Patent DE-3920194-A1 (DE)
Title: Local correction of blown film thickness using variable air flow
IPC: B29C48/10
Filed: 1989-06-21
Abstract: In a process for the fine correction of the thickness profile in a blown film tube, the flow of cooling air is varied in individual regions of the film bubble periphery.  At least part of the cooling air is introduced to the bubble by a circumferential slot which is divided into individually fed segments. The control of the additional cooling air is by means of radial blowers. In this manner it is possible to accurately control the cooling action and therefore film thickness in individual circumferential regions of the film bubbles. Equipment for achieving fine control of the additional air is also described.

Patent DE-4104041-A1 (DE)
Inventor: BAAS DIETER
IPC: G11B27/10
Filed: 1991-02-09
Abstract: Recorded on the so-called lead-in track of a compact disc is the contents list of the disc. The data stored in the contents list are divided into several blocks. Several blocks containing the same data are recorded in series on the CD for redundancy purposes. A CD player reads the whole contents list, reading all the blocks, even the redundant ones, one after the other, by moving a scanning device along the spiral data track. In order to reduce the time taken to read the contents list, the invention calls for the scanning device, when reading the data making up the contents list, to jump one track outwards or inwards when it has read a block. This means that the scanning device no longer reads all the redundant blocks, but only a small proportion of them, thus considerably reducing the time taken to read and store the data making up the contents list.
