic of long life in an environment free of liquid cutting coolant (22). The high speed machining system (l0) includes a seal assembly (30) to prevent the liquid (22) from entering the liquid-free environment of the bearings and the windings. The seal assembly (30) includes annular means for urging (52) a stationary sealing face (42) against and in annular contact with a rotating hardened sealing surface (38) to form an annular primary seal (54) for isolating the liquid (22) from the bearings and windings. First means for sealing (66) are positioned between an enlarged diameter portion of an annular face seal (40) and an inner cylindrical wall (60) of an annular retainer (58) to suppress leakage of liquid (22) therebetween. Second means for sealing (68) are positioned between an outer cylindrical wall (62) of the retainer (58) and a bore (56) defined within a housing (12) to form a tertiary seal (68) and suppress leakage of liquid (22) therebetween. In cooperation, the annular primary seal (54) and the secondary and the tertiary seals (68) cooperate to substantially eliminate leakage of liquid (22) outside the seal assembly (30) when the liquid (22) is flowing through the hollow shaft (14) to the machine tool (16) at sufficiently high pressures and volumes to remove debris from adjacent the machine tool (16), and to cool the high speed machining system (10) while the shaft (14) rotates at high speed. In alternate embodiments of the invention, different structures of seal interface are disclosed. each has the attribute of using the pressure of liquid (22) flowing in the liquid path to augment the annular means (52) for urging the annular face seal (40) against and in annular contact with the hardened sealing surface (38) to form the primary seal (66) therebetween.

Title: Rf phase shifter
Inventor: ELMER FRANK J
IPC: H01P1/18
Filed: 1990-10-23
Granted: 1994-08-02
Abstract: ABSTRACT          An electrically controlled RF phase shifter having an active medium formed from a ceramic material the permittivity of which may be varied by varying the strength of an electric field in which it is immersed.  The phase shifter includes the ceramic material having electrodes mounted thereon that are connected to an adjustable d-c voltage source.  The phase shifter may be placed in an RF transmission line that includes appropriate input and output impedance matching devices such as quarter-wave transformers.  The phase of the RF power exiting the phase shifter will depend on the effective electrical length of the material in the active medium.  Because changes in the permittivity of the material will produce corresponding changes in the electrical length of the material, changes in the phase of the RF power transmitted therein will be produced.  The quarter-wave transformers may also be made of a similar adjustable permittivity material.  Control voltages applied to the transformers are used to adjust the amount of output power.  An interdigitated electrode is used to reduce the amount of voltage needed to operate the phase shifter.  The phase shifter may be embedded as part of a microwave integrated circuit.

Title: Fiber tip atherectomy catheter
Inventor: HAMLIN ROBERT N
IPC: B08B9/04
Filed: 1990-10-26
Granted: 1995-11-07
Abstract: A catheter assembly especially designed for the performance of atherectomy procedures which includes an elongated flexible plastic tube which can be routed through the vascular system to the location of the atheroma  to  be  removed  and  a  working  catheter insertable through the guide catheter in the form of an elongated flexible plastic tube having a series of fibers integrally formed with or otherwise attached to the distal end portion of the working catheter and normally laying flat against the wall of the catheter. The proximal end of the working catheter is adapted for connection to a high speed motor whereby the working catheter can be rotated relative to the surrounding guide catheter.  As the distal end portion of the working catheter is advanced distally beyond the end of the guide catheter, centrifugal force acts upon the fibers to cause them to extend radially outward from the core of the working catheter and when advanced against an atheroma, flail the lesion, reducing it into small particles which can be aspirated out the proximal end of the catheter assembly.

Filed: 1991-12-06
Granted: 2002-02-12
Abstract: An apparatus (10) utilizing the present methods for fabricating dual textured food pieces is disclosed.      Specifically, cavities (20) are formed in and defined by the inner surfaces (26) of first and second, circular plates (22,24). The cavities (20) are moved along a circuitous path by rotation of the plates (22,24).      During the first portion of the circuitous path, the plates (22,24) abut and are pressed together by being sandwiched between a movable jaw (54) and a stationary jaw (52) and by rollers (38) rolling on the outer surfaces (28) of the plates (22,24). Two adjacent cavities (20) are simultaneously filled by a food injection manifold (42) with first and second food materials which are metered through pumps (72,74) each having two inlets (76,78) and two outlets (80,82).      After being filled, the cavities (20) are cooled by an air manifold (44). During the second portion of the circuitous path, the plates (22,24) are separated by a wedge (40) which flexes the second plate (24) away from the first plate (22). The food pieces are allowed to fall by gravity between the separated plates (22,24), with any remaining food pieces being blown out of the cavities (20) by a piccolo tube (48). In the preferred form, the bottom of the cavities (20) are initially filled by the first food material, then the first food material is coextruded with a second food material, with the first food material encircling the second food material, and the first food material is finally extruded to fill the top of the cavities (20). The resulting dual textured food piece includes a hard outer shell portion and a softer inner core portion.
