Title: Stator winding for two-pole dynamoelectric induction machines
Inventor: WATKINS WILLIAM J
IPC: H02K17/30
Filed: 1989-10-19
Abstract: Abstract Of The Present Invention A three phase two-pole induction motor includes a three phase winding wound as a two-pole winding with an effective full pitch wound winding connected in a double delta connection.  Each pole group includes a plurality of coils wound as a concentric winding or as a short pitch lap wound equivalent winding.  A 36 slot stator is illustrated and includes each phase winding wound with 2 coil units each having 2 coil groups.  Each coil group has 3 concentric coils and in the illustrated concentric winding the one phase winding has one group with coil sides in slots 1-3 and 16-18 and the second group in slot 19-21 and 34-36.  The next phase winding has similar coils in slots 4-6 and 25-27 and in slots 7-9 and 22-24.  The third phase winding has similar coils in slots 10-12 and 31-33 and in slots 13-15 and 29-30.  The coil sides of each of the two groups are connected to form a full pitch winding.  Thus, coil sides in slots 1-19, in 7-25 and in 13-31 are connected to form an effective coil spanning a full pitch of 18 slots.  The coil groups of different phase windings are connected in the double delta circuit connection including a series circuit connection for starting, and a parallel circuit connection for running.  The simplified full pitch winding for the double delta motor winding connection allows the motor to accelerate to operating speed in the start winding connection and also reduces the starting current while minimizing side pull effects and the rate of temperature rise.
Patent CA-2001734-A1 (CA)
Title: Pipe Interruptor
Inventor: OBERDORFER HANS
IPC: E03C1/10
Filed: 1989-10-30
Abstract: A  pipe  interrupter,  which  is  particularly suitable for  installation  in  a  sanitary  fitting,  comprises   in a  housing  a  chamber,  into  which  a  water inlet pipe, a water  outlet  pipe  and  a  ventilating  passage  open.   A resilient  closing  flap  comprises  an  attachment  section as well as  a  closing  section  connected  thereto  in  the manner  of  a  hinge.  Normally, as long as reduced pressure does not prevail in the  inlet  pipe,  the  closing  section covers  the  opening  aperture  of  the  ventilation passage into the chamber, so that on the  one  hand  no  atmospheric air  may  enter  and  on the other hand no water may emerge. However, if a reduced pressure occurs in  the  pipe  system, which  is  connected  to  the  inlet  pipe, then the closing section of the  closing  flap  tilts  by  a  certain  angle, until  it  closes  off  the  opening point of the inlet pipe into the chamber and on the other hand opens the ventilation passage  to  the  chamber.  In this way, water can no longer flow back into  the  inlet  pipe  and  to  the  pipe  system connected  thereto;  on  the other hand, the waterways conn-ected  after  the  chamber  are  ventilated.    Sucking-back of  contaminated  water  into  the  drinking  water  system, which is connected to  the  inlet  pipe,  is  thus  reliably prevented. The  dimensions  of  the  pipe  interrupter are small so that  it  can  be  located  in  particular  in  the base region of known sanitary fittings (Figure 1).

Patent CA-2004170-A1 (CA)
IPC: H04M9/08
Filed: 1989-11-29
Abstract: Acoustic Calibration Arrangement for a Voice Switched Speakerphone Abstract of the Disclosure An acoustic calibration circuit in a voice switched adaptive speakerphone accurately determines the type of acoustic environment in which the speakerphone is employed. The calibration circuit measures the acoustics of the room by emitting a tone burst through a loudspeaker associated with the speakerphone and measuring the returned time-domain acoustic response with a microphone also associated with the speakerphone. Obtained from this response and processed by a computer in the speakerphone are the maximum amplitude of the returned signal, and the duration of the echoes. The amplitude of the returned signal determines what level of transmit speech will be required to break in on receive speech. The greater the acoustic return, the higher that threshold must be to protect against self-switching. And the duration of the echoes determine how quickly speech energy injected into the room will dissipate, which, in turn, control how fast the speakerphone can switch from a receive to a transmit state. If the room acoustics are harsh, the speakerphone adapts by keeping its switching response comparable with that of a typical analog speakerphone. If acoustics are favorable, however, the speakerphone speeds up the switching time, lowers both the break in thresholds and the total amount of switched loss. This decrease in switched loss, while thespeakerphone is in a good acoustic environment, provides the user with noticeably more transparent performance.

Title: Method of cementing well casing to avoid gas channelling from shallow gas-bearing formations
Inventor: JOHNSON LES
IPC: C09K8/42
Filed: 1989-12-01
Abstract: PATENT     ABSTRACT         Gas channelling to the surface in the setting of surface casing can be avoided by employing a cementing processing in which a right-angle setting cement is positioned within a wellbore annulus between the wellbore and the casing above a gas-bearing zone with a low fluid loss cement slurry being placed below the right-angle setting cement. Pumping of the cement slurry is stopped for a period of time to allow the setting of the right-angle setting cement at which point pressurized pumping is resumed to displace remaining portions of the low fluid loss cement slurry into the wellbore annulus against the plug created by the set right-angle setting cement to block off gas migration and squeeze the low fluid loss cement into the gas-bearing zone.

Patent CA-2022569-A1 (CA)
Inventor: PANETTI ROMOLO
IPC: E01B35/06
Filed: 1990-08-02
Abstract: The invention relates to a programming method for the reprofiling of rails according to which the track is divided in successive sections as from a starting point and for each of these sections one proceeds for each line of rails to the measuring of the wavelength and/or of the amplitudes of the longitudinal undulations of the rolling table of the rail and to the measure of the transversal profile of the head of the rail. One compares thereafter a reference profile to the measured transversal profile and determines the transversal metal section to be removed to correct the tranversal profile of the rail, then one determines in function of the amplitudes of the longitudinal undulations of the rail the longitudinal metal section to be removed to correct the longitudinal profile of the rail. One determines the total section of metal to be removed and in function of the speed of working, of the characteristic of metal removal of each tool, and of this total metal section to be removed the necessary number of minimal tool-passes.     The invention has further for its object a machine for reprofiling the rails according to the said method.

Inventor: NORRIS KARL
IPC: G01J3/28
Filed: 1990-09-27
Abstract: In a spectrophotometric instrument, a system is provided to correct for distortion caused by rapid scanning of the spectrum. In the instrument, photodetectors detect light energy which is scanned through a spectrum at a rapid rate. An amplifier amplifies the output signal generated by the photodetectors. The output signal of the amplifier is sampled at increments and the samples are converted to digital values. A first derivative is determined from the digital values by subtracting from each value the value from the preceding increment. The first derivative values are multiplied times a constant selected to correct for the distortion and the resulting product values are added to the amplitude digital values to provide a set of corrected values representing the intensity detected by the photo-detectors.
