IPC: B29C49/20
Filed: 1975-02-20
Abstract: Hollow bodies, e.g. aerosol containers, are produced from thermoplastic materials having a crystallisable structure, e.g. polyethylene terephthalate, by (a) making a preform from the material, (b) decreasing the diameter of the preform by an axial drawing operation, and (c) expanding the preform to such a degree, at at such a temp., that the expanded body is entirely in a biaxially oriented state, including the neck region. Gives moulded plastic bottles having accurate dimensions and a good mechanical strength over their entire body. Prodn. of rejects is decreased.

Title: Sewing thread bobbin mfg. - has band rolling unit integrated into winding machine to give a single-stage process
IPC: B65C5/02
Filed: 1975-03-13
Abstract: The process to manufacture finished band rolled bobbins of sewing thread, for use in sewing machines, has the band rolling unit as an integral part of the automatic bobbin winding machine with a conveyor located between them which on the one hand operates in sympathy with the transfer of the bobbins from the shadow spindles to the bobbin carriers and on the other hand operating with the intermittent action of carrying the bobbins during the winding time to the operating station of the band rolling unit, the bobbin carriers and the band rolling station being separated by the same interval as that between the shadow spindles. The system gives an integrated unit where the bobbins are finished without being carried to a separate machine, and where the end of the thread is held in place until secured.

Title: Light construction transverse support for rear axle - with flat strips welded into T or cross profile
IPC: B60G21/05
Filed: 1975-03-13
Abstract: The rear wheel are supported on trailing arms which are fitted to a transverse support, whose ends are mounted on the chassis by elastic bearings. In order to provide a light, yet strong transverse support, it is made up of flat metal strips.

IPC: C05F17/00
Filed: 1975-04-15
Abstract: Composting waste by contact with an oxygen-containing gas, which is known per se, is accelerated when the amount of oxygen which has been consumed in the oxidation reactions is replaced.

Title: Corrugated thermoplast sheet made by mechanical deforming
IPC: B29C51/22
Filed: 1975-05-09
Abstract: A method of continuously deforming a sheet or strip of thermoplastics, to give an undulating or corrugated sheet, consists of passing the seet between two opposite, moving rows of blocks possessing rows of combs or projections which mesh together and thus deform the sheet into an undulating pattern between them; the envelope around any projection overlaps that around an adjacent projection, the projections being non-linear, in partic. zigzag or sine-wave shaped. The basic principle is that the sheet is continuously advanced and deformed without being laterally clamped, the front along which the oposite sets of projections engage the sheet being a non-straight line. Used for mfg. all kinds of undulating or corrugated thermoplastics sheet which might otherwise be made, e.g., by vacuum for ming.

Patent FR-2326226-A1 (FR)
Title: High temp. reactor - uses radiant heat supplied to porous reactor tube
IPC: C01B31/30
Filed: 1975-10-03
Abstract: High temp. reactor e.g. for pyrolysis, decomposition and combustion reactions of organic and inorganic cpds. in which all the heat is supplied by radiation coupling comprises a reactor tube of porous refractory material capable of emitting radiant energy. Inert fluid is directed under press. through the porous tube wall to provide a protective blanket for the inside of the reactor tube. Reactants are directed in a predetermined path axially of the reactor tube and confined by the protective blanket within the central part of the tube. A heat shield directs radiant energy from an electric radiant energy source into the reactor tube to coincide with the path of the reactants. Since heat is supplied by radiation coupling the temp. of the reactant stream is independent of the temp. of the walls of the reactor tube. The tube therefore does not have to be made of material capable of withstanding the high temp. to which the reactant stream is subjected. The protective inert fluid blanket isolates the wall of the reactor tube from the reactant stream and prevents clogging by the accumulation of precipitates and deposits.

Title: Induction brazing of metals - using differential expansion of heated metal ring to apply radial pressure to joint surfaces
IPC: B23K13/00
Filed: 1976-04-13
Abstract: Metal workpieces (I) are welded using a filler or brazing material with m.pt. lower than (I) esp. the welding of large thin pieces where part of the joint is not flat. Welding is carried out using two pressure plates, >=1 contg. an induction heating coil, and an insulating plate. The improvement is that a metal element with suitable magnetic properties, and a different coefft. of expansion to (I), is placed round the parts of the joint which are not flat so the latter are heated by conduction from the element; the element is heated by induction and press. is exerted on the joint in a radial direction during welding. The metal element is pref. a ring with a lower coefft of expansion than (I) so that radial pressure is exerted on the joint while axial pressure is applied by a press. Induction and conduction heating are combined with pressure to make good joints.

Title: Pressure relief valve for aircraft engine compressor - has valve mounted on pressure dividing wall and operated by high mechanical advantage linkage
Inventor: CAMBOULIVES ANDRE ALPHONSE MED
IPC: F04D27/02
Filed: 1976-07-28
Abstract: The pressure relief valve (5) for interstage control in aeroengine compressors consists of a hemispherical casing (5b) with a flat diametral facing (5a) with a pressure communicating hole (10).
