Title: Sensors for neutral molecules
Inventor: BEER PAUL
IPC: C08G61/12
Filed: 1994-10-18
Abstract: A method for the detection of chemical agent present in a material comprising exposing a calixarene, having redox active substituents on its para rim, to a solution or suspension derived by admixture of all or some of the material with a liquid, measuring any change in electrical behaviour of the calixarene during or after exposure to the solution or suspension as compared to a reference condition, and relating such change in electrical behaviour to the presence of chemical agent. Preferably, the calixarene exposed to the solution or suspension is a calix[4]arene of general formula (I), wherein Y 1 to Y 4 are independently selected from hydrogen, alkyl, alkenyl, aryl, aralkyl or a redox active substituent and R 1 to R 4 are independently selected from hydrogen, alkyl, alkenyl, aryl, aralkyl, or a polymerisable moiety, wherein at least one of Y 1 to Y 4 is a redox active substituent.

Title: Power-up reset in semiconductor devices with back bias voltage
Inventor: CHO IL-JAE
IPC: H03K17/22
Filed: 1996-05-15
Abstract: A circuit generates a power-up reset signal in a semiconductor device which comprises MOS transistors of first and second channel types. The circuit comprises a back bias voltage generating unit for supplying a back bias voltage to a substrate of a second channel type MOS transistor when a level of an input supply voltage Vdd is higher than the sum of a first threshold voltage of the first channel type MOS transistor and a second threshold voltage of the second channel type MOS transistor; and a pull-up unit 1, 2 connected between terminals of the supply voltage Vdd and a reference potential Vss for generating a power-up control signal intended to rise when the level of the supply voltage Vdd becomes higher than that of the first threshold voltage. A first MOS transistor of a first channel type outputs the supply voltage as a reset signal in response to an initial input of the power-up control signal; and a reset signal output control unit 5 is connected between the reset signal output path and the reference potential terminal Vss, to cut off an output of the reset signal in response to an input of the back bias voltage.

Title: Mixing and milling solid particles suspended in a liquid
Inventor: WILD MARK
IPC: B02C17/16
Filed: 1996-11-01
Abstract: A head 14 for mixing and milling a mixture such as paint or printing ink in which solid particles are suspended in a liquid comprises impeller blades 44, 44' and 48 and a toroidal milling chamber 22 that contains ceramic beads 62. The blades break up agglomerates in the mixture and impel it through holes 64, 66 and 68 into the milling chamber. The flow of mixture into the milling chamber agitates the beads so that solid particles are ground between them. The liquid with ground particles leaves the milling chamber through holes 70 in the outer wall and creates turbulence around the head which breaks down agglomerates in the surrounding mixture. Blade 44' may have an additional rotor 45 for generating additional shear and turbulence in the mixture.

Title: Synchronous demodulator
Inventor: LEHNING HEINZ
IPC: H04L27/233
Filed: 1997-10-03
Abstract: A synchronous demodulator 10 receives an RE signal 11 and demodulates the signal into in phase and quadrature baseband data. The in phase and quadrature baseband data are used to adjust the phase of subcarriers 58,59 to ensure that the subcarriers and the received signal have the same phase. The phase of the in phase subcarrier reference is inverted when the in phase baseband data signal is not in phase with the quadrature baseband data signal. Similarly, the phase of the quadrature subcarrier reference is inverted when the quadrature baseband data signal is not in phase with the quadrature baseband data signal. The demodulator may be used to demodulate modulated signals from a smart card.

Title: Sensor arrangement
Inventor: SAVILLE DAVID ROY
IPC: B60R21/01
Filed: 1998-03-27
Abstract: A collision sensor arrangement for a motor vehicle comprises a collision sensor 2 for operative connection to an airbag in a side of the vehicle.

Title: Method of manufacture of a nonwoven fabric
Inventor: LAW STEPHEN JOHN
IPC: D04H3/015
Filed: 1998-06-05
Abstract: A nonwoven cellulose fabric is manufactured by extruding a solution of cellulose through at least one spinning jet to form fibres, subjecting the fibres to a high velocity gas flow, and passing the fibres through a vapour mist which at least partially coagulates the fibres prior to collection as a fabric web.

Title: Automatic answering for some telephone-network calls
Inventor: BROWNLIE JOHN DAVID
IPC: H04M1/715
Filed: 1998-08-24
Abstract: A telephone-network signals calls to destination terminals by either of two categories of ON/OFF ringing signal: one category, fig. 2, called a short-ring and having ON periods less than a time-interval T, is used to signal calls intended or automatic answering; the other, fig. 1, having ON periods longer than T, is used to signal telephony calls which need the attention of a person from the outset. Equipment at the terminal can initially prevent audible or other telephony alerting while seeking assured detection of one or other specified short-ring cadence and then provide prompt automatic answering, and alternatively enable audible or other telephony alerting as soon as an ON period exceeds T. Various approaches can determine the choice of ringing signal for a particular call.

Title: Energy saving ventilation in buildings
Inventor: STEPHENS DAVID HUW
IPC: F24D3/00
Filed: 1999-07-06
Abstract: An integrated system for saving energy and passively collecting solar heat gains in buildings reduces heat loss through glazing both by trapping cold air between glazing and insulating panels or shutters so preventing room air from convecting against the shuttered area of glass, and by admitting fresh air to ventilate the building at the head of glazing and constraining it to flow downwards over the inner glass surface. Sustainable heat is extracted by cooling outgoing stale air to below external temperature with an air to water heat pump. The warm water produced may be circulated through a container serving as a combined hydronic "radiator" and solar panel fitted between two window shutters, the innermost being raised to transfer heat to the room. The outer shutter may be raised to allow the solar panel function of absorbing radiant solar energy towards heating domestic hot water.

Title: Crop cascade fall-breaker
Inventor: CRICHTON DAVID JAMES RICHARD
IPC: B65G11/08
Filed: 1999-09-25
Abstract: A frame 1,2 of the device is bolted to the end of a conveyor so that it automatically moves to maintain the correct position when harvesting,(fig. 1. (1)). From the frame hang three adjustable chains 3 on either side supporting three soft mats stepwise. The mats are angled so that the crop runs slowly from mat to mat and into container. The slope of mats is adjustable by means of the chains to suit varying crop conditions. The top two mats have side panels 5 to eliminate lateral fallout of the crop on steep gradients but allows the operator to observe the moving crop. The design allows for automatic retraction for road travel.
