Title: Cap for underdrains in gravity filters
Inventor: BROWN MARVIN A
IPC: B01D24/22
Filed: 1992-03-30
Granted: 1997-04-29
Abstract: A cap for filter underdrain blocks is provided, wherein the cap has a porous body with a top surface, a bottom surface and downwardly extending flanges.  The cap is  installed on a filter block having a plurality of orifices  in  a  top  wall  of  the  filter  block  for channelling fluids to and from an overlying filter media. The bottom surface of the cap along with the flanges define a distribution chamber above the orifices, and the cap has a porosity such that a fine grain filter media may be placed directly on the top surface of the cap without media penetrating therethrough and clogging the underdrain blocks.   The distribution chamber enhances distribution of backwash  fluids throughout the  filter media,  and the cap eliminates the need for a separate gravel support layer to be installed between the fine grain filter media and the underdrain blocks.

Title: Road snow melting system using a surface heating element
Inventor: WATANABE KOJI
IPC: E01C11/26
Filed: 1992-05-22
Granted: 1998-12-29
Abstract: The present invention will automatically melt snow that has acculmulated on roads in areas having cold climates, and thus enhance the safety of vehicles and aircraft traveling on such roads and runways.

Title: Time-base correction in a video recording/playback system
Inventor: KO JUNG-WAN
IPC: H04N5/956
Filed: 1992-08-05
Granted: 1999-06-15
Abstract: A video recording/playback system includes in its recording electronics time-base correctors both for luma signal and for color-under signal, the time-base corrector for luma signal being used to facilitate comb filtering and the time-base corrector for chroma signal being used to maintain luma/chroma tracking during recording. The video recording/playback system includes in its playback electronics time-base correctors both for played-back luma signal and for played-back color-under signal, the time-base corrector for played-back luma signal being used to facilitate comb filtering and the time-base corrector for played-back chroma signal being used to maintain luma/chroma tracking during playback. With appropriate switching, the same pair of time-base correctors can be used in both the recording and the playback electronics of a video recording/playback system. A detector in the recording electronics determines when there is substantial time-base error in the video signal received for recording and conditions the comb filtering of the luma signal during recording to be carried out in just the spatial domain and not in the frame-to-frame time domain. The recording electronics includes circuitry for signaling the playback electronics, via a recorded signal, that the comb filtering of the luma signal during recording was carried out in just the spatial domain and not in the frame-to-frame time domain. The playback electronics responds to such signaling to adapt the comb filtering of the played-back luma signal to suit.

Title: Method of manufacturing a corona discharge device
Inventor: WATANABE TOSHIYA
IPC: C01B13/11
Filed: 1992-09-30
Granted: 2000-11-21
Abstract: A method of manufacturing a corona discharge device suitable for use as an ozonizer capable of producing a controlled small amount of ozone throughout a prolonged service life. A foreproduct of corona discharge device (50) is first prepared which is provided with first and second planar electrodes (54; 56) capacitively coupled, with each other by a third floating electrode (64) which is coated by a protective layer (68) of chemically-resistive electrically-insulating material. A high frequency alternating voltage having a voltage level higher than an initial minimum flashover voltage level of the foreproduct is then applied until the protective layer is aged. Aging of the protective layer is effective in lowering the initial minimum flashover voltage of the final product thus obtained as well as in reducing any fluctuation of the initial minimum flashover voltage that would otherwise occur from product to product.      Various other features are also disclosed.

Granted: 1997-11-18
Abstract: An improved method and apparatus for treating liquor containing biodegradable wastes wherein the liquor is first  delivered to a quiescent primary settling zone and then to an aeration zone.  The aerated liquor is delivered downwardly through a column of submerged fixed media having a high surface area to volume ratio so that aerobic microorganisms can grow on their surface.  The liquor is recirculated through the aeration zone and fixed media, and is withdrawn from the unit after treatment.  A portion of the aerated liquor from the top of the fixed media is  recycled back into the primary settling zone to denitrify the nitrate rich aerated liquor by deoxygenating the dissolved nitrates and to equalize the BOD load in the secondary aerobic treatment zone.

Abstract: A  handling  system  configured  for  use  with  a receptacle having a bottom, sides and a flange.   The system has a bail for supporting the receptacle, a guide for guiding the bail, and a stop structure for retaining the bail within the guide.  The bail is freely movable within the guide and is movable between two positions. In the first position, the bail extends above the flange in a carrying position.  In the second position, the bail extends below the flange in a stowed position.  The bail is preferably comprised of two substantially parallel legs connected by a base.  The two legs each include a bias structure preferably in the form of a deviation by which the base of the bail is held against an adjacent wall of the receptacle when the bail is in the stowed position. The legs of the bail pass through guide openings in the flange of the receptacle and attach to the stop structure.   In the stowed position, the stop structure substantially covers the guide openings in the flange.

Title: Trap for catching mosquitoes or all night flying insects and method therefor
Inventor: CARLE ARTHUR
IPC: A01M1/08
Filed: 1993-03-12
Granted: 1996-07-16
Abstract: The trap includes an enclosure from which it is possible to draw air therefrom thereby reducing pressure therein.   An opening is provided in the enclosure  which  enables  outside  air  to  be  drawn therein as a result of the reduced pressure,  and through which mosquitoes or night flying insects can be sucked inside the enclosure.   A container which is  associated with the enclosure  and is  separate from the device that draws air therefrom receives mosquitoes or night flying insects which have been sucked into the enclosure.   The insects should be directed toward the container without contacting the air drawing device.   By operating the device in an environment loaded with mosquitoes or night flying insects,  most  if  not  all  of  them  are  collected inside the enclosure.

Title: Method of forming cardboard tampon applicators having a dome-shaped forward tip
Inventor: KLESIUS ALLAN W
IPC: B31F1/00
Filed: 1993-05-03
Granted: 1996-09-24
Abstract: A method for forming a tampon applicator having a dome shape forward end is disclosed, in which the stability of the petal tips to maintain their closure,  is enhanced.          During the manufacture of the tampon barrel,  the petals which collectively form the dome shape tip are sprayed with a predetermined amount of moisture prior to their being presented to the heated tip forming die.   It has been observed that the addition of moisture prior to petal tip formation counteracts the tendency of the petal tips to thereafter move towards their opened condition.

Patent CA-2097118-C (CA)

Granted: 1995-04-11
Abstract: The present invention is a liquid level control system for selectively activating and deactivating a pump according to the liquid level indicated by capacitive sensors.  Activating circuitry starts the pump motor when both upper and lower sensors indicate the presence of liquid. The pump motor is latched on by the activating circuitry and continues operation until the lower capacitive sensor indicates the absence of liquid, in which case the pump is shut off.  A high frequency oscillator operates reliably over a wide range of operating conditions to maintain relatively constant charging time for the capacitive sensors.
