Alternatively, the wearing surface layer mix may be introduced into the mould followed by the mesh and lower layer. The composite mixture may be compressed under heat until set and composite is allowed to cure. The lower layer of polymeric mixture may be laid onto a prepared sub-base and allowed to set before or after the laying of the mesh. The composite is tamped and polish after the laying of the wearing layer and then allowed to cure.

Title: A power-on-reset pulse generator with zero quiescent current consumption
Inventor: DRUSENTHAL ULLRICH
IPC: H03K17/22
Filed: 2002-09-23
Abstract: A small-area power-on-reset (POR) generator circuit provides a pulse on output node A for a short period after power supply voltage VS has been applied to the circuit, which includes a capacitive voltage divider C1,C2,C3 and switching circuits IS1 and IS2. Switching circuit IS1 responds to the voltage signal coupled to node K1 from VS through C3 and C2 outputting a current signal to switching circuit IS2, which charges node K2 to complete a positive feedback loop. Output pulse length is determined by the discharging time of node K1 and/or the charging time of node K2. No current flows in the circuit when the output pulse has ended. A Zener diode voltage limiter may be connected to node K2 to shorten the output pulse and reduce the voltage stress requirement for C2 (figure 2). The circuits IS1 and IS2 may comprise current mirrors, which may operate in the subthreshold region. The capacitors C1 and C3 may be formed from parasitic transistor capacitances. The circuit may be used in a vehicle with a 42 volt supply. MOS or bipolar transistors may be used.

Title: Conveying apparatus with piezoelectic driver
Inventor: BAIRD RANDY K
IPC: B65G27/24
Filed: 2003-12-18
Abstract: A conveying apparatus 10 comprises an elongated conveying bed 12 which includes a proximal (left as shown) end and a distal (right as shown) end. A support structure 14, 16, 18 for the conveying bed 12 accommodates vibratory motion of a portion of the conveying bed 12 extending from the proximal end a substantial distance towards the distal end but dampens vibratory motion at the distal end. In addition, a piezoelectric driver 32 is operatively connected to the conveying bed 12 adjacent the proximal end. Consequently, operation of the piezoelectric driver 32 will induce a wave motion in the conveying bed 12 which will effectively convey a material from the proximal and to the distal end.

Title: Secondary radar mode S signal bit determination
Inventor: STEVENS MARTIN
IPC: G01S13/78
Filed: 2004-03-08
Abstract: A method and apparatus for determining a value of each bit in a secondary radar response pulse train sampled at a bit rate greater than one sample per bit is provided. The received signal is sampled repeatedly over a bit period. A scale factor for a weighting function is defined based on the amplitude levels detected from the response preamble. The weighting function has a maximum positive value at the expected bit amplitude for the first half of the bit period and decays to zero at higher amplitudes so that the effect of very large samples will be negligible. For lower amplitudes, the weighting decays to zero at the threshold level and becomes increasingly negative until zero amplitude. In the second half of the bit period the sign of the weighting function is swapped compared to the first half. The amplitude samples taken during the bit period are then each applied to the weighting function and the sum of the weighting function for the samples taken over the bit period is calculated. If the sum is positive, the bit is declared a "1"; if the sum is negative, the bit is declared a "0". The magnitude of the sum may be used as an indication of the quality or reliability of the bit decision. Multiple signals may be received at multiple antennas, whose outputs are combined with a phase shift chosen to suppress one signal. Alternatively model fitting can be used to degarble the signals.

Abstract: An atmospheric pressure chemical ionization (ACPI) ion source, able to optimally ionize both low to moderately polar and highly polar analyte molecules, comprising a housing 14 having a corona discharge chamber 1 connected to a reaction chamber 2 by a passage 6. Reagent ions are formed in the corona discharge chamber 1 and pass to the reaction chamber 2. Low to moderately polar analyte molecules pass from a heated tube 3 into the reaction chamber 2 and are ionised by ion-molecule reactions with the reagent ions. In contrast, highly polar analyte molecules are ionised by thermal ionization processes within the heated tube 3 and enter the reaction chamber as highly polar analyte ions. Analyte ions in the reaction chamber 2 are shielded from the electric field generated in the discharge chamber 1.

Title: Inlet valve for vacuum pump
Inventor: WICKES MATTHEW
IPC: F16K31/08
Filed: 2004-08-06
Abstract: An inlet valve for a vacuum pump comprises a housing 41 having an inlet 42, an outlet 44 spaced from the inlet, and a passageway 46 extending between the inlet and and the outlet. A moveable valve member 48 is located in the passageway for controlling a flow of fluid between the inlet and the outlet. The valve member comprises a first permanent magnet 56 and is moveable between a closed position at which the valve member sealingly engages a cooperating valve seat 50 and an open position spaced from the valve seat. The valve also comprises a second permanent magnet 62 which repels the valve member towards the valve seat. The repulsion force between the magnets serves to retain the valve member in the closed position until a pressure difference between the inlet and the outlet is of sufficient magnitude to cause the valve member to move towards the open position against the repulsion force between the magnets.

Title: Determining a radio link characteristic
Inventor: BARRETT STEPHEN J
IPC: H04W36/30
Filed: 2004-12-06
Abstract: A cellular communication system supports both soft handover communication channels and non-soft handover communication channels from the same user equipment (101). A serving base station (103) comprises a receive front end (201) for receiving transmissions from the user equipment (101). A first indication processor (203) receives a first link quality indication associated with a first signal of a soft handover communication channel from the user equipment (101). A second indication processor 205 receives a second link quality indication associated with a second signal of a non-soft handover channel from the user equipment (101). A characteristic processor (207) then determines the radio link characteristic in response to the first and second link quality indications. For example a transmit power control command (TPC) for a soft handover signal and a channel quality indicator (CQI) for a non-soft handover signal may be compared and a radio link quality may be determined in response to the comparison.

IPC: B60C23/04
Filed: 2002-10-09
Abstract: A system (10) and method (60) for monitoring vehicle (12) tire (14) pressure. A tire pressure monitor (16) for each tire (14) includes a pressure sensor (17) for sensing tire pressure (TP) and a transmitter (18) for transmitting a tire pressure signal (20) representative of the sensed tire pressure (TP). A receiver (22) for mounting on the vehicle (12) receives the tire pressure signals (20), and includes an antenna to be located at a vehicle site. Each transmitter (18) transmits tire pressure signals (20) periodically. A controller (24) for mounting on the vehicle (12) communicates with the receiver (22) and collects and processes the tire pressure signals (20). The controller (24) identifies the tire location (FR,FL,RR,RL) associated with a transmitter (18) and tire pressure signal (20) based upon the period associated with the periodic transmission of the tire pressure signal (20) from a tire monitor (16) located at the particular tire location (FR,FL,RR,RL) on the vehicle (12), to automatically identify the tire location (FR,FL,RR,RL) associated with each tire pressure signal (20). The controller (24) further generates control signals for use in conveying tire pressure (TP) and location (FR,FL,RR,RL) information to a vehicle occupant.
