Patent FR-2147879-A1 (FR)
Title: Two-way tiltable steel works tundish - with asymmetrical tilting axis
IPC: G03G21/00
Filed: 1971-08-05
Abstract: Refractory lined tundish with an depression in the feed melt impact zone and with opposite side positioned tapping lips is tilted round an axis, which in respect to its transverse axis of symmetry is displaced towards one of the tapping lips, so as to permit sufficient tilting over one lip to ensure its being completely emptied. The tundish is placed as near as possible to the tapping lip of its feed furnace. The tundish is for use in steel works and is used for pouring of pig iron and slag into moulds, and reduces metal wastage and permits better process control by avoiding of mixing of subsequent melts.

Title: System for recording numerical programme on magnetic tape - has counter determining period double that of introduction sign, with detection and verification
IPC: G11B20/18
Filed: 1973-10-19
Abstract: The system records or reads back blocks 2 and 3 of numerical information on a magnetic tape in a cassette appearing as signs. Each sign has a certain number of bits, supplemented by a parity bit. Each sign is read twice is succession. An introduction sign is fed in at the top of the block twice in succession. Each sign is repeatedly decoded and they are selected as correct or faulty signs. The parity (6) and identity codes of the sign and repeated sign are verified bit by bit. A counter determines a period twice that of the introduction sign and used for searching. It is detected and produces a recognition signal. The repeating introduction sign is also detected and verified (25 and 26). The decoding and selection controls are synchronised.

Title: Improving combustion in IC engine - by increasing ozone content in combustion air by electrical discharge
IPC: F02M25/10
Filed: 1974-09-05
Abstract: The ozone producer typically consists of thirteen tubes (1) placed inside the intake air filter inlet pipe, which connects directly onto the air filter. Untreated air enters the producer and ozone is produced in each tube by a discharge of about 2800 volts for an engine of 1600 cm3 capacity, each tube typically produces 20mg of ozone per hour. The power consumption is about 25 watts and the fuel saving from 10% to 20%. The power is supplied from the ignition system by fitting an additional coil and an additional spark. The inlet geometry of the producer gives the air additional turbulence at entry.

Title: Flueless domestic gas water heater - has fusible link safety cut out to detect blockage of flue ways
Inventor: CHARRON JEAN-CLAUDE
IPC: F24H9/20
Filed: 1974-09-30
Abstract: The heater has a casing (5) containing a finned tube heat exchanger (1) above a combustion space (4) with a draught limiting flue gas outlet (2) at the top. A gas burner (6) is positioned below the combustion space and a flame failure circuit containing a thermocouple element (15) heated by the pilot flame (16). This circuit also contains a fusible link (3) placed near but not touching the casing opposite a small orifice (17) near the bottom of the casing. In normal operation rising flue gases draw air in through this orifice. If the passages through the heat exchanger (1) become blocked hot flue gases are forced to escape through the orifice and heat the fusible link until it melts and breaks the circuit which holds the main gas solenoid valve open.

Title: WDE BAND SIGNALS TRANSMISSION REPEATER - has automatically controlled frequency response compensating for line losses
Inventor: MAGNERON JEAN
IPC: H04B3/36
Filed: 1975-04-23
Abstract: Transmission of wide band signals such as several television programme channels is a cable distribution system suffers from losses and noise due to attenution and temperature effect. Repeaters with adjustable frequency response equalisers are automatically controlled to equalise cable losses. A repeater comprises a controlled attenuator followed by a connecting attenuator (10) which are both controlled by similr circuits. These control circuits receive signals from a wide band amplifier in series with the attenuators and are timed to a high or low pilot frequency which is detected for comparison with a reference level to define the desired response. Gain controlled amplifiers control the attenuators to null difference signals from the comparators.

Title: DC motor overload protection circuit - is for vehicle window operation and reverses motor operation when obstructed
IPC: H02H7/085
Filed: 1976-02-24
Abstract: Circuit providing protection against mechanical overloads for dc motors. The circuit is especially for motors operating vehicle windows and provides a reversal of the motor operation if the glass movement is interrupted. The circuit is relay based and driven from a transistor and resistor bridge arrangement. Mechanical obstruction is detected by the voltage level across a resistor in series with the motor supply, the resistor preferably being a printed circuit positive temperature coefficient type. Sensitivity can be adjusted by a potentiometer across the first of four transistors a zener diode stabilising the bias circuit. A CR loop prevents motor reversal in the course of momentary obstruction of window movement.

Title: Electrochemical drilling power supply - utilising a negative DC with superimposed negative pulses connected to the electrolyte
IPC: B23H9/16
Filed: 1976-05-31
Abstract: Electrochemical drilling system which uses an insulating hollow electrode through which a highly conductive electrolyte is passed to impinge on a workpiece, has the electrolyte connected to a cathode supply consisting of a negative DC component with superimposed negative pulses. The pulses on the cathode supply provide a ripple which is 75 to 600% of the DC component and provide the sole source of drilling current, while there amplitude is insufficient to cause a spark discharge between the electrode and workpiece. Used to drill extremely small holes in tough metals such as nickel base superalloys. Conventional electrochemical drilling generally produces tapered holes and causes rapid wear of the insulating electrode. Use of pulses produces holes of more uniform dia. and reduces heat generated and the electrode wear.

Title: Protector for undersea pipelines - partic. against damage by ships anchors, incorporates gallery with articulated side-plates, lifting when caught by anchor-bill
IPC: F16L1/12
Filed: 1976-10-11
Abstract: A device for protecting an under-sea pipe-line against the damage caused by ships anchors incorporates plates on both sides of the pipe-line axis parallel to the axis of the pipe, fixed and articulated by their inner longitudinal edges to a sole-piece. The sole-piece is in the form of a longitudinal gallery enveloping the pipe-line. The outer edges of the plates rest on the sea bed while the plates are in the rest position. The length of each plate is about 12 m. Each constitutes an inclined plane over which an anchor moving along the sea-bed, can rise and clear the pipe-line. Difficulties associated with the bill of an anchor sliding under a plate, while the rod to which the chain is attached remains above the plate, are overcome. The plate is lifted in its rotation about its axis of articulation, the anchor rises with the plate until it becomes disengaged from it, but the pipeline is cleared.
