Inventor: OLSSON KENT
IPC: A61L27/42
Filed: 1999-03-19
Abstract: The invention refers to the composition, manufacturing and usage of silicon nitride as a biomaterial for medical usage as a surface carrying, orthopaedic biomaterial for wearing surfaces in artificial joints, for example the hip and the knee joint. The manufacturing is performed by preparing and mixing a mixture of powder containing 70-100 volume % silicon nitride with the addition of 0-30 volume % of one or a combination of the following materials: zirconium dioxide, yttrium dioxide, titanium dioxide, calcium oxide, silicon carbide and mullite. From the mixture a body is formed which is subjected to a high pressure greater than 50 MPa and temperatures between 500-3000  DEG C under sintering (HIP). The material can be used for one, both or all the wearing surfaces in an artificial joint.

Title: Sea wave machine for renewable energy
Inventor: ZACZEK MICHEL PIERRE
IPC: F03B13/22
Filed: 2001-02-07
Abstract: The sea wave machine for renewable energy comprises a sealed float 1 which has attached to its base a tube 6 housing an Archimedes screw 7 on a rod 2. The rod passes into the sealed float through a watertight bearing 5 and attaches to a flywheel 4. The tube has an opening 12 (or openings) at the top above the Archimedes screw to allow in water. In a wave the machine is lifted by the float and the weight of water in the tube pulls in the opposite direction to turn the Archimedes screw which transfers its rotation to the rod and flywheel. This rotational force may by various means be converted into electricity. Flap valve 9 closes when the machine sinks in the water.

Title: Electric infusion beverage maker
Inventor: SCOTT MICHAEL JAMES
IPC: A47J27/21
Filed: 2001-03-05
Abstract: A beverage making appliance 2 comprises a water heating vessel 4 provided with a thick film heater 24 on its base 20 and an infusion vessel 6 arranged thereon, containing in use a dose of infusant e.g. tea leaves. A tube 8 extends down from the infusion vessel 6 into water heating vessel 4. As water in the water heating vessel 4 is heated, the vapour pressure in the vessel 4 increases, with vapour escaping from the vessel 4 through a valve unit 46. When the water begins to boil, a ball 50 in the valve unit 46 is forced by the vapour pressure against its seat 54 to close the valve, forcing heated water to flow through tube 8 into the infusion vessel 6. Once transfer of the water is complete, a control unit 72 operates to disconnect the power supply to the heater 24. The steam pressure in the water heating vessel 4 begins to fall, and valve 46 reopens, allowing infused tea to flow back under gravity into the water heating vessel 4.

Title: Fire damper assembly, such as may be located in a duct, with breakable fusible link for emergency closure in response to elevated temperature
Inventor: MORGAN KEITH WILLIAM
IPC: A62C2/12
Filed: 2001-05-03
Abstract: A fire damper comprises a casing 10 and a damper blade 12, normally held open by a fusible link mechanism 32, comprising two relatively moveable components, 48, 50, such as flat plates, secured together by a fusible compound, and held within a guide member 44. The guide member 44 permits a controlled smooth sliding separation of the components 48, 50 in the event that a predetermined raised temperature, such as that caused by a fire, melts the fusible compound, allowing springs 16, such as tension coil springs, to close the damper. The fusible compound may be a solder compound. The damper may further include a system including a control box (fig.9) for non destructively disengaging the fusible link mechanism to test the integrity of the closure springs 16. The damper casing 12 may be circular (figs. 4 and 5). The damper may be used in ducting, such as that in a building, or directly in a building wall.

Title: Automatic turret bagging machine
Inventor: LIPES ARNOLD
IPC: B65B65/08
Filed: 2001-07-02
Abstract: An automatic turret bagging machine utilizes a turret transport mechanism having four article receiving compartments 11 to receive liquid pouches 16, herein milk pouches, oriented longitudinally therein. An indexing motor 31 drives the turret transport mechanism 10 between an article loading position 28, an article discharge position 15, an intermediate position 35 and an article unloading position 36. A control plate 29 is synchronized with the turret transport mechanism 10 and provides a support for a follower bearing member 40 secured to the trap door 34 of each of the compartments 11 whereby to retain and release articles loaded in the compartments 11. The control plate 29 also has a formation which automatically recloses the trap doors 34 of the compartment 11 upon reaching a predetermined position and simultaneously repositions the follower bearing member 40 with a lower surface of the control plate 29. In the event that an improper number of pouches 16 are loaded in a compartment 11, that compartment 11, will not unload at the discharge position and the bag opening and positioning mechanism will idle during one cycle step and the improper number of pouches 16 will automatically be discharged at the article unloading position 36 for recycling.

Title: An electric motor gear actuator with harmonic drive
Inventor: LEIN LARS
IPC: F16H49/00
Filed: 2001-07-19
Abstract: An electric motor actuator, for control of a gear selector mechanism, has a drive ratio of from -40:1 to -60:1 and comprises an electric motor 16 mounted coaxially inside a shift drum 40 driven by a harmonic drive. The harmonic drive comprises an elliptical wave generator 12 mounted on the rotor 14 and a flexible cup shaped spline gear 20 connected, eg by bolts, to the shift drum 40. Flexible spline gear 20 has fewer splines than an annular spline gear 24 and the wave generator 12 being of elliptical shape causes the splines of the flexible spline gear 20 only to mesh with the splines of the annular spline gear 24 at angularly spaced diametrically opposed locations. The shift drum 40 is supported by bearings 46 on a mounting member 32 which is fixed to a support member (208, fig 4). In another embodiment two electric motor shift drum assemblies are mounted coaxially on a shaft to form a double shift drum actuator (see fig 4).

Patent GB-2363908-A (GB)
Title: Thermally-responsive actuator
Inventor: O'NEILL ROBERT ANDREW
IPC: H01H5/18
Filed: 1998-05-27
Abstract: A steam sensor switch for an automatic kettle employs a snap-acting bimetallic actuator 12 to operate an overcentre arrangement by means of a push rod 13, the overcentre arrangement comprising a C-spring 1 and a trip lever 8 sprung between spaced-apart abutments. Spring contact elements are integrally formed with the C-spring 1 so that they pivot about a fulcrum when the overcentre arrangement switches between its two stable conditions and are not subject to mechanical deformation. This contact arrangement enables a large contact separation to be achieved in a small size switch and thereby enhances electrical safety. A second bimetallic actuator ensures operation of the switch if it fails to be operated by the first bimetallic actuator, the second actuator being shielded from steam generated when water boils in a vessel to which the steam control is fitted so that it will operate only after such a time delay as to give the first bimetallic actuator a chance to operate.
