Patent GB-2333665-A (GB)
Title: Transaction system
Inventor: MCDONALD NEIL ANDREW
IPC: G06K7/00
Filed: 1998-01-24
Abstract: A transaction system comprises a terminal and a contact less token which communicate over an inductive coupling. Power and data are transmitted by the terminal to the token by a carrier signal. The token modulates the carrier signal by drawing more power from the signal. Data receiving means receives a first and second carrier signal, the first carrier signal being a version of the original carrier phase shifted 58 by +X‹ and the second carrier signal being a version of the original carrier shifted 60 by (X+ 180)‹. The first carrier is transmitted by the terminal and a signal containing the first carrier and the modulated signal from the token and the second carrier are summed 68 to produce a data signal. The token may be a smart card.

Title: Method of manufacturing a set of paving blocks
Inventor: ROBINSON JOHN REGINALD
IPC: E01C5/00
Filed: 1998-02-10
Abstract: A method of manufacturing a set of paving blocks for producing a circular paved area is described, the set including at least a first course and a second course having a different radius from the first course, the courses being selected such that the set can be manufactured from a single mould and can be assembled with a plurality of similar sets to produce a circular paved area. The method of manufacturing the set is such that the courses can be assembled with a plurality of similar sets in a circular manner with the sides of adjacent blocks parallel, thereby avoiding unsightly gaps that are difficult to fill. Figure 2 shows a set of blocks used to produce one sector of a paved area, eight of which would be required to give a circular effect, and Figure 3 illustrates how the set of blocks of Figure 2 is produced from a single mould.

Title: Drilling fluid
Inventor: REID PAUL IAN
IPC: C09K8/22
Filed: 1996-08-14
Abstract: A water-based drilling fluid (WBM) comprises as additive a reaction product of a polyhydroxyalkane and alkylene oxide. The polyhydroxyalkane is desirably based on a monosaccharide, and is preferably sorbitol. The alkylene oxide may comprise ethylene oxide (EO), propylene oxide (PO) and/or butylene oxide (BO). Good results have been obtained with additives including Sorbitol + 18EO, Sorbitol + 9PO, Sorbitol + 4EO + 6BO, Sorbitol + 6EO + 6BO, or Sorbitol + 6BO. Drilling fluids in accordance with the invention have been found in laboratory tests to exhibit improved shale inhibition properties as compared with known polyol containing WBM, particularly in the absence of added potassium ions. This is environmentally advantageous.
Patent GB-2324819-A (GB)
Title: Enhancement of flow rates through porous media
Inventor: DAVIDSON BRETT CHARLES
IPC: E21B43/16
Filed: 1998-03-24
Abstract: Apparatus for enhancing the flow of a liquid through a treatment volume of a porous medium, wherein the porous medium includes a solid matrix having pores which are interconnected and filled with liquid. The liquid travels through the treatment volume from a region of relatively high pressure to a region of relatively low pressure at a flow rate velocity of V. An operable pulse generating means included within the apparatus generates pulses in the liquid within the pores of the treatment volume, where each pulse causes a momentary change in the flow rate velocity, to a velocity substantially different from velocity V. This acts to keep the pores of the medium open, and if the pulses travel with the liquid, then the velocity of travel of the liquid through the pores can be increased. The pulses may be generated in the liquid without generating distortions within the solid matrix, and at a frequency that is fast enough to cause a progressive increase in the liquid flow rate with each pulse, up to a maximum velocity, substantially higher than a background velocity obtained when the pulse generating means is not operating. The pulses may be generated in an excitation well (40) which is separate from the extraction well (43), the pulses encouraging the movement of the liquid to the extraction well (43).

Title: An insulating plug for an electric discharge lamp
Inventor: MOCHIDUKI KUNIMASA
IPC: H01J5/56
Filed: 1998-12-01
Abstract: An insulating plug for an electric discharge lamp comprises: a front portion that has an outer cylindrical portion (33) and an inner cylindrical portion (31), wherein the inner cylindrical portion has an opening to receive an arc tube of an electric discharge lamp; a focusing ring (34) extending from the outer cylindrical portion of the front portion; and a rear portion having a cylindrical rear end portion (42) and a centre portion (43). The thicknesses of the rear cylindrical portion (t1), the front inner cylindrical portion (t2) and the front outer cylindrical portion (t3) obey the following relationship: t1>t2>t3. The front portion, the focusing ring and the rear portion are integrally moulded by injecting a synthetic resin into a mould through a gate in the mould. The gate faces the cylindrical rear-end portion of the rear portion of the insulating plug. The design of the plug cuts down the amount of plastic used to make the plug and also reduces the probability of any voids forming during the plug's manufacture.

Title: Transconductance amplifier with distortion correction arrangement
Inventor: MADNI ARSHAD
IPC: H03F1/32
Filed: 1999-01-09
Abstract: A voltage to current converter comprises a first long tail pair comprising transistors T1 and T2 whose emitters are connected via equal value resistors R1 and R2 to a constant current source CC1. The first long tail pair forms a main transconductance stage. A subsidiary or corrector transconductance stage is connected in anti-phase with the main stage. The corrector stage is based on another long tail pair comprising transistors T3 and T4 whose emitters are connected via resistors R3 and R4 to another constant current source CC2. The linear part of the transconductance of the corrector stage is substantially less than that of the main stage but the non-linear part is substantially equal to that of the main stage. Thus, non-linear distortion can be substantially reduced.

Title: Synthesis of a sine wave having continually variable frequency using PWM waveforms
Inventor: HUMPHREY FRANCIS ALAN
IPC: G01N29/00
Filed: 1999-06-17
Abstract: A stepped approximation to a sine wave 105 is generated by adding weighted PWM signals 102-104 having the same frequency as the sine wave to be produced. The PWM waveforms are generated from an input clock signal 101 so that the frequency of the output sine wave is adjustable by varying the input clock frequency. The PWM waveforms may be produced by a microprocessor (figure 7) clocked 111 by the output of a voltage-controlled oscillator (figure 8). Frequency swept sine wave outputs may be applied to a loudspeaker on a spherical resonator (figure 2) in order to measure gas sound velocity by measurement of the resonant frequency. The sweep direction may be reversed and the measured resonant frequencies averaged.
