Patent CA-2002351-A1 (CA)
Title: Cut and trim mower
Inventor: GREGORY GLENN W
IPC: A01D34/84
Filed: 1989-11-02
Abstract: A B S T R A C T            Within the ground maintenance industry it is known that the rotation of certain materials  such as  a  steel  blade or a plastic cord, will effectively cut blades of grass and such.  This concept has been incor-porated in this device to produce an apparatus that will both cut and trim lawns and properties by simply pushing this machine like a lawnmower When trimming around obstacles such as trees, curbs, fences, tombstones etc.; all you need to do is squeeze a lever that will engage a trimhead assembly with a rotating plastic cord.   The trimhead will be located at the left front of the mower base.  This will enable to Cut and Trim Mower to go beyond the wheel base width and reach areas not accessible with a conventional  lawnmower.   This can cut in odd locations without excessive bending down.   The Cut and Trim Mower is distinct from the standard lawn mower because it functions as a weed and garden trimmer similar to a weed eater and at the same time cuts grass.    There are a  number of features novel  of this device.    First:   one motor operates both the trimmer and the grass cutter.  Secondly:  the nylon cord trim head assembly can be disengaged without shutting off the motor.  Thirdly:  this device is safe as no external blade is exposed only a  nylon cord.   Fourthly:  this device uses a nylon cord rather than a steel blade for trimming purposes.          This  is what makes this device distinct from other patents including United States Patents numbers 4,170,099; 4,242,855; 4,642,976; 4,653,254; 2,917,890; 3,304,700; 3,319,406 and 3,782,085 which the closest patent I believe is 4,170,099 but my device is novel because the blade mounting is  inside the mower itself and the drive is also more efficient and sufficient for the purposes needed. Belt drives in some of the devices are not practical for speed required. This is very durable and novel in that it will last much longer without excessive wear and  tear.   patent 4,170,099  is exposed wire with an unprotected unsafe head.

Patent CA-2004872-A1 (CA)
Title: Lenses from polymeric derivatives of acrylic and methacrylic acids
Inventor: SULC JIRI
IPC: C08J7/12
Filed: 1989-12-07
Abstract: An object of the invention is a lens made from a non-hydrophilic acrylate or methacrylate polymer or copolymer and designated for application in a water medium inside a human eye or on its surface, i.e. an intraocular or contact lens, the originally non-hydrophilic surface layer of which was additionally hydrophilized by a partial hydrolysis or sulfonation in such a way, that the gradient of swelling results where the swelling continuously changes from its maximum on the very surface to the minimum in the non-swelling core unaffected by hydrophilization. In this way, light reflexes are removed or at least substantially reduced as well as the tendency to the surface growth of cells, irritation of neighbouring living tissues, and the formation of pressure necroses.       Strong inorganic acids are most suitable for the surface hydrolysis. Their ability to swell and dissolve the employed acrylate polymer can be arbitrarily limited by dilution with water or by addition of well soluble salts. The thickness of hydrophilic layer is controlled in this way and also by the time of action.       The surface hydrophilic layer may be crosslinked by simultaneous esterification with multifunctional alcohols, in the molecule of which remains after esterification at least one additional free hydrophilic group.

Filed: 1990-02-07
Abstract: A method of applying a spin-on glass layer to a substrate is disclosed wherein the spin-on glass is applied as a plurality of contiguous thin layers that together form a composite layer. Each thin layer is cured prior to the application of the next layer at a temperature of at least about 300°C, preferably 350°C, for a time sufficient to permit catalyst connection and substantially eliminate volatile residual solvents contained therein. In this way cracking in organic SOGs can be substantially eliminated, and beneficial results can also be achieved with quasi-organic SOGs.

Patent CA-2014216-A1 (CA)
Title: Process for controlling a flotation device
Inventor: ORTNER HERBERT
IPC: B03D1/02
Filed: 1990-04-09
Abstract: ABSTRACT       In a flotation system, the generated quantity of foam is determined and, independent thereof, process parameters which directly or indirectly affect the generated foam quantity are reduced in their quantity depending on foam quantity.  This is brought about by reduction of specific substance flows and also such substance flows that circulate in a flotation system. Production waters used for dilution are partly replaced by fresh water.  This precludes an excessive amount of generated foam from causing difficulties in the operation of a flotation system.
Patent CA-2014994-A1 (CA)
IPC: G06F3/00
Filed: 1990-04-20
Abstract: ABSTRACT      An add/drop interface is connected in series with a data bus and is constructed for receiving an add/drop module.  The add/drop interface includes a data selection multiplexer which receives through data from the data bus and add/drop data from the module and selects the proper output data in response to a signal received from a controller in said interface.  The controller provides a signal to drive the data selection multiplexer to select the add/drop data only after all transient signals resulting from module connection have dissipated.  The controller also provides error checking so that the through data is selected if errors are detected.  Timing circuitry in the interface maintains the correct phase relationship between through data and add/drop data.

IPC: B29C48/154
Filed: 1990-06-20
Abstract: ABSTRACT METHOD OF MANUFACTURING AN ELASTOMERIC STRIP A method of manufacturing an elastomeric strip comprising the steps of forming a zig-zag wire or slotted metal or plastics carrier with longitudinally spaced transverse members, the spacing of which is controlled by means, such as strands connected to the members, extending longitudinally of the carrier and then extruding elastomeric material over the carrier, and subsequently degrading said means at selected longitudinal and transverse positions in the strip to change the characteristics of the strip at those selected positions.
