Title: Automatic control of water level in open channels
Inventor: ATKINSON PETER
IPC: G05D9/12
Filed: 1987-02-10
Abstract: To regulate the level of water above weir gates located in open channels the level of the water above the gates is monitored continuously or periodically and a signal the magnitude of which is directly proportional to the level is compared with a reference signal. The resulting output control signal is used to determine by means of an appropriate algorithm which of the gates should be operated and to what extent to maintain the water level and to provide a corresponding demand signal. The demand signal is fed to a gate control circuit associated with the appropriate gate(s). The gate control circuit includes a motor for opening or closing the gate in response to a demand signal and a feedback loop incorporating a positional transducer. A river/canal system over a wide area can thus be controlled from a single location by controlling several gates simultaneously.

Title: Vehicle i.c. engine fuel control linkage
Inventor: THOMA FRANK
IPC: F02D11/04
Filed: 1987-08-05
Abstract: A transmission linkage between an accelerator pedal 1 and a control rod 3 of an injection pump includes a device 16 which acts on the transmission linkage to damp longitudinal vehicle oscillations by throttling back the injected quantity of fuel. To damp vehicle oscillations, which are caused by rapid retraction of the accelerator pedal, a damper 19 damps the return movement of the linkage components in the transition region from tractive to over-run operation of the engine. The damper piston 20 closes a piston bypass 24 as it moves towards the end of its cylinder 21 due to the action of the spring 7. A piston non- return valve 23 prevents damping action on pedal depression. <IMAGE>

Title: Intermittent feed mechanism for motion picture film
IPC: G03B1/22
Filed: 1951-01-10
Abstract: 681,279. Kinematograph apparatus. ALLEN, L. Jan. 10, 1951, No. 880/50. Class 97 (i). Intermittent film feed mechanism comprises a manually reciprocated push-rod which actuates a pivoted lever carrying a feed claw to produce the feed movements of the claw, the push-rod also actuating means to produce engagement of the claw with the film. In the viewing device shown, the feed mechanism is mounted in a shallow casing. A viewing lens 40 is mounted in the rear casing wall 2 and the film 26 passes in front of the removable front wall 10 in a groove in which it is retained by a translucent pad 32 held down by a spring-urged clip 36. A plate 11 secured to the wall 2 carries pivots 14, 15 for two levers 12, 13 pivoted in turn at 16, 17 to the push-rod 19 operable by a button 22 against a return spring 23. The end of the lever 12 is bent at right angles and shaped to form a claw 24 projecting forwardly through registering slots 34 in the front wall 10 and the pad 32. The end of the lever 13 is also bent forwardly at 27 to lie below and, at 28, behind the lever 12. The levers 12, 13 are loosely pivoted, but springs on the pivots 14, 15 urge the levers back against the plate 11. In this position the head of a rivet 29, in the lever 13, lies in a hole in the plate. When the button 22 is depressed the rivet rides out of the hole to force the end 27 of the lever forwards so that the portion 28 forces the lever 12 forwards to engage the claw 24 in the film perforation. At the same time the levers rotate to move the claw upwards, the lever 12 moving faster than the lever 13 because of the staggering of the pivots 14, 15. When the lever 12 moves clear of the portion 28, the spring at the pivot 14 moves the lever 12 back against the plate 11 to disengage the claw. The device has a storage compartment 8 with a removable cover 9.

Patent GB-900943-A (GB)
Abstract: 900,943. Measuring rotor unbalance electrically. AVERY Ltd., W. & T. Sept. 8, 1958 Sept. 6, 1957], No. 28702/58. Class 40 (1). Apparatus for determining the magnitude and angular position of the unbalance of rotors independently of their weight comprises means for lining up a known unbalance mass with that of the rotor, and determining the ratio of the unbalance of the rotor alone and that of the combined unbalance. As shown (Fig. 1), a test rotor 1 is driven by a motor 3 together with a selsyn transmitter 11, the unbalance being measured by pick-ups 7, 8. Initially selsyn 11 has its rotor energized with D.C., and the 3-phase A.C. at the rotational frequency induced in the stator windings are taken to the stator of a selsyn receiver 12, whose rotor is fed with the unbalance signal from pick-up 8. Thus the rotor of selsyn 12 lines up with the phase position of the unbalance of workpiece 1, and is clamped in this position, indicated by a pointer 14 and also transmitted through gears 17, 18 to the stator housing of a synchronous motor 19, whose rotor shaft carries a disc 28 on which is located an unbalance mass 29 of known magnitude, in an angular position corresponding to the zero reference position of selsyn 11. Thus the unbalance of workpiece 1 has the same angular relationship to the zero position of selsyn 11 as the unbalance mass 29 has to the displaced stator of motor 19. The rotors of selsyn 11 and motor 19 are now energized with A.C., and their stators interconnected by switch 22<SP>1</SP> and lead 19a so that they run as synchronous motors at the same speed as the workpiece 1. The disc 28 and mass 29 are mounted with motor 19 and selsyn 12 on a separate bracket 30 whose unbalance vibrations, due to mass 29, are in phase with those produced by the unbalance of workpiece 1, and are added by a spring rod 33, so that pick-up 7 measures the sum of the unbalances, whilst pick-up 8, located in a perpendicular direction, measures the unbalance of workpiece 1 only. The ratio of these two quantities is determined on a quotient-measuring instrument 27, and corresponds to the unbalance of workpiece 1 independently of its weight. An auxiliary mass may be added to the apparatus to neutralize any unbalance from mass 29 and its associated parts that may effect pick-up 8.

Title: Carbon black process control system
Inventor: BLAYLOCK CHARLES R
IPC: C09C1/48
Filed: 1990-07-03
Abstract: In a carbon black production process, input variables are controlled in dependence on a model of the process. The control system periodically predicts the values of output variables of the process which would result from measured values of input variables. The predicted values are averaged and input variables are adjusted in a sense to bring predicted output values towards reference values. Input variables include feedstock flow rate, feedstock quality, air flow rate, air humidity, air temperature, fuel flow rate, fuel quality, and/or potassium additive solution flow rate. Output variables of the carbon black, such as iodine number and/or DBP (Dibutyl Phthalate Absorption Number) are predicted. The predicted output variables are also laboratory measured from samples of the carbon black produced while the carbon black reactor is operating. The prediction algorithm is then adjusted to improve the accuracy of the prediction of the output variables, and thus produce carbon black of substantially consistent quality. <IMAGE>
