Title: Conversion of laser frequencies
Inventor: BROWNE DR P F
IPC: H01S3/113
Filed: 1981-07-09
Abstract: An optical cavity which comprises a beam expansion section (as in an unstable resonator) and also a beam reduction section (which may be the expansion section used in reverse) has considerable advantages for achieving non-linear effects if the amplifying medium is in the beam expansion section and the non-linear medium in the beam reduction section, and specifically near to the axis of the cavity. One of many possible realizations of such a cavity is described in the specification, and its advantages described for off- resonance stimulated Raman scattering. The advantages for achieving high laser beam intensity are (i) geometrical intensification by a factor M<2> of the amplified expanded beam, where M is the magnification of the reducer considered as a telescope, (ii) trapping of the stimulated emission within a high Q cavity so that the desired non-linear process becomes the dominant loss mechanism, and (iii) the possibility of automatic mode- locking by using an intracavity bleachable absorber at the laser frequency. <IMAGE>

Patent GB-2128903-A (GB)
Title: Separating impurities from a gas
Inventor: ALDERTON GEOFFREY WALTER
IPC: B04B5/12
Filed: 1982-09-30
Abstract: A method of separating solid or liquid impurities from a gas involves causing the impurity-bearing gas to flow axially along a path through a gas centrifuge whilst being subjected to a radially-outward force derived from the gas centrifuge in operation, collecting the impurities on the wall of the centrifuge rotor or on the wall of the stationary casing enclosing the rotor, and recovering the impurities, the stripped gas being allowed to flow outwardly generally axially from the centrifuge. Apparatus for performing the method consists of a driven rotor (3) in a stationary casing (1), gas being introduced into the casing (1) at an inlet (11) and being constrained to flow axially into the rotor (3) at the lower end, where vanes (8) impart rotational flow to the gas and impurities are deposited on the wall of the rotor (3) for subsequent recovery. Stripped gas leaves the rotor (3) generally axially at its upper end, where moving vanes 7 and fixed vanes (9) cooperate to convert a part of the rotational energy of the gas into a pressure rise. <IMAGE>

Title: Air supply ceiling
Inventor: NEUHAUS GERHARD
IPC: F24F7/10
Filed: 1982-10-26
Abstract: An air supply ceiling, e.g. for an operating theatre, may seriously interfere with the positioning of lighting or other ceiling mounted equipment since it is not possible to pass a suspension element through the air supply ceiling without serious risk of allowing non-sterile air to by-pass the sterile filter forming part of the ceiling. According to the present invention an air supply ceiling includes an air duct (15) having an air inlet with a sterilising filter (19) through which air is blown is indicated by arrow (21). This duct (15) is mounted in an aperture in a false ceiling (12) and the lower wall of the duct 15 is provided with a series of areas of or other ceiling mounted equipment perforated plates and flow compensators in the form of a foam mat. Thus, where suspension elements (61, 71) pass through the lower wall, there is no risk of leakage of non-sterile air since the air is already sterilized. Holes for the passage of suspension units (61,71) through the upper wall of the duct (15) are easily sealed. <IMAGE>

Title: Clamping assembly
Inventor: PARTRIDGE DAVID
IPC: F16B2/14
Filed: 1982-10-27
Abstract: A ring 2 is locked to a tube 1 of slightly smaller diameter than the internal diameter of the ring by means of a generally U-shaped component 8 having two limbs 9, 10 capable of resilient displacement in relation to one another. The limb 9 co-operates with an axially inclined surface 5, located in a recess 4 in the interior of the ring, so that axial movement of the component 8 in relation to the ring 2 produces a wedging action forcing the limb 9 against the surface of the tube to establish a frictional lock. The other limb 10 engages the outer surface of the ring 2 and is formed with a shoulder 16 co-operating with a corresponding shoulder 17 on the other surface of the ring to hold the component in the locking position. <IMAGE>

Patent GB-2112092-A (GB)
Title: Hydraulic actuating system
Inventor: REEVE ANTHONY JOHN
IPC: B60T11/32
Filed: 1982-11-25
Abstract: An agricultural or industrial tractor (100) has a transmission casing (T) and/or back axle housing (16, B) which acts as a sump for fluid used to lubricate the transmission and/or back axle and to provide a reservoir of actuating fluid for hydraulically actuated functions. The tractor also includes an hydraulic actuating system, such as a braking system, having a slave cylinder (10, 11) with a bleed facility (41, 42, 43) with a return passage (44) which communicates with an opening (45) in the transmission and/or back axle housing (16), so that on opening of the bleed facility (41, 42, 43) the actuating fluid of the actuating system can be bled back into the housing (16) via the return passage (45). A master cylinder (21, 22) of the hydraulic actuating system may be charged from a hydraulic power system of the tractor which uses the same actuating fluid, for example the power steering system (30, 32, 33, 35, 36), at a pressure insufficient to operate the slave cylinder (10, 11). This will ensure that when the bleed facility (41, 42, 43) is opened a purging flow of fluid through the return passage (45) is ensured from the pump (30) of the power system. <IMAGE>
