Patent FR-2227976-A1 (FR)
Title: Turning indicator for cars and trucks - with improved control and operation electric circuit
IPC: B60Q1/38
Filed: 1974-04-18
Abstract: The two left and right lamps are controlled by a 3-posn. switch. The closing of a normally open relay contact brings the power to the switch and excites the oscillator which includes a delay control condenser. The oscillator controls the relay wiring and operates its contact. A first-stage transistor is a conductor when switch is closed and condenser charge lower than threshold value and another transistor which is not conductor unless the first is excited. The excitation of the relay winding and condenser's charging is done by exit transistor. Preferably, means to alter oscillation frequency when one or two lamps are out of order are available.

Title: Drain pipe sheathed with filter material contg. ion exchanger - to prevent clogging by iron ocher pptd. from the drainage water
IPC: E02B11/00
Filed: 1974-10-18
Abstract: A drain pipe has a sheathing contg. solid ion exchanger (known per se) which may be an acidic resinous ion exchanger or black peat, in granulated form. The action of the ion exchanger prevents formation of iron ocher pptd. from iron-contg. water in the soil in which the pipes may be embedded. This would result in clogging the sheathing and prevent efficient draining action. The sheating may be a filter material, known per se, e.g. foamed polystyrene in which the ion exchanger is embedded. Alternatively, the sheathing may comprise at least 2 fibrous layers with the solid ion exchanger interposed.

Title: Plastics wing nut for holding vehicle air filter cover - has sealing flange and self-tapping bore force fitted over threaded stud projecting through cover
IPC: F02M/
Filed: 1976-01-13
Abstract: A plastics wing nut for fixing the covers of air filters on motor vehicles has a head with a screwdriver slot (7) and two wings (1, 2) below which there is a tubular extension (3). At the lower end of the extension, a flare or washer (4) is integrally formed and below that, a boss (5) with a concial external face (6). The bore of the tubular extension is less than the external diamete of the threaded mounting spigot (9) of the filter unit and the hole in the cover (10) is such that the cover will rest on the shoulder (11) of the spigot and be retained by the conical portion of the nut extension. Removal of the nut is by unscrewing in the usual way. A variant employs two hooks (12, 13) in place of the boss so that the nut can be assembled to the cover before fitting to the filter.
Patent FR-2298849-A1 (FR)
Inventor: FOURCIN ADRIAN JOHN
IPC: G09B5/00
Filed: 1976-01-23
Abstract: 1533112 Speech pattern derivation LARYNGOGRAPH Ltd 8 Jan 1976 [24 Jan 1975]  3269/75 Heading G1N(E) [Also in Division G5] In a laryngograph for monitoring the vocal fold vibrations in a speaker's larynx in speech training &c., a single frequency oscillator, Fig. 2, or a broad band oscillator, Fig. 3, supplies a carrier wave to a transmitting aerial positioned adjacent the larynx. The modulated carrier wave is picked up by a filter further adjacent aerial whose output is detected 3, Fig. 2, or demodulated 8, Fig. 3. The result is filtered 6 to produce a vocal fold waveform Lx representative of the "voiced" sounds in each utterance. The carrier wave level is maintained constant by two alternative types of feedback system controlling the oscillator 2 or the detection circuits (which may employ slicing techniques). The electrode aerials may take the form of a standard printed circuit board which is etched to produce a circular element with a concentric ring spaced therefrom. Larynx waveform L X  displays and vocal fold vibration determination. The signal from the filter amplifier 6 is fed via a band pass filter 40, Fig. 4, which supplies an amplitude sensing circuit 51  connected to a memory input control 52. The control 52 controls the input pulses, from a clock 50, which are gated 48 under the control of a closure pulse generator 42, supplied, as shown, by an infinite clipping circuit, to provide a uniform pulse for each larynx closure. This enables pulses to be counted 49 to give a measure of the vocal fold vibration period Tx which is eventually stored in a main memory 54. The pulses from the counter 49 are directed by the control 52 into a random access memory 54 connected to a display unit 57. The signals reaching the display must be logarithmically converted at 56, or at any other convenient point in the system. Alternatively, suitable non- linear clock pulses may be used. A chart recorder 45 or a "X-Y" plotter may feed the memory via a buffer memory so that only voiced segments of the speech are drawn slowly, while intervening voiceless pauses are moved over quickly. In a further embodiment, Figs. 6 and 7 (not shown), the characteristic frequency in two frequency bands F 1 , F n  are shown on a stored display with a colour distinction between parts of an utterance which are voiced, fricative (consonants) or voiced fricative in form.

Title: Automatic catch for tipper flaps - has sprung arm for linking to tipping axis and securing when not tipped
Inventor: CAGAN JOSEF
IPC: B60P1/26
Filed: 1976-03-10
Abstract: The tipper surface is linked to the tipping axis by two interlocking segments. An upper segment (4) linked to the surface pivots on a lower segment (1) linked to the chassis. The lower segment is coupled to the release catch (8) for the tipper flap (9) by a spring loaded arm (7). As the load surface is tipped about the axis the spring loaded arm pivots relative to the load surface to release the catch. It is secured when the tipper is dropped, with the flap closing under its own weight. The system can be used on both rear and side tippers, and on combined axis tippers. It relieves the driver from having to leave the driving position every time the load is tipped.

Title: Telegraphic transmission of processor information - employs electronic switching circuit to transmit binary information to distant peripheral
IPC: H04L25/00
Filed: 1977-05-03
Abstract: The electronic switching circuit is used for telegraphic transmission of information from a processor to distant peripheral equipments such as a teleprinter. Information is transmitted in binary form and includes circuits to eliminate disturbances from 50Hz voltages. A constant current generator (G1) produces a signal when commanded by control circuit (CD). The current flow is indicated by a monitoring circuit (MI). The constant current signals are applied to two identical switching circuits (T1, T2) whose outputs are applied to two transistors (T7, T8) whose bases are switched by a multivibrator (NB). The switched outputs are applied via capacitors (C1, C2) and diode bridge circuit (D3-7) to the lines (1g1, 1g2) to a peripheral equipment (TY).
