Patent CA-2006343-A1 (CA)
Title: Optical fiber connector and method
Inventor: HOKE DUANE E
IPC: G02B6/38
Filed: 1989-12-21
Abstract: Abstract of the Disclosure Optical fibers are spliced by securing them in end-to-end relationship in a tube.  Tinted epoxy is inserted into the bore.  One fiber is inserted into the bore until its endface reaches the center thereof.  As the second fiber is inserted into the other end of the bore, the length of the epoxy column in the bore is observed to diminish as epoxy is displaced into venting means associated with the bore. When the second fiber begins to buckle, movement thereof is stopped.  The central region of the tube is inspected to ascertain the disappearance of the epoxy column.  This indicates that the endfaces are in abutment.  The tube may contain an integral lens for viewing the fibers in the bore.  A stripe of appropriate color on one side of the bore provides the contrast to enhance the visibility of the tinted epoxy.

Patent CA-2010225-A1 (CA)
Inventor: MULLER WALTER
IPC: A61K9/00
Filed: 1990-02-16
Abstract: The invention relates to an arrangement for the sustained and controlled transdermal or transmucosal delivery of active substances, consisting of an impermeable backing layer, a reservoir containing active substance, a layer which is essentially free of active substance but is permeable to active substance, and a detachable protective layer. The layer free of active substance is initially brought into contact with the active substance reservoir immediately before or after the application and then lies between the reservoir and the application surface, in which respect, in the layer free of active substance, at least some of the active substance diffusing from the active substance reservoir converts into a non-bioavailable form. The conversion into a non-bioavailable form can in this case be effected by immobilising the active substance by chemical reaction or by physical interaction.

Title: Compost caddy
Inventor: HENDERSON JANET
IPC: B65F1/00
Filed: 1990-04-20
Abstract: ABSTRACT     is invention relates generally to waste disposal receptacles and,  more particularly,  to the collection and transfer of  organic kitchen waste.  Kitchen waste is generally placed in a free-standing waste  receptacle  or in a unit located in the  cupboard  under  the sink.  Since  the raising of our collective environment  conscience, more people are wisely opting to separate organic kitchen waste with the  intention of composting it.  The compost process usually  takes place  in  an  area at the rear of the  yard,  well  away  from  the kitchen.  Whether  people have gardens or not,  it is becoming  more important to separate compostable waste in the home rather than  add to our already over-burdened landfill sites.  By composting  kitchen waste we not only become better citizens of the planet, we can enjoy better-looking  lawns  and  gardens.  We propose  a  receptacle  for organic kitchen waste for storage and transfer to a compost bin. The "compost  caddy" would cut down on the number of trips to  the  bin, provide  an ideal use for recycled plastic and offer  a  convenient, hygenic,  easy  to clean and aesthetically pleasing  receptacle.  It eliminates  the need for plastic bags and allows for countertop  and under the sink models.

Title: Double tire reel spool starter
Inventor: KREMAR DJURO
IPC: B65H19/22
Filed: 1990-05-03
Abstract: DOUBLE TIRE REEL SPOOL STARTER   ABSTRACT OF THE DISCLOSURE A reel bar drive for use with a web winding system, such as the dry end of a paper making machine has a pair of driving wheels adapted to make driving contact with a peripheral end portion of a reel bar. The driving wheels are mounted on a pivotal platform located to one side of the winder. The platform is pivotable in an arcuate path having a component direction relative to the axis of the reel bar so as to move the driving wheels into driving relation with a peripheral end portion of the reel bar.  Owing to the pivotal mounting arrangement, the position of the driving wheels are adjustable to compensate for changes in the reel bar position as it commences its web reeling operation.  The reel bar drive may utilize its self weight to enhance frictional contact between the drive wheels and the reel bar.  Upon withdrawal of the supporting platform, the drive wheels are displaced completely clear of the winding system.  Thus, the reel bar drive is suitable for use with a reel bar auto-loading system and facilitates safe maintenance of component parts of the reel bar drive.

Abstract: Abstract Title:  Cordless Telephone Systems and Methods of Operation A method of transferring an identity from a portable handset to a base  station in a cordless telephone system, comprises coding the identity by a first function (F) in the handset and transmitting the coded identity from the handset to the base station.  The coded identity is further coded by a second function (G) in the base station, and the doubly coded identity is transmitted from the base station to the handset.  In the handset the doubly coded function is decoded with respect to the first function (F) to produce the identity still coded by the second function, which is transmitted from the handset to the base station where decoding with respect to the second function (G) gives the identity.

Title: Process for the preparation and manufacture of a vegetable-based substitute for anchovy paste
Inventor: REISNER THOMAS A
IPC: A23L27/10
Filed: 1990-07-04
Abstract: ABSTRACT    It is known that anchovy paste, which is used both as a con-diment in its own right and as an ingredient in secondary food products, is principally derived from the flesh of Engraulis encrasicholus, an oceanic species chiefly harvested in subtropical and tropical waters. Owing to a combination of circumstances, the supply and price of anchovy products have lately been subject to extreme fluctuation as demand for them surges and as fish stocks decline. This invention makes it possible to prepare a flavourful natural substitute for anchovy paste derived from an abundant, domestically available, vegetable source. The cap of the common wild mushroom Marasmius oreades, when partially air-dried and cured by immersion for a protracted period in edible oil, develops an aroma, flavour and colour highly resembling those of anchovies. After curing in oil, mushroom caps can be rendered into a paste by processing in a blender or emulsifier, to yield a product susceptible of serving as an inexpensive and palatable substitute for anchovy paste, whether used by itself or as an ingredient in other foodstuffs.

Abstract: CONTROL DEVICE FOR HEAT COLLECTION      TYPE VENTILATION EQUIPMENT          ABSTRACT OF THE DISCLOSURE       A control device is disclosed which suitably controls the opera-tion of first and second fans in a heat collection type ventilation equip-ment. The heat collection type ventilation equipment comprises an air supply passage for introducing the outside air into the inside, a first fan disposed in the air supply passage, an air discharge passage for dis-charging the inside air to the outside and a second fan disposed in the air discharge passage. A heat exchanger exchanges heat between the outside air passing through the air supply passage and the inside air passing through the air discharge passage. A first sensor detects the temperature of the outside air and a second sensor detects the tempera-ture of the inside air. The control device compares the sum of the tem-peratures of the outside and inside air detected by the first and second sensors with a reference temperature and operates the first fan at an operating ratio below 100% whenever the sum of the temperatures of the outside and inside air is below the reference temperature.
