Title: Absorption cell gas monitor
IPC: G01N33/00
Filed: 1980-06-20
Abstract: An absorption cell gas monitor for measuring and monitoring the concentration of a specific gas, such as ozone, in an ambient atmosphere comprises first and second absorption cells (30) and (34) through each of which is passed alternately an ambient sample from an inlet port (12) and containing the specific gas to be monitored and an ambient sample from which the specific gas has been removed by a chamber (14) connected to the inlet port (12), each cell receiving the sample from the inlet port (12) while the other cell receives the sample from the chamber (14). Radiation from a source (60) having a wavelength absorbed by the specific gas is directed through each cell (30), (34) and the intensity of the radiation transmitted by each cell is detected by a detector (66), (68) respectively, the intensities being compared and computed in a stepped sequence in a microcomputer (72) to provide output data on the concentration of the specific gas in the ambient sample. <IMAGE>

Title: Wheels for vehicles
IPC: B60B9/28
Filed: 1980-09-25
Abstract: A wheel for a vehicle comprises a hub 10, a wheel rim 12, and radially deformable means, e.g. telescopic spokes 13, which connect the hub and rim and whose deformation is controlled, e.g. by springs 14. The wheel rim 12 may be flexible so that the part thereof in contact with the ground conforms to the contour of the ground, or may be rigid. The wheel serves to provide or contribute to the spring suspension of a vehicle to which it is fitted, and the adhesion between the wheel and the ground is also improved. Electrical, mechanical, pneumatic or hydraulic means may be provided to successively extend and contract the spokes 13, in such manner as to impart rotation to the wheel. In an alternative construction the spokes are replaced by leaf springs interconnecting the hub and rim. <IMAGE>

Title: Method of bonding composite turbine wheels
IPC: B22F7/06
Filed: 1980-10-16
Abstract: A method of manufacturing a composite turbine rotor assembly from dual materials includes the steps of preforming a turbine disc 18 of powdered metal by direct hot isostatic pressing; machining the external periphery 20 of the disc rim; prefabricating a cast ring 10 of air-cooled airfoil elements having a circular rim 12; shrink-fitting the cast ring 10 to the turbine disc 18; subjecting the interface to a controlled vacuum heat treatment sequence to produce sufficient diffusion bonding at the interface to seal the interface against entrance of high pressure fluids; and thereafter hot isostatically pressing the joined parts under fluid pressure directly applied to the outer surface of the parts so as to press the internal periphery of the ring into intimate contact with the external periphery of the disc until the dual materials are diffusion bonded together. <IMAGE>

Title: Analog balance
Inventor: CHAPPELL JAMES
IPC: G06G1/02
Filed: 1981-09-29
Abstract: A calculating device comprising a rockable cradle 1, 2 having a number of parallel grooves formed in its upper surface, each of which supports a beam 10 provided on at least one of its faces with a calculating scale so that the beam has sliding movement within the groove, along its longitudinal axis. A cursor line which lies normal to the longitudinal axis of the sliding beams is marked on the upper face of the rockable cradle. In typical use a slidable beam having a question scale marked on one of its faces is moved so that a question integer on the question scale registers with the cursor line thereby providing rotating torque about the axis of rotation of the rockable cradle. A further slidable beam having an answer scale marked on one of its faces is moved so as to provide a rotating torque in antiphase direction to that provided by the question scale beam, the antiphase torque being adjusted to such a magnitude that the cradle is balanced and the beams are horizontal. The answer integer may then be read from the answer scale where the same registers with the cursor line. <IMAGE>

Title: Method of manufacturing artificial veneers
Inventor: IIJIMA KUNIO
IPC: B32B7/022
Filed: 1982-01-08
Abstract: An adhesive (2) is applied to one surface of respective material veneers (1) cut out of an inexpensive natural wood. An ink layer (4) is deposited on one surface of respective parting plastic films (3) to form printing sheets (5) and the material veneers and printing sheets are piled and compressed between flat dies (6) with the ink layer (4) opposed to the adhesive (2) to have the ink layer printed onto the respective material veneers (1). The parting film (3) is separated from the respective veneers to obtain printed veneers (7) and a number of the printed veneers (7) are stacked and then subjected to pressure in concave-convex dies (8) to form an artificial flitch (9), which is sliced by a slicer (10) into artificial veneers (11). Very clear annual rings are faithfully presented on the artificial veneer (11) by the ink layer (4) printed onto the material veneer (1) and patterns very similar to grain patterns of such natural wood of a needle-leaved tree as cryptomeria wood are developed. <IMAGE>

Title: Gravity actuated thermal motor
Inventor: DJELOUAH SALAH
IPC: F03G7/00
Filed: 1983-09-26
Abstract: The motor comprises a rotor carrying sealed chambers 2, 3 containing a fluid which vaporises and condenses successively when the chambers pass a hot zone SC and a cold zone SF. Within the chambers are deformable pockets 5, 6 interconnected by a tube 4 and containing a transmission liquid.
