Title: Metal bodies lightning conductor - has electrodes inside low pressure gas cylinder short circuited by melting seal during discharge
Inventor: PEAN PIERRE
IPC: H01T1/14
Filed: 1979-10-03
Abstract: The lighting arrester consists of a metal cylinder containing an inert gas at low pressure and chamber with two insulated electrodes at a preset spacing. The electrodes are insulated and sealed into the chamber by a fusible seal. An internal discharge exceeding a preset level melts the seal and the electrodes are pushed together by atmospheric pressure. The cylinder is sealed at each end by a ceramic disc and the electrodes are sealed through coaxial holes in the discs by a fusible alloy. The electrodes contain a pellet of vaporisable material with a low work function such as a barium-aluminium alloy which also absorbs traces of non inert gas.

Title: Assembly system for tubular sections - has internal back to back key inserts which form spigots
Inventor: DURAND JEAN MARIE
IPC: E04F11/18
Filed: 1980-03-12
Abstract: The assembly system requires no clamps or bolts but consists of forming a hole (3) in the main tube (1) to suit the section of the branch tube (2). A profiled wedge (4) slides into position in the main tube directly below the centre line x2-x'2 of the branch tube. Two identical keys are introduced into the hole. The keys are L-shaped and have radiused ends so that they each rotate about the corner of the hole and at the same time are supported on the profile (6) of the wedge. The keys are rotated into the vertical position to stand back-to-back and form a spigot onto which the branch tube fits. If necessary, fixing pins may be screwed through the tube into the spigot.

Title: Lamination of coated foils to plasterboard by using melt adhesives - to suit various interfacial main combinations and minimise setting times
Inventor: HASSENFORDER MAURICE
IPC: B32B13/12
Filed: 1980-03-25
Abstract: Waterstop films or foils for applicn. to paper-coated plasterboard are mounted by fusion of a layer of polyethylene carried on the surface of the film / foil. Lamination effected continuously using a roll nip having a heating tunnel to fuse the melt adhesive coating just before it enters the nip. The roll nip is designed to accommodate variations in the thickness or planarity of the plasterboard base while applying pressure across the full width of the boards. Pref. is also designed to absorb or retain minimal heat from that dissipated by the preheated foil. For applying laminates of aluminium/paper or polyethylene/paper, esp. if further layers are to be mounted, e.g. thermal insulation sheets. The melt adhesive is suitable for foil/paper, paper/paper, or foil/foil interfaces, thus is more versatile than conventional cheaper aq. adhesives ( vinyl or ureaformaldehyde emulsions) which will only bond paper/paper, quicker setting than rubber (neoprene) or resin based (polyurethane) or solvent-based adhesives.

Title: Exhaust turbine driven generator for IC engine - recovers energy from exhaust gases to drive a generator which supplies vehicles electric equipment
IPC: F01N5/04
Filed: 1980-04-04
Abstract: The system uses exhaust gases to drive a turbine which, in turn, drives an electric generator to supply power for ignition, battery charging, fans, pumps, and the vehicle electric system. The turbine (1) is mounted in the exhaust pipe so that the momentum of the exhaust gases (A) is converted to rotation of the turbine. To assist the turbine, partic. at high vehicle speeds, a tapered coaxial duct (3) placed around the exhaust pipe allows the air stream (B) to pass over the turbine blades. An additional application for the generated energy is supercharging, using an electrically driven constant speed compressor on the air inlet. The saving provided by the system is of the order of 10% for engines having a capacity of less than two litres.

Title: Electric opener for bivalve shellfish using oscillating needle - uses AC electromagnet working against spring to oscillate longitudinally needle which penetrates between halves of shell
IPC: A47G21/06
Filed: 1980-04-15
Abstract: The electric opener for oysters and similar bi-valve shell fish includes a needle which oscillates longitudinally to penetrate between the two halves of the shell. An electrically powered vibrator provides drive for the needle. The needle is mounted on the end of a steel rod (5) which is drawn to an elctro-magnet (1) on a.c. peaks and forced away by spring forces (9) at current zeroes. The electric supply is via a cable (11) and is controlled by a switch (12) mounted on the casing (2) of the unit. Two sleeve bearings are provided one (4) next to the electromagnet and the other (8) near the needle exit. The rod is shaped to prevent rotation as it vibrates. To reduce external vibration a rubber sleeve (10) is placed under the spring (9) to provide damping action.

Patent FR-2497544-A1 (FR)
Inventor: PAUL MICHEL VINCENT DE
IPC: F04D29/68
Filed: 1981-01-08
Abstract: The diffuser is symmetrical about an axis AA' and has a flared outer wall (2,3) going from an axial inlet to an outlet. The outer wall is divided into an upstream portion (2) and a downstream portion (3) by a circular bleed slot (1) disposed symmetrically about the axis. The profile of the outer wall is such that, in operation, the direction of fluid flow along the outer wall is from the inlet towards the outlet, both over the upstream portion, and over the downstream portion. Further, it is so arranged that the pressure gradient measured at the surface of the wall and along the direction of fluid flow is negative upstream from the bleed slot and positive downstream therefrom. This ensures that only a small percentage of the fluid flow needs to be bled off to achieve desirable flow conditions, thereby providing good diffuser efficiency.
