Patent CA-2012055-A1 (CA)
Inventor: DETWEILER CHARLES A
IPC: E05B65/12
Filed: 1990-03-13
Abstract: An improved deck lid lock with remote release for motor vehicles.  The deck  lid  lock  employs  a  solenoid  operated axially  movable  armature  which  is  directly  coupled  to  a rotatable lever.  The lever is normally biased to a latched position.  The lever is lockingly engageable with a rotatable pawl which is normally biased to a latched position.  The pawl engages a pair of rotatable, asymmetrically oriented striker cams which are normally biased to an unlatched position.  The striker cams define a cavity for engaging a striker.  Upon energization of the solenoid, the armature is attracted to the solenoid causing it to rotate the lever so as to disengage the pawl.   The normal biasing of the striker cams overcome the biasing  of  the  pawl  to  rotate  the  striker cams  to  the unlatched position thereby opening the deck lid.   When the deck lid is closed, contact with the striker over-rotates the striker  cams  permitting  the  pawl  to  rotate  to  a  latched position thereby lockingly engaging the lever.  The deck lid lock further incluees a rotatable key cam which acts on the lever to enable release of the deck lid through conventional manual key actuations.  Improved electrical switch means are provided for signaling when the deck lid is open.

Title: Converting organic/organometallic gaseous or vaporizable compounds to inert solids
Inventor: BEATTY CHARLES L
IPC: A62D101/24
Filed: 1990-09-12
Abstract: 2040436 9104104 PCTABScor01 Closed system and process for the conversion of gaseous or a  vaporizable organic and/or organo-metallic compound to inert solid  which is resistant to solvent extraction, and is itself essentially  nontoxic or convertible through oxidation or other natural  processes to a toxic material. This process involves a low  temperature, low energy conversion, in a close system, of an organic and/or organo-metallic material by initially fragmenting such material  into its basic elements followed thereafter by randomly  recombining such elements as a solid coating or deposit upon a substrate.  In the preferred embodiments of this invention, the toxic and/or  potentially toxic material is injected as a gaseous phase into a  chamber (21) where it is subjected to an RF energy source (35),  thereby forming a plasma which is contained within the chamber by a  magnetic field produced by magnets (39) and (41). The chamber  (21), as well as, the other components of the conversion system  (25, 23) are maintained under a negative pressure through use of  vacuum pump (45). This allows for the transport of the plasma  throughout the system to a second chamber (23) where the elements of  the plasma can recombine in a random fashion. The recombination of these elements as a solid allows for ease of handling and  prevents their release into the atmosphere or ground water. Compounds  which can be subjected to this process include  chlorinatehydrocarbons i.e., methylenechloride, carbontetrachloride and  chlorofluocarbons (i.e. Freons).

Title: Colour sequential illumination system
Inventor: HOLDEN JOHN G
IPC: H01J61/42
Filed: 1991-10-11
Abstract: A colour sequential illumination system, such as, for example, a backlighting system for a liquid crystal display (LCD), comprises lamps for emitting blue, red and green light.      The red and green light is provided by lamps including fluorescent dyes having optical decay times similar to a phosphor material used to provide the blue light. In this manner, the blue, red and green emissions can be fully synchronised with electrical signals used to energise the lamps, enhancing colour range and colour quality. Furthermore, if the fluorescent dyes are carried in plastics materials, then trapping and concentration of the light generated may also be achieved, providing enhanced brightness fox the LCD for a given power input.

Title: Sectional high efficiency heat exchanger
Inventor: EVENS LANCE J
IPC: F24H3/10
Filed: 1991-11-28
Abstract: ABSTRACT OF THE DISCLOSURE   The improved sectional high efficiency heat exchanger of the present invention comprises apparatus for directing hot flue gases backwardly and into a defined lower combustion chamber. Whereupon, such hot flue gases are directed forwardly in the lower combustion chamber through the upper past thereof. The heated air stream flow is then directed into and to the rear of a lower flue pass, and finally forwardly and to the front of the heat exchanger through an upper flue pass for exiting into a flue collector box. As a result of the above structure, during the burner-"off" cycle combusting gases from the pilot burner are permitted to flow upwardly along the front wall of the lower combustion chamber and into the upper flue passes, thus permitting the heat exchanger to obtain the benefit of the heat energy of the pilot burner gas during the burner-"off" cycle.

Abstract: Abstract Driving means for a lime feeder including a vertical rotor axle (1),  at which radial arms  (2)  are arranged,  in turn supporting vertically downwards extending flat irons (3). On each arm on one side of the flat irons (3) rubber cloths (4) are arranged hanging down from the arms and along the flat irons in such a way that they by water can be pushed against the flat irons constituting a water force taking shovel, where-as they at the influence of water in the opposite direction flexibly are bent away so that the water streams past the flat irons. In this way a driving rotor and rotational movement is obtained when streaming water prevail. Via cranks in the upper end of the axle the driving power can then be taken out to in-fluence a lime feeding device with its hopper.

Abstract: METHOD OF PROVIDING THERMALLY    DEGRADABLE COMPOST BAG                       ABSTRACT        The present invention comprises a polymeric based compost bag formed with a relatively high percentage of thermal oxidative degradation catalyst, such as a transition metal salt, and, preferably, a process stabilizer.  The stabilizer permits the use of high levels of the thermal oxidative degradation catalyst without the risk of premature accelerated degradation during manufacturing and storing.  According to the present invention, the compost bags are packaged in containers which are impervious to gases and vapors thus depriving the pro-oxidant of the oxygen necessary to degrade the polymer.  The package may also provide a carrier to the loss of stabilizer during storage.  Also disclosed is a kit for the disposal of waste.
