Title: Improvements relating to register control of moving webs
Inventor: GOLD DANIEL
IPC: B41F13/02
Filed: 1954-01-14
Abstract: 759,059. Automatic registration control systems. CROSFIELD, Ltd., J. F. Aug. 13, 1954 [Jan. 14, 1954], No. 1164/54. Class 38 (4). [Also in Group XL (c)] Rapid correction is obtained in a registration control system for, e.g., printing-machines, by applying a large initial shift followed by a smaller reverse shift which leaves the net shift equal to the original error. As described, the two corrections are initiated, e.g. every fifteen revolutions of the printing-machine by a timing (pulse-counting) circuit. The magnitude of the shifts is determined by the rate of discharge of capacitors, charged by the error signal (as determined, e.g., by a photo-electric scanner). Initial shift.-Relay A is energized by a timing circuit, Fig. 4 (described later), to charge a 2 ÁF. capacitor 12 and a 4 ÁF. capacitor 13 in parallel from the error signal at terminals 10, 11. Relay A is then released to connect the larger capacitor 13, across the grids of a double triode 46 to operate either relay B or relay C, according to the sense of the error to (i) start the correction motor, Fig. 5, and (ii) connect the capacitor 13 through a resistor (55 or 59) to a point 57 of relatively high-potential, so that the capacitor discharges linearly determining the time (i.e. amount) of initial shift. Reverse shift.-After relay B or C is released by the discharge of capacitor 13, the timing circuit releases a relay to (i) reverse the connections to the correction motor; (ii) connects the 2 ÁF. capacitor 12 in place of the 4 ÁF. capacitor 13 to cause reverse rotation of the correction motor, for half the previous time. Timing circuit.-Negative pulses generated every revolution of the printing-machine are squared by a " flip-flop " connected doubletriode 15, and positive pulses from anode 19 are integrated by capacitor 31 and diode 33 to operate relay F after a predetermined number of pulses. Relay F (i) applies a " holding " bias to the double-triode 37, (ii) energizes relay A and charges a delay circuit capacitor 40 for controlling the reverse shift, (iii) discharges capacitor 31 thereby releasing relay F for the start of another cycle. Meanwhile, charging of capacitor 40 has energized relay H (in the cathode circuit of a double triode 44) causing its repeater, Fig. 5 (not shown) to (i) connect the correction motor to the control relays B and C for initial shift, and (ii) select capacitor 13 (Fig. 3). The release of relay H and its repeater to connect for reverse shift is determined by the time for capacitor 40 to discharge, which is affected by the speed of the printing-machine as represented by negative pulses from the anode 17 of the " flip-flop " circuit which are stored by capacitor 76. The capacitor 40 discharges fairly rapidly to the potential of tapping 80 in one cathode resistor of double-triode 44 (which is determined by the potential of capacitor 76), and then more slowly through resistor 52. Specification 641,830 is referred to.

Title: A method of operating grinding discs mounted to run coaxially in vertical planes
IPC: B02C7/18
Filed: 1921-01-10
Abstract: 157,374. Steinmetz, S. Oct. 7, 1915, [Convention date]. Processes for reduction of grain.- Grinding-discs mounted to rotate coaxially in vertical planes are so operated by changing the direction of rotation or speed, or both, that all the grain products, bruised corn, grits, and ground bran, are obtained in succession on one and the same pair of fluted discs. The discs, fluted as shown, are operated in six different ways, (1) by rotating the discs in opposite directions at different speeds, a flat meal or bran stripping is produced, there being no pressure; (2) by rotating both discs in the same direction at unequal speeds, grits are produced and rolled owing to the great pressure; (3) by rotating the discs in opposite directions at the same speed, there is sharp cutting without pressure producing meal-free groats or a coarse bran; (4) by holding one disc fixed and rotating the other quickly in a direction to cause the flutings to act against one another, there is produced without pressure meal-free groats or a coarse bran as in (3) but with reduced output; (5) with one disc fixed and the other rotating in the opposite direction to that of (4) a grits-like meal is produced at slow speed; (6) with the arrangement of (5) but at higher speed, a flat meal or flat bruised product is obtained.

Articles are made by charging a mould 10 with a mixture of a synthetic resin and a hardener therefor, from a supply vessel 20, which contains a predetermined quantity of material slightly in excess of that required for filling the mould, the resin and the hardener being fed in controlled proportions to a mixing device 36 and thence to the vessel 20, the feeds to the mixing device 36 being automatically brought into or out of operation when the quantity of mixture in the vessel falls below or reaches respectively the predetermined quantity. The resin and the hardener are fed from storage tanks 33, 35, respectively, through pumps 32, 34 to the mixing device. A motor 38 drives the pumps through reduction gearing 37 and pump 34 also through a variable gear 40, so that the proportions of resin and hardener in the mixture may be controlled. Alternatively, separate drive motors may be used. The motor 38 is controlled by a switch operated by a float 42 in the vessel 20 to keep the level of material in the vessel constant. The mould 10 is mounted on a vertically reciprocable table 12 operated by an hydraulic cylinder 14. On raising the mould the table engages with the resilient edge 44 of a vacuum bell 16, which is slidable on the vessel 20 against a spring 18. The bell and mould are then evacuated through a conduit 46. When the nozzle 22 of the vessel 20 engages with the sprue 24 of the mould, gas pressure, e.g. a few atmospheres, is applied through a conduit 23 to force the mixture into the mould. A core valve 26 operated by an air cylinder 30 closes the nozzle 22 except while the mould is being filled.

Title: An improved process for obtaining valuable distillates by the destructive hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1930-01-21
Abstract: In the destructive hydrogenation of fluent carbonaceous materials such as petroleum, tars, and suspensions of coal in oil, a portion of the reaction mixture is withdrawn from the reaction vessel and the pressure on this portion is reduced so that a substantial part of the hydrocarbon liquid is distilled.  Oil or the like, heated in a pipe still 1, passes to a reaction drum 3, from which a part of the oil is continuously re-cycled by a pump 6 back to the pipe still.  Hydrogen is pumped by a compresser 8 into the still through valve 11, and into the reaction drum through valve 12.  Vapours pass from the drum to a heat-exchanger 15 and condenser 16; hydrogen purified, if necessary, from hydrogen sulphide and gaseous hydrocarbons, is returned by a pump 18 to the pipe 10.  A part <PICT:0340811/III/1> of the reaction mass is withdrawn by a pipe 19 through a pressure reduction valve 20 to a vaporizing chamber 21.  Solid residues are discharged through a double bell closure 23<1>, and vapours are passed through a condenser 25 to a gas separator 26. Inert gas may be introduced through a valve 21a.  Fresh oil is introduced into the system by pumps 31, 33 through the preheater 15 and the pipe 34.  Carbonaceous solids may be added from a pulverizer 32, and oil from the separator 26 may be re-cycled through a pump 29.
