Abstract: 1,256,943. Grinding. ITEK CORP. 2 April, 1969 [25 April, 1968], No. 17153/69. Heading B3D. An optical surface generating apparatus comprises means 14 for supporting an optical blank 13, means 23 for altering relative elevations on the surface 12 of the blank, drive means for producing relative transverse movement having both circumferential and oscillating radial components between the support means and means 23, and automatic control means 41 for continuously varying the path of the relative movement. The support means consists of a turntable 14 which is rotatable by a motor and carries the blank 13, the surface 12 of which is to be formed to a desired curvature by a lap 23- rotatably mounted on a plate 17 and driven by a belt drive 26 from a motor 25. The plate is mounted for oscillation about a pivot 18 and has a pin 38 engaged by a yoke 37 on a traverse plate 32 reciprocable along a ball slide 34 by a lead screw 35 driven by a reversible motor 36. The operation of the motor is controlled by a sensor unit 42 having a tube which transmits light from a source 72 to a photocell disposed within a housing 46. The reversal of the motor is effected by a control circuit each time the light beam is interrupted by one or other of cams 43, 44, cam 43 being directly driven from a motor 68 arid cam 44 being belt driven so that the cams do not rotate synchronously. One of the cams controls the limit of outward radial movement of the laps 23 on the blank and the other the inward radial movement and the cams are so designed that the lap covers the area of the blank from which most material is to be removed a greater number of times, and hence for a longer period of time, than areas from which less material is to be removed. As the cams do not rotate synchronously, the lap covers a random path over the blank. In another embodiment, the cams do rotate synchronously. Control mechanisms other than cams, for example, mechanical guides, digital counters, magnetic tapes, may be used. In other embodiments, the lap is replaced by the use of ion beams, electrolytic polishing electrodes or vapour columns.

The slurry to be filtered is fed to each frame through passages in its upper part, and the filtrate leaves each plate through passages in its base. The filtrate is collected in a pair of "saucers" 70, and withdrawn through conduits 77. The plates 4 are connected by upper and lower links 8, 9, and are slidably-mounted on two parallel bars 2. The frames 3 are supported on two parallel rails 10, and are movably-connected with the adjacent plates by means of a vertical guiding bar 18 which pass through apertures in links 9. The intervals between frames 3 and plates 4 are closed or opened by moving head 6 forwards or backwards by means of piston rod 25 of oil-pressure motor 24. When a filtration operation has been completed, the frames and plates are separated, and the frames are lowered on rails 10 by means of the piston rod 27 of oilpressure motor 30. The "saucers" 70 are automatically opened at the same time. The cakes are then pushed out of the frames by the movement of members 63 which are actuated by oil-pressure motors 61. The filter belt, which is disposed in a zig-zag between the plates and frames, is caused to travel in direction A over rollers 46, 48, at the top and bottom of each plate, and over additional rollers 49, 50, 55, 56, the movement being actuated by driveroller 52 and electric motor 51. When the discharge of the cakes and cleaning of the belt are completed, the frames are raised, the "saucers" are closed, and the filter medium is again pressed between the plates and frames, so that the filter-press is ready for a further filtration operation.
