Title: Fibre optic scanning system
Inventor: IRAVANI MEHDI VAEZ
IPC: G01B9/04
Filed: 1986-10-07
Abstract: The system includes a coherent radiation source (1) feeding a pair of fibre optic light guides by way of a coupler (3). The radiation from the guides is recombined by a second coupler and focussed by a Nomarski objective (14) on to a test surface. Reflected radiation is returned through the couplers and the light guides to a detector (5), e.g. a photodiode. The system can be used as a SAW probe by detection of the interfering clockwise and anticlockwise propagating radiation, a polarisation controller 18 being incorporated in one of the guides (6). For use as a differential phase microscope the objective (14) is either positioned at 45 DEG  to the incoming radiation which has the same polarisation in both guides or the objective is positioned with its optical axes coincident with two incoming orthogonally polarised beams so as to produce two adjacent foci on the test surface. In this latter case a PZT phase modulator 17 is used. <IMAGE>

Title: Control of fluid dispensing
Inventor: LOWE MICHAEL ANDREW CHRISTOPHE
IPC: B05B12/12
Filed: 1987-09-29
Abstract: Fluid such as a lubricant is automatically dispensed when a sensor (12A, 12B) monitoring an operation, e.g. performed by a machine tool, signals that lubricant is required.

Patent GB-2218545-A (GB)
Title: Recursive processor for multiplication
Inventor: KNOWLES SIMON CHRISTIAN
IPC: H03H17/02
Filed: 1988-04-06
Abstract: A recursive processor suitable for infinite impulse response (IIR) filter applications incorporates multiplier cells 16 connected to form rows 12 and columns 14. Each row is arranged to multiply by a coefficient. It begins with accumulator cells 18 and 20, and continues with multiplier cells 16 arranged to multiply by individual coefficient digits and disposed in descending order of digit significance. Columns 14 other than the first column 141 begin with a multiplier cell 16, and the higher significance columns 141 to 144 terminate at respective accumulator cells 20. Any intervening multiplier cells are arranged in ascending order of multiplier digit significance. The multiplier and accumulator cells 16 to 20 operate in accordance with signed digit number representation arithmetic involving digit redundancy. They generate sum and transfer digits for output down columns and along rows respectively to neighbouring cells in the direction of increasing coefficient digit significance. The cell arithmetic employed makes it possible to compute results most significant digit first. Each result digit is recycled when formed to provide a multiplicand digit input for all multiplier cells of a respective row selected in accordance with result digit significance. The processor is also arranged to add successive non-recursive input terms to multiplier products. This provides for the processor to provide a first order IIR filter section, and two cascaded processors provide a second order IIR filter section. The recursive processor effects the recursive computations required for a first order IIR filter section with latency of only two clock cycles irrespective of input word length. <IMAGE>
