IPC: C04B7/44
Filed: 1998-04-30
Abstract: The invention is related to a method and an apparatus for producing cement clinker, in which the cement clinker is first of all burnt in a burning zone and then cooled in a cooling zone, wherein the cooling takes place at least partially by the delivery of fuel and steam, characterised in that in a first cooling phase the delivered fuel is mixed with the cement clinker and initially pyrolysed and the resulting pyrolysis products have a strong endothermic reaction with the steam, so that the cement clinker is quenched in such a way that at least 95 percent, preferably all, of the liquid phase contained therein is transformed into glass.

Title: Electron beam tube arrangement - is for vertical deflection response control in industrial TV or electron microscope systems
IPC: H04N3/00
Filed: 1974-08-20
Abstract: The system relates to the vertical scan deflection of electron beam tubes of the type used in industrial visual display units and electron microscopes. The waveform of the time base function using a triangular waveform with uniform discrete steps is modified by the superimposition of a ripple function involving two small steps each of which is shorter in time than the basic stop, so that the beam vertical voltage deflection control reverses the scan deflection a small step before continuing with the main trend. This is achieved by two separate voltage generators operating in synchronism.

Title: Oxidising sulphur cpds with oxygen-contg gas - in presence of mixed phthalocyanine catalyst to minimise over oxidation
IPC: C10G27/10
Filed: 1976-08-09
Abstract: A sulphur-contg. cpd. is oxidised with an oxygen-contg. gas in a medium having a pH of 8-14 in the presence of a mixed catalyst comprising phthalocyanines of Groups VIIB and VIII metals in a mol. ratio of 1:1 to 1:6, the oxidised sulphur compound being subsequently recovered.

The process is used to eliminate mercaptans and hydrogen sulphide for reasons of environmental pollution. The particular catalyst system used minimises over-oxidation with its consequent problem of colour generation in the treatment of petroleum charge stock.

Title: Fabricating thermoplastic layflat film - in two layers oriented at right angles
IPC: B29C48/21
Filed: 1980-04-25
Abstract: In a process for fabricating a laminated cylindrical film with a plastic resin base, the laminated structure consists of three layers, the inner layer being stretch oriented transversely and the outer layer being stretch oriented longitudinally. The median layer is formed from a film having a lower fusion point than the inner and outer layers, and consolidation is brought about by heating to a temp. slightly below the fusion point of the median layer so that it is bonded to the other two layers. The three layers may be extruded from annular concentric orifices, and orientation in perpendicular directions gives greater strength and enables thinner films to be used for a given weight. The three films are extruded from concentric orifices. The outer layer is then stretched longitudinally between two sets of rolls while the inner film is expanded by a rotating mandrel, the film being then cooled rapidly and flattened. The outer and inner layers may be of a high m.pt. polyolefin while the median film may be of e.g. ethylene/vinyl acetate or ethylene/acrylonitrile copolymers.
