Patent FR-2634876-A1 (FR)
Title: Formed explosive charge
Inventor: GLINIASTY MICHEL DE
IPC: F42B1/02
Filed: 1980-06-13
Abstract: The present invention relates to a formed charge of the type comprising a priming system and a main explosive charge surrounding a metal covering for projecting it in the form of a piercing jet. It is characterised in that it comprises, between the priming system and the main explosive charge, a detonation-wave generator capable of generating, at least in the part of the charge adjacent to the covering, a detonation wave approximately parallel to the surface of the covering. As regards a hollow charge having an opening angle in the region of 60 DEG , a priming system 3 primes an explosive layer 11 which raises a metal plate 10 against a metal plate 10a at a raising angle of approximately 9 DEG about a circular screen 9. A conical wave is thus produced in the explosive charge 12 and is parallel to the covering 1.

Title: Ladies undergarments - made from elasticated fabric and hemmed with strips of the same material
Inventor: CLEMENT ARTHUR PAUL
IPC: A41B9/14
Filed: 1981-01-28
Abstract: Ladies' undergarments, such as knickers, normally supported by elastic ribbon or tape inserted at the welt or hem, are produced from a fabric having its own intrinsic elasticity, and hemmed with a strip of the same material, which is folded over the edges and sewn. Such hems are much thinner than those containing elastic tape, and are not so easily visible through outer clothing. They are also more comfortable to wear, and do not cause skin irritation. They dry more quickly after washing than the known garment, due to the absence of rubberised tape.

Title: Appts. purifying waste water by aeration and agitation - employs reaction propulsion to rotate aeration system and suction to extract sludge
IPC: B01F3/04
Filed: 1981-02-12
Abstract: A plant installation for the purificn. of waste water by simultaneous aeration and agitation, provision being made for pumped extn. or sludge from the base of the treatment vessel. The vessel contains a vertical, freely rotatable riser pipe. Near the lower end of the riser pipe, two symmetrically opposed, radial, perforated suction pipes are joined into the riser pipe. Above the level of liq. in the vessel, two symmetrically deposed, radial discharge pipes are joined into the rise pipe. The common axis of discharge pipes is at right angles to the common axis of the suction pipes. Pref. the riser pipe is rotatable between a foot step rearing in the base of the vessel and a steady bearing fixed centrally on the underside of the vessel cover. The footstip bearing is pref. pierced to allow settled sludge to be sucked up the riser pipe by a tube passed down the riser through the steady bearing. The discharge pipes are formed to rotate the riser pipe etc. by reaction propulsion as fluid is discharged. The installation is for aerating and agitating waste water and for periodically pumping out excess sludge. The design is simple and inexpensive. All motive power can be provided by a simple air pump.

Title: Mould cap for avoiding shrinkage pipe in cast ingot - has radiation-intercepting diaphragm and infrared reflector for returning emitted radiation
Inventor: BERG CHARLES ADOLPH
IPC: B22D7/10
Filed: 1981-06-15
Abstract: A cap for an open top mould includes a diaphragm for intercepting radiation emitted from the top surface of the liq. metal in the mould and to re-emit radiation back to the surface. A reflector or series of baffles return radiation emitted from the top of the diaphragm. Used as ingot casting. The formation of shrinkage pipe is inhibited in the casting of large metal parts. Metal yield is improved by reducing oxidn. and other chemical effects which occur on exposure of metal to the atmos. during casting and solidification. A roughing vacuum can be created within the mould structure to eliminate convective heat losses from the top of the ingots. The regions adjacent the top of the ingot may be heated with electrodes.

Title: Equipment to assist flow of heavy fuel oil - uses pipe with lining permitting osmosis between liquids on each side
Inventor: BAUMGARTNER PIERRE
IPC: F17D1/12
Filed: 1981-08-21
Abstract: The method of assisting flow of a liquid such as heavy fuel oil (6) through a pipe (4) uses an inner lining (5) of a material which assists the flow. Between the lining and the pipe is a layer (7) of fresh water, and salt water is also allowd to flow through the inner lining. The lining is made of a material which allows osmosis to operate between the fresh and salt water, assisting the flow. To assist the flow under these conditions, a tank containing oil mounted a certain distance above a vessel to receive the oil is connected by a pipe with a vertical and a horizontal section. Upper and lower connections allow the fresh water to flow between the pipe and lining.

Title: Magnetic traction enhancement for railed vehicles - uses electrically excited coils mounted round axles to establish magnetic flux through rails and returning through next axle
IPC: B61C15/04
Filed: 1982-01-12
Abstract: The traction of a rail vehicle during both starting and braking is improved by magnetic action on the rails. Coils are mounted on the axles of the vehicle and are energised electrically to generate a magnetic flux traversing the axle, the rails, and the other axle of the bogie, creating magnetic attraction between the wheels and the rails, and inducing eddy currents in the rails which help dissipate the kinetic energy of the vehicle during braking. The coils are mounted on the bogie so they enclose the axis of the axle, with sufficient clearance provided to accommodate the movement of the axle in the suspension of the bogie.

Title: Homogeneous thermal treatment of materials by microwaves - transmitted by pairs of aerials penetrating the waveguides
Inventor: JACOMINO JEAN-MARIE
IPC: H05B6/72
Filed: 1982-01-20
Abstract: Appts. for the thermal treatment of material by microwaves consists of an ultra-high frequency generator delivering its energy to the inside of a rectangular metal wave guide with a short-circuit plate at each end. One or more pairs of adjustable aerials traverse one face of the guide to transmit the energy from the interior of the guide in the direction of the material to be irradiated. The electromagnetic energy profile radiated from the guide can be tailored to the dielectric properties of the material being treated and its distribution within the treatment chamber. The treatment field is homogeneous. Energy transfer to the material is good because of the electric field parallel to the largest dimension of the material. There are not dangerous interactions between the emissions of different guides.
