Patent GB-966604-A (GB)
Title: Improvements in or relating to the production of wear-resistant surfaces of measuring tools or gauges
IPC: C25D15/00
Filed: 1961-03-14
Abstract: <PICT:0966604/C6-C7/1> A measuring tool, e.g. a gauge, is made with a wear-resisting surface by using a matrix as cathode of required size and coated with diamond particles which are then fixed in position and bound together preferably by electro-deposited metal.  The matrix is then removed, e.g. by chemical dissolution, leaving an accurately formed surface.  An aluminium rod of required dimensions is coated at 10 and 11 with an insulating material where coating is not desired, and is used as a cathode immersed in a plating solution 7 of Cu, Ni, or Cr. Diamond dust is applied to the area 12, and then plated with electro-deposited metal to bind the particles together and to the cathode.  This is then removed, and the aluminium dissolved out with alkali, leaving an accurately dimensioned gauge on the concave surface.  If the plating bath is used at temperatures different from that of normal use of the finished gauge, an adjustment of cathode dimensions is necessary. The thickness of the diamond layer is a few tenths of a millimetre.  The diamond powder may first be scrubbed in a drum to remove very sharp points.  The finished surface may be polished with fine diamond powder.  Gauges with a convex working surface are described using a ring of stainless steel of low expansion coefficient, the diamond dust being applied inside the ring.  The process may be applied to forming micrometer plane surfaces, screw threads, or other parts submitted to hard wear, e.g. in textile machinery.

Abstract: 490,078. Coating bakers' goods. HENSMAN, H. April 7, 1937, No. 9876. [Class 28 (i)] An icing-table is provided with a number of centralizing cake-holding members on bars slidably arranged at the underside of the table and connected to a turnable member so that the positions of the holding-members depend upon the angular position of the turnable member. As shown in Figs. 1, 2, table 1 is carried on a shaft 3 journalled in a bearing 5 which is pivoted in the members 6 of the standard 7. A nut 8 and interposed spring or washer 9 lock the table against rotation, when desired, and the wing nuts 12, when tightened, lock the bearing 5 against tilting. The cake-board is held on the table 1 by prongs 15 on bars 14 pivoted to the arms 21 of a member 18 which is rotatable on the shaft 3 and houses a coiled spring 19 secured at its ends to the member 18 and the shaft 3. The bars 14 are provided with milled nuts 17 whereby one of the bars may be pulled out through an opening 16 in the flange 2 of the table, the member 18 being thus rotated against the action of the spring 19 and projecting the other bar 14 equidistantly with the bar being pulled. When released, the bars travel inwardly under the influence of the spring 19. One of the base members 25 of the standard 7 is formed integrally therewith, the other member 26 being pivotally connected therewith to save space in storage. The prongs 15 may be replaced by cranked ends of the bars 14 which engage the cake as well as the board, the cake being thus centred on the board. The flange 2 may be omitted, and the bars 14 guided on the bottom of the table by pin-and-slot connections. The frictional lock provided by the lock nuts 12 may be replaced by a positive lock provided by a quadrant plate on the bearing 5 having a series of holes, any one of which is engageable by a spring-pressed pin or pins on the member or members 6. The cake may be impaled on a central spike or other spikes projecting through the table, and means may be provided for clamping the cake board firmly on the table. The spring for bringing the prongs towards the centre may be dispensed with, friction being relied upon to maintain the prongs in the gripping positions.
