Patent CA-2004398-C (CA)
Inventor: NAKATANI TETSUJI
IPC: H01P1/212
Filed: 1989-12-01
Granted: 1993-09-14
Abstract: ABSTRACT OF THE DISCLOSURE         A strip-type second-harmonic choking filter is constituted such that a main transmission line, through which a fundamental frequency wave is to be transmitted, is connected with a first stub which exhibits a first susceptance value for the fundamental frequency and exhibits a substantially infinite admittance value for a second-harmonic of the fundamental frequency, on a side of said main transmission line; and a second stub which exhibits a second susceptance value which is essentially a conjugate of the first susceptance value for the fundamental frequency and exhibits an infinity or zero admittance value for the second-harmonic frequency, at an opposite side of the transmission line from the first stub. For the fundamental frequency wave, the two stubs cancel the effects of each other so that no effect is given on the transmission of the fundamental wave, while one or both of the stubs  choke(s) the transmission of the second-harmonic wave.  The stub may be bent so that more area is easily available for circuits to be installed on the same circuit board.

Title: Method and apparatus for processing an incoming telephone call signal which may include a data message
Inventor: NUTTER WILLIAM L
IPC: H04M1/663
Filed: 1991-06-21
Granted: 1995-07-04
Abstract: A method and apparatus for processing incoming telephone calls includes structure and process steps whereby an incoming telephone calling signal having a data message associated therewith is received.  The data message is processed to determine whether it is a first type of message or a second type of message.  An alert signal is output only if the received data message is determined to be a first type of message. Preferably, the alert signal is a ring signal, and the first type of message is an ICLID message indicating the identification of the telephone call initiator or calling party.  If the incoming signal is detected as an ICLID PRIVATE signal, the phone ringer will not be activated, an off-hook signal will be returned to the caller, and a display device will indicate that the received call is an ICLID PRIVATE phone call.

IPC: F24F13/20
Filed: 1991-07-18
Granted: 1994-11-22
Abstract: The operating components of a forced air furnace are disposed within a double-walled cabinet structure having inner and outer metal walls which define therebetween an insulating air space that replaces the fibrous insulation normally adhered to the interior surface of furnace cabinetry. The illustrated cabinet structure representatively comprises a coil housing positioned atop a return housing. Each housing is formed from initially flat inner and outer sheet metal panels having rectangular configurations and various transverse projections thereon which permit the panels to be nested in a spaced apart, laterally facing relationship. Opposite end portions of the nested panels are then transversely bent in the same direction to form from the nested panels three interconnected sides of the housing, and the outer ends of the bent panel structure are secured together by elongated metal joining members extended across the resulting open fourth side of the housing. The transverse projections  on the bent panel members automatically cooperate to hold them together and to maintain the insulating air space therebetween. To complete each housing a hollow, double-walled metal access panel is removably secured to the outer ends of the bent panels and extends across the open fourth side of the housing.

Title: Air/fuel controller for internal combustion engine
Inventor: ORZEL DANIEL V
IPC: F02M25/08
Filed: 1991-10-03
Granted: 1999-03-23
Abstract: A system and method for controlling operation of an engine having a fuel vapor recovery system coupled between a fuel supply system and engine air/fuel intake. In response to a two-state exhaust gas oxygen sensor (EGO sensor), a feedback controller generates a desired fuel charge.  This feedback controller is also responsive to an adaptive learning controller which provides corrections for long term air/fuel offsets caused by such factors as fuel injector variances.  An adaptive fuel vapor learning controller measures fuel vapor concentration during purging operations of the fuel vapor recovery system.  This adaptive fuel vapor learning controller provides a fuel vapor correction factor which is subtracted from the desired fuel charge to maintain proper air/fuel ratio operation during a fuel vapor purge.  Purging operations are disabled when the measurement of fuel vapor concentration is below a preselected value.  At that time, the offset learning controller is enabled for a preselected time.  Purging operations occur until the learned measurement of fuel vapor content indicates purging is no longer necessary. Thereafter, adaptive offset learning is enabled for a preselected time.  After such preselected time, adaptive offset learning is disabled, purging operations recommenced, and adaptive vapor learning also reinitiated.
