Title: Battery charging circuit with voltage sensor - uses current transformer and thyristor to control current charging conditions to safeguard battery
Inventor: VIOLANTE FELIX
IPC: H02J7/00
Filed: 1975-01-24
Abstract: This charging circuit for use either on vehicles or for stationary charging, has a main control thyristor (Thl). The charging rate is detected by a transformer whose primary winding is energised by the charging current and whose secondary winding excites a photo-diode. The illumination from this diode acts upon a photo-sensitive resistance (PhR) and an NPN transistor driving a unijunction transistor (T3). The latter transistor controls the thyristor. An end-of-charge' circuit is provided which consists of a diode protected voltage sensor acting upon a relay in the thyristor trigger circuit. This circuit gives control of average charging rate to prevent battery damage.

Title: Anti-tank mine with vibratory rod - has control system which analyses vibrations to explode mine
Inventor: PRIOU STEPHANE
IPC: F42C11/00
Filed: 1975-07-07
Abstract: An anti-tank mine has a body (1) which is inset into the ground, with a central hollow recess (2) above which is mounted a flexible rod (3) of metal or non metallic material, with one end free, which when contacted by a tank, explodes the mine. The effect of being contacted vibrates the rod, and the vibrations operate a control device which in turn explodes the mine. A transducer converts the mechanical vibrations into electrical signals, which are fed to a circuit including an analyser used to compare the length and magnitude of the signals with reference signals to activate the explosion. The rod can be coiled for mine laying by a suitable vehicle. The transducer may be at the bottom of or at the free end of the vibratory rod.

Title: Planar integrated circuit with at least one layer of contacts - uses two different insulating layers for selective removal by etching agent
Inventor: RIOULT JEAN-PIERRE
IPC: H01L21/311
Filed: 1976-02-20
Abstract: The planar type integrated circuit has on one active face of a semiconducting chip at least a first bed of first-insulating material. During mfr. a window is formed in the insulating material. This window is designed for the formation and connection of active and passive elements of the integrated circuit. The first bed is covered by an intermediate protection layer of second insulating material, and an aperture is formed in the layer. A third layer of a different insulating substance to the second is deposited. This third layer (a) is is susceptible to attack by an agent which remain inactive with respect to the second material. By means of a mask and the agent an opening is created in the third layer. The opening clears at least on a part of the periphery of the aperture, an area of the second material. Afterwards a metallic film is deposited on the chip. Then after eliminating the mask, sheets of the metallic film are removed from the mask.

Title: Removing radioactive wastes from nuclear power station - using addn. of binder to effect solidification after filling into containers (SW181076)
IPC: G21F9/16
Filed: 1976-03-19
Abstract: A process for removing radio-active wastes from a nuclear power station consists of filling them into containers, adding a binder capable of solidifying them and transporting the containers with the solidified wastes, immediately to the place where they are finally deposited. The containers in or near the station are handled, and the binder is added, under a shield. A plant for carrying out the process incorporates containers, each with a cover in which is an agitator, an outlet for gases and an inlet for binder, a vent gas purificn. system and a unit for prepg. and adding the binder. The many costly and dangerous operations performed at present are no longer necessary. The risk to the environment is considerably reduced. Filling and binder addn. can be carried out so that no radioactive substances can escape from the containers. The vol. of integrated wastes resulting from the radioactive wastes and the binder is considerably reduced.

Title: Extensible elastically retractable pleating in flexible material - with stretched elastic tape fixed to material by adhesive tape
IPC: B65H45/30
Filed: 1976-05-10
Abstract: Extensible elastically retractable pleating in a support of flexible matl., e.g. woven or non-woven fabric, paper, synthetic sheets, etc., is formed by joining an elastic tape in the stretched state to the support by means of a wider adhesive tape. The adhesive tape extends beyond the elastic tape on both sides, enclosing it over the support. Release of the elastic tape after fixing causes contraction of the assembly to form the pleating. Method allows formation of pleats, partic. for protective garments, in simple effective conditions.

Title: Monolithically integrated semiconductor device - integrates bipolar pref. NPN transistor structure with others using gaps in at least one common transistor zone
Inventor: BERGER HORST
IPC: H01L27/07
Filed: 1976-06-24
Abstract: The semonconductor structure has at least two components having a common zone. A parasitic thyristor effect can be produced by a minority carrier injection current but is counteracted by means which prevent unwanted coupling between the components. A more highly doped zone is produced in the common zone (2) between transistor base (4) and the zone belonging to a further component. It represents the connection zone for the common zone (2), and forms a barrier (32) for the minority carrier injection current. This arrangement represses coupling interferences, esp. parasitic thyristor effects, while requiring fewer semiconductor surfaces than known solutions.
