Patent CA-2038730-A1 (CA)
Inventor: GAKHAR VED P
IPC: B27C5/10
Filed: 1991-03-20
Abstract: A router attachment for making dentil cuts into the surface of a workpiece is disclosed and renders a common woodworking router capable of producing fluting and edging cuts which may be straight or tapered.   The attachment comprises a top frame with a substantially flat bottom surface which rests on a workpiece and includes a base member which abuts the face of the workpiece into which the cut is to be made.  A carriage member is received on the top frame and includes  a top surface with an opening therein in order to receive a router and permit the bit of the router to extend through the opening.   Cooperating means on the carriage member and top frame is provided to slidably mount the carriage to the top frame and permit motion of the carriage relative to the base member in a direction perpendicular to front surface of the workpiece so that the carriage member can move in said perpendicular direction to permit the bit to cut into the workpiece along the perpendicular direction while the base member remains in fixed contact with the face.   Indexing means is also provided for and is mounted on the base member to position the base member and the router bit laterally along the workpiece to insure cuts therealong are made in fixed selected relationship.

Title: Inter-element mounting for stacked piezoelectric transducers
Inventor: CONGDON JOHN C
IPC: H01L41/25
Filed: 1991-05-01
Abstract: ABSTRACT          Inter-element mounting for stacked piezoelectric transducers.            In a preferred embodiment, an inter-element mounting for ceramic elements in a piezoelectric transducer stack, which mounting includes two metal plates disposed between adjacent surfaces of the ceramic elements. The metal-plates are cantilevered with respect to the surfaces of the ceramic elements, such that a substantial portion of the areas of the plates between the adjacent surfaces is unsupported and, therefore, the plates have a high degree of resilience. This structure provides controlled vibrational characteristics, structural integrity for high hydrostatic pressure, versatility in design for spurious resonance suppression or elimination, dampening, and special utility for pressure gradient hydrophone stacks.

Inventor: SWANK HARRY R
IPC: H04N5/65
Filed: 1991-05-16
Abstract: An implosion-resistant cathode-ray tube has an evacuated envelope with a faceplate panel which includes a substantially rectangularly-shaped viewing portion that extends to a peripheral sidewall. The sidewall has corners with a given radius of curvature which extends into flattened portions. An implosion protection band extends around the sidewall. A plurality of mounting lugs having each a base portion and an upstanding attachment portion cooperate with the implosion protection band. The base portion of each of the mounting lugs is disposed between the band and the sidewall. The implosion protection band is improved over prior bands by forming a plurality of concavities in the band to accommodate the base portions of the mounting lugs. The concavities prevent lateral displacement of the mounting lugs and also maximize the contact between the implosion protection band and the sidewall of the faceplate panel.

Patent CA-2044077-A1 (CA)
Inventor: MEIJER ROBERT S
IPC: A61B50/39
Filed: 1991-06-07
Abstract: An infectious waste, a solid chlorite salt, a solid acid and a preheated aqueous solvent are mixed in a treatment volume.  At least a portion of the chlorite salt and acid is dissolved in the preheated aqueous solvent incident to mixing and is reacted to form a treatment solution containing a chlorine dioxide disinfectant and a byproduct acid salt.  The infectious waste is contacted with the chlorine dioxide in the treatment solution which attacks and destroys the infectious constituents of the waste, thereby decontaminating the waste.      Upon dewatering, the decontaminated waste is suitable for landfilling.  Process control is exercised by controlling the temperature of the aqueous solvent.  A solvent temperature is selected  which  optimizes  both  the  chlorine  dioxide concentration in the treatment solution and the reactivity of the  chlorine  dioxide  with  the  infectious  constituents.          Continuous monitoring of the chlorine dioxide concentration in the treatment solution enables adjustment of the solvent preheat temperature to optimal values in accordance with the dynamics of the treatment system.

Title: Polyurethane-forming foundry binders and their use
Inventor: HENRY COLLEEN M
IPC: B22C1/22
Filed: 1990-12-17
Abstract: ABSTRACT      This invention relates to no-bake foundry binders and a no-bake process for preparing foundry shapes which utilizes polyurethane-forming foundry binders.  The binders are unique because the isocyanate component preferably contains no solvent and the weight ratio of the  phenolic resin component to isocyanate component is atypical.  It has been found that the use of these binders in a no-bake process produces foundry shapes with improved tensile strengths.

Title: Lined pipe joint and seal
Inventor: WERNER ROBERT M
IPC: F16L58/18
Filed: 1992-02-14
Abstract: A lined pipe joint with an improved collar seal and pipe lining end therefor. The pipe lining end is disposed at the end of the liner in the pipe. The lining end is adapted to shoulder against grouting material which holds the liner in place such that longitudinal contraction of the liner is prevented. The lining end also has a tapered bare therein which compensates for any inward deflection of the pipe section when threadingly engaged with a pipe fitting. The collar seal fits within the end of a pipe section which is to be connected to a pipe fitting. A sealing check valve on the collar seal provides sealing between the collar seal and the pipe section when pressure within the pipe section is greater than pressure outside the collar seal. The sealing check valve allows relief of pressure outside the collar seal into the pipe section when the pipe section is depressurized, so that damaging inward deflection of the pipe liner is prevented. A method of assembling the pipe joint is also disclosed.
