Patent FR-2281631-A1 (FR)
Title: Nuclear reactor fuel assembly - with elements spaced by helical fins arranged to reduce coolant flow around outer elements
IPC: G21C3/338
Filed: 1974-08-08
Abstract: A nuclear fuel sub-assembly comprises a bundle of elements in a hexagonal wrapper. The elements are spaced apart and from the wrapper by helically wound fins of uniform radial height. Fins on an outer row of elements are wound at half the pitch of those on inner elements, and alternate outer elements are wound opposite hand. Outer and intermediate elements are oriented so as to nest together. The arrangement is for use in a sodium-cooled fast reactor. The half pitch windings provide more lateral support points for the outer elements, and the increased flow resistance reduces over-cooling of the outer elements.

Title: Determining salt time for meat - using scale which indicates time required as a function of meat thickness
IPC: A23B4/02
Filed: 1974-11-28
Abstract: Thickness measuring device for determining the salting time required for the treatment of meat comprises a platform with an upright which supports a fixed plate provided with graduations; the comparison plate, which can move vertically in a parallel plane, is carried by a parallelogram which is articulated to the upright and operates the pointer. A return spring enables the comparison plate to go back to its initial high position. The time required for the salting process is a function of the thickness of the meat. In use the comparison plate is lowered on the meat placed on the platform, the needle then gives a reading on the scale showing the salting time needed.

Title: Electronic controller for windscreen wiper - can change frequency of swing time of dwell, and operation or windscreen washer
IPC: B60S1/48
Filed: 1975-02-06
Abstract: The electronic system can be used to control the frequency of operation of any type of vehicle windscreen wiper, the frequency being dependent on such conditions as rain, drizzle, etc., and the line of dwell between swings can be extended as required, by the use of a timing device. A visual reminder can be incorporated for the driver, and it can be switched in and out by the operation of the ignition key. The device can operate to give two swings after each dwell period, and can be combined with the operation of the windscreen washer, which can be automatically started after a wiper cycle. All operations can be controlled by a single control unit.

Title: Recovering energy from boiler installations - by washing combustion gases, transferring heat from wash liquor, producing hot water
Inventor: DENIS LOUIS HENRI DANIEL
IPC: F23J15/04
Filed: 1975-09-19
Abstract: A method of recovering energy, partic. from boiler installations using solid, liq. or gaseous fuel, consists of putting in the combustion gas circuit an appts. for purifying the gas by washing it with liq. e.g. water in the form of an atomised spray, and transferring the heat from the wash water to a fluid in a heat exchanger. Before the gases enter this appts. they pass through an appts. for removing dust from them, of known type e.g. mechanical, centrifugal, electrostatic. The invention brings about the suppression of thermal and chemical pollution of the atmos. and increases the yield of energy from 30-35%, obtd. in existing installations, to 95-98%. The investments cost can be recovered in a short period, 1 to 6 months, by the economy in energy achieved.

Title: Electric motor including permanent magnets - uses rare earth stator super magnets to effect polarity inversion in rotor
IPC: H02K53/00
Filed: 1976-02-06
Abstract: Electric motor based on the use of small permanent magnets in the rotor and stator assemblies replacing the normal windings set in longitudinal slots. Repulsion of the rotor is normally achieved by polarity inversion caused by short period currents in the associated rotor windings. The design is intended to overcome the power loss in external supply circuits. Each rotor bar magnet has an associated rare-earth super magnet in the form of a shallow 'U' such that the bar magnets move through the hollow of the 'U' as their supporting soft iron disc rotates. Polarity inversion is achieved by the proximity of the high field stator magnets.

Title: Antitheft sound alarm system with neutralising circuit - uses pushbutton keys to control excitation of relays for neutralising alarm
IPC: G08B29/08
Filed: 1976-04-09
Abstract: The round alarm uptem has an alarm whose the electrical supply is controlled by a relay. This relay is energised via a normally open circuit. This circuit is closed by any one of a number of detectors. A timing circuit delays the actuation of the round alarm when a detector is triggered. This delay enables the legitimate user of the uptem to neutralise it by interrupting the supply to the alarm. Neutralisation is achieved by pressing out a predetermined combination of a keyboard (T1-T6) certain of the hep are classed as active and are contractors which are connected in series into a relay circuit. The last hey (T6) in the combination controls a relay (L3) whose contact interrupts the supply circuit to the round alarm.
