Title: Embrittling weapon casing to cause splinter formation on detonation - by subjecting to local heating to form narrow bands of martensite
Inventor: FRAYSSAC JACQUES
IPC: C21D1/18
Filed: 1978-10-13
Abstract: The appts. uses local heating to form narrow bands of martensite, esp. heating via a laser beam or an electron beam in vacuo. The laser or electron beam is pref. used to produce a rectangular pattern of zones of weakness extending through half the thickness of the metal and used for the propagation of a detonation wave. In one pref. appts., the grenade or shell casing etc. is rotated on its longitudinal axis so an electron beam can form peripheral zones of weakness; the beam is then moved along the casing with stepwise rotation of the latter so a grid of weak zones is obtd.

Title: Lifting concrete drum contg. radioactive wastes - by skirt fitting over drum, with lifting trunnions and slots engaging in spindles in blind holes in drum
IPC: B66C1/62
Filed: 1979-04-26
Abstract: A fixation device for lifting a cylindrical concrete drum contg. radioactive wastes and having blind radial holes distributed angularly over its periphery is composed of spindles of length slightly greater than the depth of the blind holes, each engaged in one of the holes, and a circular skirt. The circular skirt fits over the concrete drum and incorporates slots for fixing it on the spindles. It includes also two radial trunnions at 180 deg. one from the other, shoulder at their end, allowing lifting of the concrete drum by a bar provided with two arms and ended by a hook. The invention avoids the inconveniences of the existing device comprising three chains terminated by pins put into the holes manually with risk of exposure to radioactivity. The device according to the invention can be applied to all models of concrete drums with radial holes on their periphery. It allows lifting without any manual intervention. All the operations are effected remotely so that the operator is not exposed to harmful radioactivity.

Title: Low viscosity, high solids pressure-sensitive recording compsn. - contg. polymer latex partly replacing carboxymethyl cellulose
Inventor: LANGLAIS GEORGE OLIVER
IPC: B41M5/132
Filed: 1979-07-20
Abstract: A pressure sensitive copying material is produced by dispensing a chromogenic material in an aq. carboxymethyl-cellulose soln., adding Al nitrate to the soln. with stirring to cause pptn. of the CMC with entrainment of the oily soln., applying the resulting soln. on an intermediate sheet or support to form a coating which is then dried. The novel feature comprises replacing part of the CMC bya film-forming polymer latex, so that the dispersion has an increased solids content, but has after dilution for use ia viscosity less than 600 cps. and dries quicker on the sheet or support. Faster drying rate results in increased productivity.

Title: Increasing width of cast slabs during continuous casting - by inserting profiled consumable narrow walls in top of mould
Inventor: PIETRYKA JOSEPH
IPC: B22D11/05
Filed: 1980-02-21
Abstract: Slab is cast in a mould forming a rectangular cavity with at least one adjustable narrow mould wall. On top of the narrow mould wall is a pivot shaft for an elbow lever. The outer end of the lever is attached to the piston rod of a work cylinder, whereas the inner end of the lever is provided with a slot receiving a peg on a consumable mould wall, which is slightly narrow than the permanent narrow mould wall. To increase the width of the slab without interrupting the casting process, one or both narrow mould walls are moved rapidly outwards, so that one or two consumable narrow walls can be located in the mould cavity. The consumable walls become anchored in the solidifying metal, and travel downwards out of the mould with the slab. There is only a very short transition zone at the junction between the two different slab widths.
Patent FR-2450313-A1 (FR)
IPC: E04B2/74
Filed: 1980-02-29
Abstract: Free-standing walls (16) are fixed on a vertical post (1), it being possible to adjust the position of said walls with respect to the post (1) over a relatively large angular range. The post (1) comprises a supporting tube (2) and casing pieces (4) which are arranged concentrically therewith, are spaced apart from one another and are fixed on the supporting tube (2). Annular-gap segments (19, 20) are thus formed between the casing pieces (4) and the supporting tube (2). Each free-standing wall (16) is fitted with at least two hook-shaped anchoring parts which engage into the angular-gap segments (19, 20). The free-standing walls (16) have, with respect to the vertical post (1), a large adjusting range which is fixed by the annular-gap segments (19, 20). Narrow manufacturing tolerances do not have to be adhered to when assembling the parts forming the post (1). The vertical post (1) with the free-standing walls (16) mounted thereon is used for constructing exhibition stands.

Title: Rear wheel structure for electric vehicle - includes two deep wells on either side of floor of body housing sets of accumulators
Inventor: FROUMAJOU ARMAND
IPC: H01M50/249
Filed: 1980-04-02
Abstract: The rear wheel and axle structure for an electric vehicle includes wheels (1) attached to respective half axles (3). The axles are attached via the suspension to the body of the vehicle. The floor of the vehicle drops below the level of the axle, so that on either side of a central tunnel (5) there are similar wells (6). The central tunnel provides some support for the inner ends of the half axles. The two wells provide a secure housing for the accumulators which provide the power to electric motors driving the vehicle. In view of their considerable weight the secure low position is a suitable location for the accumulators avoiding bringing the batteries near to the occupants of the vehicle.
