Abstract: Chromium carbide powder and/or powder of an easily sulfidable metal are added to powdered crude metallic chromium to form a mixture thereof, which is then heated in vacuum to remove S, N and O by degassing so that consequently the crude metallic chromium is free from impurities to a possible maximum extent. Alternatively, powdered crude metallic chromium is heated in an atmosphere of inert gas to temperature between 800 and 1,400 DEG C and then an easily sulfidable metal is added thereto to form a mixture thereof. Subsequently, the mixture is, directly or after adding carbon or chromium carbide, heated again in vacuum or in an atmosphere of inert gas to eliminate S, N and O by degassing so that the crude metallic chromium is free from impurities to a possible maximum extent. Still alternatively, powdered crude metallic chromium is washed with inorganic acid such as hydrochloric acid, sulfuric acid or nitric acid or organic acid such as acetic acid to remove metal impurities such as Fe. The washed crude metallic chromium is then mixed with carbon or chromium carbide and the mixture is heated in vacuum or in an atmosphere of inert gas to eliminate S, N and O by degassing and consequently produce high-purity metallic chromium.

Abstract: An osteal prosthetic component of a prosthetic joint and a method of implanting an osteal prosthetic component in the medullary canal of a bone are disclosed. The osteal prosthetic component includes a stem for disposition within a medullary canal of a bone and a fluted wedge portion extending from the stem. The fluted wedge has wedge portions which define at least one flute between the wedge portions. An interference fit is formed between the wedge portions and the bone during implantation of the stem into the medullary canal. Movement of the osteal prosthetic component relative to the bone is thereby sufficiently limited to allow tissue growth into a tissue-ingrowth portion at the surface of the stem to substantially prevent micromotion of the stem relative to the bone.

Abstract: The invention relates to a method for colouring thermoplastic synthetic materials on the basis of polyolefin homo- or copolymers, wherein at least one pigment from the isoindolin class is blended with the synthetic material and wherein an acidic reacting additive, which is a stronger acid than the pigment, is added to the synthetic material in such a manner that substances which react alkaline with respect to the pigment and which are possibly present in the synthetic material are converted into their acidic form. It was found that due to the addition of the acidic reacting additive, the isoindolin pigment will no longer discolour in the synthetic material. Preferably, a colour concentrate is previously prepared by melting a restricted amount of thermoplastic synthetic material together with the pigment and the acidic reacting additive.

Abstract: The present invention relates to a bi-metallic clamping system for holding a heater firmly on the external surface of a hot runner nozzle body. The band heater-clamp arrangement of the present invention is formed by a cylindrical sheath (42, 44) which houses the heater coil (36). The sheath has an inner sleeve (42) formed from a material having a relatively high thermal expansion and an outer sleeve (44) formed from a material having a relatively low thermal expansion. The heater coil (36) is positioned between the two sleeves. The desired clamping effect is produced by providing at least one axial slot (54) in the inner sleeve. It has been found that during heating, the outer sleeve (44) expands less than the inner sleeve (42) due to the differences in the thermal expansion coefficients of the materials used to form the sleeves. This produces radial forces in the inner sleeve that are redirected into circumferential forces by the axial slot. These circumferential forces in turn cause the slot to close and thereby achieve the desired clamping effect. The band heater-clamp arrangement of the present invention has utility in injection molding machines having hot runner systems for providing liquified plastic material from a source to an injection gate. <IMAGE>
