Abstract: A system for automatically disconnecting a conductive polymer heater if an arcing fault occurs. A sensor conductor (4) is incorporated into the heater, so that if an arcing fault occurs, the current through the sensor conductor increases and triggers a safety circuit to disconnect the heater. As illustrated in Figure 1, the sensor conductor is preferably insulated by an organic polymer (5) which pyrolyses if an arcing fault occurs and thus permits current to flow between the sensor conductor and an electrode (1) of the heater.

Abstract: A gas filter system, suitable for use in a safety installation for nuclear reactor confinement vessels, comprises a generally cylindrical enclosure having a closed bottom. In an upper part of the enclosure is an inlet for the gas to be filtered. There is an outlet for the filtered gas at the side of a lower part of the enclosure. The gas passes at a low speed through a horizontal filter bed of predetermined thickness consisting of a layer of a granular filter medium. The filter medium is supported by a supporting layer of a lightweight granular material which has an average particle size greater than that of the filter medium. This layer extends down to the closed bottom of the enclosure. The filtered gas is recovered and conveyed to the outlet by a plurality of tubular members which have walls through which the gas can pass and which are placed in the supporting layer. These tubular members discharge into an annular manifold on the outside periphery of which is the outlet for the filtered gas.

Title: Process and apparatus for filtration
IPC: A01J11/10
Filed: 1989-06-08
Granted: 1992-11-25
Abstract: In a filtration apparatus for concentrating acidulated milk, a filter unit is located between a pump and a backpressure valve. The pump used is a displacement pump, even though the liquid to be filtered would, according to its viscosity value, permit a conventionally used centrifugal pump. During an operating period, the backpressure is gradually increased so that, in spite of increasing coverage of the filter with suspended, dissolved or emulsified constituents, the permeate flow through the filter remains constant. Owing to the characteristics of the displacement pump, the delivery rate remains the same in spite of the increasing backpressure, so that the purification effect of the delivered liquid on the deposits in the filter also remains the same. An extension of the possible duration of an operating period is achieved in this way. <IMAGE>

Filed: 1989-01-05
Granted: 1994-06-22
Abstract: An arrangement is provided for checking the validity of a sensed-current signal (at 20) from a current-sensing device (24). The sensed-current signal (at 20) represents the current in a line (22). An associated control circuit (15,10) utilizes the sensed-current signal (at 20) to indicate or predict the presence of undesired overcurrent conditions. When such conditions may be present, the sensed-current signal (at 20) is checked to determine if the sensed-current signal is valid; i.e., whether the sensed-current signal (at 20) accurately represents the current in the line (22). If the sensed-current signal is invalid, no trip signal (at 25) is generated to interrupt the current (via 30). If the sensed-current signal (at 20) is valid, the control circuit (15,10) generates a trip signal (at 25) to control operation of a circuit-interrupting device (30). In a particular arrangement, the load on the current-sensing device (24) is changed (via 35,40) to determine if the sensed-current signal is valid. If the sensed-current signal (at 20) is valid, the level of the sensed-current signal remains in a valid range and the control circuit issues the trip signal (at 25). If the sensed-current signal is invalid, the level of the sensed-current signal changes. In response, the control circuit (15,10) does not issue the trip signal (at 25) and is reset to an initialized mode to monitor for a valid overcurrent condition in response to the sensed-current signal. In a specific arrangement, the current-sensing device is an iron-core transformer which saturates at high current levels.

Abstract: The invention relates to the monitoring of the spring-back of a tube (7), or other deformable elongate element, on it being bent by wrapping around a forming component (1), with clamping of the tube (in 5) at a portion (7c) located in front of the bend to be formed. 
<??>After producing the bend (7a), the portion (7c) of the tube located in front of this bend remains clamped, while its portion (7b) located to the rear of the bend (7a) is released. The extent of the spring- back is determined by a detection means (13) which carries out a measurement or a referencing on the released portion (7b) of the tube located to the rear of the bend (7a). The detection of the spring-back is made on rotation of the tube (7) and of the forming component (1) about the axis (2) of the bend (7a) by detecting the instant when the portion (7b) reaches a predetermined position. 
<??>This process enables the bending of the tube (7) to be resumed after detecting the spring-back.

Title: Charge/purge control system for air dryer
IPC: B60T17/00
Filed: 1989-06-14
Granted: 1993-09-15
Abstract: A compressed air system includes an electronic control (38) which controls enabling and disabling of the compressor (12) in response to pressure level variations in the system storage reservoir (24). The control unit responds to compressor disabling by causing the system air dryer (26) to regenerate or purge for a predetermined time period, even if the compressor is unloaded for time periods greater than the predetermined time period. If the compressor comes back on load before expiration of the predetermined time period, purging of the air dryer is immediately discontinued. Accordingly, the air dryer is never purged for long periods of time, thereby conserving the desiccant used in the air dryer, and also increasing the efficiency of the engine which operates the air compressor, since turbocharged engines normally communicate the output of the turbocharger to the air compressor, and venting a portion of the turbocharger for long periods of time can significantly decrease engine efficiency.
