Title: Calorimeter for radiator pipe - has flowmeter coupled to differential thermometers
IPC: G01K17/14
Filed: 1974-08-23
Abstract: A flowmeter or a water consumption meter measures the quantity of liquid in circulation in a pipe, and two metallic thermometers (1) measure the temperatures at two different points of the pipe. The temperature difference at these points is reflected in rods (2, 3) which rotate discs (8) in opposite directions about an axis (4). These discs (5) rotate a second disc and turn it about the axis (4) with a toothed sector (7) which drives, in parallel, a toothed rule (8) and a third disc (9) which moves freely along the axis of a recorder (10) while remaining in contact with a fourth disc (11) which is linked to the flowmeter. Thus the number of revolutions of the third disc (9) is proportional to the produce i.e. the heat loss and is recorded on the recorder (10).

Title: Natural energy heat-pump heating or air-conditioning - with vaporiser linked to energy source, and condenser to energy store
IPC: F24D11/02
Filed: 1975-03-07
Abstract: The heating and/or air-conditioning installation for use in buildings is designed to make use of natural energies, such as solar heat, terrestrial heat, or groundwater or district heating waste heat, to be brought to the requisite temperature, using a heat pump with a condenser and one or more vapourisers. The latter are in operative contact with the energy distributing medium, and the condenser with an energy-conserving storage unit. Controlled energy transmission to the building, or to individual rooms, is carried out exclusively from the energy store, and a further vapouriser can be incorporated into the circuit following the energy store, for cooling. Energy supply to and from the energy store maybe exclusively via heat exchangers. The energy store, preferably water filled, may comprise chambers interconnected at top and bottom, with heat given out at the bottom of one and taken up at the top of the other.

Title: High voltage transformer with coolant oil duct - lined with non-woven felt of fibres of terephthalate (co)polyester of ethylene glycol and/or propane diol
Inventor: ABGRALL FRANCOIS
IPC: H01F27/32
Filed: 1975-04-10
Abstract: The transformer has a series of electrical windings around e.g. a central insulating support and a channel for circulating cooling oil through the windings. The channel is delimited by layers of an insulating solid felt formed from fibres of a (co)polyester of terephthalic acid and ethylene glycol and/or propane diol. The insulating felt absorbs the oil and has a permittivity close to that of the oil, thereby reducing dielectric losses. For the same thickness of conventional insulation the voltage across the windings can be increased. The felt is strong.

Title: Crimped covers for goods stacked on pallets - from folded double-walled film, shrinking parallel to pallet surface
IPC: B31B160/20
Filed: 1975-12-03
Abstract: A method of producing crimped covers for goods stacked on a pallet, uses a folded double-walled film, and applies close to the fold, two inclined welded seams, spaced at a distance apart corresponding to the width of the cover when flattened out, in the form of a "V", the point of which is aligned to the fold or joins it. The triangular section between the legs of the "V" is cut away, and from the bottom point of the "V", a vertical welded seam is run across the film, and the cover is cut from the length. Method forms the shrink-on cover with less material, lieing smoothly against the stack, without pleats or other projections which can catch those of neighbouring loads and cause damage.

Title: Reciprocating water powered engine - has two buckets moving in opposite directions and connected by chain held by sleeves with valves for closing buckets
IPC: F03C99/00
Filed: 1975-12-10
Abstract: The vertical framework has four guide rods (7) on which two buckets (8, 9) can move up and down. A sleeve (15) sliding over a central shaft (12) carries a valve (16) which closes the lower bucket at its bottom and has a flange (18) at its top which holds one end of a chain (19). An outer sleeve (20) similarly carries a valve (21) which closes the upper bucket and a flange (23) holding the other end of the chain. The chain passes over a wheel (5) at the top of the frame. Water falling into the top bucket pushes it down which pulls the other one up. When the bucket reaches its stops (24) the valve opens and releases the water into the lower bucket. The motion then reverses.

Title: MATERIALS OF HIGH ELECTRICAL RESISTANCE AT HIGH TEMPS. - comprise crystalline thermoplastic (co)polymer and conducting filler used for heating elements
IPC: C08L101/00
Filed: 1976-08-03
Abstract: PTC materials (having a positive temp coefft. of electrical resistance) comprise a crystalline thermoplastic polymer having a gel fraction of 0.60-0.885 and a finely divided electrically conducting filler. Used for prepn. of strip heating elements which automatically switch off at a predetermined "switching temp", Ts. It has been found that the specific resistance of cross linked polymeric PTC materials on heating above peak temp remains constant only over a small temp increase. The resistance falls considerably on further heating and results in high energy prodn. from the electrical power source and runaway heating which can have disastrous consequences. This problem is avoided by crosslinking in such a way that the gel fraction of the polymer remains within the range claimed. The polymer used should have at least 10% and pref. 20% crystallinity as determined by X-ray diffraction. Pref. polymers are (co)polymers of C2H4, propylene, butene-1 and hexene-1 or copolymers of C2H4 with methacrylic acid, ethyl acetate, vinyl acetate or fluoride, polyoxy-methylene, ethylene or -propylene; polyvinylidene fluoride; polyphenylenesulphide, polymethacrylonitrile; polycarbonates, and polyimides. The conducting filler is pref. C black, but finely divided metals can also be used.
