Patent GB-2018744-A (GB)
Title: Pitch sealing
IPC: H01K1/38
Filed: 1979-03-05
Abstract: The invention relates to the manufacture of an incandescent lamp provided with a hard glass bulb. In contrast to the methods applied up to now, the preceding operation of glazing the current lead-ins is obviated by oxidising the conductors during pinch-sealing; furthermore, after sealing-in a controlled heat treatment is applied.   The heat treatment is preferably performed in a two-zone annealing equipment: in the upper zone the bulb is annealed, while in the lower one the conductors are annealed. This enables the bulb and the conductors to be cooled at different rates. By using the invention for a given matching of the glass and the conductors, the stress conditions needed for sealing-in may be obtained even where there is a considerable difference in the coefficients of thermal expansion of the glass and the conductors. <IMAGE>

Title: Method of detecting changes in dimension of a tool holder or a workpiece holder in a machine tool
IPC: G05B19/401
Filed: 1979-08-21
Abstract: In an arrangement for detecting changes in dimension of a tool holder or workpiece holder of a machine tool, the spindle bar 11 for example is set so that a predetermined point thereon which is unaffected by changes in dimension caused by thermal expansion and contraction is disposed at a preset machining co-ordinate on a datum axis parallel to the spindle axis 12. In order to detect and compensate for changes in dimension of the spindle bar 11 along the datum axis, the numerical control system is programmed on command to move the spindle bar 11 along the datum axis until an end surface 15 thereof is detected by a probe 16 of a detector 14, and the position of said predetermined point at which such detection takes place is measured. This measured position is then compared with the expected value and any difference is applied to the preset machining co-ordinate as a compensation. Changes in dimension of a tool holder relative to a workpiece holder in more than one direction may be accommodated. <IMAGE>
