[Also in Divisions A5 and B2] A method of coating small bodies (e.g. pharmaceutical tablets, sweets, seeds, metal magnets, wood chippings, pesticides and fertilisers) by tumbling them in a liquid or semi-liquid coating material (e.g. solution, suspension, emulsion or melt) in a tumbler pan, comprises bringing the bodies to a predetermined temperature before applying coating material thereto and then substantially maintaining the bodies at the said temperature during the application of coating material. The coated bodies may be dried whilst being tumbled and maintained at the said temperature. The bodies may be coated with more than one layer and the bodies may be dried between successive coating applications. The bodies may be heated before and during coating and during drying by means of warm air, steam coils, infrared radiation or ultrasonic vibration. The coating material is preferably preheated. Pharmaceutical bodies may be precoated with a sealing material (e.g. shellac or polyvinyl acetate phthalate), coated with a plurality of sugar layers and finally coated with a layer which can be waxed or polished. A suitable apparatus comprises a rotating tumbler pan 1, a hot water jacketed tank 6 for supplying coating material to the pan 1 via pump 8 and nozzle 9 and a nozzle 36 for directing warm air into the pan 1. Fan 33 supplies air to the nozzle 36 via steam heat exchanger 34, filter 35 and heater 2, the heater 2 being under the control of thermosensitive element 5 in pan 1 to maintain the air at the desired temperature to maintain the bodies at a substantially constant temperature. Thermosensitive element 4 overrides element 5 to switch off heater 2 if the air temperature becomes excessive. A pressure responsive member may be present in conduit 62 for indicating the failure of supply of coating material from tank 6. The pan 1 may be provided with baffles extending along an intermediate zone of the pan 1. The baffles may be of V-shaped cross-section and taper from their centres to their ends.

Title: Process for the galvanic treatment of pieces in bulk and apparatus required for this process
IPC: C25D17/16
Filed: 1967-09-06
Abstract: 1,203,645. Galvanic treatment of pieces in bulk. SEL-REX CORP. Sept. 6, 1967 [Sept. 10, 1966], No.40791/67. Headings C7B and C7F. In a process for the galvanic treatment of pieces in bulk, the pieces are immersed in an electrolyte and subjected to a flurry or flow of fluid of sufficient force to move them and thereby change their respective positions, whereby the pieces are uniformly treated on all their surfaces. The process is applicable to electro-plating, electro-forming, electro-polishing and to the deposition of metal from solutions by electroless displacement by means of galvanic electricity within the electrolyte. Fig. 1 shows a basket 8, 8a which supports pieces to be treated (not shown) and rotates above a radially positioned pipe having jets 13. Electrolyte from within the tank 1 is pumped at 12 through the jets 13 so as to move the pieces as they are brought by rotation of the basket above the radial pipe. A current connection is made to the bottom of the basket via a rotating shaft 3 and basket-support stirrup 7 and another currant connection is made via a conductor 10 to a wire cage 9, 9a, 9b. The basket 8 may be of metal insulated with plastic except for the interior of its bottom 8a or may be of perforated plastic with the interior of its bottom metallized. The electrolyte forced through the jets 13 may be filtered and re-circulated. Instead of re-circulated electrolyte, fresh electrolyte may be used. In another variation, the jets may be supplied with a fluid other than the electrolyte, e.g. a gaseous fluid. Figs. 2 and 3 (not shown) illustrate baskets which are respectively oscillated about a horizontal axis (17) (Fig. 2), and moved to and fro along a horizontal slideway (28) (Fig. 3) over a supply of re-circulated electrolyte from jet tubes. In the Fig. 3 embodiment, the jet tubes may rotate about a vertical axis. Fig. 4 shows pieces 41 supported on metallic netting 40 and moved by a flow of electrolyte indicated by arrows. Current conductors 42 and 44 connect with the netting 40 and a metallic grid 43.
