Title: Container having improved drain means
Inventor: CAPPEL JEROME P
IPC: B65D47/40
Filed: 1989-12-29
Abstract: ABSTRACT OF THE DISCLOSURE      A container for liquids is disclosed, wherein the container has an improved self draining means featuring a radially inclined ramp which slopes downward from the container pouring spout in the radially outward direction.  Beneath the drain ramp is an annular channel which receives liquids gravity draining from any azimuthal location on the ramp,  and routes the liquids to a drain hole, returning the liquids to the container reservoir.  One or more projections  say  be  disposed  within  the  annular  channel  to partially  block  it.   This  arrangement  prevents  any  plastic shavings or other debris within the channel  from migrating or being washed by the draining liquids to a location visible to the user or to the drain hole where such debris may contaminate the contents of the container.

Patent CA-2025485-A1 (CA)
IPC: H04B1/40
Filed: 1990-09-17
Abstract: Both paging and cellular radiotelephone functions can be combined in a small, lightweight, single device by sharing most circuitry. The apparatus can receive paging signals simultaneously with radiotelephone signals because of dual receivers (105 and 110). When the paged party receives a page, an alert tone, a vibration, a visual indication, or a voice message is used to alert the party. Information extracted from the paging signal can be stored in memory (101) for later use. The paged party can select among messages stored in memory. If a message contains a telephone number, the paged party can call that number using the radiotelephone function at the touch of a button. The apparatus's keypad (102) can be used to program the paging function receiving frequency, identification code and type of paging system.

Abstract: A  method  for  the  biodegradation  of  organic contaminants in a mass of particulate solids.  The method comprises providing a contaminated mass of particulate solids on an impervious surface in fluid communication with an impervious recovery reservoir.   The impervious surface  has  operating  thereon  air  supply  and/or  air suction  means  to  provide   suitable  and  continuous oxygenation of the mass and/or to remove undesirable vapor emissions  from  the  mass.    The  mass  is  periodically irrigated by applying on its surface a culture medium comprising at least one bacterial strain and co-substrates thereof.  The bacterial strain has the ability to degrade the organic contaminants.  The medium is drained through the mass and washings recovered in the reservoir to be reused to irrigate the mass.   The mass is periodically mixed  and  its temperature  and  moisture  level  are controlled  to  monitor  the  biological  activity  of  the bacterial strain and to maintain the activity at levels suitable  for  the  bacterial  strain  to  degrade  the contaminants in the mass.

Title: Apparatus for emptying and rinsing non-recoverable flasks containing a toxic product
Inventor: CAUQUIL GERARD
IPC: G01N35/04
Filed: 1991-08-19
Abstract: DESCRIPTIVE ABSTRACT           In order to automatically carry out the emptying and rinsing of non-recoverable bottles or flasks (78) made from a perforatable material such as polyethylene and e.g. containing a low activity solution (88), an apparatus is proposed making it possible to pass the inverted bottles under a double-walled needle (44).  The needle (44), operated by a jack, perforates the bottom (82) of the flask (78). Compressed air is then injected into the bottle above the solution (88) through the annular passage formed between the walls of the needle (44), so as to discharge the solution through the central passage of the needle.   The flask is then rinsed by injecting pressurized water in place of the compressed air.  Finally, the rinsing water is discharged by a further compressed air injection. The emptied and rinsed flasks are then passed to a station, where they are directly discharged into a storage drum.            (Fig. 2)

Abstract: ABSTRACT     A fuel-fired water heater has a plurality of bottom end legs which hold the bottom end of the heater a few inches above the floor,  and a fuel burner positioned directly above a combustion air inlet in the bottom end of the heater body.   To assure that all combustion air delivered to the burner is taken from a height at least 18" above the floor, a bottom and portion of the water heater  is  positioned  within  a  floor  supported,  horizontally enlarged drain pan which vertically extends to at least 18" above the floor.  In one embodiment thereof, the drain pan has an open top through which combustion air enters and is drawn downwardly to the bottom air inlet of the heater, and in another embodiment the drain pan top is closed off and combustion air is ducted into the pan from a remote,  higher location.   The pan has an outlet fitting which may be connected to a pipe or hose to drain away any water leaking from the water heater, or from closely adjacent piping and/or fittings connected thereto.

Title: Control of water cleaning for reflective ash using infrared thermography
Inventor: CARTER HUDSON R
IPC: F23J3/00
Filed: 1991-12-02
Abstract: ABSTRACT           A method and apparatus of initiating and terminating the cleaning of a furnace wall to remove reflective ash which been deposited thereon, comprises a video or infrared monitor which monitors the light being reflected from the furnace wall or the ratio of the reflected to the  incident  light,  the intensity of reflected light or ratio of the reflected to the incident  light  increasing  as  additional  reflective  ash  is deposited. When the reflected light intensity reaches a selected value, cleaning is initiated and measurement of the reflected light is continued to monitor when the reflected light reaches a low substantially constant intensity.   At that point, the cleaning operation is terminated since the constant reflected light intensity indicates a substantially clean condition.

Title: Front folding no-till grain drill
Inventor: VAN BLARICON JAMES I
IPC: A01B73/06
Filed: 1991-12-11
Abstract: Abstract The front folding machine has a main fore-and-aft carrier frame provided with transport wheels that may be hydraulically actuated to raise and lower the frame simultaneously with the actuation of gauge wheels on a pair of transverse drill units connected to the rear of the carrier frame, thereby causing the trash cutters and openers which are carried by the drill units to raise out of the ground while the gauge wheels and transport wheels remain in ground engage-ment.  Before folding the drill units forwardly into transport positions extending parallel to the path of travel, the drill units are raised by hydraulically operated tool bars into elevated positions in which the gauge wheels of the units are entirely of the ground and the residue cutters are high enough to clear the transport wheels of the carrier frame as the drill units are folded into the transport position.  The tool bars which provide elevation for folding purposes are also provided with flotation pivots by which the drill units are connected to the tool bars so that the individual units can rock laterally about separate fore-and-aft pivots when the machine is unfolded and the gauge wheels encounter changes in terrain during field operations.   Flotation limit means associated with the drill units prevent excessive rocking movement during terrain changes and also assist in the control of the drill units during raising and lowering between field and transport positions.
