Patent CA-1287410-C (CA)
Title: Method of and apparatus for testing circuit boards and the like
Inventor: PROKOPP MANFRED
IPC: G01R1/073
Filed: 1989-05-30
Granted: 1991-08-06
Abstract: ABSTRACT           Circuit boards, chips and analogous components having a large number of electric contacts are contacted with an adapter wherein the rear ends of elongated flexible resilient test probes are affixed to a plate-like support and the front ends of the probes extend or can extend beyond the holes of a front plate which is maintained at a fixed distance from the support.          Intermediate portions of the probes extend with play through openings in a plate-like flexing member which is movable by a fluid-operated motor in a first direction in parallelism with the front plate to flex the probes preparatory to placing of the front plate and a component to be tested next to each other so that the contacts of the component engage or are adjacent the front ends of the probes.  The flexing member thereupon permits the probes to dissipate or to tend to dissipate at least some of the stored energy and urge their front ends against the adjacent contacts.  The flexing member can be positively moved in a second direction counter to the first direction to flex the probes in the second direction while the front ends of the probes already bear against the adjacent contacts.  This increases the pressure between the front ends and the contacts.

Title: Fire detection device for regenerative air heater
Inventor: WARRICK RICHARD J
IPC: F28F27/00
Filed: 1989-06-21
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE            A regenerative air heater is comprised of a matrix of heating surface elements contained in a compartmented housing with heat transfer  being  effected  by  alternately  exposing  the  heating surface elements to hot gas and cooler air, thereby heating the exiting air stream.  Un-burned products of combustion present in  the  gas  may  collect  on  the  heating  surface  and,  under certain operating conditions, ignite spontaneously in one or more local areas   In some instances, the local combustion can become severe enough to cause the heat transfer surface itself to burn, seriously damaging the heat exchanger.  An elongated expansion  element, made  of  a  material  having  a  high  co-efficient,  of  thermal  expansion relative  to  the  compartment structure, is used to sense the presence of a hot spot in any air  heater  compartment.   The  resulting  thermal  initiated expansion of the element activates a device  to indicate  the presence of a hot spot in the heat exchanger.

Abstract: ABSTRACT    This invention relates to an apparatus for encoding and transmitting an image.  The apparatus uses a differential pulse code modulation system including a transmission circuit for effecting a datum compression and transmission by achieving a differential pulse modulation on a digital input signal and a reception circuit corresponding to the transmission circuit.  The transmission circuit includes an estimating circuit for calculating an estimate for the digital input signal.  A movement detection circuit is used for outputting a differential signal depending on an estimated error signal.  The differential signal is then quantized by an quantizing circuit.  The quantized transmission signal is temporarily stored in an transmission data buffer circuit. Threshold values are generated by a threshold generating circuit.  A local decoding circuit decodes the quantized signal to calculate the estimation signal.  The reception circuit will then decode and regenerate the signal.

Abstract: A control unit for regulating an asynchronous motor supplied with power from a three phase network by a line-controlled power converter which is DC coupled to a self-commutated inverter has a function generator and a current regulator which controls the stator current of the motor by the controlling rectifier valves in the inverter. Control of the stator current is a function of a predeterminable value of flux fed into the function generator. In a parallel control system, an actual-value computer and a load state control regulate the stator frequency by generating a signal for controlling the self-commutating converter as a function of the actual values of the stator current, the stator voltage, and a value calculated from the function generator input variable. The computer forms signals corresponding to the amplitude of the flux vector, and to a stator current component perpendicular to the flux vector. A variable derived from the predeterminable variable is applied to the load state control as a reference value. Fall-out-proof, low oscillation, speed control is effected from low angles to nearly 90 DEG .
