A tool 96 mounted on a head 94 cuts the block surface 98 into an accurate epitrochoidal surface and is supported to do this by a connecting bar or shaft 92 eccentrically and rotatably mounted in a hollow spindle 68 itself concentrically rotatable about a second axis "Y" by means of a gear 74 driven by the motor 86. The bar 92 has an axis "B" which is parallel to the other axes and is located on the same line as the contact of the tool 96 with the cylinder 54. The bar also has a guide member 106, Fig. 6, which engages between pairs of rollers 110, 112 on an oscillating plate 108 provided with a journal 14 having a third fixed axis "Z". In operation, the cylinder is advanced by the lead screw 46 and rotated about the first or "X" axis by the gear 58. The hollow spindle 68 is rotated at the same time about its own or second axis "Y" by the motor 86 rotating gears 76, 74, and simultaneously the bar 92 is given an eccentric revolution by the rotation of the hollow spindle and the action of the plate 108 engaging the guide 106 at the end of the bar. Should the tool be required to trace or cut a two lobed cavity in the cylinder 54, then the gear 74 which drives the hollow spindle 68 must rotate about the second or "Y" axis at twice the speed of rotation of the gear 58 about the first or "X" axis, and the distance between the "Y" axis and the "Z" axis, Fig. 6, must be one third of the distance between the "X" and "Y" axes. Other speeds and distances must be arranged for three lobed cylinders by exchanging the gears 88, 90 which are mounted on an adjustable plate and by replacing the oscillatable plate 108. The handstock and the block 54 are progressively fed towards the tool until the entire cylinder surface 98 has been traversed.

Abstract: 1288402 Controlling mixing by temperature and power consumption GEORG FISCHER AG 30 Sept 1969 [7 Oct 1968] 48091/69 Heading B1C [Also in Division G3] The moisture content of granular material, e.g. moulding sand, is controlled in a sand processing arrangement as shown by automatic adjustment of a valve 5 to control the amount of water added to sand in a mixing drum 1 via nozzle groups 2, 3, 4, and in dependence upon the temperature of sand being fed to the drum on a conveyor 13 and upon the mechanical load on the drum drive motor 17. The power input to the motor, or alternatively its drive torque, is determined by a transducer 18 as a measure of its mechanical load. The output of 18 is fed to a control device 19. The output of 19 is fed to a regulator device 16 together with a signal from a transducer 15 coupled to a temperature sensor 14. The regulator 16 accordingly operates on a positioning member 20 which adjusts the valve 5 to vary the total quantity of water/unit time delivered to the drum. A riser conduit 6 having upper and lower water level sensing switches 7, 8 respectively functions as a water pressure sensor. The switches 7, 8 in cooperation with a control device 9 operate to maintain the water inlet pressure to the nozzle groups 2, 3, 4 substantially constant between limits defined by the switches. Thus when the pressure is such that water level reaches switch 7, the control device 9 switches in one nozzle group and when the level falls to switch 8 the device 9 switches out a nozzle group. Thereby droplet size is said to be maintained substantially constant irrespective of water quantity being delivered.
