Patent EP-0261868-A2 (EP)
Inventor: FINLAN MARTIN FRANCIS
IPC: G02B27/44
Filed: 1987-09-16
Abstract: The apparatus comprises a cell 2 containing the sample 1 under investigation. Electromagnetic waves P1,P2 are applied from opposite directions and interfere with one another in the region of the cell to form a standing wave pattern 6. Due to electrostric­tion effects the standing wave pattern causes particles within the sample to concentrate in certain areas in a pattern corresponding to that of the standing wave 6. This pattern of particle concentration forms a grating when seen by an input wave Pin of electromagnetic wave radiation and, provided conditions are correct, results in the generation of a phase conjugate wave Pout. Means (not shown) are provided for measuring the intensity of the phase conjugate wave Pout which gives a sensitive measure of the size of the particles suspended in the sample.

Abstract: A technique is disclosed herein for coupling the joint defined by adjacent ends of a pair of relatively rigid straight pipes forming sections of an overall string of pipes which in operation is intended to bend to a limited extent at the joint. This technique utilizes first and second end segments of the pipes, which end segments respectively include the adjacent ends to be joined and confronting annular faces, actually shoulders, disposed in planes normal to the axes of the pipes. These pipe end segments are joined by a third member, specifically an external nut, such that the confronting faces of the two pipe end segments engage one another and such that when the joint is subjected to limited bending substantially all of the bending forces resulting therefrom are concentrated at the joint in directions parallel with the axes of the pipes, whereby to place the pipe end segments and the joining member in tension only.

Abstract: Circuitry for producing an extremely linear frequency modulated audio carrier for use in the headend of a video signal distribution system, such as a cable television system. A reference oscillator (10) operating at a relatively high frequency, such as the video carrier frequency, generates a signal which is divided down (18) to a relatively low frequency. A voltage controlled oscillator (24) operating at the relatively low frequency is used to frequency modulate the audio signal. After modulation, the audio carrier is upconverted (28, 42) utilizing a signal frequency which is also derived from the original reference frequency, thus providing a stable and linear frequency modulated audio carrier particularly suitable for transmission of stereo program audio.
