Title: Signal coding system for secret transmission - uses transposition of signal frequency with applied pseudo-random bias using locally generated analog signal
IPC: H04K1/00
Filed: 1971-12-09
Abstract: The signal coding and decoding system ensures secrecy of an audio message during transmission. At the transmitter a reference frequency is used to effect a frequency transposition of the signal spectrum. A constant bias of a pseudorandom nature is applied to this for a specified long period, using a locally genrated analogue signal. At the receiver a reference frequency is generated equal to and synchronised with that used at the emitter, using a locally produced analogue signal. This reference signal is used for the inverse frequency transposition of the received signal. The appropriate analogue signal may be derived from a dephased loop controlled by a local clock.

Title: Cross-country ski with foam core protected by rigid (ABS) profiles - to improve the stiffness/weight ratio
IPC: A63C5/12
Filed: 1973-11-13
Abstract: Ski has a low density rigid foam core contained in a thin-wall laminate casing, the sidewalls and underside of the structure being stiffened and protected by 'L' or 'U' section profiles which locate the longitudinal recesses along the lower edges of the body. The upper and lower faces of the ski are covered with thin layers of low friction material. Esp. for cross-country skis. The ancillary profiles allow the overall ski wt. to be reduced by stiffening the outer edges and allowing a lower density core to be used. They also protect the laminate skin from abrasion or puncture. The ancillary profile(s) are pref. made of ABS copolymer by extrusion as constant profiles which may be machined or reshaped to reduce their depth towards each end of the ski. Use of 'U' shaped profile may avoid need for an ancillary low friction cover.

Title: Removal of volatile material from screw feed extruder - by injecting gas into high press. zone of plastic melt and removing it from low press. zone
IPC: B29C48/76
Filed: 1973-12-28
Abstract: Plastic melt (e.g. polyolefine, polystyrene, polypropylene) is fed by a feed screw through a barrel to an extrusion plate through which the melt is extruded, and the barrel has pref. two sepd. seals which delimit a purifying region in which the melt in the upstream zone in at a low press. and the melt in the downstream zone is at a low press. A gas (e.g. a vapour) is fed into the high press. zone and flows through the melt to the low press. zone where it is removed, the gas absorbing the volatile material (e.G. solvent) during its passage through the melt. Pref. water is injected into the barrel through an inlet downstream of the purifying zone and is removed as steam through an outlet downstream of the inlet. Removal of almost all of the volatile material is achieved.

Title: Tractor mounted vine planting machine - drives stakes, plants vines and maintains planting and row distances, straightness
IPC: A01C11/00
Filed: 1974-02-26
Abstract: A plough share opens a trench for the plants in pots. A blade makes a hole for the supporting stake. This is followed by a so-called funnel containing the stake which rests upon a movable stop, and is in contact at its top end with a driving weight. The head of the stake is held in position by a spring. When the stake is turned, the stake point falls upon the ground, and since the machine is moving forward, is driven into the ground. The plants in pots are placed on sloping table and as this passes the place where the stake has been driven. A device hooks onto the stake and allows a plant to slide into the trench adjacent to the stake. A share then follows, covering the plant and the stake. A device gives visual or auditory warning of any divergence in the line of planting.
Patent FR-2266351-A1 (FR)
Title: Stabilised power supply for voltage and frequency sensitive equipment - has standby supply which is not affected by voltage and frequency
IPC: H02J3/38
Filed: 1974-03-25
Abstract: A standby source comprising a rectifier feeding a group of batteries and automatic oscillator has a filter providing a voltage of the same phase and frequency as the supply to the rectifier. A static contactor shunts the standby supply. A detector measures potential and phase differences between the inputs and outputs of the static contractors. A control circuit of the static contactor initiates closing of the contactor in case of oscillator overload when when the measured potential and phase differences remain within predetermined limits. In the case of overload in one of the receiver equipments, the oscillator continues to feed the receiver, but in parallel with the supply, during the duration of the overload.
Patent FR-2239328-A1 (FR)
Title: Injection mould clamping system with lateral motion - to simplify mould design and sustain the injection force
IPC: B29C45/66
Filed: 1974-06-21
Abstract: One half of an injection mould with a parting line parallel to the injection axis is fixed to a support plate while the other half can traverse perpendicularly to the parting line and can be clamped in the closed position by a cam powered independently of the injection force. The fixed half of the mould ensures alignment with the injection system. Cavities are machined perpendicular to the parting line, hence are often cheaper than wedge fitting moulds with an oblique parting line. The locking forces do not detract significantly from the injection pressure.

Title: Woven safety belt has warp yarns of lower stretch capacity - than main weft yarns to indicate wear covsed by tension on belt (SW190176)
Inventor: ANDRONOV M A
IPC: D03D11/00
Filed: 1974-06-27
Abstract: A woven safety belt (e. G for cars) is formed from main warp yarns and main weft yarns and also includes auxiliary weft yarns of lower stretch capacity than the main warp yarns and forming >=1 visible band on the belt. The ratio of the stretch capacity of the auxiliary weft yarns to that of the main weft yarns is lower, pref. by 1-5% than the ratio of the force required to stretch the main weft yarns to the limit to the force required to break the belt. If the belt is highly tensioned during an accident, inspection of the band formed by the auxiliary weft yarns gives an indication of whether or not the belt has been over stressed and is still safe.
Patent FR-2290960-A1 (FR)
Title: Process for applying liquid composition to strips - varies pressure difference between sides of sheet formed from strip
IPC: B05C9/06
Filed: 1974-11-14
Abstract: The liquid is spread over a continuously moving strip, to which items are stuck, by forming a sheet of the liquid by means of a layering device mounted near the strip path, the sheet being maintained between the device and the strip so that it does not move in the direction of travel of the latter. This is achieved by applying gas pressure to the upstream face of the sheet which is lower than a pressure acting on the downstream face. The difference between the two pressures is increased until just before an item reaches the sheet, and then held constant while the item passes across it. The difference is then reduced to the initial value again.
