Title: Atomic reactor core spatial power distribution determination - during commissioning esp. of pebble bed reactor without in-core instrumentation
Inventor: DAOUD HASSAN DR
IPC: G21C17/104
Filed: 1979-10-22
Abstract: In a first step the differential reactivity equivalent for a number of selected absorber rods is measured in succession, one rod at a time; all absorber rods except the one under investigation are retracted from the core during this experiment and their reactivity equivalents are compensated by nitrogen. The differential reactivity equivalent of the selected rod is measured by moving the rod through a known distance at a given position of the rod and then compensating the consequent reactivity change by the nitrogen compensation method. In a second step, this reactivity change, which is equal to the product of neutron influence function, neutron flux and a constant, is used for comparing the measured values with the calculated product of neutron influence function and neutron flux, the value of the constant being determined by a subtraction method. Rapid checking of actual with calculated values is achieved.

Title: Multipin connector in rectangular housing with fastening clip - having securing spring overlapping clip sides to prevent these slipping off pivot pins
Inventor: NOETZEL SIEGFRIED
IPC: H01R13/629
Filed: 1980-03-01
Abstract: The connector comprises an upper and lower half (1) plastic body with the fastening clip hinged on pivots (3) on the lower half. A securing spring (16b) engages with clip and body to hold the connector halves together in the closed position. In order to eliminate the tendency of the clip sides (5a) to spring off the pivot pins (3), the free limb forming one side of the slot (8a) for the pivot (3) is cranked inwards (11a). The free end (20a) of the securing spring thus fits outside the bent section (13a) and prevents the clip from springing off the pivot pin (3). The bent section (13a) also forms a bearing surface for the spring end (20a) and prevents it wearing away the side of the connector housing with repeated use.

Title: Fluorescent lamp electronic starting and protection circuit - has bistable, astable and monostable sawtooth waveform generators to operate thyristor firing transistor
Inventor: KASTNER PETER
IPC: H05B41/04
Filed: 1980-03-13
Abstract: The electronic starting and protection circuit is for fluorescent lamps having different loadings, e.g. between 20 and 65W and having preheated electrodes and includes a switching system incorporating three sawtooth waveform generator stages. These carry out three ignition testing operations in sequence to control a transistor so that a thyristor acting as the switch is fired, to ignite the lamp. The three generators are formed by a bistable stage (3), an astable stage (4) and a monostable stage (5). The bistable stage after operation by the astable stage through a transistor, releases an output signal to the transistor connected to the thyristor. After the monostable stage has been operated, it takes up a quasi-stable state and is returned to the stable by a back coupling through an output signal from two transistors, then one of these transistors passes an output signal to the thyristor control transistor.
