Patent FR-2210882-A1 (FR)
Title: Metal faced laminate - for making printed circuits
IPC: H05K3/38
Filed: 1972-12-15
Abstract: A thin metal sheet adhering to a support base by the application of a predetermined maximum low pressure is assembled with a sheet of uncured plastic material and the assembly bonded under sufficient heat to cure the plastic and under pressure so that the adherence between the plastic and the metal sheet is greater than that between the metal and its base sheet. The base sheet is then removed. The process enables very thin Cu foil, less than 0.02 mm. thick, to be used, the circuit then being built up by "addition". The support sheet is pref. a flexilbe sheet of e.g. cellulose acetate or polyester on which a very thin layer of Cu is deposited chemically and built up to 2.5-17.8 mu by electrolytic deposition. The bond is subjected to a pressure of 0.356-0.89 kg/cm2. The coated support sheet is then pressed against a preimpregnated plastic sheet and bonded in the usual way.

Title: Verifying correct freezing of food prod - using seal that deforms if temp. exceeds upper limit
IPC: G01K11/06
Filed: 1973-07-31
Abstract: Verification that a prod., and partic. a food prod., has been preserved below a given limiting temp. is assured by moulding the prod. into a special indicating shape; this becomes deformed if the temp. rises too high and it can not return to its original shape whatever the subsequent temp. changes. Another form of indicator is in the form of a seal; this is made from body whch is solid below below -18 degrees C and liq. above this temp. It can be made from a mixt. of water and glycol and is frozen in a mould at the same time as the prod. It is then introduced into a plastic pocket with the prod. to be verified so that it can be seen from the outside of the package. If the temp. should rise too high the seal is irreversibly deformed and cannot be re-modelled. Method of verification is easy.

Title: Very high voltage transformer - has winding of conductive and insulating layers around a tube with ferrite core
IPC: H01F5/04
Filed: 1974-03-28
Abstract: The winding is made-up of an electrically conductive strip which is wound with an insulating strip onto the outside of a tube into which may be placed a ferrite core. The conductive strip (1) is a thin sheet of aluminium. The insulating strip (2) is either a layer of plastic material or a layer of the oxide of the conductive strip material.

Title: Cylindrical transformer tap changer - with segmental main and subcontacts, operated by radial link rods running in groove around profiled drive cam
IPC: H01H33/68
Filed: 1974-07-25
Abstract: The cylindrical transformer tap changer has a cam mounted on the rotary operating shaft. The cam circumference has a groove running around it, and one side of the cam is higher than the diametrically opposite side. The ends of link rods locate freely inside this groove so that, as the cam rotates, the rods move up and down. The opposite ends of these radially distributed rods are locked to further arms which operate the contacts switching mechanisms. As the cam rotates, contacts opposite its lower side are progressively closed, whilst those opposite its higher side open. The tap changer retains its switching times, i.e. overlap delay, its contact force and its contact spacing over long periods of time.

Title: Detachable retaining elements for domestic coffee grinder - comprise springs engaging in slots and bracing motor elements etc
IPC: A47J42/38
Filed: 1975-03-14
Abstract: The drive motor and switch elements etc., are fastened to the inside of the machine housing by retaining elements in the form of leaf springs which at one end can be inserted in a slot in the housing and at the other are braced against the part to be fixed. The leaf springs are preferably angled whereby the arms fitting in the housing slot are forked and provided with outwardly pointed barbs at the end, which produces a much more reliable fastening. The relevant parts of the machine can thus be inserted and then secured in position merely by inserting and pressing the retaining elements until they engage in the slots. Similarly the parts can easily be removed by taking a special pointed tool and releasing the springs from the slots.

Title: Insulation jacket for pipes for district heating system - uses ceramic particles suspended in bitumen which becomes pliable when pipe heats up (NO 31.10.77)
IPC: E04H12/28
Filed: 1976-04-07
Abstract: The pipe (1) forming part of a district heating system is provided with a thermal insulation jacket (2). The jacket is produced by surrounding the pipe with a tube (3) of tarred fibre and supported by a platform (7). The annular space between pipe (1) and tube (3) is then filled with ceramic particles (4). Molten bitumen or tar is then poured over the particles either through a funnel (12) or by pumping it through a hole in the platform. When the pipe (1) is in use it operates at a temp. of about 130 deg. which makes the bitumen plastic and able to accommodate thermal expansion without cracking. There is thus no risk of moisture penetrating the jacket and corroding the pipe.
