IPC: C25D11/22
Filed: 1968-11-23
Abstract: A coloured anodic oxide coating free from spalling is produced on an aluminium metal or base alloy surface by anodizing the surface, e.g. in 15% H 2 SO 4 solution using D.C., then colouring the anodized surface in an aqueous acidic bath containing a Ni, Co, Cu, Ag or Pb salt, or an oxide or salt of Se, Te or Mn, and including, to reduce spalling, at least 100 ppm of Mg or (except where the bath includes Ni or Co) Al ions, using A.C. and a counter-electrode e.g. of graphite or the same metal as the colouring ions in the bath. Preferably 2-40 g/l or MgSO 4 7H 2 O or Al 2 (SO 4 ) 3 18H 2 O is added to the bath. Examples of bath compositions are: (1) nickel or cobalt sulphate, boric acid, magnesium sulphate or borate, and optionally ammonium sulphate (or as nickel ammonium sulphate) (2) copper sulphate, sulphuric acid, and magnesium or aluminium sulphate (3) lead acetate, acetic acid, and magnesium or aluminium acetate (4) silver nitrate or sodium selenite or tellurite, aluminium sulphate, and sulphuric acid and (5) potassium permanganate, and magnesium or aluminium sulphate.

Title: Grinding machine for carbide cutting elements
IPC: B23D73/00
Filed: 1976-11-23
Abstract: A grinding machine particularly for grinding the teeth on a carbide cutter. The machine includes a carriage swingably mounted on a frame for oscillation about a pivot axis. The carriage has a grinding wheel mounted thereon and rotatably driven by a motor which is also mounted on the carriage. The wheel is rotatable about an axis which is approximately parallel to but spaced from the pivot axis. A feeding mechanism projects outwardly from the front face of the grinding wheel at an angle of approximately 45 DEG relative to the rotational axis. The feeding mechanism releasably supports a carbide element. The feeding mechanism is linearly advanced toward the grinding wheel in an intermittent steplike movement which is synchronized with the oscillating movement of the carriage so that the grinding wheel cuts a groove across the carbide element during both the forward and return swings of the carriage. The grooves cut in the carbide element form cutting teeth therebetween, which teeth have a rounded convex configuration due to the engagement of the carbide element with the grinding wheel at a location between the pivot and rotational axes.

Title: Toner powder supply system
IPC: G03G15/08
Filed: 1978-02-07
Abstract: The invention relates to a toner replenishment system for a dry toner developer unit in a photocopier. Toner is introduced into the developer unit in a canister which is closed at one end and has near its other end an extractor plate mounted for rotation around the axis of the canister and for axial movement along the canister, the toner powder being disposed between the closed end and the extractor plate.

Title: Improvements in or relating to machines for the wet treating of fabrics
IPC: D06C17/02
Filed: 1979-02-16
Abstract: A washing and milling or fulling machine comprises squeezing rollers 4, 11 and a fabric guide roller downstream of a fabric guide frame 2. A driven belt conveyor 16, acted on by a counter-weighted pressure roller 18 uniformly feeds the continuous and endless fabric web T made by a plurality of pieces of fabric sewn together towards and between the squeezing- rollers 11, 4.
