Granted: 2011-06-14
Abstract: A sanitary pump with gear shaft bearing blocks in opposed cylindrical portions of a pump body bore, blocks constituting hand removable structural pump ends. Gear shaft bearings extending completely through blocks for easy cleaning, sealed by O-rings and clamp plates. Oval gear cavity bore between cylindrical portions of body bore extends only length of largest of interchangeable gears. Seals at end of gear cavity eliminate entrapment zones. Minimal intrusion of bearing blocks into gear cavity allows large operating temperature range. Shaft seals are contained in a hand removable cartridge. Complete pump disassembly by one manually operated clamp. Gear shaft diameters differ assuring correct assembly.  Mount receives pump, tie rods sealing pump and securing to mount. Mount allows pump removal without changing pump-drive alignment. Pin and groove engagement of pump to mount allows 90° interval pump ports orientation.

Abstract: A cosmetic powder container and insert which allows the consumer the option of either dispensing the powder through a sifter, or through an opening of sufficient diameter to accommodat e a brush without the consumer having to remove and discard the insert itself. The insert generally comprises a base (2) having an aperture, and a panel (6) having a plurality of perforations. The panel (6) is pivotally attached to the base (2) by a hinge . The panel (6) is capable of occupying a first open position and a second closed position. In the first open position, the panel (6) is pivoted to a position where the aperture of the base (2) is exposed and a brush can be used to apply the loose powder. In the second closed position, the panel (6) covers the aperture and allows the sifter to be used to sprinkle the powder through the perforations.

Abstract: When the length of the vertical synchronizing signal constantly differs from that of the standard signal, writing of data into the shuffling memory and readout of data therefrom are asynchronous so that overwriting and mixture of data will occur. To deal with this a memory for three frames is used for the shuffling memory. This makes it possible to effect shuffling without causing data mixture.

Abstract: This invention relates to a method and arrangement for controlling transmission power in a mobile communications system, and to a network element. In the method according to the invention a certain target level is defined for a value representing the quality of a signal, which target level should be reached by the received signal. According to the invention this target level is advantageously limited so as to be smaller than or equal to a first predetermined limit value and/or greater than or equal to a second predetermined limit value. In accordance with the invention the quality of the signal may be measured e.g. by means of an SIR  value. In the method according to the invention the quality of the received signal is checked and, based on the check, a first SIR  target level is given to a comparing element (21). By means of the comparing element (21) it is ensured that the said first SIR target level falls within predetermined limits. Based on the comparison, a final SIR  target level is given to a power control element (12) which produces a power control signal in order to adjust the transmission power.

Abstract: A fish grading device (1) is formed from an array of generally rectangular apertures (2), each of which is formed by two long tubes (3) and two short tubes (4) of plastics material mounted to a loop of fishing net (5). Each loop of fishing net (5) is formed by crimping the ends of the loop by means of a metal crimp (6). Each of the tubes (3, 4) can rotate freely about its longitudinal axis, so that a fish brushing against a tube (3, 4) will cause the tube to rotate, and will therefore avoid becoming snagged on the tube. When such a fish grading device (1) is included in a fishing net and the net is dragged through the water, small fish are able to swim through the rectangular apertures (2), whereas larger fish are not. Thus only fish of a desired minimum size are caught.

Abstract: The frequency error of an oscillator is minimized by characterizing the oscillator. A reference signal from an external source containing a minimal frequency error is provided to an electronic device. The external signal is used as a reference frequency to estimate the frequency error of an internal frequency source. The electronic device monitors parameters that are determined to have an effect on the frequency accuracy of the internal frequency source. Temperature is one parameter known to have an effect on the frequency of the internal frequency source. The electronic device collects and stores the values of the parameters as well as the corresponding output frequency or frequency error of the internal frequency source. The resultant characterization of the internal frequency source is used to compensate the internal frequency source when the internal frequency source is not provided the external reference signal.

Title: Stent-based venous valves
Inventor: DUERIG THOMAS W
IPC: A61F2/00
Filed: 2002-03-20
Granted: 2009-02-17
Abstract: An artificial venous valve which incorporates a stent having one or more of the elements comprising its frame deformed inwardly towards its center and a biocompatible fabric attached to the one or more elements is utilized to replace or supplement incompetent or damaged venous valves. The elements are deformed and the fabric attached in such a way as to form valve flaps, which when there is no pressure differential on opposite sides of the flaps, substantially occludes the lumen of the vessel into which the artificial valve has been deployed. When there is a pressure differential, albeit slight, due to the pumping of the heart, the flaps easily open and allow blood to flow therethrough while substantially preventing backflow.

Inventor: BUISMAN CEES JAN NICO
IPC: C22B3/14
Filed: 2003-12-23
Granted: 2012-03-13
Abstract: A new process of regenerating thiosulphate from a spent thiosulphate solution comprises the steps of: (a) reacting the spent thiosulphate solution with sulphide to produce elemental sulphur and a regenerated thiosulphate solution, (b) separating the elemental sulphur from the regenerated thiosulphate solution, (c) biologically reducing the separated elemental sulphur to produce sulphide, and (d) returning the sulphide from step (c) to step (a). This can. be applied in a process of extracting noble metals such as gold from a gold-containing slurry by contacting the slurry with a solution containing thiosulphate ions and oxygen to produce a gold thiosulphate solution, contacting the gold thiosulphate solution with an absorbent to produce a gold-loaded absorbent and spent thiosulphate, recovering gold from the gold-loaded absorbent, and regenerating the thiosulphate as described above.
