Title: Flip=flop counter circuit using one-in-ten code - has group of flip=flops for each decade triggered twice in opposing sequence
Inventor: MERKLE PAUL
IPC: H03K23/54
Filed: 1980-05-10
Abstract: The counter circuit uses 5 flip-flops for each decade. Two setting pulse lines are associated with each decade incorporating transistors between the flip-flops. The transistors of one setting pulse line are controlled by one of the flip-flop outputs, while those of the other setting pulse line are controlled by the opposite flip-flop outputs. Each flip-flop uses a pair of transistors, a pair of diodes, two resistors and two capacitors. The flip-flops are triggered in the reverse series sequence when counting from 6 to 10 then when counting from 1 to 5, so that the decade group is automatically returned to zero. The circuit requires half the normal number of flip-flops and does not require complicated additional circuits.

Title: Fluidised bed furnace for coating nuclear fuel particles - has load bearing inner insulation and lighter outer insulation with gas cooling
Inventor: BARNERT EIKE DIPL ING DR
IPC: C23C16/442
Filed: 1980-06-07
Abstract: A fluidised bed furnace for coating nuclear fuel particles has the fluidised bed chamber surrounded by cooled thermal insulation. This insulation is subdivided into two or more zones the inner zone or zones are load-bearing, while the outer zone has a low coefficient of thermal conductivity. The insulation is gas-cooled, esp. by a cooling gas duct arranged in turns. More specifically, two sets of cooling gas ducts are used, through which the gas flows in opposite directions. The cooling ducts are spirally wound, while the remainder are helically wound around the outer, light insulation. Used for the production of coated particle fuel of either fissile or fertile type. The use of a load-bearing material for the inner insulation enables the fluidised bed chamber to be supported, while still providing adequate thermal insulation. The use of a cooling gas instead of water eliminates the difficulties incurred by the action of water as a moderater; by using a gas the effective volume provided by the critical limit of the chamber is increased by 20 times. Particularly if inert gases, such as nitrogen, carbon dioxide or the like are used, there is no risk of combustion.

Title: Emergency AC power unit - has voltage regulator which stabilises voltage using pulse-width modulation and battery voltage regulator (SE 5.4.82)
Inventor: RATHMANN SOEREN HENRIK NIELSEN
IPC: H02J9/06
Filed: 1980-09-02
Abstract: In the emergency power unit for an alternating current load (1), there are connections for an AC generator (10) and a battery (5), which can be charged by rectified current from the generator and a controllable bidirectional converter (6) between the battery and the load. An alternating voltage regulator (13) stabilises the voltage on the AC side (3) of the converter (6) by means of pulse-width modulation, and a battery of voltage regulator (12) operating by phase-shifting on the AC side of the converter (6). The generator (10) can be connected in parallel to the AC side of the converter and a current-limiting device (8) is located between the AC side of the converter (6) and the generator. In order to provide metallic isolation between the converter and the generator, and between the load (1) and the generator, the current-limiting device (8) may be a leakage reactance transformer which has three windings. The leakage-reactance transformer effects not only metallic isolation, but at the same time effects the required current limitation as a consequence of its leakage inductance.

Title: Preventing environment pollution by noxious emission - by extracting dust through gas turbine and collecting in filter
Inventor: FULGER VLADIMIR DIPL ING
IPC: B03C3/00
Filed: 1980-10-02
Abstract: Noxious gases, produced by a factory, are not discharged to the atmosphere through a high chimney but are extracted by an aircraft gas turbine with automatic draught control and a system of restrictor nozzles into a filter building. The combined effect of superheating and electrostatic charge causes the collection of the dust particles in the filter. The dust is extracted at intervals and taken away in enclosed tank trucks. This is a less costly installation than a high chimney.
