Patent FR-2206163-A1 (FR)
Title: Moulding plastic layer onto support fabric - using removable core to provide an aperture in the finished article
IPC: B29C43/18
Filed: 1972-11-13
Abstract: A plastic material (e.g. PVC) is applied in liquid or paste form to a mould in which a polypropylene or polypropylene deriv. core (e.g. a rod) is located, and the plastic material is melted by a high frequency electric field whilst a support fabric (e.g. leather) is pressed against the plastic so that it is bonded to it. When the laminated plastic/support fabric structure is removed from the mould the core is also removed thereby leaving an aperture in the structure. Pref. an absorbent material is sandwiched between the support fabric and the plastic. The method is used partic. for making watch straps. The apertures are easily formed since the polypropylene core has a higher m. pt. than the plastic.

Title: Massage apparatus synchronised to heartbeats - has variable frequency signals fed to magnetostrictors or fluid solenoid valves
IPC: A61H23/04
Filed: 1974-01-24
Abstract: The apparatus messages a patient's limbs by means of magnetostrictors in contact with the skin. Alternatively, solenoid valves may be used to control fluid impulses into pressure bands around the limb. It is operated automatically in synchronisation with the patient's heartbeats these being registered (8) and amplified (9). The signals are passed into dephasing units, to control the time delay before the magnetostrictor or solenoid is operated; this delay is adjustable. The basic frequency is divided and varied by adjustable multivibrator units (16, 17, 18), this frequency being selectable (19). The resultant signals are amplified (20, 21, 22) for use, switches (23, 24, 25) permitting selective use of the apparatus on the limb.

Title: Rotary internal combustion engine - runs on oxygen hydrogen mixture obtained from nuclear dissociation of water
IPC: C01B3/04
Filed: 1974-05-21
Abstract: The engine has a water container in the base of which is a hollow aluminium annulus contg. boron hydride which is in a self sustaining gamma radiation state the radiation from which dissociates the water. The resulting gases collect in a funnel and pass to one of three combustion chambers equally spaced round the periphery of the stator. A central vertical shaft carries a rotor with water filled bucket shaped spaces. The water produced by combustion in one chamber collects in these, forces the rotor round and compresses the gases in the next chamber before they are ignited before itself returning to the water container. The engine is started by a guided laser beam which initiates the gamma radiation.

Title: Automatic production unit for non-destructable packaging - package is formed from one piece by folding and use of adhesive only
IPC: B65D75/14
Filed: 1974-09-16
Abstract: The packaging is esp. for rectangular objects, e.g. a book or record. It is formed by folding a flat blank, with pre-drawn fold lines.

Title: Railway pressure operated brake actuator - has axial piston motion transmitted to linear through radial bladed rubber diaphragm
IPC: F16D65/14
Filed: 1974-09-25
Abstract: Pressure operated brake actuator for rolling stock that has a ring-shaped piston capable of axial movement in a ring-shaped or hollow cylinder. Movement from the piston is transmitted through a system of radially arranged levers. These levers have rubber blades moulded to their sides so that the whole arrangement is shaped like a diaphragm. The inner end of each lever rests in a groove of the moving piston while the outer end of the lever fits in a similar groove in the cylinder wall which forms a pivot point. An intermediate spring loaded ring is in contact with the middle section of the lever. Movement of the piston results in a pivoting motion of the levers which in turn is converted into linear motion of the intermediate ring that operates the brake rod.
