Patent GB-2136583-A (GB)
Title: Data transmission systems
Inventor: THORPE ANTHONY BERNARD
IPC: G01K1/02
Filed: 1984-03-12
Abstract: The value of a variable, such as temperature at thermistor 15, changing by small amounts and sensed at one location 11 is reproduced at a remote location 12 by transmitting thereto a signal representative of the difference between the sensed value and a reference value, and using the difference signal to control the reference value. A digital reference value held in an up/down counter 23 is converted to analogue form at 19 and subtracted at 18 from the sensed value, and the difference signal transmitter as a current over line 2 DEG c to A/D converter 24. If the difference signal as received by microprocessor 25 is greater than that corresponding to one increment of counter 23, a voltage pulse is passed back along line 2 DEG c, and via count-down switch 21 and pulse length discriminator 22, to increment or decrement the counter 23. The reference signal value which is stoned in microprocessor 25 for combination with the difference signal is similarly altered. True temperature is obtained using look up table 26. The difference and updating reference signals may alternatively be VHF and microwave signals. <IMAGE>

Title: Fluid filtering apparatus
Inventor: INOUE NOBORU
IPC: B01D51/02
Filed: 1986-06-13
Abstract: A fluid filtering apparatus wherein the surface of one of opposing electrodes 1, 7 is covered with a filter 10 made of dielectric substance. A voltage is impressed across said electrodes 1, 7 to polarize the filter 10 and thereby to generate a zeta potential on the surface thereof so that impurities such as colloid particles contained in fluid to be treated and introduced into a region between said electrodes 1, 7 are attracted by a Coulomb's force onto the filter surface. The colloid particles having lost the zeta potential at the filter surface cohere together to form a cake layer on the filter surface so that the cake layer thus formed on the filter surface provides for filteration with a precision higher than achieved by the filter itself. In other embodiments, an outer electrode (15, Figures 4 to 6) surrounds the charging electrode (1), the feed is introduced tangentially (Figures 7 and 8) or a plurality of inner electrodes is used (Figures 9 and 10). <IMAGE>

Patent GB-2197391-A (GB)
Title: Fuel system for gas turbine aero engine
Inventor: CANTWELL HUGH FRANCIS
IPC: F02C9/36
Filed: 1986-11-14
Abstract: A fuel pump (26) is provided with a pump spill return loop for recirculating through the pump any fuel already pumped but not passing through the metering unit (28). Such repumping of fuel can cause it to become excessively hot under some engine operating conditions and to avoid this the control unit (32') is made to produce both a normal fuel demand signal (30) in accordance with a normal control schedule and an alternative fuel demand signal (F), the latter being produced in accordance with an alternative control schedule (54) as a function of fuel temperature (t). The alternative control schedule is such that at fuel temperatures higher than a limiting value (tL), the alternative fuel demand signal is the higher of the two, and is selected to control the metering unit (28) by a "highest wins" logic (56), thereby reducing the heat input to the fuel by reducing the amount of fuel being recirculated and repumped. <IMAGE>

Title: Ground or crop treatment implements
Inventor: COUSINS JOHN
IPC: A01B29/06
Filed: 1986-11-26
Abstract: A Cambridge Roll or like agricultural or horticultural implement has in-line rear gangs 14, 16, and a front gang 18. The front gang is trailed from the tractor. The rear gangs are mounted on a common frame and effectively trailed from the front gang during work. The connection between the front and rear frames is through a ball joint 48 permitting both steering movement and contour following. The frames connecting the front and rear gangs can be rigidified for transport so that the three gangs are carried by the frame on power-lowerable transport wheels 32, 34. The rear outer gangs can be folded inwards for transport by hydraulic rams. In this way the advantages of a freely trailed implement with attendant avoidance of scuffing and easy turning are combined with the transport advantages of more recent frame-mounted implements. <IMAGE>
