Inventor: BATCHELLOR CHARLES ROBERT
IPC: G01N21/35
Filed: 1985-08-09
Abstract: An optical sensing arrangement for measuring gas concentrations comprises a light source (7) for producing light of relatively wide bandwidth and a Fabry-Perot cavity scanning and detecting arrangement (1-4,9) for scanning a relatively narrow part of the bandwidth to detect any attenuated wavelength components due to absorbtion of light by the presence of gas in the light path (3) and to provide an electrical output (14) which may be processed by processing means (6) to give an indication of the level of attenuation (15) of the wavelength corresponding to the level of gas concentration in the path of light derived from the light source (7). The scanning is accomplished by a sweep signal driven piezoelectric device 4 supporting one face 2 of the cavity. As shown, the gas is located in the cavity but is an alternative embodiment, the gas is sensed at a remote location connected by light fibres to a source and scanning Fabry-Perot cavity. <IMAGE>

Title: Hydrotherapy apparatus
Inventor: BRUETON JOHN THEOPHILUS
IPC: A61H33/02
Filed: 1985-08-27
Abstract: The apparatus comprises a bath 1 having a number of jet outlets 20 each supplied by a length of tubing 19 from a manifold 10. A blower 6 feeds air to the manifold via a flow control valve 8 and a non-return valve 9, and water is fed to the manifold via a flow control valve 13 from an external hot water supply, e.g. the supply to the hot tap 2. The manifold contains an inner water jacket 22 with branches that travel within the lengths of tubing 19 where the hot water is added to the air flow. The jets thus feed a mixture of air and hot water to the bath so that the temperature of the bath water can be maintained indefinitely. <IMAGE>

Title: Method and agent for detection of thiols
Inventor: HEIDENREICH HOLGER
IPC: G01N33/52
Filed: 1988-01-28
Abstract: A method and agent for the detection of thiol groups is presented in a system or formed in a step preceding the detection reaction. This formation can be effected by chemical reactions, such as, for example, reduction of disulphides, or biochemical reactions, such as, for example, thioester hydrolysis by esterases. Fe<3+> ions are reduced to Fe<2+> ions by the thiol groups. The Fe<2+> is then detected with suitable complex ligands, such as ferroins, cuproins and terroins. The complex ligands may also include hydrazones, imines, phenols and tetrazines.

Title: Flying backing piece for woodworking machinery
Inventor: LENTON FRANK
IPC: B27G19/10
Filed: 1988-06-21
Abstract: A flying backing piece (10), for preventing splintering in tenon cutting machinery, is guided for reciprocal movement by a non-linear cam track (42). The backing piece is moved by a ram (20) acting on the first link (16) of a two-part linkage (16, 18) connecting the backing piece to a housing frame (14) of the machinery. The cam track (42) is formed in a cam plate (44) which is adjustable in a direction (A) perpendicular to the last component of actuating movement of the backing piece (10). Adjustment which is preferably by a lead screw (60, Fig. 2), permits compensation for wear of the backing piece in use. By advancing the backing piece into the teeth of the rotary cutter, the backing profile is renewed by the rotating teeth which simply cut a new profile. In use, the backing piece moves into contact with the trailing face of a timber workpiece as the workpiece passes through the work station. <IMAGE>

Title: Device for the obturation of a nozzle for a gas generator of a flying projectile
Inventor: BERNARD MARC
IPC: F42B15/36
Filed: 1990-12-06
Abstract: The invention provides the storage of a quantity of energy at the end of combustion of a gas generator equipping, for example, a flying projectile. This energy, which is not required for the motor function of the projectile, may permit, for example, a self-ejection of the compartment containing the gas generator. To achieve this, the invention relates to a device for the obturation of at least one opening of a gas generator comprising a plug (10) and a system (19, 21) for fastening the plug to the gas generator. In the course of the combustion of the product contained within the gas generator, the fastening system is released; this permits the plug (10), which is positioned close to the opening, to move under the effect of the reduced pressure created at the location of the opening by the combustion of the product, and thus to come to obturate the opening. <IMAGE>
