Title: Conveyor drive apparatus
IPC: B65G23/14
Filed: 1962-01-05
Abstract: A conveyer drive mechanism 12 co-operates with a flat conveyer belt 1 formed of a flexible mesh fabric, preferably of metal, comprising a plurality of tractive links 2, Fig. 2, pivoted together by tractive pins 3. Each pair of adjacent members 5 form a wedge-shaped structure with the members connected across the narrow end of the wedge so that the belt is longitudinally collapsible to enable it to travel round lateral curves. A pair of endless chains 17 driven by suitably powered sprockets (not shown) has a number of rods 18 mounted thereon by pins 19 to permit pivotal movement of the rods about their own axes. Each rod 18 has a number of driving dogs 21 and has cam follower rollers 23, 24. As the rods 18 move upwardly roller 24 rides round axle 14 and engages cam surface 31 to hold its rod 18 in a rearwardly rotated position with its dogs 21 out of contact with the drive surface of rod 3 while the dogs enter the pockets 22. When roller 24 drops off the end of cam surface 31, dog 21 falls against rod 3 but with no driving force because of a cut-away portion 32 of a cam surface 29. When roller 24 meets the straight portion 33 while roller 23 rolls along a straight portion 28 of a cam surface parallel to the conveyer belt 1, the driving load is taken by the rod 18. At the end of the drive section the driving load is removed from rod 18 by roller 24 rolling along a cut-back section 34 of cam surface 29. As roller 24 contacts a cam surface 37, rod 18 is rotated to bring the dogs 21 out of contact with rod 3. The dogs 21 are withdrawn from the pockets 22 by roller 23 rolling down a cam surface 36. The arrangement is such that only one rod 18 drives at any one time, except at the instant of change-over, the action of the mechanism ensuring a smooth transition of the drive from one set of dogs 21 to the next set. U.S.A. Specification 2,872,023 is referred to.

Title: Interacting control of distillation
IPC: C10G7/00
Filed: 1967-05-18
Abstract: In a system for automatically controlling a refinery process, each of a plurality of signals, dependent in magnitude and sense on deviations of a plurality of process variables from desired values, is applied, after suitable modification, to control more than one of a number of other process variables each of which is thus influenced by a number of signals to restore the first mentioned variables to their desired values. In Fig. 1, crude oil is supplied to a fractionating column 1 at 3, and the top products pass through a condenser 5 to a separator 7 so that fuel gas may be taken off at 9 and the liquid, e.g. gasoline, partly taken off 13 and partly returned as reflux through a conduit 11. Fractions having higher boiling points, e.g. kerosene and diesel oil, are taken off as sidestreams at different levels through conduits 15, 17. The bottom products are taken off at 19. Signals corresponding to the flash and end points of the upper sidestream and the end point of the lower sidestream are respectively derived by units 23, 24, 25. These signals are applied to digital or analogue computer 21 which controls the datum of a controller 27 which stabilises the overhead temperature by control of reflux, and the datum of controllers 29, 31 which stabilise the rates of flow of the sidestreams. Within computer 21 each of the three input signals produces three control signals, one for each of the three controllers, and the computer is programmed so that each of these signals is proportioned to suit the static and/or dynamic characteristics of the control systems which are determined by step function application and frequency response techniques which may involve a model of the process. The three control signals for each controller are then combined and effect control with minimum interference between the control systems. Application to the control of catalytic cracking is referred to.

Patent ES-343547-A1 (ES)
Title: Improvements in the production and use of battings
IPC: D04H3/02
Filed: 1967-07-28
Abstract: A process for the production of a batting comprises continuously feeeding on to a moving surface a continuous web of crimped filaments which are generally parallel to the length of the web, which web is traversed across the surface to be deposited in partly overlapping folds, gaseous currents being used to determine the length of the web laid before each fold occurs. The web may be fed to the moving surface through an oscillating chute which confines the web sufficiently for a current of air to emerge with the web and carry the web beyond the point it would reach at the end of each oscillation by falling from the chute. Alternatively, the chute may be stationary, and gaseous blasts may be directed towards the web to force it beyond the position it would take in free fall. A pad for filling a cushion or like article is preferably made by folding or rolling a randomly folded web inside a batt made by the above process.

Patent ES-357802-A1 (ES)
Title: A process and system for measuring radiation doses using an ionisation chamber
IPC: G01T1/15
Filed: 1968-09-03
Abstract: Charge collected by an ionization chamber 1, 2 is integrated in a capacitor 5, and when the voltage across this capacitor reaches a pre-set valve, threshold circuit 7 supplies a pulse to counter 10 and causes a switching circuit 3 to reverse the polarity of the chamber 1, 2 or that the sign of the charge collected is reversed, the voltage across capacitor 5 then changing in the opposite direction until threshold circuit 7 is again switched and the cycle is repeated. A compensating capacitor 4 eliminates the effects of parasitic charges when switch-over occurs. Because capacitor 5 is not discharged after each charge increment has been accumulated, high speed, solid state switching is possible (detailed circuits are given) and dielectric hysteresis effects are avoided. The two threshold levels of circuit 7 also provide temperature compensation.
