Patent GB-2060950-A (GB)
Title: Adaptive stylus translator
IPC: G11B21/04
Filed: 1980-10-13
Abstract: An adaptive eg video disc record stylus kicker (46) system for inducing limited pickup or stylus (14) translations radially across the disc record (12). Control circuitry (54) responsive to disc track and disc angular sector identification signals automatically calibrates the kicker activation signals (51) to produce a desired kicker induced stylus translation. That is, the control circuitry responsive to these track identification signals and to player commands (53) evaluates the error between actual kicker induced stylus translations and the programmed kicker induced stylus translations. A microprocessor (56) establishes a table containing kicker control signals for driving the kicker in each sector of the disc. For a given kicker induced stylus translation, the error is calculated between the actual stylus translation and the programmed stylus translation and the control signal for the respective sector is adjusted accordingly. Subsequently, the control signals for each of the other sectors are altered proportional to the adjustment made to the particular control signal in accordance with a correlation function. The system operates to correct mistracking (identification signals do not appear in the correct sequence) due, e.g. to record defects. <IMAGE>

Title: Projector or viewer for cine film having the facility of single- frame operation
IPC: G03B21/16
Filed: 1981-02-20
Abstract: A film guide track 3, 5 guides a cine film 7 between a lamp 1 and a projection lens 2, and is composed of a relatively flexible guide 5 nearer the lens and a relatively rigid guide 3 nearer the lamp. A projection window 4 in the guide track permits light to pass from the lamp 1 to the lens 2, and includes a planar glass plate 8 on the guide 3. During normal cine operation, the heat from the lamp 1 causes the film to bow convexly thereto and into contact with the plate 8. When the projector or viewer is used to project or view a single frame of the film, excessive bending of the film which would otherwise throw the projected or viewed image out of focus is prevented by the glass plate 8. This can be assisted by streams of cooling air from a ventilator 6 directed respectively onto the lamp-facing surface of the glass plate 8 and between the guide 5 and the projection lens 2. <IMAGE>

Title: Method of fabricating structures
IPC: E04B7/10
Filed: 1981-04-28
Abstract: A method for fabricating structures such as domes or roofs.

Title: Discrete fourier transform circuit
Inventor: ROSSITER TIMOTHY JOHN MILES
IPC: G06F17/14
Filed: 1981-11-24
Abstract: In a transmultiplexer, which is an interface between a number of PCM highways and an FDM group, the conversion between PCM and FDM involves first converting the PCM words into their linear form and filtering them, applying them to a circuit which performs a discrete Fourier transform (DFT) on them followed by a second stage of filtering. An efficient implementation of a DFT is described which reduces the number of multiplications required by making use of certain symmetry properties in a DFT matrix. The whole can be used "backwards", as it were to give an inverse Fourier transform as needed for the FDM-PCM conversion. <IMAGE>
