Title: Cyclone separator.
Inventor: PRENDERGAST GAVAN JAMES JOSEPH
IPC: B04C5/04
Filed: 1985-01-24
Abstract: A cyclone separator (10) having an inlet with inner and outer profiles (84, 82), viewed in section transverse to the separator axis. This location of any particular point on the outer profile (82) is defined by a vector contained in a plane normal to the separator axis, and having its origin at a location (C) where the outer profile meets the adjacent inner circumference (86) of the separator. As the magnitude of the vector (T) increases, an angle ( theta ) between the vector (T) and a tangent (92) to the circumference (C) which passes through location (C) never decreases and never becomes less than zero. The location of any particular point on the inner profile (84) is defined by a vector (U) having its point of origin at a location (E) where the inner profile or at least its projection meets the separator circumference (86). As the magnitude of vector (U) increases, an angle ( zeta ) between vector (U) and a tangent (93) to the circumference (86) which passes through location (E) never decreases and never becomes less than zero, at least for substantial magnitudes of vector (U). Further modification of the separator is the end wall of the separating chamber portion (14) adjacent overflow outlet (25) is formed of curved configuration. A still further modification is where overflow outlet (25) is formed from a duct (27) which extends through the end wall into the separating chamber (14) a short distance.

Title: Making and testing an integrated circuit using high density probe points
IPC: G01R31/3185
Filed: 1991-02-14
Abstract: Each transistor or logic unit on an integrated wafer (1) is tested prior to interconnect metallization. By means of CAD software, the transistor or logic units placement net list is revised to substitute redundant defect-free logic units for defective ones. Then the interconnect metallization is laid down and patterned under control of a CAD computer syste. Each die in the wafer thus has its own interconnect scheme, although each die is functionally equivalent, and yields are much higher than wich conventional testing at the completed circuit level. The individual transistor or logic unit testing is accomplished by specially fabricated flexible tester surface (10) made in one embodiment of several layers of flexible silicon dioxide, each layer containing vias and conductive traces leading to thousands of microscopic metal probe points (15-1, 15-2) on one side of the test surface (10). The probe points (330) electrically contact the contacts (2-1, 2-2) on the wafer (1) under test by fluid pressure. <IMAGE>

Title: Mass spectrometry method using supplemental ac voltage signals.
Inventor: KELLEY PAUL E
IPC: G01N27/62
Filed: 1992-08-28
Abstract: A mass spectrometry method in which a supplemental AC voltage signal having at least one high power frequency component, and at least one low power frequency component, is applied to an ion trap. Each high power component has an amplitude sufficiently large to eject one or more selected ions from the trap, by resonantly exciting the ions. Each low power component has an amplitude sufficient to induce dissociation (or reaction) of one or more selected ions, but insufficient to resonate the ions for detection. The frequency (or band of frequencies) of each high and low power frequency component is selected to match a resonance frequency of ions having a desired mass-to-charge ratio. Each low power component is applied for the purpose of inducing dissociation or reaction of specific trapped ions, which may be parent, daughter, reagent, or product ions, and each high power component is applied to eject undesired products of each such dissociation or reaction process from the trap. In accordance with the invention, a supplemental voltage signal having appropriately selected high and low power frequency components is applied to a trap during an (MS)n or CI, or combined CI/(MS)n, mass spectrometry operation.

Title: A spatially distributed sma actuator film
Inventor: MAYNARD RONALD S
IPC: A61M25/01
Filed: 1994-02-24
Abstract: A flexible VLSI film containing shape memory alloy (SMA) actuator elements and associated control and driver circuitry is wrapped around any bendable element such as a flexible, hollow tube, catheter tube or the like. The SMA actuator elements are thus spatially distributed around the circumference of the bendable element. The SMA actuator elements are selectively resistively heated with an electric current through associated decode and driver circuitry, thereby causing a portion of the film to contract. The radical distribution of the SMA actuator elements across the surface of the VLSI actuator film is such that when properly activated, a device sheathed with the VLSI film is capable of executing highly dexterous maneuvers in three-dimensional space, which was not heretofore possible. The actuator elements are self-guided in that control circuitry, decode circuitry and associated microprocessors, including position mapping means are fabricated in VLSI integrally with the SMA actuator elements. Alternatively, a microprocessor controller may be located at a remote location while communicating with associated driver circuitry on the actuator film.
