Title: Pebble-bed reactor with homogeneous fuel distribution - has higher throughput at periphery than centre to improve thermal conditions
Inventor: MUELLER-FRANK ULRICH DR ING
IPC: G21C1/07
Filed: 1975-10-08
Abstract: A pebble-bed reactor has a homogeneous distribution of spherical elements (in regard to their nuclear physics characteristics) throughout the core. The flow of elements is downwards. The vertical speed of the elements in the peripheral region is greater than in the centre. Pref. where a solid side reflector surrounds the core, the vertical speed of the elements in the peripheral region is twice as high as in the centre. Constant coolant outlet temp. is obtd. across the entire core width, leading to improved thermal efficiency of the heat exchanger and longer plant life. Separate types of fuel element contg. different proportions of fuel, are not required and absolutely identical elements can be supplied across the entire width of the reactor. The fuel programme is based upon the principle of using a total burn-up rate of 60,000 Mwd per tonne, and utilising the small variation in economy through this range to obtain improved economics by more rational thermal regime.

Title: Pneumatic control valve for trailer - with fail safe interlock to isolate trailer if tractor brakes fail
Inventor: FANTOZZI ENZO
IPC: B60T15/02
Filed: 1975-11-13
Abstract: The trailer brakes are fitted with a fail-safe pneumatic brake valve which isolates the trailer brakes when the tow is uncoupled. A hand control enables an operator to release and apply the trailer brakes independently, using a trailer based reservoir. The control is arranged so that when the tow is reconnected the control is automatically reset to normal travel. Thhe fail-safe non return valve is fitted which inhibits the resetting of the control if the towing unit brakes have insufficient pressure to supply the trailer. This provides the driver a warning that the system is not operating properly, by leaving the trailer brakes. Also if the tow is broke then the trailer brakes can still be secured independently.
