Granted: 1994-03-01
Abstract: ABSTRACT OF THE DISCLOSURE          A mixture of benzyl alcohol and hydroxy benzene is disclosed, for use in the bonding together of polyamide articles.  In embodiments, the mixture comprises 5 to 50% by weight of benzyl alcohol, 20 to 90% by weight of phenol and 5 to 30% by weight of polyamide.  In other embodiments, the mixture comprises 20 to 60% by weight of benzyl alcohol, 20 to 60% by weight of ortho-dihydroxy benzene and 20 to 60% by weight of a lower alcohol having one to four carbon atoms.  The mixture may be applied to a polyamide article, which may then be contacted with a second polyamide article and heated to effect bonding.  In embodiments, the mixture may be applied in a pattern e.g. to polyamide in the form of film, so that a polyamide structure having a similar pattern of bonds may be obtained.  For example, the composition may be used to bond film or sheet together so as to form fluid flow passages therebetween e.g. as in a heat exchanger.
Patent CA-1311942-C (CA)
Title: Airflow sensor and control circuit
Inventor: ZBORALSKI JAMES A
IPC: G01F1/68
Filed: 1988-04-20
Granted: 1992-12-29
Abstract: ABSTRACT           The airflow sensor uses a flow sensing bridge having a thermal element which senses airflow as a function of electrical energy applied to the bridge.  Energy is applied to the bridge to maintain the thermal element at a constant temperature and constant resistance.  A  differential  amplifier  monitors  the  balanced  and unbalanced state of the bridge and controls the application of energy to the bridge to maintain a balanced state.  A microcomputer with analog to digital converter senses the level of energy applied to the bridge and converter this energy level to a digital signal indicative of airflow.  The raw digital signal is corrected using calibration lookup tables and  thermal  compensation correction  tables  in  the microcomputer memory circuits.  The microcomputer outputs a variable frequency signal indicative of the measured mass airflow.   In the alternative to the differential amplifier, the bridge may be balanced using the microcomputer in a sample and hold voltage to current converter configuration.

Title: Arrangement for obtaining information about abandoned calls
Inventor: COMPTON MERLE F
IPC: H04M3/523
Filed: 1989-08-31
Granted: 1994-05-24
Abstract: Abstract An emergency call service system, such as an E911 system, provides service system personnel with the addresses of abandoned calls to facilitate abandoned call follow-up. When a call comes in to a "911" ANI controller, the calling number is recorded. If the call is abandoned prior to being assigned by ACD 23 to an agent position for being answered, an abandoned call ALI function is invoked to obtain information pertaining to the calling number from a database, similarly to a non-abandoned call. When obtained, the information is displayed on equipment such as a printer, terminal, or PC, to make it available to system personnel for use in following up on the call. The ANI controller serves both "911" emergency calls and emergency call-handling agents as well as other calls and other users, by switching the emergency calls to the agents and switching the other calls to the other users.
Patent CA-1317198-C (CA)

IPC: F16H59/04
Filed: 1989-09-11

Abstract: ABSTRACT OF THE DISCLOSURE A shifter assembly for a manual transmission includes a yoke mounted within a shift tower for pivotable movement about a shifting axis.  A shift lever is mounted within the yoke for pivotable movement about a selecting axis located above and perpendicular to the shifting axis.  The lower end of the shift lever extends into cooperation with conventional shift rails disposed within the transmission. By locating the shifting axis relatively close to the shift rails, a mechanical advantage is provided when moving the shift lever about the shifting axis.  Since the selecting axis is located farther away from the shift rails than the shifting axis, the lower end of the shift lever travels farther when the upper end of the shift lever is moved a predetermined distance about the selecting axis than when the upper end of the shift lever is moved about the shifting axis.  Thus, the upper end of the shift lever may be a shorter distance than would otherwise be required in order to select one of the shift rails for use, thereby providing a convenient shift pattern.  A neutral start switch is mounted in the tower adjacent to the yoke.  The neutral start switch is responsive to the pivoting movement of the yoke out of its neutral position fox generating an electrical signal.
