Abstract: In an X-ray tube rotary anode having a supporting body (1) of molybdenum alloy, a target (2) of tungsten alloy, and a rough tungsten layer, applied by flame spraying to the whole surface of the anode except the focal path (4), for improving heat radiation, the rough tungsten layer does not adhere well to the tungsten alloy target, and particles of the rough tungsten layer may become detached in use, degrading the performance of the X-ray tube. To alleviate this problem, the whole surface of the anode, except the focal path (4), is blasted with steel grit, steel grit particles embedded in the anode are removed with acid, and the whole surface of the anode, except the target (2), is coated with a rough tungsten layer (3) by plasma spraying.

Abstract: A coating process in which an article to be coated is immersed as an anode in a dispersion of a film-forming material stabilized by non-ionic stabilization and an electric current is passed between the anode and another electrode immersed in the dispersion. The dispersion is destabilized in the region of and is deposited on the anode by interaction between a moiety providing the non-ionic stabilization (e.g. of polyethylene glycol) and a further interactive moiety (e.g. carboxyl groups present in polymethacrylic acid) present in the dispersion. Suitable coating compositions and coated articles are defined.

Title: Paper coating method and apparatus
IPC: B05D1/26
Filed: 1980-11-06
Granted: 1986-08-06
Abstract: This invention relates to a method, and apparatus of the blade type, for applying a coating material to a web of paper. A conventional coater of the blade type includes means for applying coating to a paper web supported and carried by a resilient backing roll (24), together with a flexible doctor blade (98) located some distance from and on the trailing side of the applicator (20), which serves to level the applied coating. In order to achieve low coat weights, i.e. in the order of 3 to 4.5 grams per square metre per side of paper, it is necessary to increase the pressure of the blade (98) against the web (26), which results in a high rate of wear, and increases the possibility of web breakage and streaking caused by foreign particles being caught between the blade (98) and the web (26). The present invention utilizes a reservoir (80) of liquid coating material between a forward liquid seal and a rearward doctor blade (98) spaced a short distance from the seal. The coating material is applied under pressure so as to form and maintain the liquid seal. This provides a short dwell time, low coat weights, low blade pressures, and excellent results.
