A coating is electro-deposited on to an electrically conductive article from an aqueous coating composition containing organic film-forming material, the article being supported upon a belt-like member which extends in the coating composition and is adapted to electrically connect the article with one pole of the source of electric current. The belt-like member has a flat surface and optionally has projections upstanding from the flat surface so that an article can be supported in the composition either upon the flat surface or upon the projections. The belt-like member may be endless. During the coating the belt may remain stationary or be moved continuously or intermittently. The direction and rate of travel may be varied. The belt may or may not be conductive throughout its length. It may be of metal mesh or net. Electrical supply to the belt may be by a supporting roller or a brush. Unwanted coating which is deposited on the electrically conductive parts of the belt may be removed by solvent, wiping, brushing or abrasive action. The belt may travel into and out of the bath or rotate wholly in the bath and have articles conveyed to and from it e. g, an endless belt of metal mesh provided with outwardly projecting metal spikes may rotate in the bath and articles be conveyed to and from it by a non- conductive conveyer belt which passes over the upper part of the endless belt so that the spikes project upwardly through apertures in the conveyer belt. An article is conveyed into the bath on the non-conductive belt, is then supported on the spikes of the endless belt, coated by electrodeposition, and then conveyed from the bath by the non-conductive belt. The aqueous coating composition may be a solution, dispersion, colloid or emulsion and may contain alkyd resins, epoxy resins, maleinised oils or acrylic resins used alone or in mixtures, optionally together with organic solvents and pigments. Deposition may be anodic or cathodic. After deposition, the coating may be washed, dried and stoved.

Title: Improvements in or relating to the measurement and detection of periodic forces
IPC: G01M1/22
Filed: 1939-04-17
Abstract: 527,788. Electric signalling systems. ROUY, A. L. M. A. April 17, 1939, Nos. 11570 and 11571. Convention dates, April 15, 1938 and March 31, 1939. [Class 40 (i)] [Also in Group XXXIX] In an electric system for measuring and detecting periodic forces e.g. the out-of-balance forces of rotating machinery, one component of the force acts on a piezo-electric crystal which through amplifying equipment controls a cathode ray oscillograph. Fig. 1, shows a system for determining the amplitude of the out-of-balance force of a rotating shaft 5 and the direction in which the force acts. The vertical component P of the force acts on a crystal Q which through amplifiers M, N control the potentials on the plates 1, 2 of the oscillograph O, C and produces an indication A. To determine the position of the shaft 5 when the component force passes through its maximum value and hence the position of the unbalanced mass-an oscillatory circuit C, R, L<SP>1</SP>, is discharged twice per revolution of the shaft 5 by contact points 8, 9, 9<SP>1</SP>, the points 9, 9<SP>1</SP> being mounted on a manually adjustable member 11. The discharge controls the plates 6, 7 of the oscillograph and for any position of the member 11 produces indications B, Fig. 2, at right angles to the line A. To determine the direction of the unbalanced force the member 11 is adjusted through an angle sufficient to position the indicators B at the extremities of the line A. The component force may be communicated to the crystal Q through rollers 22, 23, Fig. 5, carried in a support 14 which communicates vertical movements only to the crystal through a pin 16 and diaphragm 21 having a thickened portion 17. The other end of the shaft 5 may be supported in a similar manner, one of the supports being adjustable longitudinally on a bed-plate in order to facilitate the supporting of shafts of different lengths. In addition to determining the values of mechanical out-ofbalance forces, the forces arising from irregularities of magnetic or electric fields of machines may be ascertained. Parasitic vibrations may be eliminated by providing a second piezoelectric element connected in opposition to the element Q and subjected to the effects of an inertia mass supported by the part 18, Fig. 5. In order to compensate for the difference if propagation speeds of mechanical and electrical waves an inductance is interposed between the two piezo-electric devices. Recording means may also be provided for inscribing on the shaft 5 a mark, the position of which is indicative of the incidence of the out-of-balance force. This record is produced by a contact which may be lowered into engagement with the shaft and is connected in series with the contacts 8, 9, 9<SP>1</SP>. Fig. 1.
