Title: Cementation process for forming a refractory metal carbide layer - on a (metal) substrate using a volatile halide of the metal to increase its diffusion rate
Inventor: VANDENBULCKE LIONEL
IPC: C23C10/36
Filed: 1975-03-21
Abstract: Method of forming a refractory metal carbide coating on a material contg. >=0.5% C comprises cementation in H2 at atmospheric pressure at 850-1250 degrees C. The article is coated with a powdered mixt. of the metal and its halide. The halide transports the metal to the surface and reacts with the carbon in the surface. The coating metal is Ti, Zn, Hf, Nb or Ta, while the substrate contg. the carbon may be carbon, graphite, carbides of W, M, Cr, the alloy Co/WC, cast iron or a steel. Such coated metals may be used in corrosion resistant vessels for chemical reactions, for cutting tools and for high temperature use. The coating is more firmly attached to the surface than in prior art, the coating is continuous and uniform. This is because during the diffusion, the metal as halide diffuses to the surface faster than the carbon, and can hence penetrate into the surface to some extent before reacting with the carbon.

Title: Electroformed thick-walled perforated sleeve - with mould release aided by inducing internal stresses
IPC: C25D1/20
Filed: 1976-09-01
Abstract: A thick-walled perforated cylindrical sleeve is mfd. by electrodeposition. A die is sensitised by deposition of a photosensitive layer and a pattern is copied on to this resin which is subsequently developed. Electrodeposition is then carried out. The contour and the density of the pattern points, the thickness and the treatment of the photosensitive resin, and the deposition conditions are studied as a function of the desired thickness without significantly deforming the pattern points and hence the perforations. The mould is removed using internal stresses b uilt up in the deposited metal, these stresses being controlled throughout the deposition in a range with a maximum at which peeling occurs during deposition and with a minimum at which removal from the mould is not possible without plastic defomation taking place and deterioration of the sleeve. The roll or sleeve can be used to impart a relief or cover with a protective varnish a design previously printed in several colours.

Title: Sepg. magnetisable particles from suspension - by draining suspension at predetermined rate from sepn. chamber contg. magnetisable material
IPC: B03C1/025
Filed: 1977-04-29
Abstract: Sepn. chamber contg. a mass of magnetisable material permeable to the fluid is filled with the fluid contg. the magnetisable particles. The fluid is then drained from the mass of magnetisable material. During this stage, a magnetic field is maintained in the mass of magnetisable material during a finite period after the filling and before the draining, and during the draining, such that the particles are magnetised and held in the mass of magnetisable materila. Finally, the magnetisable particles are extracted from the magnetisable material. Pref. a chain of sepn. chambers is used. they are caused to pass continuously through a sepn. zone in which a magnetic field is established. A high sepn. efficiency is achieved with a magnetic field of relatively low intensity. The time during which the fluid is maintained in the field before draining starts can be very short, usually 1 minute. Turbulence of the fluid within the magnetisable material is reduced to a min. The fluid can be withdrawn in a partic. uniform and controlled manner. The process is partic. useful for sepg. very small particles having a very low coefft. of magnetisation, e.g. paramagnetic particles. of impurities in kaolinite type materials.
