Patent FR-2263867-A1 (FR)
Title: Cut-out machining method for pallet bases - uses milling machines to successively deepen cut-outs
IPC: B27C5/02
Filed: 1975-03-05
Abstract: A pallet making method includes a system of making a pair of cut-outs in each side member (2) which supports a set of boards (1) at right angles, these cut-outs being positioned to allow the blades (3) of the fork of a fork lift truck to slide underneath the pallet. These wooden side members are fed from a magazine onto a conveyor so that they are passed down a row of wood milling machines, so that after a shallow initial cut has been made, the cuts are made deeper by successive cutters. The milling tools are carried on swinging arms, so that the arm on each machine is swung further inwards that that of the preceding machine, ensuring a deeper cut.

Title: Folded cardboard box blank - uses flaps on one part which fit into slot on second part
IPC: B65D5/10
Filed: 1975-04-30
Abstract: A blank for a cardboard box has extension flaps (5, 6) on two opposite sides (1, 11). One of these flaps has tongues (91, 911) and the other has a slot (7) into which the tongues fit. The flap with the tongues can be divided into two parts (51, 511) with an interlocking part (13) formed at the split line. Each of the two parts of the split flap has two bend lines (10) set at angles to the side fold (11). The bend lines run from the ends of the side fold. Using these lines each part of the split flap can be inserted into the slot on the other flaps, one at a time. The tongues are thus trapped beneath the top of the box and held in place by the interlock.

Title: Mfr. of multilayer paper - uses layers wound together on large roll and plastics outer protection sealed at edges
IPC: B29C65/02
Filed: 1975-10-23
Abstract: The several layers of material (5,6,7,8) required to manufacture the product are each contained in a separate roll. These are gathered together forming a number of layers passed between calendering rollers. The outer layers (7,8) are plastic film, providing a protection for the inner layers, and a paper tape (11,11') is laid each side of the multilayer sheet as it is wound into a large roll. The ends of this are heated to seal the plastic layers together, permitting the roll to be stored without deterioration. When unrolling, the paper tape is removed, preventing the plastic layers sealing together as a mass.

Title: Water box junction for nuclear reactor steam generator - permits pump dismantling without draining water from heat exchanger
Inventor: LECOMTE ROBERT
IPC: F22B1/02
Filed: 1975-12-31
Abstract: A water box of the type forming a junction between, on the one hand, a steam generator arranged around a vertical axis, with, at its bottom end a tube plate limiting the cavity of the water box, together with a pump the vertical axis of which lies along the extension of the axis of the heat exchanger, below the box, and on the other hand, concentric inlet and outlet conduits for the pressurised cooling water of the nuclear reactor, is modified by the fitting of a nest of sleeves forming syphons. A first sleeve having the same axis as the pump forms a continuation of an opening in the bottom of the water box, and is open at the top for the passage of the pump shaft and its impeller. A second sleeve concentric with the first and enclosing it completely, is also open at the top, whilst a third sleeve, eccentric to the first two, is closed by a hemispherical top which is, in part welded to the second sleeve. The bottom free edge of the third sleeve thus forms with the second, a passage joining the interior of the second sleeve with the rest of the box. The second and third sleeves form a first syphon, and the first and second, a second syphon. Two arrangements of bulkheads connect the inlet duct from the reactor core to the inlet zone of the tube plate for the heat exchanger, and connect the outlet zone of the tube plate to the first syphon for the return of the cooling water through the syphons to the duct leading back to the core. Makes it easy to dismantle the pump on the water box without it being necessary to drain and store under awkward conditions the water in the steam generator which has been in contact with the fuel element assemblies.

Title: Plate-type heat exchanger module - has plates supported by skeleton of tubes through which water flows
Inventor: CLOCHEY LUCIEN
IPC: F28B1/06
Filed: 1976-01-13
Abstract: The heat exchanger module is for use between a liquid flowing inside a set of plates and gas with natural or forced circulation. It comprises a skeleton of tubular construction supporting the plates, the tubes acting as supply and discharge pipes for the water to be cooled. A cooling tower of the desired capacity is obtained by fitting the necessary number of modules together, it being merely necessary to couple the supply and discharge tubes up together. The modules may be used to construct a natural-draught cooling tower for a power station etc, and the supply to all plates can result in the same losses, i.e. there are the same number of elbows and T-pieces and the same pipe lengths.

Title: Heat exchanger connector for fast neutron reactor - gives better distribution of liq. and better thermal insulation
Inventor: BERNIOLLES JEAN-MARIE
IPC: G21C1/03
Filed: 1976-05-04
Abstract: After simple crushing, the rock sample is pyrolysed in an atmosphere of inert gas (pref. argon, helium or nitrogen) at 400-1000 degrees C; from the furnace, the pyrolysis prods. are carried on the same inert gas to a chromatographic appts., where their benzene content is measured. Thus the benzene content of the sample is determined in ppm; this is converted to wt.% of organic carbon by a linear relationship that has been experimentally established (and whose parameters depend on the particular temp. used for the pyrolysis). The appts. used has electromagnetic valves to control the flow of inert gas, and either an infra-red detector in the chromatographic appts., or one using flame ionisation.

Title: Purificn. of polluted effluent by deep tank aeration - using single pump to aerate, circulate and homogenise the liq.
Inventor: LEJEUNE PIERRE
IPC: C02F3/22
Filed: 1976-07-08
Abstract: Process and plant are for treatment of polluted effluent by aeration. Air is drawn into and dissolved in liq. pumped from a tank of the effluent and the oxygen enriched liq is returned to the effluent tank. The way in which the liq. is pumped from and returned to the tank produces a continuous circulation and agitation in the tank do that the effluent is homogenised and organic and mineral substances are held in suspension. The processing plant pref. comprises a deep tank with a vertical partition dividing it into two zones communicating at a gap between the tank bottom and the partition. A U-tube has its riser in one zone and its downpipe in the other, with its bend through the gap. A pump lifts liq. from the downpipe zone and pumps it down the down pipe air being entrained into the liq. via a branch to atmos between pump delivery and downpipe. The riser delivers oxygenated liq. into the second zone and simultaneously creates return circulation to the first zone. Low energy consumption is achieved by employing a single pump which is responsible for aeration, circulation and homogenisation.

Title: Cardiac stimulator monitoring appts. - has comparator for stimulation signal and reference frequency from quartz oscillator to actuate alarm
Inventor: STEMPLE GUNTER
IPC: A61N1/37
Filed: 1976-09-06
Abstract: The cardiac stimulator monitoring apparatus compares the frequency of a stimulation signal in a comparator unit with a reference frequency produced by a quartz oscillator. An alarm is given by an indicator when the two differ by more than a predetermined amount. The stimulation signal can be detected inductively or galvanically, and transformed into a monitoring impulse. The reference frequency can be determined by the position of a numerical counter connected to the quartz oscillator, and reset to zero by the monitoring impulse.

Title: Suspension legs for washing machines - involving thrust sensitive damping and simplified couplings
Inventor: MILLY LUCIEN
IPC: D06F37/20
Filed: 1976-12-20
Abstract: Suspension units for washing machine bodies incorporate a combination of a spring-damped plunger and tubes lined with conic ended sleeves which dilate proportionally to thrust on the plunger, thus providing a proportional increase in damping friction. Compared with units described in FR1289955, simplified forms of spherical bearing support the base of the unit. The ends of the units are linked by pin and sleeve couplings. An alternative coupling involves a squat tubular rubber bearing incorporating a spring to restore axial alignment after deformation in torsion or shear. The units are light and simple and provide good damping of vibration and noise.
