Patent GB-2350852-A (GB)
Title: Downhole valve assembly for use during well operation and bore-drilling
Inventor: FRENCH CLIVE JOHN
IPC: E21B34/00
Filed: 2000-05-19
Abstract: In a well operating method, a valve is provided in a tubing string, closed to isolate the lower end of a bore and thus permit retrieval and replacement of the tubing string, and is reopened to permit fluid communication between the lower end of the bore and the tubing string. In a bore-drilling method, a drill string is passed through a valve in a casing, retrieved through the valve which is then closed to isolate the lower end of the bore and subsequently reopened. As shown, a downhole valve assembly 10 includes a hollow elongate member, preferably a tubular body 12, and a valve 18 which is operated by a fluid actuated valve control mechanism 14. A first hydraulic control conduit (41, figure 1) communicates with the valve control mechanism to open the valve and a second hydraulic control conduit is provided to close the valve. Preferably, the valve 18 is a circular plate (flapper valve) which, when open, locates in a cavity in a wall of the hollow member.

Title: Apparatus for producing a fleece from fibre flocks
Inventor: RUEBENACH BERNHARD
IPC: D01G23/06
Filed: 2000-05-19
Abstract: An apparatus for producing a fleece from fibre flocks has at least one substantially vertical shaft 9 of rectangular cross-section. A longitudinal wall 9b of the shaft 9 is air-permeable, and a multiplicity of elements 11 are arranged next to one another and distributed across the width of the shaft 9 for modifying the air flow prevailing in the shaft at those locations. In order to allow the usable width of the delivered web to be increased and waste at the edges to be reduced, the elements 11 are of relatively narrow construction in the lateral regions of the shaft 9 compared with a central region, and/or the spacing of the elements in relation to the shaft wall 9a located opposite increases towards the side.

Title: Releasable tube coupling device
Inventor: DOWLING MARTIN JOHN
IPC: F16L37/091
Filed: 2000-06-09
Abstract: A releasable tube coupling device includes a body 1 housing annual sealing means 5 for effecting a fluid-tight seal with an inserted tube 3 and an annular gripping element, eg grip ring 10, having a plurality of teeth (10b, fig 2) that grip the inserted tube to prevent accidental withdrawal or blow out. Prior to effecting the coupling with a tube, the respective internal diameters of the sealing means and the gripping element are substantially equal to or greater that the external diameter of the tube. The device further comprises an axially moveable clamping means, eg compression nut 8, which upon movement into an axially inner position causes both the sealing means and the teeth of the gripping element to resiliently deform into respectively sealing and gripping contact with the external surface of the tube while allowing them to go back to their original positions upon movement of the clamping means to an axially outer position.

Patent GB-2355534-A (GB)
Title: Measurement of toner level
Inventor: BAKER RAYMOND MILTON
IPC: G03G15/08
Filed: 2000-08-08
Abstract: The level of powdered toner (14) in a toner reservoir (12) of a printer or copier is determined by ascertaining the time that it takes a stirring paddle (17) to rotate from a second of two fixed ridges (15, 16) adjacent the top of the reservoir until the toner (14) is engaged. A sensor (22), which is preferably a piezoelectric element or a strain gauge, is preferably mounted on the end of the stirring paddle (17) to engage each of the two fixed ridges (15, 16). When the sensor (22) flexes after engaging each of the ridges (15, 16), two closely spaced electrical pulses are produced. When the sensor engages the toner (14), another electrical pulse is produced, and the time between the second and third pulses is used to determine the level of the toner (14) in the toner reservoir (12). If the stirring paddle (17) is flexible, it may engage the ridges (15, 16) and the toner (14) so that the sensor (22) could be mounted on the stirring paddle (17) to not engage the ridges or the toner but only to sense flexing of the stirring paddle (17) for producing the electrical pulses. Instead of using the ridges, an emitter wheel may be employed to produce a pulse when the stirring paddle is in its substantially vertical position.

Abstract: The heat conductance of the heat transfer route through which heat flows into a heat sink 3 from the central region and its neighborhood of an absorbent via the edge region of the absorbent is made to be smaller, by making the absorbent have such a form that the film thickness of the edge region of the pattern of the infrared absorbent formed on the surface of a temperature sensing part 1 is smaller than that of the central region of the pattern. Efficient temperature rise of a temperature sensing part is realized. The heat absorbing film is deposited using a mask 4 having an inclined opening edge 4c which may be spaced from the surface of the sensor.

Filed: 2002-08-20
Abstract: A juice extractor comprises a base 4 which supports juice cup 6, onto which is attached via a press fit, seat 25,26,27 for supporting a piece of fruit. Attached to the base is housing (3) which supports mounting bracket 10 and retains slide cylinder 15, to which is mounted press head 16. L shaped handle 8,32 is pivotally 12 attached to bracket 11 and is coupled to press head 16 via a link (17). Slide cylinder 15 has slots to accommodate bracket 10, handle 32 and link (17). Housing (3) also has an enclosed slot in which is disposed the handle.

Title: Method and apparatus for removing dust from a workpiece
Inventor: HOUGHTON STEPHEN
IPC: B23D59/00
Filed: 2003-03-13
Abstract: A jigsaw having a housing 4,6 and a support shoe 38 pivotable relative to the housing is disclosed. A bridge member 42 is mounted to the support shoe 38 and is connected to a connector piece 44 to define a conduit for transporting air from a duct in the housing, connected to a fan for cooling a motor in the housing, to a location at which a jigsaw blade of the jigsaw cuts though a workpiece. Actuation of a trigger 10 on the housing supplies power to a motor in the housing, which causes reciprocating motion of the jigsaw blade, and causes the fan in the housing to expel air though bridge member 42. Air is directed from bridge member 42 onto the jigsaw blade in a direction transverse to a line of cutting action of the jigsaw. This enables the outlet of bridge member 42 to be located very close to the jigsaw blade without obscuring the user's view of the blade, and blows dust away from the line to be cut by the jigsaw 2.
