Patent GB-2039183-A (GB)
Title: Pulsed feedback circuit for an opto-electronic detector
IPC: H03K3/42
Filed: 1978-12-21
Abstract: An opto-electronic detector produces sharp pulses having an amplitude and frequency dependent on the optical feedback factor, the pulses being spaced by intervals in which the radiation-emitting element is entirely extinguished. The circuit comprises a current amplifier (T2) which feeds the radiation- emitting element (D1). This amplifier is controlled by the radiation- receiving element (T1) and by a filter (R1C1) which incorporates a storage element such as a capacitor C1. The control of the amplifier (T2) is effected via an input of the amplifier which has a low impedance in the forward direction and a high impedance in the reverse direction so that increasing current transients in a load circuit (R3) of the amplifier are selectively amplified by optical feedback. The latch circuit comprising T3 allows output pulses to appear across C3 unless there is a rapid drop in the amplitude of successive pulses, when the output is locked to the higher pulse amplitude level. <IMAGE>

Title: Process for the concentration of fibrous material
IPC: C03B37/10
Filed: 1980-01-31
Abstract: Process for the concentration of fibrous material in a mixture thereof with non-fibrous material, by subjecting an aqueous suspension of the mixture to centrifugal force in a hydrocylone to obtain an overflow enriched in fibre and an underflow of reduced fibre content, the aqueous suspension which is admitted to the hydrocylone being the fibre-enriched fraction which results from a preliminary classification in which an aqueous suspension of lowerfibre: non-fibre ratio is submitted to flow under conditions which bring about settling out under ordinary gravitational force of material reduced in fibre content and formation of a fibre-enriched fraction above it.In the process, the underflow flow from the hydrocyclone is incorporated in the aqueous suspension which is submitted to the preliminary classification.The process, which keeps to a minimum the amount of valuable fibre lost, is specially applicable to the concentration of fibres in the fibrous products (mineral wool) formed by disintegrating silicate and like mineral melts, which commonly contain relatively high proportion of granular material ('shot').

Title: Transducer head tracking in prerecorded medium replay unit
IPC: G11B15/467
Filed: 1980-11-25
Abstract: Transducer head tracking is provided in a replay unit (12) relative to a prerecorded medium (10) having at least one track which includes simultaneously occuring information disposed thereon forming a chevron pattern. Separate transducers (16, 18) are disposed within the head (14) for concurrently reproducing the simultaneous information when the head is properly aligned with the track of the prerecorded medium. An error signal is derived in proportion to the phase difference (Y-Z) existing between the reproducing of the simultaneous information form each side of the chevron pattern when the head is misaligned. The error signal is then applied to reduce the existing phase difference and any head misalignment therewith. The phase error signal is produced by comparison of a delayed pulse (triggered by one head) with a ramp signal (triggered by the other), and correction may be by movement of the head or adjustment of the speed of the medium (for cross-tracks on the medium as in helical scan recorders). <IMAGE>
