Title: Failed element detection and location system  and method for use in a nuclear reactor
Inventor: CROSGROVE ROBERT O
IPC: G21C17/04

Granted: 1982-10-19
Abstract: ABSTRACT OF THE DISCLOSURE      A failed element detection and location system for use in a nuclear reactor, for example, a liquid metal fast breeder reactor (LMFBR), which utilizes a large number of fuel pins in an active core and which circulates a continuous stream of liquid metal heat exchanging fluid such as liquid sodium past the pins is disclosed herein. This system first collects a combined sample of the fluid just as the latter passes through at least a selected group of containers, each housing a plurality of the fuel pins.  This combined sample is detected for the presence or absence of a predetermined contaminant, spec-ifically neutrons, resulting from the failure (break) in one or more of the fuel pins.  In the event that the con-taminant is detected in the combined sample, individual samples of fluid are collected, one at a time, as the fluid just  passes through the selected group of containers. These individual samples are also detected for the presence or absence of the contaminant, thereby indicating the fuel pin container or containers responsible for the presence of the contaminant.

Abstract: (Case No. 7042) ABSTRACT OF THE DISCLOSURE    A spring-applied, air-released parking brake, having a manual release mechanism with an automatic reset feature.  To release a spring-applied parking brake, in the absence of air, a torsion bolt having a cam member formed on it is manually rotated to a position aligning the cam with an elongated slot in the piston push rod of the parking brake cylinder.  This allows the piston to be extended in a direction to extend the spring, thus relieving the spring force.  Reapplication of air pressure moves the piston push rod out of the elongated slot to permit angular rotation of the bolt by its torsion spring, so as to prevent its entry in the elongated slot until the bolt is again rotated manually.

Abstract: ABSTRACT A selective calling receiver has a receiver section for receiving and demodulating radio signals.  A decoder section, which is connected to the receiver section, operates with first and second levels of power consumption for selectively receiving the demodulated signals and controlling the receiving operation.  A voltage converter section is switched off responsive to a signal from the decoder section when the circuit is operational at the first level of power consumption.  The voltage converter section is intermittently switched on and off when the circuit is operating, which requires the second level of power consumption.  A timer is activated  within a predetermined period after the power is switched to the second level.

Abstract: ABSTRACT OF THE DISCLOSURE.     To permit individual retensioning and readjustment of cable length, to compensate for stretch of cables (2) attached to the heads of bowling pins (1), each cable (2) is looped about an individual associated storage drum (6), which is secured to an individual rocker plate (9), held in a first predetermined or rest position by a spring (8).  The storage drum is prevented from rotation in a cable pay-out direction by a ratchet (22, 28), but can be rotated in cable pick-up direction by an externally controllable cable tensioning drive.  If the cable tension applied between the head of the pin and the storage drum exceeds the  force of the restoring spring (8) applied to the rocker plate, the rocker plate will pivot, thus permitting: engagement of the latch (28) of the ratchet with an electromagnetically positionable engagement element (10), thus permitting notation of the storage drum in the cable pay-out direction (D).

Abstract: A.K.Edwards - 3 Abstract of the Disclosure An automatic span line switch for high speed com-munication lines is disclosed.  The apparatus employs an alarm interface unit which is coupled to a service line terminal in order to detect a line failure mode Upon detection of such a mode, the system operates to modify the parity bit content of the transmitted digital signal in order to provide a unique code to be transmitted to a remote office connected to a near office and indica-tive of a span line failure.  The apparatus automatically proceeds to switch the failed transmission line to a back-up protection line to enable the near location to communicate with the remote location via, the back-up line.  All control signals transmitted between the loca-tions are implemented by means of unique codes which are generated by purposely modifying the parity bit content in each successive frame of the transmitted digital sig-nal.  The system further describes a priority system for preferentially switching higher priority service lines when multiple failures occur.  Various other techniques such as manual operation are disclosed to enable manual switching of protection lines during system operation.
