Title: Laminated plastic disc for video machine - includes conductive layer which is heated electrically during pressing
IPC: G11B7/26
Filed: 1972-12-08
Abstract: A laminated plastic disc includes a reflective conductive layer (e.g. 1000A thick aluminium film formed by vacuum deposn.) sandwiched between a support layer (e.g. polyethylene terephthalate) and a surface layer (e.g. 1 mu thick polyvinyl chloride film). The disc is pref. preheated to e.g. 50 degrees C and placed in a press so that a current (e.g. 2 amps) can be passed through the conductive layer to heat up the surface layer whilst the surface layer is embossed with a relief pattern.

Title: Cooling incinerator exhaust gas - by introducing atomized liq. suspended in auxiliary gas stream to protect refractories
IPC: F23J15/06
Filed: 1973-05-11
Abstract: In a vertical, cylindrical, refractory, mixing chamber, a rising, vertical, axial stream of auxiliary gas usually atmospheric air, carries an atomised cooling liq. e.g. water, to vapourise as it mixed with a co current, surrounding flow of hot gas. Pref. the auxiliary gas stream is inserted into the chamber with a lower kinetic energy than that of the surrounding hot gas. Pref. also the propn. of cooling liq. atomised into the auxiliary gas stream is automatically related to the temp. of the cooled gas mixt. at the chamber outlet. The process is for cooling very hot gas carrying suspended corrosive agents, partic. powders. The cooler is esp. applicable to cooling exhaust gases from incinerators burning household rubbish, dried sewage etc. from is approx. 900 degrees C is approx. 350 degrees so that the gas can be cycloned to separate entrained solids. The refractory walls of the mixing chamber are protected from thermal shock which occurs if cold liq. contacts the walls. The atomised liquid is centred inside the hot gas flow and with a kinetic energy differential to hold it there. Full vapourisation takes place before droplets reach a wall.

Title: Wind-powered electricity generator - feeds pump transferring water across dam, hydrogen prodn. plant or grid according to demand
IPC: F03D9/02
Filed: 1975-01-20
Abstract: A method of collecting, storing and distributing wind energy consists of using one or more wind-powered electricity generators and using the current produced to pump water upstream of a dam to increase its efficiency. The current is also used in an electrolysis plant for making hydrogen for fuel and for feeding directly the electricity grid when the voltage is high enough. The particular use depends on the supply and demand position at any time. The method allows unlimited storage and use of the energy without any loss of energy, whereas existing methods are too costly to be used on an industrial scale. In addn. it is more efficient than existing methods and less variable in effectiveness. The plant is free from pollution and can be installed anywhere where the wind is sufficient.
Patent FR-2300909-A1 (FR)
Title: Francis turbine with ring around inner blade ring and hub - produces accelerated partial flow to reduce turbulence (SW060976)
IPC: F03B11/04
Filed: 1975-02-11
Abstract: A Francis turbine has an inner shroud (2), an outer shroud (6) and blades (4). As the water flows from the blades (4) vortices tend to form and the efficiency of the turbine is reduced. By fitting a ring (10) around the hub (12) such that the inner surface of the outerwall is parallel to the surface of the hub (12), the outlet area at (b) is less than the inlet area (a) so that the water flowing through the ring is accelerated. This increase in velocity prevents the formation of vortices on the hub (12) and eliminates a cause of energy loss and so increases the turbine efficiency.
Patent FR-2304368-A1 (FR)
Title: Long distance ski harness - holds boot to ski by peg through extended boot sole
IPC: A63C9/20

Title: Easily-assembled cupboard units with panels and edging strips - uses fluid plastics adhesive to fill gaps and lock on solidification
IPC: A47B55/00
Filed: 1975-08-21
Abstract: The knock-down cupboards comprise a basic rectangular frame having elongate edging members (14) which each have a U-cross section to form a base (15) and adjoining side flanges (16, 17). Grooves (20, 21) extend along the edging member (14) adjacent the two side flanges (16, 17) and the frame together with the edging members are mounted with the base at the bottom in a basically horizontal plane wherein a liquid plastics adhesive is added to the edging members so that it flows along and into the gaps between two adjacent elements which are then partially filled. Subsequently the plastics hardens to form a rigid filler which partially fills the depth of the edging members and is locked in to connect all the edging members together. The cupboard is then completed by inserting the edge of the inner side panel into the groove (21) and the edge of the outer side panel into the other groove (20).
Patent FR-2328666-A1 (FR)
Title: Trough for collecting unused glass gobs from furnace - where gobs are quenched to obtain fragments ready for remelting
IPC: C03B19/10
Filed: 1975-10-22
Abstract: The gobs or drops are fed into a vibrating bath of liq., where the combined effects of quenching and vibration burst the gobs to produce the fragments. Vibration is pref. also employed to convey the glass fragments out of the bath, and the pref. device consists of a chassis fitted with skids and spring mountings for a trough which can be inclined at an adjustable angle. The trough is fitted with a vibrator, a drain plug, and overflow plugs used to vary the height of the quenching liq. Appts may also be used for circulating the liq. For example, gobs are drawn from the row of melting furnaces to mfr. bottles etc., but if a breakdown occurs in a blowing or moulding machine, the glass would solidify in the furnace outlet if the glass flow were stopped. The gobs are therefore fed into a trough. The fragments obtd. are small enough so they can be directly remelted without the cost of crushing operations.

Patent FR-2356094-A1 (FR)
Title: Improvements to equipment collecting solar energy - using heat absorbing high carbon organic fluids to collect and transfer heat
Inventor: BOIRON PIERRE
IPC: F24S23/74
Filed: 1976-06-21
Abstract: Improvements to equipment for the capture and retention of solar energy. The heat from the sun's rays is received by an organic fluid circulating in a chamber which is transparent to solar radiation on at least one side. This fluid may be either diphenyl oxide based on hydrogenated triphenyl based with a high carbon content. The heat is stored in a vessel contg. bricks or some natural material immersed in the fluid. The heat storage vessel incorporates a heat exchanger plus a steam circuit to drive a turbine. The fluids used are not transparent to the sun's radiation and they have a high boiling point compared to that of previously used fluids. They can therefore, be used in a circuit at atmos. pressure eliminating the necessity for expensive pressure vessels etc. The high temp. they attain before reaching their boiling point gives a high temp. difference between them and the heat-transfer system thus ensuring fast heat transfer. A particular advantage of using organic fluids is that they are opaque at high temps.
