Title: Improvements in or relating to abrasive finishing machines
IPC: B24B49/18
Filed: 1962-01-23
Abstract: 922,170. Gear-finishing. MICHIGAN TOOL CO. Jan. 23, 1962 [March 13, 1961], No. 2515/62. Class 83 (3). [Also in Group XXIII] A gear finishing machine comprises an abrasive gear-like honing tool 20 carried by a sliding tool head 26 which maintain close-mesh engagement between the tool and work, the tool head being held in the engaging position by a weight-controlled cranked lever 64, 68. A ratchet-operated lead-screw 48 is also provided whereby reduction of the centre-distance between tool and work due to wear and dressing of the honing tool is automatically conpensated. The work table 12 is traversed relative to the honing tool by a double-acting hydraulic cylinder ; the tool-head 26 contains a variablespeed drive and reversing means providing for reversed rotation of the tool at each reversal of the table 12. Initial lateral adjustment of the tool relative to the work is effected by pinion 38 and rack 40, Fig. 4, carried on the machine frame 8, the pinion being manually rotatable by a shaft 32 having its opposite end projecting from the housing 34 in which it is journalled; a hexagon head is provided on the projecting end. Adjustment of the tool-head 26 to accommodate different diameters of work and honing tools is effected by a hand wheel 54 on the end of the lead screw 48, the head being slidable in guides 44, Fig. 2, on the housing 34. Retraction of the tool-head from the " finishing " to a " clearance " position in opposition to the biasing of the counterweights 70 is effected by a double-acting hydraulic cylinder assembly 72, the limit of rearward movement being determined by the bottoming of the piston at the end of a pre-selected stroke. As the wear of the honing tool necessitates an increase in travel between the finishing and clearance positions of the tool-head 26 an automatic control system housed in a cabinet 79, Fig. 1, effects a predetermined dressing of the tool 20 and concurrently advances the tool-head to a new clearance position whereby the tool wear and reduction of diameter by dressing is automatically compensated. A disc 80 on the lead screw adjacent the hand wheel trips a sensing device 82 after a predetermined reduction of the tool and work centre distance, thereby operating the control circuit to effect the required compensating movement through the hydraulically - operated ratchet mechanism shown in Fig. 5. The sliding pawl-carrier 88 is shown as a single-acting spring-returned fluid pressure actuated member, but it may be alternatively motor- or solenoid-operated. The ratchet-wheel 84 is splined to the lead screw 48 and is provided with a friction-brake comprising a spring-loaded plunger 107, Fig. 4, which bears on one face of the wheel to prevent inadvertent " drift " of the lead-screw. The stroke of the member 88 is made adjustable by a screwed stop 104, and may provide for an advance of the tool-head assembly of 0.001 inch each time the sensing element 82 is tripped.

Title: Etching
IPC: C23F1/00
Filed: 1967-01-18
Abstract: 1,174,285. Etching. FMC CORP. 18 Jan., 1967 [24 Jan., 1966], No. 2657/67. Heading B6J. An article such as a copper foil plastic laminate 10, Fig. 1, is etched in a tank 1, while a small amount of the etchant is passed to a control unit 7. A tape 11, Figs. 1 and 2, of copper foil laminated on to a transparent polyester tape backing, is passed through the etchant in the control unit, so that the copper is removed. The tape passes over a window 19 and between a light source 21 and two photoelectric cells 20, 22. Too rapid etching dissolves the copper before reaching the cell 20, which operates to decrease the inflow of etchant to the tank 1. Too slow etching results in some copper remaining when the cell 22 is reached, and the latter operates to increase the inflow of etchant. Alternatively, the cells may control some other etch factor such as the bath temperature or spray pressure. The etchant may be a solution of ammonium persulphate containing a catalyst amount of mercuric chloride.
