Title: Avoiding carbon deposits during annealing, from lubricants - in the bore of drawn copper tubes, by sweeping with nitrogen
Inventor: DINER OLIVIER
IPC: C22F1/08
Filed: 1975-04-25
Abstract: New treatment process for tubes, made in copper or its alloys, after drawing in the presence of a lubricant, the treatment being designed to eliminate the formation of carbon deposits adhering to the bore of the tubes due to decompsn. of the lubricant during the annealing treatment. The novelty is that the tube is heated to a temp. providing an adequate vapour pressure from the lubricant and a gas is fed through the tube t remove the vapour. The flow of gas is pref. employed during the entire annealing cycle, using a weak reducing gas or an inert gas, esp. N2, CO2, steam or their mixt. to obtain a residual carbon deposit of max. 0.5 mg/dm2 and generally below 0.15 mg/dm2 in the bore. Process is useful for example, in domestic sanitary piping where pitting corrosion is promoted by carbon deposits, or in other applications.

Patent FR-2307518-A1 (FR)
IPC: A61F13/06
Filed: 1976-04-14
Abstract: A single piece of high-tensile elastic adhesive tape which is die-cut in a particular manner so as to form a supportive device that is capable of limiting joint movement. The device comprises a sheet of a conformable, high-tensile, elastic, permanently tacky, pressure-sensitive adhesive tape material that has widthwise stretch but no lengthwise stretch, and is covered, on the adhesive portion thereof, with a sheet of release paper of the same size and shape. The device structure is such as to have a pair of flanging anchor wings on either end of an elongated piece of the adhesive material, and having a pair of angularly set anchor tabs positioned between the pairs of anchor wings. While the device can be stretched across its width at any point thereon, there is no stretch or dead stretch along the length thereof. This attribute serves as a basis for limiting specific joint movement. For example, when it is applied with the intention of limiting ankle inversion, one pair of anchor wings is adhesively secured to the inside of the ankle, just below the ankle bone, while the rest of the device is brought under the foot and up along the outside portion of the ankle and leg. The thusly positioned device is further secured thereto by means of the anchor tabs which encircle the ankle joint, adhesively overlapping the outer edges of the first pair of anchor wings, and the second pair of anchor wings then are adhesively attached to the outer portion of the calf. In this manner, the device limits ankle inversion because it has no stretch along the length thereof, while providing comfort and conformability for the ankle because of the elasticity of the device across its width. Furthermore, because of the predetermined die-cut structure of the device, it permits those persons not specially trained in the traditional techniques of supportive joint strapping to effectively apply and use same. The device also saves labor and time for the skilled athletic trainer when used alone or in conjunction with traditional strapping techniques.

Title: Prodn. of model for forming hollow moulds - by coating model with thin silicon layer, thick layer of silicon and HF sensitive material and filling with silicon and aluminium
IPC: B29C33/38
Filed: 1976-11-25
Abstract: Cavity moulds for compression moulding plastics materials fused by high frequency (HF) dielectric loss heating are made by coating a pattern a) with a thin (0.4-0.7 mm thick) layer of silicone resin deposited from solution (by e.g. spraying), covered with b) a thicker (1-3mm) layer of silicone resin extended with a material (such as polyvinyl acetate, PVC or epoxy resin) having a higher HF loss factor. The second coating compsns should be non-melting up to 200 degrees C. The bulk of the mould body is then cast using a conventional silicone resin/aluminium powder blend. Used esp. for moulds for shaping thin layers (1mm) of material such as flexible PVC coatings on supports for shoe uppers or other artificial leather work. Complementary heat generation at the cavity surface reduces mould cycle times, esp. when gelling thin layers of material relatively susceptible to heat loss to moulds or mould coatings not warmed up by the HF heating. Alternatively allows larger (>1200 cm2) mouldings to be formed using conventionally sized 15-20 kVA generators.
