Patent FR-2488151-A1 (FR)
Title: Electrostatic diffuser for mixing paint powder - has refrigerated air passing ionising electrode and mixing with air-paint mixture to avoid direct contact between paint and electrode
Inventor: VOLTAREL DANIEL
IPC: B05B5/16
Filed: 1980-08-06
Abstract: The mixer includes a central electrode shaped as a plain pointed needle. This electrode is surrounded by a second ring electrode. The ionisation zone lies at the end of the inner electrode around its point inside the ring. The central needle electrode is surrounded by a ring which is spaced from the needle to define a channel between them. Compressed air flows through this channel in order to refrigerate the central electrode. The air circulating around the electrode becomes charged with the same polarity as that of the paint powder. Powder is introduced through an annular opening surrounding the cylinder and carried by a flow of air up to join the refrigerating air passing the electrodes. The air/powder mixture passes the electrodes at high speed and mixes with the ionised refrigerated air. The powder does not come into direct contact with the electrodes, and thus does not encrust it.

Title: Sanding accessory for power drill - uses rigid round head plate fixed pivotably to spindle end by elastic conical node block
IPC: B24D7/16
Filed: 1980-10-01
Abstract: The sanding accessory (1) attaches to a portable drill, and comprises a rigid circular plate (10) connected to a drive spindle (12). The connection permits articulation i.e. allows the angle between the spindle (12) and the plate to vary whilst the longitudinal spindle axis passes approximately through the centre (10x) of the working face (10a) of the plate. The arrangement permits the working face to follow a plane work face under nominal spindle (12) inclinations from the normal, and the plate can receive disposable abrasive sheets (11). The connection incorporates a conical part (13) with an axial hole (14), the base (13a) fixing to the plate and the hole locating the leading spindle end (12a) clear of the plate.

Title: Temporary fixed connection of wheel to shaft - uses radial shaft expansion in pulley bore using conical hydraulic piston in thin-walled sleeve
Inventor: BRU DANIEL
IPC: F16D1/091
Filed: 1980-10-14
Abstract: The rigid coupling may secure a pulley wheel (4) on a shaft (3), using the axial displacement of a conical piston (8) in a sleeve (5) of the complementary form to effect a radial expansion of the shaft once located in a pulley (4) bore. The conical interface (6) is lubricated and the displacement of the piston relative to the sleeve is brought about by hydraulic force. The piston and the sleeve are mounted in a hollowed out (2) portion of the shaft, and the former may have radial (8a) and axial (17,18,22) passages feeding fluid under pressure to circumferential grooves (15,16) and the conical interface. A circular length (7) of the sleeve bore may locate opposite a reduced circular length (9) of the piston to form a pressure chamber. The chamber may be sealed (14) and closed (11) by a composite ring which screws (12) into the sleeve.

Title: Control system for pneumatic tube communication network - uses microprocessors at each station in master-slave communication with common control unit to operate valves to route tubes
IPC: G06Q10/00
Filed: 1981-06-30
Abstract: A number of pneumatic tubes link input and output stations between which information is carried in a cartridge propelled by air under pressure from blowers. A microprocessor assembly is located at each station to communicate along a coaxial cable to microprocessors at other stations connected in parallel to the cable. A microprocessor in a common control cabinet provides centralised control through the microprocessors using a programmable communications interface connecting a memory to the line driver and receive circuits. Input and output expansion circuits connected to a power interface provide control for the indicater lamps and blower meters and permit reception of monitor signals. The interface ensures that the respective control valves along the tubes are operated to route the cartridges to the correct stations.

Title: Automatic peritoneal dialysis bag drainage control during treatment - using modules, each having corresponding clamp and hook arrangement, and UV sterilisation system
Inventor: FOURNIER DOMINIQUE
IPC: A61M1/16
Filed: 1981-11-06
Abstract: The appts. consists of three modules. The first module, situated above the other two, permits gravity feeding of the dialysis liq. and contains retractable hooks for supporting dialysis liq. bags. The weight of a filled bag causes the hooks to drop and break an associated electrical contact. At the end of phase after a first bag is introduced, the hook is upwardly spring biassed. If the bag is not yet empty, an alarm is triggered. The second module has a set of clamps (4), equivalent to the number of hooks, whose rate of opening is controlled by a microprocessor. The opening of a clamp causes the associated bag to be drained into the peritoneal cavity of the patient. The third module comprises a thermostatic heater, a w source, and a single clamp.

Title: Floor standing pendulum clock of triangular construction - allows corner placement and up to three different clock faces or other panels in kit form
Inventor: ODOBEZ GUY
IPC: G04B47/02
Filed: 1982-01-15
Abstract: The clock has a triangular construction which allows it to be placed in the corner of a room.

Panels other than a clock face may be used such as bookcases. Another possible realisation is a hexagonal clock with six base elements. The clock allows commercialisation in kit form. The clock may have just one movement, or one for each face.
Patent FR-2500718-A1 (FR)
IPC: A01F29/00
Filed: 1982-01-22
Abstract: The comminution machine with rotating container for comminuting cattle feed, such as for example hay, cereals, maize and straw, has a rotatable container on a floor which is inclined in a stationary fashion at an acute angle with respect to the horizontal, the container and the floor being pivotably attached to a frame as one unit, in which case they are suitable for being swivelled as a unit through 90 DEG  out of the horizontal and into the vertical. The container is thus used for loading fibrous material. The unit is swivelled back into the horizontal into the comminution position. The comminution takes place by an improved rotor-chopper-blower combination in the inclined floor which is suitable for cutting and blowing out the fibrous material in that the material spreads over the rotor during the rotation of the container. This container rotation brings about a lifting and lowering of the material, in which case the material is loosened by the inclined floor and intermeshing is prevented. The rotor has a multiplicity of improved, rotating thresher blades provided with end-mounted knives and constructed with broad sides, each blade having ends bent over in the rotational direction. The rotor is suitable for producing an air stream by means of which a separate conveyor for ejecting the chopped material is superfluous.

Title: Article with marble appearance - prepd. from synthetic resin, e.g. polyester, filler and mineral powder
Inventor: SEVI ROBERT
IPC: C04B26/02
Filed: 1982-02-04
Abstract: An article is claimed made of a material simulating minerals such as marble and comprising a mixt. of synthetic resin, a filler and a mineral powder. The novel feature is that the compsn. and the granulometric structure of the material are uniform throughout the entire bulk of the article, whatever the number, the colour and arrangement of the veins, marble effects and other aspect irregularities, these resulting only from the colouration difference of the resin distributed in the inter-granular voids. Also claimed is a process for prepg. the article. The articles have the appearance of natural minerals, partic. marble, while having exceptional mechanical and chemical resistances.

Title: Vented breeze block for building - has vertical air ducts close to one surface with odd number to compensate for offsetting
IPC: E04C2/52
Filed: 1982-02-04
Abstract: The block has ducts which form an air layer (3) between the main body of the block (1) and an outer block skin (4). The connections (5) between the skin and the body are sized and shaped for minimum area, compatible with rigidity and to give turbulence to upward air movement. The number of ducts is uneven, to give duct continuity with normal building course offsetting. The connections widen upwards, do not extend on one part of the block height, and resist shear forces due to weight and differential expansion.
