Patent CA-2093962-A1 (CA)
Inventor: SANFORD TIMOTHY J
IPC: G02B1/10
Filed: 1991-01-04
Abstract: A lead-free composition capable of being applied as a film and hardening to form a protective layer on the back of a mirror comprises  a fluid organic  resin  and  a  corrosion  inhibitor  selected from the group consisting of dicyandiamide, metal or acid salts of dicyandiamide, hydrogen cyanamide, and 2-cyanoacetamide.    The  organic  resin  may  be  any thermoplastic  or thermosetting  resin  suitable  for coating the reflective and other metallic layers of the mirror.   Exemplary resins include alkyd resins, acrylic  resin,  modified alkyd resins,  polyesters, urethane oils, vinyl halide polymers or copolymers, oleoresinous varnishes, nitrocellulose compositions, phenol-formaldehyde  resin  varnishes,   and  epoxy resins.    Preferably,  the  resin  is  an  alkyd  or modified alkyd resin.   The aforementioned corrosion inhibitor may be present in an amount from about 0.1 to 20 weight percent, preferably 0.5 to 10 weight percent, of the organic resin coating system.   The resin system should be essentially free of lead and lead salts.   To inhibit the corrosion of metallic film layers on mirrors,  a   mirror having a glass substrate layer and a metallic film layer thereover should be obtained,  after which the fluid organic resin coating system containing the aforementioned corrosion  inhibitor  is  applied over  the metallic film layer.   The organic resin coating system is then  hardened  to  produce  the  protective  coating layer  over  the  metallic  layer.    Other  articles having metallic surfaces may also be protected by the  resin  system  containing  the  novel  corrosion inhibitor of the present invention.

Patent CA-2096038-A1 (CA)
Title: Split-ring breakaway connector
Inventor: THUERIG PETER
IPC: F16L37/088
Filed: 1993-05-12
Abstract: A tension-activated disconnecting coupling operates by having a plug portion penetrate and pick-up an expandable locking ring. On partial with withdrawal of the plug, the locking ring is carried into a confining region where expansion of the ring is constrained and the plug is effectively locked within the coupling. Applied tension thereafter overcomes an internal spring resistance and allows the locking ring to move out further, into a space where it may expand and release the plug.

Title: High pressure soil disintegrating and excavation system using suction to remove water and particles
Inventor: KLAPTCHUK PETER
IPC: E02F3/92
Filed: 1993-08-24
Abstract: An excavation technique involves producing a high pressure jet of water having the pressure greater than 2000 psi so that the jet is communicated through a wand to a nozzle which causes the jet to rotate about a longitudinal axis of the nozzle. A vacuum duct can be moved to a position adjacent the nozzle and generates a very high airflow of at least 2000 cfm at a vacuum greater than 10 inches mercury. These parameters combine to provide an efficient and economic excavation system by which the soil impacted by the jet is broken into soil pieces and particles which are drawn away in relatively dry form for storage within an extraction tank.

Title: Computer controlled horizontal wrapper
Inventor: GINZL JEFFREY A
IPC: B65B9/067
Filed: 1993-10-28
Abstract: ABSTRACT The horizontal wrapping machine of the type wherein a succession of articles are fed into a traveling tube of web material which is sealed longitudinally and severed and sealed between the articles to produce individual hermetically sealed packages. A variable speed motor drives a conveyor which may be provided with article feeding flights and a switch, actuated once each revolution of a timing shaft, provides a pulse corresponding to each flight on the article feeding conveyor. In addition an encoder driven by the variable speed drive motor shaft provides a digital velocity signal used as a reference signal for servo motors that may be coupled, in combination or individually, to drive web feed rolls, longitudinal sealing wheels and one or more sealing and severing heads. A delivery conveyor transporting individual packages may, through a suitable drive train, be driven by the variable speed drive motor. The velocity and position of the servo motors is established and controlled through an industrial computer, at a percentage of the velocity of the variable speed drive motor. Thus, the digital velocity and position signal input to the computer by the encoder driven by the variable speed drive motor establishes a reference velocity and positions the servo motors.

Title: Method and apparatus for fractionating fatty acid ester mixtures
Inventor: WIMMER THEODOR
IPC: C10L1/02
Filed: 1994-04-05
Abstract: Abstract of the Disclosure:          Mixtures of fatty acid esters of low monovalent alcohols, for instance ethanol and methanol,  are fractionated by extractive crystallization using urea. The starting material has a given solidification point,  a first fraction is obtained with a relatively lower and a second fraction is obtained with a relatively higher solidification point than the given solidification point of the starting material. A fatty acid ester mixture is reacted with an aqueous urea solution by intensive mixing. The solid urea adduct thus obtained is mechanically separated out, leaving a mixture of two liquid phases. An oily phase (fraction F1) with the fatty acid esters having the relatively lower solidification point is separated from the aqueous urea solution. The solid urea adduct is then heated for dissociating into two liquid phases, including a light, oily phase (fraction F2), which are the fatty acid esters with the higher solidification point. The light oily phase is then separated outfrom the aqueous urea solution. Finally, the aqueous urea solutions obtained in the two separating steps are combined for use in a renewed fractionation. The oily phase (fraction F1) is used as a substitute Diesel fuel for Diesel engines above 0°C and the light, oily phase (fraction F2) at temperatures as low as -25°C.

Abstract: An auto-correlation calculation circuit (320,330) calculates an auto-correlation of an impulse response signal of a weighting function for the corresponding sub-interval of a plurality of sub-intervals of an input signal vector. A weighted cross-correlation calculation circuit (365) calculates a weighted cross-correlation of the weighted input signal vector and the weighted codevector having a length equal to a code length of the input signal vector, by using the input signal vector, a plurality of codevectors and a plurality of impulse responses.

Abstract: A hollow braid woven anchor rope having an elastic core, of tubular latex, occupies a major portion of rope length.  Ends of the elastic core are secured to the rope proper by rings, one each, located on rope end segments. A snap assembly at one end of the rope facilitates attachment to an anchor.  When not in use the elastic core collapses the rope to bunch the rope along the relaxed core.

Patent CA-2134737-A1 (CA)
Inventor: HUSTON CHARLES D
IPC: G01S19/23
Filed: 1994-10-31
Abstract: A method and system is described for determining the approximate distance from a golf ball to features on a golf course. The system includes a number of GPS receivers attached to carts (or handheld) which display the distance between the feature location and the receiver location. The GPS receiver includes a display of the golf hole being played which shows: the location of the receiver on the hole; the golf cup on the green; hazards on the hole; and the distance to the golf cup or other feature. In a preferred form, a pen input display is used and the player can designate a mark on the display and find out the distance from the receiver to the mark or the distance from the mark to the golf pin. The display preferably shows a distance grid centered about the receiver (or a mark) which allows a quick estimate of distance to the pin hazards, driving distance, target areas, to the group playing ahead, or other features on the hole. With GPS selective availability enabled, a differential error correction or calibration is used which enables distance calculation accuracy to within several meters. Without GPS selective availability, an alternative method and system is described where a calibration procedure yields distance accuracy to within several meters.. The system also includes a pro shop monitor where the location of each GPS receiver is shown on the golf course. The method and apparatus of the present invention allows the golfer to accurately select the proper club for the shot, plan a shot strategy for the hole, and to decrease playing time. The pro shop monitor enables the course to marshal play and accept player communications, such as refreshment requests, score inputs, etc.
