Title: Drum for mixing and delivering solid materials - has rotating mantle with carriers enclosing transporting and ejecting worm (NL 21.8.79)
IPC: B01F29/63
Filed: 1979-02-16
Abstract: Mixing drum can be rotated in a vertical plane and has on its inner mantle surface, a number of carriers for drawing the material in the drum over a considerable length of its rotary path, and causing it to cascade under the action of gravity. A conveyor is fitted in the drum for filling and emptying the material, and extends though one end face. Inside the drum it is enclosed below by a collector gulley. The conveyor and the gulley extend across the full width of the drum from the one end face to the other, and means are provided for opening and closing the gulley so that it occupies a first and a second working position. Material can thus be mixed continuously and mixed material can be ejected. Used for mixing of relatively coarse matter and powders with very different specific gravities, such as moulding granulates and powdered dyestuffs, as well as fodder for animals and esp. milking cows. The mixer ensures, partic. in the case of fodder that there is no unmixing as the charge is emptied. It is highly efficient, simple to operate and small or large amts. of the mix can be ejected at any time required.

Title: Pilot controlled repeater for analogue transmission system - automatically compensates for changes in analogue signal level
IPC: H04B3/12
Filed: 1979-04-11
Abstract: A repeater (1) amplifiers a range of analogue signals and a pilot signal. A filter (2) passes the pilot signal through an amplifier (3), and a rectifier (4), to one input of a differential amplifier (5). Feedback from the output of the differential amplifier is through a resistor (6) back to its second input. The feedback voltage (V1) is also a function of a fixed reference voltage (Vref). The circuit can automatically compensate for changes in the repeater input signal due to temperature changes in the cable. An alternative version has feedback from the comparator output to the pilot signal amplifier.

Title: Carbo-metallic oil conversion with liquid water
IPC: C10G11/18
Filed: 1980-11-14
Abstract: A process is disclosed for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils. Examples include crude oil, topped crude, reduced crude, residua, the extract from solvent de-asphalting and other heavy hydrocarbon fractions.

Title: Aligning stacks of sheets
IPC: B65H31/34
Filed: 1982-08-03
Abstract: The method of aligning successive stacks of sheets each having a lower portion and an upper portion off-set comprises horizontally feeding each stack with the offset edge of the upper portion leading towards a horizontally disposed sheet separating blade to a position at which the offset edge overhangs the blade. Relative vertical movement between the blade and the stack is effected until the blade has partly lifted the offset edge of the upper portion.

Patent ES-8600556-A1 (ES)
Title: Self-test subsystem for nuclear reactor protection system
IPC: G06F19/00
Filed: 1983-07-26
Abstract: A self-test system for a nuclear power plant, nuclear reactor protection system is disclosed. Nuclear protection systems are the electronic controls, typically including circuit cards, located intermediate between sensors (as for detecting core overheat) and a control (as for providing rod injection to shut down a reactor). Constant surveillance of the nuclear system protection system is provided by a microprocessor that serially addresses protection system circuit cards and loads them at pre-determined input points with test commands. The addressed cards are thereafter simultaneously activated by a system-wide command. The test command is a pulse which is so short in duration that its affect is transparent to the system and cannot cause overall system operation. The pulse passes through the actuating electrical components to verify, on the real actuating path, the operating integrity of the system. After an appropriate response interval, the output state of the system is recorded in system-wide resident registers. Thereafter, with response data contained in these registers frozen at the recorded state, the output is read. This result is compared with the expected output in computer memory. If correspondence between memory output and register output is found, the next sequential set of test commands is acted upon. If correspondence is not found, a subroutine search is automatically conducted to locate the error. The disclosed self-test subsystem is duplicated in four separate divisions with each division testing one of the four duplicate protection systems. The three remaining and idle divisions constantly monitor the active subsystem's operation. The end result is an overall system which reduces the mean time to discover error, thus minimizing mean time to repair and maximizing protection system availability and safety. The separation of the protection system into four duplicate divisions is not dependent on the disclosed invention and the invention may be applied to protection systems with a different number of divisions.
