Title: Barrier-free drainage apparatus
Inventor: ZACCAI GIANFRANCO
IPC: A47K3/40
Filed: 1992-05-14
Abstract: ABSTRACT A barrier-free drainage apparatus includes a trough positioned adjacent the front edge of a platform. The trough has a bottom wall which is positioned below the front edge of the platform, and at least one outlet opening in fluid flow communication with a drain pipe. A grate is positioned inside the trough and has an upper, generally horizontal portion with a plurality of apertures therethrough. The upper portion is supported such that said upper portion is spaced apart from the trough bottom wall in a generally horizontal position and a top surface of the upper portion is substantially the same height as the front edge of the platform. Another aspect of the invention is the configuration of the outlet openings. A plurality of spaced apart, elongated insert receptacles depend from the bottom wall. The insert receptacles have side wall means and a horizontal base which define a cavity, and each base has two spaced apart outlet openings therein adjacent opposing ends of the base. Elongated inserts have a hole adjacent one end thereof and are adapted to fit into the insert receptacles. A top surface of each insert slopes downward toward the hole. When assembling the drainage apparatus, the inserts are placed in the insert receptacles so that the insert hole is in alignment with one of the receptacle base outlet openings.

Title: Separation of normally hydrophobic plastic materials by froth flotation
Inventor: HWANG JIANN-YANG
IPC: B03D1/02
Filed: 1992-07-15
Abstract: A targeted particulate, synthetic organic plastic material having normally hydrophobic surface characteristics is separated from a mixture of two or more of such plastic materials by conditioning the mixture of plastic materials in a flotation cell or the like with a heteropolar surfactant which has a hydrophile-lipophile balance (HLB) value greater than 5 and which selectively depresses the targeted plastic material by making the surfaces thereof more hydrophilic without substantially affecting the surfaces of the other plastic material(s) and introducing gas bubbles into the resulting conditioned pulp such that the gas bubbles selectively adhere to the surfaces of the other plastic materials(s) and cause them to float.  The targeted plastic material is recovered in the cell product and the other plastic material(s) is recovered in the float concentrate.

Title: High speed spindle unit and driver
Inventor: HOLTEY JAMES O
IPC: B23Q1/00
Filed: 1993-01-21
Abstract: High speed cutting with machine tools is achieved with readily available bearings of a small diameter by mounting and presetting the cutting tool directly in a spindle of a spindle unit without employing a tool holder. Preferably, the spindle unit is small like a tool holder and can be easily changed with conventional kinds of tool changing apparatus. The elimination of the tool holder allows the conventional bearings to be kept small so that they may be operated at high speeds, e.g., 20,000 to 40,000 rpm, without excessive heat that world damage the bearing.

Title: Depth stop assembly for a machine tool
Inventor: MOORE MICHAEL J
IPC: B23B47/18
Filed: 1993-02-08
Abstract: P437.US/CA    ABSTRACT            In a turret mill of the kind in which a doughnut 20 moves with the tool head along a threaded vertical rod 1, a tube 4 is slidably mounted on the rod 1 between end plates 5 and 6 which support  a turret 7.   The turret 7 can be rotated to bring a series of axially adjustable stop elements 9 into position for contact with the doughnut 20, allowing downward movement of the tool head to be stopped in various quickly selectable positions.  Such contact with a stop 9 causes the lower plate 6 to act on a head 3 secured to rod 1, which in turn operates  a cutout  17  via  a  lever  16  to  stop vertical feed of the tool head.  Upward movement of the doughnut 20 engages the upper plate 5, which acts on the rod 1 via a plunger 25 and lever 26, causing the rod to move downwards.  This again operates the cutout 17 to stop the tool head.            [Figure 1]

Title: Vaporless liquid containment system
Inventor: FURSTENBERG JOHN L
IPC: F17B1/14
Filed: 1993-02-25
Abstract: DBS\BJSVVLCS ABSTRACT OF THE DISCLOSURE         A vaporless liquid containment system for storing volatile and other liquids while preventing the formation and escape of vapors.  The vessel includes a base and a first membrane, the first membrane defines a fluid containment space for containing stored liquid.  A fluid-tight gas containment space is located above the first membrane.  The gas containment space is adapted to house a gas under pressure.  As liquid to be stored is supplied to and withdrawn from the fluid containment space, the gas housed in the gas containment space supplies fluid pressure to the first membrane so that the pressure on the first membrane is maintained above the vapor pressure of the stored liquid.  This prevents the formation of vapor caused by the evaporation of the stored liquid.

Abstract: An antiplaque mouth rinse conducive to oral hygiene.          The mouth rinse composition includes a water-alcohol vehicle having dissolved therein two antibacterial agents that coact to promote the delivery of these agents and their retention on the teeth and soft tissue in the dental region of the oral cavity of the user, thereby inhibiting the formation of plaque.  One agent, Triclosan, is water-insoluble and noncationic, a solubilizer therefor being included in the composition.  The other agent, cetyl pyridinium chloride (CPC) is soluble in water and alcohol and is cationic.

Title: Apparatus for Remote Analysis of Vehicle Emissions
Inventor: BISHOP GARY A
IPC: G01N21/35
Filed: 1991-12-20
Abstract: A gas analysis device (10) for the remote detecting, measuring and recording of NOx, CO, CO2, HC and H2O levels from the exhaust (30) of moving motor vehicles (28). It utilizes a source (11) of collimated infrared and ultraviolet radiation (15) and includes a mechanism (16) positioned on the opposite side of the roadway for receiving and measuring the infrared and ultraviolet radiation from the source (11) transmitted through the vehicle exhaust. The receiving mechanism splits the combined infrared and ultraviolet radiation into separate infrared and ultraviolet beams (42) and (40). A mechanism (44) receives the separate ultraviolet beam and generates a signal indicative of NOx. Another mechanism (27) splits the infrared beam into two to four components, and devices (35) are positioned for receiving each of the infrared components and generating two to four signals indicative of, for example, CO, CO2, HC and H2O. Another associated mechanism (17) then computes and produces signals indicative of the amount of CO, CO2, HC, NOx and H2O in the path of the infrared and ultraviolet radiation from the source, thereby making it capable of measuring emissions of vehicles.
