Patent CA-2101031-A1 (CA)
Title: Fault tolerant optical amplifier arrangement
Inventor: GILES CLINTON R
IPC: H04B10/272
Filed: 1993-07-21
Abstract: FAULT TOLERANT OPTICAL AMPLIFIER ARRANGEMENT         Abstract of the Disclosure For a group of optical amplifiers, pump beams from an array of lasers are mixed together to form a plurality of composite pump beams. Each composite pump beam is distributed to the pump port of a particular optical amplifier. The composite pump beam improves the reliability of each optical amplifier. Rather than having catastrophic failure of an optical amplifier occasioned by the failure of its pump laser, it is now possible to maintain fulloperation of the group of optical amplifiers even though one or more lasers fail.

Abstract: This invention relates to a method of manufacturing a homogeneous solid rubber vehicular barrier, comprising the steps of: mixing and knead melting a mixture of: 80 to 90 percent by weight particles of recycled waste rubber; 10 to 20 percent by weight virgin rubber; and an accelerator composition; forming the mixture in a mould to a selected barrier configuration thus forming a barrier; curing the mixture within the mould at a temperature of 250 to 450 C° at a pressure of 500 to 1000 psi for a period of time from 1.5 to 7.5 hours; and removing the cured barrier from the mould. A homogeneous moulded solid rubber vehicular barrier, is thereby formed of 80 to 90 percent by weight particles of recycled waste rubber in a matrix of 10 to 20 percent by weight virgin rubber. The completed barrier has a finished outer surface of cured uncontaminated rubber, and has a Shore hardness of between 65 and 70.

Title: Apparatus for monitoring elevator brakes
Inventor: LAMB MILES P
IPC: B66B5/00
Filed: 1993-08-26
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for monitoring an elevator brake includes at least one sensor and a monitoring circuit. The elevator brake has a rotating brake drum upon which a pair of brake shoes are pressed during braking. The sensor is embedded in a carrier which is mounted on the brake shoe and extends into a brake lining on the shoe. The sensor has a pair of connecting wires each formed into a generally U-shaped loop extending toward the brake drum. The sensor can be a temperature dependent resistor wherein the temperatures in the brake lining, caused by excessive braking processes, can be detected electrically. The thickness of the brake lining decreases due to wear until the brake drum connects the loops upon braking, whereby the sensor is short-circuited which condition can be detected electrically. In the case of brake lining breaks, an infinite resistance occurs between the connecting wires which can likewise be detected electrically. The sensor is connected to the monitoring circuit which employs a plurality of amplifiers connected to different reference voltage sources to convert the sensor signal into output signals representing brake conditions.

Title: Electroluminescent silicon device
Inventor: CANHAM LEIGH T
IPC: H05B33/14
Filed: 1992-03-25
Abstract: An electroluminescent silicon device (10) includes a silicon structure (12) which comprises a bulk silicon layer (14) and a porous silicon layer (16). The porous layer (16) has merged pores (20) which define silicon quantum wires (18). The quantum wires (18) have a surface passivation layer (22). The porous layer (16) exhibits photoluminescence under ultra-violet irradiation. The porous layer (16) is pervaded by a conductive material such as an electrolyte (24) or a metal (48). The conductive material (24) assures that an electrically continuous current path extends through the porous layer (16); it does not degrade the quantum wire surface passivation (22) sufficiently to render the quantum wires (18) non-luminescent, and it injects minority carriers into the quantum wires. An electrode (26) contacts the conductive material (24) and the bulk silicon layer has an Ohmic contact (28). When biased the electrode (26) is the anode and the silicon structure (12) is the cathode. Electroluminescence is then observed in the visible region of the spectrum.

Title: Air bag toy
Inventor: BEARS JAMES ALFRED
IPC: A63F9/00
Filed: 1992-09-30
Abstract: A flexible, low friction, rideable sliding toy is disclosed that slides over relatively smooth, firm surfaces (140) with very low friction. The toy is comprised of a bag (100) of flexible, air impermeable material having one or more relatively large holes (112) cut out of the bottom of the bag where the bag contacts the floor when in use. The bag is inflated by allowing it to drop onto the floor, trapping air inside it as it lands. The outer edges of the hole form a relatively air-tight seal allowing the bag to retain its inflated state when laid upon by a user, thus permitting a user to propel himself over flat surfaces in a low friction manner.

Title: Envirowaste conversion system
Inventor: BURKINSHAW ORVILLE V
IPC: F23G5/027
Filed: 1994-04-28
Abstract: This invention was developed by combining a series of technologies to work in concert to convert wastes to useful commodities.  A vast improvement over just moving waste to different locations.     Combustible materials such as municipal garbage, tires, plastic, paper, etc. are converted to gases in a high temperature, oxygen starved oven, that has proven capable of burning without emitting smoke or unacceptable emissions. The gases are burned in high temperature after-burners creating energy that is used to generate electricity and heat. In other words co-generation using tires and garbage for fuel.     The Thermophilic Digester draws heat from the burner to create an ideal environment to enhance the production of enzymes. Electricity is supplied from the co-generation unit to operate the pumps, choppers and compressor. Air is injected in perforated pipes that are situated in the bottom of round horizontal tanks to provide oxygen for the bacterial function and convectively circulates the sludge without the need for mechanical paddles. This system reduces maintenance and operating costs.     The odours and gases generated by the digestors in the treatment process are drawn off and channelled into the oven and afterburners.  The undigestible solids that remain are used as fertilizer. In the event they contain heavy metals as occurs in some areas these are recovered by dissolving said metals with sulphur dioxide in a closed circuit system and separating same by precipitation and filtration.
