Patent GB-2427093-A (GB)
Title: Digital filter design method and device, digital filter design program, and digital filter
Inventor: KOYANAGI YUKIO
IPC: H03H17/06
Filed: 2004-10-14
Abstract: For example, more than one FIR-type basic filters having a symmetric sequence of numbers having a predetermined characteristic as a filter coefficient are combined and connected In longitudinal connection. The filter coefficient is calculated and for the y-bit data of the calculated filter coefficient, the lower bit is cut off for rounding so as to obtain a filter coefficient of x-bit (x < y). Thus, it is possible to significantly reduce an unnecessary filter coefficient without performing the conventional window multiplication. Moreover, it is possible to realize a digital filter having a desired frequency characteristic with a small circuit size and with a high accuracy without causing a truncation error attributed to window multiplication in the frequency characteristic.

Title: Plasma cleaning of ion source electrodes in a mass spectrometer
Inventor: HOLLE ARMIN
IPC: H01J49/10
Filed: 2006-11-09
Abstract: The invention relates to the automatic cleaning of ion sources inside mass spectrometers, especially the cleaning of matrix-assisted laser desorption (MALDI) ion sources. The invention consists of filling the space within an ion source with a reactant gas, preferably containing oxygen, at a pressure of between 1 and 1000 Pa; and applying voltages, preferably RF voltages, to the ion source electrodes in order to generate a plasma in the reactant gas by means of a glow discharge; said plasma surrounds the ion source electrodes, reactively cleaning them by etching away material deposited thereon. The discharge may also be generated using auxiliary electrodes provided within the ion source, in particular a cleaning plate 11 which has the outer contours of a normal sample support plate.

Title: Drying apparatus comprising a magnetic base and an air blower
Inventor: RICHARDSON GARY
IPC: B05B15/658
Filed: 2007-01-22
Abstract: A drying apparatus comprises a base 3 incorporating a magnet 1 and having an adjustable shape-holding appendage which supports a compressed air blower 8. The blower is suitable for drying water based coatings such as paint. Preferably, the base is made from plastic and incorporates a padded rubber outer edge 2 which offers additional stability and protection whilst preventing damage such as scratching. The base may be bolted on to an air line housing 5 and detached by unscrewing so as to allow the encased air line and fittings 9 to be inspected. A compressed air line 4, running from a compressor, may be attached to the side of the air line housing with a standard air line connector comprising a shut valve. The air line inside the housing is attached to the bottom of an extendable telescopic hose 7 possessing '"stay-put" characteristics. The hose runs through a hard plastic outer tube 6, which may also act as a hand grip, and is attached to the blower with standard connectors. Preferably, the blower is made from stainless steel and is designed to draw air from the atmosphere as well as being supplied with compressed air. A thumb screw 10 may be provided to prevent the extendable telescopic hose from moving whilst the apparatus is in operation. For larger drying areas, two blowers may be operated simultaneously by using a split or 'Y' connector (13, fig.4) located on the extendable telescopic hose. Preferably, the drying apparatus is used to assist in the drying of car body paintwork. In use, the apparatus enables an operative to direct an air flow over a freshly painted surface by moving the magnetic base and/or adjusting the extendable telescopic hose.

Title: A selectively operational collet for use with a lock open tool
Inventor: STRATTAN SCOTT CLAYTON
IPC: E21B34/14
Filed: 2004-10-27
Abstract: A lock open device includes a selectively operational collet 81 having an upset 83, a collet attachment 85 and latch collet hold down 87. Attachment 85 communicates with recess 91 in latch mandrel in one of two ways. One way is that attachment 85 is engaged with recess 91 from start of operation and the tool is not in selective engagement mode. The second is that attachment 85 is not engaged with recess 91. In this configuration, latch collet hold down 87 is in communication with the upper latch collet 62 (figure 2b) urging collet profile 72 inwardly, which prevents engagement thereof with the profile 74 of a tubing retrievable safety valve (TRSV). This configuration would be employed when several TRSVs are in the well, and one deeper than the first is targeted. In the selective mode, the upset 83 is employed to release the collet 62 at the appropriate depth.

Title: Reduction of parameter and memory usage in tile based rendering system
Inventor: HOWSON JOHN WILLIAM
IPC: G06T15/00
Filed: 2008-03-19
Abstract: A method and apparatus are provided for reducing parameter and memory usage in a tiled based rendering system. Position data is retrieved from stored static geometry data in a memory and is transformed to screen space. The screen space position data is then used to compile a list of pointers to static geometry data in memory from which the position data was retrieved. This pointer data is then retrieved for each tile and the static geometry data corresponding to the retrieved pointer data is retrieved for each tile. Thus the retrieved geometry data is transformed to screen space and any attribute processing is applied to it prior to hidden surface removal and a transform data is then rendered to a buffer for display.

Title: Improvements in or relating to tappets
IPC: F16K31/00
Filed: 1937-04-08
Abstract: 493,456. Tappets ; valve gear. STEVENS, A. H. (Borg-Warner Corporation) April 8, 1937, No. 10030. [Class 80 (iii)] [Also in Group XXVII] Relates to hydraulic tappets suitable for cam mechanism wherein clearance is taken up by a substantially incompressible liquid filling a chamber between two relatively movable members. The members are telescopic, arranged to permit a slow contraction and a rapid extension and provide a first chamber filled with liquid, and a second chamber into which liquid slowly leaks from the first chamber. Resilient means tend to force the members apart and means are provided for eliminating any air or gas from the liquid returned to the first chamber. The tappet comprises a cylinder A enclosing a piston B which is loosely fitting to provide leakage. A plunger D which engages the valve stem has, at its lower end, a spider F engaging a shoulder G in the piston, and slides through a head E between which and the plunger is a sealing bellows H. The head of piston B has an aperture J controlled by a disc valve I, the downward movement of which is limited by a retainer K held against the piston by a loading spring L. This spring tends to raise the piston B to allow liquid to flow from the upper to the lower chamber through valve I and take up clearance. When the cam acts on the tappet, liquid is forced past the piston B into the upper chamber so that on the return stroke there is sufficient clearance to allow the valve to seat. This clearance is taken up during the rest interval by the spring L. It is important that no air bubbles be allowed to pass into the lower chamber and, to ensure this, the liquid is caused to pass through filtering material N, such as wool felt, supported on a screen M and held by a cup-shaped, member O with ports O<1>. Liquid is introduced through a hole Q afterwards closed by a plug R. In a modified construction, Fig. 3, the cylinder A<2> has a hardened hollow head A<3> engaging the cam S. The plunger D<1> is hollow and has ports D2, D<3>, of which the latter may be constricted to produce a dashpot action. The head E<1> has a depending flange E<3> which is a press fit in the cylinder and serves to trap a quantity of air therein which exerts a predetermined pressure on the liquid. Downward movement of the piston B<1> is limited by an annular member V. The filtering material is held by an inverted apertured cup W carried by the plunger D<1> and having a flange W<1> fitting the piston, the material being contained in a cupshaped screen M<1>. The valve I is preferably of light non-metallic material such as that known under the Registered Trade Mark " Bakelite." The loading of the springs L, L<1> is of importance and must not be such as to accelerate the mass actuated thereby at a greater rate than the acceleration of the valve by the valve spring.
