Title: Vibration damping/endplay adjustment/mounting in an electric motor
Inventor: HWANG JANG HWAN
IPC: H02K5/10
Filed: 1996-12-10
Abstract: A motor, for example, for a vehicle, has a pair of friction washers (8a, 8b) inserted onto its armature shaft (S) for reducing the vibration of sintered bearings (5a, 5b) supporting the armature shaft and preventing oil from being sprayed. Each friction washer (8a) has a circular dishshaped extension surrounding a respective bearing, and protrusions (80) received in grooves associated with the shaft (S) or with a commutator (4) carried thereby. The use of such friction washers reduces the number of parts in the motor and prevents slippage whereby the thrust gap is maintained. A brush holder stay (31), to which a brush holder (30) is fixed, is fixed to the motor housing (1) by way of a rubber damper (9). This reduces the resonance of the brush holder and prevents chattering noise (brush noise) being transferred to the housing. A mounting bracket is disclosed.

Title: Motion compensated video signal interpolation
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: H04N5/44
Filed: 1993-04-08
Abstract: In a motion compensated video signal processing system (Figure 1) a pair of pixel interpolators receive both the selected motion vector and a flag indicating motion. One interpolator is employed when there is little or no motion and weights equally by a factor 0.5 the blocks of video data used for interpolation, 760 - 790. Furthermore the input video data is intra-field filtered by static coefficients 720 to interpolate additional pixels (610, 620, Figure 7) prior to inter-field interpolation. When the motion flag indicates motion, the video data from two fields is weighted by factors t and (1 - t) according to the temporal position of the output field and the intra-field weighting is by a different set of motion coefficients.

Title: Currency validator
Inventor: YELLOP ANDREW MICHAEL
IPC: G07D7/00
Filed: 1997-11-28
Abstract: In a method of validating articles of currency, preferably coins, the measured properties of an article are checked against a plurality of sets of criteria, each set corresponding with a predetermined acceptable type of article, and in each validation operation an inserted article is only checked against a group of sets of criteria selected from said plurality of sets prior to the making of an accept/reject decision. Further sets of criteria may be considered after the accept/reject decision, and if met are automatically enabled during a subsequent validation operation. Alternatively recognition of a coin from a particular currency may enable the sets corresponding with that currency, or the method may involve keeping a count of acceptable coins and enabling those sets associated with the coins most frequently encountered.
Patent GB-2318838-A (GB)
Title: Pump for dispensing viscous material
Inventor: TOPPER ROBERT T
IPC: B67D1/10
Filed: 1994-12-02
Abstract: A reciprocating piston has coaxial inner and outer piston members 138,140 which are movable along a piston rod 78 relative to each other to act as a one-way valve. Upon movement of the piston within a cylinder 86 in a dispensing direction, material contained therein, such as ice cream or the like, is pressurised out of a dispensing nozzle 188 whilst simultaneously new material is sucked into the cylinder from a collapsible container 40. A shearing action between an inner annular surface 144 of the outer piston 140 and an outer cylindrical surface 162 of the inner piston 138 is generated as they move into sealing engagement with each other and helps to cut through or deform particulate material obstructions between the two. Upon movement in a reverse direction, the two piston members 138,140 move apart to allow the piston to pass through previously suctioned material within the cylinder. The pump may be motor driven.
Patent GB-2334861-A (GB)
Title: Testing digital modulation systems
Inventor: NOKES CHRISTOPHER RYAN
IPC: H04L1/24
Filed: 1998-02-27
Abstract: The noise floor of e.g. a digital broadcast television receiver is determined, by connecting it in an artificial difficult channel. A modulator 10 supplies a signal to a low noise floor transmitter 42, the output of which is combined with the output of a variable noise source 46 in a combiner 44. The resultant signal is applied to the receiver under test 50, the output of which is monitored by a bit-error ratio meter 48. The amount of noise which can be added with the meter showing a predetermined bit-error ratio is noted. A first measurement is made with the modulator operating normally. The modulator is then changed so as to operate on every nth bit to cause the generation of valid but incorrect transmitted values, by forcing every nth bit to take the value 1. A second measurement of the amount of noise that can be added is then made. The noise floor Px can be determined from the difference between the two measurements. The method can be used to determine other errors and artefacts, and can be used to determine the transmitter noise floor instead of the receiver noise floor.

Patent GB-2339958-A (GB)
Title: Time of flight mass spectrometer
Inventor: DAVIS STEPHEN CHARLES
IPC: H01J49/40
Filed: 1998-07-17
Abstract: A time-of-flight mass spectrometer, for example, a MALDI-TOF spectrometer, measures the characteristics of the charge to mass ratio of ionized particles by measuring the time taken for the particles to travel a pre-determined distance. The spectrometer comprises an accelerator (14) which accelerates the particles along at least two paths, which may be contained in a single beam of charged particles. Two detectors (26 and 30) mark the ends of the paths and are operable to detect the particles travelling therealong. The length of the path leading to the first detector (26) differs from that of the path leading to the second detector (30) to a sufficient extent to enable the difference in detection times of corresponding particles at the two detectors to be used to provide a measurement of said characteristics. Variations in initial velocities and/or ionization times of the particles will have similar effect on the outputs of both detectors so that one detector can, in effect, be used to calibrate or correct the output of the other detector.
