Patent FR-2277480-A1 (FR)
IPC: G01C11/06
Filed: 1974-07-05
Abstract: The system has a first scanner (101) which scans a given area of a first image cyclically so that a scan having a given video pattern is obtained. Photocells convert each video pattern into electrical signals which are fed to a frequency-selective fitter/amplifier (103) which accentuates the components lying in an intermediate frequency band. A quantiser converts the signals from the filter/amplifier into binary reference signals representing a reference image. Output signals are then generated which represent differences between the two sets of binary signals.

Title: Medical headgear production - by folding transverse edges of strip inwards and spreading sides out flat
IPC: A42B1/04
Filed: 1974-07-22
Abstract: The process is particularly for the manufacture of forage-cap type disposable headgear as used in operating theatres, where a strip of paper or non-woven cloth is folded along three lines in the lengthwise direction to form it into an M, section. The strip is then parted off transversely into the desired length and the transverse edges are joined together. Each transverse edge (4) is then folded inwards, while at the same time the cap sidewalls (5) are spread out flat, so that each transverse edge coincides with the concave lengthwise fold line (2) in the centre. Each transverse edge is then secured in place by folding the walls on each side into an isosceles triangle.

Title: Preventing lime deposits in the tubes of multipoint heaters - continued flow after shut off prevents reaching critical temp
IPC: F24H9/20
Filed: 1974-12-16
Abstract: A method of preventing the formation of lime deposits from hard water in straight through heaters giving instantaneous hot water; the deposits being caused by the momentary overheating of the residual water when the feed is cut off, uses a reserve vessel to create a continued greatly reduced circulation of water. Connections to the vessel are arranged so that, as it acts, when the through-flow control valve is closed and the gas feed to the main burners is cut off, the flow of water is continued for a definite short period in such a way that the safety valve for preventing dry running, is not opened. Prevents the formation of alkaline stone deposits tending to block the tubes, by preventing overheating of the remaining water in the coil when the flow is stopped.

Title: Pressure relief valve for air pump - uses elastic sleeve around piston rod to open ports at excess tank pressure
IPC: F04B53/12
Filed: 1975-05-21
Abstract: The air pump consists of a cylinder (1) mounted inside a tank. The piston (2) is formed integrally with the piston rod which extends through the end cap. The lower end of the cylinder (1) is provided with a non-return valve (6) which allows air to flow into the tank but prevents its return. The piston rod is provided with a blind hole (8) which communicates with four radial holes (9). These holes are normally sealed by an elastic sleeve (10). When the pressure in the tank exceeds a safe value, the elastic sleeve expands and allows air to escape in the upper part of the cylinder (1) which communicates with the atmosphere.

Title: Logarithmic mechanical calculator to any base - uses three chronometers and electromagnet ratchet beam mechanical system
IPC: G06G3/04
Filed: 1975-07-16
Abstract: The mechanical system determines step by step the logarithmic function to any required base of a numerical value evaluated between two limits. The system associates means designed to detect the equality between the instantaneous value of the variable and the product of the absolute value of the variation of the variable, with a former value having a positive and fixed coefficient greater than unity. The equality is used to define the variation of a part of the fixed value of the logarithmic function to be determined. The system uses three chronometers (1, 2, 3) each fitted with hands (4, 5, 6) having contacts on them. Press in winders (7, 8, 9) actuate a successive sequence of operation when pressed. It also has an electromagnetic system (19) which controls a beam-rachet (22, 23, 24) mechanical device.

Title: Improved secrecy of scrambled signals transmission - uses scrambling and unscrambling control by corresponding key signals (NL040576)
IPC: H04L9/12
Filed: 1975-11-03
Abstract: The scrambling on the transmitter side and the unscrambling on the receiver side is carried out by coinciding keying signal on the transmit and receiver sides. The sequence of sending and receiving end key signals is simultaneously and similarly changed by at least one switching operation. The receiver switching is tripped by a switching pulse train, transmitted in periodically recurring gaps in scrambled signals. The sender switching is delayed, so that both switchings are simultaneous. Preferably the switching results in at least two keying signals to become effective in coincidence on the transmit and receiver sides.

Title: Transportable vibrator for clearing trucks - has electromagnet to couple to metal truck used at mineral workings (PT 24.8.76)
IPC: B65D88/66
Filed: 1975-11-19
Abstract: The trucks running on the mine railway are cleared of sticky fragments by coupling a vibrator to them. Usually the vibrator has been connected at a special point of the truck, where one half of a coupling has been fitted for it. In the new arrangement, the coupling is by an electromagnet (2) connected to the vibrator (3). Not only does this render the special fittings on the trucks unnecessary, but it allows the vibrator to be applied at whatever point of the truck current experience suggests is best. The vibrator and magnet are mounted on a wheeled trolley (6) and are operated by mains electricity.

Title: Tubular electrical heating coil for flow processes - uses fluid which is passed through coiled tube coupled to electrical supply (NL161176)
Inventor: HALONEN TUOMO
IPC: A23L3/005
Filed: 1976-05-12
Abstract: The high efficiency rapid electrical heating system utilises a tubular coil coupled to an electrical supply and is well suited to milk pasteurisation processing. The fluid is pumped, (5) through a coiled tube (1) to raise the temperature rapidly to 80 deg.C. To increase efficiency and utilise the energy of the system to give the best effect, the output of the coil is fed to a heat exchange (4) and then to output.
