Title: Automatic coins stacker and counter
Inventor: KENLEY DELBERT M
IPC: G07D9/06
Filed: 1993-12-23
Abstract: A device for the automatic stacking and counting of coins is provided by serially positioned, inclined cartridges, each containing a plurality of coin receiving tubes. Coins sliding over the inclined superior surface of a cartridge, fall into the first-encountered coin receiving tube. Each tube collects a predetermined number of coins. Where a coin encounters a coin receiving tube that is full, it slides over the top of that tube and over any subsequentlyencountered full tubes, until an empty or partially filled tube is encountered, whereupon coins fall into that tube. Where all coin receiving tubes in a cartridge are full, coins slide over the entire length of the inclined superior surface of that cartridge onto the inclined superior surface of the adgacent downstream cartridge, and so on. Coins contained in full, coin receiving tubes are effectively counted in stacks suitable for rolling in coin wrappers.

IPC: H01M4/24
Filed: 1992-06-18
Abstract: Immobilized alkaline zinc anode for rechargeable cells which comprises zinc particles, zinc oxide, alkaline electrolyte, gelling agent. These components are mixed together and they are formed to an anode mass with predetermined shape. A conductive fiber structure is admixed to the anode mass in an amount of at least 0.15 %  weight consisting of fibers in the micron range with a length to diameter ratio between 1:100 and 1:1000 and a diameter of about 5 microns to about 20 microns. The fibers are made preferably of a non-conductive material such as polyimide and a conductive coating of copper, silver, gold or nickel is provided thereon. The fibers interconnect zinc particles and their capillary structure acts as an additional electrolyte reservoir. The increased conductivity decreases the drop in discharge capacity at higher cycle numbers.

IPC: E04H9/02
Filed: 1994-03-02
Abstract: The "FERRIS LOAD-BEARING SHIMMY PLATE" is intended as an energy absorbing connector between a rigid foundation and a superstructure and has wide application in the mounting of heavy objects and entire buildings.  Its design permits 360 degree horizontal thrust and reciprocal movement in a shear plane between a lower element attached to a foundation and an upper element attached to a superstructure in the event of an earthquake.          Its design permits upward movement by ripping the shear bolts through the metal body or breaking the shear bolts off if the ground should rise as caused by an earthquake or massive explosion.          Its design permits downward movement by deforming the opposed angles or ridges of the upper and lower elements of the unit if the ground should sink as caused by an earthquake or massive explosion.          Its design will permit it to be installed in new construction in such a way that all of the concentrated loads of the superstructure will be supported by a sufficient number of the units.          Its design will permit it to be installed in existing buildings using accepted construction practices of needling, underpinning and shoring, in such a way that all of the concentrated loads of the superstructure will be supported by a sufficient number of the units.          Its design will permit it to be used as a mount for heavy tanks or equipment, trailers and mobile homes or other industrial applications.          Manufactured in specified load-bearing capacities, it can be designated as an underwriter approved product required by insurance organizations and national building codes.          Manufactured in specified load-bearing capacities, it can be designated as an Architectural, Structural and Miscellaneous Metal as coded by the American Institute of Architects.

Patent CA-2118619-A1 (CA)
Inventor: BLAKE JULIAN G
IPC: H01L21/265
Filed: 1994-03-09
Abstract: A wafer position and clamp sensor. A circuit (114) monitors capacitance between two electrodes (22,24) within a wafer support. With no wafer on the support, the capacitance falls in one range, with the waferin place but not clamped, the capacitance falls in a second range and with the wafer held in place by an electrostatic attraction the capacitance falls in a third range. The sensed capacitance is converted to a frequency and then a D.C. voltage level that can easily be sensed and used to confirm wafer placement and then wafer clamping. After the wafer has been treated, the wafer is removed and the next subsequent wafer treated, A clamping voltage applied to clamp the wafer to its support is reversed at a controlled frequency to release the wafer. The voltage reversal disrupts the electrostatic attraction between the wafer and its support.

Title: A method for treating waste of flue gases
Inventor: NORTHROP PAUL S
IPC: C09K8/52
Filed: 1994-12-14
Abstract: This invention is directed to a method for scrubbing hazardous components from waste or flue gas in depleted or swept regions of a reservoir. In the practice of this invention, a waste gas is coinjected into a depleted or swept region along with an aqueous reactant. The swept or depleted regions serve as a reactor. The gas and an aqueous reactant in an amount sufficient to react with said gas is allowed to remain in the depleted or swept region for a time sufficient to react with said gas and remove harmful or hazardous components from the gas. Thus, harmful or hazardous components are scrubbed from the gas. When the scrubbed gas breaks through at another spaced apart site, a gas substantially devoid of harmful or hazardous components is produced to the surface.

Title: Vortex gas elimination device
Inventor: VERKARRT WESLEY H
IPC: A61M5/40
Filed: 1995-02-13
Abstract: A gas elimination device for cellular fluids has a cylindrical chamber that is divided radially into two parts by a cylindrical filter centrally located in the chamber.   The fluid inlet is directed tangentially to the outer part of the chamber to create a vortex flow.  The vortex flow is stopped by passage of the fluid through the filter, and gas bubbles that have formed rise to the top of the outer part of the chamber.   A hydrophobic membrane covers the top of the chamber and allows the gas to exit the chamber to the atmosphere.  A one way valve formed in a two part cap covering the chamber prevents flow of air into the chamber.  A float valve stops flow when the chamber fills with air.
