Abstract: An optical inclination sensor 10 is provided having at least one mass 40 attached to housing 42 and moveable with respect to the housing as the mass and housing are rotated about one or more axes (52, 54, Fig.5). Optical strain sensors 44, such as fibre Bragg gratings, are disposed at various locations between the mass 40 and the housing 42 so that as the mass moves with respect to the housing, each one of the strain sensors 44 are placed in compression or tension. The housing 42 can be a generally u-shaped housing having two arms 46 and a base section 48 with the mass disposed within the housing. Alternatively, the housing includes a first beam (60, Fig.8), and the mass is a second beam (62, Fig.8) arranged generally orthogonal to the first beam and pivotally attached thereto. The optical strain sensors 44 are disposed between the first beam and the second beam and are placed in tension or compression as the second beam pivots with respect to the first beam. Alternatively the inclination sensor 10 comprises at least one reflective surface (12, Fig.1) and at least two separate optical fibres (14, Fig.1) having ends spaced from the reflective surface. As the reflective surface tilts with respect to a pre-determined reference position the gap lengths (20, 22, Fig.1) between the fibre ends and the reflective surface change and the differences in these gap lengths is used to calculate an angle of inclination (26, Fig.2) with respect to the reference position.

Title: Plumbing tool
Inventor: RIPPOLONE JOSEPH D
IPC: F16L21/035
Filed: 2003-11-04
Abstract: A plumbing tool 10A includes an elongated hollow shaft 12A, 12A' and a resilient member 16 attached to the shaft adjacent a shaft end. The resilient member 16 extends radially outward and is sized to closely fit within a pipe (24, figs 2A-2E) inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. The shaft comprises a first section 12A to which the resilient member 16 is attached, and a second section 12A' which is joined at an angle to the first section. The resilient member 16 is preferably an annular disc. A valve (V, fig 2C) may then be passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the valve is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users.

Title: Resumption of interrupted broadcast distribution to a mobile communication device
Inventor: KURIHARA SHINICHI
IPC: H04N21/6375
Filed: 2008-08-04
Abstract: It is assumed that a reception processing unit receives a broadcast program in accordance with tuning based on the user's specification. In this state, a non-viewable state or interruption detection processing unit monitors occurrence of a non-viewable state (interruption) from an acquisition state of reception data. When the non-viewable state occurs due to a certain factor, a non-viewable state accumulation unit accumulates information on the non-viewable state. When the factor of a viewing interruption is solved and a user makes a request for service provision, the processing unit connects to a distribution apparatus to report content of the non-viewable state, and receives distribution of a relevant content, thereby the processing unit becomes able to resume interrupted broadcast content.

Abstract: 427,675. Bottles. BARTON, C. W., 37, Madison Avenue, New York, U.S.A. April 3, 1934, No. 10068. Convention date, April 6, 1933. [Class 125 (i)] [See also Group VI] Ampoules and other containers for use in storing the ingredients of, and preparing fresh solutions immediately before use, comprise an outer container for liquid and a pellet-like body freely movable within said container and formed with a recess or chamber within which a second ingredient is confined by a membrane which can be ruptured when the pellet-like body is moved against a pin or the like associated with the closure of the outer container. Fig. 1 shows an ampoule for use in a hypodermic syringe ; this comprises the usual rubber plugs 2, 3 and encloses a pellet 6 formed with a recess 7 closed by a membrane 10. The pellet may be brought by a throwing movement into contact with the double ended hypodermic needle, which projects through the plug 2, so as to rupture the membrane and bring the contents of the recess 7 into contact with the liquid within the ampoule. The membrane may be secured, as shown, over a bulging lip on the pellet, or may be held by a ring fitting over a shoulder on the pellet or over the pellet as a whole. A modified ampoule is closed by a lined cap gripping its bulged neck. In a further modification, Fig. 5A, the closure member comprises a pin 24 secured to the flexible upper wall of the stopper and capable of being depressed as shown so that the point of the pin may be exposed within the ampoule. Fig. 7A shows a further modification employing a pellet with two recesses so that one chemical may first be dissolved and then a second chemical be added to the solution. When a bottle or like non cylindrical container is used the pellet may be mounted in a perforated tube attached to the cork, through which a pin may be thrust, or, as shown in Fig. 6A, the cylindrical neck of the bottle may have an internal flange 30b to support the pellet. Fig. 8 shows a further modification in which a square container is provided with a pellet having a number of recesses for chemicals and a corresponding number of pins in its top and bottom closures 38, 38<a> so that the contained chemicals may be dissolved in any desired order. The containers may be of various shapes in cross-section and the pellet may have rings whereby it is guided in movement on a skeleton frame within the container.

Title: Improvements relating to air compressors
Inventor: WILDE GEOFFREY LIGHT
IPC: F04D29/46
Filed: 1950-04-24
Abstract: 704,856. Centrifugal and axial-flow compressors ; gas turbine plant. ROLLS-ROYCE, Ltd. July 23, 1951 [April 24, 1950], No. 10101/50. Classes 110 (1) and 110 (3) In a compressor comprising a multi-stage axial-flow section followed by, and drivingly connected to, a centrifugal section, stator blading at the inlet end of the axial-flow section is adjustable to increase the whirl imposed on the air in the lower portion of the speed range. In a gas turbine engine, the compressor comprises an axial-flow impeller 18 followed by a centrifugal impeller 20, both mounted on a shaft 15 connected to the turbine rotor. Guide blades 22 and 23a and diffuser blades 24 are pivoted, preferably simultaneously, by means of hydraulic rams 29, 30 and 37 respectively so that on acceleration of the engine, the whirl imposed on the air by the blades 22 is decreased, the whirl imposed by the blades 23a is increased, and the areas of the diffuser channels between the blades 24 are decreased. In each set of blades, the blades are interconnected for simultaneous adjustment, as by means of radius arms 26 engaging slots in a rotatable ring 27, and pinions 35 meshing with a toothed ring 36. The rams may be similar to those described in Specification 704,849, in which the ram pistons withdraw into the ram cylinders as the rotational speed of the compressor increases. The control may be in accordance with factors which vary with the rotational speed, such as the compression ratio across the whole or a part of the compressor, or the corrected rotational speed (corrected, that is, for variations of compressor intake temperature as by including in the hydraulic governor system an orifice area controlled in accordance with the intake temperature). Instead of being continuous over a range of speed, the blade adjustment may be effected at a preselected speed.
