Title: Fiberising glass using orificed centrifugal spinner - feeding glass to spinner via rotating basket with single row of apertures
Inventor: BATTIGELLI JEAN
IPC: C22C19/05
Filed: 1979-06-22
Abstract: In fiberising moltent glass by the centrifugal projection of streams of glass through rows of perforations in the peripheral wall of a spinner positioned on an upright axis within a downwardly directed annular gas blast, all the molten glass is feed to the inside of the peripheral wall of the spinner in the plane of the uppermost row of perforations. An downwardly flowing layer of glass is thus formed on the inside of the peripheral wall of the spinner. A rotating distributing basket with a single row of apertures in its peripheral wall located in the plane of the uppermost row of perforations of the spinner is located in the spinner wall. Used for fiberising glass, mineral and other thermoplastic materials.

Title: Perpetual motion machine using gravitational force - uses group of weights supported between two discs with separate axes so that weights are held such that net forces are asymmetrical
IPC: F03G7/10
Filed: 1979-06-20
Abstract: Mechanical rotation is obtained from gravitational force, or alternatively buoyancy, using a group of equal weights (or floats) mounted between two vertical discs whose centres are vertically displaced (D). The weights are cuboid and mounted to discs by pivots (6) mounted one at one corner of the cuboid and the other mid-way down one side. This form of mounting causes the weights to be held outside the radius of the discs when on one side of the disc centre line and, when diametrically opposite, the weights are held inside the radius of the disc. The weights therefore exert a greater torque on the discs on the down side than the torque required to raise the discs in their upward travel, giving a net rotational torque. The appts. may also be made to function under constant pressure in a liquid.

Title: Waste heat recovery system for heat engines - uses exhaust gases to drive turbine to circulate working fluid and drive heat pump compressor
IPC: F02B41/10
Filed: 1979-08-17
Abstract: The waste energy from heat engines, partic. petrol and diesel engines, used to drive emergency electric generators can be used for heating purposes. Emergency generators are usually automatically switched in with automatic starting of the heat engine. Heat can be extracted from the cooling water by a heat exchanger and from the exhaust gases by a gas heat exchanger. In addition the kinetic energy of the exhaust gases can be used to drive a turbine, which may be used to drive a pump to circulate the working fluid used in the air heating of factory, office or domestic prmises. Heated working fluid may be stored for use while the heat engine is not running. The exhaust turbine may also drive the compressor of a heat pump which may advantageously be driven from the electricity supply network at other times.

Title: Polymeric replica films of specimens for electron microscopy - formed directly on the surface of specimen by plasma polymerisation of organic monomer vapours
Inventor: TANAKA AKIRA
IPC: G01N1/28
Filed: 1979-12-18
Abstract: A replica film of a specimen for electron microscopy is formed by forming a polymer film of uniform thickness directly on the surface of the specimen by plasma polymerisation of organic monomer vapours by a glow discharge method. Suitable organic monomers are e.g. ethylene, propylene, benzene, toluene, xylene, styrene, chlorobenzene, 1,2,4-trichlorobenzene, ferrocene, ethylbenzene, ethylene chloride, propylene oxide, methyl methacrylate, n-butyl methacrylate, 1,2-epoxybutane and 1,2-epoxyethylbenzene. Process allows uniform replica films to be deposited on substrates such as biomedical specimens. The replica films are amorphous and allow electron microscopy of much higher resolving power than is obtainable e.g. using deposited metal replica films, in which the grains affect the resolution power.

Title: Tubular glass ampoule contg. liq. fixative for protozoa - which is instantly discharged under gas pressure in space experiments
Inventor: TIXADOR RENE JEAN PIERRE
IPC: A61J1/06
Filed: 1980-04-02
Abstract: Tubular glass ampoule has a 180 deg. bend of tight radius. One end of the bend is extended with a short branch and the other with a much longer branch parallel to the first. The short branch and a length at the outer end of the long branch are both filled with a gas or vapour under pressure, a column or liq. to be ejected being sandwiched between the two gas pockets. Fracture of the ampoule at any point allows all the liq. to be quickly ejected under pressure of gas. Pref. the liq. is a mixt. of which one constituent has a high vapour pressure at ambient temp. the liq. is pref.. a fixative for protozoa, in the form of a mixt. contg. a major proportion of formol with minor proportions of acetic acid and ethyl ether. In particular, the liq. pref. contains 84 to 86% by wt. of formol, 4 to 6% of acetic acid and 9 to 11 of ethyl ether. The ampoule is used for biological experiments in outer space, the liq. being released at a selected time for immediate fixation of protozoa such as paramecium. Multi-sample experiments carried out at time intervals allow rate of cell growth in space to be compared with that of control samples on earth. The time of fixation is essentially the time of fracture of the ampoule because the liq. is instantly and fully discharged on fracture.
