The central recess 2, Fig. 4, in the rectangular frame has on either side hollow pillars 3 one of which houses a balance weight 8 for the vertical slide while the other serves as a housing for electrical equipment operating in the manner described in Specification 522,413. The compartment 30 of the frame houses the driving mechanism and is formed with a sloping roof portion 11 which carries the upper bearing 10 of the work spindle 9. The closed base 31 of the frame has an upstanding part 14 carrying the bottom spindle bearing 15. The hobbing head 7 on the cross slide overhangs the roof 11 which prevents cuttings from reaching the gearing and diverts them to an opening 16a leading to a cuttings chamber 16 from which the coolant flows through a passage 16b into a well whence it is recirculated. Lubricating oil is pumped from a well 1a to a distributing chamber from which pipes lead to the various parts to be lubricated. The work spindle is hollow so that-swarf may also pass through the spindle into the housing 14. The change gears are accessibly housed in a compartment 18 closed by a plate 18a. The vertical slide is operated by a screw 19 driven by bevel gears from a feedshaft 21, Fig. 11. The hob spindle is normally driven from themotor 27 through shaft 42, change speed gearing 44, shafts 43, 24 bevel gears 38, splined vertical shaft 23, bevel gears 22, shaft 34, and other gearing. The shaft 24 is also connected through change gears 46 to the work spindle 9. Further change gears 47 connect the work spindle to the feed shaft 21. When cutting helical gears, the rotation of the work is. modified through the differential gearing 45 which is driven from the feed shaft 21 through gearing 48 and change gearing 49. In order to obtain a quick return feed an electrically operated plunger controls two clutches 39, 41.

Abstract: 1312818 Optical data store LICENTIA PATENT-VERWALTUNGS-GmbH 21 July 1970 [31 July 1969] 35291/70 Heading G4M A data storage system comprises a hollow cylinder adapted to guide at least one tape along its inner surface, a rotating mirror inside the cylinder passing a beam from one end of the cylinder to the inner surface of the cylinder or vice versa. One or more tapes are passed longitudinally or helically along the inner surface, being held by suction, and optionally electrostatic charge as well (plastics coating on cylinder). Digital data is written as presence or absence of discoloration (or perforation) on the tapes by a laser beam applied from one end of the cylinder via a lens and the mirror on to the recording position. An organic recording material is used in the case of discoloration recording. For readout, a beam is applied in the opposite direction through an aperture in the cylinder or a cylindrical lens forming part of the cylinder wall, from a ring light source or a localized source. In the latter case, the beam goes via a mirror on the rotating shaft supporting the other mirror above, and two annular mirrors, to be applied to the cylinder. The read-out light from the tape goes via the first mirror, a lens and a biprism (or mirror triad) to photodiodes. The biprism (or mirror triad) is rotated at half the mirror rotation speed in the opposite direction to counter undesired rotation of the image (in the helical tape case). A column of photodiodes is used bridging several adjacent data tracks. Address information recorded allows selection of the appropriate track. During writing, an unmodulated control beam accompanies the writing beam to read the information recorded, for a check comparison.
