Patent GB-2311233-A (GB)
Title: Continuous self-cleaning filtration unit
Inventor: WACHINSKI ANTHONY M
IPC: B01D24/00
Filed: 1995-12-12
Abstract: An improved vertical filtration unit (40) includes a bell-shaped lower end (62) for the air-lift tube (36), an injection ring (38) for introducing air into the air-lift tube at a considerable volume, and a washbox (84) with a more efficient scrubbing arrangement (44) for washing dirt particles from the filtration material. The bell-shaped lower end (62) makes the transporting of a mixture of dirty filtration material and water to the top of the filtration unit more efficient than with the conventional straight tube bottom. The tube receives compressed air from two horizontally positioned inlets (40) positioned 180{ from each other. The flat and round target plate (44) makes the scrubbing of filtration material more efficient, while a baffle (46) prevents the filtration material from being ejected from the washbox.

Title: Downhole data acquisition apparatus
Inventor: BESSON CHRISTIAN
IPC: E21B47/00
Filed: 1998-08-15
Abstract: A data acquisition apparatus for use in a wellbore comprises an array of sensing devices (22, 24, 26, 28, 30, 32) attached to the inner surface of casing (12) and a master unit (34) positioned towards the downhole end of a wellbore (10).

Each sensing device comprises a first transceiver, a processing unit, a second transceiver, a power supply unit and sensors. The sensors detect downhole parameters such as pressure, temperature, flow rate and resistivity. Signals from a sensor are processed in a sensing device and passed on to a sensing device further down the array. Here these signals are combined with the signals from the sensors in another sensing device and this combined signal sent onto further sensing units in a "bucket brigade" mode. These signals are subsequently passed along the array until they are eventually passed to the master unit (34) for transmission to the surface. Preferably the sensing units communicate using wireless telemetry such as acoustic waves.

Title: A method growing nitride semiconductor layer by molecular beam epitaxy
Inventor: HOOPER STEWART EDWARD
IPC: H01L33/32
Filed: 1999-06-12
Abstract: A method of growing a nitride semiconductor layer, such as a GaN layer, by molecular beam epitaxy comprises the step of growing a GaAlN nucleation layer on a substrate by molecular beam epitaxy. The nucleation layer is annealed, and a nitride semiconductor layer is then grown over the nucleation layer by molecular beam epitaxy. The nitride semiconductor layer is grown at a V/III ratio of 100 or greater, and this enables a high substrate temperature to be used so that a good quality semiconductor layer is obtained. In one embodiment of the invention, the substrate temperature during the step of annealing the nucleation layer is in the range 950-1050{C and the substrate temperature during the growth of the nitride semiconductor layer is within the range 900-1050{C.

Title: Adjusting unit
Inventor: SIEBER UDO
IPC: F16K31/06
Filed: 1999-08-16
Abstract: An adjusting unit comprises a deflecting device having a lever 5 which pivots about a first pivot point 6 and a connecting rod 11 which is connected to the lever for rotation about a second pivot point 12. The lever 5 is articulated by an armature 4 of an electromagnet 3. The connecting rod 11 performs a substantially linear actuating movement upon actuation of the electromagnet.

Title: Method for producing coloured, tissue-friend implants having oxyde-ceramic coating made from tantalum or niobium respectively from the alloy of these metals
Inventor: SZABO GYOERGY
IPC: A61L27/00
Filed: 1992-05-18
Abstract: Coloured biocompatible tantalum, niobium or alloy implants contg. these metals are coated by a chromic oxide layer in order to be used in bone sugary in facial and jaw operations for general surgical prostheses, securing elements screws and for dental roots. Prior to developing the biocompatible protective surface layer the raw implants are degreased, chemically or electrochemically etched and chemically polished. Implants prepd. from electronically (over 99.5%) pure tautalum or niobium, are subjected to vacuum heat-treatment for 30 mins. minimum, above 1680 deg.C temps. and 0.1-0.00 Pa pressure followed by anodic oxidation i.e. shaping. An oxide layer of 1000-2500 Angstroms thickness is developed as a first step at 85 deg.C in a dil. aq. electrolyte of less than 1% phosphate concn. by the application of a current density of 1 MA/cm2 or smaller. The thus oxidised implants are rinsed free from ions and die heat treated at 300-500 deg.C. for 5-120 mins. In a second stage, implants are oxidised further at low, pref. ambient, temp. in an electrolyte of higher concn. contg. 1-10 wt. % phosphate and at a current density of 2-10 MA/cm2 until an ultimate voltage develops that corresponds to the required oxide hue, i.e. required coatings thickness. Implants, that received the first oxide layer coating, are heat treated once more.

The platelets are 5 to 43 microns in size and the film is up to 0À075 inch thick with a visible light transmission of at least 80%. The film is made by blending the polyvinyl acetal resin with the metal platelets, heating to above the softening point of the resin, and extruding or compression moulding. A plasticizer such as triethylene glycol di-2- ethyl butyrate may be included. The metal forms 0À01 to 1À0% by wt. of the film. Laminates may comprise a sheet of transparent material such as glass, polycarbonate, or polymethylmethacrylate having a sheet of the film adhered to one or each side. Alternatively the film may be sandwiched between two sheets of the transparent material which in this case may be up to 0À5 inch thick. The transparent material may contain a light-absorbing pigment such as carbon black, or the laminate may contain a further layer of organic polymeric material containing a light-absorbing pigment, such as carbon black.
