Patent CA-1280483-C (CA)
Title: Power line communication system
Inventor: PROPP MICHAEL B
IPC: H04B3/14
Filed: 1987-04-15
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE A power line communication system specially designed for use in local area network (LAN) configurations has receiver and transmitter sections for fast, highly reliable data communi-cation.  The receiver includes controlled adaptive second order filters for ensuring data reception in virtually any signal environment having noise and distortion characteris-tics, especially alternating current (AC) power lines.  A wideband phase shift-keyed (PSK) carrier is impressed on the the transmission medium, the carrier having power spread approximately uniformly across a useful frequency bandwidth. A transmitter section is arranged for adaptive feedback control of the transmitted signal power, so as to prevent possible damage to the transmitter when the transmission medium impedance is low.  A logic control circuit provides a correlation count of a received signal in comparison with a known reference signal in order to effectively achieve phase synchronization between the receiver and transmitter.

Title: Secure landfill and method of operating a landfill for hazardous waste
Inventor: RAKOCZYNSKI RANDOLPH W
IPC: E02D31/00

Granted: 1991-07-02
Abstract: SECURE LANDFILL AND METHOD OF OPERATING A LANDFILL FOR       HAZARDOUS WASTE                           ABSTRACT    The present invention relates to a secure landfill and to a  method  of  operating  a hazardous  waste  secure  landfill characterized  by  a substantial reduction in  the  amount  of leachate.   The amount of leachate is minimized by maintaining a  substantial  amount of the atmospheric  moisture  collected within  the  confines  of  the fill separate  from  the  waste material in the fill and removing such uncontaminated moisture from  the  fill  site and disposing of  it  outside  the  fill confines.   The present fill is divided by berms or dikes into a plurality of separate water tight zones.  The landfill has a common  low area to which liquids within the landfill flow and can  be  centrally  collected  and   monitored.    Atmospheric coisture    accumulating    in   inactive,    separated    and uncontaminated zones is collected and disposed of outside  the confines  of  the fill without mixing with  the  leachate,  or drainage, from areas of the fill in active use.  As a zone, or subdivision thereof,  is filled with waste, the filled area is closed and permanently sealed.  In such manner the landfill is progressively, incrementally closed and permanently sealed.

Title: Adhesive applicator assembly
Inventor: CAWSTON JAMES D
IPC: B31B50/62
Filed: 1987-08-14
Granted: 1991-05-07
Abstract: Abstract of the Disclosure An applicator assembly for applying hot melt adhesive to a substrate such as the end flaps of a sift-proof  carton  includes  slot  nozzles  employing elongated, wear-resistant doctor blades formed with a fluid discharge slot.  The doctor blades, preferably in the form of hardened steel plates, are releasably clamped to the body of the applicator in communication with the  outlet  of  an  internal  passageway  in  the applicator body which receives adhesive from a flow control device such as an adhesive gun.  The plates forming the doctor blades are separated by a shim to define the fluid discharge slot into which the adhe-sive flows from the internal passageway.  The lower-most ends of the doctor blades are formed in various configurations to spread the adhesive in the desired pattern or thickness on the substrate depending upon the type of adhesive employed or the requirements of a given application.

Title: Multichannel type head
Inventor: NAITO SEISHI
IPC: G11B5/29
Filed: 1988-03-11
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE         Sensors are widely used to read magnetic data and to read the magnetic and the optical patterns printed on notes and so on.  Since this invention multichannel type head has plural magnetic cores arranged in a row and a cancellation core for noise removal, the head can detect magnetic characteristics as a whole in a stationary state without depending on the relative speed of the magnetic member with the head, and therefore is least affected by noises.  Since one cancellation core is shared by plural magnetic cores, the structure as a whole becomes simple, and the manufacture cost can be remarkably reduced.  Since a magnetic head is combined with optical fibers in an integral structure according to this invention, it can read the magnetic patterns and the optical patterns on the same location simultaneously by a parallel operation.

Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE            A one piece self closing dispensing valve of molded polymer material is used in combination with a beverage container. The valve is of the kind containing a movable actuator which in response to a force applied thereto by a user, such as pressure exerted by the users finger, opens the valve to dispense liquid under force of gravity.  A leaf spring operable over the range of actuator movement and normally biasing the actuator responds to the withdrawl of the applied force to return the actuator to its normal position and thereby close the valve. An integral dripless spout is defined between the actuator and the valve body; the effective size of which is inversly dependent on the position of the actuator.

Granted: 1991-05-28
Abstract: ABSTRACT OF THE DISCLOSURE      A valve (20) has a valve housing (22) with a central passage (28) extending axially through the valve housing (22).   Apertures  (40)  in the valve housing  connect  a second passage (38) to the central passage (28) to extend through the valve housing.  A poppet valve member (24) is configured for sealing engagement of the central passage (28).  The valve member (24) is urged into sealing engage-ment with the central passage (28) by internal pressure in a container (36) on which the valve (20) is provided.  The valve member (24) and the valve housing (22) are config-ured so that the valve member  (24) will drop away from sealing the central passage (28) when the pressure in the container  (36)  is insufficient to hold the valve member (24) in sealing position against the the central passage (28) to leave the valve (20) in a permanently open state. An annular valve member (26) seals the second passage (38) in the same manner.
