Patent FR-2377595-A1 (FR)
Title: Refractory lined chamber for molten material - e.g. converter or electric furnace, with improved arrangement for heating the refractory lining
Inventor: FLOCH JEAN LE
IPC: F27D1/18
Filed: 1977-01-13
Abstract: A refractory lined enclosure for receiving molten material has the refractory heated to high temp. by combusted gases. The enclosure is provided with an air-cooled cover which mixes the air with exhaust gas emitted by a burner secured to the cover. The cover then directs the mixed gas, after its passage through heat exchangers, towards a second enclosure concentric with the first. The assembly enables the consumption of the gas required for combustion to be reduced. In addition the assembly allows the use of gases of lower combustibility than conventionally, enables surveillance devices to be installed in the cover and enables the gas to be ignited electrically. The enclosure is e.g. a converter or electric furnace.

Title: Electrode for effluent coagulation - composed of electrically conductive shavings compressed into blocks
Inventor: MIQUEL JACQUES
IPC: C02F1/461
Filed: 1977-01-17
Abstract: An electrode is composed of shavings of an electrically conductive material compacted into a block. The block is strengthened by binding it with metallic strips of the same material as the block. The electrode is produced by impregnating the shavings with oil and then compacting them. Used in the coagulation treatment of waste water and other effluents, the electrodes dissolve peripherally and not internally which would cause their disintegration.

Title: Two phase logic clock source - is based on cross coupled NAND=gates driven from common source
Inventor: BOURDERIAT JEAN-LOUIS
IPC: H03K5/151
Filed: 1977-01-28
Abstract: The clock source is for logic circuits where high precision timing is required, the design requiring a min. number of components without reduction of performance. The circuit is driven from a single source clock whose output is split into two parallel channels feeding two cross coupled NAND or NOR gates (2, 3) one of which has an inverter (1) in its input line. Each gate has a third input point to permit sampling signals to be fed in, the gate outputs feeding two directly coupled inverting amplifiers (m1, m2) which provide buffering and matching into the load circuits. The entire circuit may be monolithic and built onto a common substrate or built up from discrete components.

Title: Modules of aluminium silicate for insulating furnace walls - are built up from folded layers of fibres
Inventor: BLONDEAU MICHEL HONORE
IPC: F16L59/02
Filed: 1977-04-21
Abstract: The walls of furnaces which operate at temps. in the range of 800-1500 degrees C are insulated with modules of fibrous material such as aluminium silicate.

Patent FR-2353328-A1 (FR)
Title: Filter for removing trash from fibres fed to spinning machine - can be rotated to allow cleaning during filtering operation
IPC: B01D46/02
Filed: 1977-06-03
Abstract: A filter for removing trash from fibres moving in an air flow to an open end spinning machine includes a suction duct surrounded by a rotatable cylinder internally of which are mounted filters. The cylinder is mounted in a chamber through which the fibres pass and is divided internally into four sections by radial walls. Air passes radially inwardly into the suction duct through a section so that trash collects on the filter in that particular section. When a filter of a particular section is blocked, the cylinder can be rotated so that the blocked filter is adjacent e.g. a door in the chamber and can be cleaned. Meanwhile filtering continues through another section. The filter is cheap and allows filtering to continue whilst it is being cleaned.

Title: Inking zone helix movement mechanism - has reciprocating driving member coupled to helix shafts and contacting limit switches at ends of stroke (SW 23.1.78)
IPC: B41F31/04
Filed: 1977-06-27
Abstract: The mechanism gives definite movement of a set of helices in the inking zone of a printing press, having a driving member to which the various helices can be coupled as desired. The member performs a reciprocating movement, being typically a sliding bar which can be coupled to the helix shafts, and of variable speed. The number of its movements can serve as a measurement of the amount of helix movement, the connections made for each direction of movement can be effected by limit switches in the path of the driving member. The design combines simplicity with low power consumption and high travel speed.

Title: Self levelling frame for portable building - has roof portal with telescopic legs demountably fixed to those of floor portal
IPC: A63G4/00
Filed: 1977-12-14

Title: Numerical display of randomly variable quantity esp. radiation level - is stabilised by making changes in display dependent upon repetition of changes in readings
IPC: G01T1/18
Filed: 1978-01-11
Abstract: A method of measuring and numerically displaying a value which is characteristic of a weighted flow of a random character is intended esp. for measuring and displaying a variable intensity of radiation in a manner which can be readily observed and interpreted. Signals from a transmitter represent the instantaneous count rate of the random events and are received by a counting device, from which they are transmitted to the numerical display indicating the value or intensity in a period (T). The value (I) emitted by the transmitter and characteristic for the weighted flow rate or intensity of a very short period (T) is compared with the value (R) which is characteristic of the reference weighted flow rate or reference intensity of one of the preceding very short periods (T); the display is only modified when (I) differs from (R) in the same sense in a succession of one or more comparisons. Specific. a time interval (n DELTA T) is defined, n being a whole number and DELTA T a predetermined fraction of the period (T); the display is only changed when equality becomes established between the values (I) of the instantaneous intensity and (R) of the reference intensity on a number of occasions exceeding one in the same sense outside the time interval (n DELTA T). Used in particl. for displaying radiation levels and other variable signals on board an armoured or shielded vehicle. By smoothing out the readings to produce a stabilised indication, visual observation of the display is made easier.
