Patent FR-2515472-A1 (FR)
Title: Magnetoresistive switch mechanism for telephone matrix key pads - has magnetically governed keys which alter conductivity of two adjacent conducting tracks at cross-point
Inventor: PETIT JULIEN
IPC: H03K17/972
Filed: 1981-10-27
Abstract: The keyboard button consists of a vertically-moving shaft (303) at the lower end of which is fixed a permanent magnet (311). An insulating bush (307) is inserted in the entry hole through the keyboard plate (201) which is made from a magnetic mateiral. When material. When the button is depressed a magnetic attractive restoring force returns it to its rest position. The magnetic plate also provides an electrical shield for the keys. A network of conducting magneto-resistive tracks (319) is deposited on the insulating substrate under the keys. The network is in the form of a series of parallel straight rows overlaid with a series of serpentine tracks which appro ch the straight rows to form short sections in which the two tracks are parallel, which thus create the 'cross-points'. When the magnet is adjacent to the substrate, the field of the magnet, which is concentrated due to its chamfer-grooved outline acts on the two parallel tracks simultaneously to locally increase their resistance. Insulated stand-off pillars (315,314) maintain the magnetic keyboard plate and the substrate correctly spaced apart.

Title: Portable electrically heated distn. plant - to supply domestic water etc., uses hot plate outside evaporator and has fan cooled condenser
Inventor: ISHIKAWA HIROKAZU
IPC: B01D3/02
Filed: 1981-11-09
Abstract: Portable, electrically heated, distn. plant mainly for the purifcn. of water is of the type which comprises a vertical cylindrical outer shell contg. a horizontal, electric hot plate in its lower end. A removable vertical cylindrical inner vessel rests on the hot plate and is located coaxially within the outer shell. A removable cover seals the top of the inner vessel. The cover is topped by an integral, hollow dome contg. a helical condenser coil. One end of the coil extends down into the top of the inner vessel while the other end projects out of the dome to deliver distillate. A condenser cooling fan is disposed coaxially within the cooling coil. Portable distn. plant is used for producing purified water for household requirements as well as cafe's, restaurants, offices etc. The heating element is not immersed in the evapn. vessel so scale does not accumulate on the element. The inner vessel can be lifted from the outer shell to facilitate cleaning. Fan-cooled condenser increases output.

Title: Regularly shaped flake ice prodn. - uses coaxial tubes alternately cooled and heated to release flakes
Inventor: GALIAN FRANCOIS
IPC: F25C1/12
Filed: 1981-12-14
Abstract: Process used a series of coaxial alternately filled with refrigerant to form the ice or by warm heat transfer fluid to detach the ice flakes. The tube surface upon which the ice forms is covered with a net, the mesh opening of which defines the shape of the ice flakes. Water is trickled down the annulus of the tubes forming an ice layer of thickness equal to the thickness of the net; a temp. of about 0 deg.C is used to facilitate the thawing of the flakes from the tube. When the flake has formed, the tubes are warmed from the bottom upwards causing the ice flakes to become detached and to fall down the annulus into a flowing stream of cold water. Used in prodn. of ice of regular particle size for use in the food and drinks industry and for mixing concrete and plasters in the building industry to compensate for the exothermic nature of the mixing process for certain compounds.

Title: Door-activated vehicle antitheft alarm - includes connection to hazard flasher circuit in addition to alarm device
IPC: B60R25/104
Filed: 1982-01-25
Abstract: The circuit for a vehicle includes a set of switches attached to each of the opening doors.

At the same time power is supplied to the hazard flasher light circuit, so that they may operate under the control of the flasher control unit. The additional circuitry may be added to the normal hazard flasher circuit without disruption of this circuit, by means of a pair of connecting terminals. The warning may be provided by simultaneously activating all four turn indicators and the courtesy light.

Title: Hot air dryer for pasta prods. e.g. macaroni and spaghetti - has progressive temp. rise lower deck with superimposed contra-flow cooling deck
Inventor: BARDET-NEYRIN RENE
IPC: A23L7/109
Filed: 1982-03-18
Abstract: Drying tunnel for pasta prods. in cut lengths, partic. maracron macaroni and spaghetti, is of the type in which lengths of the prod. are hung over rods of a horizontal conveyor which advances the rods through the tunnel. The tunnel contains fans which circulate air through heater batteries and then in contact with the conveyed prod. The tunnel is constructed as at least two superimposed drying decks. The temp. of the prod. is raised progressively via a number of stages in the lower deck to reach a maximum temp. at the outlet end of the lower deck. The prod. is transferred up to the corresp. end ot the upper deck where a conveyor returns the prod. through the upper deck space in reverse direction to the lower deck conveyor. The temp. of the prod. is lowered progressively via a number of stages in the upper deck. The temp. differences between superimposed stages of the lower and upper decks are kept as small as possible. Pref. a third, cooling conveyor deck is superimposed on top ot the second from which prod. is transferred by an elevating conveyor. The arrangement of superimposed decks reduces floor space requirement. Heat losses are reduced by having small temp. differentials between upper and lower decks. Condensation problems are greatly alleviated.

Patent FR-2530991-A1 (FR)
Inventor: COQUILLARD MICHEL
IPC: B23Q39/04
Filed: 1982-07-27
Abstract: A method of, and apparatus for automatically machining work pieces, wherein a plurality of single spindle units are fixedly attached to a support, and the work pieces are maneuvered in front of the work units by a translatable table. The number of single spindle work units is determined by the formula 2N-1, wherein N is the number of machining operations to be performed on each work piece. As such, there is an odd number of work units thereby creating a central unit which carrys out the last machining operation to be performed in the work piece. The axes of the work units are precisely equally spaced from one another, and this spacing equals the spacing between the work pieces. The apparatus is cyclically operated so that a plurality of work pieces can be worked on simultaneously by individual work units and a new work piece can be loaded when the machining operation is completed on a previously loaded work piece.
