Title: Method and apparatus for vaporization of liquid reactants
Inventor: CAIN MICHAEL B
IPC: B01J4/00
Filed: 1994-09-21
Abstract: Disclosed is a method and apparatus for providing reactant vapors to a utilization site.  The apparatus includes a vaporization chamber enclosed by top and bottom walls, side walls and first and second end walls.  The first end wall is elevated with respect to the second end wall.  The reactant is supplied in liquid form to a flow distributor that delivers the liquid to that portion of the bottom wall near the first end wall.  The angle with which the bottom wall is inclined with respect to horizontal is sufficient to cause the liquid to flow down the bottom wall at a rate sufficient to form a film, the thickness of which is smaller than that thickness which would support a bubble during heating of the film.  The surface is heated to a temperature greater than the boiling point of the liquid, thereby converting the liquid reactant to a vapor that is delivered to the vapor utilization site.

Filed: 1994-11-22
Abstract: A cable crosstalk measurement system provides fault diagnostic information to locates faults in addition to providing a crosstalk versus frequency function to test and troubleshoot LAN cables. In a preferred embodiment, a narrow pulse is introduced into one twisted pair of a standard LAN cable, and another twisted pair in the same cable is monitored for crosstalk signal coupling . A measurement system digitizes crosstalk signals using sequential sampling of repetitive signals to provide a waveform record that is a reconstructed equivalent time representation of a real-time crosstalk signal. A microprocessor performs a fast Fourier transform of the waveform record to provide crosstalk versus frequency information, while the waveform record is also examined for higher-than-acceptable amplitude levels to locate poor quality or faulty connectors and cables.

Abstract: A multi-branch digital optical switch (10) having three branch waveguides through which light may exit. The multi-branch digital optical switch includes a main waveguide (12), two side branch waveguides (16,18), and one center branch waveguide (14). The two side branch waveguides diverge symmetrically from the center branch waveguide at angles which are sufficiently small to allow modal evolution through the switch to be substantially adiabatic.  Electric fields are used to raise the index of refraction of one side branch waveguide above the index of the center branch waveguide and to tower the index of refraction of the other side branch below the index of the center branch waveguide. The switch has an extinction ratio of 700:1 (28 dB) between its two side branches.

Title: Disposable household floor mat
Inventor: KO YU-CHUN
IPC: A47L23/22
Filed: 1995-01-09
Abstract: A disposable household floor mat (DHFM) comprises a paper core, a mesh made of synthetic materials, a vinyl sheet and a paper under-pad, all stapled in one piece.          Size of the DHFM varies as according to household needs. The said household mat can be folded for easy storage and disposal. In this invention the paper core, comprising a minimum of one sheet of water absorbing paper and a stack of used newspaper, is used to form the main absorbing core of the DHFM. The bottom part of this mat is protected by a piece of vinyl sheet so as to prevent direct contact between the wetted paper core and the floor. The top layer of the paper core consists of a minimum of one sheet of water absorbing paper for rapid absorption and spreading of water over the entire surface of the paper core. Water is then transferred to the newspaper underneath through percolation. A mesh made of synthetic materials, covering the surface of the paper core, provides protection to the papers from abrasion. All these components are stapled together to form one single piece.          Adhesive strips are strategically fixed at the bottom part of the DHFM. This ensures the DHFM to be firmly anchored to the floor and prevents slippage. The materials of the mat renders it foldable and disposable economically. As water are held inside the paper core, the floor area can remain clean and dry .

Title: Crt faceplate panel having coded marking and method of providing same
Inventor: PEARLMAN SAMUEL
IPC: H01J9/24
Filed: 1995-07-27
Abstract: The novel method for producing a coded marking on a CRT faceplate panel having an exterior surface and an interior surface, with a viewing area surrounded by a periphery and having a luminescent screen with a plurality of different light-emitting phosphors separated by light-absorbing material, includes the steps of: depositing a suitable photoresist on the interior surface of the panel to form a layer that extends across the viewing area and onto the periphery; illuminating areas of the photoresist on both the viewing area and the periphery with actinic radiation to selectively change the solubility of the photoresist; and developing the photoresist to remove the more soluble areas, thereby exposing underlying portions of the interior surface of the panel while leaving retained areas of less soluble photoresist. The retained areas of the photoresist and the exposed portions of the interior surface of the panel are then overcoated with a light-absorbing material which is dried to form a coating. The light-absorbing coating is developed by removing the retained areas of the photoresist having the overlying light-absorbing coating thereon, while leaving the coating of light-absorbing material adhered to the exposed portions of the interior surface of the panel. The developing step forms openings in the light-absorbing coating on the viewing area and a coded marking, including a pattern of light-absorbing material and open areas, on the periphery of the panel.

IPC: B01F23/10
Filed: 1995-11-01
Abstract: A vaporizer for introducing a vapor of an anesthetic liquid into t carrier gas for introduction into a patient is disclosed. The vaporizer directly vaporizes the liquid by introducing the liquid into a vaporizing chamber having an extremely large width to height ratio, i.e. in excess of 600:1. The carrier gas flows in laminar flow through the vaporizing chamber and the liquid anesthetic is introduced at a controlled flow such that it immediately vaporizes upon introduction to the entrance of the vaporizing chamber. A control scheme utilizing a CPU controls the percentage of anesthetic vapor in the outlet gas bysensing certain parameters and then controlling the flow of liquid anesthetic bycontrolling the speed of a controllable speed pump.

IPC: A24F40/20
Filed: 1995-04-06
Abstract: A cylindrical tube (300) is provided of a mechanically strong and flexible electrical conductor such as a metal and has a plurality of separated regions. An electrically insulating layer (310) such as a ceramic is applied on the outer surface except for one exposed portion (110). Electrically resistive heaters (122) are then applied to the insulated regions and are electrically connected at one end to the underlying electrical conducting region. The electrical conductor is connected to the negative terminal of a power source. The other end of all the heaters are adapted to be connected to the positive terminal of the source. Accordingly, an electrically resistive heating circuit is formed wherein the tube serves as a common for all of the heating elements. The tubular heater can comprise an exposed end hub with a plurality of blades extending therefrom. Each blade can have an individual heater deposited thereon. Alternatively, every other blade can have a heater deposited thereon. The blades having no heaters function as barriers to minimize outward escape of generated vapors. These barrier blades also function as heat sinks for the heaters on adjacent blades.
