Title: Rock bit cone retention system
Inventor: SINGH AMARDEEP
IPC: E21B10/22
Filed: 2000-06-19
Abstract: A roller cone drill bit includes a bit body (32) Fig 2 adapted to be rotated about a longitudinal axis (L). At least one leg (36) depends from the bit body, and a journal (50) is cantilevered from the leg. A roller cone (40) is rotatably mounted on the journal. A cone retention member (70) is disposed between a first slot (72) in the journal (50) and a corresponding second slot (74) in the roller cone (40). An access hole (76) runs through the journal (50) to the first slot (72), penetrating the first slot at a location away from the top dead centre (78) of the first slot. The hole allows the balls to be inserted between the journal and the roller cone. The balls are retained in position by welding a ball plug (80) in the access hole. This arrangement moves the hole in the race from the high stress region. The cone retention member may be threaded rings.

Title: A method of producing a photographic image
Inventor: FYSON JOHN RICHARD
IPC: G03C7/30
Filed: 2000-06-28
Abstract: A method of producing a photographic image in an imagewise exposed photographic material which comprises one or more silver halide emulsion layers, comprises<BR> ```developing the material with a developer solution containing a silver halide developing agent,<BR> ```applying to the surface of the developed material a solution of a sulphite compound that reacts with oxidised developing agent and prevents further development, and<BR> ```applying to the surface of the developed material a solution of an oxidant that oxidises any remaining developing agent. The sulphite compound is present in an amount sufficient to react with all the oxidised developing agent. The solutions of sulphite and oxidant are applied to the material by means other than immersion in a tank. Development can be accompanied by an amplification step (REDOX amplification). The sulphite compound can by a hydrogen sulphite or a metabisulphite compound. The oxidant can be a salt of a peroxysulphuric acid eg peroxymonosulphuric acid (H<SB>2</SB>SO<SB>5</SB>) or peroxydisulphuric acid (H<SB>2</SB>S<SB>2</SB>O<SB>8</SB>). The solutions or sulphite and oxidant can be applied to the developed material by spraying from a fine nozzle, an air brush, an ink-jet head or by application with a roller.

Title: A device for inserting a tracheotomy pipe into a trachea comprising three elements movably connected to one another with a channel formed between the jaws
Inventor: GILMORE BRIAN
IPC: A61B17/34
Filed: 2001-05-22
Abstract: A device, for insertion of a tracheotomy pipe into the trachea of a patient, comprises three elements (2, 3 and 4) which are movably connected to one another between their ends (eg pivotally via a pin, 5), wherein one end of each of at least a first and second element comprises a curved jaw (8 and 9) adapted to cooperate with the curved jaw of the other element, and the other end of at least the first and second element comprises a handle (6 and 7), wherein the jaws comprise cooperating surfaces with a cavity formed between the jaws (preferably by a groove (10) formed at least in one surface of the jaw). The jaws (61, 62, 63, figure 4) of the device depicted in figure 4, however, are not curved. The third element may comprise a curved end (13) in the region of the jaws, the curvature of which may be opposed to the curvature of the other two elements. That end may be flattened. The third element may be connected to the other two elements pivotally and/or displaceably in a range of positions (eg via holes 25, figure 2) and in such a way that, when the jaws of the other two elements are moved apart, the end of the third element can be moved away from the jaws of the other two elements orthogonally to the direction of movement of those jaws. Fixing means may be provided for fixing the jaws in an open or a closed state. The groove (10) may extend partially along one jaw and terminate in an opening (10') on the side of the jaw. The cavity thus formed may serve as a channel for a guiding wire, along which the device may be introduced into the trachea of a patient. By moving apart the jaws or element ends, the opening in the trachea may be enlarged (prior to insertion of a tracheotomy pipe into the trachea) not only transversely to the trachea axis but also, using the third element, parallel to that axis.

Title: Apparatus and method for sealing an envelope
Inventor: CHAPMAN CARL
IPC: B43M5/04
Filed: 2001-09-28
Abstract: An envelope with its flap in an open position is driven along a transport path by transport means (31a). When the crease line between the flap and the body of the envelope reaches a predetermined location along the transport path, buckling means (31b, 53) engage the envelope from an opposite side, such as to cause the envelope to buckle laterally of the transport path and be partially closed. The buckling envelope with its crease line leading is then received by means (31a, 31b), which seal the envelope. The transport (31a) and sealing means (31a, 31b) are preferably driven rollers. Buckling means (31b, 53) may be a stop or a pair of oppositely driven rollers. A curved guide (51) may be used to induce the envelope to buckle.

Title: Micromotor
Inventor: MCKEVITT GARETH
IPC: H01L41/39
Filed: 2001-10-25
Abstract: An array 1 of micromotors 2 is formed from a sheet 3 of piezoelectric material. The sheet 3 is cut to define the micromotors as a plurality of elongate legs 5 which are connected together by a bridging portion 6 at one end of each leg 5 and which extend to the remainder of the sheet 3. The bridging portion 6 mounts a contact pad 7. The legs 5 are angled away from the remainder of the sheet 3. Each of the legs 5 has a pair of electrodes 8 extending along the legs 5 on the opposed major surfaces of the sheet 3 for applying an electric field across the sheet, the material being poled across the sheet 3 for activation in an expansion-contraction mode. In use, a periodic control voltage is applied across the pair of electrodes 8 for each leg 5 with a predetermined phase relationship between the control voltages for each leg 5. The resultant expansion and contraction of the legs 5 moves the pad around an orbital path allowing the pad 7 to drive movement of an object. The micromotors 2 are easy to manufacture by cutting and pressing a sheet 3 of piezoelectric material.

Title: Telescopic prop
Inventor: EBRAHIM M
IPC: E21D15/20
Filed: 2002-09-03
Abstract: A telescopic prop includes two sliding members where one of the members has a series of grooves on its outer surface which interact with circular pins (4) carried on the inner surface of a locking collar (5). In use, to extend or retract the prop, face plate (7) is pushed down which displaces laterally the circular pins (4) thereby disengaging the two members (fig 5).

Title: Optical connector with total internal reflection surface
Inventor: DAMES ANDREW NICHOLAS
IPC: G02B6/36
Filed: 2003-01-20
Abstract: A first portion of a connector is inserted in an existing waveguide section with a view to later upgrading the section as appropriate with one or more optical elements, e.g. OADM's, or amplifiers. When the need for an upgrade arises, a second portion of the connector is connected to the item which is required to be inserted into the existing section and the two portions of the connector then mated together as shown. In the mating process, a total internal reflecting surface of the first connector-portion, which in the existing fibre system simply reflects an optical signal back into the system, now passes the optical signal on into the second connector-portion and into the added optical element, thereby bringing that element into operation in the existing network with minimal disruption to network traffic. Another optical connector with a total internal reflection surface has means 312 for enhancing eye safe operation of the connector. A fluorescent material at 312 may provide a visual indication of the presence of an optical signal.
