Patent FR-2226195-A1 (FR)
Title: Seesaw game using hydraulic cylinders - pipes connect cylinders to cause opposite action when one is operated
IPC: A63G23/00
Filed: 1973-04-17
Abstract: A game for children uses hydraulic cylinders fitted with flat tops. Pushing down the top of one cylinder causes another to rise, imparting a seesaw motion. Two or more hydraulic cylinders are interconnected by pipping to give a closed circuit. If used outside, the piping and cylinder bases are buried in the ground. Sitting, jumping, or pushing on any cylinder (2) causes an equivalent opposite reaction (1) in the rest of the system. Movements can be varied depending on the piping circuit and the relative diameters of the cylinders. Individual tops, or one large top requiring several cylinders, can be used.

Title: Protection of communication circuit - is for use with microphone and comprises two diodes mounted in series with microphone
IPC: H04M1/19
Filed: 1973-06-12
Abstract: The antilocal protection circuit used with telephone handsets fails to operate satisfactorily when used where noise is of the order of 90 dB. A microphone (M) is connected through a voltage amplifier (A) to the primary of a transformer (T). An ear piece (E) is connected to the centre tap (1) of the secondary winding and to the junction (2) of an impedance (Z) with the line (L). The other end of the impedance is connected to the transformer secondary winding and is meant to have a value equal to the line impedance to eliminate noise from the microphone. Two germanium diodes (or transistors) mounted back to back (D) are connected in series with the microphone. Their dynamic impedance increases with increased applied voltage thus enabling speech transmission in noisy environments.

Title: Automatic lubrication of chain drives - with oil mist lubrication triggered by trip relay action
IPC: B65G45/08
Filed: 1973-07-02
Abstract: An electrical relay is continuously tripped by the links of a chain drive so as to generate an actuation signal for a solenoid operated three way pneumatic valve operating at line pressure (approximately 6 atmospheres). The valve output drives an intensifier to pressurise the lubricant to 120 atmospheres. A number of lubricant ejector valves are fed from the intensifier and are synchronised with the trip relay actuation so as to emit a lubricant mist on the chain rollers. The lubricant ejectors are spring loaded spool valves with a built in non-return valve stage.

Title: Cutting and agitating cheese curds in large scale vats - independently controlled tools follow widely varying paths
IPC: A01J25/06
Filed: 1974-03-19
Abstract: A cutting and agitating device for a mass of curds in a large cheese vat, includes a rotor in the form of a cylindrical housing revolving on a vertical axis, carrying a satellite system with a vertical shaft on which one or two cutting assemblies are mounted; the drives of the rotor and of the satellite system being completely independent of each other. One variable speed motor drives the hollow shaft of the rotor and a second variable speed motor positioned inside the rotor housing, powdered via conductors from a revolving collector, drives the shaft of the satellite system. As a result of the completely independent motions of the shafts of the rotor and the cutters, it is possible to give the tools a path and a speed suitable for any cutting and agitating operation.

Title: Defect detection in metal articles - e.g. pipes, with an impedance probe and an AC bridge
Inventor: NACHBAUR PIERRE
IPC: G01N27/90
Filed: 1974-06-04
Abstract: In an apparatus for the detection of defects in metal articles such as tubes, of the known type comprising a probe with two impedances, which is connected to an impedance bridge supplied with AC; (a) at least one of the impedance arms of the bridge consists of two impedances which can be switched over alternately; (b) one of these impedances comprises one of the two impedances of the probe and the other is arranged outside the probe; (c) the output potential of the impedance bridge is connected to an initial signal treatment sequence, at the output of which two paths of measurement of bridge out-of-balance are provided, arranged in parallel and capable of being switched over alternately; (d) means are provided for switching over the measuring paths alternately and in synchronism with the commutation of the switchable impedances of the impedance bridge and for integration at the output of the measuring paths. In particular, the probe is inductive and its impedances are coaxial solenoids and preferably identical. Permits the use both of a differential measurement for detecting a relative impedance variation of the two solenoids of the inductive probe as well as an absolute measurement, i.e. the detection of a variation of the impedance of either solenoid relative to a reference impedance. This enables slow changes e.g. of wall thickness to be detected as well as defects such as cracks, blow-holes etc.

Title: Reel drive device for fishing reel - has reel shaft reciprocated by spiral groove and cam system
IPC: A01K89/01
Filed: 1974-08-13
Abstract: A housing (a) supports a reel (b) surrounded by a casing (c). The reel core (1) extends into a shaft (3) sliding in a bush (2) integral with casing (c) and supported by a second guide (3'), enabling the shaft to slide freely. A pinion (4) at the base of bush (2) engages in the teeth of a crown wheel (5) located on the perimeter of a disc (6) keyed to a shaft (7) connected to the winding handle.

Title: Brush carrier for small electric motors - has plastics liner providing two friction levels on rectangular carbon brushes reducing physical noise
IPC: H02K5/14
Filed: 1975-05-13
Abstract: An armature brush and brush carrier are used in low power electric motors, the design being aimed at reducing the physical noise and vibration associated with the brush bearing on the motor armature.
