Patent FR-2047967-A1 (FR)
Title: Injection moulding foamed plastic bodies
IPC: B29C45/58
Filed: 1970-06-26
Abstract: Foamed thermoplastic bodies are produced by a process which avoids gas leaks as well as critical adjustments to the temp. gradient along the extruder axis. The thermoplastic material to which the foaming agent has been added is plasticised below the reaction temp. of the agent and is fed continuously to a transfer cylinder. It is then sprayed from the transfer cylinder into the mould at a temp. above the reaction temp. The increase in temp. is effected in the transfer conduit between the plasticising device and the transfer cylinder.

IPC: G02F1/133
Filed: 1973-05-24
Abstract: Control of the collective orientation of the molecules of a liquid crystal under the effect of an electric field, where the liquid crystal exhibits dielectric anisotropy i.e. having a dielectric constant parallel to the major axis of a liquid crystal molecule which differs from that parallel to the minor axis of the molecule, the anisotropy being characterised in magnitude and sign by (a) selecting a liq. crystal for which two frequencies (F1, F2) exist for which the dielectric anisotropies have opposite signs, (b) applying a first electric field of frequency (f1) to the selected liquid crystal to cause one of the two axes of each molecules to be rotated in the direction of the field (c) thereafter applying a second electric field of frequency (F2) in the same direction as the first field which causes the other axis to turn in the direction of the field. Enables the refractive index to be controlled by controlling the orientation of the molecules of the liquid crystal, for use in optical systems, e.g. colour television, photo-composition etc.

Title: Electrical heart aid pump - handles majority of blood circulation while leaving heart nerves unaffected
IPC: A61M60/411
Filed: 1973-07-20
Abstract: The pump forms part of an extra-thoracic circuit responsible for 70% of the blood circulating. The heart control nerves are unaffected, with edemas disappearing progressively, the tissues disorganised by them reverting slowly to their original state. The system is protected from any electrical or mechanical breakdown, since during repairs all the blood can be diverted to the left auricle by merely rotating the inlet tap. The pump has a metal body with a piston rotating under the control of an electromagnetic motor driven by sets of batteries producing 12 or 24V. The shaft has a helically wound metal strip with five turns to move the oxygenated blood.
Patent FR-2198199-A1 (FR)
Title: Thermomagnetic recording on manganese bismuth film - by local heating and application of external magnetic field
IPC: G11C13/06
Filed: 1973-08-31
Abstract: Thermoremanent recording of information bits on a Mn Bi-film is effected by heating a small area on the film to a temp. above 330 degrees C but below the Curie point, and applying an external magnetic field (0.2-1.2 KOe) which directs the magnetisation of the film in the heated area, but is not sufficiently strong to affect the magnetisation of the unheated parts of the film. Holograms can be recorded because the linearity of the recording process is improved in the presence of an external magnetic field. High bit density is achieved.

Title: Laser beam treatment of bottles - produces local ionisation which prevents settling of e.g. wine deposits
IPC: C03C23/00
Filed: 1974-04-10

Title: Book binding tape using melt adhesives - with integral electrical resistance heater for fusion
Inventor: MIDDLETON BRIAN JOHN
IPC: C09J7/35
Filed: 1975-02-27
Abstract: Double sided adhesive tape incorporating an electrically conductive substrate which acts as a resistance heating element for local fusion of high m.pt. adhesive coatings. If the substrate is porous, viz an open weave fabric or a perforated metal strip, the adhesive coating may be laid on only one face. Used as a tape which may be clamped between two faces to be bonded together and then briefly heated sufficiently to fuse the coating, and if necessary, allow it to diffuse to both faces of the tape. Esp. useful for bonding the spine of a book-cover to a deck of stapled pages or for anchoring toothed profiles to flooring, esp. solid floors, for securing the edges of fitted carpets. Allow use of relatively strong, water resistant adhesives without having to transfer heat through or in depth into the surfaces of the items to be bonded together. Allows bonding of matls. of limited heat resistance with adhesives offering better low temp. crack resistance or water impermeability than e.g. polyvinyl acetate adhesive deposited from emulsions at ambient temps.

Title: Bidimensional image sweeping with surface elastic waves - is performed using semiconductor film below which waves alter conductivity
IPC: H04N3/10
Filed: 1975-04-17
Abstract: Optical acoustic or infra red images are swept bidimensionally by projecting the image onto a semiconductor film below which surface elastic waves are released to alter conductivity. This permits production of the solid state electronic camera. A semiconductor film (4) covered by a transparent electrode (5) is spaced (3) from a piezo-electric substrate (1) below which is a ground electrode (2). The semiconductor film is illuminated by an optical projector and variations are converted to variation of conductivity of the film. Surface elastic waves are transmitted across the film by transducers (6-8) connected to signal generators (9-11) which generate a constant frequency waveform (11) and pulse waveforms (9, 10). A synchronisation signal (9) enables the sweep lines to be distinguished by an output circuit (12).
