Abstract: Un ozoneur à plaques capable d'éliminer la déformation de cellules de décharge des plaques et d'assurer une haute efficacité en fait de génération d'ozone quand il s'agit de générer de l'ozone à concentration et à pression élevées. Un ozoneur (10) dans lequel plusieurs cellules de décharge (11) sont empilées l'une sur l'autre est placé dans un appareil à pression (20). L'appareil à pression (20) est fourni avec du gaz sous pression dont la pression est égale ou presque égale à celle des matériaux gazeux qui sont fournis audites cellules de décharge (11). Ainsi, il y a peu ou pas de différence de pression entre l'intérieur et l'extérieur des cellules de décharge (11) et ces dernières ne sont donc pas sujettes à des déformations causées par des pressions intérieures et extérieures inégales. On utilise un gaz séché comme gaz sous pression de façon à prévenir une isolation médiocre causée par l'humidification ou la condensation.
Patent CA-2092859-A1 (CA)
Title: Receiver having an adjustable matched filter
Inventor: WRIGHT ANDREW S
IPC: H04L7/02
Filed: 1993-03-29
Abstract: A radio receiver's digital matched filter (52') is intended to match a pulse-shaping filter (23) in the transmitter whose signals it receives. However, the clock signal on which the matched filter's timing is based is generated by a receiver clock (58') that is independent of the transmitter clock (56) and that is subjected to no timing adjustment to bring the two clock signals into synchronism. So as to ensure that the matched and pulse-shaping filters work together as a Nyquist filter, therefore, a timing-recovery circuit (60') senses the timing offset in the matched filter's output, and a coefficient generator (80) adjusts the matched filter's coefficients in such a manner that the filter itself imposes the delay needed for the required timing relationship between the filters.

Filed: 1992-08-28
Abstract: The present invention relates to a system and method for biologically removing nitrogen from wastewater. Both the system and method entail forming a mixed liquor and transferring the mixed liquor to a series of nitrogen removal stages. Each nitrogen removal stage includes both anoxic and aerobic treatment zones. Mixed liquor is recycled back and forth between the anoxic and aerobic treatment zone of each stage. Because of this basic flow scheme, the process gives rise to a high reactor rate and highly efficient nitrogen removal process.

Abstract: ABSTRACT           The   apparatus   comprises   a   pair   of rotatable devices each holding a plurality of metal shaping and/or cutting rollers, the rollers of one device meshing with rollers of the other device to produce  specific  designs  or  widths  of  material. This is made possible by merely selecting suitable rollers  of both  sets  and  when  production  of  a specific  metallic  section  of  desired  widths  are terminated,  other rollers are selected by rotating the rotatable devices.   When suitable rollers have been selected they are locked in operating position and when another design or widths are required, the devices are unlocked, a selection is made, and the devices are again locked to produce the new metallic section or widths of material. The present quick automated  tool  changer,  i.e.  QATC,  roll  forming apparatus  is  characterized  by  a  novel  indexing device for the two forming rolls to be used in a roll forming operation; by the use of Brushless-type motors for individually driving the shafts carrying the forming rolls in use, these motors being of the constant  torque  type;  by  quick-changing  supports carrying the rolls for allowing the rolls which are not  in  use  to  be  changed;  by  sensors  on  the cylinders providing the force on the forming rolls for giving feedback to the operator on changes in this  force;  and  by  a  pair  of  gears  selectively engageable with the gearing mechanism linking the Brushless motors to the forming rolls  in use for providing a larger range of operating speeds of the forming rolls.

Title: Blind people orientation device by creating a sound image of surrounding space
Inventor: STOJIC MILOS
IPC: G01S15/89
Filed: 1994-09-12
Abstract: The device gives direction and distance information  of  surrounding objects to a blind person, by the creation  of  an  impression  that objects emit sound signals whose frequency is decreasing with object distance,  while  use  of  the     stereophonic   headphones   makes approximate impression that  sound  signals  come  from  the  object direction.            The output from the impulse generator (1)  controls  oscillator  (2) which drives ultrasonic transmitters (OL,OD) mounted on  both  sides of stereophonic  headphones.  At  the  ultrasonic  impulse  emission moment, the oscillator (4) frequency    instantly  rises,  and  then gradually decreases.  Signals  of  reflected  ultrasonic waves  are received  by  both  ultrasonic  left  and   right   hand   receiving transducers (PL, PD) which have  the  same  spatial  orientation  as transmitting ones. These signals are separately  introduced  to  the preamplifiers  (5L,5D),  then  to  the  demodulators   (6L,6D)   and eventually  to  the  control  inputs  of  the   voltage   controlled amplifiers (7L,7D), while the output signal from the oscillator  (4) are introduced on its  inputs.    Outputs  from  voltage  controlled amplifiers are  connected  with  speakers  (ZD,ZL)  of  stereophonic headphones (S).
