Title: Reflectors providing constant angle between input and output beams
Inventor: POLLITT KENNETH RODNEY
IPC: G02B17/00
Filed: 1987-12-24
Abstract: A reflector is arranged so that an output beam and an input beam remain at a constant angle to each other for at least a limited range of angles of incidence of the input beam. The device comprises a thin collimating lens (2) through which the beam passes, a pair of opposed reflectors (4, 8) positioned equal distances on opposite sides of the collimating lens and a tranverse reflector (6). The input beam passes through the lens and, after reflection at one of the opposed reflectors, is focussed at the surface of the transverse reflector and then passes out again through the lens after reflection at the other opposed reflector. The lens may be replaced by a concave mirror or other optical element capable of focussing the input beam and collimating the output beam. The reflectors may be constituted by the surfaces of a solid block of transparent material. <IMAGE>

Title: Frequency response analyser
Inventor: SAYERS BRIAN
IPC: G01R27/28
Filed: 1988-04-29
Abstract: In a frequency response analyser capable of testing a system under test at a higher frequency F derived from a signal generator providing a relatively higher frequency F/K. A reference signal of frequency F-C is supplied to a mixer where it is multiplied with the return signal of frequency F to provide a fixed frequency output C. An analysing portion of the frequency response analyser is therefore required to operate only at this fixed frequency C and may provide an output in any suitable form, for example displays of magnitude and phase against frequency as F/K is varied. The present invention overcomes the problem of providing a VCO based signal generator capable of operation at very low frequencies.

Title: Peak hold circuit
Inventor: UMEYAMA TAKEHITO
IPC: G11C27/02
Filed: 1990-06-13
Abstract: In a peak hold circuit suitable for use in a tracking control arrangement of a disc drive, first and second sample and hold circuits Q7a,C3a; C5a, C30a are respectively charged under the control of a mode switch 4a, 30a in the sampling mode to first and second voltages corresponding to the peak value of a servo signal at 19, 1b and a reference voltage at E1a and these voltages are then held in the holding mode. A dc offset of the first voltage resulting from a slow discharge through a buffer 5a is matched by a similar offset in the second voltage and an output without an offset is obtained after subtraction between the first and second voltages. Capacitors C3a, C30a are charged during a sampling period spanning several cycles of the servo signal and any errors in charging to voltages less than the peak values due to a shorter sampling period are also cancelled by the circuit. Servo signals at 1a, 1b are full wave rectified at 2a and applied via a buffer Q6a to the sample and hold circuit. <IMAGE>

Title: Eliminating cumulative thickness errors in a wound coil of plastics foil
Inventor: PREDOHL WILHELM
IPC: B29C48/92
Filed: 1991-03-15
Abstract: Plastics foil as produced e.g. extruded, has a thickness error profile across its breadth, comprising systematic positive thickness and/or negative thickness errors which superimpose in a wound coil of the foil, to produce a non-cylindrical coil. A substantially cylindrical coil is obtained by determining the thickness error profile by measurements of the foil, or of the coil, and by means of a computer the extended thickness of the plastics foil is either increased over at least parts of the zones between the error zones having positive thickness errors, in proportion to the positive thickness error, or similarly decreased between the zones having negative thickness error, the thickness increase and decrease preferably being effected in alternation. The foil may be extruded flat, or as a blown tube. The foil thickness may be measured by transmission photometry, or indirectly by measuring the coil contour by laser beam metrology, or mechanically.
