Patent FR-2523201-A1 (FR)
Title: Venetian blind for building - comprises pivoting hollow strips containing material which stores energy as latent heat of fusion
Inventor: BIDARD JACQUES
IPC: F24J2/34
Filed: 1982-03-09
Abstract: The venetian blind comprises horizontal or vertical hollow strips (3) which can pivot through at least 180 degrees. The strips have planar or convex faces and contain a material which melts at a temperature above normal room temperature. In one position, the strips are directed towards the window pane, so that the solar radiation melts the material inside the strips absorbing and storing thermal energy as the latent heat of fusion of the material. When required, the strips are pivoted into a second position in which they release their stored energy into the room.

Title: Method of manufacturing a luminescent screen for an imaging tube or the like
Inventor: HAIDER HUGO
IPC: H01J9/227
Filed: 1982-08-10
Abstract: The invention relates to a method of fabricating luminescent screens coated with pigmented luminescent substances with the aid of a suspension, which simultaneously exhibit high contrast, good frame acuity and high luminosity. This is obtained by employing suspensions which have luminescent substances with different rates of pigmentation, the pigment concentration being nearly inversely proportional to the coarseness of the grains of each fraction of luminescent substance, or directly proportional to the surface of the grains. The invention is used, for example, in the manufacture of colour television imaging tubes.

Title: Chord selector applied to the organ.
IPC: G10B3/12
Filed: 1982-12-28
Abstract: First applied to the harpsichord, the present invention, which relates to musical keyboard instruments, may be extended to the organ: the latter will have two similar sets providing different chords. The device, by means of which it is possible to modify the score while playing, comprises a number of registers linked in pairs, with one set being replaced in stages by the other. The accompanying figure gives a plan view of one of these double registers and thus shows the features with their double function: selective function - each of the registers a and b is only partly perforated; alternative function - by a constant amount of offset between the perforations of these registers, their subsequent movement (in this case following the arrow) will incline towards row a the positive situation of row b opposite the engraved numbers 4, 6, 4, etc. With this conversion the organ can play many otherwise impossible intervals.

Title: Hot press moulding by induction heating
Inventor: HICKLING PETER
IPC: H05B6/10
Filed: 1983-08-31
Abstract: The heating system for a press moulding process involves use of a mould made of an electrically conductive matl. clamped between a pair of platens of which one incorporates a layer of electrically excited elements for inducing the secondary field of an induction heating circuit within the body of the mould itself. The face of each platen is covered with a layer of electrically and thermally insulating matl.protected in turn from the mould surface by a thin aluminium plate.- Suitable for use in single or double daylight moulds. More efficient than heat transfer by induction heating of a platen face adjacent to the mould body: allows conventional single daylight mould with induction heating in each platen to be modified to accept two moulds simultaneously, with each heater serving a different mould. By varying the physical spacing of and/or power distribution to selected poles in laminar arrays of poles in the primary induction circuit, the heat distribution induced in the mould body may be varied, e.g. to compensate for heat loss gradients or to induce differential heating to vary the degree of cure produced in matl. in different parts of the mould cavity
