Title: Disposable two-stage air cleaner
Inventor: KELLER DENNIS B
IPC: B01D50/00
Filed: 1995-04-19
Abstract: A disposable two-stage air cleaner includes a housing forming an air inlet, a separation chamber, a dirt collection chamber,  and an air outlet.  A filter element is located between the separation chamber and the air outlet.  The air inlet moves the air in a circular pattern in the separation chamber,  whereby dirt is thrown outwardly by centrifugal force.   An air scavenging system is employed in which air laden with dirt from the first-stage separation chamber is scooped into the dirt collection chamber and air from the dirt collection chamber  is  allowed  to  recirculate  into  the separation chamber after the air flow has been slowed so that the dirt falls from the air stream.   The air cleaner thus provides performance which is equal to or better than reusable air cleaners of the prior art.

Title: Method and system for treatment of water and wastewater
Inventor: TIMPANY PETER L
IPC: C02F3/00
Filed: 1994-09-30
Abstract: This substantially constant level biological wastewater treatment process and system enables efficient treatment of wastewater, combining the advantages and eliminating the disadvantages of both SBR and activated sludge processes. In the present case, wastewater continuously flows in one direction through a plurality of treatment cells hydraulically connected in series. The wastewater is subjected to biological treatment in at least one of the cells and settled in at least one last treatment and discharge cell, immediately prior to discharge from the system. In subsequent steps, the wastewater may continue to be fed into the system at the same location while the discharge from the last cell is temporarily closed, the mixing aeration device therein is turned on to re-suspend the settled mixed liquor suspended solids and provide additional treatment, a transfer pump therein is turned on to transfer the mixed liquor suspended solids and co-mingled partially treated wastewater back to a previous treatment cell, and at the completion of the transfer step the mixing aeration device is turned off to once again allow settling of biological solids prior to once again discharging treated wastewater on a continuing basis. Mixed liquor suspended solids flow in the same general direction as the wastewater but always receive at least partial transfer back to a prior treatment cell, settling and separation of the remaining solids from the wastewater prior to discharged of treated wastewater from the last cell. Preferred embodiments of the invention include continous discharge and essentially completely constant level operation by use of two discharge cells alternatively and treatment of soluble and particulate contaminants as well as biological removal of nitrogen and phosphorus.

Patent CA-2153514-A1 (CA)
Title: Lift installation with primary and secondary transmitter receiver means
Inventor: PLATT TERENCE CHRISTOPHER
IPC: B66B13/26
Filed: 1995-07-10
Abstract: In a lift installation in which a multi-beam curtain (primary beam) extends across a lift car door opening, auxiliary transmitters direct secondary beams towards a detection zone in front of landing doors. The multi-beam curtain is intercepted by a passenger entering the lift to prevent premature door closure. However, premature closure is also prevented when a passenger stands in front of the landing doors, thereby causing some of the secondary beam to be reflected onto auxiliary receivers. This provides a low cost solution to the problem of non-detection of an obstruction in the closing path of the landing doors, but not intercepting the primary beam system and also provides an increase in the passenger convenience of the lift, as the doors are held open for a passenger approaching the lift, but not yet interrupting the primary beams.

IPC: G01N33/50
Filed: 1994-08-11
Abstract: A method for analyzing carbohydrates involves solvolyzing the carbohydrate in anhydrous hydrogen fluoride. Solvolysis is terminated by the introduction of a carboxylic acid anhydride to the solvolyzed carbohydrate and hydrogen fluoride reaction mixture, resulting in the formation of acetic acid and acetic acid acyl fluoride. The acetic acid acyl fluoride reacts with hydroxyl groups on the solvolyzed carbohydrate to form peracylated carbohydrates. The resulting peracylated carbohydrates are dried to remove the solvent by-products, and can then be separated by gas chromatography. The gas chromatography eluents are then identified using mass spectrometry. An apparatus for automatically carrying out the solvolysis and carboxylic acid anhydride termination and acetylization steps is also provided.

Patent CA-2175914-A1 (CA)
Inventor: DANIEL CHRISTOPHER JOHN
IPC: H03G3/20
Filed: 1995-08-03
Abstract: A TDMA receiver (100) has a limiting receiver path (116) for access bursts and a linear receiver path (117) for all other traffic and signalling bursts.  Since the access bursts are not interleaved in typical TDMA digital cellular systems, such as the Global System for Mobile Communications (GSM) digital cellular system, the loss of amplitude information is not detrimental to acceptable access burst error rates in the TDMA receiver (100) implementation.   The TDMA receiver (100) determines  the burst-type (either through a priori knowledge of the burst-type or dynamic determination of the burst-type) and a selector switch (124) chooses which receiver path (116, 117) is to be demodulated.
