Title: Electronic signal demodulator which extracts fundamental - demodulates signal from magnetic flux gate and uses narrow band filter
Inventor: POINTET ALAIN JEAN-CLAUDE
IPC: H03D1/22
Filed: 1975-02-26
Abstract: An electronic signal demodulator is used to obtain firstly the fundamental frequency then to demodulate the signal. It is used with magnetic compass flux gates as fitted to navigation systems of aircraft. The unit (A) is connected to a flux gate. It has a Scott transformer which changes three signals into two signals. One of the signals is taken to a narrow-band filter centered on the fundamental frequency, and then to a synchronous demodulator to obtain a signal which is fedback through a modulator. An accurate signal is obtained and supplied to another modulator, and then to a power amplifier. The second signal is modified by a circuit which has the same elements as the first circuit. The two signals from the amplifiers are changed into three signals by a Scott transformer. These signals are used in a unit.

Title: Filter providing multiple outputs - has each output in pulsed form and is adapted for use in multiple loudspeaker systems
IPC: H04R3/12
Filed: 1975-03-10
Abstract: An electonic filter takes a single input and after filtering it provides outputs of different frequency ranges. The design is particularly directed towards systems where the signal is eventually reassembled as in the case of sound reproduction where several loudspeakers having differing responses may be required. The filter has a transfer function h deg. (r)=F(p)/Q(p) where F(p) and Q(p) are polynomials such that Q(p)=pn(A)+F(p). A(p) and F(p) are polynomials of the same degree. Each output line carries bursts of signal proportional to the input amplitude, and the signal free interval includes a fixed amplitude marker signal having a sense inverse to that of the information bursts.

Title: Material testing method using eddy currents - which are generated by AC magnetic field of a fault testing coil
IPC: G01N27/90
Filed: 1976-02-06
Abstract: A fault signal corresponding to a fault in the material is amplified and detected, or impedance change of the test coils is measured, caused by changes in eddy currents induced in the test piece. A feed-back circuit consists of a feed-back amplifier and test coils. Impedance change of test coils due to material fault in the test piece is converted into the feed-back amplifier gain, and the amplifier output voltage is measured or detected, so that a signal proportional to the fault can be collected.

Title: Road vehicle driving control system - has combined accelerator and brake pedal operated by pulling or pushing with foot
IPC: B60T7/04
Filed: 1976-02-25
Abstract: The system for controlling a road vehicle prevents driver drowsiness. The normal compression type vehicle accelerator is replaced by one worked in tension from the driver's foot. Removal of the foot force causes a return to the off position. Should the driver become drowsy, the system is more likely to return to the off position than with the normal system. It also requires frequent changes of body position by the driver. The pedal used can also be employed to actuate the brake, avoiding the need to transfer the foot to another pedal.

Title: Remote detector alarm signalling system - has central control supplying energy to storage circuits in detectors for re-transmission when alarm is detected
Inventor: DUCORNAIT ALBERT
IPC: G08B25/06
Filed: 1976-03-23
Abstract: The alarm and surveillance system uses detectors (4) which are sensitive to a change from a determined state. The system also uses existing conductors (L) as a signal transmission channel. A known frequency signal is generated at each detector (4) in the event of state modification. The signal being identical for each detector. These signals are injected into existing conductors. The signals are received at a single remote unit (5). An alarm is triggered when the signals are received. A continuous signal is transmitted on to the line (L) from the remote unit (5). This signal has a frequency which is different from the detector (4) signal frequency. Each detector receives the signal from the remote unit and stores the signal energy. When state modification is detected, the stored energy is used to trigger signals onto the line.

Title: Continuous mfr. of polypropylene bags with an adhesive closure - using an incompatible strip to cover the adhesive
IPC: B31B19/90
Filed: 1976-12-09
Abstract: Bags incorporating an adhesive strip for sealing the bag after loading are made from continuous lengths, of superimposed or folded sheet by applying an adhesive tape along one edge of a projecting border of the sheet, and then securing an ancillary strip of another sheet along the opposite edge of the adhesive tape, leaving the central third of the adhesive tape exposed. The extra strip is perforated and folded parallel to the tape to cover the central zone of the tape, to prevent anchorage of the adhesive tape while the sheets are transversely welded and cut to produce individual bags. Allows continuous automated conversion of sheet to bags with an adhesive seal, esp. for mfr. of bags from polypropylene sheet ofr film. When ready for use, the ancillary strip is peeled off to expose the adhesive border for sealing the flap of the main bag.

Title: Industrial mfr. of couscous with enhanced output - since prod. does not need screening before drying
IPC: A23L1/168
Filed: 1977-01-24
Abstract: Industrial process and a plant installation for the mfr. of couscous, in which dry ingredients, e.g., semolina, corn flour etc., are mixed with water and the resultant paste is agglomerated, gelatinised and dried. The mixing operation is adapted to produce paste pellets of dimensions which are multiples of the size of prod. required for gelatinisation. These pellets are then reduced to a size suitable for gelatinisation, i.e. of dimensions not less than those of the finished prod. The water content of paste delivered by the mixer should be between 33wt. % and 40wt. %, pref. 35-36%. The mixer is pref. of the pug mill type with twin horizontal beater shafts. The beater blades are set differently in three successive zones, i.e. to push back the ingredients during first zone moistening, to hold the ingredients for a mixing stage in the central zone and to pull off and discharge pellets in the third zone. Reduction of pellet size prior to gelatinisation is pref. effected in a centrifugal granulating mill. Method can be used for industrial mfr. of couscous. The moistening drum process previously employed produced as much as 50-60% of undersize fines which had to be screened out and recycled; frequent blockages resulted in low output.
