IPC: B60J7/22
Filed: 1990-02-28
Abstract: ABSTRACT            AIR GUIDE DEVICE FOR AN AUTOMOBILE ROOF            An  air  guide  device, which is suitable both for sliding roofs  and  for  sliding-lifting  roofs,  comprises a wind deflector  plate, pivotally journalled by hinge assemblies beneath  a  front,  fixed  automobile  roof,  the  pivotal movements  of  which  deflector  plate  are controlled by control  members,  displaceably driven by the drive system of  the  sliding  lid,  which  control  members  for  this purpose  bear from above on control surfaces formed on the wind  deflector plate.  The control members do not release the  control  surfaces  until, in the opening displacement of  the  sliding  lid,  the latter has opened sufficiently far  for  the  wind deflector plate, subject to the action of  springs  acting  in  the upward pivoting direction, to pivot  upwards beyond the automobile roof without striking the  slid  lid.    In  the reverse movement direction, the control  members  run onto the control surfaces before the sliding  lid  has  reached  its closure position and pivot the  wind deflector plate against the force of the springs into the at-rest position of the air guide device.

Title: Electrical power system with remote monitoring and control of protective relays
Inventor: SUN SHAN C
IPC: H02H7/26
Filed: 1990-09-05
Abstract: ABSTRACT OF THE DISCLOSURE         Monitoring and control of analog electromechanical protective relays and digital microprocessor based relays is integrated through a system including slave stations which record and time tag contact activity at each of the analog relays.    The  slave  stations  continuously  retain digital samples of a predetermined number of the most recent cycles of the currents and voltages at the analog relays and when a trip occurs store the retained samples as pre-fault values together with a preset number of post-fault samples.   A master  station  communicates  with  the  slave  stations monitoring the analog relays and with the digital relays through  a  two  way  communications  network.    The  master station repetitively polls the slave stations and digital relays for contact activity.  Detailed data such as the time tags and pre-fault and post-fault currents and voltages are then  requested  from  those  stations  reporting  contact activity.    Either  the  slave stations  or  master  station calculate fault location and type from the fault voltages and currents,  an periodically calculate  routine metering parameter such as watts and VARs.

Patent CA-2035507-A1 (CA)
Inventor: NOORILY PETER
IPC: H01R13/28
Filed: 1991-02-01
Abstract: An  electrical connector  for  terminating  conductors  of  a shielded multiconductor cable and for mating with a complementary electrical connector comprises an insulative housing supporting a plurality of elongate electrical contacts thereon.  The contacts include a contact engaging portion and a shunt engaging portion movably supported on the housing.  The contact engaging portion terminates in a curved free end that is axially movable within the housing.  A pair of shunt bars is disposed transversely to and in electrical engagement with shunt engaging portions of the contact thereby electrically commoning preselected pairs of electrical contacts when the connector is in a disconnected condition.  Upon electrical connection with a complementary connector, the movable portion of the contact is moved axially in the housing as a result of the free movement of the free end of the contact, thereby causing the shunt engaging portions to move transversely relative to the shunt bars and away therefrom providing a wiping action during  both  connection with  the  complementary connector  and disengagement therefrom.

Abstract: FLOTATION SEPARATION SYSTEM                    ABSTRACT OF THE DISCLOSURE    A wastewater flotation separation system is  provided, which operates effectively with a minimum of maintenance.  The apparatus includes a container  (12) for holding  wastewater, an inlet  (14) located  at a lower portion of  the container, and an aerator (24) adjacent to  the inlet  for generating air  bubbles that  cling to waste particles to bring  them to the water  surface.  A  skimming apparatus  (30)  which  skims particles  off  the  surface of  the wastewater  into a  sludge receiver (44)  includes a  beach device (42) with an inclined upper surface (40), and a belt  device (34) that moves  a series  of scrapers  (32) along  the surface  of the water and along the beach device into the  sludge discharge.  Each scraper includes a flap of resilient material which is bent as  it scrapes along the inclined beach surface.  The aerator includes an aerator  chamber (16)  substantially sealed from  the rest  of the container except at its top,  with the wastewater inlet opening to the  chamber  so bubbles  are applied  along  the upwardly-flowing stream of waste water that flows up along the box into the rest of the  container.   The aerator  includes a  rotor (80)  with hollow blades  coupled to an air tube, with  the tips (104) of the blades having  holes opening in a substantially circumferential direction to  better distribute the air  bubbles.  Recirculation pipes (110, 112, 114) extend from locations at the bottom  of the container to the bottom of the aerator chamber.

Patent CA-2048760-A1 (CA)
Inventor: YASSA FATHY F
IPC: G01R25/00
Filed: 1991-08-08
Abstract: Apparatus for measuring or compensating for phase or time delay between a reference signal and a desired signal produces an approximate error signal by differentially summing the desired and reference signals. The approximate error signal is then used, in a feedback loop, to control application of an adaptive delay to each of the reference and desired signals. The total lead or lag difference is represented by the difference between the two delays applied to the reference and desired signals, respectively. The phase or time delay measurement or compensation arrangements may be applied to linear variable differential transformers, synchronous AM detectors, zero crossing detectors and phase locked loops. Variations on this basic technique can yield substantially exact measurement or compensation. The invention is applicable to sampling arrangements including oversampling/decimation or interpolation/decimation to increase compensation accuracy to any desired degree.
