The fabric has a circular bend stiffness in the range of about four (4) Newtons to about seven (7) Newtons, as measured in accordance with ASTM method D4032-94.

Abstract: A device for determining the level of particulate contamination in a fluid power or lubrication system. Between the inlet and the outlet of the device, working fluid passes through a narrow orifice (26) defined between a cylindrical spool (22) and surrounding sleeve (20). As the orifice becomes obstructed by particulate contamination, fluid flow through the device reduces. The contamination level is assessed by measuring the characteristic reduction in fluid flow rate over a period of time. Following the measurement cycle, fluid flow through the device is reversed causing the spool to move relatively within the sleeve to an area of increased bore (40) whereby the enlarged gap allows the release of all trapped contaminants. Following this flushing cycle, the fluid is reverted to the original flow direction, the spool returns to the position within the spool that defines the narrow orifice and another measurement cycle begins.

Abstract: The present invention provides a support structure for a catalyst disposed within an outer containment. Several unique arrangements and connections of supporting struts that form the structure provide a number of significant advantages and improvements. The support structure provides a very low disturbance of gas flow while maintaining a high amount of contact support with catalyst foils. In addition to a high tolerance of thermal gradients and fewer stress concentrations, strong support in radial and axial directions is also provided.

Abstract: A method of preconditioning a non-isotropic composite cylindrical member. The method involves fitting the cylindrical member onto a mandrel having an outside diameter greater than the inside diameter of the cylindrical member and heating the mandrel and cylindrical member to a temperature sufficient to cause thermal deformation of the mandrel and substantially irreversible thermal deformation of the cylindrical member.

Abstract: The gas turbine includes a combustor 10 having a transition piece 18 with its exit end spaced from a first-stage nozzle 22. A brush seal 26 seals about the space between the transition piece and first-stage nozzle. The brush seal includes a sealing cap 28 supported by one of the transition piece and the first-stage nozzle and having a portion 38 overlying the other of the transition piece and first-stage nozzle. A seal ring 30 is secured to the other of the transition piece and the first-stage nozzle and carries bristles 32 projecting therefrom for engagement with the overlying portion 38 of the sealing cap 28 to seal the gap between the transition piece and the first-stage nozzle. In one form, the side face portions of the bristles of the bristle pack form the seal by engaging against a planar sealing surface.

Abstract: Circuit breakers can be used to replace fuses in plant comprising centrifuge machines driven by small three-phase electric motors. The circuit breakers incorporate three bi-metal strips which bend due to the heat produced by current flow. Loss of current in one phase results in unequal bending of these trips. In one arrangement, a light-emitting diode 5 fitted to a first strip 2 produced light to pass through an aperture 8 in a plate 7 on the second strip 3 to fall on a photo-sensitive detector 6 on the third strip 4. Any unequal bending causes the light to be cut-off and the resulting signal can be used to trip the circuit breaker. In some cases the strips are the strips in the circuit breaker.

Abstract: Reinforced composite materials having a thermoplastic matrix and at least 30% by volume and preferably at least 35% by volume of reinforcing filaments, at least 25% by volume being pitch based graphite fibres, are produced having a longitudinal flexural modulus according to ASTM D790-81 of at least 250 GN/m.sup.2. Impregnation of very fragile, inflexible pitch based graphite filaments is achieved using supporting filaments of greater robustness to the abrasion encountered in impregnation processes and, optionally, severing the filaments during the process if products containing only pitch based graphite filaments are required.

The starter motor spindle is provided with a shaft seal and the engine exhaust is fitted with an exhaust pipe in the form of a vertical hairpin or U-tube. The engine air intake box has fitted inside it a horizontally sliding valve that is automatically closed by a vertically-sliding weighted wedge engaging the valve rod.

Abstract: The power supply for an airborne pulse radar includes an unfiltered source of 400 cycle AC power connected to a full wave rectifying circuit including two diodes associated with each phase of the three phase input circuit. In addition, three SCR's are employed for controlling the operation of the rectifiers. During normal operation of the pulse magnetron power supply, the control electrodes of the SCR's are biased to the conducting or enabled state by a small floating DC voltage which is obtained from a small DC power source which includes a rectifier circuit connected to the floating secondary of a low voltage transformer. When a fault is sensed in the magnetron pulse circuitry as indicated by the drawing of excessive current, a switching circuit is activated which removes the enabling voltage across the SCR's, so that the input rectifier circuitry is disabled, thus preventing burn-out of components included in the pulse generation circuitry.
