Title: Ring laser rotational velocity sensor
IPC: H01S3/083
Filed: 1982-04-13
Abstract: A ring laser rotational velocity sensor has two interconnected resonant cavities sharing one common reflector 50 which has a transparency of 5% at most. One, active, cavity 48, 49, 50 with a gas discharge tube 51 constitutes the ring laser and has an adjustable mirror 48 by which the cavity is tuned. The other, passive, cavity 50, 52, 54 contains a magneto-optic biasing element 53 to avoid frequency locking of the counter rotating beams. The use of a separate cavity allows a Faraday cell of a ferromagnetic garnet, normally too highly absorbtive, to be used as the magneto-optic element. An additional gain medium may also be used in the passive cavity. The passive cavity is preferably formed in a thermally stable block with a slot for the magneto-optic element. Output may be from mirror 49 or from reflection off the ends of the gas discharge tube 51. <IMAGE>

Title: Coating apparatus
Inventor: SAUNDERS NIGEL PAUL
IPC: B05B5/03
Filed: 1982-04-20
Abstract: Electrostatic or electro- gasdynamic coating apparatus includes a coating gun, e.g. for use with dry powder, whose structure defines a through passage leading from an inlet tube (10) operatively connected to a source of particulate coating material to a discharge barrel (12). A central needle cathode electrode (15) is mounted in a constricted region of the passage, its tip being adjacent an annular porous metal anode electrode (25) whose central opening defines part of the passage. A flow of the material is induced along the passage by a first pressurized gas (e.g. air) stream fed from a first supply to enter the passage in the region of the electrodes, in which region the particles receive an electric charge from the latter. At the same time a second pressurized gas stream, which is controlled independently of the first stream, is fed from a second supply through the porous electrode itself to prevent build-up of particles on the acting portion thereof. <IMAGE>
