Patent CA-1115450-A (CA)
Inventor: PEDLOW J WATSON
IPC: E04B1/94

Granted: 1981-12-29
Abstract: ABSTRACT   A fire protective mastic is provided, whose essential component are solids including a low fusing ceramic frit, hydrated solids having chamically bonded water which is released a fire protective  water vapor when heated solids which expand or intumesce during the same heat ap-plication to form a porous, expanded or foamy insulating body, solids which have a fire break affect, such as anti-mony oxide and zinc tetraborate, and binder solids which are thermoplastic resins and serve to bind the solids into a flexible coating when applied, the binder solids being dispersed as an emulsion in water and mixed with the other solids to form a mastic.  With further addition of water it is converted to a selected viscosity for application by troweling, coating or spraying.  The mastic is applied as a coating or a precast boot upon single or grouped electric power and control cables to restrict fire propagation and to prevent self ignition of cable from fires due to over-loading or other electrical faults, or from oil, waste or trash fire sources.  The mastic is further usefully shaped into fire protective panels the latter of which, when dried, can be mounted as a protective wall insulating a section of cable passing from area to area as a fire stop. The total panel can be formed of the dried mastic, or the mastic can be coated upon ne or both sides of insulating panels such as ceramic fiber boards, to further reduce the temperature gradient through the panel upon fire exposure and thus appreciably reduce the temperature on the cold side by 50-70°F, thereby minimizing the danger of self ignition of gases or combustible materials such as cable jacketing, insulation or other flammable materials.

Granted: 1982-08-17
Abstract: ABSTRACT   A floatable passenger car for land and water cruising has a bow portion with an inclined floor, a central portion which with the bow portion forms a planing boat body and floor and includes a bulkhead at its rear end, and a rear portion, seats being located in the central and rear portions to permit passengers to be selectively seated in the rear portion for maximum water cruising speed.  The front and rear wheels are retractable into individual compartments located in the central and rear body portions, respectively, and the compartments for retaining the front wheels include sliding doors covering the openings to the compartments when the front wheels are retracted to reduce resistance during high speed cruising on the water.  A propeller shaft with a propeller on the end thereof extends rearwardly from the bulkhead and is pivotable between elevated and lowered positions.  The engine is located between the front wheels and is coupled through transmissions to the front wheels and the propeller shaft,  Reversible electric motors which may be controlled by switches operated by the driver are arranged to raise and lower the wheels and the propeller shaft.

Abstract: ROLL FUSER APPARATUS AND RELEASE AGENT METERING SYSTEM THEREFOR                   ABSTRACT OF THE INVENTION         A heat and pressure roll fusing apparatus for fixing toner images to copy substrates, the toner comprising a thermoplastic resin.  The apparatus includes an internally heated, fuser roll cooperating with a backup or pressure roll to form a nip through which the copy substrates pass with the images contacting the heated roll.  The heated fuser roll is characterized by an outer layer or surface which by way of example is fabricated from a silicone rubber, Viton or metal clad with a low surface energy material such as Teflon to which a low viscosity polymeric release fluid is applied.  Liquid release fluid is contained in a sump from which it is applied either directly or indirectly to the fuser roll.  When release agent is applied directly to the fuser roll an air seal must be used on the surface of the fuser roll to insure that the release material contacts the fuser roll.  Alternatively, when the release fluid is applied indirectly as by, for example, a metering roll, then the air seal contacts the metering roll.

Abstract: ABSTRACT      A process is described for the separation of impurities from an aqueous slurry, dispersion or suspension.  Streams of aqueous phase and an organic phase comprising a non-polar organic liquid are passed through a multi-compartment rotary contactor.  A collector reagent is present during at least part of the passage of the streams through the contactor and gives the impurities a hydrophobic surface.

The improvement comprises a three-piece valve sealing element,  That valve sealing element comprises a first hard retainer of metal or the like, a second generally cup shaped hard retainer of metal or the like and a resilient plastic component disposed between the first and second retainers and having an exposed sloped peripheral sealing sur-face which surface is adapted to engage the first valve opening defined within the valve housing.  The second retainer has a curved peripheral surface engageable with the second valve open-ing within the valve housing, the two valve openings being spaced longitudinally from each other.  The valve includes a valve stem connected to the valve sealing element for movement of said valve sealing element in the housing between the two valve open-ings.  The valve openings are generally circular as are the plas-tic sealing component and the second retainer.  Preferably the plastic sealing element comprises polyurethane and the two re-tainers comprise steel or stainless steel or the like.  The valve stem is disposed longitudinally within the housing and the valve sealing element is secured to one end thereof and extends trans-versely of the housing.  The first retainer may be a flat disc of smaller diameter than the sealing component and second retainer.          The valve sealing element provides improved gradual closing of both the first and second openings in the housing.  Moveover, the valve sealing element is readily assembled and disassembled for removal and substitution of the wearable valve sealing com-ponent.  The valve sealing element is inexpensive, durable and efficient.
