Patent NO-167934-C (NO)
Inventor: MERKEL JOSEF
IPC: E04G17/04
Filed: 1988-07-27
Abstract: A clip for abutting marginal flanges of forms for formworks which are used for the pouring of concrete has a cylindrical housing for two slidable arcuate clamping elements at opposite sides of a radially extending recess for the flanges. A wedge is movable between those end portions of the clamping elements which are remote from the recess to urge the elements against the exposed sides of the flanges. The wedge can be slidably coupled to the clamping elements so that it can urge the elements against or disengage the elements from the flanges in the recess.
Patent CA-2001860-C (CA)
Inventor: KORDAHI MAURICE E
IPC: G01L5/10
Filed: 1989-10-31
Granted: 1999-12-14
Abstract: In a dynamometer, a multi-roller sheave is positioned between a cable, or other elongate element, supply and the cable destination so that the cable rolls over the multi-roller sheave. The center axis of the cable changes direction from one side of the multi-roller sheave to the other side.      Tension in the cable causes the multi-roller sheave to move and consequently stress a strain gauge. A signal produced by the strain gauge is amplified into a signal that accurately indicates the tension in the cable.      Friction and wear between the cable and the dynamometer are eliminated for all practical purposes. Very accurate readings of tension are obtained.

Title: Method for increasing the speed of an alternating current motor
Inventor: PRATT RICHARD L
IPC: H02P27/06
Filed: 1990-01-26
Granted: 1995-12-12
Abstract: A motor control method is disclosed in which a drive motor is connected to an adjustable frequency power supply in which the frequency of the power supplied to the motor can be selectively varied.  While the motor is running at a constant speed as determined by the frequency of the power supplied to the motor, the value of the current being supplied to the motor by the power supply is sensed and an actual current signal representative of said actual current value is produced.  A reference current signal which is representative of a selected maximum current value and thereby a maximum load at which the motor speed may be increased is also provided.  The actual current signal is compared with the reference current signal and if the former is less than or equal to the latter, an output signal is provided.  In response to the output signal resulting from the comparison, the value of the actual frequency of the power supplied to the motor is increased to a preselected value so that the motor speed also increases.  The accel-eration rate of the motor while its speed is increasing may also be changed.

Title: Misfire detection in an internal combustion engine
Inventor: JAMES JOHN VICTOR
IPC: G01M15/11
Filed: 1991-07-26
Granted: 1999-09-14
Abstract: A method and apparatus are provided for reliably detecting misfires in an internal combustion engine during actual driving conditions by monitoring fluctuations in engine speed between consecutive firing intervals. An average acceleration over a series of firing intervals is removed from an individual acceleration measurement corresponding to a particular firing interval to give an acceleration deviation which is then normalized to an expected torque to provide a power loss measurement. The power loss measurement indicates the occurrence of a misfire with a high signal-to-noise ratio. The information derived from misfire detection can be used to prevent destruction of a catalytic converter by unburned fuel mixtures and can be used to improve vehicle driveability by correcting for or indicating needed sevice for the vehicle. The misfire detection is implemented using existing sensors and processors and is adapted to be done on-board a vehicle in real time.
