Abstract: 1301660 Automatic control DEFENCE SECRETARY OF STATE FOR 15 Sept 1970 [15 June 1969] 24873/69 Heading G3R A control system comprises two channels having a common input and output in each of which an error signal, derived from the difference between the common input and feedback from the output, operates an actuator, the mean of the two actuator drives producing the output and the difference producing a signal which is added to the error signals in opposite senses to equalize them. In Fig. 1 the fuel throttle valve 11 of a gas turbine 10 propelling an aircraft is controlled through two channels A and B by identical signals from a pilots' control lever 72 and/or other flight data 73 from which computers derive control signals 13. These signals are compared at 30 with feedback signals 31 dependent on throttle position or, alternatively, dependent on engine combustion pressure or airspeed, so that the throttle 11 is controlled by difference signals 33 to maintain one of those quantities at a value dependent on the control signals. Signals 33 control electric motors 15 which operate differential gearing 16 so that a mechanical output dependent on the mean of the two motor outputs adjusts throttle 11. Any difference between the movements of the two motors, e.g. due to a fault, is detected by a further differential gear 40 which operates a transducer 51 to apply electrical signals 52 to the two channels in such senses as to equalize signals 33. Signals from transducer 51 exceeding a predetermined value, e.g. for more than a predetermined time, may operate warning indicators and, at greater differences, differential gear 40 operates limit switches to de-energize the motors and brake them. At still greater differences movement of transducer 51 by differential gear 40 is prevented by a stop which is automatically withdrawn by a solenoid if it is desired to operate one channel only by operation of appropriate switches after detection of a fault. When only one channel is operating its gain is doubled and feedback 52 is disconnected. Application to fluid pressure and velocity type signals is referred to.

Abstract: 1307228 Fertilizer compositions FISONS Ltd 14 Sept 1970 [7 Oct 1969] 49227/69 Heading C1B A suspension fertilizer composition comprises an aqueous suspension of a crystalline phase which consists predominantly of ammonium nitrate crystals in an aqueous solution saturated with ammonium nitrate and which contains another water soluble fertilizer ingredient, e.g. urea, ammonium phosphate, ammonium sulphate, potassium chloride, potassium phosphate, potassium nitrate or ammonia. The ammonium nitrate crystals of the above composition have undergone modification and/or growth inhibition so as to ensure that such growth as may take place gives rise to predominantly short stubby crystals. The-modification is caused by a controlling compound which is one of the following dyes, tartrazine, carmoisine S, elite fast red G, alizarine brilliant blue B, alizarine pure blue B, or the dyeing aid available under the trade name of Leveller T. In general, between 0À005 and 1À0% by weight of the controlling compound. A process for producing the fertilizer comprises mixing aqueous solutions and finely divided powders of the various desired ingredients in their final form rather than by forming the derived ingredients in situ. Such compositions are easier to spray than conventional compositions wherein crystal growth tends to cause nozzle blockage.

Filed: 1970-06-05
Abstract: 1308649 Automatic position control ARMCO STEEL CORP 5 June 1970 27247/70 Heading G3R [Also in Division H4] A method of sewing the position of the edge of a moving strip comprising the steps of beaming sonic energy across a predetermined path of the edge from a transmitter to a receiver capable of producing fluidic signals and causing fluidic signals generated by variations in said energy due to displacement of the strip to effect relative corrective movement to restore said strip edge to said predetermined path. A finishing process, Fig. 1 (not shown), comprises passing a steel strip through a bath of molten metal and thereafter subjecting the coating to air or steam from air knives on each surface to smooth the coating. The air knives 3 have vanes 6 at each edge of the strip 1 in order to increase the wiping effect. The vanes 6 are mounted on a slide 9 movable along a rod 10. The slide 9 is fixed to a second slide 17 which carries an ultrasonic whistle 13 fixed to a bracket 16. Air from conduit 26 excites the whistle 13 and the vibrations are detected by "fluidic car" 14 which is also fixed to bracket 16. Deviation of the strip 1 edge from its desired position causes a change in the low-pressure pneumatic output signal through conduit 29. The signal is converted to an electrical signal and used to drive screw 21 through shaft 25 and gearbox 24. Screw 21 moves nut 22 thus adjusting the slides 9, 17 and re-establishing the correct position of the vanes 6 relative to the strip 1 edge. The strip may be allowed to move within a predetermined zone one eighth of an inch wide before correction takes place. The zone is divided into two equal strips by the predetermined edge path and the edge is corrected until it lies in the remote strip from the error zone into  which it has strayed, Fig. 3 (not shown).

Filed: 1999-09-14
Abstract: Transmission power in a frequency-hopping radio system that transmits packets from a sending radio unit to a receiving radio unit, wherein each packet includes an address designating the receiving radio unit, is controlled by measuring received signal strength of packets whose addresses were successfully received in the receiving radio unit, regardless of whether other portions of the respective packets were successfully received. An average signal strength value is generated from the received signal strength measurements. The mathematical difference between the average signal strength value and a target value associated with the receiving radio unit is then determined and used as a basis for deciding whether to send a power control message from the receiving radio unit to the sending radio unit. In order to provide a hysteresis in the power control process, a power control message is sent from the receiving radio unit to the sending radio unit if the mathematical difference is greater than a first decision boundary, or if the mathematical difference is less than a second decision boundary. The power control message may itself include the mathematical difference which, when received by the sending radio unit, is used as a basis for determining a transmission power level adjustment amount. The target value, against which the average signal strength value is compared, may be based on the receiver sensitivity adjusted to account for implementation losses and other inaccuracies.
