Patent CA-2082321-A1 (CA)
Inventor: NASEER ABSAR
IPC: H04M3/02
Filed: 1992-11-06
Abstract: A circuit for indicating the status of a telephone line at the CPE end, where the status is either on-hook ringing, or off-hook is disclosed. The telephone line is the normal two-wire telephone line. First, a transconductance amplifier converts a floating voltage difference between the two-wire telephone line into a current. The current is proportional to the voltage difference. Next, a current to voltage converter converts the current from the transconductance amplifier to a single ended ground referenced voltage. The single ended voltage is proportional to the current from the transconductance amplifier, thus the single ended voltage is proportional to the voltage difference across the two-wire telephone line. A voltage controlled switch is turned ON when the single ended voltage is greater than a predefined value indicating the on-hook status. When the single ended voltage is below the predefined value, the voltage switch is turned OFF indicating the off-hook status. Finally, the ringing status is detected when the voltage controlled switch is turned ON and OFF with a repetitive cycle proportional to the frequency of the ringing.

Abstract: An ignition timing control system controls igintion timing of spark plugs of an internal combustion engine associated with a plurality of changeover devices, changeover of an operative state of each of which has influence upon output torque of the engine.  Operating conditions of the engine are detected.  A basic ignition timing advance value is calculated based on results of detection of the operating conditions of the engine.  A changeover of the operative state of each of the changeover devices is detected.  A correction value for correcting the basic ignition timing advance value for suppressing the engine torque is calculated, in response to results of detection of the changeover of the operative state of each of the changeover devices. The largest one of a plurality of the correction values calculated is selected to a final correction value to be used for correcting the basic ignition timing advance value, when changeovers of the operative states of at least two of the changeover devices are detected substantially at the same time.

Title: Floating dock capable of varying width
Inventor: MIURA NOBUTAKA
IPC: B63C1/02
Filed: 1993-10-14
Abstract: ABSTRACT         Different from the conventional slide contact. the float member carrier frames to which the float members are integrally attached are capable of moving along the outer surface of the front and rear frame members by a rolling contact afforded by the lateral roller so that the frictional resistance that the float member carrier frame receives is drastically reduced. Accordingly, upon actuation of the means for elevating the trestle body, the float members can be easily and smoothly moved along the outer surfaces of the front and rear frame members so that the trestle body along with the small boat can be easily and safely carried to the upper trestling Position and the lower trestling position.

IPC: G01F11/04
Filed: 1994-01-26
Abstract: Système de dosage de fluide pour doser un fluide par intermittence à différents emplacements. Ce fluide provient d'un point de stockage et est ajouté par une pompe à fonctionnement intermittent dans un doseur, qui délivre un volume fixe de fluide à une sortie de manière plus ou moins indépendante de la pression. Pour renvoyer le piston alternatif présent dans le doseur, on utilise un autre fluide qui est délivré au doseur au moyen d'une autre conduite d'admission. On obtient ainsi un mouvement de retour forcé du piston. Le dosage du fluide est réalisé par le fluide de dosage lui-même alors que le mouvement de retour dans le doseur du piston est réalisé par le fluide de commande.
